On the outer wall of the rotating shaft 11, there are stirring rods 12 for stirring and driving the injection materials in the stirring tank 8. The injection materials in the injection molding machine 5 are heated by the heating wire 6 to prevent the injection materials from cooling in the injection molding machine 5 and affecting subsequent injection operations.

[0027] At the end of the support plate 3, a support frame 14 is fixedly installed. At both ends of the support frame 14, two symmetrically arranged support vertical plates 15 are fixedly installed. On the side wall of the support vertical plate 15, an electric push rod 16 is fixedly installed. At the end of the electric push rod 16, a rectangular moving plate 17 is fixedly installed. On the side wall of the moving plate 17, two symmetrically arranged suction cups 18 are fixedly installed. In the suction cup 18, a circular sealing ring 20 that is in close contact with the inner wall of the suction cup 18 is slidably arranged, and in the suction cup 18, a first chamber 21 and a second chamber 22 separated by the sealing ring 20 are provided.

[0028] The injection mold 23 is slidably arranged on the support frame 14, and on the injection mold 23, a first cooling port 26 communicating with the inverted U-shaped cooling cavity 25 is provided.

[0031] The functional principle of the present utility model can be described through the following operation methods:

[0032] During use, injection molding materials are injected into the mixing tank 8 through the injection port 10. Then, by turning on the servo motor 9, the servo motor 9 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the stirring rod 12 to fully stir the injection molding materials. Then, the injection molding materials flow into the conveying roller 7.

Then, through the telescoping of the electric telescopic rod 27, the first cooling port 26 and the second cooling port 30 are closely attached. Then, the water pump 31 pumps the coolant in the collection tank 35 into the inverted U-shaped cooling cavity 25 through the conveying pipe 32 to quickly cool the toy building blocks in the injection cavity 24. After cooling, the coolant will flow from the inverted U-shaped cooling cavity 25 into the telescopic hose 33 and finally be discharged into the collection tank 35 through the drain port 34;

[0033] When different injection molding templates 23 need to be replaced, by turning on the hydraulic rod 19, the hydraulic rod 19 pushes the sealing ring 20 to move towards the first chamber 21, making the atmospheric pressure in the first chamber 21 higher than the atmospheric pressure in the air. Under the action of the pressure difference, the suction cup 18 releases the limit on the injection molding template 23, facilitating the quick replacement of different injection molding templates 23. After replacement, by turning on the electric push rod 16, the electric push rod 16 pushes the moving plate 17 towards the injection molding template 23, making the end of the suction cup 18 closely attached to the injection molding template 23. Then, through the telescoping of the hydraulic rod 19, the hydraulic rod 19 pulls the sealing ring 20 towards the second chamber 22, making the atmospheric pressure in the first chamber 21 lower than the atmospheric pressure in the air. Through the pressure difference, the suction cup 18 is fixed on the side wall of the injection molding template 23, facilitating the demolding process of the toy building blocks after cooling.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
