Automatic system for IML injection molding

Abstract

The invention discloses an automatic system for IML injection molding. The automatic system comprises a sheet storage mechanism, a sheet transfer mechanism and an orifice cutting seat, wherein the sheet storage mechanism comprises a sheet storage and taking seat for storage of a stack of film sheets, a sheet storage and placement seat for placement of the single film sheet and a sheet suction seat for sucking away the film sheets in the sheet storage and taking seat and placing the film sheets in the sheet storage and placement seat; the sheet transfer mechanism comprises a sheet transfer seat for sucking the film sheets in the sheet storage and taking seat, placing the film sheets in an injection mold, and sucking IML decorating parts in the injection mold out of the injection mold; the orifice cutting seat comprises a positioning placement groove for placement of the IML decorating parts, blades used for cutting off orifices of the IML decorating parts, and a waste conveying channel. Compared with the prior art, the automatic system has the advantages as follows: full-automatic consecutive operation is adopted, and unmanned production is achieved, so that the whole working efficiency is improved greatly, the advantages of precision in taking out and high safety system are achieved, that the cutting surfaces of the IML decorating parts are relatively smooth is ensured, and appearance quality is not influenced.

Description

technical field [0001] The invention relates to an auxiliary mechanism for in-mold injection molding, in particular to an automatic system for transferring sheets and IML injection molding parts in the IML injection molding process. Background technique [0002] In-mold insert injection molding is a new technology integrating decoration and injection molding that is popular at home and abroad in recent years. , Put the diaphragm into the injection mold for injection, so that the surface of the printed pattern diaphragm is integrated with the plastic. After the injection molding is completed, the injection molded part is taken out of the injection mold. The plastic block (that is, the glue port), and finally cut off the glue port to obtain the final product, that is, the IML decorative part. This in-mold injection molding process is widely used in the production of mobile phone back covers, home appliance covers and notebook casings, etc. Especially in the production proces...

AI Technical Summary

Problems solved by technology

Especially in the production process of the back cover of the mobile phone, workers need to take out a piece of film from a pile of film sheets, and then place the taken out film sheet in the injection mold for the back cover of the mobile phone. After injection, the worker takes it out from the injection mold. IML decorative parts, after taking it out, manually cut off the glue joint. This series of manual operation methods, on the one hand, increase work efficiency, and when workers take out one of the film sheets from a pile of film sheets, they often fail because the film sheet is too thin. Two or more film sheets will be taken out at the same time, making the taking out of the sheets less accurate, and causing problems with burrs on the cut surface of the rubber mouth; on the other hand, there will be problems when workers pick and place objects in the injection mold. Injection molds cause safety hazards to workers’ hands due to misoperation by others, and the safety system is low
