The mold provided by the utility model can be closely matched with locating holes in a steel sheet and is provided with a locating device.
Description
Technical field
The utility model relates to technical field of mold, particularly a kind of mould with pilot pin device.
Background technology
Along with industrial development, the requirement of product is more and more higher, ultra thin handset market demand is also increasing, but the thin glue position of some small sized product cannot moulding, that is to say and is difficult to thin away glue, therefore need steel disc in-mould injection, when in-mould injection steel disc, for preventing walking and being out of shape of steel disc in injection moulding process, steel disc must offer two above locating holes for locating, and for what locate steel disc, is pilot pin device in mould.
Pilot pin device of the prior art, as shown in Figure 1, pilot pin device comprises location shank and the shank countersunk head that is arranged at shank one end, location, and location shank is columned location shank, pilot pin device is arranged at the die with shaping mold cavity, and has limiting plate to be defined in die.
Pilot pin device of the prior art is because location shank is cylindric, in actual use, because there is certain margin of tolerance in locating hole diameter on steel disc, cause locating shank and locating hole in assembling process, easily occur below two problems: the one, when the diameter of locating hole is less than normal, locate shank and locating hole and have interference fit, can cause steel disc cannot be assembled on mould or force that steel disc is assembled to mould and cause steel disc distortion; The 2nd, when the diameter of locating hole is bigger than normal, can there is gap in coordinating between location shank and locating hole, make steel disc there will be movement.
Utility model content
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of can with steel disc on the close-fitting mould with positioner of locating hole.
The purpose of this utility model is achieved through the following technical solutions:
A kind of mould with pilot pin device is provided, comprise die, limiting plate and pilot pin device, described pilot pin device comprises pilot pin, described pilot pin comprises location shank and is arranged at the shank countersunk head of shank one end, described location, described pilot pin device also comprises self adaptation elastic component, described self adaptation elastic component one end and described shank countersunk head butt, the other end butt of described self adaptation elastic component and described limiting plate, described location shank comprises straight-bar portion and cone bar portion, described cone bar portion is cone structure setting, the end face that described straight-bar portion and described cone bar portion join is for intersecting end face, described crossing end face is positioned at described die.
Wherein, described crossing end face is arranged in described die.
Wherein, described cone bar portion is spherical end surface setting towards outer end.
Wherein, described self adaptation elastic component is spring.
Wherein, described shank countersunk head and the one-body molded setting of described location shank.
The beneficial effects of the utility model:
In use, steel disc is assembled on mould, when on steel disc, the diameter of locating hole is less than normal, the cone bar portion of steel disc and described pilot pin produces and interferes, steel disc will produce a downward active force for whole pilot pin device, because the self adaptation elastic component at described pilot pin top has contractile properties, described pilot pin will move downward, thereby the steel disc distortion of avoiding described location shank and described locating hole interference fit to cause, and when on steel disc, the diameter of locating hole is bigger than normal, the self adaptation elastic component of described pilot pin bottom will produce an active force making progress, the cone bar portion of described location shank is matched with the locating hole of steel disc, so that coordinating between described location shank and described locating hole can be not gapped.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is the structural representation of existing pilot pin device.
Fig. 2 is a kind of structural representation with the mould of pilot pin device of the utility model.
In Fig. 2, include:
1-die, 2-limiting plate, 31-location shank, 311-straight-bar portion, 312-cone bar portion, 32-self adaptation elastic component, 33-shank countersunk head, 34-intersect end face, 4-steel disc.
The specific embodiment
With the following Examples the utility model is further described.
A kind of specific embodiment with the mould of pilot pin device of the present utility model, as shown in Figure 2, comprise die 1, limiting plate 2 and pilot pin device, described pilot pin device comprises pilot pin and is the self adaptation elastic component 32 of spring, described pilot pin comprise location shank 31 and with the shank countersunk head 33 of described location shank 31 one, described self adaptation elastic component 32 one end and described shank countersunk head butt, the other end butt of described self adaptation elastic component 32 and described limiting plate 2, described shank countersunk head 33 is arranged at described location shank 31 between described die 1 and described limiting plate 2 and comprises straight-bar portion 311 and cone bar portion 312, described cone bar portion 312 is cone structure setting, the end face that described straight-bar portion 311 and described cone bar portion 312 join is for intersecting end face 34, described crossing end face 34 is positioned at described die 1.
In use, steel disc 4 is assembled on mould, when on steel disc 4, the diameter of locating hole is less than normal, steel disc 4 produces interference with the cone bar portion 312 of described pilot pin, steel disc 4 will produce a downward active force for whole pilot pin device, because the self adaptation elastic component 32 at described pilot pin top has contractile properties, described pilot pin will move downward, thereby steel disc 4 distortion of avoiding described location shank 31 and described locating hole interference fit to cause, and when on steel disc 4, the diameter of locating hole is bigger than normal, the self adaptation elastic component 32 of described pilot pin bottom will produce an active force making progress, the cone bar portion 312 of described location shank 31 is matched with the locating hole of steel disc 4, so that coordinating between described location shank 31 and described locating hole can be not gapped.
Further, described cone bar portion 312 is spherical end surface setting towards outer end.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
