Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.As shown in Figs. 1-5, injection mold
It is dark to take out core-pulling mechanism, including inclined guide pillar 1, sliding block 2 and it is dark take out insert 3, the inclined guide pillar 1 is fixed on cover half, the sliding block 2 with
Dark insert 3 of taking out is mounted on dynamic model, drive block 4 is connected between the sliding block 2 and the dark pumping insert 3, as shown in figure 3, institute
It states one end that drive block 4 is connected with the dark pumping insert 3 and is formed with slider guide 41, be formed with the cunning being obliquely installed on the slider guide 41
Slot 411, the sliding slot 411 are located at the front and back two sides of the slider guide 41, and the dark bottom for taking out insert 3 is formed with and the slide guide
The mounting groove 31 that block 41 cooperates, the inwardly protruding formation fixture block 32 in the notch two sides of the mounting groove 31, as shown in figure 5, the peace
Tankage 31 is obliquely installed with fixture block 32, and the slider guide 41 is located in the mounting groove 31, and the fixture block 32 is located at the cunning
In slot 411.When demoulding, inclined sliding slot 411 converts the dark core pulling obliquely for taking out insert 3 for the horizontal movement of drive block 4 and transports
It is dynamic, realize product and the dark disengaging for taking out insert 3.
In above-mentioned technical proposal: being fixed with pin 5 on the dynamic model, the end of the pin 5 is fixed with thimble 6, described
Dark take out is formed with through-hole of threading a needle in insert 3, the thimble 6 be located at it is described thread a needle in through-hole, when molding 6 head of thimble end face
It is generally aligned in the same plane with the dark upper surface for taking out insert 3, in order to avoid extra aperture is caused to product.Thimble 6 is fixed by pin 5
On dynamic model, installing and dismounting is more convenient.When demoulding, thimble 6 is fixed, and dark insert 3 of taking out moves obliquely, thimble 6 and dark
It takes out insert 3 and generates relative motion, the head of thimble 6 gradually passes through the dark upper surface for taking out insert 3 and ejects product, so that producing
Product are partially disengaged with dark insert 3 of taking out, and product demoulding can occur and lose since package power is excessive when preventing from secretly taking out 3 direct core pulling of insert
The phenomenon that losing.
In above-mentioned technical proposal: as shown in figure 4, the dark bottom for taking out insert 3 is also formed with the arc with the pin 5 cooperation
Shape slot 33.The arc groove 33 is avoided the mounting groove 31 and is arranged, and core pulling touches the pin to the dark pumping insert 3 obliquely
When 5, the arc groove 33 fits with the pin 5 just.
In above-mentioned technical proposal: as shown in figure 3, one end that the drive block 4 is connect with the sliding block 2 is formed with boss 42,
The right side of the boss 42 is formed with card slot 43, and the bottom cooperation of the sliding block 2 is formed with groove and convex block.Boss 42 is matched with groove
It closes, the cooperation of card slot 43 and convex block is so that drive drive block 4 moves synchronously when mobile sliding block 2.
In above-mentioned technical proposal: the bottom of the sliding block 2 is fixed with fixed block 7, described in one end of the fixed block 7 is stretched out
Sliding block 2, the part that the fixed block 7 stretches out sliding block 2 are formed with slanting guide pillar hole, and when molding, the inclined guide pillar 1 passed through the inclined guide pillar
Hole.
In above-mentioned technical proposal: being also formed with the through-hole 44 of bar shaped on the drive block 4, the mandril on ejector retainner plate is facilitated to pass through
Dynamic model and drive block 4.
In above-mentioned technical proposal: as shown in Fig. 2, also connecting between the bottom of the sliding block 2 and the dark bottom for taking out insert 3
It is connected to supporting block 8, shown in Fig. 2 is the embodiment of one of drive block 4 and the arrangement mode of supporting block 8, as shown in figure 4,
The dark bottom for taking out insert 3 is formed with the square groove 34 with the supporting block 8 cooperation.The supporting block 8 cooperates with square groove 34
One end bevel, as shown in figure 5, being accordingly formed with slide guide inclined-plane 341 on square groove 34.Supporting block 8 plays dark insert 3 of taking out
Support and guiding role.
The course of work of the invention is as follows, and active and inactive mold separates after injection molding, and cover half drives inclined guide pillar 1 to move up, 2 quilt of sliding block
Inclined guide pillar 1 drives towards 2 core pulling direction horizontal movement of sliding block, and drive block 4 is moved synchronously with sliding block 2, while secretly being smoked in insert 3
Fixture block 32 makees core pulling campaign obliquely along inclined sliding slot 411.In the above process, since thimble 6 is fixed, insert is secretly taken out
3 obliquely core pulling when, thimble 6 and dark insert 3 of taking out generate relative motion, and the head of thimble 6 gradually passes through the dark upper table for taking out insert 3
Face ejects product, so that product is partially disengaged with dark insert 3 of taking out.Fixture block 32 continues on sliding slot 411 and makees the fortune of core pulling obliquely
Dynamic, until product and dark insert 3 of taking out completely disengage, core pulling is finished.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution should all be fallen within the scope of protection of the present invention.
