Abstract

Improvements in safety devices in a machine for molding by inspection synthetic materials, provided with electrical connection means that, when the mold is not perfectly closed, interrupts the circuit of the control current of the drive of the plates of the mold, characterized in that a first switch is provided in the yoke supporting the second mold plate, which is actuated by a connection member provided in this second mold plate, while a second switch is arranged in the support plate of the first mold plate , which is actuated by a connection member provided in this first mold plate, the first of the switches opening, which is closed when the mold is open, when the second mold plate during the working path of the first mold plate opens. driven is dragged by the latter in a previously determined path, while the second switch, which is open when the mold is likewise, closes the first mold plate has traveled a predetermined path of its working path, and means are provided that interrupt the circuit of the control current when both switches are open for a period of time previously determined.
