sand casting

After any liquid metal is injected into the mold, it goes through three interrelated shrinkage stages from pouring temperature to

1. Model transformation and mesh generation The coupler body and sand casting process are modeled by proe and exported by

The coupler knuckle is connected with the coupler body through the coupler knuckle pin. During the operation of the vehicle

After the production line of type 16 knuckle product is arranged and runs well, the trial production of the product

The hook tongue adopts the improved sand casting process scheme to simulate the mold filling and solidification process. The pouring

There are 14 sand cores in the motor shell in total, and the assembly of sand cores is shown in

① Analysis on the original pouring system of motor shell See Fig. 1 for the original pouring system of motor

Before the proportion of molding sand is proposed, the basic range of molding sand properties should be determined according to

The defect distribution of sand castings after processing is shown in Figure 1, figure 2 and figure 3. The sand

After the sand casting is cleaned, the fluorescent wet magnetic particle flaw detection is carried out. The total number of

The quality status of castings after sand dropping and shot blasting in the two sand mold casting process tests is
