[0026] 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.

[0027] See also Figure 1 - Figure 6 , the utility model provides a technical solution:

[0028] Example 1:

[0029] An injection molding device for decorative film of automotive interior parts includes an injection molding machine 1 and a lower hopper 2. The lower hopper 2 is fixedly connected to the top of the injection molding machine 1. A scraper 3 is provided inside the hopper. The top of the scraper 3 extends through the top of the lower hopper 2 and is fixedly connected to a transmission block 4. A transmission mechanism is provided on one side of the lower hopper 2, and a vibration mechanism is provided on the top of the transmission mechanism.

[0030] The transmission mechanism includes a motor 5 fixedly connected to the top of the injection molding machine 1, the output end of the motor 5 is fixedly connected to a rotating rod 6, the top of the rotating rod 6 is fixedly connected to a gear 7, the surface of the lower hopper 2 is provided with a gear ring 8, the top of the gear ring 8 is fixedly connected to a transmission rod 9, and the top of the transmission rod 9 is fixedly connected to the bottom of the transmission block 4.

[0031] In this embodiment, it is taken into consideration that during the material discharge process, particles are easily adsorbed on the inner wall of the discharge hopper 2, causing uneven material discharge, thereby affecting the effect of subsequent decorative film forming. Therefore, by providing a transmission mechanism, after the raw material particles are placed in the discharge hopper 2, the motor 5 is started to drive the rotating rod 6 and the gear 7 to rotate, and the gear 7 drives the gear ring 8 to rotate around the trajectory of the positioning block 21 and the positioning chute 22. The gear ring 8 drives the transmission rod 9, the transmission block 4 and the scraper 3 to rotate. When the scraper 3 rotates, it scrapes off the raw material particles adsorbed on the inner wall of the discharge hopper 2, avoiding the uneven material discharge and improving the effect of decorative film forming.

[0032] The problem that particles are easily adsorbed on the inner wall of the discharge hopper 2 during the discharge process, resulting in uneven discharge and affecting the subsequent decorative film forming effect is solved.

[0033] Preferably, two positioning blocks 21 are fixedly connected to the surface of the lower hopper 2 , and a positioning slot 22 used in conjunction with the positioning blocks 21 is provided on the inner wall of the gear ring 8 .

[0034] In this embodiment, by providing the positioning block 21 and the positioning slot 22, the gear 7 can be restricted from rotating around the positioning block 21 and the positioning slot 22 when transmitting to the gear ring 8, thereby limiting the rotation trajectory.

[0035] Preferably, both sides of the scraper 3 are sloped.

[0036] In this embodiment, by providing the scraper 3 , both sides of the scraper 3 can be set to be sloped, so that when the scraper 3 scrapes off the raw material particles, the surface raw material particles can adhere to the scraper 3 .

[0037] Example 2:

[0038] On the basis of Example 1, the transmission mechanism in this embodiment can control the scraper 3 to scrape off the raw material particles inside the lower hopper 2. However, considering that the raw material particles in the lower hopper 2 cannot fall quickly into the injection molding machine 1, they will still adhere to the inner wall of the lower hopper 2 again. The vibration mechanism in this application includes an extrusion block 10 fixedly arranged on the top of the gear 7, and the top of the gear 7 is fixedly connected to an extrusion rod 11 used in conjunction with the extrusion block 10. Two sliding rods 12 are provided at the bottom of the extrusion block 10, one end of the sliding rod 12 is fixedly connected to the inner wall of the lower hopper 2, and the other end of the sliding rod 12 is fixedly connected to the limiting block 13. The surface of the sliding rod 12 is slidably connected to the sliding block 14, the top of the sliding block 14 is fixedly connected to the top of the extrusion block 10, and the bottom of the sliding block 14 is fixedly connected to a moving block 15. One side of the moving block 15 is fixedly connected to a knocking rod 16, and one side of the sliding block 14 is fixedly connected to a spring 17, and one end of the spring 17 is fixedly connected to one side of the limiting block 13.

[0039] In this embodiment, it is considered that if the raw material particles in the lower hopper 2 cannot fall into the injection molding machine 1 quickly, they will still adhere to the inner wall of the lower hopper 2 again. Therefore, a vibration mechanism is provided to drive the extrusion rod 11 to rotate when the gear 7 rotates. Figure 6 As shown, during the rotation of the extrusion rod 11, its surface will squeeze the inner wall of the arc groove 19, driving the extrusion block 10 to move to the right. When the extrusion rod 11 does not move with the arc groove 19, it will be affected by the reaction force of the spring 17, pushing the sliding block 14 to move along the trajectory of the sliding rod 12 to reset, and at the same time drive the moving block 15 and the knocking rod 16 to reset, so that the knocking rod 16 knocks on the protective block 20 to generate vibration, thereby cyclically and intermittently knocking to generate vibration, thereby increasing the rate of raw material particles to be discharged, and preventing them from adhering to the inside of the lower hopper 2 again, and also preventing the raw material particles from adhering to the inner wall of the lower hopper 2;

[0040] Solve the problem that if the raw material particles in the lower hopper 2 cannot fall into the injection molding machine 1 quickly, they will still adhere to the inner wall of the lower hopper 2 again;

[0041] It should be noted that Figure 6 S1 is the moving track of the transmission rod 9, and S2 is the moving track of the extrusion block 10.

[0042] Preferably, a sliding hole 18 is formed on one side of the sliding block 14 , and the sliding hole 18 cooperates with the sliding rod 12 .

[0043] In this embodiment, by setting the sliding hole 18, a moving trajectory can be provided for the sliding block 14 to slide, and at the same time, the extrusion block 10 is restricted when the extrusion rod 11 is extruded, so that the extrusion block 10 and the sliding block 14 and other structures can only move along the trajectory of the sliding rod 12 and the sliding hole 18.

[0044] Preferably, an arcuate groove 19 is provided on one side of the extrusion block 10 , and the arcuate groove 19 cooperates with the extrusion rod 11 .

[0045] In this embodiment, by providing the arc groove 19 , when the transmission rod 9 rotates and contacts the arc groove 19 , the extrusion block 10 can be driven to move more easily.

[0046] Preferably, a protective block 20 is fixedly connected to one side of the lower hopper 2 , and the protective block 20 is opposite to the knocking rod 16 .

[0047] In this embodiment, the protection block 20 is provided to prevent the knocking rod 16 from directly knocking on the surface of the lower hopper 2, thereby preventing the lower hopper 2 from being damaged due to knocking.

[0048] Working principle: After placing the raw material particles in the lower hopper 2, the user starts the motor 5 to drive the rotating rod 6 and the gear 7 to rotate. The gear 7 drives the gear ring 8 to rotate around the trajectory of the positioning block 21 and the positioning chute 22. The gear ring 8 drives the transmission rod 9, the transmission block 4 and the scraper 3 to rotate. When the scraper 3 rotates, it scrapes off the raw material particles adsorbed on the inner wall of the lower hopper 2, avoiding uneven material discharge and improving the effect of decorative film forming.

[0049] When the gear 7 rotates, it drives the extrusion rod 11 to rotate. Figure 6 As shown, during the rotation of the extrusion rod 11, its surface will squeeze the inner wall of the arc groove 19, driving the extrusion block 10 to move to the right. When the extrusion rod 11 does not move with the arc groove 19, it will be affected by the reaction force of the spring 17, and will push the sliding block 14 to move along the trajectory of the sliding rod 12 to reset, and at the same time drive the moving block 15 and the knocking rod 16 to reset, so that the knocking rod 16 knocks on the protective block 20 to generate vibration, and thus the intermittent knocking in a cycle generates vibration, thereby increasing the rate of raw material particle discharge and preventing them from adhering to the inside of the lower hopper 2 again. At the same time, it can also prevent the raw material particles from adhering to the inner wall of the lower hopper 2.

[0050] It should be noted that the motor 5 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 5 are clear to those skilled in the art, so they will not be described in detail.
