Abstract
The invention discloses a joint pitched roof core pulling device reversely buckled in the narrow position of an injection mold. The device comprises a pitched roof block A (1) and a pitched roof block B (2). By the adoption of the device composed of the components, the pitched roof block A is provided with a reverse buckling profile corresponding to the reverse buckling surface of a product, the pitched roof block B is provided with an interference profile corresponding to the interference surface of the product, and the pitched roof block A and the pitched roof block B are located in a core in a spliced sliding mode. The pitched roof angle of the pitched roof block A is called the angle alpha, the pitched roof angle of the pitched roof block B is called as the angle beta, and the angle beta is larger than the angle alpha; in the working process, an ejector plate pushes the pitched roof block A and the pitched roof board B to simultaneously conduct pitched roof mold release, due to the fact that the angle beta is larger than the angle alpha, a gap is vacated for pulling the pitched roof block A from the reverse buckling surface of the product while the pitched roof block B is pulled out of the interference surface of the product, the pitched roof block A avoids the interference surface and can be smoothly pulled out of the reverse buckling surface, by the adoption of the joint pitched roof core pulling scheme, interference is avoided in the core pulling process through the reverse buckling structure of the narrow position of the injection mold product, and the purpose that mold release is easily conducted through pitched roof core pulling is achieved.
