The plastic mold is characterized in that the rear mold body is internally provided with an inclined jacking mechanism, the inclined jacking mechanism comprises a supporting plate arranged in the rear mold body, the supporting plate is provided with an ejector panel, the ejector panel is provided with a pitched roof, a product inverted buckle is arranged at the upper end of the pitched roof, the supporting plate is provided with a pitched roof guide jacking block, the ejector panel is arranged on the pitched roof guide jacking block, and a mold locking assembly for delaying releasing of the inverted buckle is arranged between the ejector panel and a rear mold base plate of the rear mold. The plastic mold aims to overcome defects in the prior art and is simple in structure and provided with the inverted buckle anti-breakage device.
Description
technical field [0001] The invention relates to a plastic mold with an undercut anti-breaking device. Background technique [0002] In the process of mold production, sometimes the undercut of the product is too long, and the product requires a small undercut deformation. Due to design defects, the traditional inclined roof structure does not meet the requirements, and the undercut is likely to be broken, or The deformation is too large to meet the product requirements. [0003] Therefore, the existing undercut device needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a plastic mold with a simple structure and an undercut anti-breaking device. [0005] In order to achieve the above object, the present invention adopts the following scheme: [0006] A plastic mold with an undercut anti-breaking device, comprising a front mold and a rear mold, characterized in ...
