Description of the drawings
Fig. 1 is a kind of structural schematic diagram of lower die holder of the present invention；
Fig. 2 is A-A cutaway view Amplified images in Fig. 1.
Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
Figure is please referred to, the present invention provides a kind of technical solution：A kind of lower die holder, including workbench 1, workbench 1 are pacified
Loaded on press machine, the upper surface middle part of workbench 1 is provided with groove 11, and circumferential profile and the lower die of groove 11 are adapted, and
Lower part with lower die is in clearance fit, and the lower part of lower die more can be smoothly put into groove 11.
In order to which the lower die that will be located in groove 11 is fixed, 11 both sides of upper surface respective slot of workbench 1 have can
The left and right sliding block 2,3 of sliding, left and right sliding block 2,3 are driven by transmission mechanism 4 towards or away from movement.It is left and right when lower die is installed
Relatively far away from, transmission mechanism 4 drives left and right sliding block 2,3 to move towards to distance after lower die is lifted in groove 11 between sliding block 2,3
It is i.e. close to each other, when left and right sliding block 2,3 relative inner and lower die upper contact after, left and right sliding block 2,3 is by lower die top
It clamps.Similarly, when dismantling lower die, transmission mechanism 4 drives left and right sliding block 2,3 to be moved away from and is located remotely from each other, left and right sliding block 2,3
It disappears to the pressure on lower die top, then takes out lower die from workbench 1.
On the one hand the clamper of the present invention lower die can be clamped by left and right sliding block 2,3 firm, on the other hand left and right
Sliding block 2,3 can be automatically closer or far from lower die can be rapidly assembled and disassembled.
Transmission mechanism 4 can respectively drive two cylinders or ball-screw of left and right sliding block 2,3 etc..This implementation
Transmission mechanism 4 in mode includes left and right axis 41,42, transferring member 43, motor 44 and left and right inclined wedge 45,46, left and right axis 41,
42 are located at the opposite exterior lateral sides of left and right sliding block 2,3 and are vertically inserted into workbench 1, and motor 44 drives left axle rotation, transferring member
43 are located in workbench 1 and by the torque transfer of left axle to right axle 42, and left and right inclined wedge 45,46 is respectively sleeved in left and right axis 41,42
It is upper and with left and right axis 41,42 screw-thread fits, left and right inclined wedge 45,46 is respectively with left and right sliding block 2,3 in inclined wedge cooperation.
The operation principle of transmission mechanism 4 is：Motor 44 drives left axle 41 to rotate, and left axle 41 drives right axle by transferring member 43
42 rotate in same direction, and left and right inclined wedge 45,46 is symmetrical arranged, and left and right sliding block 2,3 is also symmetrical arranged, and the rotation of left and right axis 41,42 is logical
It crosses screw thread and is converted to moving up and down for left and right inclined wedge 45,46, moving up and down for left and right inclined wedge 45,46 is converted into left and right cunning
Block 2,3 opposite moves towards.As shown in the figure, left axle 41 and right axle 42 rotate counterclockwise, left and right inclined wedge 45,46 to
Lower movement, left and right sliding block 2,3 respectively to the left, the i.e. left and right sliding block 2,3 that moves right move towards, left and right sliding block 2,3 and lower die
Lower die is clamped after contact.
Transferring member 43 include left and right worm gear 431,432 and worm screw 433, left and right worm gear 431,432 be respectively sleeved in left axle and
In right axle, the both ends of worm screw 433 are engaged with left and right worm gear 431,432 respectively.Left worm gear 431 is rotated with left axle 41, left worm gear
431 driving worm screws 433 rotate, and worm screw 433 drives right worm gear 432 to rotate again, finally drives right axle 42 to rotate by right worm gear 432,
To realize the transmission of torque between left axle 41 and right axle 42.Transferring member 43 is located in workbench 1, that is to say, that workbench 1
It is interior that there is the space for accommodating transferring member 43.Transferring member 43 and the whole occupied space of transmission mechanism 4 and workbench 1 are smaller, structure
It is compact, stable drive.
It should be noted that transferring member 43 can also realize the torque transfer between left and right axis 41,42 by bevel gear,
A bevel gear is specifically respectively set on left and right axis 41,42, there are shaft, the both ends of shaft between left and right axis 41,42
Also there is the bevel gear engaged with the bevel gear on left and right axis 41,42, the torque of such left axle can pass to right axle.
Further include unloading mold mechanism 5 for the ease of taking out lower die out of groove 11, it includes on top plate 51 and pressure to unload mold mechanism
Mechanism 52, is provided with the channel for accommodating top plate 51 on the bottom surface of groove 11, Ya Shang mechanisms 52 be located at that workbench 1 is interior and its output end simultaneously
It is connect with top plate 51, top plate 51 is located at the middle part of groove 11, and when dismounting and change lower die, Ya Shang mechanisms 52 drive top plate 51 to moving up
It is dynamic, in the ejection out of groove 11 by lower die of upward outer force effect lower roof plate 51, so as to be convenient for changing lower die, similarly install
It so that top plate 51 is located at top when lower die and hold lower die to connect, the then decline of top plate 51 makes lower die drop down onto in groove 11, most
Lower die is clamped by left and right sliding block 2,3 again afterwards.It is lifted by top plate 51 to improve the efficiency of lower die installation and removal.
Ya Shang mechanisms 52 include left and right connecting rods 521,522 and left and right slide 523,524, as shown in Fig. 2, left and right connecting rods
521,522 is arranged in a crossed manner in longitudinal surface, and left and right slide 523,524 is capable of sliding back and forth to be connected to 51 lower surface of top plate, left,
The top of right connecting rod 521,522 is hinged with left and right slide 523,524 respectively, and left and right connecting rods 521,522 can be under its be respective
End is swung.It is mutually remote in left and right slide 523,524 longitudinal surfaces when the direction of left and right connecting rods 521,522 as shown in Figure 2 is swung
From top plate 51 declines；When left and right connecting rods 521,522 are by the opposite direction rotations of Fig. 2, left and right slide 523,524 is in longitudinal direction
Close to each other in face, top plate 51 rises.Left and right slide 523,524 is in the projection of horizontal plane on rectangular diagonal line, left,
Evenly, the lifting of top plate 51 is more steady for 523,524 pairs of 51 distribution of forces of top plate of right slide.
433 quantity of worm screw is two, and two worm screws 433 are located at the front and rear sides of left and right worm gear, left and right connecting rods
521,522 lower end is respectively sleeved on two worm screws 433 and is swung by two drivings of worm screw 433.Left and right connecting rods in Fig. 2
521,522 rotation direction is consistent with the rotation direction of Fig. 1 middle left and rights axis 41,42, that is to say, that when left and right axis 41,42 drives
When dynamic left and right sliding block 2,3 compresses lower die, top plate 51 moves down, opposite, when dismantling lower die, left and right axis 41,42 drives
Left and right sliding block 2,3 leaves each other to cancel the pressure to lower die, meanwhile, left and right connecting rods 521,522 will drive top plate 51 to rise
Lower die is ejected from groove 11.
Ya Shang mechanisms 52 drive top plate 51, Ya Shang mechanisms 52 and driver with the worm screw 433 in transmission mechanism 4 for power
Structure 4 is combined, and is interlocked with simplify control by mechanical structure, while mechanical interlocking improves operation stability.
