Description

Technical Field

[0001] This utility model relates to the technical field of automobile wheel hub processing, specifically a temperature control device for wheel hub forming molds. Background Technology

[0002] The wheel hub is the part of the wheel where the axle is mounted. It is commonly referred to as the "wheel rim" or "steel rim". It consists of spokes and a rim. Currently, with the mass production of automobiles, the production of automobile wheel hubs is also increasing. Wheel hubs have the advantages of being aesthetically pleasing, providing good support at high speeds, excellent handling, and short braking distances.

[0003] However, with repeated use, the temperature of existing wheel hub casting molds increases. If the mold is not cooled in time, it will not only affect its service life but also the quality of the castings.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] The hydraulic telescopic rod in this utility model is a common hydraulic device in the prior art, and this application will not elaborate on its model or internal structure.

[0028] like Figure 1-4As shown, this utility model provides a technical solution: a temperature control device for a wheel hub forming mold, including a base plate 1, a bottom mold 2 fixedly installed on the upper surface of the base plate 1, a side mold 3 slidably connected to the upper surface of the base plate 1, a tie rod 22 fixedly connected to the outer surface of the side mold 3, a temperature display 23 provided on the outer surface of the side mold 3, and a temperature acquisition, signal conditioning and data processing system provided inside the display. The sensor converts temperature changes into electrical signals of resistance / voltage / potential difference, the signal conditioning amplifier enhances the signal strength, the filter eliminates interference, the converter quantizes the data, and the microprocessor runs algorithms, such as lookup table method and polynomial fitting, to calculate the actual temperature value. The bottom mold 2 is used to cast the surface of the wheel hub, and the side mold 3 is used to cast the edge of the wheel hub. The mold material of the side mold 3 is steel, which has high strength and wear resistance.

[0029] A clamping plate 15 is fixedly connected to the upper surface of the base plate 1, and a clamping groove 16 is opened on the bottom surface of the side mold 3. The outer surface of the clamping plate 15 is slidably connected to the inner wall of the clamping groove 16. When demolding, by pulling the side mold 3, the clamping plate 15 will slide inside the clamping groove 16, and the four side molds 3 can be separated from the casting.

[0030] A blocking plate 17 is fixedly connected to the upper surface of the base plate 1. The outer surface of the blocking plate 17 is fixedly connected to one end of the clamping plate 15. Two clamping plates 15 are connected to one blocking plate 17. The blocking plate 17 is set to prevent the side mold 3 from detaching from the clamping plate 15 when it moves. The side mold 3 is made of steel. When the molding liquid is poured into the closed space, the side mold 3 will not move automatically because it has a certain weight.

[0031] The side mold 3 is internally fixedly connected with a guide pipe 4, which is composed of bent pipes and straight pipes. The bent pipes and straight pipes are interconnected. The four side molds 3 are all equipped with guide pipes 4. There are a total of nine bent pipes. Three bent pipes are placed on one horizontal plane, and there are a total of three horizontal planes, which increases the cooling rate of the side mold 3. The guide pipe 4 and the spiral pipe 7 are made of the same material as the side mold 3, so they will not be damaged by high temperature.

[0032] One end of the guide pipe 4 is fixedly connected to the inlet 18, and the other end of the guide pipe 4 is fixedly connected to the outlet 19. High-pressure cold water is injected into the inlet 18 and passes through the guide pipe 4 inside the side mold 3 to cool the side mold 3. The water finally flows out from the outlet 19. The outer surface of the base plate 1 is fixedly connected to the side plate 5. The top mold 6 is set on the top of the base plate 1. There are four side molds 3 in total. The side molds 3 are symmetrically distributed with the central axis of the base mold 2 as the center. The four side molds 3 form a circle, so that the top mold 6, the base mold 2 and the side molds 3 form a closed space, which is the shape of the wheel hub.

[0033] The top mold 6 is internally fixedly connected to a spiral tube 7. One end of the spiral tube 7 is fixedly connected to a threaded outlet 20, and the other end of the spiral tube 7 is fixedly connected to a threaded inlet 21. The outer surfaces of the threaded outlet 20 and the threaded inlet 21 are both provided with threads to facilitate connection with pipes. The spiral tube 7 can increase the contact area with the top mold 6 and improve the cooling rate of the top mold 6. The outer surface of the base plate 1 is fixedly connected to a triangular plate 8.

[0034] A hydraulic telescopic rod 9 is fixedly installed on the bottom surface of the side plate 5. The hydraulic telescopic rod 9 has internal structures such as cylinder, piston, piston rod and seals. The working principle of the hydraulic telescopic rod 9 is based on Pascal's law, that is, the pressure applied to a closed liquid will be evenly transmitted to all parts of the liquid. Through this force transmission method, the hydraulic telescopic rod 9 can realize the support and motion control of external loads.

[0035] A circular plate 10 is fixedly connected to the bottom end of the hydraulic telescopic rod 9. A support rod 11 is fixedly connected to the bottom end of the circular plate 10. A cover plate 12 is fixedly connected to the bottom end of the support rod 11. The bottom surface of the cover plate 12 is fixedly connected to the upper surface of the top mold 6. The outer surface of the cover plate 12 is slidably connected to the inner wall of the side mold 3. A feed inlet 13 is provided on the upper surface of the cover plate 12. A vent hole 14 is provided on the outer surface of the cover plate 12. The vent hole 14 helps to avoid product defects caused by gas residue, such as air holes, voids and loose structure.

[0036] Working principle: During use, the top mold 6 is lowered by adjusting the hydraulic telescopic rod 9, so that the top mold 6, bottom mold 2 and side mold 3 form a sealed space. Molding liquid is injected into the space through the feed port 13 to form the required wheel hub model. After the casting is completed, when demolding, the hydraulic telescopic rod 9 is activated, which drives the top mold 6 to move upward. Then, the side mold 3 is pulled by the pull rod 22. The clamping plate 15 will slide inside the clamping groove 16, which can detach the four side molds 3 from the casting, thus facilitating the demolding of the wheel hub. After demolding, when cooling the mold, cold water is injected into the water inlet 18, which passes through the guide pipe 4 inside the side mold 3 to cool the side mold 3. Then, cold water enters from the threaded inlet 21 and flows through the spiral pipe 7 to cool the top mold 6. The temperature display 23 can display the temperature of the side mold 3, which is convenient for controlling the temperature of the mold.
