When in use, the staff starts the extruder 2, and after the extruder 2 performs injection molding on the inside of the left mold 14 and the right mold 15, the staff starts the first motor 4, and the first motor 4 drives the rotating shaft 5 to rotate. The rotating rod 7 is arranged on the side away from the rotating plate 6, so that the rotating shaft 5 can drive the rotating rod 7 to rotate eccentrically through the rotating plate 6, and the transmission plate 8 and the fan-shaped plate 11 are driven to rotate reciprocatingly through the rotating rod 7, and the knocking ball 13 can knock the left mold 14 to a certain extent. At the same time, the knocking of the knocking ball 13 on the left mold 14 causes the solution inside the left mold 14 to vibrate to a certain extent, and the material inside the molding chamber of the left mold 14 is squeezed more tightly, which reduces the occurrence of bubbles in the material inside the molding chamber of the left mold 14 to a certain extent, and ensures the molding quality of the workpiece to a certain extent; The staff starts the cylinder 16 to move the left mold 14 away from the right mold 15 and realize the mold opening of the device. At the same time, the molded mold can be discharged from the left mold 14 and the right mold 15 through the ejector in the prior art mold. The two discharged workpieces fall on the material transfer plate 56 through the guide of the receiving plate 22. The staff starts the second motor 24, and the second motor 24 drives the second transmission shaft 30 to rotate through the active transmission wheel 27 and the first belt 26. The second transmission shaft 30 drives the third transmission shaft 31 to rotate through the third transmission wheel 32 and the third belt 33. The third transmission shaft 31 drives the transmission rod 57 to rotate through the second belt 29 and the first driven transmission wheel 28, so that the two workpieces falling on the material transfer plate 56 are blocked by the transmission roller 36. The workpiece is adjusted to be parallel to the axial direction of the transmission roller 36 under the inclined setting of the material transfer plate 56. When the workpiece is parallel to the axial direction of the transmission roller 36, the friction between the workpiece and the transmission roller 36 is maximized, so that the transmission roller 36 drives the workpiece to move to the second screening roller 35. Through the restriction of the diverter plate 37, when the workpiece coincides with the screening groove on the second screening roller 35, the workpiece falls on the first guide plate 38 through the screening groove on the second screening roller 35. The workpiece larger than the screening groove on the second screening roller 35 moves to the first screening roller 34 under the drive of the second screening roller 35, falls on the second guide plate 40 through the screening groove of the first screening roller 34, and through the inclined setting of the first guide plate 38 and the second guide plate 40, the workpiece is classified and falls on both sides of the rotating screen plate 41, and the classified collection of the workpiece is realized; When the workpiece falls on the top of the rotating sieve plate 41, the second motor 24 drives the first transmission shaft 25 to rotate, and the cam 53 is driven to rotate through the first transmission shaft 25, so that the rotating sieve plate 41 can be rotated up and down, and at the same time, the rotating sieve plate 41 is rotated upward, so that the gear 46 rotates with the cooperation of the arc groove 45, and at the same time, the cross-section of the trapezoidal groove 48 is trapezoidal, so that the right angle surface of the trapezoidal groove 48 blocks the positioning rod 49, so that the gear 46 can drive the power shaft 47 to rotate, and after the workpiece slides to the top of the blocking rod 55 under the action of gravity, the power shaft 47 drives the workpiece to flip and move downward through the turning rack 44, so that the workpiece can be more evenly in contact with the air, and the cooling speed of the workpiece is accelerated, so that the workpiece can be cooled more smoothly, and the cooled workpiece is discharged from the inside of the discharge chute 54 to the inside of the collection box 19 for classification and collection; At the same time, the cross-section of the trapezoidal groove 48 is a trapezoid. When the gear 46 moves downward, the inclined surface of the trapezoidal groove 48 pushes the positioning rod 49 to slide out of the interior of the trapezoidal groove 48, and the gear 46 cannot drive the power shaft 47 to rotate, thereby preventing the tipping rack 44 from rotating in the opposite direction to squeeze the workpiece and causing the device to get stuck, and at the same time allowing the device to run more smoothly.
