In-mold assembly injection mold

Abstract

The invention provides an in-mold assembly injection mold. A movable mold plate is provided with a first mold core fixing part, a second mold core fixing part and a third mold core fixing part; a rotating mechanism is arranged on a movable mold, the rotating mechanism comprises a rotary table and a rotating driving assembly, the rotary table is driven to rotate to drive a second mold core moving part to switch positions between the second mold core fixing part and the third mold core fixing part and to drive a third mold core moving part to switch positions between the third mold core fixing part and the second mold core fixing part; the second mold core fixing part and the second mold core moving part or a third mold core moving part form a second mold core, and the third mold core fixingpart and the third mold core moving part or the second mold core moving part form a third mold core; a fixed mold is provided with a first cavity, a second cavity and a third cavity. According to thein-mold assembly injection mold, three workpieces can be injection-molded in the same set of mold at the same time, in-mold assembly is achieved in the mold, the production efficiency is improved, the movable mold does not need to rotate, the mold closing precision is guaranteed, and the molding quality is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold capable of in-mold assembly. Background technique [0002] Polymer materials are widely used in various fields such as medical treatment, transportation, and life. With the development of modern industry and science and technology, the processing and molding technology of polymers is also constantly maturing. In order to meet the diversified requirements of the polymer market for color, feel and material, the injection molding process has transitioned from a one-component to a multi-component process. Due to the advantages of high production efficiency and high added value of products, multi-component injection molding has gradually become an important part of the field of mold injection molding. [0003] In the current multi-component product molding process, for some special products, it is necessary to assemble the separately injection-molded product...

AI Technical Summary

Problems solved by technology

[0004] This multi-component product molding method in the prior art has the following disadvantages and deficiencies: 1. Manual assembly leads to low production efficiency, and the secondary assembly or reprocessing of separately formed parts will cause problems such as deformation and shrinkage of the product, As a result, a large scrap rate is generated; 2. For manually assembled products, the product quality cannot be guaranteed to be uniform

That is, each station is equipped with a mold, and each movable mold not only needs to be opened and closed with the injection molding machine, but also needs to be rotated. There are many movements of the movable mold, which will easily lead to poor precision after it is closed with the fixed mold, thus affecting the finished product. At the same time, the movable mold rotates in the state of no ejection, the mold positioning is unstable, and it is easy to cause inaccurate positioning, resulting in product out-of-tolerance and unstable mold structure
