Embodiment Construction
[0021] A kind of method of V-method molding process casting production glass mold blank, concrete process steps are as follows:
[0022] 1) Blank material: adopt the heat-resistant alloy cast iron material independently developed by our company as AD-VTFe-20-F to cast glass mold blanks. The chemical composition of the heat-resistant alloy cast iron is: C 3.3% ~ 3.8%, Si 1.9%~2.5%, Mn 0.5%~0.6%, P 0.06%~0.07%, S 0.02%~0.03%, Mo 0.5%~0.9%, V 0.1%~0.2%, Ti 0.2%~0.4%, Cr 0.1 %~0.2%, Mg 0.002%~0.004%, Cu 0.1%~0.2%, Zn 0.003%~0.004%, Al 0.03%~0.04%, Ni 0.4%~0.6%, and the rest is Fe;
[0023] 2) Form plate and mold core: adopt the overall aluminum alloy form plate designed and processed by our company; each V-method vacuum pumping box upper box is equipped with 4 freely replaceable form cores, and each form core has 2 half-piece assembled mold cores. The shape of the mold core can be combined with multiple aluminum alloy modules of different parts and sizes according to the shape an...
