Detector for injection mold

Abstract

The invention relates to the related technical field of injection molding, and discloses a detector for an injection mold, the detector comprises a female mold and a male mold, one side of the male mold is provided with a detection body, one side of the detection body is provided with a fixing body, the fixing body is connected with an injection molding machine, and a molding cavity is formed between the female mold and the male mold. Detection holes are formed in the side, close to the forming cavity, of the detection body, the detection holes are distributed around the forming cavity, by arranging the detection holes, a detection sliding block, an exhaust groove, an exhaust pipe, a temperature control groove and the like, fluid in the forming cavity is increased, and when the fluid at a certain position pushes the detection sliding block to slide for a certain distance in the detection hole, the detection sliding block is pushed to slide for a certain distance; the distance sensor senses the moving distance of the detection sliding block, and when the detection sliding block moves, it is considered that gas is completely exhausted at the position, and the position is filled with liquid.

Description

technical field [0001] The invention relates to the technical field related to injection molding, in particular to a detector for injection molds. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding machine is the main molding equipment that uses plastic molding molds to make thermoplastic or thermosetting materials into plastic products of various shapes. Injection molding is It is realized by injection molding machine and mold. The disadvantages of injection molding include insufficient injection of the product and bubbles around the product. The methods to overcome the above problems include heating the molding cavity, increasing the injection time, and enhancing exhaust. However, these adjustment methods Usually it needs to be adjusted through repeated experiments, and the appropriate parameters have been reached to make the product rea...

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding machine is the main molding equipment that uses plastic molding molds to make thermoplastic or thermosetting materials into plastic products of various shapes. Injection molding is It is realized by injection molding machine and mold. The disadvantages of injection molding include insufficient injection of the product and bubbles around the product. The methods to overcome the above problems include heating the molding cavity, increasing the injection time, and enhancing exhaust. However, these adjustment methods Usually it needs to be adjusted through repeated experiments, and the appropriate parameters have been reached to make the product reach the qualified state. The main problem to be solved by the present invention is how to detect the plastic filling state inside the molding cavity of the mold, provide direct data for debugging, and improve the debugging of injection molds. efficiency
