Abstract
A tool (10) having improved heat transfer characteristics and a method for cooling a tool (10) which is comprised of several selectively coupled sectional members (12-17) Each selected sectional members (16) include an outer contour (19), while each of the sectional members (12-17) includes at least one coolant passage (14). These coolant passages (14) cooperatively form a coolant manifold (18) which is a predetermined distance from contours (19). An amount of coolant 40 is passed through manifold (18) to cool tool (10).
Claims17
A tool comprising a plurality of sectional members which are coupled together, wherein each of said plurality of sectional members have at least one coolant passage and wherein at least one of said sectional members has an outer contour which is disposed a certain predetermined distance from the coolant passage which is formed within said at least one sectional member.
A laminated tool having improved cooling characteristics, said tool comprising:
- a plurality of first sectional members each having a certain contour and at least one cooling passage which is a certain predetermined distance from said forming surface;
- wherein said plurality of sectional members are coupled together, effective to cause said certain contours to form a forming surface and to cause said at least one cooling passages to form a cooling manifold;
- and
- an amount of material which is disposed within said cooling manifold, effective to cool said tool.
A method for forming a tool having improved cooling characteristics, said method comprising the steps of:
- forming at least one first member having an first outer contour and at least one first inner passage which is disposed a certain minimum distance from said first outer contour;
- forming at least one second member having an second outer contour and at least one second inner passage which is disposed said certain minimum distance from said second outer contour;
- and
- attaching said at least one first member to said at least one second member wherein said first outer contour cooperates with said second outer contour to form a mold surface and said first inner passage is communicatively coupled to said second inner passage to form a manifold.
