    摘要: A flexible mold defining either a full base or a quadrant base of a dental model includes a perimeter member for defining the side walls of the base and a shelf extending inwardly from the rear side wall for delineating a slot at the rear of the base, which slot is useable for indexing an arm of an articulator to be attached to opposed ones of the bases. A variant of the mold permits the formation of a pedestal for supporting a matching tooth die. A method of removing the molded article from the mold is also disclosed and claimed.

    摘要: Apparatus for extracting frozen stick confections from several mold cups of a mold strip of a stick confection freezing apparatus is disclosed. At a pre-extraction station, the sticks of the frozen confections are individually grasped and individually pulled with separate spring forces while the mold cups are heated from below by hot water sprays. Each confection is lifted from the mold cup as soon as the surface layer thereof sufficiently thaws, and before each confection is completely removed from the cup, it is released and dropped back into the cup. At a second extraction station, all of the confections are simultaneously removed and thereafter conveyed to apparatus for wrapping the frozen confections.

    摘要: A pair of mating mold halves are mounted between upper and lower clamp plates 25, 22. The lower clamp plate is driven by a hydraulic unit 17 mounted to a base plate 16, which is rotatably disposed on a tiltable table plate 7. The upper clamp plate is journaled between the arms 26, 28 of a yoke pivotally mounted on the base plate and controlled by hydraulic units 29 coupled between the yoke arms and the upper clamp plate. This compact multi-pivotal arrangement affords a large separation stroke between the two clamp plates without, by reason of the lateral pivoting of the yoke and upper clamp plate, requiring any additional overhead or ceiling clearance space.

    摘要: Mold for injection molding battery containers which include a plurality of thin resilient ribs integral with and projecting at acute angles from the inside walls thereof into the cell compartment(s) to hold the battery's innards therein. The core of the mold includes a mandrel defining the cell compartment. The mandrel has dovetail-like mortises therein and complementary-shaped ejector bars reciprocally slideable within the mortises between retracted and extended positions to facilitate stripping the container from the core. The rib-forming portion of the mold cavity is formed in the side walls of the ejector bar. The ejector bars travel with the container during at least part of the ejection cycle so as to free the rib from the rib-forming cavity without untoward resistance or permanent deformation of the ribs.

    摘要: A plastics gutter fitting (8, 11) has at least one transverse groove (10,17) receiving a sealing strip (16) and an inwardly turned clipping nib (9,15) extending across at least one end of a said transverse groove (10,17). The fitting is molded using a three part core of which two outer parts (4,4') can be moved convergently relative to a central part (3) for releasing a molding (8) therefrom. This molding method enables the reentrant where a clipping nib (9,15) extends across an end of a transverse groove (10,17) to be molded integrally in the fitting.

    摘要: A method for axially extracting a rubber hose of great length from the correspondingly long core about which the article has been formed and vulcanized, comprising the steps of positioning the article having its core therein on a correspondingly long longitudinally displaceable support having an upper surface adapted for frictionally engaging the hose, securing one end portion of the core, external to the hose, in a stationary location, and longitudinally displacing the support for spacing the same from said location, whereby a pull is exerted at all points along the hose for causing the core to be extracted from the hose.

    摘要: A method and apparatus are disclosed for injection molding tubular plastic articles around cylindrical core pins at a molding station, for cooling the articles while supported on the core pins, and for then axially stripping the articles from the core pins at an ejection station. The article stripping step is accomplished by a horizontally reciprocable carriage which is selectively moved into and out of vertical alignment with a set of core pins and molded articles positioned at the ejection station. Sectional gripping members on the carriage are radially closable when in alignment with the molded articles, to grasp the articles for their axial removal from the core pins upon the horizontal displacement of the carriage. The stripped articles may be held in a horizontal cantilever position between the gripping members during an operational dwell time for additional cooling subsequent to their removal from the core pins.
