Description

Technical Field

[0001] The utility model relates to the technical field of forming concave die equipment, in particular to a forming concave die for a decorative cover of an automobile nut. Background Art

[0002] There are many different rim styles on the market, which have greatly improved the appearance of the vehicle. However, most car tires are fixed to the car drive shaft by bolts and nuts, and these nuts are usually exposed outside the car wheel hub and are in direct contact with the outside air, which not only greatly reduces the overall aesthetics of the car model, but also causes rust under the erosion of the natural environment, reducing the strength of the nut and bolt when they are matched. Aiming at the production and processing of existing automobile nut decorative covers, an injection molding mold for automobile nut decorative covers is designed, which greatly improves the efficiency of conventional molding processing.

[0003] The application number is CN202120881790.4, which discloses a molding die for automobile nut decorative covers, which relates to the field of automobile nut decorative cover processing and molding, and aims to solve the problem that the molding module in the existing automobile nut decorative cover molding die is set as an integral whole, which causes the nut decorative cover to adhere to the molding die after molding, making it difficult to unload, and reducing the efficiency of the nut decorative cover molding. It includes a molding die, a die guide plate, a die guide plate fixing plate, and a guide column. The die guide plate is fixedly connected to the bottom of the molding die by fasteners. The molding die has a simple overall structure and a compact design, which is convenient for the staff to install and process. The molding die completes the injection molding of the nut decorative cover with the cooperation of the bottom die guide plate and the die guide plate fixing plate. Compared with the conventional processing method, the processing cycle is greatly shortened and the processing efficiency is greatly improved.

[0004] The above document discloses a concave die for forming a decorative cover for an automobile nut, which has the following defects: since nuts of different sizes require different decorative covers, when the size of the injection molding mold needs to be changed, the concave die is a fixed structure and cannot be disassembled, which reduces the practicality of the mold.

[0005] It can be seen from this that the existing automotive nut decorative cover forming concave die does not have the function of replacing molds of different sizes, and it is necessary to improve the existing deficiencies and provide a function of replacing molds of different sizes.
