First, the triangular plate 5708 contacts the molded foam plastic product. The guide plate 5709 prevents the foam product from falling from the front and rear sides of the triangular plate 5708, and the movement of the fixed plate 3 5707 drives the foam product to move. Then, when the triangular plate 5708 moves to the top of the triangular block 43, , under the action of the hinge between the fixed plate three 5707 and the dovetail groove 5706, the triangular plate 5708 will tilt with the inclined surface of the triangular block 43, so that the molded foam plastic product falls into the interior of the storage box 3 under the limit of the U-shaped limit frame 2. At the same time, when the cleaning brush 5704 moves to the top of the lower mold 447, the stepper motor three 5702 is started, and the rotating rod 570 is driven to rotate through the rotating shaft 5701, thereby driving the cleaning brush 5704 to rotate at high speed, and then the stepper motor two 575 is started, and the rotating shaft one 574 drives the threaded rod two 576 to rotate, thereby driving the slider two 577 to move along the axial direction of the threaded rod two 576, so that the L-shaped block 578 and the cleaning brush 5704 connected thereto can move back and forth. This combination of rotation and linear movement makes the cleaning process more efficient and thorough, so that the device can remove foam debris or impurities remaining on the surface of the mold, ensuring the cleanliness of the mold and the smoothness of the next use.

[0037] Working principle of the present invention: First, the raw materials in the material storage box 10 are accurately injected into the top of the lower mold with the help of the hose 102, the connecting sleeve 104 and the electric push rod 105. The pneumatic push rod 106 is started to push the upper mold 107 to move downward. According to the need, it stays above the lower mold 447 and fits with the inner wall of the mold groove 41. With the injection of raw materials and the closing of the mold, the molding process of the foam plastic product officially begins. When the foam plastic product is formed, by starting the stepper motor 450, its rotational power is first transmitted to the two gears 458 through the fixed rod 459. Due to the meshing relationship between the gear 458 and the tooth plate 451, the tooth plate 451 will rotate The rotational force is converted into linear motion, pushing the L-shaped plate 445 to slide forward along the guide groove 17. As the L-shaped plate 445 moves forward, it pushes the connecting rod 446, thereby driving the lower mold 447 to slowly rise along the inner wall of the mold groove 41. In this process, when the gear 458 rotates to the outer wall of the tooth 457, it will drive the two movable sleeves 455 to slide on the outer wall of the slide rod 453 and squeeze the spring 454. The spring 454 is reset through the teeth of the gear 458, and then the stepper motor 450 will continue to output to rotate the fixed rod 459, and the foam plastic product will be completely removed from the mold, and at the same time drive the cleaning structure 5 to start working.

[0038] The fixed rod 459 continuously rotates, thereby driving the conical tooth 1 4501 to rotate and then the conical tooth 2 4502 to rotate. The conical tooth 2 4502 rotates and drives the fixed rod 2 4503 to rotate the conical tooth 3 4505. The meshing transmission of the conical tooth 3 4505 and the conical tooth 4 53 converts it into the rotational motion of the threaded rod 1 52. As the threaded rod 1 52 rotates, the slider 1 54 threadedly connected thereto begins to move along its axial direction and drives the cleaning assembly 57 to move. At the same time, the sliding of the sleeve 56 on the slider 2 55 ensures the stable movement of the cleaning assembly 57 in the horizontal direction. First, the triangular plate 5708 contacts the molded foam plastic product. The guide plate 5709 prevents the foam product from falling from the front and rear sides of the triangular plate 5708, and the movement of the fixed plate 3 5707 drives the foam product to move. Then, when the triangular plate 5708 moves to the top of the triangular block 43, , under the action of the hinge between the fixed plate three 5707 and the dovetail groove 5706, the triangular plate 5708 will tilt with the inclined surface of the triangular block 43, so that the molded foam plastic product falls into the interior of the storage box 3 under the limit of the U-shaped limit frame 2. At the same time, when the cleaning brush 5704 moves to the top of the lower mold 447, the stepper motor three 5702 is started, and the rotating rod 570 is driven to rotate through the rotating shaft 5701, thereby driving the cleaning brush 5704 to rotate at high speed, and then the stepper motor two 575 is started, and the rotating shaft one 574 drives the threaded rod two 576 to rotate, thereby driving the slider two 577 to move along the axial direction of the threaded rod two 576, so that the L-shaped block 578 and the cleaning brush 5704 connected thereto can move back and forth. This combination of rotation and linear movement makes the cleaning process more efficient and thorough, so that the device can remove foam debris or impurities remaining on the surface of the mold, ensuring the cleanliness of the mold and the smoothness of the next use.
