core tip: "... Many companies have established a set of perfect policies and guidelines to improve the skill level of workers, but few companies implement strategies to reduce the skill level required by mold change itself." -- Xinxiang Chongfu (the founder of rapid model change and one of the founders of Toyota Production System)
[China Packaging News] with the industrial revolution and the continuous upgrading of science and technology, the topic of "unmanned" has become popular on Mars, and new words continue to hit our eyeballs and refresh our cognition. Unmanned manufacturing is rapidly impacting the manufacturing industry. With the continuous and in-depth promotion of strategies such as industry 4.0 and made in China 2025, unmanned factories are close at hand
the mother of modern manufacturing industry is the mold, and the demand of society inevitably presents diversity. Therefore, changing the mold has become a stumbling block in front of the process of unmanned factories and the realization of unmanned. 3. It depends on the temperature. Whether the ambient temperature of the variable-frequency single column tensile testing machine is normal. It is required to be within the range of (1) 0 ℃ to 40 ℃, and it is better to be about 25 ℃; One of the primary problems to be solved by the factory. As an important branch of industrial manufacturing, plastic related industries naturally become an important force to improve the level of automation
before discussing the necessity of rapid mold change system of injection molding machine, let's first discuss the brief history of human development
brief history of human development
human beings come from the sea to the forest, come down from the tree and go to the land. On the land, we look up at the stars, and the future human history will inevitably go to space. Human beings need to reserve a lot of resources and knowledge before going into space. Knowledge comes from creative intelligence. Where does creative intelligence come from? Only by emancipating all mankind from the current tedious physical labor and emancipating our minds, can we develop creative intelligence. The ultimate problem of pushing mankind infinitely close to human philosophy is "where does it come from? Where does it go?"
the rapid development of Internet in the past few decades is for the high integration of intellectual resources. The future development of artificial intelligence is to prepare for the future grand computing power on the basis of the high integration of intellectual resources. At that time, the opportunity is ripe, artificial intelligence will go to outer space and become the future tool for the development of the universe, and mankind will eventually go to space and explore the universe
seems to be far fetched, but it's not. Now that we know the future, we know where manufacturing and technology will go. Therefore, unmanned factory is the inevitable result of technology and mission. This fundamentally explains the reasons and driving forces for the continuous development of science and technology, and explains why enterprises need to constantly update equipment to meet the needs of human development from a philosophical perspective. Whether the injection molding machine should be equipped with a rapid mold change system seems to be a problem that can no longer be discussed, but next, Mr. Xiong will still discuss the necessity of a rapid mold change system on the injection molding machine from the perspective of enterprise reality
modern manufacturing factory
1. The needs of enterprise standardization management
the rapid mold change system of injection molding machine can react to the standardization of enterprise production. Now many plastic products enterprises have different mold specifications. In particular, the inconsistency of templates will make a series of future automation and intelligence impossible to implement. First of all, the inconsistency of templates makes the intelligent mold library impossible to implement, and the inconsistency of templates makes the mold change vehicle impossible to implement. Unmanned chemical plants will eventually remain intelligent in words, and enterprises will eventually be submerged by the torrent of human development
2. The need for enterprises to reduce production costs
the rapid mold change system of injection molding machine helps enterprises reduce inventory, so as to achieve more flexible production management. Reducing inventory means reducing production costs, which includes the cost input of warehouse, packaging, raw materials, etc. the latter two points are easy to understand, focusing on the problem of storage costs, When many experts mention reducing storage costs, the first suggestion is to "reasonably set the upper limit of inventory". This problem seems simple, but it actually contains great things. What is reasonable? To set a reasonable or even lower the upper limit of enterprise inventory, the deliberation of data is naturally inseparable from the rapid switching function of the production site (that is, the rapid mold change system)
the rapid mold change system of injection molding machine helps enterprises reduce inventory, so as to achieve more flexible production management. Reducing inventory means reducing production costs, which includes the cost input of warehouse, packaging, raw materials, etc. the latter two points are easy to understand, focusing on the storage cost, including the following items:
warehouse site cost: if it is a rented warehouse, Generate rental expenses; If it is a self built warehouse, depreciation expenses will be incurred
expenses of warehouse equipment and miscellaneous consumables: reference equipment includes shelves, manual or automatic forklifts, etc., which are generally purchased as assets and included in depreciation expenses; Miscellaneous consumables, such as logistics trolleys, adhesive tape cartons and other cheaper or miscellaneous expenses consumed in each period, are included in the current miscellaneous consumables expenses
management personnel expenses: wages, benefits, etc. of warehouse management personnel
hydropower and power expenses: Hydropower and power expenses generated by the warehouse
when experts mention reducing storage costs, the first suggestion is to "reasonably set the upper limit of inventory". This problem seems simple, but it actually contains great things. What is reasonable? To set a reasonable or even lower the upper limit of enterprise inventory, the deliberation of data is naturally inseparable from the rapid switching function of the production site (that is, the rapid mold change system)
3. The need for enterprises to reduce labor costs
with the promotion of unmanned chemical plants, the pressure of enterprise competition is increasing day by day. Since 1988, the rapid mold change system of injection molding machine has helped reduce the dependence of enterprises on human resources, especially the difficulty of recruiting mold change workers, which is one of the pain points of the current industry, and the adoption of the rapid mold change system of injection molding machine has helped to change this situation. Put yourself in another position. As a worker, are you willing to work in a labor-saving factory or a factory that requires a lot of effort? At the same time, the use of rapid mold change system of injection molding machine can effectively reduce the number of mold change workers in the factory, thus directly reducing labor costs
about the rapid mold change system of injection molding machine, which type of work is the most helpful to the injection molding enterprise? It is the mold changing workers in the injection molding plant, but the rapid mold changing system of the injection molding machine is indeed embarrassing for the mold changing workers, because the use of qmcs · rapid mold changing system not only helps the mold changing workers reduce the operation intensity, but also may change the mold changing workers' lives
mold changers belong to technical types of work in the workshop, but most mold changers cannot adjust the machine, and the master who adjusts the machine can take over the job of replacing the mold worker after applying the rapid mold change system of the injection molding machine, so that the mold changers lose their original jobs
according to the calculation of a factory with 20 injection molding machines, there are two mold changers in a shift, and the whole factory needs four full-time mold changers and two machine changers at the same time. If the rapid mold change system of injection molding machines is adopted, combined with the waterway integration technology, the machine changers can be used to fully serve as the mold changers. Simply calculate the cost: the average monthly salary of four full-time mold changers is 6000 yuan, and the salary is 24000/month, which saves 288000 labor costs a year. The project cost of the rapid mold change system of 20 injection molding machines is about 800000. That is, from the perspective of labor cost alone, the project investment can be recovered within 3 years. If we calculate the production increase caused by the reduction of switching time, some high value-added products can achieve an investment return cycle of less than one year at the shortest time
4. The need for safe production of enterprises
this article should have been put in the first place. Without safety, the efficiency of production has no meaning and value. As we all know, in the process of replacing molds, almost all enterprises are full participation of workers. The more human participation, the greater the possibility of safety problems. Mold slippage caused by matching problems or tool problems during the hoisting process is easy to become a hidden danger of safety production. The rapid mold change system of injection molding machine combined with the one button mold change system fundamentally eliminates the possibility of unsafe accidents
the hydraulic quick mold change system of the injection molding machine does not need manual mold locking
5. The need for enterprises to improve production efficiency
taking the 180t injection molding machine as an example, it takes nearly 4 hours to replace a set of molds until the new product is officially produced. With the existing replacement method, it includes mold replacement, mold transportation, mold water temperature, oil temperature preheating and constant temperature to meet the requirements of formal production, The application of rapid mold change system of injection molding machine, mold waterway integration system and mold preheating platform can greatly reduce the mold change time to less than 10 minutes, so as to achieve 90% saving of the whole mold change time. The use of the rapid mold change system of injection molding machine alone can shorten the whole process from mold change to the production of new products by more than 50%. Because the time and product value corresponding to the customer's unit mold closing are different, it is impossible to calculate accurately, but we cannot forget the value of efficiency improvement to the enterprise
comparison of mold change time data
the above efficiency improvement table is obtained by fully combining the existing improvement reports of senior managers and networks of Japanese enterprises. Please correct any deviation from the actual situation
the rapid mold change system of injection molding machine can save the time of mold locking and tool finding! The use of integrated waterway system can save the time of plugging in the waterway! The use of mold preheating platform can save the time of mold preheating

comparison of mold change time in the application of rapid mold change system of injection molding machine
further improve the level of manufacturing technology and overall strength of injection molding machine before and after mold change time
entrepreneurs, do you think it is necessary to use the rapid mold change system of injection molding machine? Whether the hydraulic quick change mode system or the electric permanent magnet quick change mode system has become a different method to realize the development idea. After the successful completion of the project and the transformation of scientific and technological achievements,
in the actual customer contact process of Mr. Xiong, more and more orders are inclined to be delivered to factories with rapid mold change system, which means that there can be high reliability, efficiency and low inventory. Whether the mold changing workers are willing to join the enterprise and whether there is a rapid mold changing system has become the main factor they consider
the rapid mold change system of injection molding machine actually includes three parts: intelligent mold warehouse (mold storage), mold change trolley (mold transportation), and rapid mold locking system (mold installation). At present, enterprises in the stamping field have realized the real one key mold change, thus entering the ranks of unmanned factories in advance
entrepreneurs, do you think it is necessary to change the mold quickly? Whether it is the hydraulic rapid mode change system or the electric permanent magnet rapid mode change system, it has become a different way to realize the unmanned factory
