Title:
CASTING MOLD SHAPING APPARATUS AND CASTING MOLD SHAPING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/195199
Kind Code:
A1
Abstract:
Provided are a casting mold shaping apparatus and a casting mold shaping method that make it possible to reduce equipment costs and to shape a mold by squeezing molding sand by means of a driving mechanism that employs an electric motor. This casting mold shaping apparatus comprises: a pressing member which, in a molding space formed by a carrier plate and a molding flask placed on a squeeze table, presses molding sand charged therein; a driving mechanism which performs driving so as to make the distance between the pressing member and the squeeze table close to or separated from each other and which is also equipped with an output unit which makes a relative movement along a direction in which the pressing member performs pressing; an electric motor which drives the driving mechanism; and a pressure adjustment device which makes an adjustment so as to cause a reduction in the force of the driving mechanism to be outputted to the output unit and to thereby cause the pressing member to generate a prescribed pressing force required for pressing the molding sand.
