AI Technical Summary

Technical Problem

The existing aluminum alloy wheel hub weight reduction grooves need to be formed by machining, which results in low material utilization, long processing cycle and high cost, making it impossible to achieve efficient and lightweight production.

Method used

A side mold for weight reduction casting of aluminum alloy wheel hubs is designed. By sliding guide blocks and weight reduction blocks on the side mold, and utilizing the cooperation of guide grooves and inclined grooves, the weight reduction blocks can slide laterally and longitudinally. After the mold is closed, a convex ring is formed to directly form the weight reduction groove, replacing the machining method.

Benefits of technology

It improves production efficiency, reduces production costs, enables direct casting of wheel hub weight reduction grooves, meets lightweight requirements, and simplifies the production process.

Abstract

The application relates to the field of wheel hub casting, in particular to an aluminum alloy wheel hub weight-reducing casting side mold, a mold and a using method thereof, which comprises a side mold main body, a guide block, a weight-reducing block and a transverse driving assembly. The side mold main body is a semi-enclosing structure, the outer surface of one side of the side mold main body away from a placing side is a cavity side, the guide block is slidably connected to the inner side of the cavity, the weight-reducing block is slidably connected to one side of the guide block through a guide groove, the weight-reducing block can move transversely along the guide groove and can slide longitudinally along the guide groove; a hole is arranged on the cavity side corresponding to the moving direction of the end part, the end part of the weight-reducing block can pass through the hole; the inner side of the cavity of the side mold main body is symmetrically provided with inclined grooves corresponding to the two sides of the weight-reducing block, the two sides of the weight-reducing block are respectively connected with sliding blocks, and the sliding blocks are slidably matched in the inclined grooves; the shape of the weight-reducing block is such that the weight-reducing block is gathered into a convex ring after mold closing, so that the corresponding position of the wheel hub is directly formed into a weight-reducing groove after casting, and the mode of forming the wheel hub weight-reducing groove by machining in the prior art is replaced.
