Embodiment 1

[0032] Such as figure 1 , Image 6 In the shown embodiment 1, an injection mold slider drives the core-pulling release mechanism, which includes an upper double plate and a lower double plate. A cavity is connected under the upper double plate, and a hot runner is connected to the lower double plate. Plate, set the hot runner fixing plate on the hot runner plate, connect the square iron on the hot runner fixing plate, set the core 1 on the square iron, set the thimble plate between the core and the square iron, and set it in the core There are core inserts 2. A slider-driven core-pulling and undercut mechanism for an injection mold also includes a core-pulling and undercut assembly, which includes a slider core-pulling assembly disposed in the core insert 2 and a core-pulling assembly disposed on the core The core-pulling drive assembly is used to drive the slider core-pulling assembly to move.

[0033] Such as figure 2 As shown, the slider core-pulling assembly includes ...

Abstract

The invention discloses a sliding block driven core pulling and inverted buckle removing mechanism for an injection mold. The mechanism comprises a mold core, a mold cavity and a core pulling and inverted buckle removing assembly, a mold core insert is arranged in the mold core, and the core pulling and inverted buckle removing assembly comprises a sliding block core-pulling assembly fixed on the mold core insert and a core-pulling driving assembly arranged on the mold core. According to the mechanism, the side surface core pulling of a product is realized, and the inconvenience in core pulling caused by interference is avoided; and the mold manufacturing cost is reduced and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold slider-driven core-pulling release mechanism. Background technique [0002] Injection molding is an important means of product forming. Injection molding is the process of making various plastic materials into products that people need by using the principle that plastic materials change shape under high temperature and high pressure. At present, due to assembly problems of some plastic products, when the mounting holes on the side are close together, if the traditional design is directly used for inclined top or slider, interference is likely to occur and core pulling cannot be completed normally. [0003] For example, the "improved structure of an injection mold core-pulling mechanism" disclosed in the Chinese patent literature, its announcement number CN204566579U, includes a movable mold base, a movable mold plate, a fixed mold base and a fixed mold ...
