Provided is a sliding mechanism capable of moving a slider in at least two different directions with a simple structure. The sliding mechanism includes a guide body including a guide unit configured to guide a slider in predetermined directions; and the slider is guided by the guide unit to move in the predetermined directions. The predetermined directions at least include a first direction and a second direction which are different from each other, and the guide unit at least includes a first guide unit configured to guide the slider in the first direction and a second guide unit configured to guide the slider in the second direction.

A pyrotechnical connecting interface of a pyrotechnical vehicle safety device comprises a socket which includes a housing with a plug-in port for accepting a plug, the pyrotechnical connecting interface further comprising pins which end in the plug-in port and via which electricity for activating a pyrotechnical charge can flow, the housing being an injection-molded housing and being provided with a peripheral wall which surrounds end portions of the pins at a distance therefrom and which ends in an end face on the side facing the plug; three radial undercuts for interlocking engagement with three associated latching fingers that are part of the plug are formed on the inner face of the peripheral wall, are spaced apart from each other in the peripheral direction, are entirely closed axially as well as radially outward, and are made in an injection-molding process.

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.

A undercut processing mechanism includes: a sliding piece having a molding core for molding an undercut portion; a holder having a guide for guiding the sliding piece so that a molding core is detached from the undercut portion; and a retaining piece slidably accommodated in the holder and slidably engaged with the sliding piece. One of the holders and the retaining piece can advance/retract relative to the other thereof. The retaining piece has a first engagement element and a second engagement element to be engaged with the sliding piece. The sliding piece is guided via the first engagement element and the second engagement element so that the molding core is detached from the undercut portion and moves away from the molded product.

A core lifter having lifter bar with an elongate blade which carries a coupling head received in an elongate lifter bar coupling receiver formed in the base configured to permit pivotable, swiveling and/or translational misalignment or tolerance compensation during core lifter assembly, installation, and operation in a plastic formable material molding apparatus, including during mold cycling advantageously preventing core lifter binding and extending core lifter life. A preferred lifter has a lifter bar formed of a blade to which a lifter bar coupling ball is attached that is received in an elongate longitudinally extending channel having a transverse cross section complementary to the ball defining a bearing race in which the ball is received enabling slidable pivoting, swiveling and slidable movement of the ball and blade relative thereto including while the ball and blade are slidably moving along the race in a longitudinal or lengthwise direction relative to the base.

The present invention relates to an injection moulding system for forming an oven liner, particularly of the type that is used with microwave ovens. Oven liners are of particular benefit when used inside microwave ovens. They improve hygiene as where food spills or spurts onto the oven liner rather than an interior of the microwave oven. An injection moulding system for forming an oven liner includes: a first mould tool which defines a cavity of length (L), width (W) and height (H), the first mould tool has a substantially rectangular end face with dimensions corresponding to the width (W) and height (H) of the cavity and has a hot feed located at a centroid of its end face; and a wedge collapsing tool is received in the cavity so as to contact and engage with an external periphery of the first mould tool at selected locations in order to define a volume into which hot material feed is injected, wherein the wedge collapsing tool comprises a first part and a second part in slidable contact one with another, and the width (W2) of the second part exceeds the width (W1) of the first part of the wedge collapsing tool by at least 0.1 mm so that a split line is formed on at least one side of an interior surface of the oven liner.

An openable vehicle roof having a wind deflector device which contains a wind deflector bow, which is produced from plastic material and has a central wind deflector profiled element having lateral deployment arms. At least the wind deflector profiled element has a profile leg, which delimits a groove, which is formed on the wind deflector profiled element and is open at the bottom and runs longitudinally, and the profile leg has, on the interior thereof facing the groove, a molded-on or attached fastening apparatus for an add-on part. A tool for producing a wind deflector bow is provided.

An undercut processing mechanism includes: a molding core for forming an undercut portion; an inclined pin slidable in a first direction inclined relative to a die opening direction of a molding die during the removal of a molded product from the die; and a guide rail for guiding the movement of the inclined pin. The inclined pin has a slide block movable in contact with the guide rail. The guide rail is so formed as to contact the slide block over the entire stroke of the inclined pin so that the first direction of movement of the inclined pin may be regulated, and is also so formed as to have a shape of a high bending rigidity in a particular direction of the slide block.

An undercut processing mechanism is attached to and used in a molding die for forming a molded product having an undercut portion and allows the undercut portion, projecting in a direction intersecting a demolding direction of the molded product, to be demolded. The undercut processing mechanism includes: a holder attached to the molding die so as to be movable in a demolding direction of the molded product P; a sliding piece slidable relative to the holder and configured to form the undercut portion; and a retaining piece fixed to the molding die or formed so as to be integrated with the molding die, which retaining piece slidably retains the sliding piece. In demolding the molded product, the sliding piece moves in the direction in which the undercut portion can be demolded, by moving the holder in the demolding direction of the molded product.

A pyrotechnical connecting interface of a pyrotechnical vehicle safety device comprises a socket which includes a housing with a plug-in port for accepting a plug, the pyrotechnical connecting interface further comprising pins which end in the plug-in port and via which electricity for activating a pyrotechnical charge can flow, the housing being an injection-molded housing and being provided with a peripheral wall which surrounds end portions of the pins at a distance therefrom and which ends in an end face on the side facing the plug; three radial undercuts for interlocking engagement with three associated latching fingers that are part of the plug are formed on the inner face of the peripheral wall, are spaced apart from each other in the peripheral direction, are entirely closed axially as well as radially outward, and are made in an injection-molding process.
