A porous plate member is positioned in one mold using a movable pin in a state in which a leading end portion including an oblique face portion provided in the one mold is projecting out toward another mold. The one mold and the other mold are clamped together to press the porous plate member, and the movable pin is pressed and retracted by the other mold. A synthetic resin material is injected into the cavity, and the flow thereof is applied to the leading end portion (42) of the movable pin to further retract the movable pin, and the synthetic resin material is cured in a state in which the synthetic resin material has entered a space in which the movable pin has been retracted, thereby manufacturing a composite member.

The first member may further comprise a post extending from the base opposite the plurality of walls and a ring disposed radially about a portion of the post, wherein the ring is configured to retain the first member within the housing. The positioning device may further comprise a second member comprising a base and a protrusion, wherein the protrusion is configured to matingly engage the void of the member.

In order to increase the degree of automation, an overmolding device for processing profiles, having a turntable with a worktable device that is movable in rotation about an axis of rotation in a rotation plane and has at least two processing areas, is proposed, wherein the processing areas each comprise a central plate, wherein the central plate is attached to and/or mounted on the worktable via a central-plate receptacle, wherein the turntable comprises an upper and a lower mold, which are decoupled from the rotation of the worktable device and which are arranged opposite one another with regard to the rotation plane, and wherein the upper and lower mold are movable such that, together with the central plate, they form a mold receiving the profile, and the central-plate receptacle (5) forms the fixed closing side and the upper and lower molds form the movable closing side.

A mold box for an injection molding machine, the mold box having a first mold plate, a second mold plate movably arranged relative to the first mold plate along a longitudinal axis, and a main guide rail system configured for guiding at least the second mold plate linearly away from and rectangular cross section perpendicular to the longitudinal axis. The main guide rail pillar extends through a third opening through a bearing arranged between the main guide rail pillar and the second mold plate. A guide track is formed as an elongate indention in a sidewall of the main guide rail pillar and has a first internal guide surface. A protruding bearing element extends from the third opening in the bearing and into the guide track.

In a mold device, a side portion of a second mold forming a second cavity portion is deformed outward in a second direction by injection pressure during injection molding, and an insert is displaced along with the deformation of the side portion. A drive portion moves the insert in a drive direction intersecting the first direction and the second direction so as to be able to advance and retract between a molding position at which the molded article can be molded and a retracted position at which the molded article can be released. The insert is swingably attached to the drive portion.

An injection mold for a high-aspect-ratio double-layer cylindrical plastic part and a molding method using the same. The injection mold includes a support base plate. A movable mold fixing frame and a movable mold base plate are arranged at the middle of a lower surface of the support base plate through positioning screws. A lower core mold is matchingly provided at a center of an upper surface of the support base plate, and is provided with a lower semicircular cavity for accommodating an outer die barrel. One side of the lower semicircular cavity is open, and the other side is provided with a first end wall which is provided with a lower semicircular notch for an inner die rod to pass through. An upper surface of the lower core mold is provided with a positioning protrusion, a lower feeding groove, and a remaining groove.

A method and device for injection moulding, in particular for micro-injection moulding, at least comprising a mould with a first mould half and a second mould half, wherein the first mould half and the second mould half define an injection moulding space in the closed state of the mould, and an insert arranged in the injection moulding space.

A positioning device for aligning and guiding a first half and a second half of a mold together. The positioning device may comprise a housing including identical wall members configured to define a cavity. Each of the wall members comprise a tab, the tab defining a recess and a protrusion on opposed sides of the tab such that the protrusion and recess defined by the tab of one of the wall member is configured to interlock with the recess or protrusion of the tab of an adjacent wall member to connect adjacent wall members. A first member may be slidably disposed within the cavity of the housing, the first member defining a void. The positioning device may further comprise a second member comprising a base and a protrusion, wherein the protrusion is configured to matingly engage the void of the first member.

An object of the present invention is to provide a blow molding device, a blow molding method, a mold unit, and a jig capable of shortening a molding cycle time. There is provided a blow molding device (100), in which the blow molding device (100) includes an injection molding part (10) injection-molding a preform (1) having a neck portion (3) on an open side and a main body portion (2) on a closed side, a temperature adjustment part (20, 520) adjusting a temperature of the preform (1) molded by the injection molding part (10), and a blow molding part (30) blow-molding the preform (1) whose temperature has been adjusted by the temperature adjustment part (20, 520), and the temperature adjustment part (20, 520) include a conditioning core mold (21, 321, 421, 521) that is in contact with substantially an entire inner surface of the main body portion (2) and a conditioning cavity mold (22, 322, 422, 522) that is in contact with substantially an entire outer surface of the main body portion (2), and compress and deform the main body portion (2) of the preform (1) into a desired shape with the main body portion (2) sandwiched between the conditioning core mold (21, 321, 421, 521) and the conditioning cavity mold (22, 322, 422, 522).

An injection molding die includes a fixed die and a movable die that move in a die opening/closing direction relatively to each other. A cavity that is formed between the fixed die and the movable die in a die clamping state includes a lateral cavity portion that extends along the die opening/closing direction and a first orthogonal direction. The injection molding die includes a demolding core and a following core that define an end portion of the lateral cavity portion across the fixed die and the movable die in a second orthogonal direction. The demolding core and the following core are configured to be movable in the second orthogonal direction while defining the end portion of the lateral cavity portion across the fixed die and the movable die in the die clamping state, and to be engaged with the fixed die with substantially no play in the second orthogonal direction.
