How to improve the quality of the casting molds?

Precision casting mold structure design, it is necessary to try to let the structure is very compact, very easy to operate, but also to ensure that the mold parts have sufficient strength and stiffness; in mold structure allows the case, the mold parts surfacethe corner we should as much as possible to design into a rounded transition, in order to avoid stress concentration; able to adopt a combination of the die cavity and some punch, core, or mosaic structure to eliminate the stress concentration, slender convexmold or core structure, you need to take appropriate protective measures; die, the necessary configuration to prevent parts or waste clogging the device (such as: the spring-loaded pin, compressed air). The same time, we must consider how to reduce sliding fitting and frequently hit pieces to wear in the long-term use in mold quality.
Proper use and maintenance of precision casting molds, is also a major factor in the quality of the mold can improve. As: installation and commissioning of the mold way must be very appropriate in the case of hot runner, power wiring must be correct, the cooling channels to try to meet the design requirements in production, mold injection molding machines, die casting machines, presses parameters need and design requirements consistent. The proper use of the mold, the mold also need regular maintenance, mold guide post, guide sleeve and the other with the relative movement of the parts must often filling oil, for forging dies, plastic mold, die casting mold like mold before each molded to be the lubricant or from the mold agent sprayed on the surface of the formed parts. Mold preventive maintenance plan, but also through the maintenance of data processing, will be able to prevent mold problems that may arise in the production, but also can improve the efficiency of maintenance work.
