Method for producing a tool
View Patent ↗A tool 10 which is made by a method which efficiently allows internal passageways, such as passageway 50 , which are at least partially circumscribed by thermally conductive material 103 , to be formed in the tool 10 , thereby allowing for enhanced cooling characteristics and allowing decreased cycle time and a reduced likelihood of damage to the formed object.
1. A method for producing a tool comprising the steps of:
creating a first sectional member with a first passageway formation portion;
creating a second sectional member with a second passageway formation portion;
coupling said first sectional member to said second sectional member in a manner effective to cause said first passageway formation portion to register with said second passageway formation portion, thereby forming a pre tool having an internal passageway; and
causing thermally conductive material to adhere to at least part of said internal passageway, thereby forming a tool from said pre tool, said tool having said internal passageway;
wherein said step of causing said thermally conductive material to adhere to said internal passageway further comprises the step of casting said thermally conductive material onto said internal passageway.
2. The method of claim 1 wherein said first sectional member and said second sectional member are formed from a substantially identical material.
3. The method of claim 2 wherein said substantially identical material comprises steel.
4. The method of claim 2 wherein said substantially identical material comprises aluminum.
5. The method of claim 1 wherein said thermally conductive material comprises copper.
6. The method of claim 1 wherein said thermally conductive material comprises conductive epoxy.
7. The method of claim 1 wherein said thermally conductive material comprises conductive graphite.
8. The method of claim 1 wherein said thermally conductive material comprises aluminum.
9. The method of claim 1 wherein each passageway formation portion is substantially identical.
10. The method of claim 1 wherein said coupling of said first sectional member to said second sectional member occurs by said thermally conductive material and occurs as said thermally conductive material adheres to said internal passageways.
11. The method of claim 1 further comprising forming an object by using the tool.
12. A method for producing a tool comprising the steps of:
creating a first sectional member with a first passageway formation portion;
creating a second sectional member with a second passageway formation portion;
coupling said first sectional member to said second sectional member in a manner effective to cause said first passageway formation portion to register with said second passageway formation portion, thereby forming a pre tool having an internal passageway; and
causing thermally conductive material to adhere to at least part of said internal passageway, thereby forming a tool from said pre tool, said tool having said internal passageway, wherein said thermally conductive material comprises the combination of powdered steel and copper which has been brazed to said internal passageway.
13. The method of claim 12 further comprising forming an object by using the tool.
14. A method for producing a tool comprising the steps of:
creating a first sectional member with a first passageway formation portion;
creating a second sectional member with a second passageway formation portion;
coupling said first sectional member to said second sectional member in a manner effective to cause said first passageway formation portion to register with said second passageway formation portion, thereby forming a pre tool having an internal passageway; and
causing thermally conductive material to adhere to at least part of said internal passageway, thereby forming a tool from said pre tool, said tool having said internal passageway;
wherein each sectional member includes a frame portion defining an internal area; and
wherein said first passageway formation portion includes a stem portion which is attached to said frame portion of said first sectional member and an open circular portion and wherein said second passageway formation includes a stem portion which is attached to said frame portion of said second sectional member and an open circular portion and wherein said method further comprises the steps of breaking each of said stem portions.
