Abstract

PURPOSE:To make possible automatically to mount to or demount from a mold a movable plate and a fixed plate, by connecting a nozzle provided vertically to the fixed plate and an end nozzle of a heating cylinder through a hot runner nozzle, and bonding the tip of the nozzle by a leaf spring. CONSTITUTION:The movable plate 5 is elevated by driving a clamping cylinder 3 to a position where the mold can be inserted, and with click 29a of a click support 29 withdrawn, the mold placed on a conveyor 34 is moved to be placed on a lifting conveyor 32 floated from a pair of grooves 31 provided in the fixed plate 7, and the sprue of the mold and the nozzle 16 are moved to be registered. At this time, the nozzle 16 floated a little from the upper surface of the fixed plate 7 is brought in firm contact with the sprue section of the mold by the action of the leaf spring 17. With this state, the clicks 29a, 30a of the click supports 29, 30 are advanced to be secured to the movable plate 5 and the fixed plate 7 respectively.

DETAILED DESCRIPTION OF THE INVENTION In an injection molding machine, a mold is automatically attached to and detached from a movable platen and a fixed platen in order to save working time. The present invention simplifies the problems described below when automatically attaching and detaching a mold in a vertical mold clamping device in which the mold moves in the vertical direction, by separating and adhering the mold and a nozzle for injecting molten resin. The problem was solved by a mechanism. Generally, in a vertical mold clamping device, an injection nozzle is adhered to the upper side of the mold or to the parting surface of the mold. The former requires the injection device to be perpendicular to the mold, which increases the height of a large machine and poses problems in terms of stability. Since the latter method injects the resin from the parting surface of the mold, its range of use is limited by the shape of the molded product. One aspect of the present invention is a vertical mold clamping device that opens and closes a mold vertically, and injects molten resin perpendicularly to the parting surface of the mold to facilitate adhesion between the mold and the nozzle. A device is disclosed in which, when the device is moved from the mold clamping device for nozzle touching, the resin passage on the mold clamping device side is disconnected in conjunction with the movement of the nozzle shutoff pulp on the injection device side.
