At the place where the upper and lower cores form a diaphragm, chromite ore sand is used to replace ordinary

The diaphragm is connected with the main body of sand casting, stiffener, middle annular structure, oil passage and boss, resulting

The sand casting material of gearbox shell is ZL114A aluminum alloy, with high requirements for mechanical properties: tensile strength ≥

The shrinkage porosity produced in the solidification process of sand castings is mainly predicted by using the shrinkage porosity criterion.

Generally speaking, the higher the pouring temperature of sand casting, the better the fluidity of alloy liquid and the more

Because the deformation of blade sand casting is difficult to predict and control, and the deformation of blade sand casting

The setting of simulation parameters is the same as that of mold filling process. After setting, the calculation and Simulation

From the simulation results of traditional gating system, the following two aspects should be paid attention to when designing the

After the pretreatment, the mold filling simulation experiment of blade sand casting will be carried out. The simulation results are

For the same sand casting, different pouring speed corresponds to different pouring time. In the process of molten metal entering

The pouring position of sand casting usually refers to the position of the axle housing in the mold during pouring.
