Embodiment 1
[0092] 26-inch, A356 alloy wheels. H13 steel mold, upper mold + lower mold + 4 side mold structure, directly exposed to the atmosphere. The pouring temperature is 710°C, the initial mold temperature is 400°C, and the cooling method is air cooling.
[0093] The steps of preparing aluminum alloy wheels by adopting metal mold low-pressure casting molding with crystallization pressure-holding and boosting method include:
[0094] Step 1, liquid ascending stage;
[0095] Under the condition that the liquid lifting pressure is 20kPa and the liquid lifting speed is 2.0kPa / s, the aluminum liquid rises steadily along the liquid rising pipe to the gate of the mold and flows into the mold;
[0096] Step 2, the filling stage;
[0097] Under the conditions of the filling pressure of 30kPa and the filling speed of 0.75kPa / s, the molten aluminum is filled into the cavity from the gate until the cavity is completely filled;
[0098] Step 3, crystallization pressurization stage;
[0099] Af...
