摘要:
The present disclosure is concerned with an injection molding device having a first mold half, an index plate that in a molding position is at least partly received in the first mold half, an index plate axle connected with the index plate, which 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 with the first mold half, wherein the adaptor plate has a drive and a first coupling element coupled with the drive, which first coupling element is arranged eccentric with respect to the longitudinal axis of the index plate axle, and 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.
摘要:
A method for producing a part by molding with an embedded 2D barcode defined in the surface of the part and the embedded 2D barcode subsequently being readable using a light source and a camera, the method including providing a mold with an array of individual areas of optical anisotropic surface structures, where at least a number of the individual optical anisotropic structures forms a two-dimensional barcode or data matrix; making a replica of the mold, the replica including the array having the property that the directional reflection coefficient of the individual areas of optical anisotropic surface structures is depending on the illumination angle and detection angle in a way that is not rotational symmetric around the axis normal to the surface of the replica, the array being readable by illumination and detection of reflection intensity of the illumination source under a non-normal angle to the surface of the replica.

摘要:
Mould for moulded parts with internal undercuts that comprises a core of the mould with two complementary parts (both fitted one inside the other), providing the possibility of axial displacement and turning among them, establishing the external element part various slots where the parallel forms that the internal element part has in its peripheral area are inserted. Thus, thanks to the axial displacement and the turning of both elements, the parallel forms come out of from the slots and deviate from the coping enabling the ejection of the moulded part without being forced.

Method for manufacturing plungers for medical syringes, whereby such a plunger (3) consists of at least two parts, namely a longitudinal plunger body (4) made of plastic and a piston body (5) provided at the front end of the plunger body (4) which consists of a plastic which is softer than the plastic of the plunger body (4), characterised in that such a plunger (3), or at least a part (36) thereof, is formed by first manufacturing the piston body (5) and then the plunger body (4), or at least a part (37) of this plunger body (4), by means of injection moulding, whereby the plunger body (4), or the above-mentioned part (37) thereof, is injected against the piston body (5).
摘要:
The invention relates to a procedure and a mechanism for the production preferably of plastic objects with hinges (3), one-component as well as multicomponent objects, as well as the closing of these. This can take place in a single tool, as the objects are being molded in one with a turnable middle section (5) provided tool, where the in the tool finish-molded object, with the hinge (3) in an open position and with the object still placed on the turnable middle section (5), is turned further forward against a new station together with the turnable middle section (5), while or whereupon one or more for the purpose serving mechanism(s) closes the hinged object to its final position in one or more rounds before or during the ejection of the closed object from the tool. The invention e.g. can be used on a flip lid (2), which is molded together with a hinge (3) and the stationary part (1) of the object. This flip lid (2) can be closed firmly on the stationary part (1) of the object by means of a closing mechanism (8), and possibly supplemented by the closing movement of the molding tool, after the procedure and mechanism according to the invention.
摘要:
Eine Spritzgießform zur Herstellung von Kugellagerringen mit Laufrillen, wobei auf einem in axialer Richtung verschiebbaren Träger in radialer Richtung Formsegmente mit Ringstegen für die Laufrillen verschiebbar sind. Das technische Problem ist die Bereitstellung einer Spritzgießform, die eine trennmarkierungsfreie Herstellung von Lagerrillen in Kugellagerringen erlaubt. Mindestens ein Formsegment (9) weist auf dem Ringsteg einen Nocken (25) zur Endformung der Laufrille (2) auf, und der Halter (11) und die Formsegmente (8, 9) sind drehbar ausgebildet.
摘要:
Method for manufacturing brush bodies for tooth brushes, in particular for injection moulding brush bodies (2) consisting of at least two components (5-9), of the type whereby at least one first injection moulding piece (25) is formed of a first component (5) in a first mould (3), consisting of at least two mould parts (4-6); whereby at least one second injection moulding piece (26) is formed by providing the first injection moulding piece (25) in a second mould (7), which also consists of at least two mould parts (8-10), and by providing a second component (9) on the first injection moulding piece (25) in said second mould (7); and whereby every injection moulding piece (25) formed in the first mould (3) is transferred to the second mould (7) by means of a transfer part (15) provided between the mould parts (4-6-8-10) of the above-mentioned moulds (3-7), characterized in that the injection moulding pieces (25) formed in the first mould (3) are secured to the transfer part (15) during the transfer to the second mould (7) for at least part of this movement by means of securing means (40) which can be activated.
