The invention also relates to an injection machine having the die assembly unit.
Description
Technical field
The present invention relates to a kind of closing unit of injection machine.
Background technology
Due to the high mold clamping force that needs to reach in injection machine, often advantageously, respectively in order to make movable mold clamp board (fast travel portion) rapid movement and in order to form mold clamping force (pressure stroke), drive unit to be set.It is important in this that, before forming mold clamping force, lock, this is because fast travel device is not designed to bear described high mold clamping force.Described locking realizes via being fixed on lock nut on end plate or that be fixed on movable mold clamp board mostly.At this, the interior profile in lock nut and the outline acting in conjunction on the cylinder of closing unit and therefore prevent described cylinder with respect to the motion of lock nut and prevent from being thus fixed on plate on described cylinder with respect to the motion of lock nut.
For this lock nut, by prior art, substantially there are two kinds of makes.In a kind of make, use Separated nut, the two half-unit of described Separated nut is combined with separated from one another so that the locking and unlocking cylinder.In another kind of make, interior profile and outline all do not extend on the whole side face of cylinder or on the inner side of nut.For release, nut is rotated in the following manner at this, threaded portion not in engagement in, thereby cylinder can be moved.
The shortcoming of these two kinds of makes is, in the movable mold clamp board lock motion that must carry out nut between with mineralization pressure and mineralization pressure itself in place.This is to cycle time and therefore finally productivity ratio is produced to adverse influence.
Summary of the invention
The closing unit that the object of this invention is to provide a kind of injection machine, this closing unit can be realized the cycle time that relative prior art shortens.
This object realizes by a kind of closing unit.
Its mode is, nut is configured to screw thread in intermeshing, self-locking all the time by rotatably mounted and outline and interior profile.
In order to make cylinder motion, nut can easily be rotated.Yet, by thread structure being become to self-locking, prevent that cylinder from moving during forming mold clamping force.
For the present invention, pressing mechanism whether with hydraulic pressure or electronic or arbitrarily other modes form unimportant.
In thering is the closing unit of end plate, by nut be can be rotated to support on end plate, can especially easily realize locking.Avoid thus the space problem producing may be on being fixed on movable mold clamp board time, this is because for example mould or ejector may be arranged on described movable mold clamp board.Even so, nut be can be rotated to support on movable mold clamp board and also can be expected.
In order to control exactly or adjust especially the motion of movable mold clamp board, can set, quick traverse mechanism has electronic drive unit.
In order to ensure fast and open and close closing unit trouble-freely, can be provided with synchronous guiding device, described synchronous guiding device is by the axle of drive unit and nut motion coupling in locking manner.
Especially simply, this synchronous guiding device can be designed to belt driver.
In order to ensure locking well enough, can be provided with for stoping the brake apparatus rotatablely moving of nut.Described brake apparatus just can for example be activated and guarantee can not occur the creep campaign of less desirable nut during mold clamping force forms.
The present invention is claimed a kind of injection machine having according to closing unit of the present invention also.
Accompanying drawing explanation
Other advantages of the present invention and details provide by accompanying drawing and relevant accompanying drawing explanation.This illustrate:
Fig. 1 has the injection machine according to closing unit of the present invention,
Fig. 2 a is according to the zoomed-in view of locking device of the present invention, and
Fig. 2 b pressing mechanism is arranged on the another kind of embodiment in end plate.
The specific embodiment
Fig. 1 illustrates a kind of injection machine 20, and this injection machine has frame 16, fixing mold clamp board 15, movable mold clamp board 9 and the injection device 14 schematically showing.Pressing mechanism 2 is arranged on movable mold clamp board 9 in this embodiment.Closing unit 1 has end plate 7.In order to make movable mold clamp board 9 rapid movements, be provided with quick traverse mechanism 8.Described quick traverse mechanism has screw actuator 11 and electronic drive unit 10.In the present embodiment, drive unit 10 is designed to hollow shaft driving device, and its axle 13 is used as the nut of screw actuator 11 simultaneously.
Cylinder 3 has outline 4 and is fixed on movable mold clamp board 9.End plate 7 is only schematically illustrated, thereby can see the lock nut 6 being embedded in this end plate.Lock nut 6 has interior profile 5(and sees Fig. 2 a), described interior profile be configured to externally threaded outline 4 actings in conjunction.At this, lead is chosen to, and makes to produce self-locking effect in the situation that forming mold clamping force.
Be provided with in addition synchronous guiding device 12, described synchronous guiding device is by the coupling in locking manner of doing exercises of the motion of axle 13 and nut 6.In this embodiment, synchronous guiding device 12 is designed to belt driver.
Fig. 2 a is the detailed view of the embodiment in Fig. 1.In this partial view, can see the interior profile 5 of nut 6.Every other Reference numeral is corresponding to the Reference numeral in Fig. 1.
This is also applicable to illustrate Fig. 2 b of another kind of embodiment of the present invention.At this, pressing mechanism 2 is arranged in the end plate 7 being shown specifically.Synchronous guiding device 12 this be configured to allow small, because forming the motion of the lock nut 6 that mold clamping force produces.
The present invention is not limited at the embodiment shown in this.For example the present invention can be used in vertical type without difficulty.Belt driver is not also definitely essential.Synchronous guiding device 12 can for example also be designed to two synchronous, electronic drive units that are positioned on common axle.
