Arrangement for pressurizing a plurality of molds with one or more pressurized fluids for molding synthetic materials and maintaining said materials at a predetermined temperature in the molds

摘要

An arrangement for charging a plurality of molds for processing plastic materials with at least two sources of fluid and for temperature regulating the molds. Each mold of the arrangement is provided with a feed inlet conduit to which a three-way valve is connected. The feed inlet conduit is also connected to the two sources of fluid and each mold further includes an outlet conduit with a thermostat valve. A distribution element is connected to the feed inlet conduit and to the two sources of fluid. The three-way valve is connected to least two sources of fluid. This three-way valve has an outlet which is connected to the distribution element. A heating element is connected in each inlet conduit of each mold. A temperature regulator is mounted in each outlet of each mold for each heating element. This temperature regulator is coacts with the thermostat valve which is mounted downstream of each temperature regulator in each outlet conduit of each mold. A second three- way valve is connected, on the one hand, to the first three- way valve and, on the other hand, to the distribution element.
