[0033] The cleaning cavity is provided with a first screen 21 and a second screen 22; the first screen 21 and the second screen 22 divide the cleaning cavity into an inner cavity 13 and an outer cavity 14; the shredding cavity 12 is arranged at the top of the inner cavity 13; the bottom of the inner cavity 13 and the bottom of the outer cavity 14 are communicated;

[0034] The inner cavity 13 is liftably provided with a lifting rod 4; the two ends of the lifting rod 4 are respectively rotationally provided with a first baffle assembly and a second baffle assembly.

[0035] Specifically, the water gap waste recycling device of the injection molded part provided in the embodiment drives the tearing roller assembly to rotate, the inner cavity 13 and the outer cavity 14 of the cleaning cavity are both provided with cleaning liquid, the water gap waste falls from the hopper 11 into the tearing cavity 12, and after being torn by the tearing roller assembly, it falls into the inner cavity 13. Because the density of the water gap waste is low, the torn water gap waste floats on the liquid surface of the inner cavity 13, then the lifting rod 4 drives the first baffle assembly and the second baffle assembly to move upward to the liquid surface of the inner cavity 13, then the first baffle assembly and the second baffle assembly are flipped, and the first baffle assembly and the second baffle assembly abut, so that the torn water gap waste abuts on the bottom surface of the first baffle assembly and the bottom surface of the second baffle assembly, then the lifting rod 4 drives the first baffle assembly and the second baffle assembly to move downward, until the first baffle assembly and the second baffle assembly drive the water gap waste to the bottom of the inner cavity 13, and then the water gap waste moves from the inner cavity 13 to the outer cavity 14, so that the water gap waste can be fully contacted with the cleaning liquid, and the problem of incomplete cleaning caused by the floating of low-density plastic scraps is effectively solved.

[0036] The water gap waste recycling device of the injection molded part provided in the embodiment, the tearing roller assembly includes a first tearing roller 31 and a second tearing roller 32 arranged opposite to each other; the driving assembly includes a first gear 33, a second gear 34 and a driving gear 35 all rotatably arranged in the box body 1; the driving assembly further includes a motor 36 arranged in the box body 1; the output end of the motor 36 is connected with the driving gear 35; the first gear 33 is arranged between the second gear 34 and the driving gear 35; the two ends of the first gear 33 are respectively engaged with the second gear 34 and the driving gear 35; the first gear 33 is connected with the first tearing roller 31; and the second tearing roller 32 is connected with the second tearing roller 32.

[0037] Specifically, the motor 36 is started to drive the driving gear 35 to rotate, so that the first gear 33 and the second gear 34 rotate in opposite directions to drive the second tearing roller 32 and the second tearing roller 32 to rotate in opposite directions, so that the water gap waste is torn after passing between the second tearing roller 32 and the second tearing roller 32.

[0038] The water gap waste recycling device of the injection molded part provided in the embodiment, the first baffle assembly and the second baffle assembly both include an inner baffle 51 and an outer baffle 52; the inner baffle 51 is telescopically movably arranged at one side of the outer baffle 52; a telescopic spring 53 is arranged between the inner baffle 51 and the outer baffle 52; and an inclined surface is arranged on the bottom surface of the outer baffle 52. By arranging the inclined surface on the bottom surface of the outer baffle 52, it is convenient for the first baffle assembly and the second baffle assembly to drive the water gap waste to the bottom of the inner cavity 13, and it is beneficial for the water gap waste to move from the inner cavity 13 to the outer cavity 14.

[0039] The sprue waste recycling device for injection molded parts described in this embodiment has a flipping boss 54 at one end of the inner baffle 51; flipping strip grooves 41 at both ends of the lifting rod 4; the flipping boss 54 is movably disposed in the flipping strip grooves 41; the flipping boss 54 has a flipping tooth groove 55; the flipping strip groove 41 has a flipping rack 42 that cooperates with the flipping tooth groove 55; and a flipping tension spring 43 is provided between the flipping boss 54 and the lifting rod 4.

[0040] Specifically, with the above configuration, when the flipping boss 54 moves in the flipping strip groove 41, the flipping boss 54 will rotate due to the meshing action of the flipping tooth groove 55 and the flipping rack 42, thereby causing the inner baffle 51 and the outer baffle 52 to flip.

[0041] This embodiment describes a device for recycling sprue waste from injection molded parts. The inner wall of the inner cavity 13 is provided with a lifting guide groove; the other end of the inner baffle 51 is provided with a lifting boss 56; the lifting boss 56 is movably disposed within the lifting guide groove; the lifting guide groove includes an inner guide vertical groove 61, an outer guide vertical groove 62, an upper guide horizontal groove 63, and a lower guide horizontal groove 64; the upper guide horizontal groove 63 is connected to the top of the inner guide vertical groove 61 and the top of the outer guide vertical groove 62 respectively; the lower guide horizontal groove 64 is connected to the bottom of the inner guide vertical groove 61 and the bottom of the outer guide vertical groove 62 respectively; the inner guide vertical groove 61 and the outer guide vertical groove 62 are respectively used for sliding connection with the lifting boss 56; both the first mesh plate 21 and the second mesh plate 22 are provided with elastic blocks 23 at corresponding positions in the lower guide horizontal groove 64.

[0043] When the lifting rod 4 moves upward, the lifting boss 56 moves upward along the inner guide vertical groove 61, and the flipping spring 43 remains stretched until the lifting boss 56 moves to the upper guide horizontal groove 63. At this point, the flipping spring 43 resets, causing the lifting boss 56 to move to one end of the upper guide horizontal groove 63 near the outer guide vertical groove 62. During the movement of the lifting boss 56 and the inner baffle 51, the flipping boss 54 simultaneously moves in the flipping strip groove 41. Due to the meshing action of the flipping tooth groove 55 and the flipping rack 42, the flipping boss 54 rotates, causing the inner baffle 51 and the outer baffle 52 to flip. The two outer baffles 52 then abut against each other, forming... Figure 4In the shown state, the inner baffle 51 and the outer baffle 52 are in a horizontal arrangement, and the shredded nozzle waste is supported against the bottom surface of the first baffle assembly and the bottom surface of the second baffle assembly.

[0044] Then the lifting rod 4 moves downward, so that the lifting boss 56 moves upward along the outer guide vertical groove 62, the two outer baffles 52 remain in the abutting state, until the lifting boss 56 moves to the lower guide horizontal groove 64, the nozzle waste moves from the inner cavity 13 to the outer cavity 14, and under the action of the elastic stopper 23, the lifting boss 56 moves to one end of the lower guide horizontal groove 64 close to the inner guide vertical groove 61, the turnover spring 43 is in a stretched state again, and in the process of moving of the lifting boss 56 and the inner baffle 51, the turnover boss 54 moves in the turnover strip-shaped groove 41 at the same time, due to the meshing action of the turnover tooth groove 55 and the turnover rack 42, the turnover boss 54 is driven to rotate, so that the inner baffle 51 and the outer baffle 52 are turned over, so as to be turned over to the vertical arrangement again.
