An undercut processing mechanism includes: a core pin for forming an inner circumferential surface of a tubular projection; a slide core for forming an outer circumferential surface of the tubular projection; a sliding piece for causing the core pin to advance/retract in an axial direction of the tubular projection; a retaining piece for causing the sliding piece to advance/retract; a holder for accommodating the retaining piece such that the retaining piece can advance/retract; and a movement amount restrictor for restricting a movement amount of the core pin. The retaining piece is operable to advance/retract in a state where a stationary die and a movable die are closed. When the core pin retracts in conjunction with retraction of the retaining piece and a movement amount of the core pin reaches a restricted distance, the core pin and the slide core retract together, thereby allowing an undercut portion to be demolded.

The present invention relates to a mould assembly (100) for manufacturing a wind turbine blade shell part, and to a method of manufacturing a wind turbine blade shell part using the mould assembly (100). The mould assembly (100) comprises a lowering device (85), which is adapted to carry and lower a root end insert onto the moulding surface of the mould, the lowering device (85) being attached to the mould and comprising a frame (86) for carrying the root end insert. Two synchronized hydraulic cylinders (91, 92) are used as driving means for lowering the frame, each hydraulic cylinder comprising a piston chamber and a rod chamber, wherein the piston chamber and the rod chamber of each cylinder are connected to each other via a respective valve assembly (110) comprising a fluid line (96) and a valve (97).

The invention relates to a spherical receiving device for receiving at least one rotational mold, which is configured and intended to be driven to rotate in a rotational device by means of a drive wheel rolling on the outer side of the spherical receiving device. The spherical receiving device is distinguished by the fact that it has at least one guiding device which causes a drive wheel rolling on the outer side of the spherical receiving device to follow a predetermined rolling path on the outer side of the spherical receiving device. The invention also relates to a rotational device which has such a spherical receiving device and a drive wheel which is driven by means of a drive motor, said drive wheel rolling on the outer side of the spherical receiving device and driving the spherical receiving device to rotate.

A reusable countertop mold in accordance with the present invention includes at least one mold sheet, but generally a plurality of mold sheets are required to extend about a predetermined portion of a periphery of a floor mounted cabinet. The mold sheet is dimensioned and configured to ultimately form a countertop having a predetermined configuration with predetermined dimensions. The mold sheet includes a relatively thin base portion and a wall portion perpendicular to the base portion. The reusable countertop mold further includes a plurality of fastener recesses in an inner side portion of the base portion, the recesses ultimately allowing fasteners to pass through a countertop substrate and into the floor mounted cabinet, after the base portion has been inserted between the countertop substrate and the cabinet. After a countertop forming material has hardened upon the countertop substrate and the mold sheet, the base portion of the mold sheet is slidably removed from between the countertop substrate and the cabinet, thereby allowing the reusable countertop mold to be reused for another countertop forming project.

A method of moulding (10; 20) and apparatus (108; 208; 308) therefor, in which a workpiece (100) is preheated and/or post-cooled before and/or after a moulding process, allowing optimal use of the tool for high precision moulding operations.

A display system includes: an imaging unit that images a mold from below; and a display unit that displays an image taken by the imaging unit together with a carry-in range of the mold in order to transport the mold in place between the stationary platen and the moving platen.

An assembly for use with a glove manufacturing system is provided. There may be an assembly having first and second holders that engage a glove mold. The first and second holders have respective ledges that each engage respective first and second sides of an edge that defines a slot in the glove mold. With the first and second holders coupled to the glove mold, a connector can connect the first and second holders to a support structure to thereby couple the glove mold the support structure. Then, the gloves may be formed through the use of the glove mold.

A rapid mold replacing device for use in molding machine includes: a mold having lateral walls at two ends disposed with a pair of bolt slots; a pair of fastening members, having a locking member connected at an outer side of each fastening member, and protruded with a locking bolt, and a top surface of each locking member having an unlocking slot; and an unlocking mechanism, disposed on a top surface of the elevation seat and having at least one first retractable driving device, and a pair of unlocking blades capable of being synchronously driven by the first retractable driving device; when the pair of unlocking blades are inserted in or released from the pair of unlocking slots, the mold can be formed in an un locked or a locked status to the mold.

A leveler table includes a plate with a flat top work surface that is level in all planes, by locating a circular level recessed within the center of the plate, so that the level indicator of the circular level is in horizontal alignment with the top work surface. By locating the circular level in the middle of the plate, at the same horizontal level as the work surface, this leveler table provides accuracy and repeatability for use of the flat top work surface in manufacturing steps, particularly the forming of parts where repeatability is necessary, such as the in situ forming of an automotive windshield sensor pad in an open ended package supported on the flat top surface.

Methods of fabricating a component, such as a cascade grid panel for a jet engine thrust reverser, having a plurality of cavities extending through the component, with each cavity having at least one surface with a complex contour, and related devices. A plurality of two or more mold inserts are stacked to form a mold insert stack, with the mold insert stack having a plurality of mold bosses formed by mold boss sets. The mold boss sets are each formed by a mold boss segment from each of the mold inserts. Further, the mold boss segments are affixed to respective baseplates so that the mold boss segments can be handled as a group and remain properly positioned relative to their neighboring mold boss segments.
