Technical Field

[0001] The utility model relates to the technical field of rubber molds, in particular to a high-efficiency and energy-saving rubber mold heating device. Background Art

[0002] In the production of rubber products, some process steps do require mold heating. For example, during the vulcanization process, many rubber materials must reach a certain temperature to undergo a cross-linking reaction, thereby solidifying into the desired shape and properties. Here, the mold acts as a heat transfer medium, and controlling its temperature is crucial to the quality of the rubber product. Proper heating ensures that the rubber material reaches the vulcanization temperature evenly and quickly, resulting in the desired product.

[0003] However, the current heating device has a simple structure and lacks protection against heat loss, causing heat to continue to diffuse to the outside, resulting in a significant increase in heating power consumption. In addition, after the upper and lower molds are opened, a large amount of unpleasant gas generated by heating the rubber mold is easily emitted into the air, polluting the working environment.

[0023] In this embodiment, a base 8 is installed on the bottom surface of the lower mold 13, and both sides of the base 8 protrude to form a fixed plate 7, on which a cylinder 6 is installed. A top plate 5 is installed on the outer ring surface of the sealing shell 1 facing the cylinder 6, and the piston rod of the cylinder 6 is installed on the top plate 5.

[0024] In this embodiment, an air outlet pipe 3 communicating with the sealed cavity is installed on the outer ring surface of the sealed shell 1, and multiple air inlet pipes 4 are installed on the top surface of the sealed shell 1. The interiors of the air inlet pipes 4 form air inlet holes communicating with the sealed cavity.

[0025] In this embodiment, multiple grooves 10 are provided on both sides of the base 8, and fixing holes 9 are provided on the bottom surfaces of the grooves 10 and pass through the base 8. Bolts can pass through the fixing holes to fix the base on the platform to ensure the installation stability of the lower mold.
