摘要： A molding apparatus and method of use thereof. The molding apparatus has a stationary mold base, and at least one moveable mold core rotatable into and out of a facing relationship with the stationary mold base. When the moveable mold core is in its closed position, it cooperates with the stationary mold base to define a mold cavity. The mold base may be shaped so as to aid in forming a part, or to hold a sheet of material onto which molding material is to be deposited so as to encapsulate the part on one or more edges or surface regions. Structure may also be encapsulated onto the surface of the material during the molding operation.

摘要： A mold press for an electric drive arrangement for controlling opening and closing press movement. The drive arrangement includes a pair of generally identical drive units connected between upper and lower press plates. The drive units in a preferred embodiment each employ a ball-screw arrangement. A screw shaft extends vertically of the press, and engages a ball nut assembly which is mounted on the top press plate for effecting movement thereof toward and away from the bottom press plate. An electric motor is coupled to the screw shafts for effecting high speed opening and closing movement of the top press plate. A force apply device, such as an inflatable hose or bladder, is associated with the bottom press plate to effect application of the desired press closing force. A control linkage is connected between the top press plate and the frame for effecting automatic sideward swinging of the top press plate between a side access position when the plate is in its fully opened position, and an operational position wherein the top press plate is disposed vertically aligned above but spaced upwardly from the lower press plate. The swinging movement of the top press plate between these two positions is effected automatically in response to vertical displacement of the top press plate by the main drive unit during an upper portion of the normal opening and closing movement of the top press plate. This control linkage, in a preferred embodiment, comprises a self-contained extendible spring device such as an air spring which effectively assumes a minimum height position when the top press plate is intermediate its stroke so as to induce sideward swinging of the top press plate during the upper portion of the stroke.

摘要： An apparatus for forming objects from a moldable material such as wax. The apparatus includes upper and lower mold pieces having upper and lower mold cavity halves attached thereto. A lever arm extends from the upper mold piece and is pivotally attached to a linear actuator. The upper and lower mold pieces are pivotably connected to one another. Movement of the linear actuator results in opening and closing of the upper and lower mold cavity halves about the pivotable connection of the upper and lower mold pieces.

摘要： A clamp for holding together the portions of a mold used in molding solid objects from a reacting liquid such as polyurethane has a C-shaped frame which is pivotally mounted on a pedestal to swing through an arc. The C-shaped frame of the clamp consists of an integral structure having an upper jaw connected by a column to a lower jaw. The frame supports a bed, crown and platen. The bed and crown are each a plate-like member that is mounted to pivot relative to one of the jaws. The platen is mounted preferably on the bed or lower one of such members. The mold portions are mounted on the crown and platen with the parts being arranged to move so that the mold portion engage and disengage. The invention also includes a method of molding wherein the mold portions are engaged and disengaged by a process that involves pivoting at least one and preferably both of the portions relative to the C-shaped frame.

摘要： A closing device for a mold group with two half-molds extends along a main axis and has a device body mountable to one of the two half-molds, and a closing group having a closing element rotatable about a rotation axis between a closing position, in which the two half-molds are lockable and an opening position, in which the two half-molds are releasable. A movement group housed in the device body and engaged with the closing group to rotationally move the closing element has a stem movable along the main axis and transmission members for transforming linear motion of the stem into rotatory motion of the closing element. A command group has a command plate engaged with one command end of the stem and a metal sealing bellows engaged with the command plate. A position of the metal sealing bellows corresponds to an axial position of the command plate and of the stem.

摘要： Mold compound transfer systems and methods for making mold compound transfer systems are disclosed herein. A method configured in accordance with a particular embodiment includes placing a sheet mold compound in a containment area defined by a tray cover, and dispensing a granular mold compound over the sheet mold compound. The sheet mold compound can have a first density and the overall granular mold compound can have a second density less than the first density. The method further comprises transferring the solid sheet carrying the dispensed grains to a molding machine without using a release film.
