In-mold multi-station injection molding machine

Abstract

The invention relates to an in-mold multi-station injection molding machine comprising a mold locking mechanism, an injection stage mechanism, and related driving and controlling mechanisms. A fixed plate and a moving plate are arranged on the mold locking mechanism. The fixed plate matches and is fixed with a fixed mold, and the moving plate matches and is fixed with a moving mold. A sub mold is arranged on the moving mold. The sub mold can perform relative movement on the moving mold through a sliding or rolling mechanism or other motion pair mechanisms. The relative movement of the sub mold is driven by a sub mold driving mechanism. The sub mold driving mechanism drives the sub mold, such that different station requirements are satisfied. Therefore, production processes such as in-mold assembling and multi-color multi-material injection are realized. According to the invention, some processes requiring secondary processing, especially movable parts, are executed in the mold. When a plastic product leaves the mold cavity, the product is already a finished product. Therefore, product assembling quality stability and fit compactness are improved, labor and material resources are saved, and factory spaces are saved.

Description

Technical field [0001] The invention relates to an in-mold multi-station injection molding machine, in particular to an injection molding machine capable of realizing an in-mold assembly process and multi-material or multi-color injection molding. Background technique [0002] Traditional injection molded parts that need to be assembled or have moving parts often require multiple or single injection molding machines and multiple sets of molds for single production, and then manual or mechanized assembly. Although with the development of technology, multi-material and multi-color injection molding machines can form multiple materials or multi-color injection molding at one time, it is still impossible to perform the processes of the active parts that require the second processing. This requires more equipment or manpower for secondary processing and assembly, which consumes manpower, material resources and workshop space, and increases investment costs. For the two-color or ...

AI Technical Summary

Problems solved by technology

Although with the development of technology, multi-material and multi-color injection molding machines can form multiple materials or multi-color injection molding at one time, it is still impossible to carry out the processes of the active parts that require the second processing.

This requires more equipment or manpower for secondary processing and assembly, which consumes manpower, material resources and workshop space, and increases investment costs.

For the two-color or multi-color machines on the market, they are all equipped with a turntable structure, which can only be used for injection molding of non-moving parts, which has great limitations.
