The present invention relates to a method of removing a gate remnant from a casting comprising the steps of: providing a gating including a casting and a gate remnant, the gate remnant including a riser and at least two in-gates, wherein the at least two in-gates are attached to the riser and to the casting; weakening one of the at least two in-gates; and applying a first force to one of the at least two in-gates, wherein the first force severs the one of the at least two in-gates and thereby urges the riser away from the casting such that the other one of the at least two in-gates is severed, thereby separating the gate remnant from the casting.

Method of removing a gate remnant from a casting

A casting machine furnace apparatus that includes a furnace adapted to receive molten metal is described herein. The furnace includes an outer wall structure, a cover adapted to seal the furnace, a source of fluid, and a casting apparatus in fluid communication with the molten metal. The fluid is supplied into the furnace for applying fluid pressure on the molten metal. The application of fluid pressure on the molten metal causes the molten metal to supply the casting apparatus. The outer wall structure of the furnace is provided with a plurality of exhaust ports where the ports are provided in the outer wall structure at predetermined locations. The ports are selectively controllable between a first closed position, where the exhaust ports do not allow air to be exhausted from the furnace, and a second opened position, where the exhaust ports enable air to be exhausted from the furnace.

A safety block device for supporting a generally vertically movable component about a guide post of a press device. According to one embodiment of the invention, the safety block device includes a generally upright column () adapted to be disposed adjacent the guide post () and moveable between a retracted non-working position, wherein the column does not support the moveable component, and an extended working position, wherein the column is effective to support the moveable component and prevent movement thereof. The column includes an upper end portion and a lower end portion. According to one feature of the invention, the lower end portion of the column includes a generally rounded first portion () and a generally second flat portion () which is slightly offset with respect to the first portion. As a result of this, when the safety block device is in the extended working position, the generally flat second portion of the lower end portion of the column rests firmly on an underlying surface of either the safety block device or the press device.

A mold of a casting machine is filled to make a cast article. The method includes providing a molten metal to a casting chamber in fluid communication with the mold, the casting chamber having a supply conduit for introducing a gas into the casting chamber, and the casting chamber having an evacuation conduit for delivering the molten metal from the casting chamber to the mold. The method also includes controlling the filling of the mold during a first time interval by delivering the molten metal from the casting chamber to the mold at a first rate. The method further includes controlling the filling of the mold during a second time interval by delivering the molten metal from the casting chamber to the mold at a second rate. The filling of the mold decelerates from the first rate to the second rate and the second rate does not exceed the first rate.

Automated spin-casting system

An apparatus (10) for heat treat hardening multiple wear surfaces (24,26,28) of a metal workpart (14). Flame burners (38) and associated trailing quenches (36) travel along a linear and vertical path (13) across the workpart (14) to flame harden the wear surfaces (24,26,28) thereon. The workpart (14) is mounted on support studs (60) extending from a turntable (52), and clamping arms (66) securely engage the workpart (14) with the support studs (60). The turntable (52) rotates the workpart (14) relative to the travel path (13) of the flame burners (38) to move flame hardened surfaces (24,26,28) out of the travel path (13) and move unhardened surfaces (24,26,28) into the travel path (13) for flame hardening by the flame burners (38).
