[0019] The embodiment of the present application discloses an injection molding positioning auxiliary mechanism for automotive parts. Refer to Figures 1-3 , an injection molding positioning auxiliary mechanism for automotive parts, including an injection molding device 1. A fixed mold 2 is arranged on one side of the injection molding device 1. Positioning guide rods 3 are fixedly installed near the four corners on one side of the fixed mold 2. A movable mold 4 is movably installed on the outer surface of the positioning guide rods 3. A processing groove 5 is formed in the middle of one side of the movable mold 4. Fixed frames 6 are symmetrically welded at both the front and rear ends of the movable mold 4. A limiting pressing plate 7 is rotatably installed on the outer surface of one side of the fixed frame 6. One side edge of the limiting pressing plate 7 is movably close to the processing groove 5. One end of the processing groove 5 is mutually attached to the surface of one side of the movable mold 4. An inner groove 8 is formed in the middle of one side of the fixed frame 6. One end of the hinge shaft of the limiting pressing plate 7 extends into the inner groove 8 and is installed with a gear 9. A movable frame 11 is movably installed on the outer surface of the positioning guide rod 3 near the movable mold 4. Circular holes are formed through the four corners on one side of the movable frame 11. The outer surface of the positioning guide rod 3 is located inside the circular holes, and the positioning guide rod 3 and the circular holes are mutually engaged. An adjusting component is further provided on the outer surface of the movable frame 11 for controlling the rotation of the limiting pressing plate 7.

[0020] The fixed mold 2 and the movable mold 4 are used to injection mold the automotive parts. The external drive controls the movable mold 4 to move along the outer surface of the positioning guide rod 3, separates the fixed mold 2 and the movable mold 4, and the movable mold 4 drives the fixed frame 6 to move close to the position of the rack plate 13. Then, the gear 9 rotates along the outer surface of the rack plate 13, and the rotating gear 9 drives the limiting pressing plate 7 to move synchronously. Then, the limiting pressing plate 7 rotates and presses on the outer surface of the automotive parts, and the limiting pressing plate 7 positions and supports the automotive parts, reflecting the positioning and supporting effect of multiple limiting pressing plates 7 on the automotive parts in the processing groove 5.

[0021] Refer to Figure 2 and Figure 3 , the adjusting component includes an electric telescopic rod 10. The electric telescopic rod 10 is fixedly arranged on the upper surface of the injection molding device 1. The output end on one side of the electric telescopic rod 10 is connected to the middle of one side of the movable frame 11. Connecting pieces 12 are symmetrically welded at both the front and rear ends of the movable frame 11. A rack plate 13 is fixedly installed at one end of the connecting piece 12. One end edge of the rack plate 13 is movably close to the outer surface of the gear 9, and the gear 9 and the rack plate 13 are mutually engaged.

[0022] [[ID=,15]]By starting the electric telescopic rod 10 to push the movable frame 11 to move along the outer surface of the positioning guide rod 3, the movable frame 11 moves and pushes the rack plate 13 to move along the outer surface of the gear 9, the rack plate 13 drives the gear 9 to rotate in the reverse direction, and the limiting pressing plate 7 rotates with the gear 9 to cancel the limit on the opening of the processing groove 5, and then the automotive parts are taken out from the processing groove 5, reflecting the activity adjustment effect of the limiting pressing plate 7.

[0023] The implementation principle of an injection molding positioning assistance mechanism for automotive parts in an embodiment of this application is as follows: The automotive parts are injection molded by the fixed mold 2 cooperating with the moving mold 4. The external drive controls the moving mold 4 to interact along the outer surface of the positioning guide rod 3, separating the fixed mold 2 and the moving mold 4 from each other. The moving mold 4 drives the fixed frame 6 to approach the rack plate 13, and then the gear 9 rotates along the outer surface of the rack plate 13. The rotating gear 9 drives the limit pressing plate 7 to move synchronously. Then the limit pressing plate 7 rotates and presses on the outer surface of the automotive part, and the limit pressing plate 7 positions and supports the automotive part. When the moving mold 4 moves to the material taking position, the electric telescopic rod 10 is started to push the movable frame 11 to move along the outer surface of the positioning guide rod 3. Then the movable frame 11 moves to push the rack plate 13 to move along the outer surface of the gear 9, and the rack plate 13 drives the gear 9 to rotate in the reverse direction, so that the limit pressing plate 7 rotates with the gear 9 to cancel the limit on the opening of the processing groove 5, and then the automotive part is taken out from the processing groove 5. The input end of the power supply of the electric telescopic rod 10 is electrically connected to the output end of the external power supply. Compared with the prior art, this solution has the effect of facilitating the limit and resistance of the processed and formed automotive parts, improving the positioning effect of the automotive parts when the moving mold 4 moves, and solving the problem that the automotive parts fall from the processing groove 5 when the moving mold 4 moves.
