Why does mold assembly encounter the problem of reading assembly drawings

A mold with a qualified assembly is not the same as a qualified mold. Strictly speaking, after a period of trial production to assess the rationality, correctness and reliability of the product's molding process and mold structure, no problems with the accuracy and quality of the product are found, and it can be called a truly qualified mold.

The content of mold assembly includes selection of assembly standards, component assembly, adjustment, repair, final assembly, grinding and crate injection mould polishing, and inspection. Obviously, mold assembly is a stage of the manufacturing process that directly verifies the rationality of mold structure design and ensures mold performance.

According to the technical requirements and structural characteristics of mold design, assembly and final assembly are carried out in accordance with the assembly process sequence and process regulations. Then carry out mold dry running test, inspection, adjustment, and finally mold trial, trimming and confirmation. Obviously, the mold assembly process is the most critical manufacturing process to form the mold manufacturing accuracy, quality and performance, which must be strictly controlled and managed.

In the design of parts, mold structure and assembly, and technical exchanges, the problem of reading assembly drawings will be encountered. The purpose of reading the mold assembly drawing is to understand the mold structure, component performance, working principle, function, and assembly relationship. The method of reading the drawing is flexible and the steps can be different, but you must know in advance what are the customary drawing methods of the assembly drawing of the injection mold, and pay attention to three common problems, namely the positioning relationship between the parts, pouring, ejecting, and core pulling The dynamic and static relationship of the system and the occlusion relationship between the internal and external levels of each system structure.
