Abstract

1,101,064. Isostatic moulding press. NATIONAL FORGE CO. 25 Oct., 1966 [22 Dec., 1965], No. 47769/66. Heading B5A. An isostatic moulding press for forming articles from powdered materials, comprises an outer fixed casing 10, having a feed inlet 11 and an outlet 12, within which is rotatably located an inner member 13. One portion of member 13 is provided with two diametrically oppositely disposed cored mould cavities 14, each of which has an expansible elastic liner, whilst the other portion is of reduced diameter and is provided with fluid containing radial bores which connect via passages 40 with each mould cavity. Radial pistons 29 are slidable within the bores and are actuated, through rollers 33, by a cam ring 25 eccentrically disposed within the space between the casing 10 and the reduced portion of the member 13. In operation, as member 13 rotates, a mould is filled at 11 and is carried round within the casing 10 to the outlet 12. During this time, the rollers 33 ride upon the part of cam ring 25 which is disposed nearest the centre of rotation. The associated piston is, consequently, initially forced into bore 28, the excess pressure being transmitted via passage 40 to the mould lining thus effecting the moulding, and is then withdrawn, thus releasing the pressure and enabling the finished article to drop, by gravity, through outlet 12.
