[0023] As Figures 1-3 shown, a pencil sharpener housing injection molding device includes a heating base material extruder 1. A driving motor 2 is arranged in the middle of one side of the heating base material extruder 1. A cooling water storage tank 3 is arranged on the outer surface of the lower end of the heating base material extruder 1.

A radiator 5 is arranged on the outer surface of the front end of the fitting type refrigerating sheet 4. A dust-proof plate 6 is arranged on the outer surface of the front end of the radiator 5. An inner waterway concave die 7 and a limit rod 8 are arranged on the outer surface of the other side of the heating base material extruder 1. The limit rod 8 is located in the middle of the inner waterway concave die 7. An inner waterway convex die 9 is arranged on the outer wall of the limit rod 8. A support base 10 is arranged on the outer surface of one end of the limit rod 8. A hydraulic driver 11 is arranged in the middle of one side of the support base 10. A fixed double-channel connection valve 12 is arranged on the outer surface of the lower end of the inner waterway concave die 7. A movable double-channel connection valve 13 is arranged on the outer surface of the lower end of the inner waterway convex die 9. Mounting brackets 14 are arranged on the outer surface around the inner waterway concave die 7. A safety light curtain emitter 15 is arranged on the outer surface of one side of the mounting bracket 14. A monitor 17 is arranged in the middle of the upper end of the mounting bracket 14. A light curtain receiving frame 16 is arranged on the outer surface around the inner waterway convex die 9. A connection wire harness 18 is arranged in the middle of the upper end of the monitor 17. A start-stop controller 19 is arranged on the outer surface of one end of the connection wire harness 18.

[0024] It should be noted that the present utility model is an injection molding device for a pencil sharpener housing, which is provided with a heating type base material extruder 1, a driving motor 2, a cooling type water storage tank 3, a fitting type refrigerating sheet 4, a radiator 5, a dust-proof plate 6, an inner waterway concave mold 7, a limiting rod 8, an inner waterway convex mold 9, a support base 10, a hydraulic driver 11, a fixed double-channel connection valve 12, a movable double-channel connection valve 13, a mounting bracket 14, a safety light curtain emitter 15, a light curtain receiving frame 16, a monitor 17, a connection wire harness 18 and a start-stop controller 19. When in use, first, thermoplastic or thermosetting plastic is added to the heating type base material extruder 1 through a feeding component, and then the heating type base material extruder 1 heats and melts it. After melting, first, the hydraulic driver 11 in the middle of the support base 10 pushes the inner waterway convex mold 9. During the movement, the movement is limited by the limiting rod 8. Through the movement, the inner waterway convex mold 9 is combined with the inner waterway concave mold 7, and the fixed double-channel connection valve 12 and the movable double-channel connection valve 13 at the bottom are aligned and connected. During the movement, the safety light curtain emitter 15 on the mounting bracket 14 activates the safety light curtain.

When the monitor 17 on the mounting bracket 14 detects that the light curtain is blocked, the information is transmitted to the start-stop controller 19 through the connection wire harness 18. Then, the start-stop controller 19 controls the hydraulic driver 11 in the support base 10 to stop working, avoiding external objects from intervening between the inner waterway concave mold 7 and the inner waterway convex mold 9. When no object intervention is detected, the driving motor 2 drives the screw extrusion rod inside the heating type base material extruder 1. The heating type base material extruder 1 injects the liquid plastic raw material between the inner waterway concave mold 7 and the inner waterway convex mold 9. After injection, the water supply motor inside the cooling type water storage tank 3 transfers the cooling water inside it to the inside of the inner waterway concave mold 7 and the inner waterway convex mold 9 through the fixed double-channel connection valve 12 and the movable double-channel connection valve 13. The cooling water that has completed heat exchange flows back to the cooling type water storage tank 3 and is quickly cooled by the fitting type refrigerating sheet 4. The heat generated by the work of the fitting type refrigerating sheet 4 is blown away by the radiator 5. By using the cooling water, the liquid raw material can be cooled to quickly solidify it. After solidification, the hydraulic driver 11 can drive the inner waterway concave mold 7 and the inner waterway convex mold 9 to separate, completing the unloading work of the pencil sharpener housing. When in use, first, safety light curtain protection is carried out during the merging process of the injection mold. When an external object intervenes, the equipment is promptly controlled to stop working, avoiding production accidents and thus avoiding personal injuries and equipment damage. At the same time, during use, the mold and the product can be quickly cooled through the heat exchange work of the circulation of low-temperature cooling water, avoiding sticking of the injection molded housing, thereby improving the production quality and production efficiency of the pencil sharpener housing.
