Abstract
A process relating to the pouring of molten metal into a permanent mould made of iron or other like material, automating the moulds within the system so as to offer diversification of production and while so doing having a finished product that is of a machinable and marketable nature. Slow cooling of the castings through the critical temperature in the system limits the formation of iron carbides and successfully produces a machinable product.
Claims5
A process of producing castings in a linear permanent mould casting system comprising the steps of:
- coating each of a plurality of moulds at a coating station with a suitable coating,
- forwarding each of said moulds to a core setting station, and closing said moulds,
- indexing each of said moulds to a time reading station and recording solidification time on said moulds and registering said time into a memory system,
- moving each of said moulds to a clamping station and clamping said moulds in a closed position,
- indexing said moulds to a pour station and filling said moulds with molten metal and starting said solidification timing,
- moving said moulds into solidification stations;
- unlatching and opening said moulds in accordance with the solidification time registered in the memory system and ejecting said castings onto a conveyor.
A linear, permanent mould casting system having means for indexing and moving each of a plurality of moulds linearly through a plurality of stations and comprising in series:
- (a) a coating station for coating each of said moulds;
- (b) a core setting station for setting cores when required;
- (c) a time reading station reading a solidification time from each of the moulds and registering said solidification time into a memory system so as to control the opening of said moulds;
- (d) a clamping station for securing each of said moulds in a closed position;
- (e) a pouring station with means for filling said moulds;
- (f) a plurality of cooling and unclamping stations controlled in accordance with the solidification time registered in the memory system for opening said moulds and for releasing castings therefrom;
- and
- (g) a shuttle for transferring each of said moulds to one end of a return track, means for conveying each of said moulds along the return track, and a second shuttle for transferring each of said moulds from the other end of the return track to the coating station.
