Forming die and forming process of automobile decoration ring

Abstract

The invention discloses a forming die and a forming process of an automobile decoration ring, and relates to the technical field of automobile decoration manufacturing equipment. According to the forming die and the forming process of the automobile decoration ring, a forming module is included, the forming module comprises a cooling plate, an annular forming groove is formed in the back face of the cooling plate, a flow guide channel connected with the forming groove is formed in the center position of the back face of the cooling plate, the flow guide channel is of a cross-shaped structure, the cross-shaped center position of the flow guide channel is connected with a feeding pipe, the feeding pipe is fixedly connected to the front face of the cooling plate and penetrates through the front face of the cooling plate to communicate with the flow guide channel. Through the arrangement of a material returning module, the forming module and a matching module are limited at the same time through limiting rods fixed to clamping plates, so that the matching mode that two parts of a traditional die are connected in an inserted mode is avoided; and in this way, the situation that in a traditional die assembly matching mode, large abrasion is generated at a hole opening of a positioning hole, and consequently die matching is not tight is avoided.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment for automobile decorations, in particular to a molding die for automobile decoration rings and a molding process thereof. Background technique [0002] The car trim is an important part of the car. What important role does it play in increasing the recognition and aesthetics of the wheel? At present, the production process of the car trim needs to go through injection molding, demoulding, cutting and other steps. The injection molding of the car trim After machine injection molding, there is generally a material head on the formed car trim. [0003] At present, there are few existing technologies for molds used for automotive trims. In the conventional injection molding process, the molds in the conventional injection molding process are positioned by using multiple positioning columns to cooperate between the molds to achieve precise positioning. The molds are repeatedly matched. ...

Problems solved by technology

[0003] At present, there are few existing technologies for molds used for automotive trims. In the conventional injection molding process, the molds in the conventional injection molding process are positioned by using multiple positioning columns to cooperate between the molds to achieve precise positioning. The molds are repeatedly matched. During the process, the positioning hole on the mold will be greatly worn out, resulting in a loose fit of the mold, and auxiliary equipment is required to complete the mold opening.
