[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, a mold for producing an automotive shield includes a bottom mold 1, a top mold 2, an air jet structure, an air supply structure, and a cooling structure. The bottom mold 1 and the top mold 2 are arranged vertically opposite each other.

[0025] The jetting structure is arranged on the bottom mold 1 and is used to spray gas into the bottom mold 1 and the top mold 2. The jetting structure includes two jetting pipes 32 and a connecting pipe 34. The two jetting pipes 32 are located on both sides of the bottom mold 1. Each jetting pipe 32 is connected by two connecting rods 31. The two jetting pipes 32 are connected by the connecting pipe 34. Each jetting pipe 32 has several jetting holes 33. The several jetting holes 33 on one jetting pipe 32 are all facing the top surface of the bottom mold 1, and the several jetting holes 33 on the other jetting pipe 32 are all facing the bottom surface of the top mold 2. The several jetting holes 33 on the same jetting pipe 32 are evenly distributed.

[0026] The main structure of the automotive shield production mold consists of a bottom mold 1 and a top mold 2, which are arranged vertically opposite each other to form the shape of the automotive shield during the stamping process. The air jet structure is arranged on the bottom mold 1 and consists of two air jet pipes 32 and a connecting pipe 34. The two air jet pipes 32 are located on both sides of the bottom mold 1 and are firmly connected together by a connecting rod 31. The two air jet pipes 32 are interconnected by the connecting pipe 34. Each air jet pipe 32 has several air jet holes 33 evenly opened. This design can ensure that the gas can be evenly and comprehensively sprayed between the bottom mold 1 and the top mold 2, thereby providing the necessary gas pressure during the stamping process to help form the shape of the automotive shield. Among them, the air jet holes 33 on one air jet pipe 32 face the top surface of the bottom mold 1, and the air jet holes 33 on the other air jet pipe 32 face the bottom surface of the top mold 2. This layout further enhances the gas jetting effect.

[0027] An air supply structure is arranged between the bottom mold 1 and the top mold 2 to supply air to the air jet structure. The air supply structure includes a sealing cylinder 41, a sliding plug 42, a push rod 43, and a fixing plate 44. The sealing cylinder 41 is fixed to the side of the bottom mold 1 by a bracket. The sliding plug 42 is slidably connected to the inner surface of the sealing cylinder 41. The sliding plug 42 and the inner bottom surface of the sealing cylinder 41 are connected by a spring 45. One end of the push rod 43 is fixedly connected to the sliding plug 42, and the other end extends to the outside of the sealing cylinder 41. The fixing plate 44 is fixed to the side of the top mold 2. The end of the push rod 43 located outside the sealing cylinder 41 is fixedly connected to the fixing plate 44. An air supply pipe 46 is connected to the sealing cylinder 41.

[0028] The gas supply structure is responsible for supplying the required gas to the jet structure. It is arranged between the bottom mold 1 and the top mold 2 and consists of components such as a sealing cylinder 41, a sliding plug 42, a push rod 43, a fixing plate 44, and a spring 45. The sealing cylinder 41 is fixed to the side of the bottom mold 1. The sliding plug 42 slides and seals inside the sealing cylinder 41 and is connected to the spring 45. One end of the push rod 43 is fixedly connected to the sliding plug 42, and the other end is connected to the top mold 2 through the fixing plate 44. When the top mold 2 moves up and down during the stamping process, it will drive the push rod 43 and the sliding plug 42 to slide inside the sealing cylinder 41, thereby changing the gas pressure inside the sealing cylinder 41. When the top mold 2 moves down, the sliding plug 42 is pushed by the compression spring 45, the gas pressure inside the sealing cylinder 41 increases, and then gas is supplied to the jet structure through the gas supply pipe 46.

[0029] The cooling structure is arranged on the top mold 2 and is used to cool the gas. The cooling structure includes a cooling seat 51, a semiconductor refrigeration chip 52 and a cooling pipe 53. The cooling seat 51 contains a cooling box. The side of the cooling seat 51 has an installation port. The semiconductor refrigeration chip 52 is installed in the installation port. The cooling surface of the semiconductor refrigeration chip 52 faces the inside of the cooling seat 51 and the heat-conducting surface of the semiconductor refrigeration chip 52 faces the outside of the cooling seat 51. The cooling pipe 53 is fixed inside the cooling seat 51 and is immersed in the coolant. The cooling pipe 53 has a serpentine tube structure and is made of pure copper. One end of the cooling pipe 53 is connected to the end of the gas supply pipe 46 away from the sealing cylinder 41. The other end of the cooling pipe 53 is connected to a connecting pipe. The end of the connecting pipe away from the cooling pipe 53 is connected to the middle of the connecting pipe 34.

[0030] The cooling structure is arranged on the top mold 2 to cool the injected gas. The cooling structure consists of a cooling seat 51, a semiconductor refrigeration chip 52, and a cooling pipe 53. The cooling seat 51 is filled with coolant. The semiconductor refrigeration chip 52 is installed on the side of the cooling seat 51 with its cooling surface facing the coolant and its heat-conducting surface facing outward to dissipate heat. The cooling pipe 53 has a serpentine tube structure and is immersed in the coolant. One end is connected to the gas supply pipe 46, and the other end is connected to the middle of the connecting pipe 34 through a connecting pipe. When the gas enters the cooling pipe 53 from the gas supply pipe 46, it is cooled by the coolant and the semiconductor refrigeration chip 52 together, and then sprayed between the bottom mold 1 and the top mold 2 through the connecting pipe 34.

[0031] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
