Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wheel hub casting molds, in particular to a wheel hub casting mold with an integrated water tank. Background Art
[0002] With the increasing popularity of automobiles, China is gradually becoming a global automobile production base. As a critical safety component, the wheel hub bears the pressure from the vehicle and its load, the dynamic torque during starting and braking, and the irregular alternating forces generated by dynamic loads from various directions, such as cornering, uneven roads, and impacts from road obstacles. A wheel hub primarily consists of the rim, spokes, and center hub. Wheel hub molds are generally divided into low-pressure casting and gravity casting molds.
[0003] In the existing technology, the cooling design of the low-pressure hub casting mold is achieved by making a metal annular cooling water channel geometry that meets the size, and then assembling the water trough geometry onto the mold to fit the surface of the part that needs to be cooled and tightening it with bolts to make it fit tightly. The heat of the mold is taken away by controlling the circulation time of air and water. However, due to the long-term high-intensity thermal shock of the water trough geometry, thermal stress deformation and cracking will occur, resulting in a loose fit. The inside of the water trough will also crack due to the high-frequency thermal shock. The cracked and deformed cooling plate needs to be opened for a longer time for air and water circulation to obtain qualified products, and may even lead to an increase in unqualified products, wasting energy and costs.
