The second gear 752 is meshed with the first gear 741, and the height of the first gear 741 is flush with the middle position of the second gear 752. The height of the second tooth 743 is lower than the lowest point of the second gear 752.

[0030] Reference Figure 2 , Figure 3 , Figure 6 , Figure 7 and Fig. 9As shown, when the device is used, the material is first placed on the top of the heating base 3, and then the heating plate 4 is started to heat the material. When it is heated to a certain temperature, the servo motor 73 is controlled to rotate to drive the third gear 76 to rotate synchronously, so that the toothed disc 74 meshing with it rotates clockwise. After the first tooth 742 of its inner wall contacts the second gear 752, it continues to rotate to drive the support cylinder 75 and the suction cup 71 to rotate 90° to one side.

After the suction cup 71 releases the material and places it inside the lower mold 2, the second tooth 743 rotates away from the first gear 741, and the third tooth 744 contacts the second gear 752, driving the support cylinder 75 and the suction cup 71 to rotate and reset to the middle position between the lower mold 2 and the heating base 3. The servo motor 73 can complete the material conversion position every time it rotates one circle. When the material leaves the interior of the heating base 3, the new material can be placed in the heating base 3 for heating, saving processing time.

[0031] An upper mold 22 is arranged on the top of the lower mold 2, and a cylinder 21 is installed on the top of the upper mold 22. Guide shafts 23 are arranged at the corners of the upper mold 22. The top and bottom ends of the guide shafts 23 are respectively fixed to the upper mold 22 and the workbench 1, and a sliding structure is formed between the upper mold 22 and the guide shafts 23. Buffer seats 24 are installed at the corners of the top of the lower mold 2, and buffer tubes 25 are installed at the bottom of the upper mold 22 on the top of the buffer seats 24. Piston columns 254 are installed inside the buffer tubes 25, and springs 255 are arranged on the tops of the piston columns 254. The piston columns 254 and the buffer tubes 254 are connected to the buffer tubes 254. 5 constitute a sliding structure, the inner wall of the buffer tube 25 is provided with a chamber 252, and the top of the chamber 252 is provided with an inlet hole 251, and the bottom of the chamber 252 is provided with a reflux hole 253, a piston plate 63 is provided inside the cavity 6, and a connecting rod 61 is installed on the top of the piston plate 63, the top of the connecting rod 61 is fixed to the side wall of the upper mold 22, one end of one side of the cavity 6 is connected to a tube body 64, and the end of the tube body 64 away from the cavity 6 is connected to the side wall of the lower mold 2, and the other end of one side of the cavity 6 is connected to a hose 62, and the end of the hose 62 away from the cavity 6 is connected to the side wall of the upper mold 22;

[0032] Reference Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, when the device is used, after the material is placed on the top of the lower mold 2, the cylinder 21 is started to drive the upper mold 22 to move downward to press the material. When the upper mold 22 moves downward, the piston plate 63 is driven to move inside the cavity 6 through the connecting rod 61. The bottom of the cavity 6 is provided with a hole body, and the corners of the pressing position of the upper mold 22 and the lower mold 2 are provided with air holes. When the piston plate 63 presses down, gas is discharged from the hole body, and the air holes at the top corners of the lower mold 2 generate suction through the tube body 64, which can have a certain adsorption effect on the material, effectively maintain its flatness during the pressing process, and ensure the pressing effect. A one-way valve that can only vent air is installed at one end of the bracket 72, so that when the piston plate 63 is pressed down, the air holes at the bottom of the upper mold 22 do not generate suction, the upper mold 22 continues to press down, and the piston column 254 The bottom contacts the buffer seat 24 first, and the piston column 254 is lifted and moved upward by continuous downward pressure. Hydraulic oil is arranged inside the buffer tube 25. The hydraulic oil is squeezed and flows from the inlet hole 251 to the chamber 252, and then flows from the reflux hole 253 to the bottom of the piston column 254, so as to play a buffering effect when the upper mold 22 is pressed down, avoiding excessive collision during downward pressure and damage to the device. After the pressing work is completed, the cylinder 21 controls the upper mold 22 to move upward, driving the piston plate 63 to move synchronously, so that the gas at the top of the cavity 6 is squeezed and enters the interior of the upper mold 22 and the lower mold 2 respectively through the hose 62 and the tube body 64. The air hole is connected with the hose 62 and the tube body 64, and the gas is discharged through the air hole. Blowing helps demoulding to avoid sticking to the upper mold 22 when the material is too thin, which is convenient for the staff to take the material.
