Correspondence position is provided with pilot hole, and when core rod is positioned at guide groove bottommost, core rod termination is inserted in pilot hole, and during the demoulding, core rod is from leading
Groove bottommost is deviate from toward top, and when ramp effect, core rod the most from inside outwards moves, and makes core rod termination depart from the product in pilot hole
Product, complete the demoulding.
The mould structure of described a kind of core pulling, it is characterised in that described press plates upper surface has at least two
One groove, die cavity lower surface correspondence position is provided with the second groove of same number, the first corresponding groove and the second groove and is formed
Space in be provided with spring, when press plates upper surface and die cavity lower surface are of completely closed, spring is compressive state.
The mould structure of described a kind of core pulling, it is characterised in that described core rod termination is provided with I-groove, passes through
I-groove is movably arranged in guide groove.
The mould structure of above-mentioned a kind of core pulling, including die cavity and the press plates that is connected with its clearance fit, press
Plate is symmetrically arranged on two with I-shaped guide pad, and I-shaped guide pad medial surface is ramp structure, the most outward-dipping, I-shaped
Guide pad medial surface longitudinal direction is provided with guide groove, and core rod is movably arranged on guide groove, die cavity is provided with core rod correspondence position and leads
Xiang Kong, when core rod is positioned at guide groove bottommost, core rod termination is inserted in pilot hole, during the demoulding, core rod from guide groove bottommost toward top
Abjection, when ramp effect, core rod the most from inside outwards moves, and makes core rod termination depart from pilot hole, completes the demoulding.This utility model
By using above-mentioned technology, I-shaped guide pad medial surface is set to ramp structure, core rod is movably arranged on this medial surface and leads
On groove, core rod termination is inserted in the pilot hole of die cavity, and after product injection terminates, die cavity under the action of the spring, moves up, band
Moving-mould-core is along guide groove upward sliding, and owing to guide groove itself is incline structure, core rod, while upwards, is also moved out relative to die cavity
Dynamic, core rod termination departs from the barb of product, completes the demoulding.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is partial enlargement structural representation of the present utility model.
In figure: 1-die cavity, 101-pilot hole, 102-the second groove, 2-press plates, 201-the first groove, 3-spring, 4-work
Word guide pad, 401-guide groove, 5-core rod.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is also
It is not limited only to this:
As shown in Figure 1-2, the mould structure of a kind of core pulling of the present utility model, join including die cavity 1 and with its activity
Closing the press plates 2 connected, be provided with cover half core upwards bottom described press plates 2, press plates 2 is symmetrically arranged on two with I-shaped guide pad
4, I-shaped guide pad 4 medial surface is ramp structure, the most outward-dipping, I-shaped guide pad 4 medial surface longitudinal direction
Being provided with guide groove 401, core rod 5 is movably arranged on guide groove 401, in order to improve the compactness that coordinates of core rod 5 and guide groove 401, and makes
Core rod 5 slides more flexible, accurate, prevents displacement, and core rod 5 termination is set to I-groove, passes through I-groove by this utility model
Being movably arranged in guide groove 401, die cavity 1 is provided with pilot hole 101 with core rod 5 correspondence position, core rod 5 is positioned at guide groove 401 end
During portion, core rod 5 termination is inserted in pilot hole 101, and during the demoulding, core rod 5 is deviate from toward top from guide groove 401 bottommost, makees on inclined-plane
Used time, core rod 5 the most from inside outwards moves, and makes core rod 5 termination depart from the product in pilot hole 101, completes the demoulding.
As it can be seen, for the ease of being departed from from press plates 2 by die cavity 1, this utility model has at press plates 2 upper surface
At least two the first groove 201, die cavity 1 lower surface correspondence position is provided with the second groove 102 of same number, and corresponding first is recessed
It is provided with spring 3, under the pressure of injection matched moulds, i.e. at press plates 2 upper surface in the space that groove 201 and the second groove 102 are formed
Time of completely closed with die cavity 1 lower surface, spring 3 is in compressive state.
As it can be seen, the work process of embodiment of the present utility model is as follows:
1) injecting plastic cement, pressurize in the die cavity 1 of mould by injection machine, cooling, and die sinking, owing to spring 3 is in compression
State, during die sinking, die cavity 1 is under the effect of spring 3, and along with die sinking direction moves up 15mm, core rod 5 is along with die cavity 1
Move up 15mm to die sinking direction, simultaneously because core rod 5 is movably arranged on guide groove 401, core rod 5 move up same
Time, it is upward sliding on guide groove 401, owing to I-shaped guide pad 4 inner surface is ramp structure, and same at upward sliding of core rod 5
Time, relative die cavity 1 is made motion inside-out, so that the inner termination of core rod 5 departs from the barb of product from horizontal direction, is prevented
Damage of product during die sinking, thus complete the knockout course of band barb product, finally by dynamic model face thimble up ejecting product and take
Go out, complete the production process of a cycle period.
This utility model is by this core pulling limited, and while die sinking, product disengaging die cavity is carried out during going out
Loosing core so that die sinking process is continuous, the finished product being once molded band barb produces, it is not necessary to carry out secondary punching again, reduces and produces
The production cost of product, effectively improves product efficiency, it is ensured that product quality.
