[0002] With the development of automobile industry and economic level, cars have entered ordinary families. Automobile guard plates are important protective, decorative and functional parts of automobile exterior systems. They can resist the stones brought up during driving and hit the car body, play a role in protecting sheet metal parts and extending their service life. Automobile guard plates mostly include bottom guard plates, side bottom guard plates, front guard plates, rear guard plates and wheel cover guard plates, etc. Among them, the side bottom guard plates are installed between the car door and the bottom guard plate to prevent mud, water, sand and the like from entering. Since the structure of the automobile side bottom guard plate is relatively complex and has many uneven structures, die casting is often used in the molding process. The die-casting mold for automobile side bottom guard plates currently used has a complex structure, is not convenient for processing and assembly, and is difficult to maintain in the later stage. Therefore, a molding mold for automobile side bottom guard plates with a relatively simple structure is needed.

[0003] After searching, the patent application number is (202023155905.6), which discloses "a kind of automobile underbody guard plate forming mold", which solves the problem that the cooling water circuit of the forming mold body is generally single-circuit or double-circuit. During the production process, the water temperature of the low-temperature inlet water gradually increases when it flows to the outlet position, which causes the mold surface temperature at the water inlet position to be low, the mold surface temperature at the water outlet position to be high, and the mold has a step temperature difference along the water flow direction;

[0004] However, the above device has the following problems: since the mold is generally heavy as a whole, the existing device lacks a buffer mechanism when the mold is closed, which leads to collisions and damage to the mold during mold closing. In addition, during production, the product needs to be guided, and the existing mold guidance is poor and difficult to align, which leads to displacement and deformation of the bracket, resulting in a high product scrap rate. For this reason, we propose an anti-deformation automobile underbody guard molding mold to solve the above problems. Utility Model Content
