Abstract

1316120 Casting-machines FISHER GAUGE Ltd 29 Sept 1970 [10 Oct 1969] 50011/69 Heading B3F A pressure die casting machine comprises an injection nozzle 15; a frame 10 having die parts 16, 17, 19 and 21; means 11 supporting the frame 10 and being movable between a lowered position in which the die gate 40 seats on the nozzle 15 and a raised position; and means for floating and anchoring the frame 10 on the support 11. The support 11, Fig. 2, comprises a yoke 25 located about a pillar 26 and pivotally attached thereto via a channel link 32. The frame 10 is supported on plates 38 attached to the yoke, said plates having cavities 39 connected with fluid pressure means. Before initiating the cyclical operation of the apparatus pressure fluid is supplied to the cavities 39 to enable the position of the frame 10 to be adjusted before it is secured to the plates 38. The cyclical seating and unseating of the die gate 40 on the nozzle 15 is carried out by the drive mechanism 42, Fig. 3. This consists of arm 43 pivoted at one end to the channel link 32 and at the other end eccentrically to a wheel 44 driven by a rack 44 and pinion 45. A stop pin 50 bears against the arm 43 when the latter is in its lower position and the die gate is seated on the nozzle as shown in Fig. 3. An anti-clockwise movement of the wheel 44, from the position shown in Fig. 3, raises the arm 43 thus causing the channel link 32 to rotate and move the yoke 25 to the left. Since the end of the yoke is pivoted to a fixed plate 28, this causes a raising of the yoke 25 and thus unseats the die gate from the nozzle. The die plate 19 may then be moved horizontally by pistons 91 to sever the plug in the gate 40 from the casting. The die part 16 is attached to the end of a shaft 60 which is movable by means of a piston ring 75 in an hydraulic cylinder 76, Fig. 6. Within the shaft 60 is a further shaft 77 carrying a collar 78 supporting a ring 65. A second ring 64 is mounted adjacent to the end of shaft 60, both rings having notches therein to accommodate guide keys 62. To close the die, the shafts 60 and 77 are moved to the left until they reach the position shown in Fig. 6, at which point the ring 64 remains keyed whereas ring 65 is located in a recess 62a in the guide keys 62 and is rotated by a finger (68) to move its notches out of alignment with the keys 62. Hydraulic cylinders 71 are then actuated to move wedges 70 against latches 63 which pivot about a pin 63a and bear against the ring 65 so as to lock the die part 16 in position. The apparatus may be used for encapsulating a turbine blade in a block of metal, the blade being located and held within the die cavity by fixed and movable locating pins (106), (110), (104) and (111), the movable pins being moved in and out of the cavity by means of a lever (118), Fig. 8 (not shown), and locked in position by means of a rod 82 extending through the shaft 77 and operated by an hydraulic cylinder 81. The die parts are water-cooled and the lower die part 19 is provided with an aperture 92 through which a lubricant is injected into the die.
