Cooling tray groove 62. Cooling fan 63. Semiconductor cooling chip assembly board 64. And conversion power supply 65. The front end face of the hot press base 1 is provided with a finished product cooling chamber 61. The left and right end faces of the finished product cooling chamber 61 are respectively equipped with cooling tray grooves 62. The left and right end faces of the hot press base 1 are respectively equipped with cooling fans 63. The lower surface of the lower mold plate 4 is equipped with a semiconductor cooling chip assembly board 64. This design solves the problem that the temperature of the lower mold plate is high after the original device completes hot pressing and molding, and the heat of the mold plate can only be dissipated into the air, resulting in heat loss and indirectly wasting a lot of electrical energy.

[0019] As the first embodiment of this utility model: Four cylinder adjusting screws 31 are installed on the upper surface of the hot press base 1. The four cylinder adjusting screws 31 penetrate the upper and lower surfaces of the top cylinder support 3. Two support fixing nuts 32 are installed on the circumferential surface of each cylinder adjusting screw 31. Each set of two support fixing nuts 32 is located on the upper and lower surfaces of the top cylinder support 3. The cylinder adjusting screws 31 are threadedly connected to the top cylinder support 3 and the support fixing nuts 32. An electric heating plate 21 is installed on the lower surface of the top hot press cylinder 2. By adding support fixing nuts 32, the height of the electric heating plate 21 can be freely adjusted, improving the applicability of the hot press forming machine. Two... A translation drive motor 42 is provided, and a mold translation screw 41 is installed on the front end face of each translation drive motor 42. Each mold translation screw 41 passes through both ends of the lower mold plate 4 and is connected to the lower mold plate 4 by threads. Mold supports 51 are installed at both ends of the upper surface of the lower mold plate 4. A lifting drive motor 52 is installed on the rear end face of the top of each mold support 51. A mold lifting screw 54 is installed on the lower surface of each lifting drive motor 52. Mold lifting blocks 57 are installed on the left and right end faces of the upper mold plate 5. Mold rotation shafts 56 are installed on the inner surfaces of the two mold lifting blocks 57 and pass through the left and right surfaces of the upper mold plate 5. A cylinder lifting groove 58 is provided at the upper end of the upper mold plate 5. The cylinder lifting groove 58 is connected to the mold support 51. A rotary drive cylinder 53 is installed inside the cylinder lifting groove 58. The lower surface of the rotary drive cylinder 53 is connected to the upper mold plate 5 by a rotary connection hinge 55.

[0020] As a second embodiment of this utility model: When adding rubber raw materials, firstly, the lifting drive motor 52 is started. The lifting drive motor 52 drives the mold lifting screw 54 to rotate. Since the mold lifting screw 54 and the mold lifting block 57 are connected by threads, and the upper mold plate 5 cannot rotate, the mold lifting screw 54 will drive the upper mold plate 5 to rise. The upper mold plate 5 will drive the rotary drive cylinder 53 to rise in the cylinder lifting groove 58. At this time, the rotary drive cylinder 53 is shortened, and the upper mold plate 5 will rotate around the mold rotation shaft 56. Then, raw materials are added to the lower mold plate 4. Then, the upper mold plate 5 and the lower mold plate 4 are re-attached together. The translation drive motor 42 is turned on, which drives the mold translation screw 41 to rotate. The mold translation screw 41 will drive the lower mold plate 4 and the upper mold plate 5 to move downwards under the electric heating plate 21. After the translation is completed, the top hot pressing cylinder 2 is extended. The extended top hot pressing cylinder 2 presses the electric heating plate 21 onto the upper mold plate 5 to melt and shape the rubber. After shaping, the lower mold plate 4 will return to its original position. At this time, the cooling fan 63 is turned on. At the same time, the temperature of the lower mold plate 4 will be conducted to the semiconductor cooling chip assembly plate 64. The temperature difference between the upper surface and the lower surface of the semiconductor cooling chip assembly plate 64 will form a large temperature difference, thereby enabling the semiconductor cooling chip assembly plate 64 to generate electricity. The electrical energy generated by the semiconductor cooling chip assembly plate 64 will be supplied to the cooling fan 63 through the power conversion power supply 65. The continuous rotation of the cooling fan 63 can ensure that the temperature of the finished product cooling chamber 61 is low. Then, the finished product and finished product tray are placed in the cooling tray slide 62 for cooling.
