Abstract

The invention discloses an injection mold for auto parts, which includes a male mold and a female mold corresponding to the male mold; cavity connected to the first port; the upper cavity is provided with a first forming plate and a second forming plate; the lower end of the first forming plate is fixedly connected with a first connecting rod, and a push rod is arranged to move up and down in the first connecting rod; The lower end of the second forming plate is fixedly connected with a second connecting rod; it also includes a first driving device for controlling the up and down movement of the first connecting rod, a second driving device for controlling the up and down movement of the ejector rod, and a third driving device for controlling the up and down movement of the second connecting rod device. In the present invention, the demoulding is divided into two stages, which can effectively avoid the breakage of the finished product during demoulding and improve the success rate of demoulding.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to an injection mold for auto parts. Background technique [0002] When the existing injection mold is processing the plastic parts of the automobile, the melted plastic is usually cast in the mould, and the required product will be obtained after the molding is cooled and demoulded. [0003] However, when the injection mold is molding some parts with relatively deep molding positions, the parts will stick to the mold when the parts are demolded, causing the parts to break and cannot be demolded smoothly. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an injection mold for auto parts, which can successfully realize the demoulding of plastic finished auto parts. [0005] The object of the present invention is achieved through the following technical solutions: [0006] An injection mold for ...
