[0001] The utility model relates to the technical field of extrusion mechanisms, in particular to an energy-saving extrusion mechanism for an injection molding machine. Background Art

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. They are available in vertical, horizontal, and all-electric models. They heat the plastic and apply high pressure to the molten plastic, causing it to be ejected and fill the mold cavity.

[0003] For example, Chinese patent publication No. CN210501262U discloses an efficient and energy-saving extrusion mechanism for an injection molding machine, which mainly records that it not only avoids the waste of materials when the extrusion mechanism is used, avoids the solidification of materials when the extrusion mechanism is used, but also avoids the confusion of different materials when the extrusion mechanism is used.

[0004] When the extrusion mechanism is in use, it effectively prevents the solidification of the material during use through structures such as the telescopic rod, the shaking rod, the hopper, and the hollow adjusting ball. However, in actual use, the hopper cannot achieve the ideal vibration effect only through the cooperation between the telescopic rod and the hollow adjusting ball, which makes it easy for the material to be blocked in the injection molding machine, making the injection molding machine unusable, thereby reducing the working efficiency of the extrusion mechanism.

[0005] For this reason, we need to provide an energy-saving extrusion mechanism for injection molding machines. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0029] Example 1:

[0030] An energy-saving extrusion mechanism for an injection molding machine includes a mechanism housing 1 and a support base 2, wherein a processing structure is provided above the mechanism housing 1;

[0031] The processing structure includes a vibration mechanism 3 and an extrusion mechanism 4;

[0032] The vibration mechanism 3 includes a discharge pipe 301, a buffer box 302, a motor 303, a rotating rod 304, and a stirring roller 305. The top of the discharge pipe 301 is connected to the bottom of the buffer box 302. One side of the buffer box 302 is connected to one end of the motor 303. The output end of the motor 303 is connected to one end of the rotating rod 304. The outer wall of the rotating rod 304 is connected to the inner wall of the stirring roller 305. The outer wall of the rotating rod 304 is fixedly installed with a bevel gear 306. The outer wall of the bevel gear 306 is meshed with an umbrella. Gear 2 307, a rotating rod 2 308 is fixedly installed on the top of the bevel gear 2 307, and a fixed plate 1 309 is rotatably connected to the top of the rotating rod 2 308. A cam 310 is fixedly installed on the outer wall of the rotating rod 2 308, and one end of the cam 310 is pressed and contacted with a force plate 311. A movable plate 312 is fixedly installed on one end of the force plate 311. A guide rod 313 is slidably connected to the inner wall of the movable plate 312, and one end of the guide rod 313 is fixedly installed with a fixed plate 2 314. A hopper 315 is fixedly installed on the top of the movable plate 312;

[0033] In this embodiment, there are two stirring rollers 305, which are symmetrically distributed on the outer wall of the rotating rod 304, and two movable plates 312, which are symmetrically distributed at both ends of the force-bearing plate 311, so that the raw materials entering the buffer box 301 can be stirred and the hopper 315 can be moved back and forth.

[0034] Furthermore, there are two guide rods 313, which are symmetrically distributed on the inner walls of the two movable plates 312. There are two second fixed plates 314, which are symmetrically distributed on one end of the two guide rods 313. A spring is fixedly installed between one side of the movable plate 312 and one side of the second fixed plate 314, thereby effectively increasing the stability of the hopper 315 during movement, thereby better pouring the raw materials.

[0035] Furthermore, the bottom of the mechanism housing 1 is connected to the top of the support base 2, the top of the mechanism housing 1 is connected to the bottom of the discharge pipe 301, and one end of the mechanism housing 1 is connected to one end of the drive motor 401.

[0036] During use, when it is needed, the operator pours the raw materials into the hopper 315, and the raw materials flow into the buffer box 302 through the hopper 315, and flow into the mechanism housing 1 through the discharge pipe 301, and the motor 303 is started to drive the rotating rod 1 304 to rotate, and the rotating rod 1 304 is rotated to drive the stirring roller 305 to rotate, and the stirring roller 305 is rotated to stir the raw materials, thereby effectively preventing the raw materials from accumulating in the buffer box 302, and the rotating rod 1 304 is rotated to drive the bevel gear 1 306 to rotate, and the bevel gear 1 306 is rotated to drive the bevel gear 2 307 to rotate, and the bevel gear 2 307 is rotated to drive the bevel gear 2 The rotating rod 308 rotates, and the rotation of the rotating rod 308 drives the cam 310 to rotate. The rotation of the cam 310 can squeeze the force plate 311 to move, and the movement of the force plate 311 drives the movable plate 312 to slide on the guide rod 313. The sliding of the movable plate 312 stretches the spring and drives the hopper 315 to move. When the cam 310 is not in contact with the force plate 311, the elastic force of the spring can reset the hopper 315, and then the hopper 315 can be reciprocated and vibrated, thereby effectively preventing the raw material from solidifying in the hopper 315 and effectively preventing accumulation, so that the extrusion work can be better performed.

[0037] Example 2:

[0038] On the basis of Example 1, the extrusion mechanism 4 includes a drive motor 401, an extrusion screw 402, a connecting plate 403, a limit block 404, and a threaded rod 405. The output end of the drive motor 401 is connected to one end of the extrusion screw 402, the outer wall of the extrusion screw 402 is connected to one end of the connecting plate 403, the other end of the connecting plate 403 is in extrusion contact with the inner side of the limit block 404, the inner wall of the limit block 404 is threadedly connected to the outer wall of the threaded rod 405, a scraper 406 is fixedly installed at one end of the limit block 404, and one end of the mechanism housing 1 is connected to a discharge cover 407;

[0039] In this embodiment, there are four connecting plates 403, which are symmetrically distributed on the outer wall of the extrusion screw 402, and four limiting blocks 404, which are symmetrically distributed on one end of the four connecting plates 403, so that the scraper 406 can be quickly and conveniently disassembled and assembled, thereby better performing the scraping work;

[0040] Furthermore, the shape of the limit block 404 is U-shaped, and the number of scrapers 406 is two, and the scrapers 406 are symmetrically distributed at one end of the four limit blocks 404, so that the raw materials remaining on the inner wall of the mechanism shell 1 can be better scraped off, thereby better performing the extrusion work.

[0041] During use, when it is needed, the operator pours the raw material into the hopper 315, and the raw material flows into the buffer box 302 through the hopper 315, and flows into the mechanism housing 1 through the discharge pipe 301. By starting the vibration mechanism 3, the accumulation and solidification of the raw material can be effectively prevented, so that the extrusion work can be better performed. After the raw material enters the mechanism housing 1, the driving motor 401 is started to drive the extrusion screw 402 to rotate. The rotation of the extrusion screw 402 can extrude the raw material through the discharge cover 407, and as the extrusion screw 402 rotates, the connecting plate 403 is driven to rotate. The scraper 406 can be indirectly driven to rotate by rotating the connecting plate 403. As the scraper 406 rotates, the raw materials remaining on the inner wall of the mechanism housing 1 can be scraped off. When the scraper 406 needs to be disassembled, the movable door on the front of the installation mechanism housing 1 is opened and the threaded rod 405 is rotated to move in the limit block 404, so that the threaded rod 405 can be pulled out of the connecting plate 403, thereby canceling the limit fixation of the connecting plate 403 and removing the scraper 406 from the mechanism housing 1. When installation is required, the above steps can be repeated in reverse, which makes it more convenient for operators to use.
