Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting mold technology, specifically to a cold-cast aluminum alloy wheel hub mold for a Kaba vehicle. Background Technology

[0002] As one of the most important safety components of a car, the wheel hub bears the pressure from the weight of the vehicle and its load, is subjected to dynamic torque during vehicle start-up and braking, and also withstands irregular alternating forces from different directions caused by dynamic loads from turning, uneven road surfaces, and impacts from road obstacles during driving. The product quality and reliability of the wheel hub not only affect the safety of the vehicle and its occupants and cargo, but also influence the vehicle's stability, handling, and comfort during driving. Furthermore, the wheel hub is an important part of the car's exterior appearance.

[0003] Due to their heavy loads, Kaba vehicles place higher demands on the load-bearing capacity of their wheels. Currently, Kaba wheels are mostly made of cast steel, pure low-pressure cast aluminum alloy, or forged aluminum alloy. Steel wheels are almost twice the weight of forged aluminum alloy wheels, resulting in high fuel consumption and reducing the vehicle's effective load capacity. Forged aluminum alloy wheels face obstacles to market entry due to the large investment in forging equipment and complex processing. Existing pure low-pressure cast aluminum alloy wheels also suffer from low material properties and insufficient lightweighting, which affects their market share. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a lightweight, cold-cast aluminum alloy wheel hub mold for Kaba vehicles.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a high-strength cold-casting rotary carbide aluminum alloy wheel hub mold, including an upper mold assembly, a lower mold assembly, and a side mold assembly, and also includes an upper mold wheel disk water-cooling ring. The upper mold wheel disk water-cooling ring is disposed at the bottom end of the upper mold assembly. The upper mold wheel disk water-cooling ring includes multiple sets of side-drilled pipe groups arranged along the circumferential direction. Each set of side-drilled pipe groups includes two side-drilled pipe sections. The adjacent ends of the two side-drilled pipe sections are connected. The beginning and end ends of the two side-drilled pipe sections are respectively connected to a water inlet pipe and a water outlet pipe.

[0007] Furthermore, the side-drilled pipe assembly consists of four groups.

[0008] Furthermore, it also includes a pair of side mold water-cooling arc blocks, which are disposed at the upper and lower ends of the side mold assembly. The side mold water-cooling arc blocks include four side molds, each side mold including two arc-shaped cooling inlet and outlet circuits, each arc-shaped cooling inlet and outlet circuit including two first drill pipes connected at one end, and the other ends of the two first drill pipes are respectively connected to the water inlet pipe and the water outlet pipe.

[0009] Furthermore, it also includes a lower mold water-cooling plate, which is disposed on the lower mold assembly. The lower mold water-cooling plate includes two semi-arc water channel loops. Each semi-arc water channel loop includes four sequentially connected second drill pipes. The beginning and end of each semi-arc water channel loop are respectively connected to the inlet pipe and the outlet pipe.

[0010] Furthermore, it also includes two semi-arc-shaped water cooling circuits for the lower mold. The two semi-arc-shaped water cooling circuits for the lower mold are arranged on the lower mold assembly. The two semi-arc-shaped water cooling circuits for the lower mold include two semi-arc-shaped water channels. Each semi-arc-shaped water channel includes five sequentially connected third drill pipes. The beginning and end of each semi-arc-shaped water channel are respectively connected to an inlet pipe joint and an outlet pipe joint.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The material properties of the wheel hub are improved by the strong cooling process structure design of each part of the mold. After the casting is spun, its material properties are further improved, and lightweighting is achieved, making it a preferred mold structure.

[0013] 2. The cold-casting mold for Kaba vehicles in this solution enables the production of aluminum alloy Kaba wheels that are lighter than steel Kaba wheels and traditional pure cast Kaba wheels, and more cost-effective than forged aluminum alloy Kaba wheels. This reduces vehicle weight under the springs, resulting in energy conservation and emission reduction, contributing to carbon peaking, and increasing the carrying capacity of Kaba vehicles.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] See appendix Figure 1 To be continued Figure 2 As shown, this embodiment provides a cold-cast aluminum alloy wheel hub mold 10 for a car, including an upper mold assembly 100, a lower mold assembly 300, and a side mold assembly 200. The upper mold assembly 100, the lower mold assembly 300, and the side mold assembly 200 together form a metal casting cavity.

[0038] See attached document Figure 1 Appendix Figure 2 and appendix Figure 3 and attached Figure 4 As shown, an upper mold wheel water-cooling ring 500 is provided at the bottom of the upper mold assembly 100. The upper mold wheel water-cooling ring 500 is used to cool the upper end of the cast product 400 in the strong cooling casting aluminum alloy wheel mold 10. Specifically, the upper mold wheel water-cooling ring 500 includes multiple sets of side-drilled pipe groups 501 arranged in the circumferential direction, for example, four sets of side-drilled pipe groups 501. Each set of side-drilled pipe groups 501 includes two side-drilled pipe sections 5011, with one end of each adjacent side-drilled pipe section 5011 connected. The beginning and end of the two side-drilled pipe sections 5011 are connected to an inlet pipe and an outlet pipe, respectively.

[0039] During use, external cooling water enters the side-drilled pipe assembly 501 through the inlet pipe, flows through the side-drilled pipe 5011, and flows out through the outlet pipe. During the flow of the cooling water in the side-drilled pipe 5011, it exchanges heat with the casting product 400 located in the strong cold casting aluminum alloy wheel hub mold 10, cools the casting product 400, and improves the material properties of the casting product 400 (wheel hub).

[0040] See attached document Figure 1 Appendix Figure 2 and appendix Figure 5 and attached Figure 6 As shown, the upper and lower ends of the side mold assembly 200 are respectively provided with side mold water cooling arc blocks 600. The side mold water cooling arc blocks 600 are used to cool the sides of the casting product 400 in the strong cold casting aluminum alloy wheel hub mold 10. Specifically, the side mold water cooling arc blocks 600 include four side molds 601. Each side mold 601 includes two arc-shaped cooling inlet and outlet circuits. Each arc-shaped cooling inlet and outlet circuit includes two first drill pipes 6011 connected at one end. The other ends of the two first drill pipes 6011 are connected to the water inlet pipe and the water outlet pipe, respectively.

[0041] Similarly, external cooling water enters each arc-shaped cooling inlet and outlet circuit through the inlet pipe, flows through the drill pipe, and flows out through the outlet pipe. During the flow of the cooling water in the first drill pipe 6011, it exchanges heat with the casting product 400 located in the strong cold casting aluminum alloy wheel hub mold 10, thereby cooling the casting product 400.

[0042] See attached document Figure 1 Appendix Figure 2 and appendix Figure 7 and attached Figure 8 As shown, a lower mold assembly 300 is provided with a lower mold water-cooling plate 700, which is used to cool the lower end of the casting product 400 in the strong cooling casting aluminum alloy wheel hub mold 10. Specifically, the lower mold water-cooling plate 700 includes two semi-arc-shaped water channel loops 701. Each semi-arc-shaped water channel loop 701 includes four sequentially connected second drill pipes 7011. The first and last ends of each semi-arc-shaped water channel loop 701 are connected to the inlet pipe 900 and the outlet pipe 110, respectively.

[0043] Similarly, external cooling water enters the semi-arc-shaped water channel circuit 701 through the inlet pipe 900, flows through the second drill pipe 7011, and flows out through the outlet pipe 110. During the flow of the cooling water in the second drill pipe 7011, it exchanges heat with the casting product 400 located in the strong cold casting aluminum alloy wheel hub mold 10, thereby cooling the casting product 400.

[0044] See attached document Figure 1 Appendix Figure 2 and appendix Figure 9 and attached Figure 10 As shown, the lower mold assembly 300 is also equipped with a lower mold two-half-arc water cooling circuit 800, which is used to cool the lower end of the casting product 400 in the strong cooling casting aluminum alloy wheel hub mold 10. Specifically, the lower mold two-half-arc water cooling circuit 800 includes two semi-arc water channels 701, each semi-arc water channel 701 including five third drill pipes 7011 connected in sequence, and the first and last ends of each semi-arc water channel 701 are respectively connected to the inlet pipe joint and the outlet pipe joint.

[0045] Similarly, external cooling water enters the semi-circular water channel 701 through the inlet pipe joint, flows through the third drill pipe 7011, and flows out through the outlet pipe joint. During the flow of the cooling water in the third drill pipe 7011, it exchanges heat with the casting product 400 located in the strong cold casting aluminum alloy wheel hub mold 10, thereby cooling the casting product 400.
