Five requirements for the quality of plastic mold steel

In the proper use of plastic mold steel, regular protection and maintenance of mold steel is also required. Protective protection of the die steel is planned, and after data processing in the protection process, to prevent problems that may occur in the production of the die steel, the efficiency of the repair operation is advanced.

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

Part planners should consider the technical requirements and structure of the parts to fit the manufacturability and feasibility of mold steel manufacturing.

⑵ Planning of mold steel

This is the most important step to advance the quality of mold steel. The demand takes into account many factors, including the selection of mold steel materials, the usability and safety of mold steel structure, the processability of mold steel parts and the convenience of mold steel repair At the beginning of planning, these should be considered as thoroughly as possible.

  • ① The selection of mold steel materials not only needs to satisfy the customer’s requirements for product quality, but also needs to consider the cost of the materials and their strength within a set period. The failure form and other factors to select materials.
  • ② When planning the mold steel structure, try to make the structure as compact and convenient as possible, and also ensure that the mold steel parts have sufficient strength and rigidity; when the mold steel structure allows, the corners of each appearance of the mold steel parts should be planned as round corners as possible, In order to prevent the stress from meeting; about the concave mold, cavity and part of the punch and core, the combination or mosaic structure can be used to eliminate the stress convergence. The elongated punch or core needs to select the appropriate protection method in the structure; The cold die should be equipped with equipment to prevent clogging of parts or waste (such as: ejector pins, compressed air, etc.). At the same time, we must also consider how to reduce the impact of sliding cooperation parts and repeated impact parts on the quality of mold steel caused by long-term wear.
  • ③ In the planning, it is necessary to reduce the plan that needs to be disassembled when repairing a certain part, especially when the wearing parts are replaced, as much as possible.

⑶ Manufacturing process of mold steel

This is also an important part of ensuring the quality of the mold steel. The processing methods and processing accuracy in the mold steel manufacturing process will also affect the service life of the mold steel. The accuracy of each part directly affects the overall equipment of the mold steel. In addition to the influence of the accuracy of the equipment itself, it is necessary to improve the processing methods of the parts. The technical level of the travel fitter in the process of grinding and matching the mold steel Processing accuracy; if the overall equipment of the mold steel fails to meet the requirements, the mold steel will be allowed to move in an abnormal state during the trial mode, which will have a great impact on the overall quality of the mold steel.
In order to ensure that the mold steel has excellent original accuracy-the original mold steel quality, we must first reasonably select high-precision processing methods during the manufacturing process, such as EDM, wire cutting, CNC machining, etc., and we should pay attention to the accuracy of the mold steel , Including the processing precision of mold steel parts, equipment precision and mold test inspection operations to summarize the precision of the mold steel, when viewing, you need to use high-precision measuring instruments as far as possible. Accurate measurement data cannot be reached with a common ruler or cursor card. At this time, precision measurement equipment such as a coordinate measuring instrument needs to be selected to ensure the accuracy of the measurement data.

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

In this way, the appearance wear resistance of the mold steel parts can be advanced, and then the quality of the mold steel can be better advanced.
Regarding the appearance strengthening, different strengthening methods should be selected according to the mold steel for different uses. In addition, a technology called FCVA vacuum diamond coating has been developed in recent years, which can form a layer on the surface of the part that is extremely robust and very lubricating, uniform and dense. This technology is particularly suitable for the appearance of mold steel Protective treatment is also a significant method for advancing the quality of die steel.

⑸ The correct use and protection of mold steel is also a major factor in the quality of traveling mold steel.

In recent years, the competition in the mold steel manufacturing industry in the world plan has become more and more fierce. Enterprises have been able to provide customers with personalized high-quality products with high efficiency and low consumption in the shortest possible time.
