Abstract:
A process and assembly for producing a two stage injection molded article encapsulating an oriented glass strand mat substrate. A rotary press is incorporated into the injection mold assembly and which enables repetitive repositioning of an intermediate injection molded article into a second mold defining cavity for second stage molding and simultaneous with first stage molding of a subsequent glass strand composite positioned within the first mold cavity.
Abstract:
An injection mold including at least one first mold portion, at least a second mold portion positioned facing the first mold portion, the first portion or the second portion of the mold being configured to be axially movable relative to respectively the second portion or the first mold portion between at least an opening position of the injection mold and a closing position of the injection mold, at least one first workstation called injection station, and at least a second workstation called insert laying station and/or an ejection station. An injection method implemented by the injection mold.
Abstract:
The invention relates to a method for manufacturing a rigid receptacle (10), in particular a bottle, more particularly a bottle for a cosmetic product, said receptacle having a two-layered structure comprising a first layer, referred to as the receptacle body (20), which defines a neck (22) of said receptacle (10), and a second layer, referred to as the receptacle envelope (30), which surrounds said body (20). The method according to the invention comprises a step of shaping a preform inside a component forming said envelope (30), in order to form said body (20).The invention also relates to a rigid receptacle (10) obtained according to said method, and to a device for implementing said method.
Abstract:
In an aspect, an injection molding machine is provided and incorporates a mold block with a plurality of sides including an injection side at which hollow parts are formed in mold cavities, a first post-mold cooling side whereat the hollow parts are cooled, and a part transfer side where parts are transferred out of the mold block. Optionally additional post-mold cooling sides are provided. A takeout structure is provided to remove the hollow parts from molding cores on the injection side, to transfer the hollow parts to the first post-mold cooling side, and to subsequently transfer the hollow parts to the part transfer side. The takeout structure holds the hollow parts by their neck portions and cools their neck portions.
Abstract:
A molding tool for producing an optical element includes a first mold half, a second mold half separated from the first mold half by a separation plane, a first injection station arranged at the separation plane for shaping a first layer of the optical element, a second injection station arranged at the separation plane in which a second layer can be injected on to the first layer, and a first transport device for transporting the first layer from the first injection station into the second injection station. A third injection station is arranged at the separation plane, and a third layer of the optical element to be produced is injected on to the first layer and/or the second layer. The first layer and the second layer are transported from the second injection station to the third injection station by a separate second transport device.
Abstract:
The invention relates to a retaining device (5) for a rotatable center block (17) in an injection molding device (1), comprising a lower rotary plate (14) rotatable about an axis of rotation (13) and driven by a motor (15), the lower rotary plate being used for retaining the rotatable center block (17). The retaining device (5) comprises a lower cross member (7), which is mounted movably in the longitudinal direction (x) on guide rails (9) while supported on a machine bed of the injection molding device by means of first bearing blocks (8). The retaining device (5) can have two bearing blocks (16), by means of which the lower cross member (7) is supported in the circumferential direction relative to lower beams (4) of the injection molding device. For a further increase in efficiency, the center block (17) has a main body made of a material of lower density than a coupling plate (23) operatively connected thereto.
Abstract:
The invention relates to a rotation device (1) for rotating the center part (2) in an injection-molding device. The rotation device comprises a column (3) which is non-rotatably mounted in the interior of the center part (2) and a sleeve (4) surrounding the same which is mounted such as to rotate with the center part (2), said sleeve (4) and said column (3) being operatively interconnected via a drive.
Abstract:
Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of said at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through said at least one opening into a space between the inner and outer container.
Abstract:
An injection molding machine to prevent a molded piece from being separated from a mold after molds are disassembled from each other includes a first mold, a second mold assembled with the first mold to form a cavity, and a binding device or a pressing device to get a molded piece held in the first mold when the first mold and the second mold are disassembled from each other.
Abstract:
[PROBLEM]To provide a method of molding a composite molded article enabling compression molding without requiring a large sized injection molding machine and a mold system used for that.[MEANS FOR SOLUTION]A method of molding a composite molded article using a first mold member 13 to mold a primary molded article 29 by primary molding, switching a movable mold member holding the primary molded article 29 with a movable mold member 14 positioned with a second mold member 15, then using a second mold member 15 in which the primary molded article 29 is inserted to mold a secondary molded article 30 by secondary molding, wherein the primary molding and the secondary molding are executed by non-continuous different steps at points of time different from each other.
