Moulds reception.
At the line outlet, the sand cores reception is achieved through a vibrating conveyor especially designed to avoid sand adherence, by heating its surface.
The vibrating conveyor can be driven by two electric external vibrators, but eventually, natural frequency conveyors may be used if long distances or ascending angles up to 15º or more are required.
Natural frequency conveyors are especially apt for heavy-duty work, under very extreme conditions such as abrasion, shock or high charges.
Castings at a very high temperature can be conveyed, for which purpose special troughs are built, supported on the main frame by springs, which absorb the trough deformations, thusavoiding damage to the main frame.
The troughs can have very rugged grizzlies, bottom collectors, as well as intermediate discharge gates. One of the most usual operations is to transport red-hot castings and the separation of sand during conveying. Complete airtight, dust free installations are also manufactured.
These conveyors are of rugged design, giving trouble-free service, even under the direst conditions, furnishing high capacities and virtually maintenance free operation.
Their ruggedness enable them to transport materials of large size up to pieces of several hundred of kilograms.
The badly-palletised sand moulds can be recovered by a movable vibrating extractor, located perpendicular or parallel to the line.
The movable extractor can be driven pneumatically or with two geared motors.
Occasionally, a sand mould vibrating pattern drawing machine, carrying out the pattern drawing drum function, may be installed.
