Description

Technical Field

[0001] This utility model relates to an aluminum alloy wheel hub casting mold, belonging to the field of wheel hub manufacturing technology. Background Technology

[0002] Aluminum alloy wheels are wheels made of aluminum alloy, offering numerous advantages over traditional steel wheels. Their main characteristics include: high strength and lightweight: Aluminum alloy wheels are lighter yet stronger than steel wheels. This lightweight design reduces drag during start-up and acceleration, resulting in better fuel economy. Good corrosion resistance: Aluminum alloys have excellent corrosion resistance, resisting erosion from various harsh environments and extending the wheel's lifespan. Excellent heat dissipation: Aluminum alloy has a thermal conductivity coefficient three times that of steel, providing excellent heat dissipation. Even during long-distance high-speed driving, it keeps tires at an appropriate temperature, preventing brake overheating and increasing the lifespan of tires and the braking system.

[0022] Please see Figure 1-6As shown, an aluminum alloy wheel hub casting mold includes a mounting base plate 1. Several support rods 2 are fixedly connected to the top of the mounting base plate 1. A lower mold positioning seat 3 is fixedly mounted on the top of the support rods 2. A semi-circular wheel hub lower mold 4 is symmetrically arranged on the top of the lower mold positioning seat 3. Displacement components 5 for moving the semi-circular wheel hub lower mold 4 are provided on both sides of the top of the mounting base plate 1. A connecting rectangular rod 6 is fixedly mounted on the top of the mounting base plate 1. A vertical lifting component 7 is provided on the connecting rectangular rod 6, and a vertical lifting component 7 is mounted on the vertical lifting component 7. There is an L-shaped support frame 8, and an upper mold connecting plate 9 is fixedly connected to the outer side wall of the L-shaped support frame 8. A hub casting upper mold 10 is fixed to the bottom of one end of the upper mold connecting plate 9. A pouring hole is opened on the hub casting upper mold 10. A filter assembly 11 for filtering the pouring liquid is connected to the top of the hub casting upper mold 10. A positioning assembly 12 for positioning the filter assembly 11 is installed on the L-shaped support frame 8. The filter assembly 11 can be positioned by the positioning assembly 12 to prevent the filter assembly 11 from being displaced.

[0023] Rectangular grooves are provided on both sides of the top of the lower mold positioning seat 3. A sliding block 13 is slidably engaged in the rectangular groove. The bottom of the sliding block 13 is fixedly connected to the bottom of the semi-circular hub lower mold 4. The displacement component 5 includes a support seat 501 fixedly installed on both sides of the top of the mounting base plate 1. A displacement telescopic rod 502 is connected to the outer wall of the support seat 501. One end of the displacement telescopic rod 502 is fixed to the outer wall of the semi-circular hub lower mold 4. When the displacement telescopic rod 502 moves the semi-circular hub lower mold 4, it can move the sliding block 13 in the rectangular groove.

[0024] The vertical lifting assembly 7 includes a vertical telescopic rod 701, which is fixedly connected to the top of the connecting rectangular rod 6. A rectangular through hole is provided on the connecting rectangular rod 6, and a vertical lifting block 702 is slidably engaged in the rectangular through hole. One end of the vertical telescopic rod 701 is fixed to the top of the vertical lifting block 702. An L-shaped support frame 8 is fixedly connected to the vertical lifting block 702. Through the vertical telescopic rod 701, the vertical lifting block 702 and the L-shaped support frame 8 can be displaced, thus driving the upper mold 10 of the wheel hub casting to move.

[0025] The filter assembly 11 includes a plug-in tube 1101, which is fixed to the top of the upper mold 10 for wheel hub casting. The plug-in tube 1101 corresponds to the pouring hole. A filter tube 1102 is inserted into the plug-in tube 1101. A filter screen 1103 is fixedly installed on the inner side wall of the filter tube 1102. A positioning ring 1104 is fixedly installed on the outer side wall of the filter tube 1102. The filter tube 1102 is inserted into the plug-in tube 1101. When the external force is released, the user can pull the filter tube 1102 upward to remove it.

[0026] The positioning assembly 12 includes a positioning telescopic rod 1201 fixed on the top of the L-shaped support frame 8. A connecting plate 1202 is fixed on one end of the positioning telescopic rod 1201. A pressure ring 1203 is fixedly connected to the bottom of the connecting plate 1202. The pressure ring 1203 is sleeved on the outside of the filter cylinder 1102 and is pressed against the positioning ring 1104. When the positioning telescopic rod 1201 rises, it can drive the connecting plate 1202 and the pressure ring 1203 to rise. After the pressure ring 1203 rises, it can release the restriction on the positioning ring 1104 and the filter cylinder 1102.

[0027] In use, during wheel hub casting, the user can pour the molten casting liquid into the filter cylinder 1102. The casting liquid can then be filtered through the filter screen 1103, which effectively removes impurities from the casting liquid, laying a solid foundation for casting high-quality aluminum alloy wheels. After the cast wheel hub is formed in the semi-circular lower wheel hub mold 4 and the upper wheel hub casting mold 10, the user can activate the upper and lower telescopic rods 701 to drive the upper and lower lifting blocks 702 to rise, thereby driving the L-shaped support frame 8, the upper mold connecting plate 9, and the upper wheel hub casting mold 10 to rise. Afterward, the user can activate the displacement telescopic rod 502 to move the semi-circular lower wheel hub mold 4 to one side. After the mold is opened, the user can take out the cast wheel hub.
