Abstract
878,469. Feeding mouldable thermosetting materials. HARRIS METALS TREATING CO. Aug. 18, 1958, No. 26513/58. Class 87(2). [Also in Group XXII]. A thermosetting material, e.g. a resin-sand mixture, is fed into a heated cavity via a tube connected at one end to the cavity and closed at the other, and having an air pressure supply connected adjacent its closed end, to force the mixture into the cavity ; said tube being pivoted adjacent said closed end to move the open end from the cavity to a recharging position. A vertical tube 24 has its lower end threaded into a sleeve 17 which is closed by a threaded member 16, and is locked, with its upper end beneath a stationary throat member 25 leading into a cavity 26 defined by metallic dies 27, 28 located between heated platens 29, 30, by a stem 15 which contacts the lower face of member 16 when pressure is applied to cylinder 13. Air pressure is applied to hose 31 and the desired quantity of the column of the resin-sand mixture is compactly forced into cavity 26 and cured. The column is recharged by relieving the pressure in cylinder 13 and pivoting tube 26 to one side about trunnions 19 movable slots 20 in struts 21, and refilling tube 24.
