Description
Technical field
This utility model relates to mould manufacture field, specifically a kind of Novel mandril.
Background technology
In plastics mould and compression mod, push rod is mainly used to from punch or die to depart from the product of injection mo(u)lding punch or die.When injection or during die casting, some product is on punch or stays in die, is at this moment accomplished by push rod and is ejected by product, make product disengaging punch or die.In cold-punching mould, the product of the product swept away or the product of press-bending or stretching to be ejected from die by push rod or die pad.In these cases, without push rod, product is difficult to take out.
Existing push rod entirety suitability is poor, it is difficult to realize the unified use of multiple mould, hence in so that overall one-tenth raises, uses the most inconvenient simultaneously, and it main reason is that the jacket structure complexity that the body of rod is supporting, and cost is high.
Utility model content
The purpose of this utility model is to provide a kind of Novel mandril, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of Novel mandril, including push rod body and oversheath, push rod body is made up of the body of rod and head, and head is fixed on the head-end location of the body of rod；Described oversheath is made up of locating sleeve, phase magnet and adpting flange, the center of adpting flange offers a jack, the inwall of jack is provided with female thread structure, and the head end of locating sleeve is provided with union joint, and the centre bore of union joint is connected with the tube chamber of locating sleeve；The outer wall of described union joint is provided with the external thread structure matched with jack female thread, and therefore locating sleeve can quickly be connected with adpting flange；Phase magnet is fixed on the tail end of locating sleeve, and the center of phase magnet is provided with the through hole being connected with locating sleeve tube chamber, therefore during actually used, by selecting the locating sleeve of certain specification to be connected with adpting flange, now phase magnet is adsorbed at mold releasability hole, now the body of rod is sequentially passed through jack, union joint, locating sleeve and through hole, in the body of rod inserts demoulding hole the most at last, now under the effect of locating sleeve, the body of rod can effectively be protected, locating sleeve can realize quickly changing simultaneously, so make use cost lower.
As further program of the utility model: described phase magnet is provided with draw-in groove, draw-in groove is utilized to facilitate locating sleeve to be connected with phase magnet, now being only that caliber is different due to the specification of locating sleeve, the various combination that therefore can realize single phase magnet uses.
As this utility model further scheme: described locating sleeve uses stainless steel to make, locating sleeve is utilized to prevent the body of rod from the situation of bending occurring during squeezing into demoulding hole.
As this utility model further scheme: the described body of rod and head use integral structure.
Compared with prior art; the beneficial effects of the utility model are: this utility model is rational in infrastructure; easy to use, under the effect of locating sleeve, the body of rod can effectively be protected; locating sleeve can realize quickly changing simultaneously; so making use cost lower, phase magnet is provided with draw-in groove, utilizes draw-in groove to facilitate locating sleeve to be connected with phase magnet; now being only that caliber is different due to the specification of locating sleeve, the various combination that therefore can realize single phase magnet uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel mandril of this utility model.
In figure: the 1-body of rod, 2-head, 3-oversheath, 4-locating sleeve, 5-phase magnet, 6-jack, 7-adpting flange, 8-through hole, 9-union joint.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of Novel mandril, including push rod body and oversheath 3, push rod body is made up of the body of rod 1 and head 2, and head 2 is fixed on the head-end location of the body of rod 1；Described oversheath 3 is made up of locating sleeve 4, phase magnet 5 and adpting flange 7, the center of adpting flange 7 offers a jack 8, the inwall of jack 8 is provided with female thread structure, and the head end of locating sleeve 4 is provided with union joint 9, and the centre bore of union joint 9 is connected with the tube chamber of locating sleeve 4；The outer wall of described union joint 9 is provided with the external thread structure matched with jack 8 female thread, and therefore locating sleeve 4 can quickly be connected with adpting flange 7；Phase magnet 5 is fixed on the tail end of locating sleeve 4, and the center of phase magnet 5 is provided with the through hole 6 being connected with locating sleeve 4 tube chamber, therefore during actually used, by selecting the locating sleeve 4 of certain specification to be connected with adpting flange 7, now phase magnet 5 is adsorbed at mold releasability hole, now the body of rod 1 is sequentially passed through jack 8, union joint 9, locating sleeve 4 and through hole 6, in the body of rod 1 inserts demoulding hole the most at last, now under the effect of locating sleeve 4, the body of rod 1 can effectively be protected, locating sleeve 4 can realize quickly changing simultaneously, so make use cost lower.
