An injection mould having a first mould half (17) and a second mould half (18) which can be displaced relative to the first in a first direction (z). At least one of the mould halves has a slider arrangement (1) for forming a mould cavity (15). The slider arrangement (1) includes at least two sliders (2) which are moveable relative to one another between a closed and an open position and which are arranged so as to be displaceable with respect to a component (3), adjacent to the sliders (2), of the associated mould halves (17, 18) by means of first and second guide means (6, 7) respectively. A slider drive (4) is used to displace the sliders (2) between the open position and the closed position.

An inner mandrel for forming a variable taper component includes a master insert and a plurality of interlocking pieces. The master insert includes opposed tapered edge faces, each tapered edge face defining at least one locking feature, a first surface having a variable taper and a plurality of recesses configured to receive a portion of the variable taper component, and a tapered second surface opposite the first surface. Each interlocking piece includes opposed tapered edge faces, one of the opposed tapered edge faces defining a locking feature and another of the opposed tapered edge faces defining a receiving feature to engage the locking feature of an adjacent interlocking piece, a first surface defining a variable taper and a plurality of recesses configured to receive a portion of the variable taper component, and a tapered second surface opposite the first surface.

A mold for injection molding of a plastic cap having protruding internal portions is provided. The mold has a male mold and a female mold that form a molding cavity. The male mold consists of a mobile portion fitted above a fixed portion, the mobile portion being rotatable around the fixed portion and provided with grooves having an inclined lateral surface that defines an outlet ramp. A method for producing a plastic cap by use of the mold is also provided. The method includes rotating the mobile portion of the male mold with respect to the plastic cap until flat walls of the mobile portion are located in the region of protruding portions of the plastic cap, thereby causing a slight circumferential expansion of the skirt of the plastic cap.

Provided is a molding method of a sealing cover, realized by setting up a sealing cover mold, the mold includes a cavity and a core group arranged in the cavity, including setting up a first core and a second core, the mold opening direction of the first core and the second core are not parallel. The present application does not need a process hole to perform the injection molding of the sealing cover with a fastening structure, whose sealing is also better.

A mold for molding a body or cap for a connector. The mold comprises a mold body (1) and an axial core (2) which together define a mold cavity in the shape of the body or cap. The core has a sleeve (3) and an inner pin (4) each having complementary castellations (8, 10) which interdigitate in a first configuration. In the first configuration, the castellations (8, 10) are arranged such that respective recesses (11) are formed each bound by the proximal end of a first castellation (8) and the side walls of adjacent second castellations (10). Each recess has a shape to form a respective first portion of the body or cap. The sleeve (3) and inner pin (4) are axially movable to a second configuration in which the castellations (8, 10) are disengaged from one another. The inner pin (4) is rotatable to a third configuration in which the first castellations (8) can be axially withdrawn following a path occupied by the second castellations (10) in the first configuration.

A hybrid mandrel for forming a composite part may comprise a core and a sleeve located around the core. The core may include a rigid material. The sleeve may comprise an elastomeric material. The part may be formed by locating the hybrid mandrel in an injection mold, depositing a molten resin around the hybrid mandrel, curing the molten resin; and removing the hybrid mandrel.

A method of constructing a mandrel generally complementary to a spar cavity of a spar includes connecting a first component and a second component to form a central space there between and inserting a center component within the central space such that the center component retains the first component and second component in a desired position forming an outer surface of the mandrel which corresponds to an inner surface of the spar cavity.

A device for forming components having a cavity comprises a core extending along a center axis and configured to fit into the cavity to machine the component with a forming process, the core is configured to be pulled out of the cavity after machining; the core comprises segments in mutually parallel arrangement, which are adapted to be alternated between a machining configuration and an extraction configuration, the segments are locked together in the machining configuration to prepare the core to machining, the segments are able to slide relative to each other in the extraction configuration, to reduce the diameter of the core and pull it out of the cavity; the device further comprises drive means of the segments to move them at least from the machining configuration to the extraction configuration.

Tooling for use in forming a variable taper component is provided. The tooling includes an inner mandrel and an outer mandrel disposed around the inner mandrel. The inner mandrel includes a master insert defining opposed tapered edge faces, an external surface having a variable taper and a plurality of recesses configured to receive at least a portion of the variable taper component, and a tapered internal surface. The inner mandrel also includes a plurality of interlocking pieces arranged concentrically around the master insert, and a tapered inner sleeve disposed against the tapered internal surfaces of the plurality of interlocking pieces and the master insert. The outer mandrel defines a corresponding plurality of recesses configured to receive at least a portion of the variable taper component, wherein a maximum width of the interlocking pieces and the master insert is smaller than a minimum width of ends of the variable taper component.

An injection mould having a first mould half (17) and a second mould half (18) which can be displaced relative to the first in a first direction (z). At least one of the mould halves has a slider arrangement (1) for forming a mould cavity (15). The slider arrangement (1) includes at least two sliders (2) which are moveable relative to one another between a closed and an open position and which are arranged so as to be displaceable with respect to a component (3), adjacent to the sliders (2), of the associated mould halves (17, 18) by means of first and second guide means (6, 7) respectively. A slider drive (4) is used to displace the sliders (2) between the open position and the closed position.
