Abstract: 1,066,833. Moulding machines. T. J. HILLIARD. June 26, 1964, No. 26448/64. Heading B3F. A moulding machine comprises a pair of draw plates 20 movable toward and away from each other along fixed paths, each draw plate having at least one elongated gripping ridge 27 engaging with a mould cope or drag plate, all of said ridges being parallel and perpendicular to the path of movement of the draw plates, and pattern plate means movable to and from a position between said draw plates, the said pattern plate means being co-operable with the draw plates to provide a pair of mould-halfforming cavities, means for supplying sand-resin mix to said cavities, hardening means, and means for exerting a force parallel to said ridges on the formed mould halves to eject them from the draw plates. A machine for forming and assembling mould sections A, C, and cores B comprises a pair of horizontally movable draw plates 20 and a pair of horizontally and vertically movable mounting plates 40 supporting core box halves 42 and patterns 41. In operation the mounting plate assemblies are lowered to a position between the draw plates by means 60, and the draw plates and mounting plate assemblies simultaneously moved horizontally together to form a complete mould and core box assembly as shown in Fig. 3, by cylinders 21 and a screw mechanism 52-55 respectively. A sand-resin mix is then blown into the cavities through openings S 1 -S 3 , Fig. 3, from a blowhead 72, and cured therein by heaters in the draw plates and mounting plates. The draw plates and mounting plates are then retracted horizontally, the mould halves A, C, being retained on their respective draw plates by engagement with ribs 27, and the core, which, as shown, comprises several sleeve coupling cores united by top and bottom members B 1 , is held stationary by retaining members 30. The mounting plate assemblies engage in the lifting members slots 63a and are lifted so that the mould parts can be closed on to the core B. The ribs 27 and retaining members 30, while preventing lateral movement of the mould and core parts, allow the mould and core assembly to be pushed endwise from between the draw plates by means 80, and are tapered to assist this action. For forming non-cored moulds pattern surfaces are substituted for the core box halves to produce a central mould member which in co-operation with the mould parts A, C, produces two parallel moulds which may be poured simultaneously or independently.
