Multi-material in-mold assembling method

Abstract

The invention relates to a multi-material in-mold assembling method. The method comprises a movable mold, a sub-mold, a fixed mold and injection devices; a sub-mold positioning device, a sub-mold driving device and an ejection device are arranged on the movable mold; and a product assembling mechanism and an air blowing device are arranged on the fixed mold. Thedevice is characterized in that after the movable mold, the sub-mold and the fixed mold are assembled,the injection devices perform injection to the fixed mold, the molds are opened after the injection is completed, the movable mold drives the sub-mold to adapt to multi-station production requirements through the sub-mold driving device, then the sub-mold positioning is conducted through the sub-mold positioning device, then the molds are assembled, and products of different working procedures are assembled through the product assembling mechanism. The method and the device have the advantages that certain procedures needing secondary processing, especially movable parts are carried out in the mold, the plastic part is a final finished product when the plastic part leaves a mold cavity, the quality stability and the matchingtightness of the product assembly are improved, and manpower and material resources and workshop space are saved.

Description

technical field [0001] The invention relates to a multi-material in-mold assembly method, in particular to an in-mold assembly method for improving the production efficiency and quality of multi-material injection molding of an injection molding machine. 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. It is understo...

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.

It is understood that there is no mature in-mold assembly method implemented and promoted in the world, and some public in-mold assembly methods, such as patent application number 209910078083.5 "In-mold assembly method", need to set up the first master mold separately on the inside and outside of the injection machine Compared with the second female mold, the male mold can only be set between the first and second female molds, the structure is complex, and only single-station in-mold assembly can be performed, and multi-station multi-process assembly is not possible, which has great limitations
