TRANSFER SYSTEM HAVING AN INJECTION DEVICE INTEGRATED IN FEED TABLE
A transfer system which can be used in a flexible manner for transporting or processing, respectively, profiles, in which the injection device comprises a mold for receiving the profile during the injection, wherein the mold has at least two contour parts and the injection device has a closing unit for opening/closing the contour parts, wherein the closing unit is configured for keeping the contour parts open until the profile is enclosed by the contour parts, and wherein the transportation device is configured for moving, preferably not rotating, the profile exclusively parallel to the transportation path, wherein the closing unit and the injection device are assembled so as to be displaceable conjointly with the first feed table, and the first feed table in the direction of the transportation path is displaceable so far until the contour parts enclose the profile.
Mold clamping device
A mold clamping device includes a base, a stationary platen fixed to the base and supporting a stationary mold, a movable platen movable on the base and supporting a movable mold, and a mold clamping mechanism for clamping the movable mold against the stationary mold. Tie bars extend from the stationary platen completely through both the movable platen and the mold clamping mechanism. A shaft supporting plate is fixed to the ends of the tie bars and terminates at its lower end portion in two spaced-apart shoes that have flat bottom surfaces in direct sliding contact with the base. The flat bottom surface of each shoe has a larger area than the cross-sectional area of the shaft supporting plate situated vertically above the shoe.
Pull or push rod or locking nut for a molding machine
A pull or push rod for a molding machine having a groove. The groove is suitable for forming a positive-locking connection with a locking nut, by which positive-locking connection forces are transmittable between the locking nut and the pull or push rod. The groove has a groove cross-section, has at least two groove flanks, and has a groove base. The at least two groove flanks, viewed in the groove cross-section, each transition with at least one transition curvature into the groove base. The groove base in the groove cross-section is at least partially formed as a curvature, and the curvature of the groove base differs from the transition curvatures of the groove flanks.
Pull or push rod or a locking nut for a molding machine
A pull or push rod or locking nut for a molding machine has an undercut, and the undercut has an undercut cross-section, a side wall, and an undercut ramp. The side wall transitions via a first transition curvature into an undercut base, and the undercut base transitions via a second transition curvature into the undercut ramp. The undercut base, viewed in the undercut cross-section, is at least partially curved, and the curvature of the undercut base differs from the first transition curvature and/or the second transition curvature.
Closing unit for a shaping machine
A closing unit for a shaping machine includes mutually moveable mold mounting plates suitable for carrying mold tool portions, a first hydraulic cylinder adapted to apply a closing force to the mold mounting plates, a second hydraulic cylinder, and a pressure storage device connected to the first hydraulic cylinder and adapted to store a pressure prevailing in the first hydraulic cylinder upon pressure relief at a storage device pressure. A hydraulic interconnection of the pressure storage device with the second hydraulic cylinder allows the storage pressure stored in the pressure storage device to be used for locking and/or unlocking the locking device.

Injection device and injection molding machine
An injection device includes: a heating cylinder; a screw disposed in the heating cylinder; and a pair of piston cylinder components disposed on two sides of the heating cylinder. The pair of piston cylinder components are installed so that one end portion of each of the pair of piston cylinder components is connected to a mold clamping device, and the heating cylinder and the screw are integrally driven in a direction close to or away from the mold clamping device by expansion and contraction of the pair of piston cylinder components. One of the pair of piston cylinder components is provided with a stop mechanism configured to stop expansion and contraction of the piston cylinder component.
MOULD-CLOSING UNIT FOR AN INJECTION MOULDING MACHINE, AND METHOD FOR LOCKING A FORCE TRANSMISSION ELEMENT
A mould-closing unit for an injection moulding machine for processing plastics has a mould support which is movable relative to a stationary mould support (10). A mould-moving device is provided to move the movable mould support into and out of closure of an injection mould. At least one force transmission element is connected to the movable mould support and at its end remote from the movable mould support has a section (14a) which is assigned to the stationary mould support (10) and can be actuated for operative engagement. The stationary mould support (10) is assigned a locking device (15), which can be moved into interlocking operative connection with the actuatable section (14a) to apply a closing force during closure of the injection mould. According to the method, these elements are used to create a method for locking a force transmission element to a mould support of the injection moulding machine. The fact that the locking device (15) has floating clamping jaws (16) which can be moved into interlocking operative connection with the actuatable section (14a) during closure of the mould to lock the force transmission element and the stationary mould support (10) and at the same time are connected to at least one piston (18) of a piston-cylinder unit (17) for applying the closing force, means that a mould-closing unit is created in which the locking mechanism for locking the tie bars to the mould support is integrated in a common unit with the unit for applying the closing force.
Method for controlling injection molding machine and injection molding machine
In an injection molding machine in which intermediate molds are disposed movably in a mold opening/closing direction between a movable platen attached with a movable mold and a stationary platen attached with a stationary mold, setting is simplified when individually setting a setting value related to molding using the movable mold and the intermediate mold and a setting value related to molding using the stationary mold and the intermediate mold. In a method for controlling an injection molding machine in which intermediate molds are disposed movably in a mold opening/closing direction between a movable platen attached with a movable mold and a stationary platen attached with a stationary mold, single setting enables setting of both of a setting value related to molding using the movable mold and the intermediate mold and a setting value related to molding using the stationary mold and the intermediate mold.
PNEUMATIC IN-MOLD LID CLOSING APPARATUS
An in-mold lid closing apparatus comprises a frame, a first actuation assembly configured to linearly position a lid engagement member between a first and second linear position relative to an in-mold lid, and a second actuation assembly configured to rotatably position the lid engagement member between a first and second rotational position relative to the in-mold lid. The first actuation assembly comprises a first support moveably coupled to the frame and a first actuator coupled to a frame support of the frame and a first actuator drive element coupled to the first support. The second actuation assembly comprises a second support moveably coupled to the frame and disposed between the frame support and the first support and a second actuator coupled to the second support and a second actuator drive element coupled to the first support.
