Description

Technical Field

[0001] This invention belongs to the technical field of wheel hub mold support structure, and particularly relates to a deformation-resistant support device for wheel hub mold. Background Technology

[0002] Currently, in the manufacturing process of wheel hub molds, the side mold typically employs a four-combination arc-shaped block structure. This structure facilitates casting precision and efficient mold disassembly. In existing processes, this type of arc-shaped block combination structure is widely used in wheel hub casting, possessing good dimensional fit and mold forming capabilities, suitable for the production needs of various wheel hub specifications and complex structures. However, after mold manufacturing, long-distance transportation or long-term storage is often required. During this process, the mold is highly susceptible to various external environmental factors, especially the curved surfaces and splicing edges of the mold. Due to their precise structure and exposure, these areas become high-risk zones for physical and chemical damage. Common forms of damage include: 1. Physical deformation such as surface dents and scratches caused by collisions or extrusion; 2. Chemical damage such as rust caused by moisture, corrosion, or oxidation. Deformation of the mold in critical curved areas directly affects the casting precision, mold life, and product consistency of subsequent aluminum alloy wheels, leading to serious economic losses and quality problems. Therefore, existing transportation and storage methods usually require additional manual protection or temporary filling of cushioning materials, but these measures are often inefficient, non-reusable, and have limited protective effects. Summary of the Invention

[0003] In order to overcome the technical problems described in the background, the present invention provides a deformation-resistant support device for wheel hub molds, which is easy to install and reusable. It can provide effective support and protection for key parts such as the casting surface and splicing line of the wheel hub side module after the wheel hub side module is produced, thereby effectively reducing the risk of physical deformation or corrosion during transportation and storage.

[0004] The technical solution of the present invention is as follows: a deformation-resistant support device for a wheel hub mold, comprising a cover, an upper pressure rod, a lower support rod, a lower horizontal tube, an end connecting plate, and locking bolts. The top of the cover is provided with a dehumidification structure for drying the casting surface of the wheel hub side module. The left and right sides of the cover are respectively provided with upper pressure rods to form a top cover structure that covers multiple wheel hub side modules placed side by side with interconnected through holes. The upper pressure rod presses against the inclined side of the casting surface of the wheel hub side module. The lower support rod is provided directly below the upper pressure rod. Several lower horizontal tubes are provided between the two lower support rods to form a bottom support frame that supports the wheel hub side module. The top cover structure and the bottom support frame are respectively provided with end connecting plates at their front ends.

[0005] Furthermore, the dehumidification structure includes a dehumidification box, a perforated bottom plate, dehumidification blocks, and a sealing cover. The dehumidification box is located in the center of the cover and has a perforated bottom plate at the bottom. Several dehumidification blocks are placed on the perforated bottom plate, and the sealing cover is embedded in the upper opening of the dehumidification box.

[0006] Furthermore, a center rod passes through the through hole of the hub-side module.

[0007] Furthermore, the ends of the center rod, the upper pressure rod, and the lower bearing rod are respectively provided with end screws, and the end screws pass through the corresponding end connecting plates and the threaded portion of the end connecting plates is nested with locking bolts.

[0008] The beneficial effects of this invention due to the adoption of the above-mentioned technology are as follows: 1. The multi-dimensional rigid structure composed of the upper pressure rod, lower bearing rod, lower horizontal tube, end connecting plate and central rod achieves all-round constraint on the up-down, left-right, front-back and rotation directions of multiple wheel hub side modules, avoiding misalignment, offset, torsion and other situations of side modules during transportation or handling, thereby effectively preventing physical damage to the mold surface; 2. The cover and the built-in dehumidification structure work together to effectively cover the mold surface of the wheel hub side module, preventing direct contact between external air and moisture. At the same time, the activated carbon dehumidification block adsorbs moisture and controls the local environmental humidity, further reducing the risk of rust and corrosion on the mold surface, thereby improving the preservation quality and service life of the mold; 3. When lifting, steel cables are threaded through the lower horizontal tube to avoid the cover from participating in the load-bearing, which not only ensures that the cover structure will not affect the dehumidification performance due to load deformation, but also improves the safety and reliability of the overall lifting structure, realizing the separation of module functions and structural specialization.

[0014] Example 1: As Figures 1-4As shown, this invention provides an anti-deformation support device for a wheel hub mold, including a cover 2, an upper pressure rod 3, a lower bearing rod 5, a lower horizontal tube 6, an end connecting plate 7, and locking bolts 8. The top of the cover 2 is provided with a dehumidification structure for drying the casting surface of the wheel hub side module 4. The dehumidification structure includes a dehumidification box 11, a porous base plate 12, activated carbon dehumidification blocks 13, and a sealing cover plate 1. The dehumidification box 11 is located in the center of the cover 2 and its bottom is a porous base plate 12. Several activated carbon dehumidification blocks 13 are placed on the porous base plate 12. The upper opening of the dehumidification box 11 is embedded with the sealing cover plate 1. The left and right sides of the cover 2 are respectively provided with upper pressure rods 3, forming a top cover structure that covers multiple wheel hub side modules 4 placed side by side and interconnected by through holes 42. The upper pressure rods 3 The upper pressure rod 3 is positioned directly below the cast side slope 41 of the wheel hub side module 4, and a lower support rod 5 is positioned between the two lower support rods 5. Several lower horizontal tubes 6 are arranged between the two lower support rods 5 to form a bottom support frame that supports the wheel hub side module 4. The top cover structure and the front ends of the bottom support frame are respectively provided with end connecting plates 7. A central rod 9 is also provided between the two end connecting plates 7, which passes through the through holes 42 of multiple wheel hub side modules 4. The central rod 9 can prevent multiple wheel hub side modules 4 from moving up and down or left and right. The four-bar structure formed by the lower support rod 5 and the upper pressure rod 3 restricts the multiple wheel hub side modules 4 from rotating around the central rod 9. The two end connecting plates 7 restrict the multiple wheel hub side modules 4 from moving back and forth, thereby completely constraining the multiple wheel hub side modules 4.

[0015] The detachability between the end connecting plate 7 and the bottom support frame and the top cover structure is due to the fact that the ends of the center rod 9, the upper pressure rod 3 and the lower support rod 5 are respectively provided with end screws 10, and the end screws 10 pass through the corresponding end connecting plates 7 and the threaded part of the end connecting plate 7 is nested with a locking bolt 8.

[0016] When in use, after installing the hub-side module 4, it will be as follows: Figure 1 As shown, during lifting and loading, two steel cables are used to pass through two horizontally and vertically symmetrical lower horizontal pipes 6 with respect to the center of the cover 2. There is no need to set up special lifting lugs, and the cover 2 will not bear any load, ensuring the special use of the cover 2 and reducing the risk of damage to the molded surface of the wheel hub side module 4. Since the cover 2 covers the molded surface of the wheel hub side module 4 and uses a dehumidification structure for dehumidification, it avoids rust and damage to the molded surface of the wheel hub side module 4, further reducing the risk of damage to the molded surface of the wheel hub side module 4.
