Description
Technical field
The utility model relates to compression tool, relates in particular to a kind of core-pulling slide block locking mechanism.
Background technology
When the plastic products sidewall with the through hole groove, during boss, plastic products can not directly be deviate from mould, must be with forming hole, the forming part of groove and boss is made movable, is called moving core.The mechanism that finishes the active type extraction and reset is called core-pulling mechanism.
Because goods side shaping area is larger, the moulding of need loosing core on four sides of compression tool structure, compression tool was loosed core on four sides and usually can't be locked under the effect of forming materials pressure between each wallboard this moment.
The utility model content
The technical problem that the utility model solves is: solve the problem that compression tool is loosed core and can't be locked under the effect of forming materials pressure between each wallboard on four sides.
For reaching this purpose, the utility model by the following technical solutions:
A kind of core-pulling slide block locking mechanism comprises patrix, middle cover and counterdie, is provided with the pull bar guide pillar on the described patrix, is provided with stopper slot on the described pull bar guide pillar;
Described middle cover is connected with the pull bar guide pillar, described middle cover both sides level be provided with groove, be provided with arm-tie in the groove, the corresponding stopper slot of described arm-tie is provided with breach, the both sides arm-tie connects by pull bar, puts in described and is provided with curved pin;
Be provided with guide rail on the described counterdie, be provided with slide block in the described guide rail, be provided with the through hole corresponding with described curved pin on the described slide block, described curved pin from middle cover junction to its end gradually to middle cover outer bend;
Described slide block vertical plane is the inclined-plane, puts the be provided with wedge corresponding with described inclined-plane in described.
Further, described patrix, middle cover and counterdie are rectangular configuration, and described pull bar guide pillar is four and is separately positioned on four jiaos of patrixes, and described curved pin is arranged on middle cover four limits, and guide rail and slide block on the counterdie corresponding with described curved pin are four.
Further, put in described and also be provided with limited block, corresponding with the described limited block spacing preiection that is provided with on the described arm-tie.
Further, described wedge puts in being fixed by screws in.
Further, be provided with lead on the described counterdie.
The beneficial effects of the utility model are: it is corresponding with slide block to be provided with wedge in the middle cover, make middle cover stay counterdie during die sinking, cover wedge locking four sides slide block has solved the problem that compression tool is loosed core and can't be locked between each wallboard on four sides in the utilization under the effect of forming materials pressure.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Shown in Fig. 1～4, in present embodiment, a kind of core-pulling slide block locking mechanism described in the utility model comprises patrix, middle cover 6 and counterdie, is provided with pull bar guide pillar 7 on the described patrix, is provided with stopper slot on the described pull bar guide pillar 7.
Described middle cover 6 is connected with pull bar guide pillar 7, described middle cover 6 both sides levels be provided with groove, be provided with arm-tie 5 in the groove, described arm-tie 5 corresponding stopper slots are provided with breach, the both sides arm-tie connects by pull bar 8, is provided with curved pin 3 on the described middle cover 6; Also be provided with limited block 4 on the described middle cover 6, corresponding with described limited block 4 spacing preiection that is provided with on the described arm-tie 5.
Be provided with guide rail 1 on the described counterdie, be provided with slide block 9 in the described guide rail 1, be provided with the through hole corresponding with described curved pin 3 on the described slide block 9, described curved pin 3 from middle cover 6 junctions to its end gradually to middle cover 6 outer bend.Described slide block 9 vertical planes are the inclined-plane, corresponding with the described inclined-plane wedge 10 that is provided with on the described middle cover 6, and described wedge 10 is fixed on the middle cover 6 by screw 11.
Described patrix, middle cover 6 and counterdie are rectangular configuration, described pull bar guide pillar 7 is four and is separately positioned on four jiaos of patrixes, described curved pin 3 is arranged on middle cover 6 four limits, and the guide rail 1 on the counterdie corresponding with described curved pin 3 is four with slide block 9, is provided with lead on the described counterdie.
During die sinking, mould pull bar guide pillar 7 moves up with the folding modular system of hydraulic press, when patrix and reinforced chamber break away from a segment distance, cover 6 moved upward during stopper slot active force on the pull bar guide pillar 7 drove on arm-tie 5, the curved pin 3 that be fixed on the middle cover 6 this moment acts on the core-pulling slide block 9, and the 9 generation translations of band movable slider are finished and loosed core.This moment, goods were stayed in the counterdie, ejected goods by push rod under the effect of press liftout tank.With waste material in the compressed air blowing-out mold cavity, the curved pin 3 band movable sliders 9 that are fixed on during matched moulds on the middle cover 6 make it to reset.Manually pull open pull bar 8 and drive arm-tie 5 to certain position, then die sinking makes middle cover 6 stay counterdie, cover 6 wedges 10 locking four sides slide blocks 9 in the utilization.Blowing, the mould matched moulds, the pressurize moulding, pushing drawing rod 8 makes it to reset
The wedge 10 that is fixed on the cover 6 is adjacent to the action of just having finished middle cover 6 locked modes with wallboard 2 inclined-planes.
Arm-tie 5 is pulled out, and pull bar guide pillar 7 does not hook arm-tie 5, and middle cover 6 stays in counterdie, and patrix is partly thrown off, and is reinforced again, the next goods of moulding
Arm-tie 5 advances, and pull bar guide pillar 7 hooks arm-tie 5, because arm-tie 5 is fixed on the middle cover 6, so pull bar guide pillar 7 opens middle cover 6, wedge 10 is loosening, and loosing core just begins to slide.
What need statement is; the above-mentioned specific embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with expected easily or replacement all should be encompassed in the protection domain of the present utility model.
