[0026] Example 1
[0027] An injection molding machine for producing and processing plastic automobile parts, such as Figure 1-Figure 5As shown, it includes an injection molding machine body 1; a feed barrel 2 is fixedly connected to the injection molding machine body 1, and a screening mechanism 3 is arranged inside the feed barrel 2. The screening mechanism 3 includes a sieve plate 301, the sieve plate 301 is movably connected to the middle of the feed barrel 2, a scraper 302 is connected to the top of the sieve plate 301, and the scraper 302 is movably connected to the feed barrel 2. Cleaning grooves 303 corresponding to the position of the sieve plate 301 are provided on both sides of the inner wall of the feed barrel 2. The screening mechanism 3 can screen the injection molding raw material particles inside the feed barrel 2, so as to prevent impurities from entering the inside of the injection molding machine body 1 and causing the injection molding machine body 1 to be blocked and affect the injection molding effect. The sieve plate 301 has a mesh structure, and the sieve plate 301 can screen the injection molding raw material, so as to prevent impurities with larger particles from passing through the sieve plate 301. At the same time, the scraper 302 structure can cooperate with the sieve plate 301 to clean the filtered impurities and avoid the sieve plate 301 from being blocked and affecting the screening effect of the raw materials. The cleaning groove 303 structure can cooperate with the scraper 302 to collect the impurities cleaned by the scraper 302. The two sides of the top of the scraper 302 are slidably connected with driving rods 304, and the driving rods 304 are arranged through the top of the scraper 302. The bottom of the driving rod 304 is fixedly connected with a buffer spring 305, and the inner wall of the feed barrel 2 is fixedly connected with an oscillation block 306. The driving rod 304 structure can drive the scraper 302, so that the scraper 302 can move under the drive of the driving rod 304. At the same time, the slidingly connected driving rod 304 can be slidably adjusted inside the scraper 302 to buffer the impurities. The impact spring 305 structure can limit the position between the driving rod 304 and the scraper 302, so that the scraper 302 and the driving rod 304 keep away from each other. The oscillation block 306 is a serrated structure. The oscillation block 306 structure can drive the scraper 302, so that the scraper 302 can periodically approach and move away from the driving rod 304 during the movement, thereby utilizing the elasticity of the buffer spring 305 to continuously knock and oscillate the sieve plate 301, thereby improving the screening and filtering effect of the sieve plate 301 on the raw materials. A reciprocating screw rod 307 is rotatably connected to the feed barrel 2, and the reciprocating screw rod 307 is arranged through the driving rod 304. The reciprocating screw rod 307 and the driving rod 304 are meshed with each other. A guide rod 308 is fixedly connected to the inside of the feed barrel 2, and the guide rod 3 08 is set through the scraper 302, and the scraper 302 is provided with a guide groove 309 corresponding to the guide rod 308 structure. The reciprocating screw rod 307 can drive the driving rod 304, so that the driving rod 304 can continuously reciprocate along the reciprocating screw rod 307. At the same time, the driving rod 304 can drive the scraper 302 to move synchronously during the movement, thereby realizing the scraping and cleaning operation on the surface of the screen plate 301. The guide rod 308 structure can guide the movement of the scraper 302, thereby avoiding the scraper 302 from tilting and dislocating during the movement. The guide groove 309 structure can facilitate the sliding adjustment of the guide rod 308 to realize the movement of the scraper 302 along the direction of the driving rod 304. The injection molding machine body 1 is connected with a feeding screw 4.The feeding screw 4 and the end of the reciprocating screw 307 are fixedly connected with a sprocket 310, and the outer side of the sprocket 310 is meshed with a chain 311, and the chain 311 can drive the sprocket 310, so that the reciprocating screw can be driven by the continuously rotating feeding screw 4, so that the injection molding machine body 1 can synchronously drive the scraper 302 when it is running.
[0028] Example 2
[0029] like Figure 2-Figure 4 As shown, a cleaning mechanism 5 is provided on the feed barrel 2, and the cleaning mechanism 5 includes a cleaning plate 501, which is slidably connected to the inside of the cleaning groove 303, and a sealing plate 502 is fixedly connected to one end of the cleaning plate 501. The cleaning mechanism 5 can clean the impurities in the cleaning groove 303, so as to avoid excessive accumulation of impurities in the cleaning groove 303. The slidably connected cleaning plate 501 can move the impurities. At the same time, the cleaning plate 501 is a mesh structure, and the aperture of the cleaning plate 501 corresponds to the aperture of the sieve plate 301, so that the raw materials scraped into the cleaning groove 303 by the scraper 302 can be screened to separate the raw materials from the impurities. At the same time, the sealing plate 502 structure can close the cleaning groove 303, so that the cleaning plate 501 can avoid the scraper 302 from pushing the raw materials or impurities into the cleaning groove 303 when cleaning the impurities. A reciprocating screw rod 2 503 is rotatably connected to the inside of the cleaning groove 303, and the reciprocating screw rod 2 503 is arranged through the cleaning plate 501. The second 503 is meshed with the cleaning plate 501, and the ends of the reciprocating screw 1 307 and the reciprocating screw 2 503 are fixedly connected with a mutually meshing linkage gear 504. The reciprocating screw 2 503 can drive the cleaning plate 501 so that the cleaning plate 501 can be continuously reciprocated and raised, thereby improving the cleaning effect of the cleaning plate 501 on impurities. The linkage gear 504 is a bevel gear, and the linkage gears 504 mesh with each other and link the reciprocating screw 1 307 and the reciprocating screw 2 503. , so that the reciprocating screw rod 1 307 can drive the reciprocating screw rod 2 503 to rotate synchronously during the continuous rotation, and the inner wall and outer wall of the feeding barrel 2 are respectively provided with a screening port 505 and a slag discharge port 506, and the screening port 505 and the slag discharge port 506 are respectively connected with the cleaning trough 303. The screening port 505 can facilitate the raw material particles screened by the cleaning plate 501 to move from the inside of the cleaning trough 303 to the feeding barrel 2, and the slag discharge port 506 can facilitate the cleaning plate 501 to clean out impurities.
[0030] When the injection molding machine for producing and processing plastic automobile parts of the utility model is used, the raw materials of plastic automobile parts to be produced are poured into the inside of the feeding barrel 2, and the injection molding machine body 1 is started at the same time. When the feeding screw 4 is running and rotating, the chain 311 is driven by the sprocket 310 to continuously rotate and drive the reciprocating screw rod 307 to continuously rotate. The reciprocating screw rod 307 then drives the scraper 302 to continuously reciprocate along the reciprocating screw rod 307 through the driving rod 304, and the bottom end of the scraper 302 moves along the oscillation block 306. The serrated oscillation block 306 periodically drives the scraper 302 to move in the direction of the driving rod 304. At the same time, the buffer spring 305 at the end of the driving rod 304 periodically pushes the scraper 302 through elasticity to make the scraper 302 away from the driving rod 304. In the process of moving away from the driving rod 304, the scraper 302 contacts the screen plate 301 and knocks and oscillates the screen plate 301. At the same time, the scraper 302 pushes impurities to the feeding barrel 2. The two sides of the cylinder 2 push the impurities to approach the cleaning groove 303. The reciprocating screw rod 1 307 transmits the reciprocating screw rod 2 503 through the meshing linkage gear 504 during the continuous rotation. The reciprocating screw rod 2 503 then drives the cleaning plate 501 to move back and forth periodically along the reciprocating screw rod 2 503. When the scraper 302 moves toward the cleaning groove 303, the cleaning plate 501 inside the cleaning groove 303 continues to move downward and moves to the sieve plate 302 when the scraper 302 moves to the sieve plate 303. 1, the cleaning plate 501 moves to be flush with the height of the sieve plate 301, so that the scraper 302 can push the impurities onto the cleaning plate 501, and the cleaning plate 501 screens the fallen raw materials and impurities. The impurities stay on the cleaning plate 501, and the raw materials pass through the cleaning plate 501 and move from the sieve opening 505 to the inside of the feeding barrel 2. When the cleaning plate 501 rises to the slag discharge opening 506, the impurities on the cleaning plate 501 slide from the cleaning plate 501 to the outside of the feeding barrel 2.
