Detailed description of the invention
Illustrate in fig 1 a: gradient and the plate depth of parallelism that in closing unit 1, how can adjust by the executing agency 2 of a kind of temperature adjustment of outfit or control fixed mould clamping plate 5.These fixed mould clamping plate 5 are bearing in frame 7 by supporting device 9 in upside.In the downside of fixed mould clamping plate 5, rod 6 is used for being supported in frame 7.By carrying out temperature adjustment by electric heater unit 8, the length of rod 6 can change, and just makes the gradient of fixed mould clamping plate 5 occur thus.Specifically, an adjusting device 3 is provided with in this case.This adjusting device is connected with the unshowned temperature sensor be positioned on rod 6 and heater.
Now, the top view of the injection (mo(u)lding) machine 10 with closing unit 1 of the present invention is shown in Figure 1b.At this, each Reference numeral is corresponding with the situation in Fig. 1 a.Show moveable die clamping plate 4 in addition.
Fig. 1 c shows the top view of the supporting device of fixed mould clamping plate 5.First can see at this, frame 7 is made up of two side plates (curb girder) 16 and a transverse slat (crossbeam) 17 in this region.The unshowned here supporting device 9 of fixed mould clamping plate 5 is positioned on side plate 16.Fixed mould clamping plate 5 support and are resisted against on transverse slat 17 by rod 6.
For clarity sake, the frame 7 of horizontal closing unit 1 is illustrate only in fig. 2 a with side view.So substantially, the side plate 16 of frame 7 can be seen.At this, fixed mould clamping plate 5 are installed in the end of upper right quarter in the view, and on the end of view upper left quarter, has support moveable die clamping plate 4, such as, by means of elbow-bar mechanism.Two temperature adjustment passages 11 are provided with in order to control the size of frame 7.Described temperature adjustment passage 13 to realize by holing, and these borings 13 are sealed partially by embolism 14.In this way, the tortuous coiled structure of temperature adjustment passage 11 also can be realized with relatively less cost.Two temperature adjustment passages 11 together form each closed-loop path respectively with pump 12.Be provided with heat exchanger 15 in addition.Pump is connected with control device 3 in this embodiment.Whereby, the delivered volume of temperature control medium is undertaken controlling by temperature adjustment passage 11 and thus the degree of control temperature adjustment itself and scope.
Show the accompanying drawing similar with Fig. 2 a in figure 2b, wherein the design of temperature adjustment pipeline 11 is different.Now, for clarity sake, pump 12, heat exchanger 15 are not shown in the accompanying drawings yet and lead to the transfer pipeline in temperature adjustment loop 11.
By the form of implementation of Fig. 2 a or Fig. 2 b, not only can adjust or the control panel depth of parallelism, and can control or adjust the torsion of frame 7 along its machine axis.The possibility of result of this torsion will be mold clamp board 7 using machine axis as rotating shaft deflection relative to each other.And the plate depth of parallelism also can be affected due to this torsion.This point can be prevented by following manner according to the present invention: two side plates 16 are so tempered, and what they were always consistent takes dimensions and constant relative position.
Form of implementation shown in Fig. 3 a and 3b relates to a kind of horizontal closing unit 1 with four temperature adjustment crossbeams 16.By this side direction view, two in four crossbeams 16 can only be seen in fig. 3 a.Be only that crossbeam 16 being in top in the view illustrates with being broken away, therefore see temperature adjustment pipeline 11 thereunto only.But all four crossbeams are configured with temperature adjustment pipeline 11 in this form of implementation.
In addition, pump 12 is not shown in fig. 3 a and controls or adjusting device 3.These parts/parts can be implemented similarly with Fig. 2 a.
Definitely being configured in thin portion view 3b of temperature adjustment pipeline 11 can be seen.Temperature control medium can be delivered to always the end of boring 18 by the pipe 17 be arranged in boring 18.Because this pipe 17 is not inserted in boring 18 completely, again because the external diameter of this pipe is less than the internal diameter of boring, therefore the temperature control medium of this pipe 17 outside can turn back to again the opening of boring 18.Temperature control medium inflow or flow direction when flowing out temperature adjustment pipeline 11 are represented to have similar temperature in fig. 3 a respectively by arrow.
Here shown different forms of implementation can certainly be combined, that is, such as following situation is beyond doubt feasible: not only adopt the rod 6 that heated in order to supporting and fixing mold clamp board 5 but also adopt temperature adjustment pipeline 11 in order to carry out temperature adjustment to frame 7.
The present invention is not limited to shown embodiment here.Such as be easy to it is envisioned that: adopt temperature adjustment executing agency in order to carry out temperature adjustment to toggle link.
