Wheel hub mold anti-dislocation structure

Abstract

This utility model discloses a wheel hub mold anti-misalignment structure, belonging to the technical field of wheel hub molds. It includes a wheel hub side module, inter-block limiting blocks, a bottom fixing plate, and through holes. The wheel hub side module has a right-angle notch-shaped side notch, and an inter-block limiting block is embedded between adjacent side notches. This limiting block can prevent the wheel hub side module from moving forward but does not affect its backward movement. A fixing plate with through holes is provided at the bottom of the limiting block and is fixed to the ground with bolts. This utility model, by setting a side notch on the wheel hub side module and fixing a bottom fixing plate to the ground with bolts, and setting an upright inter-block limiting block on the bottom fixing plate, can forcibly limit the forward movement of the wheel hub side module, improve the control safety of the wheel hub mold, and prevent the wheel hub side mold from moving too far forward, causing the side mold surface of the adjacent and relatively lagging wheel hub side module to collide with the relatively advanced wheel hub side module and be damaged.

Description

Technical Field

[0001] This utility model belongs to the technical field of wheel hub molds, and particularly relates to a wheel hub mold anti-misalignment structure. Background Technology

[0002] Wheel hub molds generally consist of three parts: top module, side module, and bottom module. The side module is usually divided into four pieces, each driven by a drive mechanism. Moving forward, they combine to form a circle, while moving backward facilitates the removal of the cast aluminum alloy wheel hub. This places high demands on the control precision of the drive mechanism of the wheel hub side module to prevent one wheel hub side module from being relatively ahead, causing adjacent wheel hub side modules to be relatively behind. If the side mold surface of the relatively behind wheel hub side module collides with the relatively ahead wheel hub side module, it will be damaged. Therefore, to avoid this misalignment of adjacent wheel hub side modules, we have specially designed a side module anti-misalignment structure. Summary of the Invention

[0003] To overcome the technical problems described in the background section, this utility model provides a wheel hub mold anti-misalignment structure. By setting a side notch on the wheel hub side module and fixing a bottom fixing plate to the ground with bolts, and setting an upright inter-block limiting block on the bottom fixing plate, the inter-block limiting block is embedded in two adjacent side notches, which can forcibly limit the forward movement of the wheel hub side module, improve the control safety of the wheel hub mold, and prevent the wheel hub side mold from moving too far forward, causing the side mold surface of the adjacent and relatively lagging wheel hub side module to collide with the relatively advanced wheel hub side module and be damaged.

[0004] The technical solution of this utility model is as follows: a wheel hub mold anti-misalignment structure, including a wheel hub side module, an inter-block limiting block, a bottom fixing plate and a through hole. The inclined surface of the wheel hub side module near the side mold casting surface is provided with a right-angle notch between the adjacent side surface. An inter-block limiting block is embedded between the side notches of two adjacent wheel hub side modules. The inter-block limiting block prevents the corresponding contacting wheel hub side module from moving forward without preventing the corresponding contacting wheel hub side module from moving backward. A horizontally extending bottom fixing plate is fixedly provided at the bottom of the inter-block limiting block. The bottom fixing plate is provided with a through hole for fixing to the ground by bolts.

[0005] Furthermore, vertical connecting plates are provided on the edges of the inter-block limiting blocks that do not contact the corresponding two wheel hub side modules, which serve to strengthen the connection.

[0006] Furthermore, the upper and lower ends of the edge of the inter-block limiting block that does not contact the corresponding two wheel hub side modules are respectively fixed with an upper connecting plate and a second bottom plate with triangular plate structure. An outer abutment plate is provided between the ends of the upper connecting plate and the second bottom plate away from the inter-block limiting block. The left and right ends of the outer abutment plate are respectively attached to the sides of the two wheel hub side modules.

[0007] Furthermore, the left and right ends of the outer backplate remain in contact with the corresponding wheel hub side modules during the movement of the corresponding wheel hub side modules.

[0008] The beneficial effects of this utility model due to the adoption of the above-mentioned technology are as follows: This utility model is fixed to the mold base by bolt connection of the bottom fixing plate. When the four wheel hub side modules are driven by their respective drive mechanisms to move, the inter-block limit block will not restrict the corresponding wheel hub side module from moving backward, but will accurately restrict the wheel hub side module from moving forward. In this way, even if one or more of the drive mechanisms of the four wheel hub side modules have control precision problems, causing asynchronous forward movement and some forward movement to exceed the speed, the inter-block limit block will forcibly limit the movement, improve the control safety of the wheel hub mold, and avoid the wheel hub side mold moving too far forward, causing the side mold surface of the adjacent and relatively lagging wheel hub side module to collide with the relatively advanced wheel hub side module and be damaged.

[0014] Example 1: As Figure 1 and Figure 2As shown, this utility model provides a wheel hub mold anti-misalignment structure, which is formed by welding steel and specifically includes a wheel hub side module 1, a first included angle limiting block 2, a bottom fixing plate and a through hole. During the casting of the wheel hub side module 1, a right-angle notch 6 is formed between the inclined surface near the side mold casting surface and the adjacent side surface. The first included angle limiting block 2 is embedded between the side notches 6 of two adjacent wheel hub side modules 1. The first included angle limiting block 2 serves to prevent the corresponding contact wheel hub side module 1 from moving forward without preventing the corresponding contact wheel hub side module 1 from moving backward. A horizontally extending first base plate 3 is welded to the bottom of the first included angle limiting block 2. The first base plate 3 is provided with a first fixing hole 5 for fixing to the ground by bolts.

[0015] Among them, a vertical connecting plate 4 is welded on the edge of the first included angle limiting block 2 that does not contact the corresponding two wheel hub side modules 1, which serves to strengthen the connection.

[0016] In this way, the first base plate 3 is fixed to the mold base by bolts. When the four wheel hub side modules 1 are driven by their respective drive mechanisms, the first included angle limit block 2 will not restrict the corresponding wheel hub side module 1 from moving backward, but will accurately restrict the wheel hub side module 1 from moving forward. In this way, even if one or more of the drive mechanisms of the four wheel hub side modules 1 have control precision problems, causing asynchronous forward movement and some forward movement to exceed the speed, the first included angle limit block 2 will forcibly limit the movement, improve the control safety of the wheel hub mold, and prevent the wheel hub side mold from moving too far forward and causing the side mold surface of the adjacent and relatively lagging wheel hub side module 1 to collide with the relatively advanced wheel hub side module 1 and be damaged.

[0017] Example 2: Figure 3 and Figure 4 As shown, this utility model provides a wheel hub mold anti-misalignment structure, which is formed by welding steel. Specifically, it includes a wheel hub side module 1, a second included angle limiting block 11, a bottom fixing plate and a through hole. During the casting of the wheel hub side module 1, a right-angle notch 6 is formed between the inclined surface near the side mold casting surface and the adjacent side surface. The second included angle limiting block 11 is embedded between the side notches 6 of two adjacent wheel hub side modules 1. The second included angle limiting block 11 prevents the corresponding contact wheel hub side module 1 from moving forward without preventing the corresponding contact wheel hub side module 1 from moving backward. A horizontally extending second base plate 10 is welded to the bottom of the second included angle limiting block 11. The second base plate 10 is provided with a second fixing hole 9 for fixing to the ground by bolts.

[0018] Among them, on the second included angle limiting block 11, the upper and lower ends of the edge that does not contact the corresponding two wheel hub side modules 1 are respectively welded with an upper connecting plate 8 and a second bottom plate 10 with triangular plate structure. An outer abutment plate 7 is provided between the ends of the upper connecting plate 8 and the second bottom plate 10 away from the second included angle limiting block 11. The left and right ends of the outer abutment plate 7 are always in contact with the corresponding wheel hub side module 1 during the movement of the corresponding wheel hub side module 1.

[0019] In use, based on the advantages of Embodiment 1, compared with Embodiment 1, since the two ends of the outer back plate 7 are always in contact with the side of the contacting wheel hub side module 1, the anti-overturning performance is better, and it is avoided from being knocked off by some extremely out-of-control wheel hub side module 1. The disadvantage is that the structure is slightly more complicated.
