  • Patent number: 7984626
    Abstract: In the initial stage of die-opening operation when an upper core 3 moves upward together with an upper die plate 1, an upper cavity die 2 is biased downwardly by an elastic member 10 so as to press the lower surface of the upper cavity die 2 against the upper surface of a lower cavity die 6 and keep their contact, thereby forcing a molded glass element 4 to remain on a lower core 5 by utilizing the difference in outside diameter between the lower core 5 and the upper core 3. This makes it possible to securely release the molded glass element 4 from the upper core 3 and leave the molded product on the lower core 5 upon die opening, enabling smooth removal and automated transportation of the molded product.

  • Patent number: 6223561
    Abstract: A press mold for glass substrate includes an upper mold and a lower mold, and a pressure apparatus for applying pressure to the upper mold and the lower mold, for molding a plate-shaped glass substrate having a predetermined thickness between the upper mold and the lower mold. An engaging projected piece is projectingly provided on the side portion of the upper mold, an engaging projected piece supporting portion for supporting the engaging projected piece is provided on the side portion of the lower mold, and an end portion of the upper mold is formed so as to be released from the lower mold with the engaging projected piece as a rotating shaft. Variance in pressure on mold surfaces between the upper mold and lower mold is detected, and a buffer made of material having lower compressive yield strength than material constituting the lower mold is inserted between the lower mold and the pressure apparatus in a position corresponding to the mold surface portion at lower pressure.

  • Patent number: 6173587
    Abstract: A mold assembly (34) for cyclically forming heated glass sheets includes a lower mold (36) having an upwardly oriented mold face (356) and an upper mold face having a downwardly oriented mold face (56) that opposes the upwardly oriented mold face of the lower mold to form a heated glass sheet during movement of the molds toward each other. Alignment guides (122,124) align the molds (36,38) with each other as necessary during movement of the molds toward each other. Detachable connectors (362) detachably connect the molds to each other for installation and are disconnectable to permit the molds to be used for glass sheet forming. In one embodiment, the detachable connectors (362) are latches that include a latch member (364) and a keeper (366), and in another embodiment the detachable connectors are retainers (370) engageable and disengageable from the molds to provide their detachable securement.

  • Patent number: 6109063
    Abstract: A mold opening and closing mechanism for a section of an I.S. machine includes a mold carrier assembly and horizontal axially extending shafts. A housing supports these shafts for axial displacement and includes first and second vertically extending ducts which terminate at their tops with a sleeve. A manifold assembly includes a manifold including a plenum which overlies each of the mold halves. A spacer secured beneath said frame and having vertically extending holes communicates with the downwardly opening exit of the plenum for delivering cooling air from the plenum to the vertical cooling air passages of the mold halves. The manifold includes a pair of horizontally extending cylindrical inlet holes A pair of cylindrical tubes are received by the cylindrical holes and first and second elbows connect a second end of each of the cylindrical tubes to the sleeves so that cooling air from the ducts will be delivered to the pair of tubes.

  • Patent number: 6085552
    Abstract: A mold opening and closing mechanism includes an aligning mechanism which has a horizontal mounting plate including a number of vertical openings for the number of molds, that is supported by a pair of spaced vertical uprights secured to the section frame top surface. A plurality of aligning cylinders are located in the vertical openings in the horizontal mounting plate and move parallel with the mold holder motion. Each cylinder includes surfaces configured to mate with the clamping surfaces of the mold holders. The axis of one of the aligning cylinders is held but not clamped at the theoretical centerline so it can move to the actual centerline when the mold holders are located at the advanced clamped closed position.
