The demolding auxiliary component 2 includes a discharge hopper 20 disposed directly below the molding die 10. Two symmetrical side plates 23 are fixedly installed on the front side of the bottom plate of the discharge hopper 20. A first conveyor belt 241 is disposed between the two side plates 23. The first conveyor belt 241 and the side plates 23 pass through the discharge hole 12, so that as the first conveyor belt 241 rotates, the demolded plastic parts that fall onto the first conveyor belt 241 can be conveyed outward, so as to facilitate unloading.

[0026] Specifically, a second conveyor belt 261 is provided at the unloading end of the first conveyor belt 241. The second conveyor belt 261 is located below the first conveyor belt 241, so as to further transport the plastic parts outward to the corresponding position for unloading.

[0027] Specifically, a material feeding assembly 27 is provided between the two side plates 23. The material feeding assembly 27 includes a long shaft 271 rotatably connected between the two side plates 23. A material feeding cylinder 273 is rotatably connected to the long shaft 271. After the high-profile component is conveyed to the material feeding cylinder 273 by the first conveyor belt 241, the material feeding cylinder 273 can knock down the plastic part, so that the plastic part can be conveyed outward from the discharge hole 12 more smoothly.

[0028] In this embodiment, a plurality of heat dissipation holes 11 are provided on the front side plate of the injection molding machine body 1, and the heat dissipation holes 11 are used for heat dissipation operation; a support pad 13 is fixedly installed at the bottom of the injection molding machine body 1, and the support pad 13 is used for support operation.

[0029] Specifically, a rubber buffer pad 21 is provided on the upper surface of the bottom plate of the unloading hopper 20. The rubber buffer pad 21 is used for buffer protection to prevent the plastic parts from being damaged. Two symmetrical support plates 22 are fixedly installed between the unloading hopper 20 and the bottom wall of the injection molding machine body 1. The support plates 22 provide support.

[0030] Furthermore, a first rotating shaft 24 is rotatably connected between the two side plates 23 and between the two support plates 22. A first conveyor belt 241 is fitted onto the two first rotating shafts 24. A first drive motor 242 is coaxially mounted at the end of one of the first rotating shafts 24. Two mutually symmetrical second rotating shafts 26 are mounted on the second conveyor belt 261. The second conveyor belt 261 is fitted onto the two second rotating shafts 26. A second drive motor 262 is coaxially mounted at the end of one of the second rotating shafts 26. Both the second rotating shafts 26 and the second drive motor 262 are mounted on the external frame. The second rotating shafts 26 are rotatably connected to the external frame, enabling the first conveyor belt 241 and the second conveyor belt 261 to rotate normally.

[0031] In addition, a top plate 25 is fixedly installed on the top plate of the two side plates 23. Two symmetrical fans 251 are provided on the top plate 25 to dissipate heat from the plastic parts by using the fans 251.

[0032] It is worth noting that bearings 272 are fixedly installed on both side plates 23, and the end of the long shaft 271 is fixedly installed on the inner ring of the bearing 272 to reduce the friction of the feeding cylinder 273 and make the feeding cylinder 273 rotate more smoothly on the long shaft 271.

[0033] When using the demolding auxiliary device for plastic injection molded products of this utility model, the first drive motor 242 and the second drive motor 262 are started. After demolding, the plastic part falls down into the unloading hopper 20 and onto the first conveyor belt 241. As the first rotating shaft 24 rotates, it drives the first conveyor belt 241 to rotate, thus conveying the plastic part outward. When the plastic part falls from the end of the first conveyor belt 241 onto the second conveyor belt 261, the second conveyor belt 261 continues to convey the plastic part to the corresponding position as it rotates. In addition, the fan 251 is connected to an external power source and made to work. The fan 251 can perform heat dissipation operation on the plastic part conveyed on the first conveyor belt 241.
