Abstract (en)
[origin: EP2316625A2] The method involves providing a base body made of foam material, and machining the base body according to negative geometry of a channel so as to form female molds (130, 138) by a machining process. The female molds are inserted into a basic mold (154). The body is milled to the female molds to accurate size by the machining process. The basic mold is provided with an offset increase (161) that corresponds to an offset section (163) of a shaft bottom piece. The female molds are formed from a mixture including a sand material and a bonding agent. The bottom piece is made of concrete. An independent claim is also included for a device for producing a mold for manufacturing shaft bottom pieces.
