As shown in Fig. 2, this oblique top is double to move towards mould structure, include caster 1 and male template 2, product is located at master mold
In space between plate 1 and male template 2, in 2 lower end of male template there is upper ejector retainner plate 22 and lower ejector retainner plate 23, have on product
There is buckle 3, which further includes a top oblique top 4 and bottom oblique top 5, and top oblique top 4 is located at buckle glue position, bottom
Oblique top 5 is located at buckle lower end, and top oblique top 4 is connected with the first ejection and drives component 6, and bottom oblique top 5 is connected with the second ejection
Drive component 7, in die sinking the first ejection drive component 6 upwards top so that bottom oblique top 5 slides abjection buckle glue position, the second top
Go out to drive component 7 upwards top so that bottom oblique top 5 slides abjection is buckled, what two oblique tops of bottom oblique top 5 and top oblique top 4 slided
Angle is in 90 degree of angles, as shown in figure 3, bottom oblique top 5 and top oblique top 4 move when sliding abjection towards both direction, oblique top bottom
There is 3 degree of draft angle between at the top of portion and oblique top, bottom oblique top 5 is made on product buckle 3, when ejection, this bottom
Portion's oblique top 5 slides down, and top oblique top 4 is turned left when ejection and slided, because being to eject simultaneously, bottom oblique top 5 can't
Bump against top oblique top 4, and also have 3 degree of draft angle at the top of oblique top bottom and oblique top, prevent from sliding and have some setbacks, when ejection centainly
When position, two oblique tops successfully deviate from product buckle 3, as shown in figure 4, the first ejection drives component 6 to include the first oblique top
8, two the first guide sleeves 9 of bar, the first guide sleeve support iron ring 10, the first snap ring 11, the first Universal-head 12, the first slide guide piece 13 and
First tilted footstock 14, the lower end of the first angle ejector rod 8 are mounted on the first tilted footstock 14 by the first Universal-head 12, the first slide guide piece 13
On, the first guide sleeve 9, the first guide sleeve support iron ring 10, the first snap ring 11 are sleeved on the upper of the first angle ejector rod 8, the first angle ejector rod 8 it is upper
End is connect with top oblique top 4.Here the first guide sleeve 9 can ensure the ejection direction of the first angle ejector rod 8, the first guide sleeve support iron ring
10 and 11 sets of the first snap ring can be used for fixing the position of the first guide sleeve 9, the first tilted footstock 14 can be used for driving first tiltedly
Mandril 8 moves, and the second ejection drives component 7 to include 15, two the second guide sleeves 16 of the second angle ejector rod, the second guide sleeve support iron ring
17th, the second snap ring 18, the second Universal-head 19, the second slide guide piece 20 and the second tilted footstock 21, the lower end of the second angle ejector rod 15 lead to
Cross the second Universal-head 19, the second slide guide piece 20 is mounted on the second tilted footstock 21, the second guide sleeve 16, the second guide sleeve support iron ring
17th, the second snap ring 18 is sleeved on the upper of the second angle ejector rod 15, and the upper end of the second angle ejector rod 15 is connect with bottom oblique top 5, the first oblique top
There is intersecting angle between 8 and second angle ejector rod 15 of bar.Similary second guide sleeve 16 can ensure the ejection side of the second angle ejector rod 15
To 18 sets of 17 and second snap ring of the second guide sleeve support iron ring can be used for fixing the position of the second guide sleeve 16, the second tilted footstock
21 can be used for that the second angle ejector rod 15 is driven to move.
Mold is under the action of injection molding machine ejection during work, and upper ejector retainner plate 22 and lower ejector retainner plate 23 are with 4 He of top oblique top
Bottom oblique top 5 is up pushed up together, because the angle that two oblique tops slide, in 90 degree of angles, two oblique tops are respectively toward both direction
Movement is to the left respectively and is moved down, and top oblique top 4 and bottom oblique top 5 also have 3 degree of draft angle, prevents two tiltedly
Top, which is slided, to have some setbacks, and when certain position is ejected, top oblique top 4 and 5 liang of oblique top binding faces of bottom oblique top are more and more remote, do not do mutually
It relates to, bottom oblique top 5 successfully deviates from product buckle 3, and top oblique top 4 also successfully avoids the glue position of buckle, makes the smooth depanning of product.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, defined range that however, it does not deviate from the spirit of the invention.
