Abstract
1,032,412. Casting-machine moulds. FOX & OFFORD Ltd. June 4, 1962 [June 3, 1961], No. 20112/61. Heading B3F. [Also in Division B5] A bolster for holding removable moulds for use in injection moulding or die casting machines comprises two members 6, 7 movable towards and away from each other, one member or each member being formed with one or more channels 22, each channel opening towards the other member and having at least one end operable so that a mould impression half can be introduced into and removed from the channel and the walls of the channel being so shaped as to co-operate within mould half or a clamp for a mould half to prevent the mould half from leaving the channel, and closure means for closing the ends of the channel and tightenable screw means engaging the moulds or clamps to prevent movement of the moulds along the channel. As described, the channels are formed between supports 15 having a wide body portion 18, a narrow neck portion 19 and a head portion 20 of width between that of the body and neck. Appropriate moulds are provided with flanges which (a) fill the portion between head and body as in 38, or (b) fill only a part of said portion, the rest being filled by a spacer, as in 53, or (c) have not sufficient width to protrude beneath the head portion and are held by clamps (Figs. 4, 5, not shown) as in 62. The channels may include ejector means formed by bars 23 connected at their protruding ends to ejection means on the appropriate injection moulding or die casting machines and cooperating with rods 40 which pass into the moulds and are coupled to plates 43 engaging the bars 23. The upper member 6 may be as shown or may be similar to member 7. The channels are closed by bars removably connected to supports 15 and containing bolts (Fig. 1, not shown) passing through the bars to bear on the moulds or clamps to prevent movement of the moulds along the channels. The supports may carry electrical heating means 33.
