Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-4 This utility model provides a technical solution: a raw material pressurization device for injection molding of large multi-ribbed thin-walled plastic pallets, comprising:

[0031] The barrel 100 has a discharge pipe 200 at its bottom end that is connected to the injection molding pipe, and the surface of the discharge pipe 200 is provided with a discharge valve.

[0032] See Figure 1 The inner top wall of the material cylinder 100 is fixedly provided with a feeding pipe 500 extending to the upper surface of the material cylinder 100, and the top end of the feeding pipe 500 is provided with a sealing cap.

[0033] Specifically, by setting up the feeding pipe 500, it is easy to add raw materials into the material cylinder 100.

[0034] The material conveying assembly 300 includes a rotating rod 301 rotatably disposed on the top wall inside the material cylinder 100, and a drive motor 302 fixed on the upper surface of the material cylinder 100 for driving the rotating rod 301 to rotate. The surface of the rotating rod 301 is provided with a stirring blade 303, and the bottom end of the rotating rod 301 is fixed with a connecting rod 304 extending into the discharge pipe 200. The surface of the connecting rod 304 is fixed with a spiral conveying blade 305.

[0035] See Figure 3The output end of the drive motor 302 is fixedly provided with an active gear disk 306, and the top end of the rotating rod 301 is fixedly provided with a driven gear disk 307 that meshes with the active gear disk 306.

[0036] Specifically, by setting up an active gear disk 306 and a driven gear disk 307, it is convenient to drive the rotating rod 301 to rotate through the rotation of the drive motor 302.

[0037] In this embodiment, by setting up a material conveying assembly 300, the device can start the drive motor 302 when feeding material into the injection tube through the material cylinder 100. The rotation of the drive motor 302 drives the active gear disk 306 to rotate, which in turn drives the driven gear disk 307 and the rotating rod 301 to rotate. The rotation of the rotating rod 301 drives the stirring blade 303 to stir the raw material inside the material cylinder 100. At the same time, the rotation of the rotating rod 301 drives the connecting rod 304 to rotate, which in turn drives the spiral conveying blade 305 to rotate, so as to uniformly convey the raw material in the material cylinder 100 to the discharge pipe 200, thereby achieving the purpose of automatic uniform material conveying and avoiding material blockage.

[0038] Example 2

[0039] Based on Example 1, and differing from Example 1 in that,

[0040] A raw material pressurization device for injection molding of large multi-ribbed thin-walled plastic pallets further includes:

[0041] The pressurizing assembly 400 is used to pressurize the inside of the material cylinder 100. The pressurizing assembly 400 includes a pressurizing box 401 fixed on the upper surface of the material cylinder 100, and two press-type air pumps 402 fixed on the inner walls of both sides of the pressurizing box 401.

[0042] See Figure 3 , Figure 4 The pressurizing assembly 400 also includes a reciprocating screw 403 rotatably disposed on the inner wall of the pressurizing chamber 401, and a sliding plate 404 slidably disposed on the inner wall of the pressurizing chamber 401, and the surface of the sliding plate 404 is provided with a threaded hole that is threadedly connected to the outer surface of the reciprocating screw 403.

[0043] Specifically, by setting a reciprocating screw 403, the rotation of the reciprocating screw 403 can drive the slide plate 404 to move back and forth.

[0044] See Figure 4 One end of the reciprocating screw 403 extends to the outer surface of the pressure box 401 and is fixedly provided with a driven bevel gear 405. The surface of the rotating rod 301 is fixedly provided with a driving bevel gear 406 that meshes with the driven bevel gear 405.

[0045] Specifically, by setting the driving bevel gear 406 and the driven bevel gear 405, the rotation of the rotating rod 301 can drive the reciprocating screw 403 to rotate.

[0046] See Figure 4 The pressing ends of the two press-type air pumps 402 are fixedly connected to the two side surfaces of the slide plate 404, and the ends of the press-type air pumps 402 are provided with air inlet pipes 407 extending to the outer surface of the pressurization box 401. The surface of the air inlet pipes 407 is provided with one-way air inlet valves 408.

[0047] See Figure 1 , Figure 3 The surface of the press-type air pump 402 is provided with a pressurizing pipe 409 extending into the inside of the material cylinder 100, and the surface of the pressurizing pipe 409 is provided with an air outlet one-way valve 4010.

[0048] In this embodiment, by setting up a pressurizing component 400, the rotation of the rotating rod 301 drives the reciprocating screw 403 to rotate under the action of the active bevel gear 406 and the driven bevel gear 405. The rotation of the reciprocating screw 403 drives the slide plate 404 to move back and forth, thereby realizing the continuous reciprocating pressing of the two press-type air pumps 402, and thus realizing the purpose of continuously pressurizing the inside of the barrel 100, thereby realizing the purpose of pressurizing the inside of the injection tube, so that the molten raw material in the injection tube can be quickly discharged into the mold.

[0049] Working principle: When the device feeds material into the injection molding tube through the material cylinder 100, it can start the drive motor 302. The rotation of the drive motor 302 drives the active gear disc 306 to rotate. The rotation of the active gear disc 306 drives the driven gear disc 307 and the rotating rod 301 to rotate. The rotation of the rotating rod 301 drives the stirring blade 303 to stir the material inside the material cylinder 100. At the same time, the rotation of the rotating rod 301 drives the connecting rod 304 to rotate. The rotation of the connecting rod 304 drives the screw conveyor blade 305 to rotate, so as to uniformly convey the material in the material cylinder 100 to the discharge point. Within the tube 200, automatic and uniform material feeding is achieved, preventing material blockage. Furthermore, the rotation of the rotating rod 301, under the action of the driving bevel gear 406 and the driven bevel gear 405, drives the reciprocating screw 403 to rotate. The rotation of the reciprocating screw 403 drives the slide plate 404 to move back and forth, thereby achieving continuous reciprocating pressing of the two press-type air pumps 402, and thus achieving continuous pressurization of the inside of the material cylinder 100. This pressurizes the inside of the injection tube, facilitating the rapid discharge of the molten material into the mold.

[0050] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
