specific Embodiment approach 1
[0023] Specific implementation mode one: combine Figure 1 to Figure 3 To illustrate this embodiment, a semi-continuous anti-gravity pouring method for an aluminum alloy automobile frame described in this embodiment includes the following steps:
[0024] Step 1: aluminum alloy smelting treatment: perform aluminum alloy smelting, refining, and degassing treatment at the smelting station, and inject the treated aluminum alloy into the crucible 27 in the lower tank 1 for use;
[0025] Step 2: Pre-treatment of the mold: spray paint on the upper half mold 10, the upper mold cavity 11, the core 14, the lower mold cavity 15 and the lower half mold 16, and prepare the riser pipe 23 at the same time, and produce The on-site commander sends an order to the operator of the control center to start pouring;
[0026] Step 3: Horizontal movement of the lower tank: After receiving the pouring order, the operator in the control center manually presses the start button, the trolley 3 carrying ...
