Mould residue removal from castings in mass prodn. - using high voltage discharges in water bath through which castings travel

Plant is used to remove mold residues from castings by high voltage discharges in a liq., e.g. water. A double chain conveyor, fitted with loading and unloading devices, carries the castings continuously through a zone (a) in the water bath; and the number of electrode units located in the treatment zone (a) is the same as the number of castings travelling through zone (a). The electrode units are pref. hinged on the conveyor frame so the electrode tips move together with the castings through zone (a), while driven gear wheels mounted on one side of the bath use grippers to rotate the castings while they travel through zone (a), i.e. so all the surface of each casting is treated to the electric discharge. Used esp. in mass prodn. to remove the residues of shell moulds from the castings, together with ingates, scale, rust, oil, etc., thus polishing the castings.

Riser topping gathering system and method

A riser topping gathering system and method are disclosed. The system and method are used in gathering riser topping material from the riser cavities of the cope portion of a mold. A capture hood includes high-pressure air outlets and is connected to a duct system, collector and air moving mechanism. The capture hood is moved into contact with the top of the cope mold portion. The air moving mechanism pulls a stream of ambient air over the top of the cope mold portion while high pressure air is pulsed into the riser cavities through the high air pressure outlets. The pulses of high-pressure air activate the riser topping materials and raise them out of the riser cavities and into the path of the ambient air in the capture hood. The moving ambient air carries the riser topping material out of the capture hood and into the duct system. The air and riser topping material is moved to the collector where the riser topping material is separated from the air. The riser topping material may then be gathered from the collector and disposed of or recycled. The cope mold portion may then be moved to another workstation for removal of the risers from the riser cavities.

The moulds contg. the castings are fed into the inlet end of the drum, and the sand leaves the outlet end of the drum at a lower level than a conveyor employed to remove the castings; and a hoist (a) is used to lift the castings so they are above their outlet conveyor. Hoist (a) may consist of baffle plates distributed round the outlet end of the drum; or electromagnets which lift the castings and are then switches off so the castings drop onto their outlet conveyor. The outlet end of the drum may possess a rim. Simple mechanical sepn. of the sand from the castings, where the latter can be carried by a short endless belt conveyor into a shot blasting cabinet or other appts. is provided.

Method for casting molded parts

Ein Verfahren zum Gießen von Formteilen umfasst folgende Verfahrensschritte: - Bereitstellen der Gussform (2), bestehend aus zu einem Kernpaket (1) komplettierten Kernen aus Formmaterial, - Positionieren des Kernpakets (1) in eine zu dem Kernpaket (1) beabstandete Stützform (3), - Hinterfüllen des Raumes zwischen dem Kernpaket (1) und der Stützform (3) mit einem rieselfähigen Schüttgut (5), - Gießen der metallischen Schmelze in die Gussform (2). - Öffnen oder Entfernen der Stützform (3) nach dem Erstarren der Schmelze, - zumindest weitgehendes Entfernen des Schüttguts (5) und - abermalige thermische Isolation des verbleibenden Kernpakets (1) mit dem darin befindlichen, bereits erstarrten Formteil (7). A method for casting molded parts comprises the following method steps: Providing the casting mold (2), consisting of cores of molding material, which are completed to form a core packet (1), Positioning the core packet (1) in a support form (3) spaced from the core packet (1), - backfilling of the space between the core package (1) and the support mold (3) with a free-flowing bulk material (5), - pouring the metallic melt into the mold (2). Opening or removal of the support mold (3) after solidification of the melt, - At least largely removing the bulk material (5) and - repeated thermal insulation of the remaining core package (1) with the therein already solidified molding (7).
