Abstract

787,005. Moulding-processes. OSBORN MANUFACTURING CO. May 3, 1956 [July 8, 1955], No. 13708/56. Class 83 (1). A moulding-process comprises blowing a preformed sand-mould about a pattern within a box, drawing said mould and pattern as a unit from the box, placing a flask about said mould, and squeezing the mould within the flask. The blower, Fig. 2, comprises a table 7, supported on a piston 5 and carrying a platen 8, pattern-plate 9 and pattern 10, the latter including a boss 11 &c. to form a sprue-passage for the mould, which is used in stack moulding. The preformed mould P is drawn from the box 20, which has inwardly tapering walls, by lowering the table 7 and the assembly of platen 8, pattern-plate 9, pattern 10 and mould P, and transferred to the table 28, Fig. 4, of a squeezemachine. A flask 36 having inclined walls is placed around the mould and the mould forced against the squeeze-plate 35 to distribute the excess sand standing above the flash wall. The mould and flash are stripped on rods 42. The mould may be jolted or vibrated prior to the squeezing.
