Injection mold capable of preventing product from being damaged under pulling

Abstract

The invention discloses an injection mold capable of preventing a product from being damaged under pulling. The injection mold comprises an upper mold plate and a lower mold plate, wherein a left oblique guide pillar is arranged on the left portion of the upper mold plate, and a right oblique guide pillar is arranged on the right portion of the upper mold plate; a left shovel base, a left sliding block and a left top plate are arranged on the left portion of the lower mold plate, and a right shovel base, a right positioning block, a right sliding block and a right top plate are arranged on the right portion of the lower mold plate; the left oblique guide pillar penetrates through the left sliding block, and the right oblique guide pillar penetrates through the right sliding block; the left shovel base is in wedging fit with the left sliding block through a wedge-shaped surface, and the right shovel base is in wedging fit with the right positioning block through a wedge-shaped surface; a first centre and a second centre are arranged on the left portion of the lower mold plate, and a third centre and a fourth centre are arranged on the right portion of the lower mold plate; the tail end of the second centre abuts against the left side of the product in an injection cavity, and the tail end of the fourth centre abuts against the right side of the product in the injection cavity. By the adoption of the injection mold, the problem of the prior art that a product is stuck to sliding blocks easily is solved, product quality is improved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a mold, in particular to an injection mold which can prevent products from being scratched. Background technique [0002] When using injection molds to produce plastic products, sliders are generally used for side core pulling. However, the glue and ribs of many products are relatively deep. After the mold is opened, the product has not come out of the slider, and the product is easy to stick to the slider. If the product is not on the block, it is difficult to take out the product. Even if it can be taken out, the product will be strained because it is not separated from the slider in time, which will increase the rate of defective products and increase the production cost. Moreover, the difficulty of taking out the product will also affect the molding cycle and production efficiency, and waste resources. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention i...
