In a tire mold press having a steam dome defining a chamber in which steam applies heat to the exterior of a tire mold, condensate which accumulates in the top center plate is simply and effectively removed after the end of the curing cycle and before the mold is opened by a passage through the top center plate controlled by a valve opened in response to a reduction of pressure acting on the lower surface of the plate as the tire cavity is emptied. The costs and hazards of removal of condensate or of operating and maintaining siphons are avoided. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description. |
