AI Technical Summary

Technical Problem

The existing injection molds have draft inclination problems during right-angle product forming process, which leads to indentation and warping at the edges and corners, affects product quality, and lacks the function of adjusting the draft angle, which limits the application scope and automation effect of the device.

Method used

An injection mold including a box, a driving mechanism, a hydraulic rod and an auxiliary mold release mechanism is designed. Through the cooperation of the movable rod and the fixed block, the extension and angle adjustment of the mold body are realized; through the cooperation of the support rod and the return spring, the auxiliary mold release mechanism realizes auxiliary mold release of the injection molded parts that are adhered to the inner wall of the upper mold seat.

Benefits of technology

The function of small-angle molding is realized, which increases the compatibility and scope of application of the device, facilitates the mold release of injection molded parts, improves production efficiency and automation effects, and avoids the problems of sticking and falling damage of injection molded parts.

Abstract

The utility model discloses an injection mold capable of realizing small-angle mold drawing, and relates to the technical field of injection molds. The injection mold capable of achieving small-angle mold pulling comprises a box body, a driving mechanism is installed at the top of the box body in an embedded mode, a hydraulic rod is fixedly installed at the top of the box body through an installation frame, an upper mold base is fixedly installed at the output end of the hydraulic rod, and two sets of auxiliary demolding mechanisms are fixedly installed on the two sides of the top of the upper mold base; the driving mechanism comprises a lower die base, and a shell is fixedly installed in the center of the interior of the lower die base. An operator manually pushes a movable rod to move vertically, and the movable rod moving vertically can drive a fixed block to synchronously move to one side of an abutting block for abutting, so that the abutting block drives a mold body to extend out of a shell; and by changing the moving position of the die body, an operator can conveniently carry out die drawing operation on materials in the lower die base, and the function of adjusting the die drawing angle is achieved.
