The in-mold shutter (140, 240, 340, 440, 540) includes a shutter actuator (148, 548) that is configured to selectively engage a first mold shoe (130) of the injection mold (100, 200, 300) with a platen of a mold clamping assembly (996) to hold the first mold shoe (130) in an extended position (E), along a mold-stroke axis (X), during a step of molding a first molded article (102A) in the injection mold (100, 200, 300). Also described herein is a molded article transfer device (150, 250) for use with the injection mold (100, 200, 300). The molded article transfer device (150, 250) includes a shuttle (154) that is slidably arranged, in use, within the injection mold (100, 200, 300). The shuttle (154) defines a first aperture (156A), at least in part, that alternately accommodates: (i) a first mold stack (106A, 206A, 306A) arranged therein; and (ii) a first molded article (102A) received therein with opening of the first mold stack (106A, 206A, 306A).

A heater and thermocouple assembly for use with a hot runner nozzle with an elongated heater body, said heater body having at least one first heating section, which in operation is positioned adjacent to the front end portion of the hot runner nozzle, and at least one second heating section which in operation is positioned adjacent to a nozzle head of the hot runner nozzle and has an at least partly annular distance section with a wall which is arranged between the first and second heating sections.

An injection tooling is configured to inject a polymer resin into a fiber preform for fabricating a part in the form of a body of revolution out of composite material, the part having an internal cavity with back-draft. In order to enable the part to be unmolded after the polymer resin has been injected and polymerized, the tooling includes, arranged at least in the internal cavity, firstly a sectorized ring made up of at least three mutually touching inserts including one forming a keystone, the ring having an outside surface that matches the internal cavity with back-draft and an inside surface that presents natural draft, and secondly a conical drum secured to the inside surface of the sectorized ring to support it and that is withdrawn, once separated from the sectorized ring, relying on the natural draft created by the inside surface of the sectorized ring.

A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is there removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.

A method and device for injection moulding micro-components, including an injection moulding machine having a mould carrier, which supports a removable mould in which at least one mould cavity is provided; and a counter mould, which is arranged so as to be closed against the mould in such a way as to apply a centering force as well as moulding pressure to the mould when the counter mould is closed against the mould.

The separating device comprises: an actuating device (8) translatable along a first axis (A1) between a retracted position and a separated position, at least one separating element (28, 60) translatable along a second axis (A2) between a retracted position and a separated position, a transfer device (26) connecting the actuating device (8) and the separating device (28, 60).

The transfer device (26) comprises at least two links (46), rotatable relative to one another and relative to the actuating device (8) and the separating element (28, 60), and a guide element (36) receiving said links (46), said links being moved along a movement path by the actuating device (8) and moving the separating element (28, 60).

The ejection device comprises: a pushing device (14) translatable along a first axis (A1) between a retracted position and an ejection position, an ejection element (28) translatable along a second axis (A2) between a retracted position and an ejection position, a transfer device (26) connecting the pushing device (14) and the ejection device (28).

The transfer device (26) comprises at least two links (44), translatable relative to one another and relative to the pushing device (14) and the ejection element (28).

An injection mold and a device for preparation of a light guide plate are provided by embodiments of the present disclosure. An injection mold, comprising a male mold and a female mold which cooperate with each other to define collectively a molding cavity adapted for molding a sheet component therein; a blowing device is provided in the male mold and configured to blow out gas with a predetermined pressure towards a bottom surface of the sheet component molded in the molding cavity to overcome at least partially a vacuum adsorption force between the bottom surface of the sheet component and an internal bottom surface of the molding cavity such that the sheet component is separated from the male mold. Therefore, the sheet component can be demoulded successfully and prevented from a relatively large warping deformation during a demoulding process such that the quality thereof can be guaranteed.

An injection molding device has a first mold half, an index plate that in a molding position is at least partly received in the first mold half, and an index plate axle connected with the index plate. The index plate axle is arranged for linear movement along its longitudinal axis relative to the first mold half so that the index plate can be moved between the molding position and a turning position in which the index plate can be rotated with respect to the first mold half. An adaptor plate, connected to the first mold half, has a drive and a first coupling element coupled with the drive. The first coupling element is arranged eccentric with respect to the longitudinal axis of the index plate axle. The first mold half has a second coupling element engaged with the first coupling element. The second coupling element is coupled with the index plate axle for rotating the index plate axle around the longitudinal axis.
