Abstract

The invention provides a spoiler support die secondary ejection core pulling structure. An ejector pin panel, an ejector pin bottom plate and a core pulling mechanism are included. The core pulling mechanism comprises a straight ejector block and further comprises a first inclined loose core and a second inclined loose core which penetrate through the straight ejector block. The first inclined loose core is arranged on a rear die through an installing base in a sliding manner. The end portion of the second inclined loose core is fixedly connected with a connecting block. The connecting block is arranged on the rear die through a limiting block in a sliding manner. A first elastic element is arranged between the connecting block and the straight ejector block. The ejector pin panel and theejector pin bottom plate are arranged on the lower side of the rear die. The ejector pin panel is provided with an ejector pin, the ejector pin bottom plate is provided with an ejector rod for jackingthe straight ejector block, and each of the ejector pin panel and the ejector pin bottom plate is provided with a linkage mechanism matched with the core pulling mechanism. The provided spoiler support die secondary ejection core pulling structure overcomes the defects that an existing demoulding structure is not suitable for products with complex structures, demoulding is difficult, and the demoulding quality is poor.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a secondary ejection core-pulling structure of a spoiler bracket mold. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and melted plastic into a mold cavity under high pressure from an injection molding machine, and after cooling and solidifying, a molded product is obtained. The injection mold mainly includes a fixed mold and a movable mold. The fixed mold is installed on the fixed seat plate of the injection molding machine, and the movable mold is installed on the movable seat plate of the injection molding machine. During injection molding, the fixed and movable molds are closed, and the plastic enters the m...
