[0002] Thermoforming machine is a processing equipment used in the plastic and rubber industry. It presses materials into products of specific shapes through heat and pressure. The working principle of the thermoforming machine is to use a heating plate to heat the mold to a certain temperature, and then apply pressure to the material to form the desired shape under the heat. When producing and processing sealing rings, a thermoforming machine is needed. Thermoforming machine is also called flat plate vulcanizer, rubber vulcanizer, automatic flat plate vulcanizer, etc.

[0003] Chinese patent CN218476988U discloses a vulcanization equipment for processing rubber sealing rings, including a bottom box, columns are provided on both sides of the top surface of the bottom box, mounting grooves are provided in the columns, screws are rotatably provided in the mounting grooves, the screws are threadedly connected with a slider 1, a lifting plate is connected between the sliders 1 on both sides, a heating plate is provided on the bottom surface of the lifting plate, a mold is provided on the top surface of the bottom box, a sliding rod is provided in the bottom box, the sliding rod is slidably connected with two sliders 2, and the slider 2 passes through the top wall of the bottom box and is connected to a clamping plate arranged on one side of the mold. The utility model drives the screw to rotate by a motor 1, thereby driving the slider 1 and the lifting plate to move up and down, which is convenient for adjusting the height of the heating plate, and drives the gear to rotate by a motor 2, thereby driving the rack and the slider 2 to move left and right, thereby driving the clamping plate to move, clamping and fixing the mold to prevent it from shaking, and absorbing the waste gas generated by vulcanization through the waste gas absorption structure.
