Anti-missing installation structure for insert molding

Abstract

The invention discloses an anti-missing installation structure for insert molding. The anti-missing installation structure comprises an induction device and an injection molding machine control system, wherein the induction device is fixedly installed on an injection molding male die, a trigger mechanism is arranged on the induction device, the trigger mechanism extends into a mold cavity of the injection molding male die, the trigger mechanism can be triggered by an insert which is put in the mold cavity of the injection molding male die, the induction device communicates with the injection molding machine control system, and an injection molding machine is controlled to start injection molding or stop injection molding by the injection molding machine control system. The anti-missing installation structure has the advantages of the simple structure and clever design, the insert is automatically induced by fully using the self structure of an insert injection mold, the condition of missing installation of the insert when the in-mold injection molding of the insert is performed is fully avoided, the rate of defective products and the safety in use are increased, the later manual inspection is not needed, a large amount of labor is saved, and the production cost of products is reduced.

Description

technical field [0001] The invention relates to an injection mould, in particular to an insert injection moulding preventing leakage structure. Background technique [0002] Many products have a structure in which metal parts, such as nuts, are embedded in plastic parts. These products are all injection-molded by injection molding. During injection molding production, it often happens that the inserts are missing. The injection molding machine There are no inserts in the injection-molded products, resulting in defective products. In the later stage, it takes a lot of time and energy to select. If there are products with missing inserts that are not picked out during the selection process, there will be risks during use. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects, the present invention provides an insert injection-prevention structure for preventing leakage, which can effectively prevent the leakage of inserts during in-mold injection...

Problems solved by technology

[0002] Many products have metal parts embedded in plastic parts, such as nuts, etc. These products are all molded by injection molding and in-mold injection molding. During injection molding production, inserts are often missed. There are no inserts in the injection molded products, resulting in defective products. It takes a lot of time and effort to select manually in the later stage. If there are products that lack inserts and are not picked out during the selection process, there will be risks in the use process.
