TOOL AND METHOD TO CREATE AN ACCURATE CAST OF THE INTERNAL FORM OF A COMPONENT

A molding tool ( 10 ) has a body ( 20 ) that can be inserted into a cavity ( 62 ) of a component ( 12 ) for introducing molding material ( 72 ) to form a mold of one or more internal surfaces ( 60 ) defining the cavity ( 62 ). The molding material ( 72 ) is at least partially cured with the tool ( 1...

Beschreibung
Zusammenfassung:	A molding tool ( 10 ) has a body ( 20 ) that can be inserted into a cavity ( 62 ) of a component ( 12 ) for introducing molding material ( 72 ) to form a mold of one or more internal surfaces ( 60 ) defining the cavity ( 62 ). The molding material ( 72 ) is at least partially cured with the tool ( 10 ) in place so that the mold ( 80 ) and tool ( 10 ) are removed from the cavity ( 62 ) as a single unit. The tool ( 10 ) includes a passage ( 34 ) for introducing the molding material ( 72 ) into the cavity ( 62 ). A pressure device, such as a plunger ( 50 ), may be used to force the molding material ( 72 ) through the passage ( 34 ) and into the cavity ( 62 ). The tool ( 10 ) also serves to support the mold ( 80 ) on a fixture or other structure used to analyze the mold ( 80 ) to verify characteristics of the form, such as, for example, an optical comparator.
