A molding die for an injection molded part with an insert

Abstract

The invention discloses a forming mold of an injection molding part with an insert. The forming mold comprises a first template, a second template and a third template; the first template and the second template are detachably connected; the second template and the third template are slidingly matched and connected; a first forming part is arranged on the first template; the second template is provided with a second forming part and an insert hole; the second forming part and the first forming part correspondingly form an injection forming cavity; the insert hole corresponds to the injection forming cavity; and an ejection rod is arranged on the third template, and corresponds to the insert hole. Through cooperation of the first template, the second template and the third template, the formation of plastic parts with inserts can be realized without using external auxiliary loading equipment, so that the injection molding period is short, and the insert falling problem dose not occur inthe injection molding process.

Description

technical field [0001] The invention relates to the field of injection molding, and more particularly, relates to a molding die for injection molded parts with inserts. Background technique [0002] Injection molding with inserts refers to the method of pre-loading inserts of different materials in the mold and injecting resin, so that the molten resin material and inserts are bonded and solidified to form injection molded parts. With the wide demand for injection molded parts, people have put forward higher and higher requirements for injection molded parts with inserts. Especially in order to meet the needs of assembly of electronic components, many parts of components are injection molded parts, and these parts are provided with inserts such as metal nuts. [0003] The existing injection molded parts with inserts are loaded into the mold through auxiliary feeding equipment such as manual or manipulators. This injection molding process with inserts needs to be implemented...

AI Technical Summary

Problems solved by technology

[0003] The existing injection molded parts with inserts are loaded into the mold through auxiliary feeding equipment such as manual or manipulators. This injection molding process with inserts needs to be implemented with the help of external auxiliary feeding equipment. The injection molding cycle is long, and the inserts are easy to fall off during the injection molding process, which leads to the problem of compression molding
