Problems solved by technology
[0004] The technical problem to be solved by the present invention is: in order to solve the traditional penetrating taillight cover in the prior art due to its two-color covering form, the transparent sheet needs a hot runner to point the gate directly on the surface of the plastic product, which will form residual traces of the gate on the transparent sheet , the technical problem that affects the appearance of the transparent sheet, the present invention provides a through-type tail light cover flip mold mechanism, through the improved design of the mold, the transparent sheet can be injected first, and then the lower mold can be rotated horizontally by 180° to make the black sheet Injection molding, the first injection cavity of the injection molded black sheet covers a part of the transparent sheet to dilute or cover up the residual traces on the transparent sheet, so as to improve the aesthetics of the transparent sheet and beautify the shape of the lampshade

Abstract
The invention relates to the technical field of lampshade injection molds, in particular to a through type tail lampshade inverted mold mechanism which comprises an upper mold and a lower mold, and a first injection cavity is formed in the upper mold; the lower mold is covered with the upper mold, a second injection molding cavity is formed in the lower mold, when the upper mold is covered with the lower mold, the first injection molding cavity and the second injection molding cavity are staggered in position, and after the lower mold horizontally rotates by 180 degrees along the midline point of the lower mold in the horizontal plane, the second injection molding cavity corresponds to the first injection molding cavity in position; an injection molding opening is formed in the upper mold, the area where the trace of the injection molding opening left on the product formed in the second injection molding cavity is located is an area B, and after the lower mold rotates by 180 degrees, the first injection molding cavity completely covers the area B. According to the invention, through the improved design of the mold, the injection molding of the transparent sheet can be completed firstly, then the injection molding of the black sheet can be completed after the lower mold is horizontally rotated by 180 degrees, and the black sheet can cover the residual trace on the transparent sheet after injection molding, so that the aesthetic property of the transparent sheet is improved.
Description
technical field [0001] The invention relates to the technical field of automotive lamp molds, in particular to a through-type tail lamp cover flip-chip mold mechanism and a lamp cover injection molding process. Background technique [0002] At present, with the continuous improvement of public aesthetics and the diversification of automobile appearance, the requirements of the automotive lamp industry are also constantly improving. Whether it is the internal optical requirements, or the external modeling and structural requirements are getting higher and higher. In order to achieve a breakthrough in the shape and function of the lamp, it is often necessary to carry out a greater degree of bold innovation in the mold. On the basis of ensuring the stability and uniformity of the mold, it is necessary to do everything possible to meet the appearance and structural requirements of the lamps. [0003] In the process of lampshade, it is often necessary to carry out two-color inj...
