As shown from the above technical solution, the present invention is fixed on mould the downside of base plate, and base plate can rotate in horizontal plane around the jointed shaft between base plate and the slide block under the effect of the switching mechanism on the hydraulic press, and the patrix development of complicated difficulty changes convenient and simple counterdie development into thereby make originally.From the above, the present invention has improved the mould accuracy of manufacture greatly, has shortened die manufacturing cycle, has improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model switching process;
Fig. 3 is the structural representation after the utility model upset.
The specific embodiment
Shown in Fig. 1～3, a kind of hydraulic press mould inversion set, the lower end of slide block 10 moving up and down is set with base plate 20, one end and the slide block 10 of base plate 20 are hinged, when hydraulic press is in the operating position, mould 30 is fixed on the downside of described base plate 20, is fixed on switching mechanism on the hydraulic press and makes base plate 20 be in level or around its jointed shaft rotation two states.
Described base plate 20 is in level or around its jointed shaft rotation two states, promptly base plate 20 is in level when work, can also be that the upper and lower plates face of base plate 20 can reverse mutually, shown in Fig. 1,3 from 180 ° of original level state turnovers again simultaneously.
It is for the ease of mould 30 is processed that base plate 20 can rotate around jointed shaft, also is to a kind of processing preparation of mould before hydraulic press is started working.After mould 30 disposes, return back to the downside of base plate 20 again, this moment, hydraulic press can formally be started working.
Described switching mechanism has multiple implementation, such as adopting the driven by motor jointed shaft, jointed shaft is fixedlyed connected with base plate 20, thus when motor rotates, just can drive base plate 20 and rotate around jointed shaft.
As preferred version of the present invention, shown in Fig. 1～3, described switching mechanism is the hydraulic cylinder 40 that is fixed on the slide block 10, the bearing of trend of the axis of hydraulic cylinder 40 is identical with the direction that slide block 10 moves, described hydraulic cylinder 40 can rotate around its bearing, the lower end of the piston rod 41 of hydraulic cylinder 40 is provided with the ringent crotch 42 that links to each other with the upper surface of base plate 20, the opening of crotch 42 is towards the direction of base plate 20 rotations, the downside of base plate 20 is provided with bearing 50, bearing 50 is provided with the guide rail that slides therein of upper surface of guiding base plate 20, and described hydraulic press is provided with and limits the limit switch 60 that slide block 10 moves down after base plate 20 is finished flip horizontal.
For following fixed base plate 20 better in working order, described base plate 20 with respect to being provided with the retaining mechanism that base plate 20 and slide block 10 are fixed together with the hinged end of slide block 10.This retaining mechanism has multiple implementation, can be referring to prior art.
In the real work, at first be that staff's control system is to hydraulic cylinder 40 fuel feeding, open retaining mechanism simultaneously, upper face one side and the slide block 10 of base plate 20 are broken away from, base plate 20 is that the center begins rotation with the jointed shaft under the effect of the piston rod 41 of hydraulic cylinder 40 immediately, after the anglec of rotation surpasses 90 °, the upper surface of base plate 20 contacts with the guide rail of bearing 50, this moment, slide block 10 continued to move down, slide block 10 drives base plate 20 and slides at the guiding lower edge of guide rail bearing 50, as shown in Figure 2, because the opening of crotch 42 is towards the direction of base plate 20 rotations, so crotch 42 breaks away from mutually with base plate 20, at this moment the reverse fuel feeding of hydraulic cylinder 40, make the piston rod 41 of hydraulic cylinder 40 return to the home position, slide block 10 continues to move downward, and move to hydraulic press on limit switch 60 touch mutually and stop, as shown in Figure 3, finally finish base plate 20 thus and drive 180 ° of mould 30 upsets, the feasible mode of operation that changes counterdie into for the finishing and the bedding-in of mould 30.
Described base plate 20 is provided with the roller 21 that matches with guide rail with bearing 50 contacted ends.
The setting of roller 21 is convenient to base plate 20 more and is matched with bearing 50, helps the smooth realization of switching process of the present invention.
Shown in Fig. 1～3, the cylinder body of described hydraulic cylinder 40 is provided with the back-moving spring 43 that is connected with slide block 10.
Being provided with of back-moving spring 43 is beneficial to hydraulic cylinder 40 and successfully is returned to initial position, further guaranteed the steady operation of hydraulic cylinder 40.
The quantity of hydraulic cylinder 40 can be set to single, also can be set to a plurality ofly, and as preferred version of the present invention, described hydraulic cylinder 40 is set to two.
What two hydraulic cylinders 40 helped overturning carries out smoothly, and system's structure is comparatively simple, and operating cost is less.
Described slide block 10 is provided with the limited block 11 that stops hydraulic cylinder 40 to rotate around its bearing, and the position of limited block 11 makes hydraulic cylinder 40 drive angle that base plates 20 rotate around jointed shaft to be convenient to base plate 20 slip that matches with bearing 50.
When hydraulic cylinder 40 drives base plate 20 when jointed shaft rotates, base plate 20 is to be rotated under the acting in conjunction of slide block 10 and hydraulic cylinder 40, after the anglec of rotation of base plate 20 surpasses 90 °, the upper surface of base plate 20 just can contact with the guide rail of bearing 50, base plate 20 promptly continues rotation under the double action of slide block 10 and bearing 50 then, this shows, the anglec of rotation of hydraulic cylinder 40 needn't be excessive, as long as above 90 °, and make the upper surface of base plate 20 to contact to get final product with the guide rail of bearing 50, the setting of limited block 11 has stoped the excessive rotation of hydraulic cylinder 40 effectively, has both saved the energy, has prevented the generation of relevant accident again.
As preferred version of the present invention, the angle that the position of described limited block 11 makes hydraulic cylinder 40 driving base plates 20 rotate around jointed shaft is 100 °～120 °.Above-mentioned angle is easy to realize and be convenient to control in practical operation.
As the further preferred version of the present invention, the angle that the position of described limited block 11 makes hydraulic cylinder 40 driving base plates 20 rotate around jointed shaft is 105 °～110 °.This angular range had both helped operation, and the upper surface that also helps base plate 20 can contact smoothly with the guide rail of bearing 50, thereby is preferable selection of the present invention.
