[0035] According to the above scheme: the supporting device 5 includes a connecting lower template 51, a water tank 52, a mold pressing groove 54, positioning rods 53, and a cooling assembly 55. First, the rubber raw material is placed in the mold pressing groove 54 in the middle of the upper end of the connecting lower template 51. The connecting lower template 51 is fixed to the middle of the upper end of the base 1, serving as the basic supporting platform for rubber molding. The shape of the mold pressing groove 54 determines the shape of the rubber after molding. The positioning rods 53 around the upper end of the connecting lower template 51 have their other ends fixed to the lower end of the horizontal plate 3, and their positions and dimensions are consistent with... The positioning hole 410 at the lower end of the upper mold plate 42 is adapted to the positioning hole.

The circulating water carries away heat, thus cooling the mold and rubber. The water tank 52 has a long rectangular structure and is located outside the mold pressing groove 54, which facilitates the arrangement of the condenser pipe 552 and the circulation of water. The design of the mold pressing groove 54 allows the rubber raw material to be formed in a specific shaped space, ensuring the shape accuracy and consistency of the product. The precise design of the positioning rod 53 ensures the accuracy of the upper and lower mold closing, avoiding poor molding caused by positional deviation and improving product quality. The water box 551 and the condenser pipe 552 in the cooling assembly 55 work together to effectively cool the mold and rubber by utilizing the heat exchange characteristics of water, improving cooling efficiency. The cooling process can be controlled by a switch valve, making operation convenient and flexible. The water tank 52 provides suitable space for the condenser pipe 552, improving the uniformity and stability of cooling and helping to produce high-quality rubber products.
[0036] It should be noted that this utility model is a precision rubber production mold. When this precision rubber production mold is in operation, the rubber raw material is first placed in the mold pressing groove 54 at the middle of the upper end of the connecting lower template 51 of the bearing device 5. Then, the hydraulic cylinder 41 in the lifting device 4 is activated. The output end of the hydraulic cylinder 41 pushes the upper mold plate 42 downwards. The cylindrical rubber mold body 47 at the middle of the lower end of the upper mold plate 42 then moves closer to the mold pressing groove 54 and extrudes the rubber raw material. During this process, the other ends of the four positioning rods 53 are fixed to the lower end of the horizontal plate 3, and their position and dimensions are matched one-to-one with the four positioning holes 410 at the lower end of the upper mold plate 42, playing a precise positioning role and ensuring the accuracy of the upper and lower mold closing. Simultaneously, the two side plates 44 on the left and the two side plates 44 on the right... The short screw 46 is connected to the upper mold plate 42 and movably connected to the outer surface of the corresponding support rod 2, which plays an auxiliary guiding and stabilizing role in the movement of the mold. After the rubber is molded, the cooling fan device 49 in the mounting box 48 can be turned on to dissipate heat and cool the upper mold plate 42 and the cylindrical rubber mold body 47, accelerating the curing and shaping of the rubber. In addition, the cooling component 55 in the bearing device 5 can also cool the mold and the rubber. The water in the water box 551 can be controlled to enter and exit through the first connecting pipe 555 and the second connecting pipe 556 respectively. The condenser pipe 552 connected to the second connecting pipe 556 is located in the water tank 52, and the water tank 52 has a long rectangular structure located outside the mold pressing groove 54. The heat is carried away by the circulation of water, which further improves the cooling effect, thereby efficiently completing the rubber production process.
