[0037] Working principle: When using, first select the required mold ring according to the size to be processed. When the No. 2 mold ring 55 is needed, the No. 1 mold ring 53 can be driven down by multiple electric telescopic rods 54 so that its top is flush with the circular plate 51. When the No. 3 mold ring 56 is needed, the No. 2 mold ring 55 is driven down by multiple electric telescopic rods 54 so that its top is flush with the circular plate 51 and the top of the No. 1 mold ring 53. When the molding assembly 5 is adjusted, adjust it according to the size of the mold. The pressing assembly 3 is adjusted. When the No. 2 mold ring 55 is used, the No. 1 adjusting ring 35 is rotated to move it downward along the screw 32, so that the bottom surface of the No. 1 pressing ring 34 is flush with the bottom surface of the pressing block 33. When the No. 3 mold ring 56 is needed, the No. 2 adjusting ring 37 is rotated to move it downward along the No. 1 adjusting ring 35, so that the bottom surface of the No. 2 pressing ring 36 is flush with the bottom surfaces of the pressing block 33 and the No. 1 pressing ring 34. Then, the driving push rod is turned on to perform hot pressing on the rubber in the molding assembly 5.

[0038] After the product is formed, the pressing component 3 will withdraw from the interior of the forming component 5, and then the cylinder 52 will be turned on. The cylinder 52 will push the circular plate 51 upward to push the product out of the forming component 5, and the motor 61 will drive the rotating shaft 62 to rotate, and the rotating plate 63 connected thereto will rotate accordingly, thereby driving the lever 64 to move, thereby driving the connecting ring 66 to move, and the sliding rod 67 connected thereto will slide on the inner wall of the limit block 65. Due to the limiting effect of the limit block 65, the sliding rod 67 can only move forward and backward. The sliding rod 67 located on the rear side will push the product pushed out by the circular plate 51 to move to the material guide trough 11. After the product falls into the material guide trough 11, it will be sent to the collection box.
