Description

Technical Field

[0001] This utility model belongs to the field of wheel hub casting technology, specifically, it relates to a multi-station wheel hub forming mold. Background Technology

[0002] A wheel hub is a cylindrical metal component mounted on an axle that supports the tire. It is also called a wheel rim, steel rim, wheel, or tire wheel. Wheel hubs come in many varieties depending on their diameter, width, forming method, and materials. In the past, passenger car wheel hub bearings were most commonly used in pairs of single-row tapered roller or ball bearings. With technological advancements, passenger cars now widely use passenger car wheel hub units.

[0003] Chinese utility model patent CN219561374U discloses a wheel hub forming mold. Through a forming mechanism and an injection extrusion mechanism, the device allows the aluminum alloy solution for wheel hub forming to be added from the inlet between the upper and lower molds. Pressure is applied to the aluminum alloy solution inside the upper and lower molds by a pressure plate, allowing the solution to fill the gaps inside the molds, forming the shape of a wheel hub. Finally, it crystallizes and solidifies, producing a certain amount of plastic deformation during the crystallization process. This prevents the formation of air pockets inside the wheel hub, resulting in a denser structure. Compared to conventional methods of producing wheel hubs by forging aluminum parts, which involve numerous production steps and high costs, this forming mold can reduce the production steps, lower manufacturing costs, and facilitate wheel hub production.

[0004] Although the mold facilitates the production of wheel hubs, it only allows for molding at a single station, meaning that only one wheel hub can be molded at a time. When higher production efficiency is required, multiple molds and multiple lifting components must be prepared, which increases costs. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-station wheel hub forming mold that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: The multi-station wheel hub forming mold includes a bottom support. An assembly vertical post is detachably connected to the upper center of the bottom support. Multiple upper molds that can slide up and down are installed on the assembly vertical post. An injection pipe is provided at the upper end of the upper mold. Multiple lower molds are embedded in the upper end of the bottom support. Each upper mold is perpendicular to the lower mold. The lower mold is formed by two arc-shaped parts inserted together. After the upper mold descends and closes with the lower mold, aluminum alloy liquid is injected between the upper mold and the lower mold through the injection pipe.

[0007] Furthermore, a lifting assembly is installed above the assembled vertical pile. The lifting assembly drives the upper mold to move upward or downward, so that the upper mold and the lower mold can close together.

[0008] Furthermore, the lifting assembly includes a pressing cylinder, a drive connecting block, a sliding groove, and a sliding plate. The upper end of the assembly vertical pile is detachably connected to the pressing cylinder, and the telescopic end of the pressing cylinder is inserted into the interior of the assembly vertical pile. The outer wall of the assembly vertical pile is provided with multiple sliding grooves. The outer wall of each upper mold is detachably connected to a sliding plate inserted into the interior of the assembly vertical pile. The telescopic end of the pressing cylinder is detachably connected to the drive connecting block, and the insertion slot is inserted into the drive connecting block.

[0009] Furthermore, each upper mold has a first ring slidably connected to its outer wall, and a handle is detachably connected to one side of the outer wall of the first ring. An adjustment component is installed on the first ring, which can lock or unlock the upper mold and the drive connection block.

[0010] Furthermore, the upper end of the drive connecting block is provided with multiple insertion slots, the upper end of each insertion slot penetrates through the drive connecting block, and the end of the sliding plate is inserted into the interior of the insertion slot.

[0011] Furthermore, the adjustment assembly includes an insertion plate, a second collar, a limiting post, a second limiting hole, and a first limiting hole. The end of the insertion plate that is inserted into the assembly vertical pile is fixedly connected to the second collar. The front and rear outer walls of the two sides of the second collar are fixedly connected to the limiting posts. The drive connecting block is provided with a second limiting hole at the position on both sides of each second limiting hole. The assembly vertical pile is provided with a first limiting hole at the position on both sides of each sliding groove near the top.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. In this utility model, multiple upper molds move downwards and close with the lower mold, and aluminum alloy liquid is added from the injection pipe between the upper mold and the lower mold, thereby enabling the one-time molding of multiple aluminum alloy wheel hubs, resulting in higher production efficiency and the molding of multiple aluminum alloy wheel hubs in a single time.

[0013] 2. In this utility model, by extending and shortening the downward pressure cylinder, each upper mold can be moved upward or downward, thereby achieving the simultaneous lifting and lowering of multiple upper molds through one downward pressure cylinder, which saves energy and reduces production and usage costs.

[0014] 3. In this utility model, by holding the handle, the first ring and the insertion plate can slide on the outer wall of the sliding plate, thereby realizing the locking and unlocking between the upper mold and the drive connecting block. In this way, an appropriate number of upper molds can be selected to rise and fall simultaneously according to actual needs, making the application range wider.

[0015] 4. In this utility model, when the upper mold is unlocked from the drive connecting block, the drive connecting block moves downward so that the sliding plate on the unlocked upper mold disengages from the inside of the insertion slot, thereby preventing the unlocked upper mold from rising and falling with the drive connecting block.

[0016] 5. In this utility model, by holding the handle, the sliding plate, the insertion plate, and the second ring move laterally, so that when the limiting pin is inserted into the second limiting hole and disengaged from the first limiting hole, the upper mold moves up and down with the extension and retraction of the pressing cylinder. When the limiting pin is inserted into the first limiting hole and disengaged from the second limiting hole, the upper mold is fixed to the assembly vertical pile and will not move up and down with the extension and retraction of the pressing cylinder.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] Example 1: Reference Figure 1 As shown, this is a schematic diagram of the multi-station wheel hub forming mold structure in this embodiment. The multi-station wheel hub forming mold in this embodiment includes a bottom support 100. An assembly vertical post 101 is detachably connected to the upper center of the bottom support 100. Multiple upper molds 200 that can slide up and down are installed on the assembly vertical post 101. An injection pipe 202 is provided at the upper end of the upper mold 200. Multiple lower molds 201 are embedded in the upper end of the bottom support 100. Each upper mold 200 is perpendicular to the lower mold 201. The lower mold 201 is formed by two arc-shaped parts inserted together. In this embodiment, by moving the multiple upper molds 200 downwards to close with the lower molds 201, aluminum alloy liquid is added from the injection pipe 202 between the upper molds 200 and the lower molds 201, thereby realizing the one-time forming of multiple aluminum alloy wheel hubs, which makes the production efficiency higher and allows multiple aluminum alloy wheel hubs to be formed in a single time.

[0022] like Figure 2 As shown, this is a cross-sectional view of the multi-station wheel hub forming mold in this embodiment. The upper end of the assembly vertical pile 101 is detachably connected to a pressing cylinder 300. The telescopic end of the pressing cylinder 300 is inserted into the interior of the assembly vertical pile 101. The outer wall of the assembly vertical pile 101 is provided with multiple sliding grooves 102. The outer wall of each upper mold 200 is detachably connected to a sliding plate 203 inserted into the interior of the assembly vertical pile 101. The telescopic end of the pressing cylinder 300 is detachably connected to a drive connecting block 301. The insertion slot 302 is inserted into the drive connecting block 301. In this embodiment, by extending and shortening the pressing cylinder 300, each upper mold 200 can be moved upward or downward. Thus, multiple upper molds 200 can be simultaneously raised and lowered by one pressing cylinder 300, which saves energy and reduces production and usage costs.

[0023] It is worth noting that the aforementioned pressing cylinder 300, drive connecting block 301, sliding groove 102 and sliding plate 203 are lifting components in this embodiment. The lifting components include, but are not limited to, pressing cylinder 300, drive connecting block 301, sliding groove 102 and sliding plate 203. Any component that can make each upper mold 200 rise and fall can be applied to this embodiment.

[0024] like Figure 3 As shown, this is the embodiment of the present invention. Figure 1The enlarged structural diagram at point A shows that the outer wall of each upper mold 200 is slidably connected to a first ring 204, and the outer wall of each first ring 204 is fixedly connected to an insertion plate 205 inserted into the assembly vertical post 101. A handle 206 is detachably connected to one side of the outer wall of the first ring 204. In this embodiment, by holding the handle 206, the first ring 204 and the insertion plate 205 can slide on the outer wall of the sliding plate 203, thereby enabling locking and unlocking between the upper mold 200 and the drive connecting block 301. This allows for the simultaneous lifting and lowering of an appropriate number of upper molds 200 according to actual needs, making the application range more extensive.

[0025] like Figure 4 As shown, this is a schematic diagram of the adjustment component structure in this embodiment. The upper end of the drive connecting block 301 is provided with multiple insertion slots 302. The upper end of each insertion slot 302 passes through the drive connecting block 301. The end of the sliding plate 203 is inserted into the interior of the insertion slot 302. In this embodiment, when the upper mold 200 is unlocked from the drive connecting block 301, the drive connecting block 301 moves downward, causing the sliding plate 203 on the unlocked upper mold 200 to disengage from the interior of the insertion slot 302, thereby preventing the unlocked upper mold 200 from rising and falling with the drive connecting block 301.

[0026] like Figure 4 As shown, the end of the insertion plate 205 inserted into the assembly vertical post 101 is fixedly connected to a second collar 207. Limiting pins 208 are fixedly connected to the front and rear outer walls on both sides of the second collar 207. The drive connecting block 301 is provided with second limiting holes 303 on both sides of each second limiting hole 303. The assembly vertical post 101 is provided with first limiting holes 103 on both sides of each sliding groove 102 near the top. In this embodiment, by holding the grip handle 206, the sliding plate 203, the insertion plate 205 and the second collar 207 move laterally. When the limiting pins 208 are inserted into the second limiting holes 303 and disengaged from the first limiting holes 103, the upper mold 200 moves up and down with the extension and retraction of the lower cylinder 300. When the limiting pins 208 are inserted into the first limiting holes 103 and disengaged from the second limiting holes 303, the upper mold 200 is fixed to the assembly vertical post 101 and will not move up and down with the extension and retraction of the lower cylinder 300.

[0027] It is worth noting that the aforementioned insertion plate 205, second collar 207, limiting post 208, second limiting hole 303, and first limiting hole 103 are adjustment components in this embodiment. The adjustment components include, but are not limited to, insertion plate 205, second collar 207, limiting post 208, second limiting hole 303, and first limiting hole 103. Any component that can lock or unlock the upper mold 200 and the drive connecting block 301 can be applied to this embodiment.
