The management system has an injection molding machine and a management unit for managing the injection molding machine, wherein the management unit includes: a plurality of physical quantity measurement units configured to be provided at a plurality of movable parts included in the injection molding machine; an ascertainment unit configured to calculate, based on a plurality of physical quantity data respectively measured by the plurality of physical quantity measurement units, a comparative relationship representing a relational state of the plurality of physical quantity data between the plurality of the movable parts, and to ascertain whether the comparative relationship deviates from a preset reference comparative relationship; and an alarm unit configured to issue an alarm when the ascertainment unit ascertains that the comparative relationship deviates from the reference comparative relationship.

An injection molding machine includes: a controller configured to instruct an operation indicated by first or second operation information associated with at least either first or second image information displayed on a display, or to execute processing by a system program, wherein the first and second operation information is information about an injection molding operation according to a first or second production condition, and operation information about first and second molds or operation information about a mold clamping mechanism from beginning to completion of the injection molding operation, the display displays a plurality of operating points indicating positions of the first mold, the second mold or the mold clamping mechanism relative to time or process from the beginning of the injection molding operation, and line segments connecting the plurality of operating points, and the first and second image information are displayed on the operating points.

An injection machine which includes a mold falling prevention device that prevents a mold fixed to a mold fixing surface from falling off from the mold fixing surface and in which are provided a bottom edge restriction member at a lower portion of said mold fixing surface so that its vertical position is variable, for implementing restriction so that the bottom edge portion of the mold does not separate from the mold fixing surface, first and second intermediate restriction members at intermediate level portions of the mold fixing surface so that their horizontal positions are variable, for respectively implementing restrictions so that a one edge portion of the mold and an other edge portion thereof in the horizontal direction do not separate from the mold fixing surface, and a vertical direction position determination mechanism that receives and stops a bottom edge surface of the mold and determines a position of the mold in the vertical direction.

A system for programming a protection device for a molding machine includes a controller for actuating a plurality of molding machine actuators in an actuation sequence, each distinct actuation constituting a respective machine component actuation of an associated machine component. An HMI is operable to: present a GUI specific to a chosen machine component actuation; and for each of a plurality of other machine component actuations, define within the GUI, based on operator input, a rule specifying a state of the chosen machine component actuation relative to a state of the other machine component actuation for preventing interference between the two machine component actuations. The controller is configured, based on the rules defined within the GUI, to trigger an action, upon violation of any one of the rules, for reducing a risk of interference between the chosen machine component actuation and a respective one of the other machine component actuations.

A moulding assembly with an inlet for receiving raw material to be ejected is disclosed. The moulding assembly may include: a barrel for gathering and processing the raw material received through the inlet, a screw for engaging the raw material in the barrel, and a first drive unit configured for rotating the screw in order to grind the raw material into liquid form. The moulding assembly may further comprise a second drive unit configured to displace the screw in a direction essentially perpendicular to the rotation direction in and out of the barrel depending on the pressure in the barrel.

A controller includes a mold movement control unit that moves a movable mold between a first position separated from a fixed mold and a second position at which mold closing is completed; a determining unit determines the presence of abnormalities in at least one of the movable mold and the fixed mold on the basis of inspection information acquired from at least one of the movable mold and the fixed mold and outputs a confirmation signal related to the presence of abnormalities; and a mold stopping unit that stops movement of the movable mold on the basis of whether the confirmation signal output from the determining unit is acquired while a safety confirmation condition is satisfied after the mold movement control unit starts moving the movable mold from the first position toward the second position.

In order to calculate a ball screw abrasion amount of an injection-axis ball screw or a mold-clamping-axis ball screw, a position of a ball nut fitted to the ball screw is photographed by a camera installed in an injection molding machine. Then, if the photographed position of the ball nut is found, as a result of analysis of an image captured by the camera, to be deviated from the position of the ball nut when a ball screw has no abrasion, it is determined that the ball screw is abraded.
