ABSTRACT:
A carbon block molding machine which automates the heating, compressing and cooling steps which previously were done by hand. A mold unit has an inner sleeve for receiving the mixture of granular carbon particles and the hinder. A pressure unit compresses the granular carbon particles and binder in the sleeve. A heating unit integrally heats the sleeve to melt the hinder to bond the compressed carbon particles to form the carbon block within the sleeve. Preferably, a cooling unit cools the sleeve for removal of the finished carbon block. A programmed control unit selectively controls operation of the pressure unit, the heating unit and the cooling unit so that the heating unit is activated while the pressure unit compresses the granular carbon particles and the hinder. The heating unit is preferably a two-piece heater that is maintained at an elevated temperature and selectively moved into contact with the sleeve to heat the sleeve.
