Abstract

The invention relates to a hollow injection molding method. A movable plate, a movable mold, a sub-mold driving device, a sub-mold, a fixed plate, a fixed mold and an injection mechanism are involvedin the method. The method is characterized in that the movable mold, the sub-mold, and the fixed mold are closed, then an injection molding machine performs injection operation, after the injection iscompleted, mold opening is carried out until a required distance is achieved, the movable mold drives the sub-mold to be matched with the next station through the sub-mold driving device, then the mold closing action is carried out again, original separated part products are spliced together, then secondary injection is carried out, and the separated different products are injected together through plastics to complete hollow injection molding products. According to the method, certain procedures needing secondary processing, especially the hollow products which are provided with seals and need to be welded, are designed to be carried out in the molds, and the hollow plastic parts with the seal are the final finished products when leaving mold cavities, so that the product assembly quality stability and the fit tightness are improved, and the manpower and material resources and the workshop space are saved.

Description

technical field

[0001] The invention relates to a hollow injection molding method, in particular to a hollow injection molding method with a seal for improving the production efficiency and quality of injection molding of an injection molding machine. Background technique

[0002] Traditionally, blow molding is often used when hollow-molded plastic parts are required, or multiple or single injection molding machines and multiple sets of molds are produced in a single way, and then manually or mechanized assembly is performed for secondary injection molding, but blow molding has certain limitations. Sex, can not achieve hollow sealing performance at one time. Although with the development of technology, multi-material and multi-color injection molding machines have appeared, which can form multiple materials or multi-color injection molding at one time, it is still impossible to perform those hollow sealed injection molded parts that require secondary processing, which requir...
