Below with reference to the attached drawing of the present invention, technical solution in the embodiment of the present invention carries out clear, complete description
And discussion, it is clear that as described herein is only a part of example of the present invention, is not whole example, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained without making creative work
Example, belongs to protection scope of the present invention.
For the ease of the understanding to the embodiment of the present invention, make further by taking specific embodiment as an example below in conjunction with attached drawing
It illustrates, and each embodiment does not constitute the restriction to the embodiment of the present invention.
As shown in Figure 1, the outside side core-pulling mechanism of diclinic provided in this embodiment, including sliding block 41, sliding pin 42, sliding block enter
Son 43 and core mold insert 45.Sliding pin 42 passes through the hole of 43 one end of slide core and the end is actively locked on sliding block 41,
Allow it that slide core 43 to be driven to be slided on sliding block 41.The inner hole of the other end and core mold insert 45 of slide core 43
And it can mutually slide.Wherein, the outside side core-pulling mechanism of the diclinic of the present embodiment mainly coordinates two-way inclined hole to be molded, thus equipped with extremely
Few a pair of slide core 43, and each slide core 43 and horizontal direction are in a default angle.Wherein, the cunning in the present embodiment
Block 41 is obliquely set on Bottom clamp plate 4, and sliding block 41 is R relative to the angle of inclination of Bottom clamp plate 4.Similarly, core mold insert 45
Endoporus also tilted with respect to Bottom clamp plate 4, angle of inclination is identical with sliding block 41 namely the inclination of slide core Bottom clamp plate relatively
Angle is also identical as sliding block.
Refering to what is shown in Fig. 2, the outside side core-pulling mechanism of the diclinic of the present embodiment is equipped with a pair of of slide core 43, and slide core
43 are arranged at the same side of mechanism, and the default angle of 43 relative level of slide core is A, and two slide cores 43 are with respect to water
The default corner dimension of plane may be the same or different, but two slide cores and not parallel, and carry out phase can be corresponded to by changing mechanism in this way
Core pulling to 4 inclined two different angles of Bottom clamp plate, to realize the core pulling behaviour of inclined two different angles in the same side
Make.
Referring again to Fig. 1 and Fig. 2, the sliding block 41 in the present embodiment can be slided with respect to Bottom clamp plate 4, and core mold insert 45 is logical
Mold insert screw 14 is crossed to be fixed on Bottom clamp plate 4.Sliding block 41 is equipped with a vertical sliding groove 412, two sliding blocks when for core pulling
Enter son 43 and carries out opposite sliding respectively along 412 both sides of sliding groove.
Shown in Fig. 1,3, the side of sliding block 41 is equipped with slanting guide pillar hole 46 and passes through the slanting guide pillar hole 46 and one
Inclined guide pillar 31 is slidably matched (referring to Fig. 7), and the other side of sliding block 41 enters pilot trench equipped with vertical a sliding groove 412 and level
411.Wherein, enter pilot trench 411 for housing above-mentioned slide core 43.Refering to what is shown in Fig. 4, slide core 43 is located at into pilot trench
411 one end is equipped with location hole 432, and is coordinated with the sliding pin 42 in vertical sliding groove 412 by location hole 432 and connected
It connects so that slide core 43 can be slided along sliding groove 412 relative to sliding block 41 by sliding pin 42.And slide core 43
The other end (namely entering at where sub- guide surface 433) and the endoporus of core mold insert 45 be slidably matched, and two symmetrical sliding blocks
It is in a default angle respectively with horizontal direction to enter son 43 so that two slide cores 43 are located at the cavity where product to be formed
One end form the inclined holes of slanting two angles.
Wherein, the default included angle A in the present embodiment can be arranged as required to as any one value between 0 degree to 30 degree, or
It can be arranged as required to be 30 degree.In a further preferred embodiment, the default angle between slide core 43 and horizontal direction
Be 15 degree, then the product of final molding will have there are two angle be 30 degree inclined hole.Two 43 relatively horizontal orientations of slide core
Angle can be identical or different, similarly, sliding block 41 can also basis relative to the size of the angle of inclination R of Bottom clamp plate 4
It needs any one value being set as between 0 degree to 30 degree or is 30 degree, or be further preferably set as 15 degree.
Shown in Fig. 4, both sides are divided up and down at the 432 place end of location hole of the slide core 43 provided in the present embodiment
She You be not parallel enter sub- plane 431, enter sub- plane 431 and matched with the pilot trench 411 that enters of sliding block in Fig. 3 41 so that slide core
Situations such as being not in overturning while pilot trench 411 can be entered relatively and influence core pulling.
In addition, referring again to shown in Fig. 4, the other end of slide core 43 is equipped with into sub- guide surface 433 in the present embodiment, is entered
Sub- guide surface 433 and the shape of the endoporus of core mold insert 45 match.The section for entering sub- guide surface 433 in the present embodiment is circle
Shape, in other preferred embodiments, enter sub- guide surface 433 section can also be arranged as required to for regular polygon, ellipse or its
His irregular polygonal shape.
After the outside side core-pulling mechanism assembly of the diclinic, core mold insert 45 is fixed on by mold insert screw 14 on Bottom clamp plate 4；
Slide core 43 be mounted on sliding block 41 on entering in pilot trench 411, enter sub- plane 431 and enter pilot trench 411 lower planes match merge
Slidably, sliding pin 42 passes perpendicularly through sliding groove 412 and is interference fitted with location hole 432；Enter sub- guide surface 433 and core mold insert
45 inner holes are in mutually slidably included angle A with horizontal direction (with reference to figure 2).
When the outside side core-pulling mechanism of the diclinic works, with reference to figure 1, Fig. 2, before core pulling, sliding block 41 and 45 phase of core mold insert
Contact, at this point, the left end of slide core 43 is located in cavity for processing the outside side opening of diclinic.It needs to carry out after formed product
When the demoulding of the outside side opening of diclinic, by the power of outer bound pair slanting guide pillar hole 46, sliding block 41 is whole to be moved sliding block 41 toward the directions K, sliding
Block 41 drives sliding pin 42, sliding pin 42 that slide core 43 is driven to move right, and it is oblique that slide core 43 prolongs itself guide direction
Movement, the then sliding in sliding groove 412 of sliding pin 42.State after the completion of core pulling is as shown in Figures 5 and 6, at this point, sliding block 41 with
Core mold insert 45 is separated, and slide core 43 is located at one end of formed product cavity completely into type under the drive of sliding block
In the endoporus of core mold insert 45, the core pulling operation of the outside side opening of diclinic is preferably completed.
As shown in fig. 7, the present embodiment also provides a kind of diclinic core-pulling die outward, including above-mentioned diclinic is taken out outward
Core mechanism further includes top clamping plate 2, solid plate 3, Bottom clamp plate 4, and solid plate 3 is fixed on top clamping plate 2, under solid plate 3
Side is equipped with fixed mold 9, and Bottom clamp plate 4 is equipped with dynamic mould core 10, and fixed mold 9 and the matching of dynamic mould core 10 form cavity,
Solid plate 3 is equipped with inclined guide pillar 31 and is slidably matched with slanting guide pillar hole 46, is set between solid plate 3, Bottom clamp plate 4 with driving
