PARTIAL CONTACT BETWEEN HEATER ASSEMBLY AND HOT-RUNNER MANIFOLD

ASSEMBLY

TECHNICAL FIELD

An aspect generally relates to (but is not limited to) a mold-tool system and/or a molding system having the mold-tool system.

SUMMARY

The inventors have researched a problem associated with known molding systems that inadvertently manufacture bad-quality molded articles or parts. After much study, the inventors believe they have arrived at an understanding of the problem and its solution, which are stated below, and the inventors believe this understanding is not known to the public. The current problem is that electrical resistive heater assemblies supply a fixed wattage per linear length of the heater assembly. Known installation method depends on installing the heater assembly to have good thermal conductance to a manifold of a runner assembly. This arrangement may improve heat transfer. However, heat transfer is a two way street, not only does the above arrangement improve heat going out to the manifold from the heater assembly, but the above arrangement may also improve cooling of the heater assembly at the location of heat losses. For an ideal case, the temperature of the electric heater is to be independent of the temperature of the manifold. However, the next best case may be to limit the effect of the manifold temperature on the temperature of the heater assembly. Instead of transferring a majority of the heat by conductance, the solution may reduce, at least in part, heat transfer by conduction and/or may improve heat transfer by radiation. Radiative heat transfer is a function of the fourth power of temperature difference between two bodies (using an absolute scale), and thus is much higher for larger differences in temperature. This then acts as a partially self-regulating heat transfer mode, as the amount of heat transferred increases dramatically as the temperature differential increases, and correspondingly decreases as the temperature differential decreases. This is in contrast to conductive and convective heat transfer modes, where the heat transfer typically has a linear relationship as a function of the temperature differential. The ideal resistive heater design combines conductive, convective and radiative heat transfer modes, with the contribution of each dependent upon numerous parameters, including but not limited to, materials, desired temperature profiles, environmental conditions, etc. To resolve the above, at least in part, according to a first aspect, there is provided a mold- tool system (100), comprising: a partial-contacting means (106) for partially contacting a heater assembly (104) with a hot-runner manifold assembly (102).

To resolve the above, at least in part, according to a second aspect, there is provided a mold-tool system (100), comprising: a hot-runner manifold assembly (102); a heater assembly (104); and a partial-contacting means (106) for partially contacting the heater assembly (104) with the hot-runner manifold assembly (102).

To resolve the above, at least in part, according to a third aspect, there is provided a mold- tool system (100), comprising: a hot-runner manifold assembly (102); and a heater assembly (104), the hot-runner manifold assembly (102) and the heater assembly (104) being in partial contact with each other.

To resolve the above, at least in part, according to a fourth aspect, there is provided a method, comprising: partially contacting a heater assembly (104) with a hot-runner manifold assembly (102). The mold-tool system (100) may improve heat transfer and may decrease power draw, and may improve thermal uniformity.

Other aspects and features of the non-limiting embodiments will now become apparent to those skilled in the art upon review of the following detailed description of the non-limiting embodiments with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS

The non-limiting embodiments will be more fully appreciated by reference to the following detailed description of the non-limiting embodiments when taken in conjunction with the accompanying drawings, in which:

FIGS. 1 to 15 depict schematic representations of examples of a mold-tool system (100).

The drawings are not necessarily to scale and may be illustrated by phantom lines, diagrammatic representations and fragmentary views. In certain instances, details not necessary for an understanding of the embodiments (and/or details that render other details difficult to perceive) may have been omitted.

DETAILED DESCRIPTION OF THE NON-LIMITING EMBODIMENT(S)

FIGS. 1 to 15 depict the schematic representations of the examples of the mold-tool system (100). The mold-tool system (100) may include components that are known to persons skilled in the art, and these known components will not be described here; these known components are described, at least in part, in the following reference books (for example): (i) Injection Molding Handbook authored by OSSWALD/TURNG/GRAMANN (ISBN: 3- 446-21669-2), (ii) "Injection Molding Handbook authored by ROSATO AND ROSATO (ISBN: 0-412-99381 -3), (iii) "Injection Molding Systems" 3 rd Edition authored by JOHANNABER (ISBN 3-446-1 7733-7) and/or (iv) "Runner and Gating Design Handbook authored by BEAUMONT (ISBN 1 -446-22672-9). It will be appreciated that for the purposes of this document, the phrase "includes (and is not limited to)" is equivalent to the word "comprising". The word "comprising" is a transitional phrase or word that links the preamble of a patent claim to the specific elements set forth in the claim that define what the invention itself actually is. The transitional phrase acts as a limitation on the claim, indicating whether a similar device, method, or composition infringes the patent if the accused device (etc) contains more or fewer elements than the claim in the patent. The word "comprising" is to be treated as an open transition, which is the broadest form of transition, as it does not limit the preamble to whatever elements are identified in the claim.

The definition of the mold-tool system (100) is as follows: a system that may be positioned and/or may be used in an envelope defined by a platen system of the molding system (known and not depicted), such as an injection-molding system for example. The platen system may include (and is not limited to) a stationary platen and a movable platen that is moveable relative to the stationary platen.

Examples of the partial-contacting means (106) are described below and depicted in the FIGS.

More specifically (in accordance with an option), the partial-contacting means (106) may provide effective contact between the hot-runner manifold assembly (102) and the heater assembly (104) is reduced by at least 25% as a result of the hot-runner manifold assembly (102) and the heater assembly (104) being in partial contact with each other, in comparison to a case in which the hot-runner manifold assembly (102) and the heater assembly (104) are in normal contact with each other. Referring generally to all of the FIGS., broadly speaking in accordance with a third example the mold-tool system (100) includes (and is not limited to): a hot-runner manifold assembly (102), and a heater assembly (104), in which the hot-runner manifold assembly (102) and the heater assembly (104) are in partial contact with each other.
