Topic The rubber make mold for casting experience study which the adult et. al who the visit is done, can be able do the experience study of casting safely in the child and the pupil and the museum etc apply appropriate die tightening power easily is offered.SolutionsDie body it designates 11 of the rubber make of two or more and 12 as the mold, rear board 13 provides on the rear of each die body. In addition, the melting point alloy is used for the metal which is poured in to the cavity of the mold low. It is low, the metal to until recently is not heated extent high temperature by using the melting point alloy, and also the te becomes good, compared to it is possible to do the experience study of casting safely. In addition, the die tightening power which is added to the mold, in order to put on the rear board which is provided on each rear of the die body, that power through the rear board, it joins to die body equally. Because of this, die body being the rubber, make it is possible to apply appropriate die tightening power easily, molding ones become distorted and/or it is possible to prevent the generation of trouble such that the liquefied metal starts neutron leakage.
