An injection molding machine, which includes a safety door that can be opened and closed, is further equipped with a servo motor configured to open and close the safety door, a presence detector configured to detect whether or not an operator or object is present within a door operating space of the safety door or within a predetermined vicinal area of the safety door including the door operating space, and a controller configured to control the servo motor with a reference control amount in order to perform a closing operation of the safety door, and during a time it is detected by the presence detector that an operator or object is present, to cause a control amount that controls the servo motor in order to perform the closing operation of the safety door to decrease from the reference control amount.

An injection molding machine capable of opening/closing a movable mold relative to a stationary mold by moving a crosshead backward and forward to move a movable platen backward and forward relative to a stationary platen through a toggle link. The injection molding machine includes a reciprocating mechanism that receives a counterforce exerted on the crosshead in the back-and-forth direction when the movable mold and the stationary mold are closed, and a load acquisition unit that acquires a load exerted on the reciprocating mechanism in a direction perpendicular to the back-and-forth direction of the crosshead.

A rapid mold replacing device for use in molding machine includes: a mold having lateral walls at two ends disposed with a pair of bolt slots; a pair of fastening members, having a locking member connected at an outer side of each fastening member, and protruded with a locking bolt, and a top surface of each locking member having an unlocking slot; and an unlocking mechanism, disposed on a top surface of the elevation seat and having at least one first retractable driving device, and a pair of unlocking blades capable of being synchronously driven by the first retractable driving device; when the pair of unlocking blades are inserted in or released from the pair of unlocking slots, the mold can be formed in an un locked or a locked status to the mold.

A mold assembly includes a first mold portion defining a cavity having a first wall with an edge and a second mold portion defining a surface positionable at a predetermined distance from the edge. A lifter is positionable within the cavity and is spaced apart from the first wall and the surface, the lifter including a plurality of pins extending toward the first wall and aligned in a first direction generally parallel with the edge.

A control method for an injection molding system including a first housing including a first accommodation space having an injection molding machine arranged therein and a first window, a second housing coupled to the first housing and having a second accommodation space having a robot disposed therein and a second window, the robot performs an operation with respect to a molded article molded by the injection molding machine, and a control device that controls driving of the injection molding machine and the robot, the control method includes in a first state in which the first window and the second window are closed, driving the injection molding machine in a first drive mode, in a second state in which the first window is open, stopping the injection molding machine, and in a third state in which the second window is open, driving the injection molding machine in a second drive mode.

A tool for the primary shaping of a housing for a sensor which is designed to capture, via a sensing element, a physical area that is dependent on a variable to be measured, and to emit an electrical output signal on the basis of the captured physical area, including: a mold cavity for receiving a material that molds the housing, and the sensing element, and a box having a wall that bounds the mold cavity, wherein at least a part of the wall that bounds the mold cavity is mounted in a displaceable manner.

An injection molding machine (1) including: a bed (B); an injection device (3) provided to be movable with respect to the bed (B); a mold clamping device (2) provided on the bed (B); and a movement device (5) configured to move the injection device (3), in which the movement device (5) includes a hydraulic cylinder and a hydraulic pump for supplying a working fluid to the hydraulic cylinder, and the hydraulic pump is provided inside the bed (B).

An injection molding device includes a fixing section to which a molding die having a fixed molding die and a movable molding die, an injection section that injects a molding material, and a moving section that moves the injection section relative to the fixed molding die. The injection section includes a nozzle and an injection amount adjustment mechanism. The injection molding device further includes a control section configured to control the moving section, the injection amount adjustment mechanism, and a heater. The control section executes the following in a state where the molding die is mounted on the fixing section, a first control in which the nozzle is brought into contact with the fixed molding die and the molding material is injected, and a second control in which the nozzle is separated from the fixed molding die after a predetermined time elapses from the completion of the first control.
