  • Patent number: 9352494
    Abstract: Provided is a molding die including a die body for molding a molded article, which has an undercut, and a demolding core movable to approach and separate from the die body. When the demolding core is separated from the die body, the demolding core elastically deforms the molded article such that the undercut separates from the die body and makes it possible to remove the molded article from the die body. The die body includes a recess where the depth gradually reduces along the direction in which the demolding core separates from the die body. During molding of the molded article, a projection is formed on the undercut in accordance with the shape of the recess. During removal of the molded article, the engagement between the projection and the recess regulates the movement of the molded article in a direction intersecting the movement direction of the demolding core.

  • Patent number: 8651449
    Abstract: Concrete forming panels according to the present invention are formed using a series of interlocking panel sections mechanically connected at a forward face of the panel. The mechanical connection uses a hook portion of one section received in a slot portion of an adjacent section with a pivot and stop relation defining the planar forming face. A series of brace members extend across the panel sections on a rear surface and maintain engagement of the panel sections and reinforce the panel sections against deformation of the forming face during use of the panel. The arrangement is economical to manufacture in many different sizes as may be required by a customer. Some welding is used, however the mechanical connection greatly reduces the amount of welding required. Replacement sections can easily be used to repair damaged panels.

  • Publication number: 20030089836
    Abstract: The present invention provides a device for suspending a loaf of bread dough throughout the final rise step and for subsequent transfer to the baking location by gently rolling the loaf from the device without having to manually handle the dough, thus preserving the rise and the shape of the loaf. The present invention has two end support structures that are attached by removable lateral supports. The loaf support components include a fabric web and two rigid longitudinal members. The ends of the longitudinal members are then placed between the end supports in contact with top edge of the end supports. As a result, the fabric web is therefore supported along two edges between the end supports and is suspended over the work surface forming a downwardly depending u-shaped pocket. The loaves of bread dough are placed individually into the fabric pockets and are supported in a uniform manner transferring pressure along the entire bottom and critical side surfaces of the rising bread loaf.

  • Patent number: 6176464
    Abstract: A snowman mold having a base member and a torso member defining interior spaces for receiving snow therein. The mold members include annular flanges extending radially outwardly from the members in a configuration that allows the torso member to be stacked upon and releasably secured to the base member prior to filling with snow. While the base and torso members have a substantially similar configuration, the torso member presents a circumference dimension that is smaller than the circumference dimension of the base member such that the torso member fits within the base member in a storage configuration. A snowman is constructed using the present invention by placing the base member on a surface, stacking and securing successively smaller mold members thereon, and depositing snow into the opening in the uppermost member. When the mold is completely filled, the members may be successively removed by opening the doors of each member and releasing the fasteners coupling the members together.
