A torsion bar type aluminum alloy overturning bearing casting mold and process

Abstract

The invention relates to a torsion bar type aluminum alloy overturn support casting mold and technology, including an upper mold, and a correspondingly arranged lower mold, which is used for pouring molten aluminum. The second step; the first top surface of the first step has a first part cavity for forming the base part of the overturned support; the second top surface of the second step has a second part shape for forming the force-bearing part of the overturned support Cavity; the transition surface between the first top surface and the second top surface has a third part of the cavity for forming the connection part of the flip support, and a positioning pin for placing the connection sleeve on the second part of the cavity ; The casting process adopts gravity tilting casting, and the mold and process of the present invention can produce torsion bar type flip bearings with high strength and high elongation.

Description

Technical field[0001]The present invention relates to an aluminum alloy casting, and more particularly to a mold and process of a torsional aluminum alloy flip holder casting.Background technique[0002]In order to meet the needs of engine maintenance, maintenance, most commercial trucks are connected to the frame by flipping mechanisms. For the torsion bar flip mechanism, the torsion bar needs to be preloaded to the flip holder in the flip holder, and is locked with a lock mechanism. When the cab is required to flip the cab, the torque is released from the flip holder, and is transmitted to the cab.[0003]Therefore, the flipping support not only functions connect the cab and the frame, but also provides a twisted force for the cabling, is a key security structure. At present, commercial vehicles in the market are generally used as cast steel or sheet metal welding, and the weight of the cast steel is heavier, and the sheet metal welding results in the structure of the welding. For exa...

Problems solved by technology

With the development of automobile lightweight, the overturning support is made of aluminum alloy, but the strength of the aluminum alloy overturning support prepared by the prior art is not good, especially the fixed connection position between the torsion bar and the overturning support. Large torque is prone to failure. In order to meet the needs of practical applications, a mold and process for casting high-strength and high-elongation torsion bar aluminum alloy flip supports is required.
