The invention relates to a device for handling and/or transporting workpieces (5), in particular for removal of injection-molded items from an injection-molding machine, wherein a handling robot (4) having a programmable control and regulating unit (10) is provided that comprises a gripper (6) having at least one suction nozzle (7) for grasping of the workpiece (5) or fixating it by suction. In the gripper (6) of the handling robot (4) a distance-measuring device (8) for detection of the distance (a.sub.1+a.sub.2) from the gripper (6) to a reference point or a reference surface (9), for example to the mold tool half (2), which is preferably movable, with the workpiece (5), is provided. The measured value of the distance-measuring device (8) is fed into the control and regulation unit (10). The distance-measuring device (8) can be a light-transit time measuring device, in particular a time-of-flight (TOF) sensor.

A molding system for assembling a part by moving a workpiece griped by a hand of a robot toward a mold of an injection molding machine, while rotating a molded article supported on the mold and the workpiece relative to each other, whereby the molded article and the workpiece are screw-engaged. The molding system includes a rotation detector for detecting a rotational amount between the molded article and the workpiece, an assembled state judging unit for judging if the assembled part is in a predetermined state, and a control unit for relatively rotating and displacing the molded article and the workpiece until the rotational amount exceeds a predetermined rotational amount and the assembled state becomes the predetermined state.

Disclosed herein, amongst other things is a component of a molding system (e.g. mold component, post-mold component, etc.) having a heat dissipater that is configured to impart a profiled heat removal rate on a selected portion of a molded article that generally matches a heat distribution therein.

Provided is an attaching/detaching structure that operates reliably with simple operation. The attaching/detaching structure attaches/detaches a second connecting member (4) to/from a first connecting member (3). An operation chamber (8) formed in a base member (5) of the second connecting member (4) is connected to the outside of the base member (5) via an insertion hole (7) opened to a seating surface (6) of the first connecting member (3). Two clamp arms (10) and (11) are provided in the operation chamber (8) so as to be symmetrical around an axial center of the operation chamber (8). An engaging portion (16, 17) is formed at one end (10b, 11b) in longitudinal direction of each of the clamp arms (10, 11). An engaging member (32) protruding from the second connecting member (4) can be inserted into the insertion hole (7). A lock portion (34) in which the engaging portions (16, 17) can be engaged is formed in the engaging member (32).

This injection molding system can correct a change in position of a movable mold due to a mold clamping force adjustment mechanism, and is provided with: an injection unit that injects a resin into a cavity formed by a movable mold and a fixed mold; a mold clamping unit that retains the movable mold and the fixed mold to be openable and closable and has a mold clamping force adjustment mechanism that adjusts mold clamping forces of the movable mold and the fixed mold; a handling unit that performs at least one of the assisting operations of an operation of extracting a molded article from the movable mold and an operation of inserting an insert component into the movable mold; and a control system that controls the injection unit, the mold clamping unit, and the handling unit. The control system has a mold position detection portion that detects the position of the movable mold during mold opening, and an operation position adjustment portion that adjusts at least one of the position of the handling unit during the assisting operation and the position of the movable mold during the mold opening according to a detection value of the mold position detection portion.

Preforms with a neck region and a preform body and having an enlarged geometry in comparison with the cavity of the injection mold are produced by injecting a polymer melt into the mold with a geometry of the cavity in the mold such that the radial extent of an inner space in the preform body thereby produced is not greater than the radial extent of the inner space in the neck region, the preforms are removed from the open mold by a removal gripper, and the preforms in the removal gripper are inflated using positive pressure such that the geometry of the inflated preform body is larger than the cavity in the injection mold.

A molding system capable of performing highly accurate work on a molded article with a molded article removal device. The molding system includes a molding machine, a molded article removal device capable of removing a master work installed in a mold of the molding machine, a measurement section configured to measure a position of the master work when the master work is removed by the molded article removal device, a displacement calculation section configured to calculate a difference between a reference position and a detected position of the master work measured by the measurement section as a displacement, and a correction section configured to, on the basis of the displacement calculated by the displacement calculation section, correct a work position for when the molded article removal device performs work on a molded article.

The present invention relates to an injection mold plate for use in an injection mold for producing molded articles, comprising a plurality of handling elements arranged in columns and rows, wherein the distance r between adjacent handling elements within the rows is greater than the distance s between adjacent handling elements within the columns. According to the invention, in order to provide an injection mold plate of the type mentioned above for which the distance between adjacent handling elements can be reduced without impairing the generally required heating channel, it is proposed that a row of handling elements is formed by two groups of handling elements, wherein the following applies to the distance z between the group: z=r(1+a/n), wherein r is the distance of the handling elements within a group and n, a IN with n>1.

An injection molding system capable of easily calculating relative position information between a movable part of an injection molding machine and a movable part of a peripheral device is provided. A first control unit 110 of an injection molding machine 2 calculates first relative position information which is relative position information of a first movement position M1 set to a movable part 50 in relation to a first reference position K1 set to a first connection portion 80. A second control unit 210 of a robot 3 calculates second relative position information which is relative position information of a second movement position M2 set to a hand 65 in relation to a second reference position K2 set to a second connection portion 85. The first control unit 110 and the second control unit 210 calculate inter-drive-unit relative position information which is relative position information between the first movement position M1 and the second movement position M2 on the basis of the first relative position information and the second relative position information.

A work transferring system includes: a hand including a body and at least one attracting part configured to hold a work with a gap maintained between the work and a surface of the body by attracting the work to a distal end protruding from the surface; a transfer mechanism configured to transfer the work to a predetermined transfer destination by moving the hand; a work releasing member disposed above the transfer destination to which the transfer mechanism transfers the work and configured to release the work from the attracting part; and an lifting mechanism configured to move up and down the work releasing member or the work. The work releasing member includes a claw arranged in a substantially horizontal cantilever manner and having a shape that allows insertion of the claw into the gap.
