Abstract

Disclosed is a clamping mechanism device which can fast replace bed dies on a work station of a PU upper injection machine, a fixing hole is drilled on a base of the work station, a universal joint and a rotating screw which are mutually connected are sequentially mounted in the fixing hole, and the rotating screw is engaged and connected with a center shaft of a bed die. The clamping mechanism device relieves or fastens the bed die by enabling the center shaft to move up and down, and the center shaft is connected with the fixing hole on the work station via the universal joint. When the universal joint is rotated by a wrench, the universal joint drives a corresponding rotating shaft to rotate, because the rotating shaft has a section of conical surface, when the conical surface is screwed into the hole, the center shaft is forced to be lower, and at this moment the bed die is fastened. When the conical surface is screwed out of the hole, the center shaft is raised under the spring action, and at this moment the bed die is relieved, thereby the clamping mechanism device is high in die-changing efficiency and is not easy to damage dies.

Description

Clamping mechanism

Affiliated technical field

The utility model relates to a kind of device of helping to change fast on the injector station bed die that connects at PU.

Background technology

Connect at PU and to help that the existing mould mode that refoots is on the injector station, do an open slot on the bed die central shaft slope-shaped, when bed die is installed, locked mode screw under the bed die is suitably screwed out, be put into the opening part of bed die central shaft then, again bed die pushed away forward, because bed die central shaft open slot is the inclined slope structure, then bed die is more by fastening forward, and existing structure just reaches the purpose of locking bed die with this.But there is tangible drawback in it.At first be that efficient is low, when being installed, bed die to constantly try to screw out the length of bed die screw to reach the locking bed die, next locks bed die is that mould is before pushed away by force, therefore no matter be that screw or the groove on the bed die central shaft on the bed die is all fragile, improve the frequency of maintenance, had a strong impact on the output and the quality of shoemaking.

Summary of the invention

The utility model can solve the technical problem of present existence, and a kind of more scientific and efficient clamping apparatus is provided.

The technical scheme that the utility model adopted is: a kind of clamping mechanism, on the station base, be drilled with fixing hole, and interconnected universal joint, rotary screw are housed in the fixing hole successively and match with the bed die central shaft and be connected by rotary screw.

Unclamp or lock bed die by the mode that the bed die central shaft is moved up and down, no longer use the mode that bed die is pushed away to lock bed die forward, the bed die central shaft is connected with a fixing hole on the station with universal joint.When rotating universal joint with spanner, universal joint drives corresponding rotating shaft rotation, owing on the rotating shaft one section conical surface is arranged, when this conical surface precession hole, bed die central shaft limit is reduced by force, and this moment, bed die was fastening.When the conical surface screwed out the hole, the bed die central shaft rose under spring action, and this moment, mould unclamped.The beneficial effects of the utility model are, die change efficient height, and mould is not fragile.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Among the figure: 5. 4. 3. 2. 1. station base be universal joint, 6. rotary screw, 7. locked mode spring, 8. locating shaft, 9. central shaft.

The specific embodiment

With reference to accompanying drawing, the utility model clamping mechanism connects the station base help injector at PU and is drilled with fixing hole on 1., be equipped with successively in the fixing hole interconnected universal joint 2. 3. 4. 5., 9. 6. rotary screw match with the bed die central shaft 6. and by rotary screw and be connected.Wherein, 6. rotary screw has one section conical surface can enter or withdraw from taper hole on the central shaft, and 8. the rotary screw other end 6. is equipped with locating shaft; 7. 9. the bed die central shaft be equipped with the locked mode spring down.

When with the spanner fastening station base universal joint in 1. 2. 3. 4. 5. the time, the universal joint forward drives, and 6. rotary screw rotates, and when its conical surface screws in central shaft 9. the time, the bed die central shaft is spurred downwards by force, locks bed die at this moment.2. 3. 4. 5. backward rotation of universal joint when unclamping the universal joint of station base in 1. with spanner, its conical surface withdraws from the hole on the central shaft.Central shaft moves up under the spring force effect, unclamps mould this moment, and the utility model is by reaching fastening with upper type and purpose that unclamp bed die.

Claims

1. clamping mechanism is characterized in that: be drilled with fixing hole on the station base, interconnected universal joint, rotary screw be housed in the fixing hole successively and matched with the bed die central shaft by rotary screw and be connected.
