Description
Affiliated technical field
The present invention relates to a kind of hydraulic lock mold mechanism of swelling cohesion style.
Background technology
Traditional hydraulic lock mold mechanism can be divided into vertical compression type mould-locking mechanism and band brake type clamping mechanism; The shortcoming of vertical compression type mould-locking mechanism: because rapid mould-moving and high-voltage lock mould are all realized by four Mode-locking oil cylinders, make shifting formwork speed slack-off because the exchange of a large amount of hydraulic oil takes place when rapid mould-moving, the mould power that rises that injection causes is compressed the long stroke fluid of Mode-locking oil cylinder and causes allowing mould; The shortcoming of band brake type clamping mechanism: accurately the band-type brake action is complicated and consuming time, hold repeatedly band-type brake can occur on the lock and pull bar on the mechanical wear of tooth, the pull bar tooth of getting on the bus reduces the intensity of pull bar.
Summary of the invention
Technical problem to be solved by this invention: the hydraulic lock mold mechanism that a kind of swelling cohesion style is provided; this mechanism is according to inclined plane principle; adopt hydraulic thrust to make between the interior ring of swelling skewback and the pull bar and produce the huge power of holding tightly; realize that moment plays high pressure and hold pull bar tightly and play high pressure and produce clamp force, finish quick accurate and reliable locked mode.
The present invention solves the technical scheme that its technical problem adopts: a kind of hydraulic lock mold mechanism of swelling cohesion style, and it comprises the pull bar pressing plate, pull-rod nut, the pull bar bridge screw, pull bar, mould shifting oil cylinder, solid plate, mould, moving platen, swelling obvolvent oil cylinder pull bar, fairlead, the swelling supporting seat, supporter, pull-type screw, the swelling skewback, the compression spring, swelling obvolvent oil cylinder bonnet, swelling obvolvent oil cylinder piston bar, swelling obvolvent cylinder body, swelling obvolvent oil cylinder protecgulum, high-voltage lock mould oil cylinder piston bar, high-voltage lock mould oil cylinder bonnet, the high-voltage lock mould cylinder body, high-voltage lock mould oil cylinder pull bar, high-voltage lock mould oil cylinder protecgulum; By the pull bar pressing plate, pull-rod nut, the pull bar bridge screw, pull bar, after the solid plate assembling pull bar and a plate are completely fixed, the swelling supporting seat, supporter, pull-type screw, the swelling skewback, the compression spring, swelling obvolvent oil cylinder bonnet, swelling obvolvent oil cylinder piston bar, swelling obvolvent cylinder body, swelling obvolvent oil cylinder protecgulum forms swelling obvolvent cylinder component by swelling obvolvent oil cylinder pull bar assembling back, high-voltage lock mould oil cylinder piston bar, high-voltage lock mould oil cylinder bonnet, the high-voltage lock mould cylinder body, high-voltage lock mould oil cylinder protecgulum assembling back is installed in by high-voltage lock mould oil cylinder pull bar on the left side at four angles of moving platen and forms the high-voltage lock mould oil cylinder, the left side of swelling supporting seat and high-voltage lock mould oil cylinder piston bar forms a fixed connection, and moving platen can form slide-and-guide with pull bar by fairlead and contact; Can realize rapid mould-moving by mould shifting oil cylinder; Mould closes up the back can realize that by swelling obvolvent cylinder component moment plays high pressure and hold pull bar tightly, plays high pressure by high-voltage lock mould oil cylinder moment again and obtains clamp force.
Beneficial effect of the present invention:
1. close up at mould and can realize under the state holding pull bar fast tightly and obtaining high-voltage lock mould power, also can realize unclamping fast with the obvolvent of pull bar and realize the high speed shifting formwork, thereby obtain the ultrashort mould circulation timei of unblanking.
2. so long as mould closes up state just can directly play pressure and hold pull bar tightly and obtain clamp force, because be no screw thread obvolvent, need not to look for the position obvolvent, so need not any obvolvent precision just can finish reliably and hold tightly, the required precision of control system also decreases, the complete machine cost reduces, and the stability of complete machine and reliability improve.
3. the position of holding tightly of pull bar need not to be provided with screw thread, and effectively tension lifting surface area maximum can be born bigger clamp force.
4. the high pressure chest inner fluid thickness of high-voltage lock mould oil cylinder is little, and the fluid decrement is few, and whole clamping mechanism rigidity is higher.
