Problems solved by technology

[0002] During the production process of the mold, when there are deep ribs on the side of the product, the slider wraps the deep ribs. During the mold opening process, because the product is opened quickly, under the action of instantaneous tension, it is easy to Pull the product, or even pull it apart
As a result, the entire product is a scrap product after injection molding, which wastes manpower, wastes financial resources, and increases the cost of raw materials. In order to avoid straining the product, the mold opening process of the injection molding machine takes a long time to control, resulting in a very long injection molding cycle.

Abstract

The invention discloses a strain-preventing injection mould. The strain-preventing injection mould comprises a cavity insert and a core insert, an inclined guide pillar, a sliding block and a stop dog, wherein a cavity of a product to be processed is formed between the cavity insert and the core insert; the inclined guide pillar and the sliding block are positioned on one side of the cavity; the stop dog is arranged in the cavity insert, and the lower end of the stop dog is mutually contacted with the outer side surface of the product to be processed. According to the strain-preventing injection mould provided by the invention, the product has a deep rib position, the stop dog is arranged to effectively block the product, so that the product is prevented from straining; the strain-preventing injection mould provided by the invention has the characteristics that the installation is simple, the process is simple, the mould opening efficiency is high, and the production efficiency is improved. The structure of the strain-preventing injection mould provided by the invention is arranged in the inserts, and thus, the structure is suitable for a mould at which a thimble can not be arranged in a small sliding block.

Description

technical field [0001] The invention relates to an anti-strain injection mold. Background technique [0002] During the production process of the mold, when there are deep ribs on the side of the product, the slider wraps the deep ribs. During the mold opening process, because the product is opened quickly, under the action of instantaneous tension, it is easy to Pull the product, or even pull it apart. As a result, the entire product is a scrap product after injection molding, which wastes manpower, wastes financial resources, and increases raw material costs. In order to avoid straining the product, the mold opening process of the injection molding machine takes a long time to control, resulting in a very long injection molding cycle. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] In order to solve the above problems, the present invention proposes an anti-strain injectio...
