Abstract

750,980. Moulding-machines. TACCONE, R. W. June 16, 1954, No. 17699/54. Class 83(1). A moulding-machine comprises a head having a wall 27 forming an open cavity closed by a flexible diaphragm 34 which may be moved into engagement with moulding-material in a flask 19, the area of the diaphragm being substantially greater than the cross-sectional area of the mould-box, and exceeding that necessary to conform to the surface of the moulding material, so that no tension results in the diaphragm when in the moulding position. The flask is carried on a vertically-movable support 13 and the diaphragm is forced into engagement with the sand by pressure-fluid supplied through a valve 3a to a chamber 25 in the head, connected to the cavity behind the diaphragm by holes 28 in the wall 27. Between moulding operations, the diaphragm is held up in the head-cavity by suction applied to the chamber 25 through a valve 38. In a modification, Fig. 5, chambers 74, 75 and pressure-fluid connections 84, 85 serve to inflate the side portions of the diaphragm to ensure that the edges of the sand in the flask are firmly packed. In a further modification, Fig. 6, the diaphragm 103 is of accordian type.
