An injection-molding tool has a cavity-forming die and a cavity-forming core pin, which form at least a part of a cavity, provision is made for the injection-molding tool to comprise at least one core-centering device for centering and supporting the core pin. The core-centering device comprises at least one retaining pin guided in a bore of the cavity-forming die. The retaining pin is in contact with the core pin by way of an end face in a retracted position and, in an extended position, is drawn back such that the end face does not project beyond an inner surface of the cavity-forming die, in which the bore ends.

An injection molding device for producing a multicomponent injection molded product includes at least one first and at least one second outer mold plate arranged in a movable manner between an open position and a closed position. A central part arranged between the first and the second outer mold plate includes a first part which in the open position is arranged rotatable about an axis of rotation and to which first inner mold plates are attached which include first cavity segments. A second part arranged non-rotatable includes on one side in the direction of the first outer mold plate second cavity segments and on an opposite side in the direction of the second outer mold plate third cavity segments. Second inner mold plates clamp related intermediate products and in the open position are arranged displaceable in a radial direction with respect to the axis of rotation and rotatable around the second part to transport the intermediate products from the second cavity segments to the third cavity segments around the second part of the central part.

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.

A one-piece part and a method of making the one-piece part. The one-piece part comprises an upper wall; a lower wall having an exterior portion and an interior portion, the interior portion overlapping the upper wall; lateral walls connecting the upper wall to the lower wall; an intermediate wall connecting the upper wall to the lower wall, the intermediate wall extending longitudinally between the lateral walls; a bottom wall connecting the lateral walls and the lower wall; and a top wall connecting the lateral walls and the upper wall, wherein the lateral walls, the top wall, the bottom wall, the exterior portion of the lower wall, the intermediate wall, and the upper wall have exterior surfaces and interior surfaces, the interior surfaces defining a volume of the one-piece part, and wherein the interior portion of the lower wall extends into said volume.

A mold system for making a medical device includes a mold having a mold cavity for receiving a material; first and second core pins, each having a first lumen-defining section located, or otherwise configured for placement, in the mold cavity; and a spacer tool having a lumen sized for accommodating a first tube that is in a fixed position with respect to the mold, wherein a first end of the first tube is engaged with the first lumen-defining section of the first core pin, and wherein the spacer tool comprises a first section configured for placement in the mold cavity of the mold, the first section of the spacer tool having a first outer cross-sectional dimension that is larger than an outer cross-sectional dimension of the first tube.

The invention relates to a method for producing a syringe with an integrated closure element, which method comprises the following method steps: a) making available an injection moulding tool which comprises a first, a second and a third tool portion, wherein the first tool portion has a mould cavity open at both sides and extending along an axial direction (X), and wherein the second tool portion has a first injection moulding core and the third tool portion has a second injection moulding core; b) closing the injection moulding tool such that the first tool portion contacts the second and third tool portion, and the first and second injection moulding core each enter the mould cavity of the first tool portion through an opening and finally contact each other, as a result of which these tool portions form a first structural cavity; c) injecting a first plastic material into the first structural cavity, as a result of which a hollow cylindrical syringe body is formed with an end region at its distal end, wherein the end region has an attachment element, provided with an inner thread, and a hollow cylindrical endpiece which is at least partially bounded by the attachment element; d) cooling the tool portions, as a result of which the syringe body cools and hardens; e) bringing the first tool portion into contact with a fourth tool portion provided with a mould cavity closed at one end, as a result of which a second structural cavity is formed at the distal end of the syringe body; f) injecting a second plastic material into the second structural cavity, as a result of which the closure element is integrally formed on the attachment element, wherein the first and the second plastic material do not enter into a cohesive connection.
