Embodiment
[0037] Such as figure 2 As shown, the automotive instrument panel transparent body processing device mainly includes an injection molding machine 1, a transparent body mold 2, and a hot runner connecting the injection molding machine 1 and the transparent body mold 2. Among them, the hot runner is the flow channel of the sol, and the channel can maintain the liquid state of the sol; the injection molding machine 1 is used to inject the sol into the transparent body mold 2 through the hot runner, and after the sol is cooled and formed in the transparent body mold 2, A transparent body product is obtained.
[0038] from figure 1 It can be seen that the hot runner in the prior art is a straight channel, and the glue inlet is set at a position away from the center of the transparent body mold. After the injection molding machine 1 sends the sol into the hot runner, the sol will quickly enter the transparent body along the arrangement direction of the straight channel. In the bo...

Abstract
The invention discloses a processing device for a transparent body of an automobile instrument panel, which belongs to the injection molding processing technology and mainly solves the problems of low yield rate and high production cost of the transparent body in the prior art. The device for processing the transparent body of the automobile instrument panel includes an injection molding machine, a transparent body mold, and a hot runner connecting the injection molding machine and the transparent body mold, and the hot runner is a curved hot runner. The hot runner is composed of a hot runner main body and a longitudinal runner connected to its upper end, and the hot runner main body is a "U"-shaped structure placed horizontally. At the same time, the invention also discloses the processing technology of the transparent body. Through the above-mentioned processing device and processing technology, it can effectively prevent a large amount of sol remaining on the gate at the end of injection molding from affecting the product molding of the transparent body, thereby ensuring the molding quality of the transparent body and improving the quality of the transparent body. Its yield rate is high, the sol raw material is saved, and the production cost is reduced.
Description
technical field [0001] The invention relates to an automobile dashboard, in particular to a transparent body processing device and a transparent body processing technology of the automobile dashboard. Background technique [0002] The car dashboard is an important part to ensure the safe driving of the car, and it is the centralized part of the manipulation control and display. The automobile instrument panel is mainly composed of the chassis and the cover plate installed on the chassis. The main function of the cover plate is to facilitate the driver to observe the instrument panel under the premise of ensuring the normal operation of the electronic components on the chassis. For this reason, the cover plate is Made of a transparent material, in the present invention, the cover plate is called a transparent body. [0003] In order to ensure the transparent effect of the transparent body, its production material is generally PMMA. During processing and molding, its technica...
