Abstract

856,196. Moulding-machines. OSBORN MANUFACTURING CO. Feb. 20, 1959 [March 5, 1958], No. 5948/59. Class 83 (1). A foundry squeeze-moulding-machine has supplementary means for squeezing the sand in the flask, comprising at least one rigid probe carrying an inflatable member for insertion within the sand. The machine comprises a hopper 26 with gates 27, 28 controlled by pistons 29, 30, from which sand is dumped into a measuring bin 31. The bin outlet is controlled by a louvred gate 32 actuated by a cylinder 33, so that the sand may be dumped into the flask 38 and fill frame 39, which flask and frame are moved into and from the machine on rollers 36, 37. The squeeze-head 15 is reciprocable into and out of operative position on rollers 16 by pistons 20, and comprises a number of squeezeplates 50, some or all of which carry rigid probes P, each comprising an inflatable balloon 58, Fig. 7, e.g. of neoprene, which may be inflated by pressure fluid supplied through inlet 61. The cavities produced by the inflation of the members 58 serve as gas vents, or they may be filled by sand-blowing. In a modification, probes may be inserted through the sides of the flask to obtain a more uniform compaction. They may also be mounted on the pattern plate. The sand may be jolted or vibrated before the squeezing. Specification 787,005 is referred to.
