摘要： A die casting insert for producing die casted metal parts from liquid metal. The die casting insert has an outer casing shaped to be fixed in the die block of the die casting apparatus. The die casting insert also has a stopper with a purge opening that is adapted to evacuate contaminants topping the liquid metal as pressure is applied to the liquid metal. The stopper, fitted to mate with the hollow inner cavity of the injection sleeve, is constructed to seal the hollow inner cavity of the injection sleeve except at the purge opening when in a first position; and to permit the flow of the liquid metal into at least one molding cavity when the stopper is in a second position. The die casting insert also has an activation mechanism configured to shift the stopper between the first position and the second position.

摘要： A method for removing a part from a mold and to a machine for molding the part, the part made of a material having a glass-transition temperature and a melting temperature that is higher than the glass-transition temperature, and which is shaped in the cavity of a mold, includes at least two mold portions defining the shaping cavity therebetween. The mold is at a temperature between the glass-transition temperature and the melting temperature. The method includes opening the mold by spacing apart the mold portions, locally spraying a cooling gas toward the part remaining in a portion of the mold using at least one nozzle, and, after a predetermined time period following the start of spraying the gas, ejecting the part from the portion of the mold, the time period being such that the part reaches a temperature that is lower than the glass-transition temperature thereof.

摘要： A die casting method and apparatus are provided, thereby making it possible to produce a thin diecast product that has hitherto been considered impossible to realize, and a diecast product is also provided. A semi-solidified metallic material is formed having particles in solid phase of a particle size less than 30 μm, and is thereupon injected into a die. A die casting machine has a sleeve into which a melt of metallic material is poured, and the semi-solidifying material there when it has a certain proportion of solid phase reached is injected into the die with a plunger to which pressure is applied. The melt of metallic material is poured into the sleeve so that the material occupies inside the sleeve at a proportion in vertical cross-sectional area of 30% or less. The particle size in this semi-solid material is held unvaried in a product as diecast.

摘要： A hinge pillar assembly includes a hinge pillar panel that is cast from a die casting process, and that defines an interior surface. An acoustic foam layer is disposed adjacent the interior surface of the hinge pillar panel. An inner retainer panel is attached to the hinge pillar panel. The inner retainer panel secures the acoustic foam layer between the inner retainer panel and the hinge pillar panel. The hinge pillar assembly is cast to define a cored boss that is used to retain the hinge pillar panel within an upper ejector half of a die set during the casting process. A fastener is disposed in the threaded engagement with the cored boss to attach the inner retainer panel to the hinge pillar panel. A vehicle component may be attached to the inner retainer panel.

摘要： Various embodiments provide apparatus and methods for injection molding. In one embodiment, a constraining plunger may be configured in-line with an injection plunger to transfer a molten material from a melt zone and into a mold. The constraining and injection plungers are configured to constrain the molten material there-between while moving. The constrained molten material can be controlled to have an optimum surface area to volume ratio to provide minimized heat loss during the injection molding process. The system can be configured in a longitudinal direction (e.g., horizontally) for movement between the melt zone and mold along a longitudinal axis. A molded bulk amorphous object can be ejected from the mold.
