Title: Arrangement for compensating for changes in metallostatic pressure in machines for casting with gas pressure
IPC: B22D18/08
Filed: 1972-04-20
Abstract: 1383102 Pressure casting machines INSTITUTE PO METALOZNANIE I TECHNOLOGIA METALITE 20 April 1972 [29 April 1971] 18470/72 Heading B3F [Also in Division F1] The circuit shown in Fig. 2 compensates for changes in metallostatic pressure in a machine for casting with gas pressure, the changes being due to changes in the level of metal in a crucible. An input signal, indicating a casting operation, is received at an input 15 and formed into a pulse by a shaper 1. Logic circuit A constitutes a ring counter, which can be re-set, and produces an output pulse after a predetermined number of castings has been produced. The logic circuit B comprises a shift-register which is actuated by each output pulse of the circuit A and controls a logic circuit C. The latter is operable to produce a compensation signal causing a control circuit of the casting machine to stop changing the difference in pressure between the mould and the crucible. A differential manometer senses the pressure difference between mould and crucible and also controls the production of the compensation signal. Assuming a first batch of castings has been produced and circuit B has received a first pulse, circuit B operates so that a first OR gate, e.g. 22, produces an O signal. This causes nozzle 33 to be fed with gas from a source H150. At output 57 there is produced a compensation signal, and when the manometer, Fig. 2 (not shown), senses the predetermined pressure defined by the signal path having nozzle 33, a barrier (59) blocks the nozzle 33 causing the control circuit to stop the change of pressure.
