Claims

1. A novel coiled tooth mold structure, characterized in that: The system includes an A-mold assembly, a B-mold assembly, and a central core mold assembly located between the A-mold assembly and the B-mold assembly. The central core mold assembly contains several coilover core mold assemblies. Each coilover core mold assembly includes a threaded core mold, a first end core mold, a coilover inner cavity forming mold pillar, a sliding outer sleeve, a gear outer sleeve, and a bushing. The bushing is fixed within the central core mold assembly. The gear outer sleeve is rotatably connected within the bushing. The sliding outer sleeve slides within the gear outer sleeve and rotatably fits onto the outside of the first end core mold. The threaded core mold is fixed within the sliding outer sleeve and located at the end of the first end core mold facing the B-mold assembly. The coilover inner cavity forming mold pillar is located within the first end core mold and includes an inner cavity forming prism extending into the threaded core mold. The first end core mold and the coilover inner cavity forming mold pillar are connected to the A-mold assembly. The central core mold assembly has a drive mechanism for rotating the gear outer sleeve. The B-mold assembly has a second end core mold located at the end of the threaded core mold away from the first end core mold.

2. The novel coilover mold structure according to claim 1, characterized in that: A coiled tooth end pressure sleeve is fixedly connected to the inner cavity forming mold column of the coiled tooth. The end of the coiled tooth end pressure sleeve facing the threaded part core mold includes several tooth-shaped molds. A coiled tooth cavity is formed between the threaded part core mold, the first end core mold, the inner cavity forming mold column of the coiled tooth, the second end core mold, and the coiled tooth end pressure sleeve. The B mold assembly is provided with a casting channel leading to the coiled tooth cavity.

3. The novel coilover mold structure according to claim 1, characterized in that: A hinge seat is fixedly connected to the outside of the A-mold assembly. A swing rod is rotatably connected to the hinge seat. A hook block is fixedly connected to the end of the swing rod away from the hinge seat. A hook groove is opened on the side of the B-mold assembly near the central core template for the hook block to enter. When the hook block is in the hook groove, it abuts against the side of the central core template facing the B-mold assembly. An elastic pressure plate is provided on the hinge seat for pressing against the swing rod.

4. The novel coilover mold structure according to claim 3, characterized in that: A long rod seat is fixedly connected to the B-mold assembly. The long rod seat extends to the outer surface of the central core template and is fixedly connected to an inclined guide block. A round rod is fixedly connected to the hook block, and the round rod extends to the outer side of the long rod seat.

5. The novel coiled tooth mold structure according to claim 1, characterized in that: The drive mechanism includes a geared motor, a drive gear, a driven gear, and a transmission gear. A motor mounting base is fixedly connected to the outer side of the central core template. The geared motor is fixed on the motor mounting base and its output shaft is connected to the drive gear. The driven gear is rotatably connected to the motor mounting base and meshes with the drive gear. The transmission gear is rotatably connected to the central core template and meshes with the driven gear. The transmission gear and the gear sleeve are in a transmission engagement.

6. The novel coiled tooth mold structure according to claim 5, characterized in that: The coiled tooth core mold assembly is provided in four parts, of which the gear sleeves of two coiled tooth core mold assemblies mesh with the transmission gears. The central core mold plate is rotatably connected with two transition gears, which are respectively meshed between the two gear sleeves that mesh with the transmission gears and the two gear sleeves that do not mesh with the transmission gears.

7. The novel coiled tooth mold structure according to claim 1, characterized in that: The outer wall of the sliding sleeve is provided with an axially oriented sliding groove, and the gear sleeve is provided with a spherical retainer with a spherical retainer on which a spherical ball is provided, and the spherical ball is movably fitted on the sliding groove.
