ABSTRACT:
An apparatus for sending a plurality of switching signals to a switching device for sequentially switching the position of an injection gate of a injection molding machine is provided. The apparatus is utilized for molding a work piece in a mold during a molding cycle from a first closed position, to a first open position, to second closed position, to a second open position and then to a third closed position. The switching signals are indicative of one of the open position and the closed position. The apparatus is to be hand carried by a machine operator. The apparatus includes a body. The body is hand carriable by a machine operator. The apparatus also includes a first input conduit and a second input conduit. The first input conduit is operably associated with the body for receiving a first switching signal indicative of a desire to switch the position of the injection gate. The second input conduit is operably associated with the body for receiving a second switching signal indicative of a desire to switch the position of the injection gate. The apparatus also includes an output conduit simultaneously operably connected to the first input conduit and to the second input conduit for transmitting one of the first switching signal. The apparatus also includes a first inhibitor and a second inhibitor. The first inhibitor is operably associated with the second input conduit for inhibiting the first switching signal from being transmitted through the second input conduit. The second inhibitor is operably associated with the first input conduit for inhibiting the second switching signal from being transmitted through the first input conduit.
