[0002] Injection molds are tools for producing plastic products; they also give plastic products a complete structure and precise dimensions. However, existing household appliance injection molds require mixing injection materials during production, which can cause adhesion inside the mixing equipment, thus affecting the efficiency of mold production. Summary of the Invention

[0003] To address this issue, this utility model provides an automatic mixing device for household appliance injection molds. The user places the material into a mixing tank, closes the two covers, and engages the two second gears with the first gear. This activates the drive motor, causing the mixing mechanism to mix the material.

Detailed Implementation

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 - Appendix Figure 4 The present invention provides an automatic mixing device for injection molds of household appliances, including a mixing tank 1, which is circular in structure, with a discharge pipe 2 at the bottom of the mixing tank 1 and a positioning frame 3 fixedly connected to the top of the mixing tank 1.

[0028] The mixing tank 1 is equipped with a mixing mechanism, which is used to mix the mold materials.

[0029] An anti-adhesion mechanism is located at the top of the mixing tank 1. The anti-adhesion mechanism is used to push the material on the inner wall of the mixing tank 1 downward.

[0030] The mixing mechanism includes a drive motor 4, which is located on the top of the positioning frame 3. The output end of the drive motor 4 is fixedly connected to a drive shaft 5, and the bottom end of the drive shaft 5 extends into the interior of the mixing tank 1.

[0031] In this embodiment, the user puts the material into the mixing barrel 1 and covers the two cover plates 12, so that the two second gears 20 mesh with the first gear 19, and starts the transmission motor 4 to work, so that the mixing mechanism mixes the material. At the same time, the anti-sticking mechanism pushes the material off the inner wall of the mixing barrel 1 to prevent sticking.

[0032] To achieve the purpose of material mixing, the device adopts the following technical solution: The mixing tank 1 is equipped with two stirring wheels 6 inside, and multiple stirring rods 7 are fixedly sleeved on the outside of the two stirring wheels 6. A fixing ring 8 is fixedly sleeved on the outside of the drive shaft 5. The fixing ring 8 is located between the two stirring wheels 6. Multiple fixing rods 9 are fixedly connected to the outside of the fixing ring 8. Scrapers 10 are fixedly connected to the outer ends of the multiple fixing rods 9. The multiple scrapers 10 are all in contact with the inner wall of the mixing tank 1. Two guide grooves 11 are opened on both sides of the multiple scrapers 10.

[0033] When the user starts the drive motor 4, the drive motor 4 drives the drive shaft 5 and the two stirring wheels 6 to rotate. The rotation of the two stirring wheels 6 drives the multiple stirring rods 7 to rotate and mix the materials.

[0034] To achieve the purpose of preventing adhesion, this device adopts the following technical solution: The anti-adhesion mechanism includes two cover plates 12, both of which are located on the top of the mixing tank 1 and on both sides of the positioning frame 3. Each cover plate 12 has a transmission rod 13 on its top, which is movably connected to the cover plate 12 via rolling bearings. A reciprocating screw 14 is fixedly sleeved on the outer side of each transmission rod 13, and a sleeve 15 is sleeved on the outer side of each reciprocating screw 14. The sleeves 15 are connected to the reciprocating screw 14 via ball screw pairs. Lifting frames 16 are fixedly connected to both sides. Lifting rods 17 are fixedly connected to the bottom of both lifting frames 16. Multiple lifting rods 17 extend to the bottom of both cover plates 12. Scraper strips 18 are provided at the bottom of both cover plates 12. The two scraper strips 18 are fixedly connected to multiple lifting rods 17. A first gear 19 is fixedly sleeved on the outside of the transmission shaft 5. Second gears 20 are provided on both sides of the first gear 19. The two second gears 20 are fixedly sleeved on the outside of the two transmission rods 13. A support frame 21 is fixedly sleeved on the outside of the mixing tank 1. Handles are fixedly connected to the outside of both cover plates 12.

[0035] The rotation of the drive shaft 5 drives the first gear 19 to rotate, which in turn drives the second gear 20 and the drive rod 13 to rotate. The rotation of the drive rod 13 drives the reciprocating screw 14 to rotate, and the rotation of the two reciprocating screws 14 drives the two sleeves 15 to move up and down, thereby driving the lifting frame 16 and the lifting rod 17 to move up and down. The up and down movement of the lifting rod 17 drives the scraper 18 to move up and down, pushing the material on the inner wall above the mixing tank 1 down. At the same time, the rotation of the drive shaft 5 drives the fixed rod 9 and the scraper 10 to rotate, so that the scraper 10 guides and scrapes the material below and the material pushed down above, so that the material falls off completely.

[0036] The usage process of this utility model is as follows: The user puts the material into the mixing bucket 1, closes the two cover plates 12, so that the two second gears 20 mesh with the first gear 19, and starts the transmission motor 4 to work, so that the mixing mechanism mixes the material. At the same time, the anti-sticking mechanism pushes the material down the inner wall of the mixing bucket 1 to prevent sticking. The user starts the transmission motor 4, which drives the transmission shaft 5 and the two stirring wheels 6 to rotate. The rotation of the two stirring wheels 6 drives the multiple stirring rods 7 to rotate to mix the material. The rotation of the transmission shaft 5 will drive the first stirring rod 7 to rotate. When gear 19 rotates, it drives gear 20 and transmission rod 13 to rotate. The rotation of transmission rod 13 drives reciprocating screw 14 to rotate. The rotation of two reciprocating screws 14 drives two sleeves 15 to move up and down, thereby driving lifting frame 16 and lifting rod 17 to move up and down. The up and down movement of lifting rod 17 drives scraper 18 to move up and down, pushing the material on the inner wall above the mixing tank 1 down. At the same time, the rotation of transmission shaft 5 drives fixed rod 9 and scraper 10 to rotate, so that scraper 10 guides and scrapes the material below and the material pushed down above, so that the material falls off completely.

[0037] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
