In the correct use of plastic injection mold steel, it is also necessary to regularly protect and maintain the mold steel. The protective protection of the mold steel is planned, and the data processing in the protection process is carried out to prevent the problems that may occur in the production of the injection molding tooling steel, and the efficiency of the repair operation.


Plastic Injection Mold Maintenance & Care - How To Maintain Injection Moulding


⑴ The planning of the parts should be reasonable, and the best structural plan should be selected as much as possible.

The planner of the part must take into account that the technical requirements and structure of the part must be compatible with the manufacturability and feasibility of mold steel manufacturing.


⑵ Planning of mold steel

This is the most important step in the quality of mold steel. Many factors need to be considered, including the selection of mold steel materials, the availability and safety of mold steel structure, the workability of mold steel parts, and the convenience of mold steel repair. , These should be considered as thorough as possible at the beginning of planning.

① The selection of injection molding tooling steel materials must not only satisfy the customer's requirements for product quality, but also consider the cost of the materials and their strength within the set period. Of course, it must also be based on the type of mold steel, operating methods, and processing speeds. , The primary failure form and other factors to select materials.

② When planning the mold steel structure, try to be as compact as possible and easy to operate, and ensure that the mold steel parts have sufficient strength and rigidity; when the mold steel structure allows, the corners of the mold steel parts should be planned as rounded transitions as much as possible. In order to prevent stress convergence; for the concave mold, cavity and part of the punch and core, a combination or inlay structure can be used to eliminate stress convergence. For the slender punch or core, appropriate protection methods must be selected in the structure; about Cold punching dies should be equipped with equipment (such as ejector pins, compressed air, etc.) to prevent clogging of parts or waste materials. At the same time, it is also necessary to consider how to reduce the impact on the quality of mold steel caused by the wear of sliding parts and repeated impact parts during long-term use.

③ In the planning, it is necessary to reduce the planning of disassembly and assembly when repairing a certain part, especially when the wearing parts are replaced, reduce the disassembly and assembly plan as much as possible.


⑶ Manufacturing process of mold steel

This is also an important part of ensuring the quality of mold steel. The processing methods and machining accuracy in the mold steel manufacturing process will also affect the service life of the mold steel. The accuracy of each component directly affects the overall equipment of the mold steel. In addition to the accuracy of the equipment itself, it is necessary to improve the processing methods of the parts, and the technical level of the traveling fitter in the mold steel grinding and matching process to advance the mold steel parts. Processing accuracy; if the overall equipment of the mold steel does not meet the requirements, the probability of the mold steel moving in an abnormal state during the test mold will have a great impact on the overall quality of the mold steel.

In order to ensure that the mold steel has excellent original precision—the quality of the original mold steel, the high-precision processing methods must be selected reasonably during the manufacturing process, such as electric discharge, wire cutting, CNC machining, etc., and attention should be paid to the accuracy of the mold steel. , Including the machining accuracy of mold steel parts, equipment accuracy, and the accuracy of mold steels summarized by mold test inspection operations. High-precision measuring instruments should be selected as much as possible when checking. Regarding those mold steel parts with messy surface and surface structure, if The accurate measurement data cannot be reached with ordinary rulers and vernier cards. At this time, precise measurement equipment such as a three-coordinate measuring instrument must be selected to ensure the accuracy of the measurement data.


⑷ Strengthen the appearance of the main forming parts of the mold steel

In this way, the surface wear resistance of mold steel parts can be improved, and then the quality of mold steel can be improved.

Regarding the appearance strengthening, different strengthening methods should be selected according to the mold steel used for different purposes. In addition, a technology called FCVA vacuum diamond coating developed in recent years can form a very strong and very lubricating, uniform and dense protective film on the surface of the part. This technology is particularly suitable for the surface of mold steel. Protective treatment is also a significant way to improve the quality of mold steel.


⑸ The correct use and protection of plastic injection mold steel is also a major element of the quality of marching mold steel.

In recent years, the competition in the mold steel manufacturing industry in the world plan has become more and more fierce. The plastic injection mold company has the ability to provide customers with personalized and high-quality products in the shortest possible time with high efficiency and low consumption. It has become a sign of the company's ability to compete.
