Mold-tool system having a manifold body defining uninterrupted melt channels
View Patent ↗A mold-tool system comprising: a manifold assembly, including: a manifold body defining: an inlet assembly; outlets being set apart from the inlet assembly; and uninterrupted melt channels extending between the inlet assembly and the outlets.
1. A mold-tool system ( 100 ), comprising:
a melt-distribution assembly ( 102 ), including:
a manifold body ( 104 ) defining:
an inlet assembly ( 106 );
outlets ( 108 ) being set apart from the inlet assembly ( 106 ); and
uninterrupted melt channels ( 110 ) extending between the inlet assembly ( 106 ) and the outlets ( 108 ),
wherein the uninterrupted melt channels ( 110 ) have no melt-channel intersections between the uninterrupted melt channels ( 110 ) so that there is no mixing of a melt between the uninterrupted melt channels ( 110 ),
whereby each of the outlets ( 108 ) have similar heat profiles.
2. The mold-tool system ( 100 ) of claim 1 , wherein:
the inlet assembly ( 106 ) includes a single inlet; and
the uninterrupted melt channels ( 110 ) connect each of the outlets ( 108 ) to the single inlet.
3. The mold-tool system ( 100 ) of claim 1 , wherein:
the inlet assembly ( 106 ) includes inlets ( 107 ); and
the uninterrupted melt channels ( 110 ) extend between the inlets ( 107 ) and the outlets ( 108 );
each of the uninterrupted melt channels ( 110 ) having an exclusive inlet and outlet being selected from the inlets ( 107 ) and the outlets ( 108 ), and the exclusive inlet and outlet are unassociated with any other uninterrupted melt channel.
4. The mold-tool system ( 100 ) of claim 1 , wherein:
each of the uninterrupted melt channels ( 110 ) continues uninterrupted from a dedicated inlet and a dedicated outlet.
5. The mold-tool system ( 100 ) of claim 1 , wherein:
the inlet assembly ( 106 ) is configured to divide a flow of melt from to the outlets ( 108 ) into geometrically symmetrical portions equivalent to a number of outlets ( 108 ).
6. The mold-tool system ( 100 ) of claim 1 , wherein:
the melt-distribution assembly ( 102 ) includes:
an upper melt-distribution assembly ( 102 A) having the uninterrupted melt channels ( 110 A);
a plurality of lower melt-distribution assemblies ( 102 B) each having the uninterrupted melt channels ( 110 B);
the upper melt distributor assembly ( 120 A) is attached to the upper melt-distribution assembly ( 102 A); and
the plurality of lower melt distributor assemblies ( 120 B) connects the upper melt-distribution assembly ( 102 A) to the plurality of lower melt-distribution assemblies ( 102 B).
7. The mold-tool system ( 100 ) of claim 1 , wherein:
each of the uninterrupted melt channels ( 110 ) is a single contiguous melt channel from inlet to outlet for each drop leading into a mold cavity of a mold assembly.
