The two fixing rods 809 are located on both sides of the special-shaped hole 805. A clamping piece 807 is embedded in the special-shaped hole 805, and the clamping piece 807 is slidably connected to the special-shaped body 804. A plurality of springs 806 are respectively fixedly connected at one end of the two clamping pieces 807 away from the special-shaped hole 805, and the other end of the spring 806 is fixedly connected to the special-shaped body 804.

[0053] Preferably, the preheating element 603 is a U-shaped silicon carbon rod or a spiral silicon carbon rod.

[0054] Among them, in a vacuum environment, the resistivity of the silicon carbon rod is significantly reduced, which means that under the same current, the silicon carbon rod will generate more heat.

[0057] The control submodule 1102 can control the up and down movement of the sliding wheel 802 . Specific embodiments

[0059] Before preheating, the vacuum submodule 1104 in the control module 11 works to realize regional vacuum. During the preheating process, the insulation board 9 is stretched to the specified position by the stretching component 7, and the clamping assembly 8 drives the mold to the preheating hole 10 to contact the preheating assembly 6. The control submodule 1102 in the control module 11 controls the preheating submodule 1103 to preheat the mold. When the temperature control submodule 1106 detects that the predetermined temperature has been reached, the preheating is stopped, and the clamping assembly 8 drives the mold to rise. During the preheating process, by heating in a vacuum environment, the heat distribution on the mold is more uniform due to the absence of air flow. At the same time, the vacuum environment can effectively reduce the loss of heat through air convection and radiation, thereby improving energy efficiency.

[0060] During the mold replacement process, the heat insulation board 9 is stretched by the stretching component 7 to fit the preheating hole 10, and is tightly closed. After the top plate 3 is opened to replace the mold, the top plate 3 is closed, and the control submodule 1102 controls the vacuum submodule 1104 on the upper partition 4 to work, so that the environment in the middle area between the upper partition 4 and the top plate 3 remains vacuum; at the same time, the gas monitoring submodule 1105 is responsible for monitoring the gas composition and concentration in the middle area between the lower partition 5 and the upper partition 4, and transmits the monitoring results to the control submodule 1102. The control submodule 1102 can adjust the vacuum or other parameters in time according to the data provided by the gas monitoring submodule 1105 to ensure that the gas environment inside the equipment meets the working requirements; after completing the above work, the replaced mold is heated. In this process, the preheating hole 10 is closed by the heat insulation board 9 to reduce heat loss and improve preheating efficiency.

[0061] The utility model adopts a detachable connection mode between most components, which has a low maintenance cost; at the same time, the control submodule 1102 is externally connected with an operation button, which is easy to operate.
