Evanescent mode casting technology method for lightweight balance shaft beam

Abstract

The invention provides an evanescent mode casting technology method for a lightweight balance shaft beam. Specifically, firstly, according to the structural design of the lightweight balance shaft beam, connecting supports, thrust rod supports and the beam are of an integral structure cast and formed at a time, and a weight reduction structure is arranged; secondly, according to the design of a pouring system, a cross pouring gate and a straight pouring gate are connected, a pouring cup is arranged on the top of the straight pouring gate, three inner sprues are connected to the bottom of the cross pouring gate and connected with a product model, four slag collecting bags are divided into two groups arranged at the two ends of the product model, and chilling blocks are arranged at the positions, corresponding to the thrust rod supports, on the product model; thirdly, box embedding modeling is conducted; and fourthly, pouring is conducted. By means of the evanescent mode casting technology method, the pouring system is simple and compact in structure, modeling is convenient, a cavity is easily filled with molten metal, the defect that the impact resisting capability of existing balance shaft beams is commonly poor is overcome, and the purpose of casting of the integral structure is achieved.

Description

technical field [0001] The invention relates to a lightweight balance shaft beam lost foam casting process. Background technique [0002] Experiments have shown that if the weight of the vehicle is reduced by 10%, the fuel efficiency can be increased by 6%-8%; when the curb weight is reduced by 100kg, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6L. Reduce the self-weight of heavy trucks, reduce fuel consumption, reduce harmful substance emissions, save weight-based charges, increase load utilization coefficients, and increase transportation profits. After the weight of the car is reduced, the center of gravity of the car body can be lowered, and the driving of the car is more stable and comfortable. Lightweight can reduce rolling resistance, acceleration resistance and climbing resistance, and can also create conditions for realizing high power. Balance shaft suspension is one of the key components of commercial vehicles, and its lightweight design is n...
