Die vorliegende Erfindung betrifft ein Gießwerkzeug (60) zur Herstellung von Gusskörpern (20), mit mindestens zwei eine Gussform (61) bildenden Gussformteilstücken (32, 34), die, in einer Trennfläche (36) aneinander liegend, einen Gusshohlraum (38) umschließen und mit an den Gussformteilstücken (32, 34) angeordneten Innenoberflächen (40), die den Gusshohlraum (38) begrenzen und die durch ihre Gestalt die Raumform (42) des Gusskörpers (20) vorgeben. Ferner betrifft die Erfindung ein Verfahren zum Herstellen eines Gusskörpers mit einem gattungsgemäßen Gießwerkzeug. Um eine Vorrichtung bereitzustellen, mittels der Hinterschneidungen am Gusskörper (20) besonders einfach herstellbar sind, wird vorgeschlagen, dass zum Herauslösen des Gusskörpers (20) aus der Gussform (61) nach dem Aushärten des Gusskörpers (20) mindestens ein Teil (62) der am Gusskörper (20) anliegenden Innenoberfläche (40) von diesem unter zeitweiliger Veränderung ihrer Gestalt entfernbar ist.

| A method of making a metal shape comprising the steps of supplying molten metal into a ceramic shell mould mounted in a container, spinning the container and the shell mould therein about an axis and permitting the metal to solidify in the shell mould and thereafter removing, for example by breaking, the shell mould to expose the metal shape. The ceramic shell moulds made by providing a pattern of flexible elastically deformable material of a required shape and supported on a mandrel, applying at least one coating of hardenable refractory material to said pattern to form a rigid shell and removing the mandrel from supporting relationship with the pattern and subsequently removing the pattern from the shell by elastically deforming the pattern. The pattern is made by moulding said material in a master mould of a required shape and removing the pattern from the master mould, after the pattern has set, by elastically deforming the pattern | ||||||

A shell mold includes a plurality of sleeve forming portions. Of the sleeve forming portions, at least an endmost sleeve forming portion located adjacent to a subrunner portion has a modified shape for compensating for deformation of cast sleeves caused by solidification and contraction of molten metal. A shell molding apparatus includes an upper die and a lower die which constitute a die set for molding a shell mold. The lower die is composed of shell molding inserts, each having the shape of a halved cylinder, spiny insert receiving recesses formed in the shell molding inserts, and spiny inserts (22) retractably provided in the spiny insert receiving recesses. In a casting method using a shell mold, many protrusions of a spiny insert are reversely copied to the inner surface of a halved shell mold at the undercut portion of the inner surface, thereby forming many depressions at the undercut portion. The halved shell mold is parted form the lower die. A plurality of bore forming cores are disposed in the halved shell mold. The halved shell mold and another halved shell mold are engaged with each other, thereby forming a shell mold for casting. Casting is performed using the thus formed shell mold. |

Gußteile, deren Hohlräume später mit Beton gefüllt werden, wie z.B. Deckel für befahrbare Schachtabdeckungen, müssen eine innige und dauerhafte Verbindung mit dem Beton eingehen. Diese Verbindung wird erfingungsgemäß durch einen Vorsprung (5) verbessert, der an den Rand des offenen Hohlraums angegossen wird. Der Beton wird dann regelrecht verklammert und kann sich nicht mehr lössen. Um den vorsprung ohne Kern formen zu können, wird vorgeschlagen, entweder am Dauermodell einen nach außen zurückziehbaren Ring (6) vorzesehen oder den Formsand an der Stelle des Randvorsprungs nach dem Entformen mit einem Werkzeug (23) abzutragen. Auch ein verlorenes Modellteil (22) für den Vorsprung ist denkbar. |

| 78 | Self-aligned multipart combustible casting pattern and method of making same | US3635280D | 1969-11-07 | US3635280A | 1972-01-18 | PARSONS JOHN T |
| Combustible patterns of expanded polystyrene, carved to complex forms by the tape-controlled milling of two or more self-aligning parts, resist displacement from each other as sand is packed within and around them. Tongue-and-groove joints, formed on the mating surfaces of the parts, locate and align the parts and prevent their displacement more surely than adhesives, which tend to cause inclusions and voids in the casting. Adhesive may be coated on the tongue-and-groove parts only, leaving adjacent margins of the mating surfaces free from adhesive; and the exterior surfaces of the assembled pattern may be coated with a noncombustible ceramic coating. The marginal spacing of the adhesive inward from such coating permits quick dispersion of the adhesive when the molten metal is cast.

| A composite metal and flexible material pattern for making a sand mold, and in which the flexible material is used in the back draft area to thereby permit the use of a single pattern which can be removed without damage to the sand mold. The single pattern is made so that when the flexible material portion of the pattern is worn or damaged, it can be readily removed from the rest of the pattern, namely the rigid metal portion, and replaced with a new flexible material portion.
