Abstract:
The invention concerns an elastic element (100) made of a plastic material for a device (1) for dispensing fluids (L), comprising a tubular body (129) that develops around a main longitudinal axis (X), comprising a main portion that develops according to a spiral-shaped pattern and extends longitudinally between a first end portion (100a) and a second end portion (100b) opposite the first end portion (100a). One of the first and second end portions comprises a first projection (151) extending from the internal surface of the tubular body (129) towards the inner space defined by the tubular body (129). The invention furthermore concerns a method for making an elastic element (100) through an injection moulding process, a mould (200) for making an elastic element (100).

A liftgate having an overmolded hinge point comprising a metal reinforcement overmolded with a polymer and having a compression limiter portion molded in. The compression limiter portion including a tubular portion for receiving a fastener encapsulated during overmolding and having overmolded gusset ribs extending therefrom during the overmolding process.
Abstract:
A mold structure used in an injection molding process to form a cup having broken threads where an “A” and “B” mold form a horizontal irregular parting line to alleviate stripping or unscrewing along the threads. The “B” mold includes a series of segmented surfaces arranged in a helical pattern at an angle from a transverse plane and extending around a longitudinal axis to form a topside surface of the “B” mold. The “A” mold having a series of corresponding segmented surfaces similarly constructed and arranged to mate with the “B” mold. Closed-ended flutes are disposed on an inner wall surface of each segmented surface on either the “A” or “B” mold. A core insert is disposed within but having a space thereinbetween inner wall surfaces of the top and “B” mold and abutting the closed “A” mold portion and closed “B” mold portion creating a seal off.
Abstract:
A mixing baffle for mixing a fluid flow includes a longitudinal support structure and a first set of moveable mixing elements integrally molded with and extending from the longitudinal support structure. The first set of moveable mixing elements are molded in a first configuration and deform to a second configuration. The first set of moveable mixing elements may deform when the mixing baffle is inserted into a conduit. A static mixer for mixing a fluid includes a conduit and the mixing baffle inserted in the conduit.
Abstract:
The present invention provides a die assembly for molding a resin-made insert having a sleeve that is inserted into an intake port of an internal combustion engine. Each sleeve has one inlet and two outlets. The die assembly includes an inner die and an outer die. The inner die includes an inlet side part and an outlet side part. The inlet side part and the outlet side part mold an inner peripheral surface of the sleeve in an assembled state, and are removed in mutually opposite directions. By means of this assembly, a sleeve having a complicated structure and shape can be molded easily.
Abstract:
A projection mechanism of a molding die configured to mold a molded article by a fixed-side die and a movable-side die, the projection mechanism including: a projection pin using a reaction force of a spring as a drive source; and a first spring and a second spring configured to project the projection pin, wherein the first spring has a maximum reaction force in a die clamping state, and projects the projection pin while gradually reducing the reaction force in a projection process, and the second spring projects the projection pin with a constant reaction force while projecting the projection pin from the die clamping state, where stop of movement of the second projection pin during the projection process causes compression of the second spring to increase the reaction force of the second spring, thereby energizing the projection pin to further project the projection pin.
Abstract:
A method for producing a cable spool including the steps of providing a mold for producing a cable spool, assembling said mold by joining said at least two central mold pieces and said first and second flange mold pieces, adding molten polymer material to said mold, removing said mold and cooling said cable spool. Also, a mold for producing a cable spool, said mold including at least two central mold pieces, a first flange mold piece and a second flange mold piece. Also, a plastic cable spool including a barrel and two annular flanges located at opposite ends of said barrel, wherein each one of said flanges has an inward facing side directed towards said other flange and an outward facing side, and each one of said flanges includes a through-hole extending between said inward facing side and said outward facing side.
Abstract:
A body (1, 1′, 1″) produced by an in-mold process has a first film (2, 2′, 2″) with at least one electrical or electronic functional layer (25). In a functional area (20a, 20a′, 20a″) of this functional layer, at least one electrical or electronic component is provided, and at least one electrical connection for this is provided in a contact area (20b, 20b′, 20b″). The first film is partially back-injection molded with a plastic main material (3, 3′, 3″) such that the contact area (20b, 20b′, 20b″) is at least partially free from this plastic main material (3). Suitable formation of the first film (2, 2′, 2″) guarantees that a tab (F) separated from the plastic main material (3, 3′, 3″) is provided which adjoins a back-injection molded part of the first film in an area of surface (20c, 20c′, 20c″) of the body which is at a distance from an edge (31, 31′) of the body delimiting the surface (30) with the first film.
Abstract:
A closure is provided with a closure bottom that is designed to close off a container opening. A circumferential wall is connected to the closure bottom. The circumferential wall has an inner thread that is formed of two or more thread sections spaced apart from each other in a circumferential direction of the circumferential wall. The inner thread has a thread axis. The closure bottom has at least one demolding opening and the at least one demolding opening overlaps at least one of the thread sections, when viewed in the direction of the thread axis of the inner thread. An injection mold with only a first mold half and a second mold half is provided for molding the closure.
Abstract:
A thin type injection molding skin manufacturing apparatus in which a mold movable part moves to be separated from a mold fixing part at a time of taking out a skin to open a mold, may include a holder part cavity for molding a holder part formed integrally with the skin, which is formed inside the mold fixing part and a fixing part slider capable of elastically pressing the holder part molded in the holder part cavity installed on the end of the holder part cavity, and as a result, the fixing part slider presses and holds the holder part molded integrally with the skin when the mold movable part moves to be separated from the mold fixing part.
