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.

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.

An injection molding machine which includes a mold clamping device (20) that opens and closes a mold (90) and clamps the closed mold, an injection device (30) that injects a material into the clamped mold, and an ejecting device (21) that ejects a molded product (100) molded in the mold is provided. The injection molding machine further includes a plurality of cameras (2) that photograph the injection molding machine to generate image data, a memory (6) that records the image data, an input device that sets at least one photographing time by selecting the start or end of each process in a molding cycle, and a control device that controls the camera to photograph the injection molding machine at the at least one photographing time, and controls the memory to record the image data.

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.

When the deceleration start point is reached, the meter-in side of the hydraulic driving actuator is subjected to a flow rate control to thereby start the deceleration control processing. The position to which the movable unit is moved is detected to use a speed instruction corresponding to the movement position to subject the hydraulic driving actuator to a meter-in control. The position to which the movable unit is moved is detected to calculate the moving speed of the movable unit. Based on the speed instruction, the moving speed is subjected to the feedback control using the meter-out control to the hydraulic driving actuator.

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.

When the deceleration start point is reached, the meter-in side of the hydraulic driving actuator is subjected to a flow rate control to thereby start the deceleration control processing. The position to which the movable unit is moved is detected to use a speed instruction corresponding to the movement position to subject the hydraulic driving actuator to a meter-in control. The position to which the movable unit is moved is detected to calculate the moving speed of the movable unit. Based on the speed instruction, the moving speed is subjected to the feedback control using the meter-out control to the hydraulic driving actuator.

An injection molding tool for producing a molded part and a corresponding method are disclosed. The injection mold tool comprises a first tool mold half and a second tool mold half, which together with a first slider and at least one second slider define a free space for the molded part to be produced. A lever which is pretensioned with an elastic element is assigned to an end switch such that a movable and free end of the lever cooperates with the end switch due to a movement of the first slider.
