AI Technical Summary
Technical Problem
In the existing technology, the internal parting demolding structure of the textured car bumper is difficult to demold smoothly under the condition of high deformation resistance, and it is easy to tear the surface texture, which affects the product quality.
Method used
An external deformation method is adopted, in which the end of the bumper is deformed by pushing the external block, combined with an anti-deformation mechanism to prevent excessive deformation and ensure smooth demolding.
Benefits of technology
This method enables stable demolding of textured car bumpers, preventing the inner extraction mechanism from falling off and the texture from being damaged, thus ensuring product quality.

Abstract
The present application belongs to the field of injection mold, and particularly relates to a demolding method of a skin pattern automobile bumper mold, the mold comprises a cavity part and a core part, and the cavity part and the core part are connected by an injection molded skin pattern automobile bumper, the core part comprises a core plate, a large top block is arranged on the core plate, the cavity part comprises a cavity frame, the end of the skin pattern automobile bumper is embedded in the cavity frame, the end of the skin pattern automobile bumper is provided with a side edge, an inclined top block is arranged in the core plate, the inclined top block is matched with the inner wall of the end of the skin pattern automobile bumper and the inner wall of the side edge, an outer push block is slidably arranged on the core plate, the outer push block is matched with the bottom surface of the end of the skin pattern automobile bumper and the outer wall of the side edge, when demolding, the inclined top block first leaves a deformation space, then the outer push block pushes the end of the skin pattern automobile bumper and the side edge to deform inwardly, so that the end of the skin pattern automobile bumper is demolded from the cavity frame.
