The air pump 7 of this structure can be driven to transport the dry ice particles inside the container 6 from the hose 8 to the nozzle 9, and the nozzle 9 can be installed on the mounting block 12 to spray the dry ice particles onto the surface of the bottom mold 2, so as to quickly freeze the colloidal residue through the physical sublimation effect of dry ice. The method is efficient and environmentally friendly, does not damage the surface of the bottom mold 2, and has no chemical residue, which greatly improves production efficiency and ensures the quality of the product. When the cylinder 10 is driven, it can drive the mounting block 12 to move laterally at the front end of the swing plate 11. When the mounting block 12 moves laterally, it can drive the nozzle 9 to spray the dry ice particles more evenly onto the surface of the bottom mold 2, thereby achieving a more effective rubber powder removal effect. The front end of the mounting block 12 is provided with an elastic buckle 13 of an arc-shaped structure. The elastic buckle 13 is made of an existing thin metal material, and the front side of the elastic buckle 13 is an open structure. The nozzle 9 of this structure is quickly installed on the mounting block 12 by squeezing it inside the elastic buckle 13, which is more convenient to use. The back side of the mounting block 12 is welded and fixed with a guide The guide block 18 is provided on the front wall of the swing plate 11, and a guide groove matching with the guide block 18 is provided. The mounting block 12 of this structure can drive the guide block 18 to slide along the guide groove on the front wall of the swing plate 11 when it is displaced laterally, so as to improve the stability during lateral displacement, and the guide block 18 also plays a role of limiting the mounting block 12. The front end of the lifting seat 4 is located on both sides of the swing plate 11 and is provided with a solid block 14. The inner side of the solid block 14 is welded and fixed to the outer wall of the front end of the lifting seat 4, and a vertical opening is provided on the solid block 14. A push rod 16 is horizontally inserted in the vertical opening on the solid block 14, and a coupling 15 is connected between one end of the push rod 16 located on the inner side of the solid block 14 and the side wall of the front end of the swing plate 11. The connection between the two ends of the coupling 15 and the push rod 16 and the swing plate 11 is hinged by a rotating pin.The push rod 16 of this structure can pull the coupling 15 by pushing the vertical opening on the solid block 14. When the coupling 15 moves, it will produce a linkage with the outer end of the swing plate 11, so as to achieve the function of adjusting the up and down inclination of the outer end of the swing plate 11, so that the swing plate 11 can adjust the nozzle 9 to a more suitable spraying angle through the mounting block 12, ensuring the effect of the nozzle 9 spraying on the surface of the bottom mold 2.

[0018] Working principle: When using the injection mold structure for preventing the residual rubber powder, first, when the hydraulic cylinder on the top of the top seat 3 drives the lifting seat 4 to lift and lower so that the bottom mold 2 and the top mold 5 are molded together, the nozzle 9 is first quickly installed on the mounting block 12 by squeezing it inside the elastic buckle 13, and then the angle of the nozzle 9 facing the bottom mold 2 is controlled by adjusting the inclination angle of the front end of the swing plate 11. At this time, the two push rods 16 are first pushed synchronously to move in the vertical opening on the solid block 14. When the push rods 16 move to different vertical positions, they will pull the coupling 15. When the coupling 15 moves, it will generate linkage with the outer end of the swing plate 11 until the outer end of the swing plate 11 tilts up and down to a suitable angle, and then the inner end of the screw pin 17 is fixed in the corresponding threaded hole on the solid block 14. , so as to limit the push rod 16 so that the adjusted position of the swing plate 11 is also locked. When the lifting seat 4 drives the top mold 5 to descend to a suitable position, the air pump 7 is started. The air pump 7 transports the dry ice particles inside the container 6 from the hose 8 to the nozzle 9. The nozzle 9 can spray the dry ice particles onto the surface of the bottom mold 2, so as to quickly freeze and embrittle the gelatinous residue through the physical sublimation effect of the dry ice, so as to quickly remove the glue powder attached to the surface of the bottom mold 2. At the same time, the cylinder 10 is started. When the cylinder 10 is driven, it will drive the mounting block 12 to move horizontally at the front end of the swing plate 11. When the mounting block 12 moves horizontally, it can drive the nozzle 9 to spray the dry ice particles onto the surface of the bottom mold 2 more evenly, so as to achieve a more effective glue powder removal effect, thereby completing a series of tasks.
