Automatic trimming device for gate in injection molding process of automobile lamp

Abstract

The invention relates to an automatic dressing device for a sprue formed during the injection molding process of a car lamp. The automatic dressing device comprises a worktable, telescopic driving parts, following mechanisms and grinding head adjusting mechanisms. One end of each telescopic driving part is hinged to the worktable, and the other ends of the telescopic driving parts are hinged to follower plates of the following mechanisms. Guiding grooves of which the contour shapes are the same as that of a dressed sprue are formed in following guide rail plates of the following mechanisms. Two longitudinal guide rails are arranged on two sides of each following guide rail plate. Two transverse guide rails are arranged at the upper part of each guide rail mounting base. Two longitudinal sliding blocks at the lower part of each guide rail mounting base are matched with the corresponding longitudinal guide rails and can move. Windows are arranged on the guide rail mounting bases. Camshafts arranged on the follower plates penetrate through the windows on the guide rail mounting bases and are arranged in the guiding grooves in the following guide rail plates. Two transverse sliding blocks at the lower part of each follower plate are matched with the corresponding transverse guide rails and can move. The grinding head adjusting mechanisms are mounted on the follower plates. The automatic dressing device is simple in structure, wide in application range, low in manufacturing cost, and high in operation stability, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to an automatic trimming device for a gate in the injection molding process of a car lamp, which belongs to the technical field of car lamp manufacturing. Background technique [0002] Today, the automobile industry is booming and thriving. However, in the injection molding process of car lights, due to the complex shape of car lights and high appearance requirements, the development cost of injection molds is getting higher and higher. At present, in the injection molding process of car lights, there is a problem that the gate is left on the product after injection molding. If the gate is trimmed manually, the quality of the finished product will be different, and the quality and instability will be different. The existence of will seriously affect the comprehensive quality of finished product loading; if the gate is simply solved from the injection mold, a lot of cost will be invested. Since the shape of the lamp is mostly a c...

At present, in the injection molding process of car lights, there is a problem that the gate is left on the product after injection molding. If the gate is trimmed manually, the quality of the finished product will be different, and the quality and instability will be different. The existence of will seriously affect the comprehensive quality of finished product loading; if the gate is simply solved from the injection mold, a lot of cost will be invested

Since the shape of the lamp is mostly a curved surface structure, two grinding heads are required to trim the gate at the same position during conventional grinding, resulting in a complex mold structure
