[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] Working principle: First, the transmission motor 7 is started to drive the displacement spur gear 8 to move the rack. Since the rack is positioned on the support frame 5, the displacement spur gear 8 can be driven to move on the rack, causing the displacement frame 6 to slide on the support frame 5 until the mounting seat 21 is adjusted above the mold;

[0048] The electric push rod 43 is started to push the push guide plate 44, and the push guide plate 44 is connected with the power transmission rod 42, so that the power transmission rod 42 is displaced inside the central shaft 38 until the power transmission rod 42 is engaged with the driving shaft B34. Then, the power motor 39 is started to drive the transmission spur gear 40 to shift the reduction spur gear 41 to drive the central shaft 38 to rotate. Under the connection between the central shaft 38 and the power transmission rod 42, the power transmission rod 42 follows the rotation of the central shaft 38, and drives the driving shaft B34 to rotate, so that the driving worm 35 shifts the driving worm wheel 36, thereby driving the adjusting shaft 32 to rotate. In cooperation with the connection between the adjusting shaft 32 and the adjusting screw 33, the adjusting screw 33 can be displaced inside the adjusting shaft 32, so that the mounting seat 21 is close to the mold.

[0049] After the height of the carrying seat 21 is adjusted, the electric push rod 43 is started to pull the power transmission rod 42 to move, so that the power transmission rod 42 is separated from the driving shaft B34 and is engaged with the driving shaft A28, and then the power motor 39 is started to drive the central shaft 38 to rotate, so that the driving shaft A28 rotates with the power transmission rod 42. Under the connection between the driving shaft A28 and the transmission worm 29, the transmission worm 29 can shift the matching worm gear 30 to drive the positioning shaft 19 to rotate, and cooperate with the connection between the positioning shaft 19 and the displacement slide 20, so that the displacement slide 20 can follow the positioning shaft 19 to drive the eccentric conduction plate 26 to rotate, so that the displacement of the eccentric conduction plate 26 in the guide groove 27 can push the movable clamping plate 24 to approach the mold under the limit of the linear slide 23, and finally clamp the mold between the movable clamping plate 24 and the fixed clamping plate 22. After clamping, the power transmission rod 42 is connected to the driving shaft B34 to lift the carrying seat 21.

[0050] The hydraulic cylinder 13 is started to push the assembly column 12, so that the sealing door 11 connected to the assembly column 12 is turned over under the support of the loading seat 10, and in conjunction with the setting of the linkage plate 14, during the turning process of the sealing door 11, the linkage plate 14 can be used to pull the linkage shaft 16 to drive the carrier plate 3 to move under the limit of the linear guide rail 2, and because the two linkage plates 14 are respectively connected to the two linkage shafts 16, when the carrier plate 3 slides, the other linkage plate 14 can be used to push another sealing door 11, so that the two sealing doors 11 are turned over at the same time, the blockage of the furnace cavity of the heat treatment furnace main body 1 is released, and the carrier plate 3 is moved out of the heat treatment furnace main body 1.

[0051] Then start the transmission motor 7 to drive the displacement frame 6 to slide toward the heat treatment furnace body 1, adjust the mold to correspond to the carrier plate 3, and then place the mold on the carrier plate 3, start the hydraulic cylinder 13 to pull the sealing door 11 to close, and seal the heat treatment furnace body 1, and then perform heat treatment on the mold through the heat treatment furnace body 1. After heat treatment, use the mold pick-up and placement assembly 9 to remove the mold from the carrier plate 3 and transfer it to other processes.
