The core pulling mechanism comprises a product, a lower die plate, a first mold core, a second mold core, a large sliding block and an air cylinder, wherein a rectangular post is arranged on the inner side wall of the product, a groove is formed in the rectangular post in the axis direction of the rectangular post,a buckle is arranged on the top of a groove, the first mold core is used for forming the upper part of the groove, the second mold core is used for forming the lower part of the groove, a bulged block which is used for forming the buckle and protrudes from the upper surface of the first mold core is arranged on the upper surface of the first mold core, a first open groove is formed in the lower die plate, the large sliding block can be matched with the interior of the first open groove in a forward and backward sliding mode, the large sliding block is driven by the air cylinder, a first sliding block is arranged on one end, which is away from the product, of the first mold core, a second sliding block is arranged on one end, which is away from the product, of the second mold core, and oneend, which is away from the product, of the second sliding block is arranged on the large sliding block. The core pulling mechanism of the automobile rear door handle has the advantages of low cost and high efficiency.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a core-pulling mechanism for an automobile rear door handle. Background technique [0002] With the development of science and technology, cars have gradually become a common means of transportation for people. The back door handle is one of the components of the car. Generally, the back door handle cover is formed by injection molding. The inner side of the back door handle cover is provided with a rectangular column. A groove is set inside the rectangular column, and an undercut is provided on the top of the groove. During injection molding, the groove and the undercut need to be core-pulled. According to the existing technology, the rear door handle cover mold needs two molds to form the groove and the underside respectively. Buckle, the groove and undercut core cannot be pulled at one time, the cost is high and the efficiency is low. Contents of the invention [0003] The te...
