An adhesive is required, and the process and cost are increased. 3. When in bonding, a certain probability exists that the decorative cloth is mounted and not adhered, so that the whole product is scrapped.
Disclosure of Invention
The utility model aims to solve the technical problem of providing an injection mold for an automobile B-pillar trim panel, which is characterized in that decorative cloth is placed in an inner cavity of the mold before injection molding, so that a molded part and the decorative cloth are directly and fixedly connected into a whole after injection molding.
The technical scheme of the utility model is that the injection mold of the automobile B column interior trim panel with the following structure comprises a movable mold and a fixed mold; the inner surface of the movable die is provided with two protruding forming ends, the inner surface of the fixed die is provided with a sliding block and an oil cylinder for driving the sliding block, the surface of the sliding block is provided with two parallel concave cavities, and each forming end and a corresponding concave cavity form a cavity for forming the B-pillar inner decorative plate; the method is characterized in that: the edge of each concave cavity is provided with a positioning structure, and decorative cloth is placed before molding and positioned by the positioning structure; and after injection molding, fixedly connecting the B-pillar inner decorative plate in the cavity with the decorative cloth into a whole.
In the first step of molding, the movable mold and the fixed mold are opened, and the oil cylinder pushes the sliding block to extend out of the fixed mold.
And a second molding step: and placing the decorative cloth into the concave cavity of the extending sliding block, and positioning the decorative cloth through a positioning structure.
And thirdly, the oil cylinder pulls the sliding block to shrink into the fixed die, and the movable die and the fixed die are clamped and molded to fix the molded B-pillar inner decoration plate and the decoration cloth.
The positioning structure comprises a plurality of positioning pins, the positioning pins are arranged outside the edge of the concave cavity, the appearance of the decorative cloth is larger than the surface of the concave cavity, and the edge of the decorative cloth is inserted into all the positioning pins.
After adopting the structure, the utility model has the following advantages: the decorative cloth is placed in the inner cavity of the die before injection molding, so that the molded part and the decorative cloth are directly and fixedly connected into a whole after injection molding, and the three advantages are achieved: 1. the subsequent bonding process is reduced, the process is saved, and the processing efficiency is improved. 2. And an adhesive is not needed, so that the working procedures and the cost are reduced. 3. The molded part and the decorative cloth can be well attached by using the pressure of the mold, so that the existence of non-attaching is eliminated, and the qualification rate is increased.
