Mold with sliding block and ejector pin

Abstract

The invention relates to a mold with a sliding block and an ejector pin. The mold comprises the sliding block, a spring, the ejector pin, a sliding locking block, a fixing block used for fixing the ejector pin and an abrasion resistant plate which is abutted to the sliding locking block, wherein the ejector pin is arranged in the center of the spring; one end of the ejector pin penetrates through the sliding block and is abutted to a product to be processed; the other end of the ejector pin is abutted to the sliding locking block; a mortise is formed in the abrasion resistant plate; a draw pin which is matched with the abrasion resistant plate is arranged on the fixing block, penetrates through the mortise and is abutted to the sliding locking block; and a straight surface groove is formed in the abutting part of the sliding locking block and the draw pin. According to the mold, with connection of the ejector pin and the fixing block, the length of the ejector pin is shortened, and the anti-deformation ability of the ejector pin is improved; and through a mortise and tenon structure between the fixing block and the abrasion resistant plate, the stability of the structure of the ejector pin is improved, and thus the service life of the ejector pin is prolonged. The mold is reasonable in design and is suitable for large-scale popularization.

Description

technical field [0001] The invention designs a mold, in particular relates to a mold with a sliding block thimble. Background technique [0002] During the production process of the mold, when there are deep ribs on the side of the product to be processed, the slider wraps the deep ribs during the mold opening process. Because of its fast mold opening, it will generate tension on the product in an instant. In the process, it is easy to strain the product, so that it is pulled 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] In view of the present situation of the prior art above, the technical problem to be solved by the present invention is to ...
