Injection mold and injection molding machine thereof

Abstract

The invention provides an injection mold and an injection molding machine thereof. The injection mold comprises a cavity, a core and a core-pulling structure, and the core is arranged in the cavity toform an injection molding cavity; the core has a mold closing position close to the cavity, and a mold splitting position far away from the cavity; the core-pulling structure is in transmission connection with the core for driving the core to rotate in the circumferential direction of the core-pulling structure so as to switch between the mold closing position and the mold splitting position; andthrough supply of the injection mold, the problems that a square guide pillar 24 is slide in an inclined slot of a sliding block 21 and produces friction in the mold closing and splitting process ofan existing injection mold and an injection molding machine thereof, and consequently powder is generated and contaminates the products easily are solved.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold and an injection molding machine thereof. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. The plastic that is melted by heat is injected into the mold from the nozzle under high pressure, and after cooling and solidification, a molded product is obtained. [0003] At present, the slider cavity in the prior art is composed of a set of oppositely arranged sliding movable blocks. The above-mentioned sliding movable blocks are arranged on the lower mold. On the upper mold, during the mold clamping and parting process, the square guide column will move up and down in the vertical direction. During the movement, the square guide column will slide in the inclined slot of the sliding movable block, thereby pushing the sliding movable block ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved in the present invention is to solve the problem that the square guide post 24 and the sliding movement of the existing injection molds will not Can rub each other between block 21, thus produce friction powder, pollute the problem of the product that injection mold is manufactured; Therefore, the present invention provides a kind of injection mold, comprises: a kind of injection mold, comprises: mold cavity; Core, Accommodated in the cavity to form an injection molding cavity, the core has a mold closing position close to the cavity and a parting position away from each other; the core pulling structure is connected with the core drive to driving the core to rotate in its circumferential direction, thereby switching between the closed position and the parted position
