What norms should be observed in the production of plastic injection molds
In order to ensure that the production process of plastic products to meet the quality and accuracy requirements, while reducing production costs, improve production efficiency, the use of injection molds can be said to be very important operation, the production process is very critical and indispensable tools. Injection molds directly affect product quality and production efficiency, in order to ensure the reliability of mold accuracy, injection mold production process needs to follow the specification requirements.
First, material selection
In the injection mold production process, material selection is critical. Mold materials should have sufficient hardness and wear resistance to ensure long service life. Commonly used mold materials include high-quality tool steel and so on. The material of the mold should have good processing performance, in order to facilitate the manufacturing process of cutting, polishing and other process operations. In addition, for some special injection molds, such as transparent product molds, material selection should consider its transparency and high temperature performance.
Second, the design requirements
Injection mold design is the core link in the production process, good design to ensure that the mold has good molding performance and stable production efficiency. In the design process, according to the shape and size of the product to determine the type of mold structure, such as single-cavity mold, multi-cavity mold or set of molds. At the same time, the mold structure should be as simple as possible to reduce manufacturing costs and the probability of failure in the production process. Mould design needs to consider a reasonable cooling system and exhaust system to improve the molding effect and reduce the production cycle.
Third, processing technology
Injection mold production requires a series of processing technology, including CNC machining, EDM, polishing and so on. In the processing, the need to operate in strict accordance with the design requirements to ensure mold precision and surface quality. Conduct CNC machining using high-precision machine tools for parts processing, to ensure the geometric dimensional accuracy of the mold. For some complex shapes, it is necessary to use EDM for fine processing. Through polishing and other surface treatment processes to improve the surface finish and wear resistance of the mold. In order to ensure that the machining process meets the production requirements, choose mold cooperation to meet the standards of excellence in production.
Quality control
In the injection mold production process, quality control is to ensure the quality of the mold is a key link. Need to develop a detailed production process documents, clear requirements for each process and operating procedures. Secondly, for the mold processing, need to carry out strict testing and measurement, including size inspection, hardness testing. At the same time need to carry out mold assembly and debugging, to ensure that the mold in use, with stable performance and accurate size. Finally, after the completion of the mold production, the need for a full interview and finished product inspection to verify the molding effect and product quality.
V. Maintenance
Plastic injection mold in the process of use, the need for regular maintenance, to extend its service life and maintain a good working condition. First of all need to carry out mold cleaning work, including the removal of mold surface oil and residue, to prevent corrosion damage. Secondly, you need to lubricate the mold and rust treatment, using appropriate lubricants and rust inhibitors to ensure smooth operation of the mold moving parts. Another need to regularly check the mold parts, such as guide pillar, guide sleeve, etc., found that the problem of timely replacement and repair, to ensure the accuracy and stability of the mold.
Injection mold production specification requirements, to ensure the quality of the mold and production efficiency is critical. Through these normative requirements standards, can ensure that its performance advantages to reach a very good standard, especially with long-term reliable use advantages. During the production process, attention should be paid to the details of each link, and combined with the actual situation to adjust and improve to meet the needs of different product manufacturing.
