摘要： A method of preparing a wax pattern for precision casting is proposed which comprises the steps of preparing a mould (2) consisting of two or more parts bearing the negative pattern of the surface of a master pattern (4), the mould (2) having an inlet opening, matching the parts of the mould (2) to one another, providing and melting a wax mixture including stearin and paraffin, pouring the wax mixture in molten state into the inner space of the mould (2), allowing the wax mixture to solidify and yielding a wax pattern, with the steps of encasing partly the master pattern (4) in a curable carrying material compostion (7) and leaving its surface partly free and preparing at least one matching element (3') on the surface of the carrying material composition (7) adjacent to the master pattern (4).

摘要： In a method of preparing a casting mould for precision casting, comprising the steps of preparing a pattern of destructible material on the basis of a master pattern (4), merging the pattern into fine sand of given density, drying the fine sand cover, repeating the merging and drying steps up to reaching a predetermined thickness of the cover, curing and firing the cover and destroying thereby the structure of the pattern, the novelty lies in the steps of preparing the pattern of destructible material as a wax pattern (11) of thin wall, making in the wall of the wax pattern (11) more holes (12) conncecting to each hole (12) a funnel type raising block (5) for determining an inlet passageway (16), merging the wax pattern (11) bearing the fine sand before drying into a fluidised bed containing a mixture comprising grains of corundum of first graininess, repeating the merging step up to reaching the predetermined thickness, arranging in the holes (12) respective locks (15) for connecting layers covering the inner and outer surfaces of the wax pattern, merging at least once the wax pattern (11) into fine sand of higher than given density, and spraying it with a mixture comprising grains of corundum of second, exceeding the first graininess, then melting wax (28) or wax mixture of the wax pattern (11) and firing the body consisted of an outer pattern (17) and inner core (18) maintained together by the locks (15).
摘要翻译：在制备精密铸造用铸模的方法中，包括以下步骤：基于母版图案（4）准备可破坏材料的图案，将图案合并成细密砂，使细沙层干燥，重复合并和干燥步骤达到盖的预定厚度，固化和烧制盖并因此破坏图案的结构，新颖性在于制备作为蜡图案（11）的可破坏材料的图案的步骤薄壁，在蜡图案（11）的壁上形成更多孔（12），其连接到每个孔（12），用于确定入口通道（16）的漏斗式提升块（5），合并蜡图案（11）在将干燥前的细沙干燥成含有含有第一颗粒状刚玉颗粒的混合物的流化床，重复合并步骤达到预定厚度，在孔（12）中设置各自的锁（15）用于连接覆盖蜡图案的内表面和外表面的层，至少将蜡图案（11）合并成高于给定密度的细砂，并用包含第二颗粒的刚玉超过第一颗粒度的混合物喷雾，然后熔融蜡（28）或蜡图案（11）的蜡混合物，并且由通过锁（15）保持在一起的外部图案（17）和内芯（18）组成。
