Problems solved by technology

[0002] With the development of science and technology, cars have gradually become a common means of transportation for people. The back door of a car is one of the components of a car. Generally, the back door of a car is formed by injection molding with an injection mold. According to the existing technology, during injection molding, since the undercut and cross ribs are respectively located in the two side walls, it is easy to strain the product when the core is pulled, and the reliability is poor.

Abstract

The invention discloses an automobile rear door mold, which comprises a product, a thimble plate, a ejector rod and an inclined guide rod. The lower surface of the product is provided with an opening groove, the front inner wall of the opening groove is provided with an undercut, and the opening The top of the groove is provided with a cross rib, and the ejector plate is located below the product. It also includes the first mold core for forming the front inner wall of the open groove and the undercut, and the mold core for forming the rear inner wall of the open groove and the cross rib. The second mold core and the ejector rod, the upper end of the inclined guide rod is pressed against the lower surface of the first mold core, the lower end of the inclined guide rod is arranged on the ejector plate, and the described inclined guide rod can drive the first die The core is separated from the undercut, the upper end of the ejector rod is pressed against the lower surface of the second mold core, the lower end of the ejector rod is set on the ejector plate, and the upper end of the ejector rod penetrates through the second mold core and is pushed against the product. The lower end of the above-mentioned ejector rod is arranged on the ejector plate, and the invention provides an automobile rear door mold which is not easy to damage the product and has high reliability.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an automobile rear door mold. Background technique [0002] With the development of science and technology, cars have gradually become a common means of transportation for people. The back door of a car is one of the components of a car. Generally, the back door of a car is formed by injection molding with an injection mold. According to the prior art, during injection molding, since the undercut and the cross ribs are respectively located in the two side walls, it is easy to strain the product when the core is pulled, and the reliability is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art and provide an automobile rear door mold which is not easy to damage the product and has high reliability. [0004] The technical solution adopted by the present invention is: a mold for the r...
