Mold Having Movable Core Or Movable Pin Patents (Class 425/577)
  • Patent number: 10899053
    Abstract: A process is provided for making a walled structure using an injection molding apparatus. The apparatus has a molding space formed between a mold cavity and an inner core disposed within the mold cavity. The molding space defines a shape of the structure. The process includes injecting molding material into the molding space, moving or retaining a portion of a movable impression member protruding from the inner core within a portion of the molding space so as to create a recess within an inner wall of the structure, and retracting the impression member into the inner core such that the impression member is cleared from the molding space. Precision control in forming the impression member is provided by a closed-loop configuration using a sensor that measures a molding space parameter (e.g., temperature), optionally in combination with a servo drive for activating the impression member.

    Abstract: Thus far, it has not been possible to produce laryngeal masks having a supraglottic tube as a one-piece unit. If the supraglottic tube (2) is provided with three lumens (4, 5, 6), the center one (6) of which has no passage to the respiration room (10), the invention provides a solution. The invention proposes that the center guide lumen is provided with a longitudinal slit (8) extending from the distal end (9) to the laryngeal mask head (3). Thus, a connecting web can be attached between the two cores or sliders forming the lumens, generating the desired stability in order to maintain the pressing power tool state without deformation.

  • Patent number: 9028737
    Abstract: Provided is a technology with which, when producing a resin molded article, the inside of which is provided with an insert component such as a terminal fitting, it is possible to prevent the insert component from being exposed at an inappropriate position, and to ensure the desired positional accuracy. In an injection molding device, the accuracy of the position of a terminal is improved by allowing a core-back mold to move after a terminal, which is an insert component, has been inserted in a terminal tip holding section of a slide mold. By allowing the core-back mold to move by only a prescribed amount prior to injection molding, a resin wall is formed between the core-back mold and the terminal. The inappropriate exposure and shorting of and the adhesion of foreign substances to, and the like, the terminal can thus be prevented.

  • Patent number: 8905745
    Abstract: A mold core includes first and second main bodies and an adjustment assembly. The first main body includes a front surface, a rear surface opposite to the front surface, and a receiving cavity passing through the front and rear surfaces. The front surface defines two first cavities at opposite sides of the receiving cavity. A connection line of centers of the first cavities intersects with a symmetry axis of the first cavities to form a first intersection point. The second main body includes a forming surface defining second cavities. A connection line of centers of the molding cavities intersects with a symmetry axis of the second cavities to form a second intersection point. The forming surface is coplanar with the front surface. The adjustment assembly abuts the first and the second main bodies to compensate an offset between the first and second intersection points to satisfy a predetermined range.

    Abstract: The first sliding molds are movable back and forth in a direction orthogonal to a back-and-forth direction of the movable mold, come into contact with a periphery of the central mold when the first sliding molds move forward to form a first cavity for molding a panel body, and avoid interference with a second sliding mold when the first sliding molds move back to form a second cavity for molding a frame. The second sliding mold is movable back and forth in the back-and-forth direction of the movable mold, allows a forward movement of the first sliding molds when the second sliding mold moves back to form the first cavity, and comes into contact with an inner peripheral edge and an outer peripheral edge of the panel body held on a fixed mold, thereby forming sealing portions, when second sliding mold moves forward to form the second cavity.

    Abstract: A mold and a method for producing two-color injection-molded parts involves simultaneous injection of two kinds of molding material, in which a pressure difference between two kinds of molding materials is induced so that one of the molding materials is infiltrated into and bonded to the other molding material during solidification. The method for producing two-color injection-molded parts may include simultaneously injecting a first material and a second material to a first gate and a second gate to be filled in a first cavity and a second cavity, and closing the second gate such that the first molding material, which is not solidified, pushes a slide mold provided between a first mold block and a second mold block using a holing pressure of the first gate and is infiltrated into an unsolidified layer of the second molding material and solidified.
