[0021] The mold base 1 includes a bottom plate 101, a base frame 102, a threaded docking interface 103, a lifting column 104 and a sliding rod 105. The surface of the bottom plate 101 is fixedly connected to the base frame 102, the surface of the base frame 102 is fixedly provided with a threaded docking interface 103, the surface of the base frame 102 is fixedly connected to the lifting column 104, and the surface of the base frame 102 is fixedly connected to the sliding rod 105; the heating frame 2 includes a square frame 201, a connector 202 and a connecting line 203. The connector 202 is fixedly provided on one side surface of the square frame 201, the surface of the connector 202 is fixedly connected to the connecting line 203, and the square frame 201 is fixedly docked to the inner surface of the base frame 102; the mold top cover 3 includes a top cover frame 301, a sliding hole 302, a fixing hole 303, an injection hole 304 and a threaded docking interface 205. The surface of the top cover frame 301 is fixedly provided with a sliding hole 302, and the surface of the top cover frame 301 A fixing hole 303 is fixedly provided, an injection hole 304 is fixedly provided on the surface of the top cover frame 301, and a threaded docking interface 305 is fixedly provided on the surface of the top cover frame 301; the heating structure 4 includes a heating rod 401, a limiting ring 402, a fixed threaded cap 403, a connecting head 404 and a connecting line 405; a limiting ring 402 is fixedly provided on the surface of the heating rod 401, a fixed threaded cap 403 is movably sleeved on the surface of the limiting ring 402, a connecting head 404 is fixedly provided on one end surface of the heating rod 401, and a connecting line 405 is fixedly connected to one end surface of the connecting head 404; the fixing hole 303 of the mold top cover 3 is docked and installed with the lifting column 104 of the mold base 1, the sliding rod 105 is movably inserted with the sliding hole 302 of the mold top cover 3, the heating rod 401 of the heating structure 4 is docked and inserted with the threaded docking interface 1 103, and the fixed threaded cap 403 is spirally fixed with the threaded docking interface 1 103. The base frame 102 is provided with a notch with an opening facing upward at the position corresponding to the connecting line 1 203, so that the heating frame can fall completely into the base frame without affecting the connecting line 1 203. The top of the heating frame can be provided with a square groove with an opening facing upward, and the bottom of the heating frame is provided with a square protrusion at the position corresponding to the square groove, and the square protrusion is inserted into the square groove, so that multiple heating frames can be stacked together for use. When multiple heating frames are stacked and used, a hot air inlet and outlet are opened on the mold top cover, so that the mold is heated by hot air, and the air flow in the mold is accelerated at the same time. In order to make the mold heated more evenly, the mold top cover is preferably provided with only one hot air inlet and outlet. When used, hot air is blown inward first, and after the pressure in the mold is increased to the first air pressure, the hot air in the mold is sucked out, and after the pressure in the mold is reduced to the second air pressure, hot air is blown into the mold again, so as to circulate. Thus, by using a higher air pressure, the hot air can reach the smaller mold structure, so that the temperature of each part of the mold is more uniform, and then the model in the mold is heated evenly. In order to prevent the hot air from directly blowing onto the top of the model in the mold and causing deformation of the top of the model, an air guide plate may be provided below the hot air inlet and outlet.The air guide plate rotates around the central axis of the hot gas inlet and outlet, and the distance from one side of the air guide plate to the central axis of the hot gas inlet and outlet is greater than the distance from the other side of the air guide plate to the central axis of the hot gas inlet and outlet, thus forming an eccentric wheel shape. The upper and lower surfaces of the air guide plate are provided with radially extending strip protrusions, and the strip protrusions are arranged at equal intervals and form a ring around the center of the air guide plate, thereby forming multiple air guide channels on the top of the air guide plate. There is a certain angle between the strip protrusions and the vertical plane. When the hot air enters the mold from the hot gas inlet and outlet, it will blow the air guide plate to rotate. The lengths of the two sides of the air guide plate are different, so that the air outlet point changes, and finally the wind is more uniform everywhere. When the hot air flows out of the hot gas inlet and outlet from the mold, it will also blow the air guide plate to rotate, so that the water vapor condensed on the air guide plate (if any) is thrown out instead of falling on the model.

[0022] It should be noted that the present invention is a mold with a built-in heating mechanism, which can be horizontally lifted and lowered by the lifting column 104 and the sliding rod 105 of the mold base 1 to make the mold stably docked with the mold top cover 3, and the square frame 201 of the heating frame 2 is attached to the inner wall of the base frame 102. When the mold is fixed inside, it can be connected to the existing power generation and heating equipment through the connecting line 1 203 for heating. The heating frame 2 is provided with a hollow cavity, and liquid metal is provided in the hollow cavity. The use of liquid metal can make the temperature around the mold rise evenly, so that it is heated evenly. The heating frame is preferably supported by a heat-conducting material. The heating frame is located on the side wall outside the hollow cavity and has a heating element embedded therein, and the heating element is connected to the connecting line 1 203. Thereby increasing the temperature of the liquid metal. The heating rod 401 of the heating structure 4 is docked and fixed in a row with the threaded docking interface 1 103 and the threaded docking interface 2 305, and then the top and bottom plate are heated. In addition, the heating frame 2 can completely wrap the mold and heat it up, thereby improving the heating efficiency.
