  • Patent number: 9011137
    Abstract: A mold and method for making a hollow core concrete block. The mold has two opposing side walls; a bottom wall; a front wall; a top side with an opening through which the block can be removed from the mold; a cover, and a rear side through which liquid, such as concrete, can be poured into the mold. Extending from the two side walls are a pair of trunnions about which the mold is rotatable, such that when the mold is suspended by the trunnions and the mold is empty, gravity rotates the mold from a block-removal orientation in which the top side faces upwards to a mold-filling orientation in which the rear side faces upwards. The trunnions are also positioned such that when the mold is filled with the liquid, gravity rotates the mold from the mold-filling orientation to the block-removal orientation.

    Abstract: In a method for transcripting fine patterns and an apparatus for transcripting fine patterns, the ingress of bubbles is prevented and patterns are transcripted with a high throughput by a relatively compact apparatus. For this purpose, a back surface of a stamper is vacuum sucked and the stamper is brought into close contact with a target of transcription with its surfaces coated with resist and pressure is applied thereto. At this time, the stamper is deformed into a spherical shape or bent to expand the close contact face from a central area to a peripheral area to prevent the ingress of air bubbles into between the target of transcription and the stamper.

  • Patent number: 8323715
    Abstract: The complementary parts of food products destined to be coupled together are located on the frontal surfaces of half-moulds travelling on two different loop conveyor lines. The first conveyor line extends, at least partially, above the second, so to be included within the surface area occupied by the second line itself. Spatial occupation is further reduced since, downstream to the coupling station, the coupled half-moulds travel with the same spacing step that they had before coupling, with additional advantages in terms of energy absorption and advancing velocity in a successive thermal conditioning station, such as a refrigerating tunnel. One of the half-moulds can be removed upstream to the thermal conditioning station, resulting in an additional reduction in energy absorption since needless subjecting of the half-mould to the thermal cycle to which the products are subjected is avoided.

  • Publication number: 20110045119
    Abstract: An exemplary mold includes a core plate receiving a core insert, a cavity plate receiving a cavity insert, and an ejection mechanism for ejecting the core insert. The core insert defines a first molding surface, and the cavity insert defines a second molding surface cooperating with the first molding surface. The ejection mechanism includes a top plate, a bottom plate, and an ejection member fixed to the top plate. The ejection member includes an ejection rod and an ejection head. The ejection rod includes a first rod, and a first engaging body forming a protrusion facing toward the first rod. The ejection head includes a second rod, a second engaging body defining a recess facing toward the second rod, and an ejection portion engaged with the core insert. The protrusion is movably engaged in the recess, so that if the ejection rod goes off-axis, the core insert can stay on-axis.

  • Patent number: 7862325
    Abstract: A die for forming a lost wax ceramic core allows the formation of non-parallel separating spaces between adjacent portions of the core. The core will eventually form cooling channels in an airfoil. The die for forming the core includes a plurality of moving parts having rib extensions. At least some rib extensions are non-parallel to form the non-parallel spaces. The die includes two main die halves that come together to form several of the spaces. Inserts move with those die components and come together to form other spaces. At least one of the inserts contacts surfaces on one of the die halves, such that the non-parallel spaces are formed.

  • Patent number: 7798807
    Abstract: The present invention relates to plastic injection molding tool, having a front and a rear tool half which, in the closed state, delimit a hollow molding chamber between them. The rear tool half has at least one ejector and at least one oblique slide. The ejector is constituted by at least one front part, designed as a driver, of the rear tool half. It can be displaced to a limited extent by a linear drive mechanism, which is supported on another portion of this tool half or on the base thereof. It is furthermore connected on its rear via a transverse guide element, extending at a defined angle in regard to the movement direction of the linear drive mechanism, with the oblique slide, which is guided by an oblique guide element on a part of the rear tool half which is fastened on the base.

  • Publication number: 20100221379
    Abstract: An ejector apparatus moves a lift core extending through a core of a component of a resin molding mold to form an undercut portion in a molded piece and is installed so as to be capable of moving obliquely with respect to the core surface in a longitudinal direction. An ejector plate is arranged between the core and a base plate below the core, so as to be capable of moving up and down. A slide path is formed in the ejector plate extending in a direction in which a lower end of the lift core makes relative horizontal movement during ascent and descent of the lift core. A slide base is movably arranged in the slide path and coupled to the lower end of the lift core. A guide rod imparts a moving force within the slide path to the lower end of the lift core during ascent and descent of the ejector plate.

  • Patent number: 7695270
    Abstract: A mould is provided for the injection molding of a plastic piece that includes at least two adjacent parts of two compatible plastic materials, assembled to one another by welding or gluing, of different types and/or colors. The mould includes a mould cavity defined by at least two non-planar walls and at least one retractable wall movable between extended and retracted positions, dividing the mould cavity into at least two compartments supplied separately with plastic. When extended, a non-linear edge of the retractable wall cooperates with a wall of the mould cavity in a play-free manner.

  • Patent number: 7661947
    Abstract: A molding apparatus is configured with a distribution channel configured to deliver a blended feed composition directly into an article molding region such that a molded article is formed with gating on the bottom surface of the article. The article molding regions are formed into front sides of opposed “A” and “B” surface mold tools that, when moved into a mating relationship with one another, form closed molding cavities within which molded articles are generated from molding material feed. The article molding regions each generally have a body bounded by a perimeter that establishes an outer edge for an article molded in the one of the closed molding cavities. Additionally, the body of each article molding region of the “A” surface mold tool is adapted for molding a bottom surface for the composite article, and the body of the article molding region of the “B” surface mold tool is adapted for molding a top surface for the composite article.
