<p>It incorporates a push rod (1) which is pushed mechanically by an ejector plate or other means of the injection mould in each injection process. The push rod (1) moves in a linear direction a link (4) attached to a central cylinder (5) which it turns inside wheels (3), provided on their outer face with marking digits, which have an inner toothing, on which pressure is exerted by a comb (6), made up of teeth, that protrudes externally from the central cylinder (5) in order to change the position of the wheel (3) in the forward direction of the central cylinder (5), and the digit displayed, while also incorporating magnets (7), matching up with the outer face of the wheel (3), which assist in securing the position of the comb (6), thereby preventing the wheel (3) from turning while the cylinder (5) is sliding back.</p> |
