Abstract
An injection mold comprising a fixed and a movable mold half and a demolding device for the moldings, which essentially consists of grippers and a kinematic chain, by means of which the opening movement of the mold half is transferable to the holders of the grippers. By this means, the opening movement of the mold half can cause the grippers to move towards the moldings to be taken out of the mold half.
Claims4
An injection mold comprising a fixed and a movable mold half and a demolding device for the moldings which is connected to the movable mold half and which consists of one or more grippers guided in a pair of rails by means of a holder plate, a mounting plate for the pair of rails, a pinion which is rotatably held on the mounting plate and can roll on a rack which can be firmly connected to the fixed mold half or to the mounting plate, and a kinematic chain which converts the rotary movement of the pinion into a rectilinear movement of the holder plate for the grippers, wherein, in order to form the kinematic chain, the pinion is connected to a crank and the latter in turn is connected, via a hinged connecting rod, with an oscillating crank constructed as a rack for driving a further pinion, and the shaft of this pinion is coupled to a chain drive, to whose transport chain is fixed the holder plate for the grippers.
