1102, movable stand 2 1102 is provided with the hook 2 1106 for being easy to draw mould bases 9, and the inner side of limit base 1101 is placed with some and mould
The lateral wall of frame 9 is oriented to the directive wheel 1108 coordinated, and limit base 1101 is arranged on the outside base 1105 of mould bases guide rail 2 1104,
The upside of mould bases guide rail 2 1104 is flushed with the upside of mould bases guide rail 1.
In order to further improve the reliability of the motion of mold-change trolley 5, one end of track 4 away from press bench 1 is provided with
The limiting plate 12 that limitation mold-change trolley 5 is continued to move to, when roller 513 is contradicted on limiting plate 12, mould bases 9 is just in crane
806 underface.
It should be noted that linear actuator 702 is preferably single-rod cylinder in the present embodiment；Arranged in the present embodiment
There are 3 press bench 1.
During present invention work, transmitting device 7 is transported to the press bench 1 for needing to change mould bases 9 as needed,
By taking the mould bases 9 for changing left side press bench 1 as an example, it is specifically, the piston rod of linear actuator 702 is constantly retracted, directly
Line drive 702 drives vertical support base 701 to be moved to the left, and vertical support base 701 drives plate conveyor 714 to move horizontally to the left,
When plate conveyor 714 is moved horizontally to before left side press bench 1, lifting hydraulic cylinder 718 is acted, on lifting hydraulic cylinder 718
Rise or decline, plate conveyor 714 is placed in the lower section of mould bases 9, mould bases 9 is removed to plate conveyor 714, gas circuit produces vacuum cup 709
Raw vacuum adsorbs mould bases 9 in plate conveyor 714, and the expansion link of control linear actuator 702 constantly stretches out, vertical support base
701 be moved horizontally to horizontal support seat 708 one end when, the stopping of linear actuator 702 action, reductor 1 act, reductor
One 504 rotations with movable sprocket 1, sprocket wheel 1 passes through rotation of the chain 1 with movable sprocket 2 510, sprocket wheel 2 510
The rotation of roller shaft 519 is driven, the roller 513 of mold-change trolley 5 is moved along track 4 to the place direction of plate conveyor 714, now rolled over
Curved joint arm 710, joint arm 710 drives upper axle 722 and lower axle 721 to rotate, and joint arm 710, which is folded, to be rotated, the bending of joint arm 710
To plate conveyor 714 in the surface of mold-change trolley 5, mould bases 9 is transported on mould bases guide rail 1, mould bases 9 is placed in mold-change trolley
On 5, the piston rod of lifting fluid cylinder 514, which stretches out, makes lifting platform 508 concordant with mould bases guide rail 1, makes more putting down for the placement of mould bases 9
Surely, when mold-change trolley 5 is contradicted on baffle plate 505, lift cylinder 520, which rises limited post 521, fixes mould bases 9, prevents mold changing
Dolly 5 move when mould bases 9 vibration, the counteragent of reductor 1, make mold-change trolley 5 move backward to crane 806 just under
Motor 1107 on side, a mold frame library 11 is acted, and drives chain 3 1103 to promote movable stand to be moved to mold-change trolley 5, hook
2 1106 hook mould bases 9, the counteragent of motor 1107, and movable stand 2 1102 hauls mould bases 9 to mould bases guide rail 2 1104, another
Motor 1107 on individual mold frame library 11 is acted, movable stand 2 1102 promote new mould bases 9 to mold-change trolley 5 direction move,
New mould bases 9 is placed on mold-change trolley 5, reductor 1 is acted, makes mold-change trolley 5 be moved to immediately below plate conveyor 714 to be
Only, new mould bases 9 is placed into plate conveyor 714, linear actuator 702 drives vertical support base 701 to be moved to the left, and works as transport
When plate 714 is moved horizontally to before left side press bench 1, new mould bases 9 is changed in forcing press, forcing press can be immediately
Carry out the work；While mould bases 9 are changed, lifting hydraulic cylinder 801 acts and drives crane 806 to decline, and crane 806 is close to
When in top mold frame, crane 806 and top mold frame are tightened together, the counteragent of lifting hydraulic cylinder 801 drives crane
806 are moved up, and the stopping of lifting hydraulic cylinder 801 is acted when above moving on to correct position, and crane 806 is static；Another transmitting device 7 is moved
Make, new core rod is placed in plate conveyor 714, bending joint arm 710 makes plate conveyor 714 be placed in immediately below top mold frame, lifts liquid
The elevating lever of cylinder pressure 718 constantly stretches out, and lifting hydraulic cylinder 718 drives vertical sliding seat 715 to be slid up along upright guide rail 705
It is dynamic, new core rod is changed onto top mold frame, on the outside of the bending of joint arm 710 to lift, lifting hydraulic cylinder 801, which drives, to be risen
Drop frame 806 is moved down, until top mold frame and lower mold holder coordinate again, so as to complete mold changing, the mould bases 9 after replacing treats next forcing press
Use；The present invention can complete the biography of mould bases 9 in different pressures machine worktable 1 according to actual needs by the setting of transmitting device 7
Defeated, mold-change trolley 5 can automatically move transport mould bases 9, and automaticity is high, improve mold changing efficiency, and the setting of mold frame library 11 is realized
The replacing of new mould bases 9, transports new mould bases 9 to forcing press while core rod is changed, and further improves mold changing efficiency；This hair
It is bright to can be applied in more the changing jobs of mould bases 9 in forcing press.
The invention is not limited in above-described embodiment, on the basis of technical scheme disclosed by the invention, the skill of this area
Art personnel are according to disclosed technology contents, it is not necessary to which performing creative labour just can make one to some of which technical characteristic
A little to replace and deform, these are replaced and deformation all falls in the scope of protection of the present invention.
