An injection molding machine includes a connection member that connects a nozzle touch mechanism and a fixed platen. The connection member has: an arm part that rises upward from a support frame part on a side of the fixed platen; and a platen connection part that is provided on an upper section of the arm part and serves as a second connection section connected to the fixed platen. The platen connection part has: a connection pin that is fixed to the arm part and extends in a left-right direction coinciding with the width direction of a machine frame; and a rotary member that is fixed to the fixed platen and can rotate around the connection pin, wherein the connection pin is disposed so as to pass through the center axis of a nozzle and include a plane parallel to a mount surface of the machine frame.

An injection molding machine includes a sub injection device configured to inject molten resin into a mold of a clamping device along a direction perpendicular to an opening/closing direction of the mold, a sub machine base configured to support the sub injection device, and a coupling unit provided on a main machine base configured to support a main injection device and the clamping device and couple the main machine base and the sub machine base together. The coupling unit includes a base provided on the main machine base, two fixed blocks fixed to the base, a guide bar bridged in parallel to the opening/closing direction of the mold by the two fixed blocks, and a movable block slidably fitted onto the guide bar. The movable block is connected to the sub machine base.

A mounting stand for an injection molding machine has a base member and an erecting member, to which an injection apparatus is attached, vertically arranged on the base member, and is movable with respect to a support supporting the base member. The mounting stand includes a base member protruding portion provided upward from the base member around a portion at which the base member comes into contact with the erecting member, and an anchored portion at which a side surface of the base member protruding portion is anchored to a side surface of the erecting member.

An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting 5 plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

A method of manufacturing an article using injection molding includes a step of injecting resin from an injection nozzle having a valve pin via a resin flow path in a first mold (metal mold) into a cavity in the first mold, a step of inserting the valve pin into the resin flow path, extracting the valve pin from the resin flow path, starting to increase a distance between the injection nozzle and the first mold after extracting the valve pin, and a third step of, after starting to increase the distance between the injection nozzle and the first mold, injecting resin from the injection nozzle via a resin flow path in a second mold into a cavity in the second mold.

An injection molding machine that contributes to improving the quality of a workpiece is provided. An injection molding machine configured to causes torpedo pistons to be slid in one way to thereby plasticize a resin material supplied to a first space of a cylinder, and causes a molten resin to flow into a second space of the cylinder and causes the torpedo pistons to be slid in the other way to thereby inject the molten resin. The injection molding machine includes pressurizing pistons inserted into the torpedo pistons so that the pressurizing pistons can be slid in such a way that an amount of protrusion of the cylinder into the second space of the cylinder with respect to the torpedo pistons is changed, and energizing means for energizing the pressurizing pistons toward the second space of the cylinder.

An injection molding module for performing a series of injection molding actions, includes a robotic system. The molding module in addition includes a series of anchoring members for fixing at least a portion of the robotic system at each location where an injection molding action takes place.

An injection molding machine according to one embodiment includes a bed, an injection apparatus and a moving apparatus provided on the bed, and a hydraulic system for actuating the injection apparatus and the moving apparatus. The hydraulic system is provided with a hydraulic device group including a motor, a hydraulic pump, an oil tank, oil filters, and valves, and the hydraulic device group is arranged inside the bed.
