Equipped with threaded hole, mandril screws in threaded hole to lock with connector, and mandril drives ejector retainner plate mobile by connector.
Further, the ejector retainner plate includes upper ejector retainner plate and lower ejector retainner plate, and lower ejector retainner plate is equipped with a through-hole, described
Connector is placed in the through-hole of lower ejector retainner plate, and connector has flange, and the flange of connector is stuck in lower ejector retainner plate upper end, upper thimble
Board bottom portion is equipped with the relief hole of the flange of accommodating connector, and upper ejector retainner plate and lower ejector retainner plate are bolted to connection, upper thimble
Plate and lower ejector retainner plate clamp connection.
Further, the threaded hole of the connector is tapped blind hole, and mandril screws in the tapped blind hole, mandril upper end
Abut tapped blind hole inner bottom wall.
The present invention also provides a kind of die castings, including mould ejector plate resetting-mechanism above-mentioned.
Mandril of the invention connects ejector retainner plate, and ejector rod forcibly pulls thimble sheet reset, avoids ejector retainner plate that from cannot resetting in time
Thimble is caused to damage mold.Mandril is detachably connected with fixing seat, and the convenient mold that takes out from equipment is to be replaced.

Specific embodiment
Now in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is the die casting for being equipped with ejector retainner plate resetting-mechanism of the present invention, and Fig. 2 is to place the die casting
Equipment is equipped with ejection cylinder 4 in equipment.
A kind of mould ejector plate resetting-mechanism referring to FIG. 1 to FIG. 4, including mandril 1, fixing seat 2 and bolt 3, mandril
1 connect with ejector retainner plate, and fixing seat 2 is connect with the ejection cylinder 4 in equipment, mandril 1 by bolt 3 realize with fixing seat 2 can
Dismantling connection, ejection cylinder 4 drive mandril 1 to jack up ejector retainner plate or pull thimble sheet reset.In this embodiment, fixing seat 2 passes through
Screw thread locks with ejection cylinder 4, and mandril 1 is locked by screw thread and ejector retainner plate, rotate in a circumferential direction movement and the mandril 1 of fixing seat 2
