An electrode device is provided with a closed part facing a bottom part of a bottomed hole when inserted inside the bottomed hole, and a flow through hole linking the inside and outside of the electrode device is formed in the electrode device. When surface treatment is implemented on the inner wall surface of the bottomed hole, the hollow electrode device is inserted into the inside of the bottomed hole, the electrolytic treatment solution is made to flow through the space inside the bottomed hole, and power is applied across the electrode device and the inner wall surface of the bottomed hole. The closed part faces the bottom part of the bottomed hole as an electrode across a prescribed surface area; therefore, electroplating at the bottom part of the bottomed hole proceeds to the same extent as other sites.

A casting device in which refrigerant is pressure-fed to a cooling passage formed in a die, leakage of refrigerant in the die can be reliably detected in a short time without a significant modification applied to the conventional device. A casting device includes a pressure-feed device that pressure-feeds refrigerant to a cooling passage formed in a die, and a release agent coating applicator that applies a release agent to the die, and further includes a unit that mixes a fluorescent agent into the refrigerant (fluorescent agent tank), a unit that irradiates the die surface of the die with black light while the refrigerant containing the fluorescent agent mixed therein is pressure-fed to the die, and an imaging device that captures an image of the die surface. The imaging device is integrally assembled with the release agent coating applicator.

Method for near-contour surface temperature control of shell-shaped molds (14) with mold rim zones (1), wherein the temperature control of the mold (14) on a near-contour temperature control surface (4) with adjacent, web-like or wall-like separated subareas (4.i) is effected from the respective rear space (3) of the mold rim zones (1) of the mold (14) and/or the respective mold rim zone (1) of the mold (14). The shell-shaped molds (14) are designed in two or more parts with the respective mold rim zones (1). Specifically, the temperature control as cooling in the form of temperature control on the temperature control surface (4) is locally different in subareas (4.i). The temperature control surface (4) is effected in accordance with the temperature ranges of convection, bubble evaporation, partial and/or stable film evaporation of the liquid cooling fluid water.

A mold assembly and method for fabricating an infiltrated drill bit may comprise a mold forming a bottom of the mold assembly, a funnel operatively coupled to the mold, an infiltration chamber defined at least partially by the mold and the funnel to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated drill bit, a displacement core arranged within the infiltration chamber and having one or more legs that extend therefrom, a metal blank arranged about the displacement core within the infiltration chamber, and one or more thermal elements. A method may comprise providing a mold assembly having component parts that include a mold that forms a bottom of the mold assembly and a funnel operatively coupled to the mold, imparting thermal energy to the infiltration chamber with one or more thermal element, and heating contents contained within the infiltration chamber.

An integrated module for a vehicle suspension includes a bearing outer ring and a suspension upright or knuckle, the outer ring being formed of a first high-strength material, and at least part of the suspension upright or knuckle being made from a second, metallic material, the second material being lighter than the first material. The upright or knuckle is co-moulded radially onto the outside of the bearing and is directly fixed to the bearing ring by means of an interface for form coupling. Opposite axial ends of the bearing outer ring are configured to receive closing and sealing devices for protecting one or more races of the bearing outer ring during co-moulding and for removing heat from the races during co-moulding.

A method for die casting a metal alloy in a cavity, implementing a mold comprising an induction heater to heat the molding surfaces of the cavity. The cavity is filled with the metal alloy by injection and preheated to a nominal preheating temperature T1. The metal in the cavity is solidified. The mold is opened and the part is ejected therefrom. The molding surfaces of the cavity are heated by induction while the part is no longer in contact with said surfaces. The molding surfaces of the cavity are sprayed, the mold being opened, by a release agent. The mold is closed and the cavity is heated the temperature T1.

A cooling system (10) for molding fixtures, and particularly for foundry molds, comprising: water treatment means (II)compressed air generation means (12)means (13) for pressurizing the treated watera device (14) for mixing air with the treated water, and for the controlled ejection of atomized water under pressure toward a cooling circuit (16) of a molding fixture.

A water-cooled mold for low-pressure casting of an aluminum alloy wheel includes an upper mold, a lower mold and a side mold which surround a cavity of aluminum alloy, in which a cooling insert is embedded into a side mold frame of the side mold; an upper parting surface, a lower parting surface and a side parting surface of the cooling insert are respectively in contact parting with the side mold frame, the side parting surface includes a front zone and a rear straight zone, and a gap of 1.5-2.5 mm is formed between the rear straight zone and the side mold frame.

When a mold for a tire is manufactured by casting, generation of a casting defect for the casting of the mold is easily suppressed so that the manufacturing efficiency of the mold is improved. The mold molds a tire by molding parts arranged along a tire width direction. A width direction of a casting of the mold corresponding to the tire width direction is matched with a vertical direction. A riser is connected to a part of the rear-face part of the casting located on the rear-face side of the molding part. A chiller is arranged on a part other than the riser of the rear-face part of the casting.

A casting mold for a crankcase of an internal combustion engine includes a water jacket core which has a frame core and a cooling duct core. A land core is provided which is designed and positioned in such a way as to form a cooling duct in an inter-cylinder land of a crankcase. The land core is retained in the frame core and is, or can be, centered using a top core.
