The elevating block 31 connected to the screw shaft 30 by the screw thread is moved downward, the elevating block 31 is moved downward to move the holding block 32 downward, and the inner wall of the mold 34 is on the upper end surface of the screw sleeve 38. It comes to abut, pushes the screw sleeve 38 to move downward, rotates the first screw shaft 50 connected to the screw sleeve 38 by the thread, and further rotates the rotation rod 52, and the rotation rod 52 rotates. Then the two rotary gears 44 are rotated, the two rotary gears 44 are rotated, one of the two rotary gears 44 is moving the lower rack 46 to the right, and the other is the upper rack 46. When it is moved to the left and the two scrapers 45 on the two racks 46 hit the inner wall of the mold 34, and the two scrapers 45 hit the side inner wall of the mold 34, the two racks 46 are stopped. The two rotary gears 44 stop rotating and spin freely on the rotating rod 52, and the screw sleeve 38 hits the lower inner wall of the compression space 49 when it moves downward to the bottom inside the compression space 49. The downward movement is stopped, the holding block 32 moves downward, and the mold 34 is gradually lowered.
When scraping off unnecessary plastic adhering to the inner wall of the mold 34, the rotating block 51 rotates to rotate the two racks 46 and the two scrapers 45, and further by the rotation of the two scrapers 45 and the lowering of the mold 34. The unnecessary plastic adhering to the inner wall of the mold 34 is scraped off, the scraped unnecessary plastic falls into the push plate space 12, and the rotating block 19 rotates to rotate the two fixing rods 17 and the two push plates 11. The push plate 11 was rotated to push the unnecessary plastic that had fallen into the push plate space 12 into the punch hole 16, and the unnecessary plastic was finally dropped into the collection space 15 to be collected and scraped off. After that, the motor 22 is stopped, the screw sleeve 38 moves upward by the elastic force action of the elastic spring 47 and returns, and the two racks 46 and the two scrapers 45 return by the action of the two tension springs 40, and three The tightening bolt 35 is turned in the opposite direction, the mold 34 is taken out from the holding space 33, the motor 22 is started and reversed, and is transported upward to return the elevating block 31 and the holding block 32 by mechanical transmission, and the motor 22. And finish the operation.

The above-mentioned examples merely explain the technical concept and features of the present invention , the purpose of which is to make a person skilled in the art understand the contents of the present invention and further implement the invention, and the scope of protection of the present invention cannot be limited. .. All equivalent changes or modifications were made on the basis of the real spirit of the invention should contain in the protection scope of the present invention.
