Benefits of technology

The patent text discusses a method for reducing heat loss and the chance of damage to a pattern mold during transportation. The text proposes the use of a cradle to support the mold during loading and a funnel feature at the top of the main gate to allow for faster and more repeatable cycle times. This method would result in faster and more consistent part production.

Problems solved by technology

Vacuum induction smelting and vacuum electric arc smelting require the use of a water-cooled copper crucible which results in the loss of substantial heat.
Furthermore, the preparation of the molding shell is very complex and time consuming, which adds to the costs.
The molten titanium liquid will come into direct contact with water if the crucible cracks, resulting in a fierce reaction, or even explosion, which poses a great threat to production safety.

Embodiment Construction

[0033]As shown in FIG. 1, a unit cell titanium casting system 5 comprises an external container 44, an internal container 39, a vacuum mechanism 60, a crucible 10, an induction coil 15, a coil electrical generation mechanism 25, and a mold 30. The external container 44 defines an external chamber 45. The internal container 39 defines an internal chamber 40. The vacuum mechanism 60 includes a vacuum line 71, a vacuum connector 70 and pressure gauges 75a and 75b. The vacuum mechanism 60 is utilized to evacuate and pressurize the external chamber 45 and the internal chamber 40 in order to create a pressure differential between the internal chamber 40 and the external chamber 45.

[0034]The crucible 10 is preferably composed of a ceramic material. In a most preferred embodiment, the crucible10 is composed of a first layer 11a, a second layer 11b and a silica based third layer 11c, as shown in FIG. 7. A metal ingot 20 is placed within the interior of the crucible 10. The metal ingot 20 is ...

Abstract

A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).
