Reshaping and ejecting device for automobile rear axle

Abstract

The invention discloses a shaping and mold stripping device for a rear axle of an automobile. The device comprise the rear axle (1), a shaping center positioning device (2), an outer shaping mold fixed mold (3), an outer shaping mold moving mold (6), a shaping guiding moving platform (7) and rear axle mold stripping devices (8), wherein the two rear axle mold stripping devices (8) are arranged at two ends of the rear axle (1) and push the rear axle (1) oppositely to move in a radial direction of the rear axle (1). According to the device, an inner cavity structure of a shaping mold is changed freely according to dimensions of the rear axle of the automobile so as to meet requirements of various rear axle products of the automobile; the rear axle mold stripping devices control axial and radial platform movement through position sensing systems, and then workpieces are ejected easily through ejection rods. The whole device is simple in structure, safe, practical, simple to operate and high in yield, so that a new solution is provided for shaping and mold stripping of the rear bridge products of the automobile.

Description

technical field [0001] The invention relates to the field of automobiles and vehicles, in particular to a shaping and ejecting device for rear axles of automobiles. Background technique [0002] The rear axle of a car refers to the device behind the car that connects the frame and the wheels. If it is a vehicle driven by the front axle, the rear axle is a follower axle and only plays the role of carrying. If the front axle is not a drive axle, then the rear axle is a drive axle. In addition to carrying the load, it also plays the role of driving, deceleration and differential speed. If it is a four-wheel drive, it is generally equipped with a transfer in front of the rear axle. device. [0003] The front axle and the rear axle refer to the front and rear axles. The front axle includes shock absorbers, steering gears, balance shafts, etc., and the rear axle also includes drive shafts and transmission gears. The rear part of a multi-axle truck is divided into a drive rear a...

AI Technical Summary

Problems solved by technology

However, after the shaping is completed, due to the close cooperation between the rear axle and the center positioning device, it is difficult to release the mold. Therefore, the mold release process is basically completed by manpower, and the degree of automation is low.

Many people use the principle of leverage to release the rear axle from the center positioning device. The workload is heavy and the productivity is low, which limits its market promotion prospects. It will also affect the surface quality of the middle section of the rear axle and indirectly or directly affect the subsequent processing procedures.
