A kind of buckle stripping mechanism and a kind of buckle stripping method

Abstract

The invention discloses an invertedly demoulding mechanism which comprises at least two first moving slide blocks and at least two second moving slide blocks, and further comprises a first moving shovel base, a second moving shovel base and a demoulding control device, wherein the first moving slide blocks and the second moving slide blocks are arranged alternately to form an inverted part; the first moving shovel base is arranged in the center of the inverted part, and is connected with the first moving slide blocks in a sliding manner through first clamping grooves; the included angle between the extending direction of each first clamping groove and the sliding direction of the first moving shovel base is a first inclined angle; the second moving shovel base is arranged in the center of the inverted part, and is connected with the second moving slide blocks in a sliding manner through second clamping grooves; the included angle between the extending direction of each second clamping groove and the sliding direction of the second moving shovel base is a second inclined angle; the demoulding control device is used for controlling the first moving slide blocks to move far away from an injection moulding piece. Correspondingly, the invention further discloses an invertedly demoulding method. As both the first moving slide blocks and the second moving slide blocks can be set with larger moving spaces, the inverting size is larger while the invertedly demoulding requirement of the injection moulding piece with a smaller internal space is met.

Description

technical field [0001] The invention relates to the field of injection molding product manufacturing, in particular to an undercut stripping mechanism and an underturn stripping method, which are used in the stripping process of injection molding products. Background technique [0002] In the injection molding process, an injection molded part with a full-circle inner undercut means that the inner wall of the injection molded part has a full-circle side convex or undercut. For the purpose of the mold, it is necessary to design a circular undercut stripping mechanism with a suitable core pulling mechanism. In the undercut demoulding mechanism, the undercut part of the mold is divided into four, six or more small sliders, and a shovel base is provided at the center of the undercut part, and the shovel base and each slider are connected by clamps. The grooves are slidingly connected, and the matching area between the adjacent sliders and the shovel base is made with different ...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual production process, the radial dimension of the undercut area of ​​some injection molded parts is relatively large, and the internal space is small at the same time, resulting in limited internal space in the center of the undercut part of the demoulding mechanism for accommodating the shovel base and the displacement of the slider , in this case, the leading slider can break away from the undercut area, but the backward slider is difficult to break away from the undercut. Therefore, the use of the above-mentioned circular undercut stripping mechanism cannot meet the stripping requirements of the undercut
