Abstract

1,150,377. Moulds. AMSTED INDUSTRIES Inc. 17 Nov., 1966, No. 51606/66. Heading B3F. A mould 10 mounted on a deck 58 of a car 44 for movement to and from a pressure pouring station 70, 72, comprises two halves, 12, 14 clamped together during pouring and slidable as a unit along support bars 50, 51 to interrupt pouring, the two halves of the mould also being slidable on the bars 50, 51 away from each other to extract the casting from the mould. The mould halves are made of graphite with copper chill plates 60 at the bottoms and are mounted in a framework 20 having adjustable clamps 24 and bearings 56, 57 slidable on the bars 50, 51. The bars 50 at the bottom of the framework 20 hold the mould tightly on to the deck of the car 44. The mould or mould halves are moved by two pairs of hydraulic ram devices selectively applied to the mould or mould halves at stations (a)-(d) (Fig. 6, not shown) through which the car 44 moves. One pair of rams are pushers and are mounted in cradles (80), (82) (Fig. 2, not shown) for pushing the mould halves together and for moving a complete mould to cut-off pouring; the other pair of rams are pullers that separate the two halves of the mould and are similarly mounted in the cradles (80), (82).
