Motion bar is enabled to push ejector retainner plate return with lever principle and friction process；
Third, technical solution provided by the utility model are to be improved based on existing mold, therefore this is practical new
Applied widely, the strong flexibility of type.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the schematic device of the utility model embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, described embodiment is only the utility model section Example, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute under that premise of not paying creative labor
The every other embodiment obtained, fall within the protection scope of the utility model.
Upper top surface, side etc. involved in the present embodiment are named on the basis of thimble moving direction, and are being illustrated
It is illustrated under orientation description in book attached drawing.
As shown in Figure 1, impaired in order to solve to be used for a long time rear spring in traditional moulds, thimble and ejector retainner plate are difficult to return
Completely, the problem for being easy to cause mold pressing mold and mold to be damaged, the present embodiment propose a kind of mould ejector pin returning device,
It mainly includes motion bar 10；One end end of motion bar 10 is contacted with the side of ejector retainner plate, and other end end is installed on mold
Upper top surface；Play spring consistent with spring, therefore connecting ejector retainner plate by the setting of motion bar 10 in this present embodiment
And motion bar 10 is located at the same side of ejector retainner plate, guarantees that motion bar 10 while spring sufficiently cannot reset ejector retainner plate, enables
Thimble sheet reset is complete；In the present embodiment, motion bar 10 can be made with 10 length of motion bar to be half using its fixing end endpoint as the center of circle
The circular motion of diameter, while in order to guarantee motion bar 10 to the impetus of ejector retainner plate, ejector retainner plate is coped in the end of motion bar 10
Side implement pressure, enable the spring that connect with ejector retainner plate keep the state that do not stress.
Supplementing structure of the motion bar 10 as spring is used in the present embodiment, since mold is during jack-up, by inside
Mechanical Driven, therefore the setting of motion bar 10 will not influence its jack-up process, and in reseting procedure, traditional ejector retainner plate is only
It is driven by spring, the course of work of mold itself now is nor affected on to the thrust of ejector retainner plate plus motion bar 10, and guarantee thimble
Sheet reset is complete, to guarantee mold integrality, reduces a possibility that mold is impaired.
It more specifically, further include the fixed block 20 for being fixedly installed on top surface on ejector retainner plate；One end end of motion bar 10 is straight
It connecing and is resisted against on fixed block 20, therefore during jack-up, fixed block 20 pushes one end of motion bar 10 to circle, due to
Motion bar 10 has the movement tendency for pushing fixed block 20, and in reseting procedure, motion bar 10 pushes fixed block 20 mobile, pushes up simultaneously
Needle plate replys original state, thimble return.
More specifically, the upper top surface of mold is additionally provided with stopper 30, the length direction and setting direction of stopper 30
Consistent with the moving direction of thimble, the shortest distance is equal to the length of motion bar 10 between 10 fixing end of stopper 30 and motion bar,
Therefore under ejection state and reset state, the mantle friction of motion bar 10 and stopper 30, under rubbing action and thick stick
Under the action of rod principle, motion bar 10 generates thrust to fixed block 20, and fixed block 20 is enabled to restore, i.e., ejector retainner plate is replied former
Shape.
The motion bar 10 that is set as of stopper 30 is further defined the thrust of fixed block 20, and motion bar 10 is in movement
In the process, due to rubbing between stopper 30, there can be opposition, since 10 one end end of motion bar is fixed, motion bar
10 have active force for fixed block 20, therefore can generate impetus to fixed block 20, so as to realize answering for ejector retainner plate
Position effect.
More specifically, top surface is additionally provided with locating piece 40 on mold；The one side of locating piece 40 is close to stopper 30, simultaneously
Locating piece 40 and motion bar 10 are divided into the symmetrical two sides of stopper 30.Since 30 one end of stopper is set to top surface on mold,
The other end provides frictional force under the premise of not influencing mold work, for motion bar 10, therefore does not fix, and locating piece 40 is deposited
Enabling stopper 30 not change position under the action of 10 frictional force of motion bar, guarantee 30 position of stopper in the present embodiment
It is fixed, therefore guarantee that motion bar 10 for the impetus of fixed block 20, is further ensured that in the present embodiment that ejector retainner plate can answer
Position is completely.
In conclusion in the present embodiment using motion bar, that stopper realizes motion bar is complete for thimble sheet reset
Structure enables the mold using returning device provided in this embodiment, and during being used for a long time, it is multiple ejector retainner plate will not occur
The incomplete phenomenon in position, guarantees the service life of mold and the integrality of structure.
Embodiments described above does not constitute the restriction to the technical solution protection scope.It is any in above-mentioned implementation
Made modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution within the spirit and principle of mode
Within enclosing.
