A bottom of the cold water tank 31 is fixedly connected with a bottom of an inner cavity of the first mounting frame 11. A circulating pipe 32 that communicates cooling channels in a plurality of first molds 21 with an inside of the cold water tank 31 is arranged on one side of the cold water tank 31. A circulating pump 33 is arranged inside the circulating pipe 32.

[0018] In this embodiment, when injecting slippers, according to the styles and colors of the slippers to be injected, appropriate plastic particles are selected and placed into the hopper 13. Subsequently, the motor 14 is started to drive the spiral blade 15 to rotate, and the raw materials in the hopper 13 are conveyed into the injection barrel 12. Under the action of the first heater 16, the plastic in the injection barrel 12 is heated to melt it. Subsequently, under the action of the spiral blade 15, the raw materials are conveyed into the distribution barrel 17. The raw materials are distributed by the distribution barrel 17. At the same time, under the action of the second heater 18, the raw materials in the distribution barrel 17 are continuously heated to maintain the fluidity of the raw materials. Subsequently, the solenoid valve 110 is opened, and the raw materials enter the inner cavities of the first mold 21 and the second mold 27 along the injection pipe 19. Embodiment 2

[0019] As Figures 1-8As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the injection mechanism further includes a spiral blade 15 disposed on the surface of the rotating shaft of the motor 14. A first heater 16 is provided on the surface of the injection barrel 12. One end of the injection barrel 12 communicates with a flow dividing barrel 17. A second heater 18 is provided on the surface of the flow dividing barrel 17. An injection pipe 19 is provided on one side of the flow dividing barrel 17. A solenoid valve 110 is provided inside the injection pipe 19. The molding mechanism further includes a mounting plate 24. The inside of the mounting plate 24 is fixedly connected to the inside of the sliding rod 22. One side of the mounting plate 24 is fixedly connected to a hydraulic cylinder 25. The output end of the hydraulic cylinder 25 is fixedly connected to a second mounting bracket 26. One end of the second mounting bracket 26 is fixedly connected to a second mold 27. A ejector rod 28 is inserted into the second mold 27. One end of the ejector rod 28 is fixedly connected to a contact plate 29. One side of the contact plate 29 abuts against one side of the ejector plate 23. A spring 210 is sleeved on the surface of the ejector rod 28. The cooling mechanism further includes a thermoelectric cooler 34 and a blower 35. The heat absorption end of the thermoelectric cooler 34 is disposed inside the cold water tank 31. The heat dissipation end of the thermoelectric cooler 34 is disposed on the side away from the heat absorption end. The blower 35 is provided on the inner wall of the first mounting bracket 11.

[0020] In this embodiment, after the slipper is solidified and molded, the hydraulic cylinder 25 pulls the second mounting bracket 26 to make the second mold 27 slide along the surface of the sliding rod 22 to open the mold. After pulling and sliding a certain distance, the contact plate 29 contacts the ejector plate 23. Blocked by the ejector plate 23, the ejector rod 28 stops moving. While ejecting the slipper in the second mold 27, the second mold 27 continues to move to compress the spring 210, so that the slipper falls into the first mounting bracket 11 along the opening on the surface of the first mounting bracket 11. Subsequently, the hydraulic cylinder 25 pushes the second mold 27 to reset. Under the action of the elastic force of the spring 210, the ejector rod 28 is pushed to reset. During the process of shaping and opening the mold of one molding mechanism, the other solenoid valves 110 are opened to inject raw materials into the other molding mechanisms to fill the waiting time for shaping and opening the mold of the molding mechanism, avoiding the idle state of other workstations, improving the utilization rate of the equipment, and thus improving the production efficiency. Embodiment 3

[0021] As Figures 1-8 shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, S1: Raw material preparation: According to the color, material, and performance requirements of the slipper, put the plastic raw material into the feeding hopper 13; S2: Station initialization: Initialize each injection station through the control system, including adjusting the opening and closing positions of the mold, setting the temperature and pressure of the injection barrel, and calibrating the metering device; S3: Raw material supply: According to the requirements of each station, transport the raw material to the injection barrel 12 through the conveying pipeline. During the transportation process, the raw material is heated and melted in the injection barrel 12; S4: Injection molding: When the raw material reaches the appropriate temperature and fluidity, the spiral blade 15 injects the molten raw material into the flow dividing cylinder 17 driven by the motor 14. The control system precisely controls the opening of the solenoid valve 110 according to the mold size and shape of each station, and injects the raw material into each station: S5: Cooling and shaping; After the injection molding is completed, the cooling mechanism starts to work. Through the circulating flow of the cooling medium, the mold and the molded slippers are quickly cooled. The cooling time is precisely controlled according to the material and size of the slippers to ensure that the slippers are fully cooled and shaped; S6: Mold opening and demolding: When the cooling time reaches the set value, the hydraulic cylinder 25 drives the mold to open, and the ejector rod 28 ejects the molded slippers from the mold.

[0022] In this embodiment, after the injection is completed, under the action of the circulating pump 33, cold water continuously flows through the inside of the first mold 21 through the circulation pipe 32, accelerating the solidification and molding speed of the slippers. At the same time, during the circulation of the cold water, the semiconductor cooler 34 continuously transfers the heat at the heat absorption end to the heat dissipation end, thereby continuously cooling the water in the cold water tank 31. At the same time, during the cooling process, the blower 35 accelerates the flow rate of the air on the surface of the heat dissipation end of the semiconductor cooler 34, thereby performing air cooling on it, reducing the temperature difference between the heat absorption end and the heat dissipation end, and improving the refrigeration effect.

[0023] Next, the working principle of the multi-station linkage slipper injection molding equipment and its process will be specifically described.

[0024] As Figures 1-8As shown in the figure, when injecting plastic slippers, appropriate plastic particles are selected according to the style and color of the plastic slippers to be injected, and they are placed into the feeding hopper 13. Subsequently, the motor 14 is started to drive the spiral blade 15 to rotate, and the raw materials in the feeding hopper 13 are transported into the injection barrel 12. Under the action of the first heater 16, the plastic in the injection barrel 12 is heated to melt it. Subsequently, under the action of the spiral blade 15, the raw materials are transported into the shunt barrel 17, and the raw materials are shunted through the shunt barrel 17. At the same time, under the action of the second heater 18, the raw materials in the shunt barrel 17 are continuously heated to maintain the fluidity of the raw materials. Subsequently, the solenoid valve 110 is opened, and the raw materials enter the inner cavities of the first mold 21 and the second mold 27 along the injection pipe 19. After the injection is completed, under the action of the circulating pump 33, cold water continuously flows through the inside of the first mold 21 through the circulating pipe 32 to accelerate the solidification and molding speed of the slippers. At the same time, during the process of the cold water circulating, the semiconductor refrigerator 34 continuously transfers the heat at the heat absorption end to the heat dissipation end, thereby continuously cooling the water in the cold water tank 31. At the same time, during the cooling process, the air blower 35 accelerates the flow rate of the air on the surface of the heat dissipation end of the semiconductor refrigerator 34, thereby performing air cooling on it, reducing the temperature difference between the heat absorption end and the heat dissipation end, and improving the refrigeration effect. After the slippers are solidified and molded, the hydraulic cylinder 25 pulls the second mounting bracket 26 to make the second mold 27 slide along the surface of the sliding rod 22 to open the mold. After pulling and sliding a certain distance, the contact plate 29 contacts the ejector plate 23. Under the block of the ejector plate 23, the ejector rod 28 stops moving. While ejecting the slippers in the second mold 27, the second mold 27 continues to move to compress the spring 210, so that the slippers fall into the first mounting bracket 11 along the opening on the surface of the first mounting bracket 11. Subsequently, the hydraulic cylinder 25 pushes the second mold 27 to reset. Under the elastic force of the spring 210, the ejector rod 28 is pushed to reset. During the process of a molding mechanism being shaped and opened, the other solenoid valves 110 are opened to inject raw materials into the other molding mechanisms to fill the waiting time for the molding mechanism to be shaped and opened, avoiding the idle state of other workstations, improving the utilization rate of the equipment, and thus improving the production efficiency.

[0025] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
