Abstract
764,716. Moulding-machines. POLYGRAM CASTING CO., Ltd. Aug. 3, 1954, No. 22527/54. Class 83 (1). Apparatus for making moulds, hollow cores, &c. for foundry purposes comprises a pattern movable during the moulding operation, ejectorpins 4 for removing the mould from the pattern, and means 10 rendered operative at the cornmencement of movement of the pattern to prevent movement of the ejector-pins relative to the pattern. Members 10, 11 are fixed to a freely-pivoted shaft 9 below the pattern-table 3. As the table swings up to move the pattern over a sand-container 16, the member 10 is pushed by a fixed pin 14 so that it is jammed between the pattern-plate 3 and the ejectorplate 5. On the return movement, the member 11 is turned by a fixed pin 13 to free the ejectorplate.
