Description

COMPONENT OF METAL MOLDING SYSTEM

TECHNICAL FIELD

The present invention generally relates to, but is not limited to, molding systems, and more specifically the present invention relates to, but is not limited to, (i) a component of a molding system, (ii) a molding system having a component, and/or (iii) a method, etc.

BACKGROUND OF THE INVENTION

Examples of known molding systems are (amongst others): (i) the HyPET™ Molding System, (ii) the Quadloc™ Molding System, (iii) the Hylectric™ Molding System, and (iv) the HyMet™ Molding System, all manufactured by Husky Injection Molding Systems Limited (Location: Bolton, Ontario, Canada; www.husky.ca).

Generally, the processing (handling) of a molten metallic molding material imposes challenges on materials used in components of known metal molding systems, such as: (i) high heat that causes reduction in mechanical properties (of components of the molding system, etc), and/or (ii) corrosive attack by the molten molding material on the components of the metal molding system. It is generally known to use a combination of two or more layers in a barrel (generally known as a conduit or the component of the metal molding system). More specifically, known barrels for molding systems configured for processing magnesium alloys, etc, have a body that includes two materials: (i) an Inconel 718 outer shell that provides high-temperature strength and creep resistance, and (ii) a Stellite 12 inner liner that provides corrosion resistance and wear resistance.

United States Patent Number 4,089,466 (Inventor: Lomax et al; Published: 5/16/1978) discloses a lining alloy for bimetallic cylinders; more specifically, this patent appears to disclose a wear and corrosion resistant alloy for lining cylinders used in extrusion and injection molding machines comprises tantalum carbide admixed with a nickel-cobalt base alloy. The cylinder lining is preferably prepared by placing a quantity of the alloy in the cylinder and capping the ends of the cylinder. The cylinder is then heated above the melting point of the alloy and spun at a high rate of speed to centrifugally coat the inner surface of the cylinder. The cylinder's end caps are then removed and the lining finished to the correct internal diameter and finish by conventional lathe and hone means. The tantalum carbide added to the base alloy has an affinity for carbon and tends to reduce the free carbon in the final matrix producing a lining which has desirable hardness and corrosion resistance throughout the thickness of the lining. United States Patent Number 4,399,198 (Inventor: Lomax et al; Published: 8/16/1983) discloses a lining alloy for bimetallic cylinders; more specifically, this patent appears to disclose a wear and corrosion resistant alloy for lining cylinders used in extrusion and injection molding machines comprises at least two carbides admixed with a nickel-cobalt base alloy. The cylinder lining is preferably prepared by placing a quantity of the alloy in the cylinder and capping the ends of the cylinder. The cylinder is then heated above the melting point of the alloy and spun at a high rate of speed to centrifugally coat the inner surface of the cylinder. The cylinder's end caps are then removed and the lining finished to the correct internal diameter and finish by conventional lathe and hone means. The carbide mixture is evenly dispersed in the lining and produces a lining having desirable hardness and corrosion resistance throughout the thickness of the lining.

United States patent Number 4,863,661 (Inventor: Maddy; Published: 9/9/1989) discloses a resin molding process employing a nickel-based alloy liner; more specifically, this patent appears to disclose a method of producing cylindrical objects with one or more lobes in which the bore surfaces are completely protected by a surface layer of abrasion resistant and/or corrosion resistant alloy and which protective layer is free of any contamination by the metal of the substrate. A hard, wear resistant, and corrosion resistant nickel-based alloy is especially suitable as lining material for surface of cylindrical products, such as housings or shells used in extrusion and injection molding devices for processing halogenated resins or rubbers. The alloys will preferably also contain 0.5 to 5% silicon and 1 to 4% boron. Also disclosed is a method of producing cylindrical objects with one or more lobes in which the bore surfaces are completely protected by a surface layer of abrasion resistant and/or corrosion resistant alloy, such as the above-described metal-based alloy.

United States Patent Number 5,711,366 (Inventor: Mihelich et al; Published: 01/27/1998) discloses processing corrosive molten or semi-molten metallic material in an apparatus having contact surfaces of niobium-based alloy; more specifically, this patent appears to disclose an apparatus for processing materials which are highly corrosive while in a thixotropic state (for example, aluminum). The apparatus includes a barrel which is adapted to receive the material through an inlet. In the barrel, the material is heated and subjected to shearing, forming a highly corrosive, semi-solid slurry which is discharged from the barrel through a nozzle. The barrel is constructed with an outer layer of a first material and an inner layer of a Nb-based alloy which is bonded to the outer layer. Positioned within the passageway of the barrel is a screw, the rotation of which operates to subject the material to shearing and move the material through the barrel. The screw is constructed with an outer layer of the Nb-based alloy that is molecularly bonded to an inner core of a different material. The Nb-based alloy is resistant to the corrosive effects of the material being processed.

An abrasion resistant layer is formed in at least portions of the surfaces of the pair of cylindrical bores extending in the vicinity of at least one of the two lines of intersection of the pair of partly overlapping cylindrical bores. The abrasion resistance of the abrasion resistant layer has a maximum in a portion thereof around the line of intersection of the pair of cylindrical bores and decreases gradually with distance from the line of intersection. The abrasion resistant layer is formed by depositing a material containing a hard substance by build-up welding, and the hard substance content of the material in the abrasion resistant layer is varied with distance from the line of intersection. The abrasion resistant layer is formed by depositing a material consisting of a corrosion resistant base alloy and a hard substance. The abrasion resistant layer may be formed on a corrosion resistant layer formed over the entire surfaces of the pair of cylindrical bores.

These other things may include: (iii) a mold break force actuator (not depicted) coupled to the tie bars and used to generate a mold break force that is transmitted to the platens 26, 28 via the tie bars (so as to break apart the mold 21 once the molded article 54 has been molded in the mold 21), and/or (iv) a platen stroking actuator (not depicted) coupled to the movable platen 28 and is used to move the movable platen 28 away from the stationary platen 26 so that the molded article 54 may be removed from the mold 21, and (vi) hydraulic and/or electrical control equipment, etc.

FIG. 2 is a schematic representation of a molding-material handling component of a metal molding system according to a second exemplary embodiment. The component body 9 includes, at least in part, a hot runner nozzle 32 (which is an example of a hot-runner component) of a hot runner 30. The alloy of the component 8 is used in hardened and tempered state. To provide sufficient wear resistance at high temperatures, various surface treatments may be applied.
