Background

The prior art is a product, which is a sealing element used for automotive interiors, the prior art is a mold for producing the shape of the sealing element, the prior art structure is formed by sequentially combining an upper mold, a panel and a middle plate from top to bottom, a plurality of panels are arranged on the panel and are mutually attached side by side, a through hole is formed after the adjacent two panels are spliced by a notch structure on the side surface of the panel, after the mold is closed, the upper cavity and the through hole on the bottom surface of the upper mold are filled with raw materials after the raw materials are thermally fused, and a lower cavity formed on the surface of the middle plate is formed, and after the mold is cooled, the product is formed.

However, in the conventional structure, when demoulding, a product is blown out from the panel by means of a wind gun in a high-pressure mode;

the problems associated with this conventional structure are mainly manifested in the following points:

1. the single inlaid strip can not be removed at one time, the heated inlaid strip is removed while being heated, the thickness of the inlaid strip is smaller and is within +/-2 mm, so that the inlaid strip is easy to bend and deform during removal, an arched state is formed, and a produced product is failed;

2. in addition, due to the lack of a structure for protecting the side surface, in workshops storing a large amount of materials, tools, equipment and the like, the side surfaces of the panel are easy to collide after being disassembled, so that various curled edges and the like can occur, and in the product generated under the circumstance, burrs can occur on the surface of the product due to the fact that the fit between the panels is not corresponding.

3. The product after molding is uncontrollable in the upper cavity and the lower cavity, the product with strong viscosity with the lower cavity is remained in the lower cavity in the film forming process, the product with weak viscosity with the lower cavity is taken away along with the upper die plate, the strip participating in die casting molding is taken away, and the situation that the viscosity is uncontrollable can lead to inconsistent positions of the strip before and after film forming, so that the strip can deform.
