The five molding boxes 3 are each provided with a molding and demolding structure. The molding and demolding structure includes four sets of concave molds 4, four mounting sleeves 5, four operating rods 6, a movable plate 7, a reset assembly, four mounting blocks 8 and four demolding frames 9;

[0027] The four groups of concave dies 4 are all located on the upper wall of the forming box 3, the four mounting sleeves 5 are embedded on both sides of the upper wall of the forming box 3, the four operating rods 6 are movably embedded in the four mounting sleeves 5, the movable plate 7 is fixedly installed at the bottom end of the four operating rods 6, the reset assembly is installed at the lower end of the forming box 3, and is connected to the lower wall of the movable plate 7, the four mounting blocks 8 are respectively installed on the upper wall of the movable plate 7, the top ends of the four demolding frames 9 are respectively movably embedded in the center of the four groups of concave dies 4, and the bottom ends are respectively connected to the top ends of the four mounting blocks 8.

[0028] In this technical solution, when the sole is injection molded, the staff first moves the device to the specified position, supports the device through the two support frames 2 at the lower end of the fixed plate 1, and then connects the device to the power distribution equipment. By flipping the injection structure to the upper end of the molding box 3, the four operating rods 6 are pushed downward in the four mounting sleeves 5, so that the upper wall surface of the four demolding frames 9 is at the same height as the inner lower wall surface of the four groups of dies 4. Then, the injection molding material is injected into the four groups of dies 4 in the molding box 3 to perform injection molding of the sole. When cooling is completed, the flip injection structure is opened, and under the action of the reset component, the movable plate 7 and the operating rod 6 are pushed to reset, and the four demolding frames 9 are pushed to rise in the four groups of dies 4 through the mounting block 8 to lift the molded sole, thereby realizing automatic demolding operation.

[0029] In some technical solutions, reference Figure 1 , the reset assembly includes four reset rods 10, four reset sleeves 11 and four springs 12;

[0030] One end of the four reset rods 10 is connected to the lower end of the movable plate 7 respectively. The four reset sleeves 11 are all installed on the lower wall of the molding box 3 and are movably sleeved on the bottom ends of the four reset rods 10 respectively. The four springs 12 are movably embedded in the four reset sleeves 11 respectively.

[0031] In this technical solution, the reset sleeve 11 can be used to guide the movement of the four reset rods 10, ensuring the movement stability of the movable plate 7 and the operating rod 6, and the spring 12 located at the lower end of the reset sleeve 11 can apply a thrust to the reset rod 10 during the demolding process, so that the reset rod 10 drives the movable plate 7, the operating rod 6 and the mounting block 8 to move upward.

[0032] In some technical solutions, reference Figure 1 The rear end of the molding box 3 is connected to a flip injection structure, which includes a cover 13, four sets of punches 14, several injection tubes 15, two hinge seats 16 and an electric push rod 17;

[0033] The cover body 13 is installed at the rear end of the forming box body 3 through a hinge. Four sets of punches 14 are installed on the inner wall of the cover body 13. Several injection tubes 15 are embedded in the cover body 13 and are respectively connected to the four sets of punches 14. Two hinge seats 16 are respectively installed on one side of the lower end of the forming box body 3 and one side of the cover body 13. The two ends of the electric push rod 17 are respectively hinged to the two hinge seats 16.

[0034] In this technical solution, during the injection molding process, the electric push rods 17 in the two hinge seats 16 work to flip the cover body 13 to the upper end of the molding box 3, and the operating rod 6 is squeezed through the inner wall of the cover body 13. Then, four groups of punches 14 cooperate with four groups of dies 4, and then the injection molding material is injected between the dies 4 and the punches 14 through several injection pipes 15 to realize the injection molding of the sole. When the sole is cooled, the electric push rods 17 drive the cover body 13 to flip again, and the sole can be demolded.

[0035] In some technical solutions, reference Figure 1 , limit blocks 18 are provided on both sides of the upper end of the fixed plate 1, one of the hinge seats 16 is obliquely installed at the rear end of the cover body 13, the electric push rod 17 adopts a multi-stage electric push rod 17, and the shape of the support frame 2 is a door-shaped support frame 2.

[0036] Working principle:

[0037] When the sole is injection molded, the staff first moves the device to the designated position, supports the device through the two support frames 2 at the lower end of the fixed plate 1, and then connects the device to the power distribution equipment. The electric push rods 17 in the two hinge seats 16 work to flip the cover 13 to the upper end of the molding box 3, and squeeze the operating rod 6 through the inner wall of the cover 13. Then, through the four sets of punches 14 and the four sets of dies 4, the four operating rods 6 are pushed downward in the four mounting sleeves 5, so that the upper wall surface of the four demoulding frames 9 is consistent with the inner lower wall surface of the four sets of dies 4. Then, through several injection pipes 15, the injection material is injected into the dies 4 and the punches 1. 4, injection molding of the sole is realized. After the sole is cooled, the electric push rod 17 drives the cover body 13 to flip over again. Under the action of the reset assembly, the movable plate 7 and the operating rod 6 are pushed to reset, and the four demoulding frames 9 are pushed to rise in the four groups of concave molds 4 through the mounting block 8, and the molded sole is lifted up to realize automatic demoulding operation. The reset sleeve 11 can realize the movement guidance of the four reset rods 10 to ensure the movement stability of the movable plate 7 and the operating rod 6, and the spring 12 located at the lower end of the reset sleeve 11 can apply thrust to the reset rod 10 during the demoulding process, so that the reset rod 10 drives the movable plate 7, the operating rod 6 and the mounting block 8 to move upward.
