In groove bottom, surface that exposed surface and the die mandrel on the inside of the die ontology are exposed on the inside of the die ontology
Collectively form the mold cavity surface of the die ontology.
One side of the boss portion of the die mandrel away from the threaded portion is concordant with the groove bottom of the big groove.
The shape of cross section of the big groove is circular, ellipse or parallelogram.
The boss portion is cylindrical structure, and the boss portion and threaded portion are coaxial, the cylinder of the boss portion and institute
The sidewall surfaces for stating little groove are engaged.
The beneficial effects of the utility model are：
Die mandrel of the present utility model can be mounted directly on mould from the medial surface of mould, therefore be passed through without setting
The plug mounting hole inside and outside mould is worn, makes mould structure simpler, and effectively saves die space, when designing cooling water channel also
Without considering to avoid plug mounting hole, therefore cooling water channel can be arranged on to the position close proximity to die cavity as the crow flies, both obtained
Get Geng Gao cooling effectiveness, the processing of cooling water channel is greatly simplify again, reduce die cost.
Brief description of the drawings
Fig. 1 is the structural representation of existing die mandrel；
Fig. 2 is the structural representation of die mandrel of the present utility model；
Fig. 3 is the perspective view of one embodiment of die mandrel of the present utility model；
Fig. 4 is the structural representation of one embodiment of injection mold of the present utility model.
Embodiment
As shown in Figure 2,3, the utility model discloses a kind of novel die plug 3, it passes through and set successively
There are tapered cores 3-1, prism portion 3-2, boss portion 3-3 and threaded portion 3-4, the tapered cores, prism portion and threaded portion are kept
Coaxially, the radial direction full-size of the boss portion is more than the radial direction full-size in other each portions, and the tapered cores are that inner end is big
The small frustum cone structure in outer end, the radial direction full-size in the prism portion are more than the maximum diameter of the tapered cores.The spiral shell
Line portion is used for fixation of the die mandrel on mould, and the boss portion is used for the axial direction when die mandrel is installed and determined
Position, the prism portion is clamped using instrument during installation, the die mandrel is screwed on mould.The tapered cores are used for spiral shell
The shaping of endoporus is reserved in post.When institute's injecting products will interfix with other structures part, then reserve endoporus to this and twist
Enter tapping screw.Die mandrel of the present utility model can be mounted directly on mould from the medial surface of mould, therefore need not set
The plug mounting hole inside and outside the mould is put, also just without considering to avoid plug mounting hole when designing cooling water channel, therefore can be with
Cooling water channel is arranged on to the position close proximity to die cavity as the crow flies, had both obtained higher cooling effectiveness, greatly simplify again cold
But the processing in water route.
The prism portion is preferably positive six prismsby structure, is installed to the die mandrel using outer hexagonal spanner with facilitating
On mould.The diameter of the inscribed cylinder of the positive six prismsby should be greater than the maximum diameter of the tapered cores.
In the plane that the prism portion connects with the boss portion, the edge in the prism portion should be without departing from the boss portion
Edge, center of the prism portion preferably adjacent to the boss portion.
For the higher injecting products of the position accuracy demand of the reserved endoporus of screw pole, the boss portion is preferably cylinder
Body structure, and the boss portion is preferably coaxial with threaded portion, by the use of the boss portion as the die mandrel install when radial direction
Positioning.
The axial dimension in the prism portion is preferably the 1/6-1/4 of the axial dimension of the tapered cores.Both instrument is ensured
The prism portion can effectively be clamped, be unlikely to occupy positioned at the positive six prismsby shape hole of reserved endoporus oral area after making shaping again
The excessive axial length of reserved endoporus.
The invention also discloses a kind of injection mold, as shown in figure 4, including die ontology 4 and die mandrel, it is described
Die mandrel uses any one above-mentioned described novel die plug 3, the medial surface of the die ontology be provided with one or
Every many places plug mounting hole, the plug mounting hole includes the big groove 4-1 of all round closure, in the groove bottom of the big groove
The little groove of all round closure is offered, the groove bottom of the little groove is provided with tapped blind hole 4-2, each plug mounting hole
One die mandrel of middle installation, the medial surface of the die mandrel from the die ontology are installed to the die ontology
On.Under installment state, the threaded portion of the die mandrel is screwed in the tapped blind hole, the boss portion court of the die mandrel
It is fitted in the one side of threaded portion in the groove bottom of the little groove, exposed surface and the mould on the inside of the die ontology
The surface that tool plug is exposed on the inside of the die ontology collectively forms the mold cavity surface of the die ontology.The tapered core
Portion, prism portion, the surface of the surface of boss portion and the big groove are provided commonly for forming screw post, wherein the tapered cores,
The endoporus of screw pole described in the surface forming in prism portion, the surface of the big groove are mainly used in the outer surface of forming screw post.
The oral area that screw pole after shaping reserves endoporus is positive six prismsby shape hole, can play guiding to a certain extent to tapping screw and make
With at least its side wall can not interfere with tapping screw.Using above-mentioned die mandrel and its installation on die ontology
Structure, in die ontology cooling water channel 4-3 arrangement greatly simplified.Cooling water channel can be arranged on mould sheet as the crow flies
In body, without being arranged to crisscross to avoid plug mounting hole, therefore cooling effectiveness can significantly improve, but also
Substantial amounts of perforate operation is substantially eliminated, makes processing and assembling all simpler, therefore also reduce die cost.
The boss portion of the die mandrel deviates from groove bottom of the one side of the threaded portion preferably with the big groove and put down
Together, screw pole top anchor ring keeps effective width after enabling shaping, because top surface is typically injection-moulded plastic part and other structures part phase
Positioning reference plane during to fixing, effective width is kept to may insure effectively to position.
The shape of cross section of the big groove can be circular, ellipse or parallelogram, or other it is existing it is various can
The shape of energy.The shape determines the profile of the cross section of screw pole.
In the case of the boss portion is cylindrical structure and the boss portion coaxial with threaded portion, the boss portion
Cylinder is engaged with the sidewall surfaces of the little groove, for die mandrel in radial positioning.
