[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] A die-casting apparatus for wheel rim blanks includes: a frame 10, a mold assembly 20, a pressure feeding assembly 30, and a cooling assembly 40.

[0024] The frame 10 serves as the frame and support for the die-casting device.

[0025] The mold assembly 20 is used for forming the rough blank of the wheel rim. It is mounted on the frame 10 and includes a first side mold 201 and a second side mold 202 arranged horizontally and symmetrically, an upper mold 203 located above the first side mold 201 and the second side mold 202, a lower mold 204 located below the first side mold 201 and the second side mold 202, and a mold core 205 fixedly mounted on the upper end of the upper mold 203. The first side mold 201 and the second side mold 202 are both arc-shaped and form a ring shape when closed. The upper mold 203 and the lower mold 204 respectively abut against the upper and lower ends of the closed first side mold 201 and the second side mold 202. The first side mold 201 and the second side mold 202 are driven to move by a horizontal propulsion mechanism 206, and the upper mold 203 and the lower mold 204 are driven to rise and fall by a first lifting mechanism 207 and a second lifting mechanism 208, respectively. The mold core 205 includes a cylindrical boss 2051 fixed to the upper end of the upper mold 203. A cylindrical central rod 2053 is fixedly provided at the center of the upper end of the cylindrical boss 2051, and a plurality of spoke rods 2052 are provided around the central rod 2053. After the first side mold 201, the second side mold 202, the upper mold 203 and the lower mold 204 are closed, there is a gap between the inner wall of the first side mold 201 and the second side mold 202 and the cylindrical boss 2051 for forming a tire seat for the steel rim. The upper end of the cylindrical boss 2051 does not contact the upper mold 203, leaving space for forming spokes and hub. The upper ends of the central rod 2053 and the spoke rods 2052 abut against the upper mold 203, thereby forming spokes in the gaps between the plurality of spoke rods 2052 and forming a wheel rim in the gaps between the central rod 2053 and the plurality of spoke rods 2052.

[0026] The pressure feeding assembly 30 is used to inject molten material into the mold assembly 20 by pressure and is connected to the upper end of the upper mold 203.

[0027] The cooling component 40 is used to rapidly cool the formed wheel rim blank.

[0028] Before die casting, the first side mold 201 and the second side mold 202 move towards each other and close into a ring shape under the drive of two horizontal propulsion mechanisms 206. Then, the upper mold 203 and the lower mold 204 are pressed against the upper and lower ends of the upper mold 203 and the lower mold 204 respectively under the drive of the first lifting mechanism 207 and the second lifting mechanism 208, forming a closed die casting space. The mold core 205 is located in this die casting space. Then, the pressure feeding assembly 30 injects material into the die casting space under pressure, filling the gaps in the die casting space to form a steel ring blank. Then, the cooling assembly 40 rapidly cools the steel ring blank, allowing it to cool and solidify quickly. This can speed up production efficiency and avoid burns from high temperatures when manually removing the steel ring.

[0029] In a preferred embodiment, the cooling component 40 includes an inlet 401 and an outlet 402 disposed on the outer wall of the first side mold 201. The inlet 401 and the outlet 402 are respectively connected to a cooling water tank 405 via an inlet pipe 403 and an outlet pipe 404. The cooling water tank 405 is connected to a cooling component. A submersible pump 407 is disposed inside the cooling water tank 405. The submersible pump 407 is connected to the inlet pipe 403. The first side mold 201 and the second side mold 202 are provided with a piping system that connects to the inlet 401 and the outlet 402 to form a loop.

[0030] The cooling water tank 405 contains cooling water. The water is cooled by the cooling components. Then, under the action of the submersible pump 407, the water is sent into the piping system in the first side mold 201 and the second side mold 202 through the water inlet pipe 403, thereby cooling the steel ring blank in the die-casting space. Then, the water is discharged from the water outlet pipe 404 back to the cooling water tank 405. The water is circulated through this loop, thereby continuously cooling the water.

[0031] In a preferred embodiment, the piping system includes a first insertion tube 4081 and a second insertion tube 4083 protruding from one end face of the first side mold 201. A first insertion hole 4082 and a second insertion hole 4084, respectively adapted to the first insertion tube 4081 and the second insertion tube 4083, are recessed on the corresponding end face of the second side mold 202. A first cooling pipe 4085 and a second cooling pipe 4086 are provided inside the first side mold 201. The two ends of the first cooling pipe 4085 are respectively connected to an inlet 401 and the first insertion tube 4081. The two ends of the second cooling pipe 4086 are respectively connected to an outlet 402 and the second insertion tube 4083. A third cooling pipe 4087 is provided inside the second side mold 202. The two ends of the third cooling pipe 4087 are respectively connected to the first insertion hole 4082 and the second insertion hole 4084.

[0032] When the first side mold 201 and the second side mold 202 are closed, the first insertion tube 4081 is inserted into the first insertion hole 4082, and the second insertion tube 4083 is inserted into the second insertion hole 4084, thereby forming a water flow path of inlet 401 - first cooling pipe 4085 - first insertion tube 4081 - first insertion hole 4082 - third cooling pipe 4087 - second insertion hole 4084 - second insertion tube 4083 - second cooling pipe 4086 - outlet 402.

The evaporator 406 is installed on the inner wall of the refrigeration water tank 405.

[0034] In a preferred embodiment, the pressure feeding assembly 30 includes a feed pipe 301 vertically disposed at the upper end of the upper mold 203. The upper mold 203 has a feed hole that is connected to and passes through the feed pipe 301. Above the feed pipe 301, a second cylinder 303 is mounted on the upper mold 203 via a bracket 302. A pressure piston is matched inside the feed pipe 301. The telescopic rod of the second cylinder 303 is vertically downward and fixedly connected to the pressure piston. The side wall of the feed pipe 301 has an injection port 304 communicating with the interior.

[0035] The molten material is injected from the injection port 304 into the feed pipe 301 and the die-casting space. Then, the pressure piston moves towards the lower mold 204 under the drive of the second cylinder 303, thereby pressing the material into the various gaps of the die-casting space.

[0036] In a preferred embodiment, the horizontal propulsion mechanism 206 includes a first cylinder 2061 horizontally mounted on the frame 10 and at least four first guide rods 2062 distributed around the first cylinder 2061 and slidably mounted on the frame 10.

[0037] In a preferred embodiment, a support assembly is provided on the outer side of both the first side mold 201 and the second side mold 202. The support assembly includes a first upright plate 2063 and a second upright plate 2064 fixedly mounted on the frame 10. The first upright plate 2063 and the second upright plate 2064 are spaced apart along the moving direction of the first side mold 201 and the second side mold 202.
