A rotary table is rotatably mounted on the top of the base. Multiple annularly distributed support seats are provided on the top of the rotary table. An installation groove is opened on the top of each support seat. The injection mold is installed in the installation groove. The injection molding machine is located on one side of the rotary table. A discharge port is provided at the bottom of the injection molding machine. A vertically arranged cylinder is provided below the side of the rotary table near the injection molding machine. A through hole is opened below each support seat on the rotary table.

[0007] The injection mold has a positioning groove on one side, and the support base has a groove on one side of the mounting groove. A positioning block slides through the groove and the mounting groove. A spring is installed inside the groove, and a movable block is abutted against the top of the spring. A guide groove is provided on the inner wall of the movable block. A guide block is fixedly connected to one end of the positioning block, and the guide block slides in the guide groove.

[0008] In a preferred embodiment, a motor for driving the turntable to rotate is fixedly installed inside the base.

[0022] Please see Figure 1-3 This utility model provides a rotary shoe sole injection molding device, including a base 1, an injection mold 2, and an injection molding machine 3. A turntable 11 is rotatably mounted on the top of the base 1. A motor for driving the turntable 11 to rotate is fixedly installed inside the base 1. Multiple annularly distributed support seats 12 are provided on the top of the turntable 11. The top of the support seats 12 has an installation groove 13. The injection mold 2 is installed in the installation groove 13. The top of the injection mold 2 has an injection port 22. The injection molding machine 3 is located on one side of the turntable 11. The bottom of the injection molding machine 3 has a discharge port. A vertically arranged cylinder 4 is provided below the side of the turntable 11 near the injection molding machine 3. The turntable 11 has a cylinder 4 located below each support seat 12. Through hole 41, with the setup of machine base 1, injection mold 2 and injection molding machine 3, during injection, the start motor drives the turntable 11 to rotate, the turntable 11 rotates the injection mold 2 to be injected to below the discharge port of injection molding machine 3, then the piston rod of cylinder 4 is extended, so that the piston rod of cylinder 4 presses against the support seat 12 to lift the injection mold 2, so that the discharge port of injection molding machine 3 connects with the injection port 22 of injection mold 2 for injection. After the injection is completed, the piston rod of cylinder 4 is retracted, so that the support seat 12 drives the injection mold 2 to descend, and then the motor is started again to drive the turntable 11 to rotate, so that the other injection molds 2 are rotated one by one to below the discharge port of injection molding machine 3 for injection, reducing manual operation.

[0023] The support base 12 is slidably connected to each of its four corners with a guide rod 110. The lower end of the guide rod 110 is fixedly connected to the turntable 11. The guide rod 110 guides the support base 12 when it is raised or lowered, ensuring the stability of the support base 12.

[0024] Reference Figure 2 and Figure 3A positioning groove 21 is provided on one side of the injection mold 2. A groove 14 is provided on one side of the support base 12 located in the mounting groove 13. A positioning block 15 slides through the groove 14 and the mounting groove 13. The positioning block 15 is angled towards the opening of the mounting groove 13. A spring 16 is provided inside the groove 14. The top of the spring 16 abuts against a movable block 17. A guide groove 18 is provided on the inner wall of the movable block 17. A guide block 19 is fixedly connected to one end of the positioning block 15. The guide block 19 slides in the guide groove 18 and passes through the positioning groove 21. 1. The positioning block 15, spring 16, movable block 17, guide groove 18 and guide block 19 are configured such that the spring 16 can push the movable block 17 up, so that the movable block 17 can drive the positioning block 15 into the positioning groove 21 to position the injection mold 2. When the injection mold 2 needs to be replaced, the movable block 17 can be pressed down, so that the movable block 17 can drive the guide block 19 to slide in the guide groove 18, so that the guide block 19 can drive the positioning block 15 to move out of the positioning groove 21, and the injection mold 2 can be disassembled for replacement, which is convenient for the replacement of the injection mold 2.

[0025] The inner wall of the groove 14 is provided with a limiting block 111, and the movable block 17 is provided with a limiting groove 112 on the side away from the positioning block 15. The limiting block 111 and the limiting groove 112 are slidably connected. Through the cooperation of the limiting block 111 and the limiting groove 112, the movable block 17 can be limited.

[0026] The working principle and usage process of this utility model are as follows: First, during injection molding, the starter motor drives the turntable 11 to rotate, and the turntable 11 rotates the injection mold 2 to be injected to below the discharge port of the injection molding machine 3. Then, the piston rod of the cylinder 4 is extended, causing the piston rod of the cylinder 4 to press against the support seat 12 and lift the injection mold 2, so that the discharge port of the injection molding machine 3 aligns with the injection port 22 of the injection mold 2 for injection. After the injection is completed, the piston rod of the cylinder 4 is retracted, causing the support seat 12 to lower the injection mold 2. Then, the motor is started again to drive the turntable 11 to rotate, rotating the other injection molds 2 one by one to the injection molding machine 3. Injection molding is performed below the discharge port, reducing manual operation. Through the setting of positioning groove 21, positioning block 15, spring 16, movable block 17, guide groove 18 and guide block 19, the spring 16 can push the movable block 17 to rise, so that the movable block 17 drives the positioning block 15 to be inserted into the positioning groove 21 to position the injection mold 2. When the injection mold 2 needs to be replaced, the movable block 17 can be pressed down, so that the movable block 17 drives the guide block 19 to slide in the guide groove 18, so that the guide block 19 drives the positioning block 15 to move out of the positioning groove 21, and the injection mold 2 can be disassembled for replacement, which is convenient for the replacement of the injection mold 2.
