Abstract

PURPOSE: To obtain a hollow casting without any inconvenience such as remaining of casting sand without requiring any core by joining the members which are divided the thin-walled hollow object of approximately the same shape as the internal shape of the hollow casting to a suitable number, mounting the same in a mold and pouring molten metal into the spacing between said member and mold.
CONSTITUTION: In order to produce a hollow casting such as cylinder head of automotive parts, the thin-walled hollow object constituting members 1a, 1b of the shape comprising by dividing, for example, a thin-walled hollow object to two parts are manufactured respectively through die-casting. These are combined and brazed to form a thin-walled hollow object 2. This is mounted in the mold 3 consisting of upper and lower metal molds 3a, 3b and molten metal is poured from a sprue part 4 into the casting spacing 5 formed between the thin-walled hollow object 2 and both metal dies 3a, 3b. After this has frozen, both metal dies 3a and 3b are opened and the hollow casting 6 is taken out. Its sprue portion 7 and gas vent portions 7 are removed by the cutting lines (l), whereby it is made into the product.
