ASSEMBLY TO THE HEAT-RECEIVING BODY IS IMPROVED

TECHNICAL FIELD

Aspects generally relate to (and not limited to) mold-tool systems including (and not limited to) molding systems.

BACKGROUND

United States Patent Number 4771164 to GELLERT, issued 13 September 1988, entitled "Injection molding nozzle and method," discloses an injection molding nozzle and a method of making it.

United States Patent Number 7703188 to FEICK, issued 27 April 201 0, entitled "Thermal shroud and method of making same," discloses an injection molding hot runner nozzle and a method of making such a nozzle.

SUMMARY

Some manufacturers of known molding systems may braze (at least in part) a known heater assembly into a manifold groove defined by a known manifold assembly, and/or cast the heater assembly into an aluminum alloy used in the manifold assembly. Known heater assemblies (used with the known manifold assemblies) may: (i) inadvertently leave some air between the heater assembly and the manifold assembly of a known runner assembly (air acts as a thermal insulator), (ii) reduce contact pressure at the interface between the heater assembly and the manifold assembly (which reduces heat transfer), and/or (iii) produce inconsistent heating of the manifold assembly (which may lead to unbalanced resin flow in the known manifold assembly). Air is functionally equivalent to a thermal insulator. Any air or air pocket (located between the heater assembly and the manifold assembly) acts to: (i) slow (reduce) heat transfer from the heater assembly to the manifold assembly, (ii) permit overheating of the heater assembly (which tends to reduce the operational life of the heater assembly), and/or (iii) cause inconsistent heating of the manifold assembly (by way of irregular amounts or pockets of air positioned between the heater assembly and the manifold assembly).

In order to resolve, at least in part, the above-noted issues, according to a first aspect, there is provided a mold-tool system (100), comprising: a body (106) being configured to be positioned, at least in part, between a heater assembly (102) and a heat-receiving body (104), and the heater assembly (102), the heat-receiving body (104) and the body (106) having coefficient of thermal expansions such that heat transfer from the heater assembly (102) to the heat-receiving body (104) is improved.

In order to resolve, at least in part, the above-noted issues, according to a second aspect, there is provided a mold-tool system (100), comprising: a body (106) being configured to be positioned, at least in part, between a heater assembly (102) and a heat-receiving body (104), and the body (106) being formed from a swaging process to facilitate heat transfer such that heat transfer from the heater assembly (102) to the heat-receiving body (104) is improved. The swaging process uses a swaging force (109).

In order to resolve, at least in part, the above-noted issues, according to a third aspect, there is provided a mold-tool system (100), comprising: a heater assembly (102); a heat-receiving body (104) being configured to receive, at least in part, the heater assembly (102); and a body (106) being positioned between the heater assembly (102) and the heat-receiving body (104), the heater assembly (102), heat-receiving body (104) and the body (106) having coefficient of thermal expansions such that heat transfer from the heater assembly (102) to the heat-receiving body (104) is improved.

In order to resolve, at least in part, the above-noted issues, according to a forth aspect, there is provided a method of manufacturing a mold-tool system (100), the method comprising: swaging the body (106) into an intervening space being located between the heater assembly (102) and the heat-receiving body (104); driving out as air (as much as possible) between the heater assembly (102) and the heat-receiving body (104); work hardening the body (106); and retaining the heater assembly (102) in the groove (107) of the body (106).

In order to resolve, at least in part, the above-noted issues, according to a forth aspect, there is provided a method of manufacturing a mold-tool system (100), the method comprising: applying a body (106) to a heater assembly (102), placing the body (106) combined with the heater assembly (102) in a groove (107) of a manifold assembly (917) of a runner system (916), and swaging the body (106) into an intervening space located between the heater assembly (102) and a surface of the groove (107), so that much of the air is removed from an interface between the heater assembly (102) and the manifold assembly (917). 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.

FIGS. 1 and 2 depict example schematic representations 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)

Generally speaking, FIGS. 1 and 2 depict example schematic representations of the mold- tool system (100).

More specifically, FIG 1 depicts an example of a schematic representation of the molding system (900), and an example of a schematic representation of a mold-tool system (100). The molding system (900) may also be called an injection-molding system for example. According to the example depicted in FIG. 1 , the molding system (900) includes (and is not limited to): (i) an extruder assembly (902), (ii) a clamp assembly (904), (iii) a runner system (916), and/or (iv) a mold assembly (918). An assembly means: (i) a collection of parts so assembled as to form a complete machine, structure, or unit of a machine, and/or (ii) a group of machine parts, especially one forming a self-contained, independently mounted unit. By way of example, the extruder assembly (902) is configured, to prepare, in use, a heated, flowable resin, and is also configured to inject or to move the resin from the extruder assembly (902) toward the runner system (916). Other names for the extruder assembly (902) may include injection unit, melt-preparation assembly, etc. By way of example, the clamp assembly (904) includes (and is not limited to): (i) a stationary platen (906), (ii) a movable platen (908), (iii) a rod assembly (910), (iv) a clamping assembly (912), and/or (v) a lock assembly (914). The stationary platen (906) does not move; that is, the stationary platen (906) may be fixedly positioned relative to the ground or floor. The movable platen (908) is configured to be movable relative to the stationary platen (906). A platen-moving mechanism (not depicted but known) is connected to the movable platen (908), and the platen-moving mechanism is configured to move, in use, the movable platen (908). The rod assembly (910) extends between the movable platen (908) and the stationary platen (906). The rod assembly (910) may have, by way of example, four rod structures positioned at respective corners of the stationary platen (906) and the movable platen (908). The rod assembly (910) is configured to guide movement of the movable platen (908) relative to the stationary platen (906). A clamping assembly (912) is connected to the rod assembly (910). The stationary platen (906) is configured to support (or configured to position) the position of the clamping assembly (912). The lock assembly (914) is connected to the rod assembly (910), or may alternatively be connected to the movable platen (908). The lock assembly (914) is configured to selectively lock and unlock the rod assembly (910) relative to the movable platen (908). By way of example, the runner system (916) is attached to, or is supported by, the stationary platen (906). The runner system (916) includes (and is not limited to) a mold-tool system (100). The definition of the mold-tool system (100) is as follows: a system that may be positioned and/or may be used in a platen envelope (901 ) defined by, in part, an outer perimeter of the stationary platen (906) and the movable platen (908) of the molding system (900) as depicted in FIG. 1. The molding system (900) may include (and is not limited to) the mold-tool system (100). The runner system (916) is configured to receive the resin from the extruder assembly (902). By way of example, the mold assembly (918) includes (and is not limited to): (i) a mold-cavity assembly (920), and (ii) a mold-core assembly (922) that is movable relative to the mold- cavity assembly (920). The mold-core assembly (922) is attached to or supported by the movable platen (908). The mold-cavity assembly (920) is attached to or supported by the runner system (916), so that the mold-core assembly (922) faces the mold-cavity assembly (920). The runner system (916) is configured to distribute the resin from the extruder assembly (902) to the mold assembly (918).

In operation, the movable platen (908) is moved toward the stationary platen (906) so that the mold-cavity assembly (920) is closed against the mold-core assembly (922), so that the mold assembly (918) may define a mold cavity configured to receive the resin from the runner system (916). The lock assembly (914) is engaged so as to lock the position of the movable platen (908) so that the movable platen (908) no longer moves relative to the stationary platen (906). The clamping assembly (912) is then engaged to apply a camping pressure, in use, to the rod assembly (910), so that the clamping pressure then may be transferred to the mold assembly (918). The extruder assembly (902) pushes or injects, in use, the resin to the runner system (916), which then the runner system (916) distributes the resin to the mold cavity structure defined by the mold assembly (918). Once the resin in the mold assembly (918) is solidified, the clamping assembly (912) is deactivated so as to remove the clamping force from the mold assembly (918), and then the lock assembly (914) is deactivated to permit movement of the movable platen (908) away from the stationary platen (906), and then a molded article may be removed from the mold assembly (918).

On the one hand, the mold-tool system (100), the molding system (900), and the runner system (916) may all be sold separately. That is, the mold-tool system (100) may be sold as a retrofit item (assembly) that may be installed to an existing molding system (not depicted) and/or an existing runner system (not depicted). In accordance with an option, it will be appreciated that the mold-tool system (100) may further include (and is not limited to): a runner system (916) configured to support (or configured to position) the mold-tool system (100). In accordance with an option, it will be appreciated that the mold-tool system (100) may further include (and is not limited to): a molding system (900) having a runner system (916) configured to support (or configured to position) the mold-tool system (100). In accordance with an option, it will be appreciated that the mold-tool system (100) may further include (and is not limited to): a molding system (900) configured to support (or configured to position) the mold-tool system (100). On the other hand, the mold-tool system (100), the molding system (900), and the runner system (916) may all be sold, to an end user, as an integrated product by one supplier.

Generally speaking, with reference to FIG. 2, the mold-tool system (100) includes (and is not limited to): a body (106) configured to be positioned, at least in part, between a heater assembly (102) and a heat-receiving body (104). The heater assembly (102), the heat- receiving body (104), and the body (106) have coefficient of thermal expansions such that heat transfer from the heater assembly (102) to the heat-receiving body (104) is improved. Examples of the coefficient of thermal expansions for the above elements are provided below. A technical effect for the mold-tool system (100) (for the case where coefficient of thermal expansions are utilized) is improved heat transfer from the heater assembly (102) to the heat-receiving body (104). An example of the heat-receiving body (104) is a manifold assembly (917) of the runner system (916).

According to another option, generally speaking, with reference to FIG. 2, the mold-tool system (100) includes (and is not limited to): a body (106) configured to be between a heater assembly (102) and a heat-receiving body (104). The body (106) is formed from a swaging process to facilitate heat transfer such that heat transfer from the heater assembly (102) to the heat-receiving body (104) is improved. A technical effect of the mold-tool system (100), for the case where the body (106) is formed from the swaging process (versus other processes such as brazing), is that the heater assembly and the body (106) may be more easily removable (relative to brazing, for example) because the materials do not adhere to each other. Brazing is a metal-joining process whereby a filler metal is heated above and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting (liquidus) temperature while protected by a suitable atmosphere, usually a flux. The filler metal then flows over the base metal (known as wetting) and is then cooled to join the work pieces together.

With reference to FIG. 2, there is depicted a cross-sectional view of an example of the mold-tool system (100). The mold-tool system (100) may be assembled according to the following method of manufacturing, having steps (A), (B), (C), and (D). Step (A) includes (and is not limited to): swage the body (106) into an intervening space located between the heater assembly (102) and the heat-receiving body (104). Step (B) includes (and is not limited to): drive out air (as much as possible) between the heater assembly (102) and the heat-receiving body (104). Step (C) includes (and is not limited to): work harden the body (106). Step (D) includes (and is not limited to): retain (preferably permanently) the heater assembly (102) in the groove (107) of the body (106). When heated, the body (106) is configured to: (i) expand and drive more air out of a heater-to-manifold interface, (ii) produce higher contact pressures, (iii) conduct heat along a surface of the groove (107) to even out the temperature at the interface between the heater assembly (102) and the heat- receiving body (104). The following are technical benefits for using the method of manufacturing of the mold-tool system (100): (i) increased heat may be transferred from the heater assembly (102) to the heat-receiving body (104), (ii) cooler temperature of the heater assembly (102) during operation of the runner system (916), and/or (iii) improved consistent heat transfer from heater assembly (102) to the heat-receiving body (104).

In accordance with another method of manufacturing the mold-tool system (100), the method includes (and is not limited to): (A) applying the body (106) to the heater assembly (102), (B) placing the body (106) combined with the heater assembly (102) in a groove (107) of the manifold assembly (917) of the runner system (916), and (C) swage the body (106) into the intervening space located between the heater assembly (102) and a surface of the groove (107), so that much of the air is removed from the interface between the heater assembly (102) and the manifold assembly (917). As a result of the method, the body (106) conforms more closely to the surface of the groove (107) and the heater assembly (102), and the body (106) is work hardened so as to retain (preferably permanently) the heater assembly (102) within the groove (107).

It will be appreciated that to provide efficient and uniform heat transfer between the heater assembly (102) and the manifold assembly (917), a swaging process may be used to make the heater assembly (102) conform to the groove (107) defined by the manifold assembly (917). This arrangement reduces (at least in part) the amount of air (which conducts heat poorly) trapped between the heater assembly (102) and the manifold assembly (917). Care should be taken to avoid and/or reduce the possibility of applying the swaging process that may damage the heater assembly (102) thereby decreasing the uniformity of heat transfer and shortening life of the heater assembly (102). Swaging is a process that is used to reduce or increase the diameter of tubes and/or rods (for example). This may be done by placing the tube or rod inside a die that applies compressive force by hammering radially. This can be further expanded by placing a mandrel inside the tube and applying radial compressive forces on the outer diameter. Thus, the inner diameter can be a different shape, for example a hexagon, and the outer is still circular. Swaging is a forging (forming) process in which the dimensions of an item are altered using a die or dies, into which the item is forced. Swaging is usually a cold-working process; however, swaging is sometimes done as a hot-working process. The term swage can apply to the process of swaging, or to a die or tool used for swaging.

In accordance with an example, the body (106) is formed such that the body (106) envelops the heater assembly (102) on at least three sides of a cross section of the heater assembly (102). To accomplish this, the body (106) may have (by way of example) a U-shaped cross section, the outside of which fits in the groove (107) defined by the manifold assembly (917). After forming the body (106), the body (106) is fully annealed (that is, elevated temperature that can be produced through application of heat or by other means) to a dead-soft condition. Alternately, the heater assembly (102) may be fitted snuggly into a tube of the body (106). The body (106) is inserted in the groove (107) defined by the manifold assembly (917), then the heater assembly (102) is inserted in a cavity defined by the body (106). To securely attach or fix the heater assembly (102) to the manifold assembly (917), the body (106) may be swaged; the heater assembly (102) is not swaged. This arrangement reduces the possibility of damage to the heater assembly (102). In a dead-soft condition, swaging causes the body (106) to flow into (at least in part) any irregularities of the heater assembly (102) and the surfaces of the groove (107) more readily and completely in comparison to the heater assembly (102) could form into the groove (107) by itself. As the body (106) hardens, the body (106) securely retains the heater assembly (102) in the groove (107). On the one hand, it will be appreciated that, in accordance with an option, the body (106) is sold separately from the heater assembly (102) and the heat-receiving body (104), and the body (106) is retrofitted to an existing heater assembly (not depicted) and an existing heat- receiving body (not depicted). On the other hand, it will be appreciated that, in accordance with another option, the body (106), the heater assembly (102) and the heat-receiving body (104) are all combined and sold together as a single kit to an end user. According to a specific example, the mold-tool system (100) includes (and is not limited to): (i) a heater assembly (102), (ii) a heat-receiving body (104) configured to receive, at least in part, the heater assembly (102), and (iii) a body (106) positioned (or sandwiched) between the heater assembly (102) and the heat-receiving body (104).

The heat-receiving body (104) may include, for example, a manifold assembly (917) of a runner system (916). The manifold assembly (917) defines a groove (107) configured to receive, at least in part, the heater assembly (102). The body (106) may be called (or may include) a layer and/or a liner (for example). The heater assembly (102), heat-receiving body (104), and the body (106) have coefficient of thermal expansions such that heat transfer from the heater assembly (102) to the heat-receiving body (104) is improved. By way of example: the body (106) includes a copper alloy, and/or the body (106) includes an aluminum alloy. The body (106) has a softness and malleability in an annealed condition. The body (106), which may be called an intermediate layer of material, is positioned or placed between the heater assembly (102) and the groove (107) defined by the manifold assembly (917). The body (106) may be a soft, malleable metal that conducts heat well, such as (by way of example and not limited to) an alloy having copper, aluminum, and/or magnesium, or any functional equivalent thereof. The following represent examples of the coefficients of thermal expansion. Example (a): for the heater assembly (102), an outer sheath of the heater assembly (102) has a coefficient of thermal expansion in the range from 11.2 to 13.8. Example (b): for the heat-receiving body (104), the steel of the manifold assembly (917) has a coefficient of thermal expansion in the range from 11 .2 to 13.8. Example (c): for the case where the body (106) includes a copper, alloy, the body (106) has a coefficient of thermal expansion of 16.8. Example (d): for the case where the body (106) includes an aluminum alloy, the body (106) has a coefficient of thermal expansion of 23.1. The measured unit of the coefficient of thermal expansion expressed above is 10 ⁶ (that is, 10 raised to power of negative 6 or -6) m/m °K (meter per meter degrees Kelvin). It is understood that 1 0 raised to power -6 (negative 6) equals 0.000001 . By way of example, the heater assembly (102) and the steel material of the manifold assembly (917) have similar coefficients of thermal expansion, between 11.2 and 13.8 (respectively). Both copper and aluminum have relatively higher coefficients of thermal expansion, with copper at 16.8 and aluminum at 23.1. Therefore, either material (copper and/or aluminum) may expand on temperature rise more than either the heater assembly (102) and/or the manifold assembly (917). The force generated by the thermal expansion of the body (106) will increase conformance of the body (106) to both the heater assembly (102) and the groove (107) of the manifold assembly (917), and this arrangement further reduces resistance to heat transfer between the heater assembly (102) and the manifold assembly (917).
