Single-cavity molding and secondary seal-off mechanism of injection mold

Abstract

The invention relates to the technical field of injection molds, and discloses a single-cavity molding and secondary seal-off mechanism of an injection mold. The single-cavity molding and secondary seal-off mechanism of the injection mold comprises a fixed half and a moving half, wherein a baseboard is fixedly connected with the bottom of the fixed half, the moving half and the fixed half are arranged in an attached mode, a die cavity is formed after the moving half and the fixed half are closed, a ring cavity is formed in the fixed half, a partition board groove communicates with the top of the ring cavity, and is formed in the top of the ring cavity, the partition board groove communicates with the die cavity, a partition board which matches the interior of the partition board groove isslidingly connected with the interior of the partition board groove, the top end of the partition board is flush with a top groove opening of the partition board groove, a ring block which matches theinterior of the ring cavity is fixedly connected with the interior of the ring cavity, a threaded sleeve is rotatably connected with a center of the ring block through a first bearing, a threaded rodwhich matches the threaded sleeve is fixedly connected with the bottom end of the partition board, and the threaded rod penetrates through the threaded sleeve, and extends downwards. By means of thesingle-cavity molding and secondary seal-off mechanism of the injection mold, single-die-cavity double-color injection molding can be conducted through the injection mold, so that the structure of theinjection mold is greatly simplified, and the injection molding cost is greatly reduced.

Description

Technical field[0001]The invention relates to the technical field of injection molds, in particular to a single cavity molding secondary sealing mechanism of an injection mold.Background technique[0002]In order to change the lack of beauty of a single color, plastic products usually use two-color injection to improve their aesthetics. The current two-color mold is a product that requires two molds or two independent cavities in a mold. This plastic product is molded The process requires the injection molding machine to be equipped with rotary injection molding equipment, which has a complicated structure and high cost.Summary of the invention[0003](1) Technical problems solved[0004]Aiming at the shortcomings of the prior art, the present invention provides a single-cavity molding secondary sealing mechanism, which has the advantages of single-cavity two-color injection molding, and solves the problems of complex structure and high cost of the two-color mold in the prior art.[0005](2...
