[0023] The residual material removal assembly for scraping off overflow includes a first lead screw 101 rotatably connected to the outside of the telescopic end of the hydraulic cylinder 3. A movable ring 102 is threadedly connected to the outside of the first lead screw 101. Two sets of scrapers 103 are symmetrically and movably connected to one side of the pressure plate 4. A connecting rod 104 is symmetrically hinged between the scraper 103 and the movable ring 102 through a hinge. A guide rod is also fixedly connected to the outside of the telescopic end of the hydraulic cylinder 3, and the guide rod is slidably connected to the movable ring 102, which can guide the movement of the movable ring 102. Two sets of T-shaped limit blocks 105 are symmetrically fixedly connected to one side of the scraper 103. A T-shaped limit groove is opened on the pressure plate 4 at the position corresponding to the T-shaped limit block 105, and the T-shaped limit groove is slidably connected to the T-shaped limit block 105 on the same side, which can guide the movement of the scraper 103. A notch is opened on the scraper 103 at the position corresponding to the telescopic end of the hydraulic cylinder 3.

[0024] A residual material collection assembly for collecting scraped overflow includes a collection trough 209 on a base 1, a cover plate 201 on the top of the collection trough 209, a push plate 202 fixedly connected to one side of the cover plate 201, and two sets of fixing rods 203 symmetrically fixedly connected to the other side of the cover plate 201 relative to the push plate 202. The ends of the two sets of fixing rods 203 are fixedly connected to the same first magnet 204. A second magnet 205 is fixedly connected to one side of the top of the base 1. The top of the base 1 is symmetrically fixedly connected to... Two sets of connecting seats are connected and the connecting seats are slidably connected to the fixed rod 203 on the same side. A spring 206 is sleeved on the outside of the fixed rod 203. A push frame 207 is fixedly connected to the bottom of the telescopic end of the hydraulic cylinder 3. A U-shaped connecting frame 208 is fixedly connected to the push plate 202. A collection drawer is movably set inside the collection tank 209 to facilitate the collection of scraped overflow. The magnetic poles of the first magnet block 204 and the second magnet block 205 are set in opposite directions. The two ends of the spring 206 are fixedly connected to the connecting seat and the cover plate 201 respectively.

[0025] The implementation principle of a plastic board extrusion molding machine in this application embodiment is as follows: First, the hydraulic cylinder 3 pushes the pressure plate 4 to move into the mold 2. When the hydraulic cylinder 3 pushes the pressure plate 4 to move into the mold 2, it can also drive the push frame 207 to move together. When the push frame 207 moves to contact the push plate 202, it can drive the cover plate 201 fixedly connected to the push plate 202 to move together, thereby opening the collection groove 209. Since there is a sliding fit between the fixed rod 203 and the connecting seat, the spring 206 will be compressed at this time. Then, the hot melt raw material is added into the mold 2 through the feeding port, and then the sealing cover is used to seal the mold. The feeding port is sealed, and then the hydraulic cylinder 3 continues to push the pressure plate 4 to extrude the hot-melt raw material. At this time, the pusher 207 will push the cover plate 201 to continue moving. When the pressure plate 4 stops moving, the first magnet 204 and the second magnet 205 are attracted together. After extrusion, the first lead screw 101 is rotated. The threaded connection between the first lead screw 101 and the moving ring 102, and the sliding connection between the moving ring 102 and the guide rod, enable the moving ring 102 to move. The hinge between the moving ring 102, the scraper 103, and the connecting rod 104 is used to... With the sliding engagement between the T-shaped limiting block 105 and the T-shaped limiting groove, the two sets of scrapers 103 can be pushed to move simultaneously to both sides when the moving ring 102 moves, thereby scraping off the overflow generated during the extrusion molding of the plastic board, thus ensuring the quality of the plastic board extrusion molding. After scraping is completed, the first lead screw 101 is reversed to drive the scraper 103 to reset, and then the hydraulic cylinder 3 is activated to drive the pressure plate 4 to reset. The scraped overflow will be carried out of the mold 2 and fall into the collection tank 209. When the push frame 207 contacts the U-shaped connecting frame 208, as the extension end of the hydraulic cylinder 3 continues to retract, This allows the first magnet block 204 to separate from the second magnet block 205. At this time, under the rebound action of the spring 206, the cover plate 201 can automatically reset to close the collection groove 209. When the cover plate 201 returns to its original position, the push plate 202 can push the overflow material that has fallen on the base 1 into the collection groove 209, thereby achieving the purpose of thoroughly collecting the overflow material generated during the extrusion molding of the plastic board. By closing the collection groove 209 with the cover plate 201, dust can be prevented from entering and affecting the subsequent use of the plastic board material. Finally, the extruded plastic board can be taken out from the mold 2.

[0026] Furthermore, a further improvement is made in that: a movable plate 5 is provided inside the mold 2, and a second lead screw 6 is rotatably connected to one side of the movable plate 5 and the second lead screw 6 is threadedly connected to the mold 2. Two sets of limiting rods 7 are symmetrically fixedly connected to one side of the movable plate 5 and the limiting rods 7 are slidably connected to the mold 2, which can guide the movement of the movable plate 5. By rotating the second lead screw 6, the movable plate 5 can be moved, so that the molded plastic board can be pushed out of the mold 2, thus making it convenient to pick up the plastic board.
