Abstract
The utility model provides a balanced ejection system of a die. The system comprises an ejector plate and a plurality of oil cylinders, wherein the oil cylinders are connected with the ejector plate through oil cylinder connecting rods, and the top ends of the oil cylinder connecting rods are connected with inserts connected with the ejector plate. Each insert comprises a connecting block connected with the corresponding oil cylinder connecting rod, an insert body and an anti-rotating block, wherein the insert body and the anti-rotating block can extend into and rotate in an insert assembly groove, and a step face on the connecting block is in contact with the ejector plate. When each anti-rotating block rotates in the insert assembly groove till the step face on the anti-rotating block is in contact with that on a step groove, the corresponding insert is fixed with the ejector plate. When each anti-rotating block rotates in the insert assembly groove till the step face on the anti-rotating block is not in contact with that on the step groove, the corresponding insert is pulled out from the insert assembly groove, thereby separating the insert from the ejector plate. The system provided by the utility model has the beneficial effect that the oil cylinders are connected with the ejector plate by the inserts, so that the system is convenient to detach, and the work efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of mould balance ejection system.
Background technology
In existing technology, ejection system is last system of mould, and it is after mould completes injection moulding, cooling, die sinking, dropout.By last procedure from ejecting in mould of product safety balance.The requirement of ejection system is balance, can automatic rollback after ejecting, product is not caused to damage, product energy Automatic-falling.Because the liftout attachment of mould is many, weight is large, frictional force is large, if with adopting convention to use machinery to eject---ejecting power and adding the mode that mounting spring resets of injection machine self can not meet the requirement of this mold at all.First be that balance can not guarantee, machinery ejects the position, several hole of Shi mold center position.Because knock-pin is certainly will will cause situation different in size by external mode, on ejecting balance, just there are a lot of impacts.Next is can not self-return after ejecting, because liftout attachment is many, weight is large, frictional force is large.Spring can not guarantee the requirement of resilience dynamics.
Summary of the invention
The utility model provides a kind of mould balance ejection system, redesign ejects power set-hydraulic jack, oil cylinder connecting rod is not directly arranged on ejector retainner plate, because oil cylinder connecting rod junction is with being threaded, as being directly connected with ejector retainner plate, must be to want long-time screw thread rotation work, and be that each dismounting all needs to take much time dismounting oil cylinder.So must be designed to insert type, connect, by mold insert and oil cylinder connecting rod, first connected, then by another fixedly mold insert this mold insert is fixed on ejector retainner plate, play the requirement of easy accessibility.Concrete technical scheme is: mould balance ejection system, comprise ejector retainner plate and a plurality of oil cylinder, described oil cylinder is connected with described ejector retainner plate by oil cylinder connecting rod, described oil cylinder connecting rod is vertical with described ejector retainner plate plate face, and described oil cylinder is advanced and retreat all the time by ejector retainner plate described in described oil cylinder connecting rod push-and-pull under poised state;
The top of described oil cylinder connecting rod is connected with the mold insert for being connected with described ejector retainner plate, described mold insert comprises the contiguous block being connected with described oil cylinder connecting rod, mold insert body and the Anti-rotary block being connected successively, on described contiguous block, there is stage face with described mold insert body junction, on described Anti-rotary block, with described mold insert body junction, the position that is positioned at described mold insert body both sides has respectively stage face;
The side of described ejector retainner plate has the mold insert fitting recess for being connected with described mold insert, and described mold insert fitting recess is step groove;
Described mold insert body and described Anti-rotary block can stretch into described mold insert fitting recess and rotate in described mold insert fitting recess, and the stage face on described contiguous block contacts with described ejector retainner plate;
When described Anti-rotary block turns to stage face on described Anti-rotary block and step surface on described step groove contacts in described mold insert fitting recess, described mold insert and described ejector retainner plate are fixed, when described Anti-rotary block turns to stage face on described Anti-rotary block and step surface on described step groove does not contact in described mold insert fitting recess, described mold insert can be extracted in described mold insert fitting recess, with this, described mold insert is separated with described ejector retainner plate.
One end that described oil cylinder connecting rod is connected with mold insert has screw thread, on described contiguous block, has screwed hole, and described oil cylinder connecting rod and described contiguous block are threaded connection.
Further, in order to guarantee that oil cylinder, with advance and retreat, can balance eject ejector retainner plate, described a plurality of oil cylinders are fixed on the same plane of B plate below, and described in each, the oil circuit of oil cylinder is isometric.
Further, the needs for ejector retainner plate indeformable and balance when ejecting, comprise four described oil cylinders altogether, and described ejector retainner plate integral body is I shape, and described mold insert is connected in the ear of described I shape ejector retainner plate.
Further, for mold insert for convenience detach, a plurality of holes that turn of described contiguous block surface design.By pole instrument, rotate very easily mold insert, it is dismantled or installed from ejector retainner plate.
Further, the rotation of mold insert when preventing system motion, adopt following technical scheme to solve: when described Anti-rotary block turns to stage face on described Anti-rotary block and step surface on described step groove contacts in described mold insert fitting recess, the side of described Anti-rotary block flushes with the side with the described ejector retainner plate at described mold insert fitting recess place, and the dismountable baffle plate being provided with across described mold insert fitting recess both sides in side of ejector retainner plate is stated in this place.
Further, for preventing oil cylinder connecting rod rotation when working, the outer surface of described oil cylinder connecting rod has a delineation bit plane, dismountable locating piece that is provided with on the face that described contiguous block is connected with described oil cylinder connecting rod, when described locating piece is fixed on described contiguous block, the side of described locating piece contacts with described plane of orientation.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, with oil cylinder as the power ejecting, and design insert type structure as the attaching parts of oil cylinder and ejector retainner plate, make whole ejection system can also meet requirement for convenience detach when meeting balance and ejecting.
