Bidirectional side core-pulling mechanism of mold

Abstract

The invention discloses a bidirectional side core-pulling mechanism of a mold. The bidirectional side core-pulling mechanism comprises a movable mold plate, wherein a side core-pulling sliding block part is arranged on the movable mold plate and comprises a sliding block, a fixed side mold core and a movable side mold core; a sliding groove is formed in the movable mold plate; the sliding block can slide in the sliding groove; the fixed side mold core is fixedly arranged on the sliding block; the movable side mold core is connected with the fixed side mold core through a dovetail groove; the matching surfaces of the movable side mold core and the fixed side mold core are inclined surfaces; a non-forming end boss and a forming end boss are arranged on the movable side mold core on one sidefar away from the fixed side mold core; a guide limiting plate is fixed on the movable mold plate; a limiting groove is formed in the guide limiting plate; the movable length of the non-forming end boss in the limiting groove is the side core-pulling length of the movable side mold core; a long groove is formed in the movable side mold core; and a limiting pin extending into the long groove is fixedly arranged on the fixed side mold core. The bidirectional side core-pulling mechanism is simple in structure, low in manufacturing cost and high in stability, and bidirectional side core-pulling forming and resetting can be realized in one-time mold opening.

Description

technical field [0001] The invention relates to a mold, in particular to a side core-pulling mechanism of the mold, which belongs to the technical field of molds. Background technique [0002] With the increasing application of plastic products, the structure of plastic parts is becoming more and more complex. Many plastic parts are required for installation or assembly, such as figure 1 As shown, there are side convex-concave structures perpendicular to each other in the same position, which is prone to interference in mold design, and it is difficult to achieve simultaneous core-pulling molding. Contents of the invention [0003] The purpose of the present invention is to propose a mechanism with low cost, simple structure and capable of simultaneously realizing two-way side core pulling. [0004] To achieve the above object, the present invention takes the following technical solutions: [0005] A two-way side core-pulling mechanism for a mould, comprising a movable t...
