Plastic mold opening is a complex and fine process, from understanding customer needs to final mass production, every link is crucial. This article will introduce each link of plastic mold opening in detail to help you fully understand this process.
1. Understand customer needs
Everything starts from a deep understanding of customer needs. Communicate with customers in depth to clarify key information such as product function, appearance, size, material and expected output. This step is the basis for subsequent design and manufacturing to ensure that the mold can meet the actual needs of the customer.
2. Draw a picture
After understanding customer requirements, designers will draw product design drawings according to customer requirements. These drawings include detailed information such as 3D model of the product, dimensioning and material description. After the design drawing is completed, it will be reviewed and revised many times to ensure that it is correct before entering the next step.
3. Mold design
According to the product design drawing, the mold designer will design the mold structure. This includes determining the parting surface of the die, the pouring system, the cooling system, the jacking mechanism and other key parts. The mold design should not only meet the molding needs of the product, but also consider the manufacturing difficulty, cost and service life of the mold.
4. Mold embryo
The mold is the basic part of the mold, which carries the various parts of the mold. After the mold design is completed, it is necessary to select the appropriate mold embryo according to the design requirements. The choice of mold embryo should consider the size, shape, material and manufacturing accuracy of the mold.
5. CNC processing
CNC machining is a key link in mold manufacturing. Through the numerical control machine tool for mold parts accurate processing, to ensure that the size of each part of the mold accurate, accurate shape. CNC processing can not only improve the manufacturing accuracy of the mold, but also greatly shorten the manufacturing cycle.
6. Deep hole drilling processing
For some mold parts that need deep hole processing, such as cooling channels, deep hole drilling processing technology will be used. Deep hole drilling can ensure that the depth and diameter of the hole meet the design requirements, and ensure the smoothness and accuracy of the hole wall.
7. Wire cutting processing
Wire cutting is a kind of precision machining technology, which is mainly used to process mold parts with complex shapes and small structures. Machining with high precision and high surface quality can be achieved by cutting the workpiece with a thin metal wire under the action of an electric field.
8. EDM
EDM(electric spark machining) is a non-contact machining technology, mainly used for machining hard materials and complex shape mold parts. High precision and high surface quality machining can be achieved by removing the material through the electric spark discharge generated between the electrode and the workpiece.
9. Save mold polishing
Die polishing is one of the last processes in die manufacturing. By finely grinding and polishing the die parts, burrs and scratches generated during processing can be removed, and the surface quality and finish of the die can be improved. This is essential to improve the quality and appearance of molded products.
10. Mold assembly
After the tooling parts are processed, tooling assembly is required. Assemble and debug each part according to the design requirements to ensure that each part of the mold is closely cooperated and flexible in movement. After the mold assembly is completed, it is also necessary to conduct several trials and adjustments to ensure the stability and reliability of the mold.
11. Test the mold
Die testing is one of the key links in die manufacturing. By injecting plastic raw materials into the mold, the quality and appearance of the molded products are observed to meet the design requirements. Some problems may be found in the process of testing, such as size deviation, surface defects, etc., which need to be adjusted and improved in time.
12. Change the model
According to the test results and customer feedback, make necessary changes and improvements to the mold. This includes adjusting the size, shape, cooling system and other parts of the mold to improve the quality and production efficiency of the molded product. Maintain close communication with customers during the process of mold change to ensure that the modified mold can meet the needs of customers.
13. Mass production
After several testing and improvement, the mold finally reached the standard of mass production. At this point, the mold can be put into the production line for large-scale production. In the mass production process, it is necessary to pay close attention to the quality and production efficiency of the molded products, and adjust the production parameters and mold status in time to ensure the stability and reliability of the production process.
Plastic mold opening is a complex and fine process, involving multiple links and technologies. By strictly following the above process, we can ensure that the quality and performance of the mold meet customer needs, and lay a solid foundation for subsequent mass production.
