YLFT-3 Prevulcanized Tread Molder

The machine is mainly used to vulcanize slip pre-vulcanized tread. Itis mainly made up of stander,heating plate,movable platform,mould closing mechanism,mould opening mechanism,draw and push mould device,hydraulic system,electrical system and steam pipelines. The stander is interconnected by jaw frame board,chassis,stiffened panel,stiffened plates and draw rod.At the bottom of the framework,the mold closing mechanism is equipped,the mold closing piston cylinder is linked with movableplatform by clip plate.The heat insulating mattresses are fixed between movable platform and lower heating plate as well as between upper heating plate and upper framework. The machine,fixed 5 layers of heating plates can be set 4 layers of molding plates.The 3 mid layers are hung parallelly by guide bolt on both sides and the spacing can be adjusted by nuts.To ensure the mould opening smoothly,two sets of split cylinders are set under the framework and 4 springs are added inside the lead screw on both sides of heating plate. While opening the mould,the heating plate operates up and down,guided by guide bolts at both ends and each heating plate is furnished with the draw and push mould device,after opening the mould,the device can push every layer of molding plate out for 300mm,so as to assemble and unassembled tread rubber as well as replace the checked plate. To get the quick steam exhaust,set the exhaust facility at both ends of the machine.When the exhaust steam needs letting out manually,rotate the valve counterclockwise by hand.After discharging exhaust steam,the valve should be turned strictly clockwise.Then,the steam tripping valve works.All above is to ensure the temperature of heating plate complied with the standards of techniques in the process of vulcanizing. The system of hydraulic pressurestation is consisted of high,mediate and low parts;the low pressure is used for opening molds quickly;the high pressure is used for pressurizing and pressure maintaining and the mediate pressure is used for pushing and drawing molding plate and mould opening. The electric system adopts regular circuit controland operates by button. The system of steam pipelines provides steam to the heating plate and heating molds,which is operated manually and controlled with cut-off valve.(The condensed water are discharged through the draining valve by hand.)
