Description
Technical field
Present invention is generally directed to a kind of locking device on the crossbeam of at least two difference location that end plate or mold cramping plate are locked in injection (mo(u)lding) machine by least two clip element, described clip element is respectively configured in the crossbeam to difference location, and respectively has at least two half-shell.
Background technology
Therefore the present invention is exactly that end plate (or clamping plate) clamping can be maintained on the crossbeam of injection (mo(u)lding) machine by this locking device in other words about a kind of locking device.To this, for many years known various different locking device.
Such as, JP2989116 illustrates a kind of locking device with hydraulically powered lift cylinders, and this lift cylinders makes the half-shell translational motion of two clip elements.
EP1238777B1 achieves the synchronization of each clip element of locking device in a very similar way.But at this, each half-shell is by mean of a rotating mechanism and is connected.Wherein, only in only one half-shell, realize driven in translation, and be delivered in other half-shell by corresponding rod member or connecting mechanism for rotating.
Knowing locking device from AT003639U1, in this locking device, the half-shell of different clip elements is pressed off each other by the driving device of hydraulic pressure, or is drawn together.This driver element with make the rocking arm (waiting armed lever) of synchronized movement of top clip element and bottom clip element and be not directly contacted with.Specifically, this rocking arm is to can be rotated to support on a bearing pin, and wherein, this bearing pin is fixing with movable mold cramping plate to be connected.Connection between top half-shell and bottom half-shell is therefore only and realize either directly through a piston rod that may move into and remove.
Additionally, JP3927066 illustrates for making all four synchronized locking device of clip element, wherein have employed again the piston rod that fluid pressure type may move into and removes.
With these documents so far quoted from the difference is that, the present invention be more particularly directed to a kind of locking device on the crossbeam of at least two difference location that end plate or mold cramping plate are locked in injection (mo(u)lding) machine by least two clip element, described clip element is respectively configured in the crossbeam to described different location, and it is respectively provided with at least two half-shell, wherein, the at least two half-shell being allocated to different clip elements is hinged respectively through rod member and a common synchronous element, and, two rod members are connected by cradle head with described common synchronous element with corresponding half-shell and another aspect on the one hand.
The locking device of this composition preamble of the present invention such as draws from JP6154989, and wherein, by the translational motion of a piston, two rod members are rotatable so that the half-shell of two different clip elements from or move toward one another.At this disadvantageously, the driver element distance locking device for piston compares farther out.Additionally, the return movement of translation needs to spend relatively large power after reaching maximum position dead point in other words.
For equally constituting the EP2163370A1 of preamble of the present invention, being also such, wherein, be make synchronous element move at lateral translation equally, this rod member moving through lateral engagement and corresponding cradle head are delivered to the half-shell of variant clip element.Particularly, synchronous element be realization be synchronized with the movement needs relatively large number of space because always needing the locational space for performing stroke.
Summary of the invention
