Description

An ejection mechanism of a forming mold for an automobile lamp mask

technical field

The utility model belongs to the technical field of moulds, and relates to a mold for forming an automobile lamp mask, in particular to an ejection mechanism of the mold for forming an automobile lamp mask.

Background technique

In the automotive industry, various molds such as stamping molds, injection molds, forging molds, casting wax patterns, glass molds, etc. are widely used in the production of automotive interiors and panels. Among them, the headlight cover is manufactured by injection molding process, using an injection molding mold.

Injection molding molds usually consist of two parts: a moving mold and a fixed mold. The moving 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 mold through the ejector mechanism.

For example, Chinese patent [application number 201020260816.5; authorized announcement number CN201755900U] discloses a secondary ejection mechanism for automobile lampshade molds, including an upper template and a lower template. The thimble plate and the thimble double plate, the thimble plate and the thimble double plate are connected with the thimble, the movable template is installed on the mold foot, the corner insert is installed in the movable template, and the mold cavity is formed between the corner insert, the movable template and the fixed template. There is a molded automobile cover, the thimble passes through the movable template and the corner insert to contact the automobile cover, the ejector plate and the ejector doubler are arranged in the mold foot, the ejector plate and the ejector doubler are connected to the ejector, and the ejector Connect the knuckle inserts through the ejector plate, the ejector doubler plate and the movable formwork, and install limit screws between the ejector pin plate and the ejector pin doubler plate and the ejector pin plate and the ejector pin doubler plate.

The above-mentioned secondary ejection mechanism of the automobile lampshade mold first pushes the corner insert and the automobile lampshade out of the template by the ejector pin, and then the automobile lampshade is forced to be ejected from the corner insert by the thimble. The problems of such ejection mechanism are: 1. The force of the ejector pin on the automobile lampshade is concentrated at one point, which may easily cause damage to the surface of the automobile lampshade and affect the quality of the automobile lampshade; 2. The ejector pin will force the automobile lampshade to be ejected from the corner insert. The acceptance of the corners is relatively large, which may easily cause the car lampshade to break at the corners, resulting in scrapped products.
