A purge cover for injection molding machine has a cover body having a nozzle through-hole allowing a nozzle of a cylinder to pierce through, an exhaust passage extending higher than the cylinder in an upward direction, and a discharge port communicating with the exhaust passage, and a plurality of exhaust plates disposed at the discharge port of the cover body. The plurality of exhaust plates have exhaust holes for air moving in the upward direction from the cover body, and the exhaust holes are arranged so as not to planarly overlap when the plurality of exhaust plates are disposed at the discharge port of the cover body.

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 machine includes a safety door and a guide for slidably guiding the safety door in a direction of opening and closing a mold of the injection molding machine. The guide includes: a first guide part fixed to a machine base of the injection molding machine; a second guide part arranged on the safety door's closing direction side of the first guide part and configured to be removable from the machine base; and a coupling configured to connect the first guide part and the second guide part so that the second guide part can be moved onto the first guide part.

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

An injection moulding machine comprising a fixed tool clamping plate, a movable tool clamping plate and a protection device comprising lateral frame elements or lateral covers, wherein the clamping plates are arranged between the lateral frame elements or the lateral covers and the movable tool clamping plate can travel along a closing axis which runs parallel to the lateral frame elements or the lateral covers in relation to the fixed tool clamping plate, wherein the protection device further comprises first cover elements arranged on the top side of the machine, both on an operator side and on the operator opposite side, which first cover elements extend parallel to the closing axis, the first cover elements being configured for a radial movement, and wherein the protection device further comprises second cover elements on the top side of the machine which extend perpendicularly to the closing axis, wherein the second cover elements being configured for radial movement.

A safety cover (20) for a mold clamping device that surrounds the mold clamping device (10) of an injection molding machine. The safety cover (20) includes a support frame (21) attached to the mold clamping device (10), a safety door (23), and a connecting mechanism (40) that connects an upper portion of the safety door (23) to the support frame (21). The connecting mechanism (40) includes a first rail (41) on the support frame (21), a second rail (42) on the safety door (23), and an intermediate plate (45) arranged between the first rail (41) and the second rail (42).
