摘要： A storage vessel filled with a granular composition for forming mold parts has a bottom opening aligned with an opening in a pressure vessel located directly below the storage vessel. Upon being filled with the granular composition from the storage vessel, the pressure vessel is arranged so that the opening can be closed. The pressure vessel is movable vertically toward and away from the storage vessel. In its upper position it can be filled with the composition, and in its lower position can evacuate the granular composition into a cavity in a core molding device through nozzles situated at the bottom of the pressure vessel. The nozzles are directed into bores in the molding device and allow the granular material to exit when a compressed air source within the pressure vessel is activated.

摘要： In a system for the production of molds for casting, a pair of pattern plates are disposed in an opposed facing relationship with a frame located therebetween in a manner whereby the opposing pattern surfaces of the plates, together with the frame, define an enclosed cavity within which a casting mold section may be formed. The frame is preferably provided with an opening through which the cavity may be filled with molding material which, after hardening, forms a mold section. After separation of the pattern plates and frame, the mold section is conveyed into assembled relationship with one or more other mold sections in order to form a mold for casting. Pattern plates and frames may be arranged in a mass production facility to continuously form mold sections which, when assembled, will provide a mold stack for producing multiple castings.
摘要翻译：在用于生产用于铸造的模具的系统中，一对图案板以与位于其间的框架相对的对置关系设置，使得板的相对的图案表面与框架一起在其内限定了封闭的腔体可以形成铸模部分。框架优选地设置有开口，空腔可以通过该开口填充有模制材料，其在硬化之后形成模具部分。在分离图案板和框架之后，将模具部分与一个或多个其它模具部分输送成组装关系，以形成铸造模具。图案板和框架可以布置在批量生产设备中以连续地形成模具部分，其在组装时将提供用于生产多个铸件的模具堆叠。

摘要： The upper part of a foundry mold is manufactured by utilizing a pattern device which includes a gate pin having a guide hole therein which is adapted to engage a guide pin extending from the mold pattern of the foundry mold in order to retain the pattern device in place during production of the upper part of the foundry mold. An upper trough pattern may be mounted for axial movement relative to the gate pin. The upper trough pattern is configured to define a trough from which a plurality of gate pins may extend. By structuring at least two of the gate pins located at opposite ends of the trough with guide holes engaging guide pins extending from the mold pattern, rotation of the upper trough pattern about either of the guide pins may be prevented.

摘要： Foundry molds may be compressed and vibrated between a vibration table and a presser plate within apparatus which is structured to enable connection of the vibration table and the presser plate as a rigid frame during the compression and vibration process. The coupling means forming the rigid frame include locking means which may be actuated between a locked and an unlocked position whereby a gap may be formed when the coupling means are in the unlocked position to enable foundry molds to be swung in place by horizontally extending arms to effect location of the foundry molds between the vibration table and the presser plate. Damper means are also provided which damp and limit the movement of the presser plate and its associated pressure applying means in both an upward and a downward direction. In one embodiment the coupling means may comprise a vertically displaceable rod which may be actuated between a locked and an unlocked position between the presser plate and the vibration table, while in a second embodiment a swiveled lever involving a tongue-in-groove arrangement may perform the locking and unlocking function.

摘要： A system for handling pattern devices in molding apparatus for producing mold halves in mold boxes includes a rotatable transfer device having a pair of diametrically opposed tables whereby rotation of the transfer device will periodically shift the tables between a waiting position and an operating position located on opposite sides of the axis of rotation of the transfer device. A conveyor track system is provided having a portion thereof defined by conveyor track elements located on the tables. The conveyor track system includes an upper track section and a lower track section and the overall conveyor track system is formed to define a closed circulation path for the pattern devices.

摘要： Mold forming apparatus including a pattern device which is composed of pattern plates adapted to be operatively fitted into a pattern plate carrier is operated with the pattern device shifted between a lifting station, at which a formed mold may be removed from the patterns of the pattern plates, and an exchange station where the pattern plates may be separated from the pattern plate carrier for appropriate treatment thereof. The pattern plate carrier is formed in a generally box-like configuration with a bottom member having openings extending therethrough through which extraction pins of a lifting device may extend in order to raise and lower the pattern plates from the pattern plate carrier at the exchange station. A vacuum system is provided which will tend to hold the pattern plate carrier upon a bearing member of the apparatus and which will also tend to hold the pattern plate upon the pattern plate carrier while the finished mold is removed therefrom. An additional compressed air system operates to introduce air at the interface between the molds and the pattern plates in order to facilitate the separation thereof.
