Problems solved by technology

[0005] The problem with the above-mentioned automotive lampshade injection mold is that, by arranging multiple sliders for molding and ejecting the lampshade, 1. During the molding process, gaps are easily formed between the sliders and between the sliders and other parts , during the molding process, the material enters the gap, which makes the inner surface of the molded lamp cover form strip-like protrusions, which affects the quality of the inner surface of the lamp cover; 2. During the ejection process, it is difficult to ensure that the lamp cover is separated from the mold

Embodiment 1

[0036] The automobile lamp mask forming mold includes a movable mold 1 and a fixed mold 2. The movable mold 1 includes a bottom plate 1a, a movable mold plate 1b, a large inclined roof 1c and an ejection mechanism, and the fixed mold 2 includes a fixed mold plate 2a and a concave mold 2b. The movable mold 1 and the fixed mold 2 are installed on an injection molding machine. When the movable mold 1 and the fixed mold 2 are closed, the large inclined top 1c, the internal sliding block 1d and the concave mold 2b form a cavity for molding the vehicle light mask 12. The movable mold 1 and the fixed mold 2 complete the molding of the vehicle lamp mask 12 in the closed state, and the movable mold 1 and the fixed mold 2 are opened to take out the molded vehicle lamp mask 12.

[0037] Specifically, such as figure 1 As shown, the upper surface of the fixed mold plate 2a is fixed with a hot runner frame plate 2d, and a heat shield plate 2e is also provided between the hot runner frame plate ...

Embodiment 2

[0049] The technical solution in this embodiment is basically the same as that in the first embodiment. The difference is that in this embodiment, the ejector mechanism includes an ejector plate 9 horizontally arranged on the movable template 1b and fixed on the movable template 1b. On the cylinder, the large inclined top 1c is obliquely arranged on the ejector plate 9. The ejector plate 9 is also vertically provided with an ejector rod 10, the end of the ejector rod 10 is fixed with a demolding slider 11, and the piston rod of the cylinder is fixed on The ejector plate 9 is at the bottom, and when the ejector plate 9 slides toward the movable template 1b, the large inclined roof 1c moves horizontally relative to the ejector plate 9 and the distance between the large inclined roof 1c and the demolding slider 11 increases.

Abstract

The invention provides an automobile lamp housing forming mold which belongs to the technical field of molds, and solves the problem of low forming quality of an existing automobile lamp housing forming mold. The automobile lamp housing forming mold comprises a moving mold and a fixed mold, wherein the fixed mold comprises a fixed mold plate, and a concave mold is arranged on the inner side of the fixed mold plate; the moving mold comprises a bottom plate, a moving mold plate and a big strip-shaped pitched roof; the bottom plate and the moving mold plate are arranged along the horizontal direction; a guiding inclined hole is obliquely formed in the moving mold plate; the big pitched roof runs through the guiding inclined hole along the inclined direction; the moving mold plate extends from the two ends of the big pitched roof respectively, an inner drawing slide block is fixed on the bottom plate along the direction vertical to the bottom plate; when the moving mold and the fixed mold are assembled, the big pitched roof, the inner drawing slide block and the concave mold form a cavity used for forming a lamp housing; and an ejector mechanism is arranged on the moving mold plate, and is used for driving the big pitched roof to slide relatively to the moving mold plate along the inclined direction to eject out the formed lamp housing. The automobile lamp housing forming mold is capable of improving the forming quality of the inner surface of the lamp housing.

Description

Technical field [0001] The invention belongs to the technical field of molds, and relates to a molding mold for automobile lamp masks. Background technique [0002] In the automotive industry, a large number of molds are used in the production of automotive interiors and automotive panels, such as stamping molds, injection molds, forging molds, casting wax molds, and glass molds. Among them, the car lamp mask is manufactured through an injection molding process, using an injection molding mold. [0003] The injection molding mold is usually composed of a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are combined to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated, and the product is separated from the...
