[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 A one-piece molding mold for shoe soles includes an injection frame 1, a movable seat 2 inside the injection frame 1, and a first mold 3 and a second mold 4 respectively fitted onto the bottom of the injection frame 1 and the opposite sides of the movable seat 2. A third mold 5 and a fourth mold 6 respectively fitted onto the top of the injection frame 1 and the opposite sides of the movable seat 2. The upper part of the injection frame 1 is provided with a telescopic device 7 for driving the movable seat 2 to move up and down, and a storage box 8 for storing material. A flexible connecting hose 9 connects the storage box 8 and the movable seat 2. The connecting hose 9 conveys the material to the second mold 4 or the third mold 5. The telescopic device 7 has a connecting plate 10 fixedly installed at the upper end of its telescopic extension. The connecting plate 10 has connecting columns 11 fixedly installed at the lower parts of both ends. The lower end of the connecting column 11 passes through the injection frame 1 and is used to drive the moving seat 2 to move. The connecting hose 9 has a connecting injection tube 19 fixedly installed at one end inside the moving seat 2. The injection tube 19 connects the second mold 4 and the third mold 5. The sides of both ends of the injection tube 19 are fixedly installed with electromagnetic valves 20 for opening and closing the injection tube 19.

[0030] Specifically, during the injection molding of the shoe sole, the first mold 3 and the second mold 4 are respectively installed on the bottom of the injection frame 1 and the opposite side of the movable seat 2. The third mold 5 and the fourth mold 6 are respectively installed on the top of the injection frame 1 and the opposite side of the movable seat 2. The telescopic device 7 is activated, and the telescopic end of the telescopic device 7 moves down, driving the connecting column 11 to move down through the connecting plate 10. The connecting column 11 drives the movable seat 2 to move down. At this time, the first mold 3 and the second mold 4 are combined. The material pump in the storage tank 8 is turned on, and the injection molding material is transported to the injection tube 19 through the connecting hose 9. The solenoid valve 20, which is adapted to the position of the second mold 4, is turned on, and the injection molding material is transported to the cavity of the first mold 3 and the second mold 4 to form the shoe sole. When the first mold After the soles in molds 3 and 4 are formed, the telescopic end of the telescopic device 7 moves upward, driving the moving seat 2 to move upward until the third mold 5 and the fourth mold 6 merge. The electromagnetic valve 20 adapted to the third mold 5 is then opened to deliver injection molding material into the cavities of the third mold 5 and the fourth mold 6. During this process, the operator removes the formed soles from the first mold 3 and cleans the first mold 3 and the second mold 4, spraying a release agent. After the soles in the third mold 5 and the fourth mold 6 are formed, the moving seat 2 moves downward again. The operator removes the formed soles from the third mold 5, cleans the third mold 5 and the fourth mold 6 again, and sprays a release agent. This dual-station sole forming improves the efficiency of sole production.

[0031] As a technical optimization of this utility model, two positioning plug-in rods 13 are passed through the upper and lower sides of the injection molding frame 1 and the opposite sides of the movable seat 2. The opposite sides of the first mold 3, the second mold 4, the third mold 5 and the fourth mold 6 are all provided with positioning holes 14 that are adapted to the ends of the positioning plug-in rods 13. A pull plate 16 is fixedly installed between the ends of the two positioning plug-in rods 13. An elastic element 15 with elasticity is sleeved on the side of the positioning plug-in rod 13. One end of the elastic element 15 is fixed to one side of the pull plate 16, and the other end of the elastic element 15 is fixedly installed to the side of the injection molding frame 1 or the side of the movable seat 2.

[0032] Specifically, when installing the first mold 3, the second mold 4, the third mold 5, and the fourth mold 6, two symmetrical pull plates 16 are pulled in opposite directions. At this time, the elastic element 15 is stretched, and the first mold 3, the second mold 4, the third mold 5, and the fourth mold 6 are engaged in the slots on the bottom, lower part, upper part of the moving seat 2, and top of the injection molding frame 1. At this time, the positioning hole 14 is aligned with the end of the positioning plug rod 13. When the pull plate 16 is released, the elastic element 15 retracts, driving the positioning plug rod 13 to move. One end of the positioning plug rod 13 is inserted into the positioning hole 14, thereby fixing the first mold 3, the second mold 4, the third mold 5, or the fourth mold 6, which facilitates the installation or subsequent replacement of the first mold 3, the second mold 4, the third mold 5, and the fourth mold 6. The elastic element 15 can be a spring.

[0033] As a technical optimization of this utility model, the ends of the two connecting columns 11 extending into the injection molding frame 1 are each fixedly installed with sliding blocks 12. The opposite sides of the injection molding frame 1 are provided with sliding grooves 21 that are adapted to the sliding blocks 12. When the connecting column 11 moves, it drives the sliding block 12 to move in the sliding groove 21. The cooperation between the sliding block 12 and the sliding groove 21 limits the movement of the moving seat 2 and improves the stability of the moving seat 2 when it moves.

[0034] As a technical optimization of this utility model, several positioning pins 17 are fixedly installed on the lower part of the second mold 4 and the fourth mold 6. Several positioning grooves 18 adapted to the positioning pins 17 are opened on the upper part of the first mold 3 and the third mold 5. The positioning pins 17 have a trapezoidal cross-section. The positioning grooves 18 are adapted to the positioning pins 17, and the diameter of the end of the positioning pin 17 facing the positioning groove 18 is smaller than the diameter of the end away from the positioning groove 18. When the first mold 3 and the second mold 4 are combined or the third mold 5 and the fourth mold 6 are combined, several positioning pins 17 are inserted into the positioning grooves 18. The positioning pins 17 have a trapezoidal cross-section. The positioning grooves 18 are adapted to the positioning pins 17, which improves the accuracy after the first mold 3 and the second mold 4 are combined or the third mold 5 and the fourth mold 6 are combined.
