In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

A method for moving a movable mold mounting plate of a molding machine, wherein the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other, wherein molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state and wherein the movable mold mounting plate is moved by a drive mechanism and/or the stationary mold mounting plate is moved by an injection device such that, when reaching a predeterminable distance of the mold mounting plates relative to each other, a parameter representing a tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value.

A safety apparatus includes a safety bar that is capable of moving in a mold clamping direction and a mold opening direction, in conjunction with a moving platen provided with a movable mold, and a latch that contacts the safety bar when a door, which is provided in a cover of an injection molding device, is open, wherein the latch includes a notch in a surface thereof on the mold-opening-direction side.

The invention relates to a moulding system (100) comprising a structure (102), a fixed mould (104) fixed to the structure (102), a first mobile mould (106) mounted with translational mobility on the structure (102) between an open position in which the first mobile mould (106) is away from the fixed mould (104) and a closed position in which the first mobile (106) is against the fixed mould (104), and a monitoring system (150) which comprises: a first reference surface (152) solidly fixed to the fixed mould (104) and parallel to the direction of translational movement (50) of the first mobile mould (106), a first sensor (154) solidly fixed to the first mobile mould (106) which comes to bear against the first reference surface (152) and is configured to measure a first distance perpendicular to the first reference surface (152), and a control unit (156) which is connected to the first sensor (154) and which is configured to detect a deviation in the first distance measured by the first sensor (154) with respect to a first tolerance band.

A method for moving a movable mold mounting plate of a molding machine, wherein the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other and wherein a drive mechanism for moving the movable mold mounting plate is provided, wherein molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state and wherein a temporally changeable tilting movement of the mold mounting plates relative to each other occurs by the movement of the movable mold mounting plate, wherein the movable mold mounting plate is moved by the drive mechanism and/or the stationary mold mounting plate is moved by an injection device in such a way that when reaching a predeterminable distance of the mold mounting plates relative to each other a parameter representing the tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value, preferably equal to zero.

Provided is a molding machine including a mold opening/closing mechanism configured to move a movable platen to be attached with a movable mold to a stationary platen to be attached with a stationary mold, and a clamping mechanism to perform a clamping process, and is intended to suppress machine cost or ensure the mold opening/closing speed. The molding machine includes the mold opening/closing mechanism configured to move the movable platen to be attached with the movable mold to the stationary platen to be attached with the stationary mold, and the clamping mechanism configured to perform a clamping process. The mold opening/closing mechanism includes at least two ball screws, at least two electric motors that respectively drive the ball screws, and a ball screw nut into which each of the ball screws is inserted.

A display device to be attached to a die, the display device including a display to rewrite and display die management information obtained in an information acquisition section to obtain the die management information for managing the die. The display uses electric power when display content is rewritten, and the display uses no electric power for keeping the display.

An open/close counting device to be attached to one of a first die and a second die which constitute a die, the die being opened by relatively moving the first die and the second die, the open/close counting device counting the number of open/close times of the die. The open/close counting device includes an open/close detecting section provided so as to face a target face of the other of the first die and the second die and to detect relative displacement of the target face along a die moving direction in non-contact condition, and includes an output section to output the open/close times counted based on detection of open/close by the open/close detecting section.

The invention relates to a system for monitoring the position of the closing unit of an injection-molding machine, by bypassing a light curtain that serves to secure the closing unit and the tool area of the injection-molding machine, wherein the injection-molding machine has at least one molding tool that consists of at least two parts, which tool encloses at least one mold cavity, wherein the injection-molding machine has a programmable logic controller (PLC) for controlling the movement monitoring module (MOC) for indirect position monitoring of the closing unit and of the position of the molding tool parts relative to one another, wherein distance measuring sticks are provided as sensors, the signals of which are processed in the PLC via the MOC, wherein the tool parts must maintain a spacing gap, relative to one another, after the closing pressure has been built up and the mold has been filled, during the subsequent bumping step, which gap has a specific maximal value assigned to it, with the injection-molding machine shutting off if this value is exceeded.
