Injection mold allowing insert to be installed and dismantled quickly

Abstract

The invention relates to an injection mold allowing an insert to be installed and dismantled quickly. The injection mold comprises a main mold body, an inset structural member and positioning electromagnets, wherein the main mold body comprises a base material and a magnetic metal rib plate, the inset structural member comprises a base material and a magnetic metal rib plate, and each magnetic metal rib plate is wrapped in the corresponding base material; the main mold body is of an airtight cavity structure, the inset structural member is embedded in the main mold body and abuts against the inner surface of the main mold body, and at least two vacuum suckers are evenly distributed on each surface where the inset structural member makes contact with the main mold body; at least two positioning electromagnets are evenly distributed at the positions, corresponding to the positions where the inset structural member makes contact with the inner surface of the main mold body in an abutting mode, of the outer surface of the main mold body. According to the injection mold, on one hand, the structure of the mold can be adjusted flexibly according to parts to be machined, and on the other hand, during adjustment of the insert in the mold, installation and dismantling are convenient, installation position is flexible, positioning precision is high, and the defect that a connecting threaded hole needs to be formed for installation and positioning of the insert can be effectively avoided.

Description

technical field [0001] The invention relates to a mold for injection molding, in particular to an injection mold with inserts that can be quickly disassembled and assembled. Background technique [0002] At present, with more and more plastic material products, injection molding processing has developed rapidly. In order to meet the processing needs of various parts, it is often necessary to use injection molding machines to produce parts with the help of injection molds.

[0002] At present, with more and more plastic material products, injection molding processing has developed rapidly. In order to meet the processing needs of various parts, it is often necessary to use injection molding machines to produce parts with the help of injection molds. Due to the rapid change of the current product structure, product types However, the current injection molds are often fixed in structure and extremely poor in adjustment flexibility. Therefore, in order to meet the needs of parts production and processing, it is often necessary to equip injection molding equipment with a large number of injection molds. This method can most certainly meet the needs of production to a certain extent. , but the practice of equipping a large number of spare molds on the one hand increases the production cost of the product, on the other hand it also leads to insufficient utilization of mold resources, resulting in a large resource loss. In order to solve this problem, a flexible The invention mold for disassembling inlaid structural parts greatly improves the flexibility of mold application and improves the utilization rate of the mould. It is often necessary to connect with the mold body through bolts. On the one hand, the installation position of the mosaic structure is relatively fixed, and the disassembly efficiency is low. On the other hand, it also requires frequent setting of a large number of connection holes on the mold body, which seriously It destroys the structural strength and sealing performance of the main body of the mold, and greatly shortens the service life of the mold. Therefore, in view of this situation, it is urgent to develop an inventive injection mold to meet the needs of actual use
