ABSTRACT:
A press is disclosed for use in the manufacture of refractory products and particularly including means for causing reciprocal movement of cores into the mold cavity to thereby permit holes to be formed in the compressed refractory product. The core moving apparatus is conveniently attachable and removable from the press to permit removal or replacement of the mold box or to facilitate modification of an existing press to incorporate the means of the invention for causing movement of reciprocal cores. The core supporting structures of the core moving apparatus are also adjustably supported so as to accommodate varied numbers of cores or various arrangements of the cores.
