[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 3 As shown, this utility model is an injection molding machine for processing two-color covers of a washer-dryer, including a cabinet 1, a support plate 2 on the cabinet 1, a rotating disk 4 on one side of the support plate 2, two symmetrical molds 5 on the rotating disk 4, and a limiting mechanism between the molds 5 and the rotating disk 4 for the replacement and maintenance of the molds 5. The limiting mechanism includes a limiting block 7 fixed to the end of the mold 5. The limiting block 7 has a limiting groove 6 corresponding to the rotating disk 4, and the limiting block 7 is located within the limiting groove 6. A cross block 8 is fixed to the end of the limiting block 7 away from the mold 5. A fixing groove corresponding to the cross block 8 is opened on the rotating disk 4, and the cross block 8 is located within the fixing groove. Two symmetrical limiting posts 9 are slidably arranged on one side of the cross block 8. Two fixing holes are opened on the cross block 8. The limiting posts 9 extend out of the rotating disk 4 and into the fixing holes. A spring 10 is fixed to one end of the limiting post 9. The end of the spring 10 away from the limiting post 9 is fixedly connected to the rotating disk 4. A movable post 11 is fixed to the end of the limiting post 9. The movable post 11 is located within the spring 10 and extends out of the rotating disk 4, and is fixedly connected to a connecting plate 12. The ends of the cross block 8 and the limiting posts 9 are both arc-shaped and correspond to each other.

[0020] Specifically, the two molds 5 facilitate the production of two-color caps, and the limiting mechanism facilitates the replacement and maintenance of the molds 5, improving the efficiency of mold replacement, facilitating the production of two-color caps of different sizes, facilitating the continuous production of two-color caps, and reducing the impact on production efficiency. Specifically, when it is necessary to change the mold 5 to a different size, pull the two connecting plates 12 to move the two moving columns 11, which in turn moves the limiting column 9, causing the spring 10 to extend and retract, thus releasing the restriction on the mold 5. Pull the mold 5 to disengage the limiting block 7 and the cross block 8 from the rotating disk 4, facilitating the replacement and maintenance of the mold 5. Then, insert the limiting block 7 of the new mold 5 into the limiting groove 6, so that the cross block 8 enters the fixing groove. The cross block 8 is adapted to the fixing groove, and the arc-shaped end of the cross block 8 moves to abut against the arc-shaped end of the limiting column 9, causing the limiting column 9 to move. The spring 10 extends and retracts. When the limiting column 9 corresponds to the fixing hole, the elasticity of the spring 10 causes the limiting column 9 to enter the fixing hole, restricting the mold 5. The limiting effect of the limiting column 9 is strengthened by the moving column 11, which facilitates the replacement and maintenance of the mold 5 and reduces the impact on the production efficiency of the two-color cap.

[0021] In this embodiment, refer to Figure 3 - Figure 5 As shown, a water tank 3 is fixed inside the cabinet 1. A cabinet door is hinged to one side of the cabinet 1, and a panel is hinged to the water tank 3. A drain pipe is fixed to one end of the water tank 3, and a valve is installed inside the drain pipe. A water pump 18 is fixed to one side of the water tank 3, and an inlet pipe 19 is fixed to the outlet end of the water pump 18. The inlet pipe 19 extends out of the cabinet 1 and into the mold 5, where it is fixedly connected to the cooling pipe 20. An outlet pipe 21 is fixed to the end of the cooling pipe 20 away from the inlet pipe 19. The two molds 5 are connected by a connecting pipe. The outlet pipe 21 extends into the cabinet 1 and into the water tank 3. Both the inlet pipe 19 and the outlet pipe 21 are polyurethane flexible hoses, and the cooling pipes 20 are arranged in a spiral array. A semiconductor cooling chip 22 is fixed to one end of the water tank 3. The cooling end of the semiconductor cooling chip 22 extends into the water tank 3 and is fixedly connected to multiple conductive plates 23. The heating end of the semiconductor extends out of the water tank 3. A fan 24 is provided on one side of the water tank 3. A ventilation pipe is fixed to one end of the fan 24 and is fixedly connected to the water tank 3. The semiconductor cooling chip 22 corresponds to the ventilation pipe. An air outlet pipe is fixed to the output end of the fan 24 and extends out of the cabinet 1.

[0022] Specifically, open the cabinet door, then open the box panel, add an appropriate amount of water to the water tank 3, and run the water pump 18 to draw water from the water tank 3. The water enters the inlet pipe 19 from the outlet of the water pump 18, and then enters the cooling pipe 20 through the inlet pipe 19. The cooling pipe 20 is arranged in a spiral array to increase the contact time with the mold 5, improve the cooling effect on the mold 5, and facilitate the rapid molding of the mold 5. The water that has absorbed heat flows back into the water tank 3 through the outlet pipe 21, facilitating water recycling. The water outlet pipe 21 is a polyurethane flexible hose, which is convenient to move with the mold 5. At the same time, the semiconductor cooling chip 22 is operated to cool the water in the water tank 3, which improves the cooling effect on the mold 5. Multiple conduction plates 23 transfer heat into the water in the water tank 3, which facilitates the cooling of the water and improves the cooling effect on the mold 5, which facilitates the rapid molding of the mold 5. At the same time, the fan 24 is operated to discharge the heat generated by the semiconductor cooling chip 22 to the cabinet 1 through the air outlet pipe. The water is discharged by opening the drain valve.

[0023] In this embodiment, refer to Figure 1 and Figure 5 As shown, an electric track 13 is fixed on the cabinet 1, a support plate 2 is located on the electric track 13, a servo motor 14 is fixed on the support plate 2, the output end of the servo motor 14 passes through the support plate 2 and is fixedly connected to the rotating disk 4, an injection molding module 15 is fixed on the side of the cabinet 1 away from the rotating disk 4, two fixed molds 16 are fixed on the injection molding module 15, an injection head 17 is fixed on the fixed mold 16, and the fixed mold 16 corresponds to the mold 5.

[0024] Specifically, the injection molding module 15 heats and melts the injection molding material, which is then fed into the injection head 17 on the fixed mold 16. At the same time, the electric track 13 is operated to make the mold 5 fit with the fixed mold 16. The injection head 17 injects one color into the mold 5. After completion, the motor is operated to make the rotating disk 4 drive the mold 5 to rotate 180 degrees, so that the other injection head 17 injects a second color into the mold 5, completing the injection of the two-color cap. The two-color cap is then removed, and the rotating disk 4 is reset for the next injection.

[0025] The working principle of this utility model is as follows: The injection module 15 heats and melts the injection material, and then the material is fed into the injection head 17 on the fixed mold 16. At the same time, the electric track 13 is operated so that the mold 5 fits into the fixed mold 16. The injection head 17 injects one color into the mold 5. After completion, the motor is operated so that the rotating disk 4 drives the mold 5 to rotate 180 degrees, so that the other injection head 17 injects a second color into the mold 5, completing the injection of the two-color cap. The two-color cap is removed, and then the rotating disk 4 is reset for the next injection. Then, when it is necessary to change to a mold 5 of a different size, pull the two connecting plates 12 to move the two moving columns 11, which in turn moves the limiting column 9, causing the spring 10 to extend and retract, thus releasing the restriction on the mold 5. Pull the mold 5 to make the limiting block 7 and the cross block 8 separate from the rotating disk 4, which facilitates the replacement and maintenance of the mold 5. Then, insert the limiting block 7 of the new mold 5 into the limiting groove 6, so that the cross block 8 enters the fixing groove. The cross block 8 is adapted to the fixing groove, and the arc-shaped end of the cross block 8 moves to abut against the arc-shaped end of the limiting column 9, causing the limiting column 9 to move. The spring 10 extends and retracts. When the limiting column 9 corresponds to the fixing hole, the elasticity of the spring 10 causes the limiting column 9 to enter the fixing hole, thus restricting the mold 5. Then, open the cabinet door and the box panel, add an appropriate amount of water to the water tank 3, and run the water pump 18 to draw water from the water tank 3. The water enters the inlet pipe 19 from the outlet of the water pump 18 and then enters the cooling pipe 20 through the inlet pipe 19. The cooling pipe 20 is arranged in a spiral array to increase the contact time with the mold 5, improve the cooling effect on the mold 5, and facilitate the rapid molding of the mold 5. The water that absorbs heat flows into the water tank 3 through the outlet pipe 21 to facilitate water recycling. The inlet pipe 19 and the outlet pipe 21 are made of polyurethane hoses, which are easy to move with the mold 5. At the same time, run the semiconductor cooling chip 22 to cool the water in the water tank 3 and improve the cooling effect on the mold 5. Multiple conduction plates 23 transfer heat into the water in the water tank 3 to facilitate water cooling and improve the cooling effect on the mold 5, which facilitates the rapid molding of the mold 5.
