Patent number: 5702733Abstract: A press working machine includes base members having concave portions, slider members arranged in the concave portions, link arms attached to first ends of the slider members respectively, and cylinders attached to the arms, for bending and extending the same. Furthermore, press members having curved mold-facing surfaces are arranged on the slider members. Molds having deformable structures are arranged on the press members. A workpiece is inserted between the molds, to be press-worked. The slider members are actuatable to press the press members against the molds, so as to deform the molds into different mold shapes. Thus, it is possible to press-mold workpieces into a plurality of shapes with a single mold assembly, thereby reducing the cost for manufacturing the mold assembly, omitting an operation of exchanging the mold assembly, and reducing the manufacturing cost.Type: GrantFiled: April 9, 1996Date of Patent: December 30, 1997Assignee: Enami Seiki Mfg. Co., Ltd.Inventor: Toshiaki Enami

Patent number: 5637330Abstract: The invention relates to an apparatus for making hard sided luggage shells and other containers by vacuum forming or pressure forming thermoplastics. An apparatus for making shells and containers with integrally molded frames is disclosed. An apparatus for manufacturing differential pressure formed containers with framed openings, without the need for later attachment of a separate frame element to the molded shell. An apparatus also is disclosed for reducing the undesirable stretching of shell material that occurs during differential pressure forming, particularly the thinning of corner portions of the shell or container. The apparatus of the invention more efficiently utilizes the thermoplastic material by moving material from otherwise offal portions into the molded product. An improved device for severing the offal material from the final product is disclosed.Type: GrantFiled: June 7, 1995Date of Patent: June 10, 1997Assignee: Samsonite CorporationInventors: Elliot Younessian, Joseph Kapushion, Robert L.

Patent number: 5595769Abstract: The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container. The lid latching mechanism features a large, trapezoidally-shaped opening hole. The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process. The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member. The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.Type: GrantFiled: June 7, 1995Date of Patent: January 21, 1997Assignee: Tenneco PackagingInventors: Glenn C.
