    • PURPOSE: A method for fabricating a mold for vacuum casting is provided to improve workability during piercing vacuum holes on the master model by pre-installing a plurality of vacuum pipes on a base during fabrication of a master model, thereby connecting the vacuum pipes to vacuum holes of the master model. CONSTITUTION: The method comprises first step (S10) of fabricating a base(1) corresponding to shape or size of a mold to be fabricated in order to do casting operation; second step (S20) of pre-installing a plurality of vacuum pipes laterally along the upper end of the base if the base is fabricated; third step (S30) of fabricating a pseudo-shape(5) for master model(7) of a mold to be fabricated by pouring casting molten metal into the base; fourth step (S40) of fabricating a master model having a product shape surface by NC machining the upper surface of the pseudo-shape(5) for master model; fifth step (S50) of surface treating the master model by accurately finish machining the product shape surface of the master model; and sixth step (S60) of piercing vacuum holes(11) connected to vacuum pipes(3) a plurality of which are included in the master model at several locations on the product shape surface(9) of the master model(7), wherein the casting molten metal is formed of molten zinc.
    • 目的:提供一种用于真空铸造的模具的制造方法,以通过在主模型的制造期间将多个真空管预先安装在基座上,从而提高在主模型上穿透真空孔期间的可加工性,从而将真空管连接到真空 主模型的孔。 构成:该方法包括制造对应于要制造的模具的形状或尺寸的基座(1)以进行铸造操作的第一步骤(S10) 如果制造底座,则沿着底座的上端横向地预先安装多个真空管的第二步骤(S20) 制造通过将铸造熔融金属注入基座而制造的模具的主模型(7)的假形状(5)的第三步骤(S30) 制造具有产品形状表面的主模型的第四步骤(S40),通过NC加工用于主模型的伪形状(5)的上表面; 通过精密加工主模型的产品形状表面来对主模型进行表面处理的第五步骤(S50) 以及第六步骤(S60),在主模型(7)的产品形状表面(9)上的多个位置刺穿连接到真空管(3)上的多个真空孔(11),其中多个包括在主模型中,其中 铸造熔融金属由熔融锌形成。
