Abstract

In an injection mold including at least two mold sections which are movable relative to one another for opening and closing the injection mold and an electronic counter with an actuator and a sensor element supplying, influenced by the actuator, a signal indicative of the number of closings of the injection mold, the sensor element is disposed in a first housing and the electronic counter is disposed outside the first housing and connected to the sensor element via an electrical communication line.

Claims

1. An injection mold including at least two mold sections (1, 2) which are movable relative to one another for opening and closing the injection mold, and a counter arrangement including an electronic counter (4a) with an actuator (3a) and a sensor element (3b) supplying under the influence of the actuator (3a) a signal indicative of the number of closing procedures of the injection mold, said sensor element (3b) being disposed in a first housing (3) and the electronic counter (4a) being disposed outside the first housing (3) and connected to the sensor element (3b) via an electrical communication line (5) and a monitoring element (6) for determining an interruption of the connection between the sensor element (3b) and the counter (4a).

2. An injection mold according to claim 1, wherein the actuator (3a) is arranged at the first housing (3).

3. An injection mold according to claim 1, wherein the first housing (3) includes a disassembly sensor (8) for sensing a removal of the first housing (3) from the injection mold.
