Abstract (en)
[origin: EP2508278A1] Provided in the present invention is a method and an apparatus for molding a mold that can make a cylinder for raising and lowering a table smaller. Also, the present invention can make the components that are required for the operation of the cylinder, etc., smaller. The apparatus comprises the following: a mechanism for raising and lowering via a table a pattern carrier located below a flask; a sand-providing mechanism for providing foundry sand into a space defined by the pattern plate of the pattern carrier and the flask; a squeezing mechanism for squeezing from above the foundry sand loaded in the space; and a fixing and releasing mechanism for fixing and releasing a component subject to squeezing power caused by a squeezing mechanism, and wherein the fixing and releasing mechanism fixes the component receiving the squeezing power to the end of the squeezing mechanism in a position above the raising and lowering mechanism.
