Description

Technical Field

[0001] This invention relates to the field of aluminum alloy wheel hub processing technology, and more specifically to a multi-size integrated casting device and method for aluminum alloy wheel hubs. Background Technology

[0002] In the manufacturing process of aluminum alloy wheels, the casting stage is a crucial step, directly determining the forming quality and production efficiency of the wheel. Traditional aluminum alloy wheel casting typically uses molds of fixed dimensions for production. This mold structure has certain advantages when producing wheels of a single size, but with the diversification and personalization of market demands, the limitations of single-size molds are becoming increasingly apparent.

[0003] First, different customers have varying size requirements for aluminum alloy wheels, ranging from the common 15-inch to 22-inch, and even larger sizes. When using fixed-size molds for production, companies need to equip each size with a separate mold, which not only increases the manufacturing cost of the molds but also complicates their storage and management. Frequent mold changes when producing different sizes consume significant time and manpower, severely impacting production efficiency and making it difficult to meet rapidly changing market demands.

[0004] Secondly, during the new product development and trial production stages, companies often need to conduct multiple trials and improvements on wheel hubs of different sizes. The use of fixed-size molds limits the flexibility of testing; each adjustment to the wheel hub size requires redesigning and manufacturing the mold, which not only prolongs the development cycle but also increases development costs, hindering the company's innovation and development.

[0005] Furthermore, with intensifying market competition, aluminum alloy wheel manufacturers face the dual pressures of reducing costs, improving production efficiency, and enhancing product quality. Traditional fixed-size molds cannot effectively meet these requirements; therefore, developing a mold system capable of adapting to the production of multi-size wheels is particularly urgent.

[0006] In summary, the use of fixed-size molds in the current aluminum alloy wheel casting industry presents numerous problems, such as high mold costs, cumbersome replacement, low production efficiency, and hindering new product development. These issues severely restrict the market competitiveness and sustainable development capabilities of aluminum alloy wheel manufacturers. Therefore, there is an urgent need for a detachable, combinable mold with different size structures to achieve integrated casting of multi-size wheels, improve production efficiency, reduce costs, meet diverse market demands, and promote technological progress and development in the aluminum alloy wheel industry.

[0033] See appendix Figure 1 To be continued Figure 2 This invention discloses a multi-size integrated casting device for aluminum alloy wheel hubs, comprising: Lower mold base 1; Lower mold 2 is detachably connected to the center of the surface of lower mold base 1; There are multiple segmented side molds 3, which are arranged around the lower mold 2 on the surface of the lower mold base 1. The segmented side molds 3 are detachably connected to the surface of the lower mold base 1, and can slide with the surface of the lower mold base 1 after connection. Multiple segmented side molds 3 achieve circumferential mold closing and opening control through radial movement. Angle mold 4 is detachably connected to the surface of the lower mold base 1 and is located between two adjacent segmented side molds 3, used to achieve mold closing and positioning of the segmented side molds 3; The upper mold 5 is arranged above the lower mold 2 and is used to form a cavity for processing the wheel hub 6 with the lower mold 2 and multiple segmented side molds 3.

[0034] See appendix Figure 3 and attached Figure 4 The bottom of the split-side mold 3 has a first slider 31, and the top surface of the lower mold base 1 has a first groove 11 that cooperates with the first slider 31. The end of the first groove 11 away from the lower mold 2 has a first insertion port 12. The first slider 31 enters the first groove 11 from the first insertion port 12 and slides with the first groove 11.

[0035] The first slider 31 at the bottom of the segmented side mold 3 cooperates with the first sliding groove 11 on the top surface of the lower mold base 1, so that the segmented side mold 3 can be easily slidably installed onto the surface of the lower mold base 1, thereby improving the installation efficiency and accuracy of the mold.

[0036] To further optimize the above technical solution, a hydraulic cylinder 7 for driving the movement of the segmented side mold 3 is also included. The cylinder body of the hydraulic cylinder 7 is mounted and fixed on the lower mold base 1.

[0044] To further optimize the above technical solution, the support frame 8 is threaded with two positioning screws 84. The two positioning screws 84 are symmetrically arranged on both sides of the adjusting screw 81. The end of the positioning screw 84 facing the side wall of the corner mold 4 has a tightening head 85, and the other end of the positioning screw 84 has a positioning handwheel 86.

[0045] The positioning screw 84 provides dual positioning protection for the corner mold 4, further enhancing the stability of the corner mold 4, making the mold more reliable during the casting process, and helping to improve the dimensional accuracy and surface quality of the wheel hub.

[0046] To further optimize the above technical solution, when the adjusting screw 81 is in the retracted state, the second slider 41 can be inserted into the second insertion port 14, and then the adjusting screw 81 is rotated so that the connecting plate 82 abuts against the outer wall of the corner mold 4 and is fastened by bolts.

[0047] When the adjusting screw 81 is in the retracted state, the second slider 41 can be smoothly inserted into the second insertion port 14. Then, by rotating the adjusting screw 81, the corner mold 4 can be quickly positioned and fastened, which simplifies the installation process of the corner mold 4 and improves the assembly efficiency of the mold.

[0048] To further optimize the above technical solution, the lower mold and the lower mold base are fastened together by bolts.
