A hot runner system having a nozzle and a manifold seated against the nozzle. An actuator plate is spaced apart from the manifold by a support pad which surrounds a lower mouth of an actuator bore that extends through the actuator plate. A valve pin extends through the support pad and the manifold to a downstream end of the nozzle. A cylinder is received in the actuator bore from a rearward side of the actuator plate and a piston coupled to the valve pin is received in the cylinder from a forward end of the cylinder.

An injection molding apparatus including a stack mold tool and a ball screw centering device. The stack mold tool including a stationary mold block, a center mold block movable relative to the stationary mold block, and a distal mold block movable relative to the center mold block. The ball screw centering device includes a center bearing housing connected to the center mold block, a rotatable shaft having a first side ball track and a second side ball track, a first nut coupled to the stationary mold block, the first nut including a track portion cooperating with the first side ball track to define a passage for a first set of ball bearings, and a second nut coupled to the distal mold block, the first nut including a track portion cooperating with the second side ball track to define a passage for a second set of ball bearings.

A filling device for the joint that provides filling of the desired area to be poured in cases where similar electrical transmission systems or components such as low and high voltage busbars and cables are attached to each other.

An injection molding system includes: an injection molding machine where a shaping mold is installed; a material supply device supplying a material to the injection molding machine; a temperature controller controlling a temperature of the shaping mold; a dryer drying a material stored in the material supply device; a controller controlling the injection molding machine; and a casing. The injection molding machine, the material supply device, the temperature controller, the dryer, and the controller are provided inside the casing. The casing has a caster and is configured to be movable.

An injection molding system includes a main unit in which a first injection molding machine that injects a first molding material and molds a molded article is disposed and a control unit separated from the main unit and configured to control the first injection molding machine. The control unit is coupled to the main unit via a connection cable having predetermined length.

Injection molding machine comprising at least one first and one second injection unit having a chamber for injecting a plasticized molding material and a piston for advancing a predetermined amount of plasticized molding material along a first axis from the chamber into a cavity of a mold, the machine including a form tool comprised of at least a first tool portion and a second tool portion, a tool cavity being at least partially disposed in the first tool portion.

A protective cover for a plasticising cylinder of a shaping machinehas an elongate internal space which is enclosed by at least one wall and in which the plasticising cylinder can be arranged. A terminal box for heating strips arranged on the plasticising cylinder projects into the internal space, and one of the walls of the protective cover has an opening which is closed by an openable cover member. In the opened condition, the opening allows access to the terminal box or the interior of the terminal box.

A mold apparatus for molding a rotating member includes: a column mold portion including a first column molding hole extending in a first direction and configured to mold a column portion therein and a first blade molding groove formed as an intaglio on an inner circumferential surface of the first column molding hole to have a shape corresponding to a blade and configured to mold the blade therein, and an extraction guide configured to push a first end of the column portion in the first direction to thereby extract the column portion from the first column molding hole, at least a portion of the extraction guide being positioned inside the first column molding hole. The extraction guide is configured to press the column portion to thereby extract the column portion from the first column molding hole while the column portion rotates in an inclined direction of the blade.

An injection molding machine includes: a mold clamping unit; an injection unit; and a safety cover that surrounds the mold clamping unit and the injection unit. The safety cover includes a detachable panel that is attached to an opening. The safety cover includes a door portion that moves between a position where the door portion blocks a second portion of the opening and a position where the door portion does not cover the opening. The safety cover has a size that is smaller than the opening but greater than the second portion. A detachable panel has a first stopper that restricts an opening motion of the door portion when only the second portion is open. The safety cover is provided with a second stopper that restricts the opening motion of the door portion when the opening is entirely open and the detachable panel is removed.

A hot runner system having a nozzle and a manifold seated against the nozzle. An actuator plate is spaced apart from the manifold by a support pad which surrounds a lower mouth of an actuator bore that extends through the actuator plate. A valve pin extends through the support pad and the manifold to a downstream end of the nozzle. A cylinder is received in the actuator bore from a rearward side of the actuator plate and a piston coupled to the valve pin is received in the cylinder from a forward end of the cylinder.
