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 two-way oblique core drawing mechanism of asymmetric provided in this embodiment, includes the cunning of the asymmetric setting in both sides
Block 41, sliding pin 42, slide core 43 and core mold insert 45.Sliding pin 42 per side corresponds to the slide core across side where it
The end is simultaneously actively locked on the sliding block 41 of the side so that it can drive slide core 43 in corresponding cunning by the hole of 43 one end
It is slided on block 41.And the inner hole of corresponding with its place side core mold insert of the other end 45 of each slide core 43 and can phase
Mutually sliding.Wherein, the two-way oblique core drawing mechanism of the asymmetric of the present embodiment, which mainly coordinates, carries out the asymmetrical both sides inclined hole of product
Molding, thus be equipped at least a pair of of slide core 43 in both sides respectively, the axis of the slide core 43 of both sides is different flat
On face, and each slide core 43 is in respectively a default angle with horizontal direction.
Refering to what is shown in Fig. 2, the two-way oblique core drawing mechanism of the asymmetric of the present embodiment is equipped with two pairs of slide cores 43, where
Core-pulling mechanism be asymmetricly arranged respectively in both sides, corresponding two pairs of slide cores 43 are also disposed at the not homonymy of mechanism,
That is the mechanism structure of both sides is identical, but between be in an angle.In conjunction with Fig. 2, the cunning of the axis and right side of the slide core 43 in left side
Block enters the axis of son 43 not on the same line, and the two mutually has angle, similarly, corresponding sliding block 41, sliding pin 42 and core
Mold insert 45 also mutually at the same angle, the multi-direction difference of inclined hole in the not homonymy Different Plane so as to realize shaped article
The core pulling of angle operates.In the present embodiment, horizontal direction is in two slide cores 43 and the Fig. 2 on right side default folder
The size at angle is respectively A and B, and respectively in the both sides of sliding block 41, and positioned at two slide cores 43 and horizontal direction in left side
The size for the default angle for being in is respectively C and D, and respectively in the both sides of sliding block 41, wherein the value of A, B, C and D can be according to need
It is set as identical or different.
Referring again to Fig. 1 and Fig. 2, two sliding blocks 41 in the present embodiment can be slided with respect to Bottom clamp plate 4 respectively, and core
Mold insert 45 is fixed on by mold insert screw 14 on Bottom clamp plate 4.Wherein, sliding block 41 is equipped with the cunning vertical relative to sliding block itself
Dynamic slot 412, two slide cores 43 carry out opposite sliding respectively along the sliding groove 412 when for core pulling.Due to the present embodiment
In, the horizontal line R at an angle in the slide core 43 and Fig. 1 on right side, thus the endoporus of corresponding core mold insert 45 is also oblique
To.
Shown in Fig. 1 and 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 is equipped with the sliding groove 412 and water vertical relative to sliding block itself
Flat enters pilot trench 411.Wherein, enter slide core 43 of the pilot trench 411 for housing respective side.Refering to what is shown in Fig. 4, slide core 43
The one end being located at into pilot trench 411 is equipped with location hole 432, and passes through the location hole 432 and the sliding pin 42 in sliding groove 412
It is connected so that slide core 43 can be slided along sliding groove 412 relative to sliding block 41 by sliding pin 42.And sliding block
The other end (namely entering at where sub- guide surface 433) and the endoporus of core mold insert 45 for entering son 43 are slidably matched, and two sliding blocks
It is in a default angle with the horizontal direction in Fig. 2 to enter son 43 so that slide core 43 is located at the cavity where product to be formed
Both sides can be respectively formed two slanting holes, the sliding block 41 of the asymmetric setting of both sides, sliding pin 42, slide core simultaneously
43 and core mold insert 45 constitute the entirety of two-way oblique core drawing mechanism.
Wherein, the default angle of each of the present embodiment can be respectively set to any one between 0 degree to 30 degree as needed
Value, or can also be arranged as required to be 30 degree.In a further preferred embodiment, between each slide core 43 and horizontal direction
Default angle can be respectively set to 15 degree, then the product both sides of final molding will tool there are two angle be simultaneously 30 degree oblique
Hole.Certainly, different default angle values can be arranged as required to as different value, such as one of A, B, C and D or partly or entirely
It is identical or different, or in which one of or be partly or entirely set as 15 degree.Similarly, the axis of the slide core 43 on right side and its institute
The angle R of Bottom clamp plate 4 be also any one value between 0 degree to 30 degree, or can also be arranged as required to be 30 degree or 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.
