Abstract

Disclosed herein, amongst other things, is a component of a molding system, and a related method for the manufacture thereof, that has a body with a support matrix defined in at least a portion thereof.

First claim

What is claimed is:

1. A nozzle of a molding system, the nozzle comprising:
a nozzle body; and
a nozzle tip disposed at a front part of the nozzle body;
wherein the nozzle comprises a support matrix defined in at least a portion thereof, the support matrix forming a porous structure.

2. A nozzle of a molding system, the nozzle comprising:
a nozzle body; and
a nozzle tip disposed at a front part of the nozzle body;
wherein the support matrix includes a three-dimensional web of structural supports and
wherein a spacing between structural supports varies such that voids that are defined between the supports gradually change in volume across the web of supports.

3. The nozzle of claim 1 , wherein the support matrix includes a filler material disposed therein.

4. A nozzle of a molding system, the nozzle comprising:
a nozzle body; and
a nozzle tip disposed at a front part of the nozzle body;
wherein the nozzle comprises a support matrix defined in at least a portion thereof, and
wherein voids defined in the support matrix are evacuated.

5. The nozzle of claim 3 , wherein the filler material has a different thermal conductivity than a base material of the support matrix.

6. The nozzle of claim 5 , wherein the filler material has a thermal conductivity that is higher than that of the base material.

7. The nozzle of claim 3 , wherein the filler material is a mixture of different materials.

8. The nozzle of claim 7 , wherein the filler material is a mixture of industrial diamond dust and copper powder.

9. The nozzle of claim 1 , wherein the support matrix has a density gradient defined therein that is oriented such that a density of the support matrix increases towards a surface of the nozzle.

10. The nozzle of claim 1 , wherein the support matrix includes a base portion having a low density and a transition portion that is arranged between the base portion and the surface of the nozzle, wherein the density of the transition portion changes from the low density of the base portion to a fully dense structure across a width thereof.

11. The nozzle of claim 1 , wherein the nozzle defines a melt channel for distributing, in use, molding material to a mold.

12. The nozzle of claim 1 , wherein at least a portion of the nozzle tip comprises the support matrix.

13. The nozzle of claim 12 , wherein the nozzle tip includes at least a front portion having the support matrix with a filler material therein.

14. The nozzle of claim 12 , wherein the support matrix includes a density gradient that increases towards surfaces of the nozzle tip.

15. The nozzle of claim 13 , wherein the support matrix is formed from a relatively strong material that supports a relatively weak material, wherein the relatively weak material is more thermally conductive than the filler material.

16. The nozzle of claim 12 , further comprising a seal ring disposed adjacent the nozzle tip, wherein the seal ring includes a support matrix.

17. The nozzle of claim 16 , wherein the support matrix in the seal ring includes a filler material having a lower thermal conductivity than a material forming the seal ring.
