Description

Aluminum Alloy Thin-wall Parts Mold with Quick Change Mold Core

technical field

The utility model relates to the field of moulds, in particular to an aluminum alloy thin-walled part mould, which can quickly replace the mold core.

Background technique

Injection molds are common and used molds in existing industrial production. With the development of technology, more and more products are being molded by injection molding. Using injection molds to mold plastic parts has also become a common method in production. Correspondingly, injection molds of various types and functions are required. The mold base is the main part of the injection mold, and the mold core forms the injection material into a plastic product with a complete structure and precise dimensions.

The current mold is generally a mold core corresponding to a mold base. Moreover, each mold core needs to be fixed in the mold base through the upper and lower molds. After processing a workpiece of one shape, if you want to process a workpiece of another shape, you need to disassemble the entire mold from the compression molding machine, and then Change to another mold corresponding to the workpiece. Because the cost of mold manufacturing is very high, the cost of such a workpiece corresponding to a mold is very high. Moreover, the disassembly and assembly process of replacing the entire mold is cumbersome, and the upper and lower molds, mold cores, and mold bases need to be disassembled separately, thereby directly reducing production efficiency.
