Abstract
1288037 Casting-machines BRITISH NON- FERROUS METALS RESEARCH ASSOCIATION 22 Oct 1969 [23 Oct 1968] 50266/68 Heading B3F [Also in Division B5] A pressure die-casting machine or a gravitycasting machine has means for determining, in accordance with the temperature at a point in the casting, in the slug or in the runners or the die adjacent to the casting, the moment of automatic opening of the dies. When the temperature has fallen to a certain level, a signal derived from a sensor is used to initiate a die-opening sequence. At least one sensor such as a thermocouple 14 is placed near the cavity surface or in an insert protruding into the cavity and operates a switch 14/1. There may be a sensor in the shot sleeve of a cold-chamber machine. Opening of the dies 10 is effected by an hydraulic ram 11 operable by way of an electrical supply 30 (when the contact 15/1 of a timer 15 is closed) controlled by a manual switch 18 or temperature-controlled contacts 22/2, 24/2 actuated by relays 22, 24. When the temperature of sensor 14 first rises above the required temperature, contact 22/2 is opened and contact 24/2 closed and it is not until the sensor temperature falls again that contact 22/2 closes to complete the circuit. The timer 15 is short circuited or set to ensure closure of its contact 15/1 to render the control temperature-dependent. When the dies open, a contact 35 is closed to re-set the circuit for another cycle.
