Core Pulling Guide Slide Mechanism for Injection Mold

Abstract

The invention relates to a core pulling guide sliding mechanism of an injection mold. The core pulling guide sliding mechanism comprises a sliding block, two core pulling sliding blocks and a moving die insert fixed to a moving die. The top face of the moving die insert is an isosceles triangle, and the bottom face of the moving die insert is an isosceles trapezoid. Insert guide sliding grooves are formed in the inclined faces on the two sides of the moving die insert. Each core pulling sliding block is similar to a triangular prism. Insert guide sliding blocks are fixed to one side face of each core pulling sliding block. An insert guide sliding plate is arranged on each insert guide sliding block, and the structures of the insert guide sliding plates cooperate with those of the insert guide sliding grooves. Sliding block guide sliding grooves are formed in the other side face of each insert guide sliding block. Two sliding block inclined faces are arranged on the end face, close tothe moving die insert, of the sliding block. The sliding block inclined faces cooperate with the side faces, with the sliding block guide sliding grooves, of the core pulling sliding blocks. Sliding block guide sliding blocks are fixedly mounted on the two sliding block inclined faces, and sliding block guide sliding plates cooperating with the sliding block guide sliding grooves are arranged on the sliding block guide sliding blocks. By means of the core pulling mechanism, core pulling of different directions can be achieved, and especially core pulling can be achieved when the core pulling directions intersect and interfere with one another.

Description

[0001] This invention is a divisional application of the invention patent application with application number 2017113860866, application date is December 20, 2017, and the invention name is "Single-slider multi-directional core-pulling mechanism for injection mold". technical field [0002] The invention relates to the technical field of injection molds, in particular to a core-pulling and sliding guide mechanism for injection molds. Background technique [0003] The core-pulling mechanism is one of the most common mechanisms in injection molds, and is generally designed at the undercut position of the product. At present, the commonly used core-pulling mechanism is that the inclined guide column drives the core-pulling slider to perform core-pulling, that is, when the movable and fixed mold is opened, the inclined guide column drives the core-pulling slider to move, so that the core is separated from the product to facilitate product demoulding. However, the conventional in...

Problems solved by technology

However, the conventional inclined guide column drives the core-pulling slider to move in only one direction. When there are longitudinal and multiple directions of core-pulling in a small space, especially when the core-pulling directions interfere with each other, the conventional slider core-pulling scheme will no longer apply
