Specific embodiments

[0031] The present invention will be further described in conjunction with the following embodiments.

[0032] As Figures 1 to 9 it can be seen, a runner waste recycling device for injection molded parts described in this embodiment includes a box body 1; the box body 1 is provided with a hopper 11, a shredding chamber 12 and a cleaning chamber; the hopper 11 is arranged at the top of the shredding chamber 12; the cleaning chamber is arranged at the bottom of the shredding chamber 12; the shredding chamber 12 is rotatably provided with a shredding roller assembly; the box body 1 is provided with a driving assembly for driving the shredding roller assembly to rotate;

[0033] The cleaning chamber is provided with a first mesh plate 21 and a second mesh plate 22; the first mesh plate 21 and the second mesh plate 22 divide the cleaning chamber into an inner cavity body 13 and an outer cavity body 14; the shredding chamber 12 is arranged at the top of the inner cavity body 13; the bottom of the inner cavity body 13 communicates with the bottom of the outer cavity body 14;

[0034] The inner cavity body 13 is provided with a lifting rod 4 that moves up and down; both ends of the lifting rod 4 are rotatably provided with a first baffle assembly and a second baffle assembly respectively.

[0035] Specifically, for the runner waste recycling device of the injection molded part in this embodiment, the driving assembly drives the shredding roller assembly to rotate. Cleaning liquid is provided in both the inner cavity 13 and the outer cavity 14 of the cleaning chamber. The runner waste falls from the hopper 11 into the shredding chamber 12, and after being shredded by the shredding roller assembly, it drops into the inner cavity 13. Since the density of the runner waste is relatively low, the shredded runner 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. Next, the first baffle assembly and the second baffle assembly flip, and the first baffle assembly abuts against the second baffle assembly, causing the shredded runner waste to abut against the bottom surfaces of the first baffle assembly and 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 runner waste to the bottom of the inner cavity 13. After that, the runner waste moves from the inner cavity 13 to the outer cavity 14, so that the runner waste can fully contact the cleaning liquid, effectively solving the problem of incomplete cleaning caused by the floating of low-density plastic scraps.

[0036] For a runner waste recycling device of an injection molded part in this embodiment, the shredding roller assembly includes a first shredding roller 31 and a second shredding roller 32 which are oppositely arranged; the driving assembly includes a first gear 33, a second gear 34 and a driving gear 35 which are 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 to the driving gear 35; the first gear 33 is arranged between the second gear 34 and the driving gear 35; both ends of the first gear 33 are meshed with the second gear 34 and the driving gear 35 respectively; the first gear 33 is connected to the first shredding roller 31; the second shredding roller 32 is connected to the second shredding roller 32.

[0037] Specifically, in this embodiment, by starting the motor 36, the motor 36 drives the driving gear 35 to rotate, so that the first gear 33 and the second gear 34 rotate in opposite directions, driving the second shredding roller 32 and the second shredding roller 32 to rotate in opposite directions, so that the runner waste is shredded after passing between the second shredding roller 32 and the second shredding roller 32.

[0038] For a runner waste recycling device of an injection molded part in this embodiment, both the first baffle assembly and the second baffle assembly include an inner baffle 51 and an outer baffle 52; the inner baffle 51 is telescopically and movably arranged on one side of the outer baffle 52; a telescopic spring 53 is arranged between the inner baffle 51 and the outer baffle 52; the bottom surface of the outer baffle 52 is provided with an inclined surface. In this embodiment, by providing an 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 runner waste to the bottom of the inner cavity 13, which is beneficial for the runner waste to move from the inner cavity 13 to the outer cavity 14.

[0039] A sprue waste recycling device for an injection molded part according to this embodiment. One end of the inner baffle 51 is provided with a flipping boss 54; both ends of the lifting rod 4 are provided with flipping strip grooves 41; the flipping boss 54 is movably arranged in the flipping strip groove 41; the flipping boss 54 is provided with a flipping tooth groove 55; the flipping strip groove 41 is provided with a flipping rack 42 that cooperates with the flipping tooth groove 55; a flipping tension spring 43 is arranged between the flipping boss 54 and the lifting rod 4.

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

[0041] A sprue waste recycling device for an injection molded part according to this embodiment. 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 arranged in 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 respectively connected to the top of the inner guide vertical groove 61 and the top of the outer guide vertical groove 62; the lower guide horizontal groove 64 is respectively connected to the bottom of the inner guide vertical groove 61 and the bottom of the outer guide vertical groove 62; the inner guide vertical groove 61 and the outer guide vertical groove 62 are respectively used for sliding connection with the lifting boss 56; the first mesh plate 21 and the second mesh plate 22 are both provided with elastic stoppers 23 at corresponding positions of the lower guide horizontal groove 64.

[0042] Specifically, for the sprue waste recycling device for an injection molded part according to this embodiment, before extruding the sprue waste, as Figure 6 shown, at this time the lifting rod 4 is located at the bottom of the inner cavity 13. Under the action of the elastic stopper 23, the lifting boss 56 is located at one end of the lower guide horizontal groove 64 close to the inner guide vertical groove 61, and the flipping tension spring 43 is in a stretched state. At this time, the inner baffle 51 and the outer baffle 52 are in a vertically arranged state.

[0043] When the lifting rod 4 moves upward, the lifting boss 56 moves upward along the inner guide vertical groove 61, and the flipping tension spring 43 remains in a stretched state until the lifting boss 56 moves to the upper guide horizontal groove 63. At this time, the flipping tension spring 43 resets, so that the lifting boss 56 moves to one end of the upper guide horizontal groove 63 close to the outer guide vertical groove 62. And during the movement of the lifting boss 56 and the inner baffle 51, the flipping boss 54 moves in the flipping strip groove 41 at the same time. Due to the meshing effect of the flipping tooth groove 55 and the flipping rack 42, it will drive the flipping boss 54 to rotate, thereby causing the inner baffle 51 and the outer baffle 52 to flip, and the two outer baffles 52 abut against each other to form Figure 4In the shown state, at this time, the inner baffle 51 and the outer baffle 52 are in a horizontally arranged state, and the shredded nozzle waste is abutted 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 guiding vertical groove 62, and the two outer baffles 52 remain in an abutting state. Until the lifting boss 56 moves to the lower guiding 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 is pushed to move to one end of the lower guiding horizontal groove 64 close to the inner guiding vertical groove 61, and the flipping spring 43 is in a stretched state again. And during the movement of the lifting boss 56 and the inner baffle 51, the flipping boss 54 moves in the flipping strip groove 41 at the same time. Due to the meshing action between the flipping tooth groove 55 and the flipping rack 42, the flipping boss 54 will be driven to rotate, so that the inner baffle 51 and the outer baffle 52 are flipped, so that they are flipped back to the vertically arranged state.

[0045] In a nozzle waste recycling device for an injection molded part according to this embodiment, a linkage assembly is provided between the motor 36 and the lifting rod 4; the motor 36 drives the lifting rod 4 to move up and down through the linkage assembly.
