Injection mold with movement core insert stopping mechanism

Abstract

The invention discloses an injection mold with a movement core insert stopping mechanism, comprising a movable mold bearing plate, a movable mold plate, a fixed mold plate, a movable core insert and a binding block, wherein the fixed mold plate and the movable mold plate are arranged oppositely, and are matched to form a die cavity; the movable core insert is arranged in the die cavity; the movable mold bearing plate is positioned at the lower part of the movable mold plate, and is connected with the movable mold plate through screws which are equal in height; the binding block is fixed on the movable mold bearing plate, and the binding block penetrates through the movable mold plate; besides, a movement core insert stopping mechanism is arranged at one side of the upper surface of the movable mold plate; the movement core insert stopping mechanism comprises a driving device and a stopping guide rod; the driving device is fixed on the movable mold plate; the end face of the stopping guide rod connected with the driving device is provided with an inclined surface; and the inclined surface is matched with the inclined surface of the movable core insert. The injection mold in the invention uses the movement core insert stopping mechanism for guaranteeing the safety of the action of the mold, eliminating the gap between PL surfaces, improving the appearance and yield of the products, and covering the shortages of the inclined core-extracting way of the mold; and the injection mold has a wide application prospect.

Description

Technical field [0001] The invention relates to a mold, in particular to an injection mold with a moving mold core stopping mechanism, and belongs to the technical field of mold manufacturing. Background technique [0002] At present, many plastic products are processed by mold injection molding. In the injection molding process of some structurally more complex products, a good mold structure is mainly used to ensure the product yield and the safety of the mold itself. [0003] The production molds for the above-mentioned types of products usually adopt the structure method of oblique core pulling, but the disadvantage of this method is that the moving male mold core (oblique pulling large into the child) retreats due to excessive injection pressure, which causes the PL surface to not be tightly closed. , Thus forming burrs, affecting the appearance of the product, so we need to consider the design improvement of the mold itself to solve the above-mentioned problems. Summary of t...

[0003] The production molds for the above-mentioned types of products usually adopt the structural method of oblique core pulling, but the disadvantage of this method is that the moving male mold core (big oblique drawing) will retreat due to excessive injection pressure, which will cause the PL surface to not close tightly. , thus forming burrs and affecting the appearance of the product, so it is necessary to consider improving the design of the mold itself to solve the above problems
