Abstract
1289124 Casting machines CINCINNATI MILLING MACHINES Ltd 13 Jan 1970 [20 Feb 1969] 9208/69 Heading B3F [Also in Division B5] In a two-stage closing device for die casting dies 1, 2, initial closing is effected by fluid admitted through an inlet 17 and bores 20, 13 into a chamber 6a in a piston 6 to move the piston and a die 2 into contact with a die 1, and final clamping is effected by fluid acting in a chamber 9a on an annular face of the piston 6. During the initial closing hydraulic fluid is drawn by gravity into the chamber 9a through an inlet 18 past a valve 44, 45 as indicated by arrow 48. For the final clamping pressure a sleeve 38 is moved axially from the position shown in the upper half of Fig. 2 to that in the lower half, to close the valve 44, 45. The sleeve 38 is moved by means of plungers 27a, 27b operated by fluid admitted at 35a. Hight pressure fluid is then supplied through inlet 17, bores 24a, 24b, ports 28a 1 , 28b 1 , along axial bores 29a, 29b of the plungers 27a, 27b for delivery from ports 31a, 31b to the passageway 14 and chamber 9a.
