Description
Technical field
The present invention relates to die casting machine technical fields, specifically a kind of that Mode-locking oil cylinder is used to carry out mode locking to remove toggle
Structure is molded casting machine without In A Diecasting Equipment fast lock.
Background technique
Toggle structure die casting machine is present existing most of die casting machines, and it is straight with closing cylinder that the die casting machine of this structure, which has,
Connect the crosshead for pushing toggle structure, be moved along by toggle mechanism urges moving template, it is current after brace in straight line,
Toggle mechanism reaches its dead-centre position, and toggle mechanism can amplify the thrust of closing cylinder, to make moving template and quiet template lock
It can achieve the clamp force of needs when mould.But this mechanism have a defect be toggle connection position be by big small clevis pin with head
Connection, toggle hole is provided with steel bushing, because big pin shaft stress is bigger, and has certain abrasion during moving, and
It is that a position stress is bigger that axle sleeve moves every time, more exacerbates the abrasion of axle sleeve in this way.After having certain abrasion, just
Ideal mode locking effect cannot be reached, be easy to cause casting flaw.There are one it is more troublesome be this structure mold exchange
When more troublesome, mold exchange again to readjust the position of molding cylinder seat since the thickness of mold is different, to reach
The clamp force needed needs continuous fine tuning.
Summary of the invention
Mode-locking oil cylinder is used to carry out mode locking to go in response to the problems existing in the prior art, the purpose of the present invention is to provide a kind of
