[0018] Embodiment: As Figures 1-5As shown in the figure, the utility model provides a hot melting device for plastic processing, including a base 1. Above the base 1, there is a top plate 12. A lifting rod 14 is slidably inserted into the top plate 12. At the top of the lifting rod 14, there is a hydraulic cylinder 13. The driving end of the hydraulic cylinder 13 is fixedly installed coaxially with the lifting rod 14. At the bottom end of the lifting rod 14, there is a fixedly installed mounting plate 15. At the bottom end of the mounting plate 15, there is a hot melting mold 16. Above the base 1, there is a moving seat 17. At the top of the moving seat 17, there is a fixedly installed processing base 18. Inside the processing base 18, symmetrically distributed screws 2 are rotatably arranged. Symmetrically distributed moving blocks 21 are threadedly sleeved on the outer parts of the screws 2. The moving blocks 21 are slidably arranged inside the processing base 18. At the top of the moving blocks 21, there are fixedly installed clamping blocks 22.

[0019] At the four corners of the mounting plate 15, sliding rods 33 are slidably inserted. The top ends of the sliding rods 33 are fixedly installed with the bottom end of the top plate 12. The bottom ends of the sliding rods 33 are fixedly installed with the top end of the base 1. Buffer seats 3 are slidably sleeved on the outer parts of the sliding rods 33. Springs 32 are arranged on the outer parts of the sliding rods 33. The top ends of the springs 32 are fixedly installed with the inner upper surface of the buffer seats 3. The bottom ends of the springs 32 are fixedly installed with the top end of the base 1. A fixed seat 31 is slidably sleeved on the outer part of the buffer seat 3. The bottom end of the fixed seat 31 is fixedly installed with the top end of the base 1.

[0020] On one side outer wall of the processing base 18, there is a fixedly installed housing 200. At one end of each screw 2, there is a fixedly installed connecting rod 210. One end of the connecting rod 210 rotates through one side wall of the base 1 and is placed inside the housing 200. At the end of the connecting rod 210 far from the screw 2, there is a fixedly installed worm gear 220. On one side of each worm gear 220, there is a meshing worm 230.

[0021] Between the worms 230, there is a fixedly installed transmission rod 240. At one end of one of the worms 230 far from the transmission rod 240, there is a fixedly installed driving rod 250. The end of the driving rod 250 far from the worm 230 rotates through one side wall of the housing 200 and is placed outside.

[0022] At the end of the driving rod 250 far from the worm 230, there is a motor 260. The driving end of the motor 260 is fixedly installed coaxially with the driving rod 250.

[0023] A limiting member 270 is rotatably sleeved on the outer part of the transmission rod 240. The bottom end of the limiting member 270 is fixedly installed with the inner wall of the housing 200; by setting the limiting member 270, the effect of limiting the transmission rod 240 is achieved, so that the transmission rod 240 can rotate stably.

[0024] At the bottom ends of the buffer seats 3, stabilizing rods 310 distributed in an annular array are slidably inserted. The bottom ends of the stabilizing rods 310 are fixedly installed on the bottom end of the base 1, and the top ends of the stabilizing rods 310 are fixedly installed on the inner upper surface of the fixed seat 31. By providing the stabilizing rods 310, the effect of limiting the buffer seats 3 is achieved.

[0025] At the bottom ends of the moving blocks 21, guiding blocks 280 are fixedly provided. In the guiding blocks 280, guiding rods 290 are slidably inserted. Both ends of the guiding rods 290 are fixedly installed on the inner wall of the processing base 18. By providing the guiding blocks 280 and the guiding rods 290, the effect of limiting the moving blocks 21 is achieved, enabling the moving blocks 21 to move stably.

[0026] Working principle: First, place the workpiece to be hot-melt processed on the processing base 18, start the motor 260 to drive the driving rod 250 to rotate. The driving rod 250 drives the worm wheel 220 to rotate through the worm 230 and the transmission rod 240. The worm wheel 220 drives the screw rod 2 to rotate through the connecting rod 210. During the rotation of the screw rod 2, the moving blocks 21 are driven to move towards each other. The moving blocks 21 drive the clamping blocks 22 to move towards each other. When the clamping blocks 22 move to a position where they are in close contact with the workpiece, turn off the motor 260 to complete the fixation of the workpiece. Subsequently, drive the lifting rod 14 to move downward by driving the hydraulic cylinder 13. The lifting rod 14 drives the hot-melt mold 16 to move downward through the mounting plate 15. During the downward movement of the mounting plate 15, it slides upward on the sliding rod 33. When the mounting plate 15 moves to a position where it contacts the buffer seat 3, the buffer seat 3 moves downward under the pressure of the mounting plate 15. During the downward movement of the buffer seat 3, the spring 32 is compressed and deformed, thereby buffering the hot-melt mold 16 and preventing the impact force during the descent of the hot-melt mold 16 from damaging the hot-melt mold 16, the processing base 18, and the workpiece.

[0027] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these modifications and variations.
