Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting, and in particular to an aluminum-steel wheel hub extrusion casting mold with thermal fatigue resistance. Background Technology

[0002] The wheel hub is the part at the center of the wheel where the axle is mounted. It is also commonly referred to as the wheel rim or steel rim. The wheel hub is an important component of automobile parts. Car wheel hubs are usually die-cast using molds, a simple and quick process.

[0003] Existing automotive wheel hubs are prone to thermal fatigue due to uneven heating during production. Thermal fatigue can cause cracks on the wheel hub surface, reducing its performance and aesthetics, turning it into a defective product, and thus reducing production efficiency.

[0004] Therefore, we need to design an aluminum-steel wheel hub extrusion casting mold that is resistant to thermal fatigue. Utility Model Content

[0005] To overcome the problem of uneven heating during the production of automobile wheel hubs, which can lead to thermal fatigue and result in defective products, thus reducing production efficiency, this utility model provides an aluminum-steel wheel hub extrusion casting mold with resistance to thermal fatigue.

[0006] The technical implementation scheme of this utility model is as follows: an aluminum-steel wheel hub extrusion casting mold with thermal fatigue resistance, including a bracket, electric push rods, side molds, cylinders, upper molds and lower molds. Electric push rods are installed on both sides of the bracket, and side molds are connected to the sides of the two electric push rods that are close to each other. A cylinder is installed on the top of the bracket, and the upper mold is connected to the output shaft of the cylinder. After the two side molds are fitted together, the upper mold and the lower mold can be completely fitted together.

[0007] More preferably, it also includes an air vent pipe. Each side mold has a fixing block installed on both the front and back sides, and an air vent pipe is installed on the fixing block. The air outlet of the air vent pipe faces the side mold, and an air inlet pipe is connected to the side of the air vent pipe away from the side mold. There are four air vent pipes, which can cover the side mold and make heat dissipation more even.

[0008] More preferably, it also includes a vibration motor, with the vibration motor mounted on the top of the side mold, which can separate the mold that is attached to the side mold.

[0009] More preferably, it also includes sliding rods and push plates, with sliding rods slidably provided on both sides of the middle part of the bracket, and push plates installed on the side of the two sliding rods that are close to each other.

[0010] More preferably, it also includes a spring, with the spring wound around the sliding rod and the two ends of the spring connected to the bracket and the sliding rod respectively.

[0011] More preferably, it also includes a handle, with a handle installed at the end of the sliding rod away from the push plate to facilitate sliding the sliding rod.

[0012] Even more preferably, the push plate is made of silicone to prevent scratching the wheel hub.

[0013] More preferably, there are multiple heat-conducting plates on the outer wall of the side mold, through which the heat inside the side mold is dissipated.

[0014] Compared with the prior art, the present invention has the following advantages: The beneficial effects of the present invention are: 1. By setting an air outlet pipe, the continuous output of cold air from the air outlet pipe will cause the temperature of the two side molds to drop evenly. After the temperature stabilizes, the cast wheel hub will not have cracks, and the production efficiency will also be improved.

[0015] 2. By turning on the vibration motor, the continuous operation of the vibration motor will cause the hub inside the side mold to separate from the inner wall of the side mold. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] An aluminum-steel wheel hub extrusion casting mold with thermal fatigue resistance, such as... Figures 1-3As shown, the device includes a bracket 1, electric push rods 2, side molds 3, cylinders 4, upper molds 5, lower molds 6, air outlet pipes 7, vibration motors 8, sliding rods 9, push plates 10, springs 11, and handles 12. Electric push rods 2 are mounted on both sides of the bracket 1, and the side molds 3 are connected to adjacent sides of the two electric push rods 2. The electric push rods 2 can tightly fit the two side molds 3 together. Multiple heat-conducting plates are located on the outer wall of each side mold 3, allowing heat to dissipate from within the side mold 3. The cylinder 4 is mounted on the top of the bracket 1, and the upper mold 5 is connected to the output shaft of the cylinder 4. When the two side molds 3 are fitted together, the upper mold 5 and the lower mold 6 can be completely fitted together. Fixing blocks are installed on both the front and rear sides of each side mold 3, and air outlet pipes 7 are mounted on the fixing blocks. The air outlet of the air outlet pipe 7 faces the side mold 3, and the air outlet of the air outlet pipe 7... The outlet continuously blows air onto the side mold 3, which can stably maintain cooling. The side of the air outlet 7 away from the side mold 3 is connected to the air inlet pipe. There are four air outlet pipes 7, which can cover the side mold 3 and make heat dissipation more even. The vibration motor 8 is installed on the top of the side mold 3. The vibration motor 8 can separate the mold attached to the side mold 3. The middle of the bracket 1 has sliding rods 9 on both sides. The push plate 10 is installed on the side of the two sliding rods 9 that are close to each other. The push plate 10 is made of silicone to prevent scratching the wheel hub. The spring 11 is wound around the sliding rod 9. The two ends of the spring 11 are respectively connected to the bracket 1 and the sliding rod 9. The spring 11 can reset the pushed sliding rod 9 and the push plate 10. The handle 12 is installed on the end of the sliding rod 9 away from the push plate 10 to facilitate sliding the sliding rod 9.

[0023] When this device is needed, first activate the two electric push rods 2. Activating the electric push rods 2 will move the two side molds 3 towards each other. Simultaneously, activate the cylinder 4. Activating the cylinder 4 will push the upper mold 5 downwards. After the two side molds 3 and the upper mold 5 have moved to their designated positions, the molds will be completely aligned. Then, molten aluminum is poured into the molds through the inlet of the upper mold 5. Next, cold air is introduced into the outlet pipe 7 through the inlet pipe. The cold air in the outlet pipe 7 will be sprayed onto the outer wall of the side molds 3 through the outlet. Simultaneously, the heat inside the side molds 3 will be dissipated through the heat-conducting plates. After the temperature has cooled down, activate the vibration motor 8. The continuous operation of the vibration motor 8 causes the hub inside the side mold 3 to separate from the inner wall of the side mold 3. Then, the two electric push rods 2 are activated again, and the output shafts of the two electric push rods 2 retract, causing the side mold 3 to completely separate from the hub. Then, the output shaft of the cylinder 4 is retracted, causing the upper mold 5 to separate from the hub. When the hub is stuck to the upper mold 5, the handle 12 is pushed towards the upper mold 5, causing the spring 11 to stretch. At the same time, the push plate 10 will continuously push the hub, causing the push plate 10 to separate from the upper mold 5. Then, the handle 12 is released, and the sliding rod 9 and the push plate 10 will return to their original positions under the action of the spring 11.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
