Description
Technical field
Injection mold technology is the utility model is related to, more specifically, it relates to which a kind of injection mold is automatic multiple
Position thimble structure.
Background technology
Thimble is to be used for molding product in ejection die, and traditional die ejector pin is the equal cylinder top of an outside diameter
Bar, cylindrical, top shank are equipped with cylindrical thimble countersunk head, and the die ejector pin of this structure is installed in mounting hole in a mold, when
When needing to eject moulded products, the thimble rod of die ejector pin is stretched out out of mounting hole, and product is ejected.
As described in Figure 3, it includes template 1, mode 2, ejector retainner plate 3 and thimble 4, thimble 4 to thimble structure of the prior art
Moved back and forth on ejector retainner plate 3 with ejector retainner plate 3, thimble 4 passes through template 1 and mode 2, at the surface of mode 2, is used for
Finished product is jacked up.
But when ejecting larger product, since thimble length is long, diameter is small, in ejection, thimble has stress appearance
It is yielding, it is easily broken；In addition, when ejecting large-scale product at the same time using multiple thimbles, ejecting and retracting during, thimble
Impact direction is different, is also easy to produce force unbalance and makes the stuck phenomenon of thimble.
Utility model content
A kind of in view of the deficienciess of the prior art, automatically reseting the purpose of this utility model is to provide injection mold
Thimble structure, it, which has, makes thimble be unlikely to deform, be broken, and prevents stuck advantage with automatically reseting.
To achieve the above object, the utility model provides following technical solution：
A kind of thimble structure that automatically resets of injection mold, including template, mode, ejector retainner plate and thimble, the template and
Mode is provided with the mounting hole passed through for thimble, and the thimble is split as thimble and lower thimble, and the mounting hole is located at upper top
Inner wall at pin is coaxially arranged with relief hole, and the outer circle wall that the upper thimble is located in relief hole is provided with can be with relief hole
The locating piece that bottom surface offsets, the spring passed through for upper thimble is provided with the relief hole, and the spring is located at the top of relief hole
Between face and locating piece.
Preferably, the diameter of the lower thimble is more than the diameter of the upper thimble.
Preferably, the length of the lower thimble is 1.5-2 times of the upper thimble length.
Preferably, the locating piece is the self-locking nut being connected by screw thread with upper thimble.
Preferably, the top of the upper thimble is coaxially arranged with the pushing block flushed with the surface of mode, in the mounting hole
It is coaxially arranged with the limit hole consistent with limited block profile.
In conclusion the utility model has the advantages that：
In ejecting product, lower thimble applies thrust under the driving of ejector retainner plate to upper thimble, meanwhile, determine on upper thimble
Position block is compressed spring accumulation elastic potential energy, retracts product is released back center plate, lower thimble resets, and upper thimble is in bullet
Automatically reset under the elastic force of spring, upper thimble is retracted when retracting for individual, from the influence of unitary mould degree of deformation, effectively prevents card
Extremely；The length of lower thimble is more than upper thimble length, and diameter is also bigger than upper thimble, and lower thimble can bear the power of bigger and constant
Shape, the thimble of two-part can effectively prevent because thimble is elongated and deformed damaged；By setting pushing block on the top of upper thimble, upper
Thimble can position upper thimble when resetting, and make pushing block surface keep flushing with mode surface.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
The present embodiment is only explanation to the utility model, it is not the limitation to the utility model, this area skill
Art personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but as long as
All protected in the right of the utility model be subject to Patent Law.
A kind of 4 structure of thimble that automatically resets of injection mold, with reference to Fig. 1 and 2, it includes template 1, mode 2, ejector retainner plate 3
With thimble 4, template 1 and mode 2 are provided with the mounting hole 5 passed through for thimble 4, and thimble 4 is split as thimble 41 and lower thimble 42；
The diameter of lower thimble 42 is more than the diameter of upper thimble 41, and the length of lower thimble 42 is 1.5-2 times of upper 41 length of thimble, under
Thimble 42 is relatively thick, and not pliable deformation, upper thimble 41 plays thimble 42 shorter relatively, is also not susceptible to bend.
The inner wall that mounting hole 5 is located at upper thimble 41 is coaxially arranged with relief hole 51, and 51 diameter of relief hole is more than mounting hole
5, relief hole 51 is divided to two upper and lower holes for docking, is separately positioned on mode 2 and template 1, in order to process；Upper thimble 41
Be provided with through the outer circle wall that in relief hole 51 to template 1, upper thimble 41 is located in relief hole 51 can be with relief hole for bottom
The locating piece 411 that 51 bottom surface offsets, locating piece 411 are the self-locking nut of position-adjustable.
The top of upper thimble 41 is coaxially arranged with the pushing block 412 flushed with the surface of mode 2, is coaxially disposed in mounting hole 5
There is the limit hole 52 consistent with limited block profile, when upper thimble 41 resets, pushing block 412 is right automatically into in limit hole 52
Upper thimble 41 is positioned, and the top surface of pushing block 412 is flushed with the surface of mode 2.
Operation principle is as follows：In ejecting product, lower thimble 42, which applies upper thimble 41 under the driving of ejector retainner plate 3, to be pushed away
Power, meanwhile, the locating piece 411 on upper thimble 41 is compressed accumulation elastic potential energy to spring 511, and product is being released back center
Plate 3 retracts, and lower thimble 42 starts to reset, and upper thimble 41 retracts under the elastic force of spring 511, until pushing block 412 enter to it is spacing
In hole 52, upper thimble 41 automatically resets completion；By the tightness for rotating self-locking nut adjustable springs 511.
