Method for casting metals with melting points greater than 200° celsius using a plastic mold which mold conforms to the shape of the object to be cast used in conjunction with rapid cooling

Abstract

This present disclosure relates to a method for casting metals with melting points greater than 200° Celsius using a Plastic Mold which mold conforms to the shape of the object to be cast used in conjunction with Rapid Cooling.

1 . A method comprising:
 a mold constructed of plastic which mold incorporates at least one outer mold wall surface and at least one inner mold wall surface wherein inner mold wall surface encompasses a mold cavity;   
     
     
         2 . The method of  claim 1 , wherein there exist an inlet to the mold cavity allowing the introduction of molten metal into the mold cavity from without the mold; 
     
     
         3 . The method of  claim 2 , wherein there exist a conduit which directs the flow of a cooling fluid onto the outer mold wall surface thereby facilitating the removal of the heat of the molten metal from within the mold cavity into the cooling fluid, thereby cooling the metal within the mold cavity; 
     
     
         4 . The method of  claim 3 , wherein there may exist a mold outlet which facilitates the flow of metal and air from within the mold cavity to without the mold. 
     
     
         5 . A method comprising:
 forming a plastic mold for receipt of a molten metal with a melting point greater than 200° Celsius;   
     
     
         6 . The method of  claim 5 , wherein the plastic mold comprises a hollow interior between inner and outer walls, and wherein the hollow interior is configured to receive the metal for molding the molten metal between the inner and outer walls; 
     
     
         7 . The method of  claim 6 , further comprising a channel for communicating molten metal from without the plastic mold to said hollow interior; 
     
     
         8 . The method of  claim 7 , further comprising a channel for communication of a fluid to the outer walls of the plastic mold for the purpose of cooling the plastic mold. 
     
     
         9 . A method comprising:
 a mold for the casting of metals with melting points greater than 200° Celsius comprising;   a mold constructed of plastic which mold incorporates at least one outer mold wall surface and at least one inner mold wall surface wherein inner mold wall surface encompasses a mold cavity;   an inlet to the mold cavity allowing the introduction of molten metal into the mold cavity from without the mold cavity;   a conduit which directs the flow of a cooling fluid onto the outer mold wall surface thereby facilitating the removal of heat from the molten metal within the mold cavity through the inner mold wall surface proceeding through the outer mold wall surface into the cooling fluid, thereby cooling the metal within the mold cavity;   
     
     
         10 . The mold of  claim 9 , wherein there may exist a mold conduit or conduits which facilitates the flow of metal and air from within the mold cavity to without the mold cavity.
