摘要： The invention relates to a method for directly producing an investment casting mold by machining a sand mold produced using hardenable bonding agents. In particular, the wear of the tools should be reduced and the dimensional accuracy and precision should be increased during the reproduction of the mold. To this end, a blank mold (1) to be machined is produced while using a variable or fixed casting box (2) having a model assembly (4). Said blank mold comprises specified contours, with regard to volume, of the casting mold and a machining allowance for the milling of the molding material. After filling the casting box (2) with hardenable foundry molding materials, after hardening and after removal from the mold, the blank mold (1) is converted into the casting mold by removing material according to the machining allowance by means of high-speed machining, milling or three-dimensional machining of free-formed planes. The invention relates to investment casting molds for castings made of metal, and to the production of cast part prototypes and individual pieces having small and medium dimensions and masses.

摘要： The invention relates to a method for the uphill casting of cast pieces in sand dies with resinous, or, in particular, binder-containing cast cores and controlled solidification of metallic cast pieces, comprising at least one cavity. Said pieces are, in particular, prototypes of engine blocks, or cylinder heads, for example, for internal combustion engines, with a cavity for the throughflow of cooling water. In order to guarantee a low-turbulence flow of fluid metal melt on ventilating the cast mould, the cast mould (1), with at least one feed (24), is connected to a sprue cup (24) by means of a casting system (22) and the metal melt contained therein forced into the cast mould (1) through the casting system (22) by gravity. After filling the cavity (11') a vacuum is created in the metal melt, greater than the pressure of core gases generated in the core. Air cushions in the mould are, thus, prevented from impeding the filling of the mould and, by means of the above method, impervious, pore-free, mechanically sound cast pieces are produced.
摘要翻译： 描述了一种方法用于上坡铸造在砂模与高树脂铸芯或爱特别铸造含粘合剂核心，并用金属铸件定向固化thathave至少一个空腔。 特别地，本文是发动机缸体或气缸盖的原型，例如用于内燃机并设置有通过该冷却剂水流动的腔。 提供一种用于铸模的脱气过程中液体熔融金属的低湍流流动，铸模上设置有至少一个进纸器头也通过铸造系统在进料漏斗连接到，并且它包含在熔融金属是 通过铸造系统到铸模通过重力位移，以在熔融金属的空腔之后填充到减压所做的是比芯形成的芯气体的压力更大的经受。 这消除了妨碍在模具中填充气穴的模具。 在在Sametime，密实，无孔隙的，机械强度高的铸件是通过所述方法生产。
