Description

A kind of slanted ejecting mechanism
Technical field
The utility model relates to injection moulding class technical field of mold, is specifically related to a kind of slanted ejecting mechanism.
Background technology
Present product construction design becomes increasingly complex, and often will carry out slant-top core-pulling, and the ability demoulding, needs very large core pulling distance during the complete break away from moulds of some product, and it is the angle that (1) strengthens oblique top that current solution party strengthens method; (2) ejection stroke of ejector retainner plate is strengthened.But while oblique top angle increases, oblique top is to the frictional force of inclined top guide block also along with increase, and the contact surface of oblique top and inclined top guide block with regard to the burn that easily rubs, and then destroys the stability of oblique top motion; The ejection stroke strengthening ejector retainner plate can strengthen mould bases on the one hand thus increase die cost, also can be subject to the restriction of the maximum die sinking of injection molding machine and ejection stroke on the other hand.
Utility model content
The utility model provides a kind of slanted ejecting mechanism, and structure is simple, can the mechanical relationship of optimization and upgrading tradition lifter ejecting mechanism, while increase oblique top angle, effectively reduces the torsion of tilted footstock to oblique top, improves the stability of oblique top motion.
In order to achieve the above object, the technical scheme that the utility model adopts is, a kind of slanted ejecting mechanism, comprise oblique top, tilted footstock, oblique top slide block, inclined top guide block and guiding mechanism, described oblique top bottom is provided with oblique top slide block, this oblique top slide block is positioned at the rail groove of tilted footstock and is slidably connected with tilted footstock, and oblique top is provided with inclined top guide block, and described oblique top slide block connects one group of guiding mechanism being parallel to lifter ejection direction for shifting the torsion of described tilted footstock to oblique top.
Further, described guiding mechanism comprises guide pillars and bushes, and described guide pillar is sleeved on oblique top slide block by guide pin bushing, and described guide pillar is fixed on base plate through oblique top slide block and tilted footstock.
Further, described guide pillar comprises two and is arranged in parallel.
Further, described tilted footstock is anchored on ejector retainner plate and thimble fixed head and is formed on the whole.
The utility model is by adopting technique scheme, and compared with prior art, tool has the following advantages:
The utility model is by increasing by one group of guiding mechanism at oblique top slide block, the harmful torsion acted on by tilted footstock in oblique top moves on guiding mechanism, effectively solve large-angle inclined apical axis heart angle lifter ejection easily and inclined top guide block friction burn and stuck problem of moving.This kind of mechanism under rational ejection stroke, can obtain large core pulling distance, meets the production requirement of the very large core pulling distance product of needs, and this mechanism has compact conformation, saves space simultaneously, reduces the advantage of mould bases size.
Accompanying drawing explanation

Fig. 2 is sectional view of the present utility model;
Fig. 3 is the sectional view under the utility model is in the state of ejecting;
Fig. 4 is the utility model lifter ejecting mechanism force analysis schematic diagram front with improvement.
Detailed description of the invention
Now with detailed description of the invention, the utility model is further illustrated by reference to the accompanying drawings.As shown in Figure 1, Figure 2, Figure 3 shows, a kind of slanted ejecting mechanism, comprise oblique top 1, tilted footstock 2, oblique top slide block 3, inclined top guide block 4 and guiding mechanism 5, described oblique top slide block 3 is positioned at the rail groove of tilted footstock 2 and tilted footstock 2 is slidably connected, oblique top is provided with inclined top guide block, described inclined top guide block 4 is through oblique top pilot hole, and described oblique top slide block 3 connects one group of guiding mechanism being parallel to lifter ejection direction for shifting the torsion of described tilted footstock 2 pairs of oblique tops 1.Described guiding mechanism comprises guide pillar 51 and guide pin bushing 52, and described guide pillar 51 is sleeved on oblique top slide block 3 by guide pin bushing 52, and described guide pillar 51 is fixed on base plate 8 through oblique top slide block 3 and tilted footstock 2.Described guide pillar 51 is provided with two and is arranged in parallel, and described tilted footstock 2 is anchored on ejector retainner plate 6 and thimble fixed head 7 is formed on the whole.
See Fig. 4, when improving the lifter ejection of pre-structure, tilted footstock 2 pairs of oblique tops 1 apply the torsion F2 being decomposed into effective push F1 and the vertical oblique top direction of motion being parallel to the oblique top direction of motion to lifting force F, F.Pass through lever equilibrium condition, inclined top guide block 4 need apply pressure F3 to oblique top, F3=F2* L1/L2=Sina* F* L1/L2, when knowing that L1 is larger or a is larger by formula, F3 is also larger, thus inclined top guide block 4 couples of oblique top 1 frictional force f are also larger, when f reaches certain numerical value, the contact surface of oblique top 1 and inclined top guide block 4 with regard to the burn that easily rubs, and then destroys the stability of oblique top motion, so the lifter ejecting mechanism oblique top axle center angle a improving pre-structure generally gets within 10 °.A kind of slanted ejecting mechanism of the utility model, by increasing by one group of guiding mechanism 5 in oblique top slide block, effectively can forward the torsion F2 of tilted footstock 2 pairs of oblique tops 1 on guide pillar 51 to, be applied to oblique top and only have effective push F1.Because this torsion F2 acts directly on the sliding surface of guide pillar 51 and guide pin bushing 52, without lever phenomenon, frictional force f=Sina* F between guide pillar 51 and guide pin bushing 52, than the few L1/L2 of ramp-roof structure before improvement doubly, therefore the about L1/L2 of pitched roof mechanism is doubly before the comparable improvement of oblique top axle center angle a for obvious frictional force f.
A kind of slanted ejecting mechanism of the utility model, the harmful torsion acted on by tilted footstock in oblique top moves on guiding mechanism, effectively solve large-angle inclined apical axis heart angle lifter ejection easily and inclined top guide block friction burn and stuck problem of moving, under rational ejection stroke, obtain large core pulling distance, meet the production requirement of the very large core pulling distance product of needs, in conjunction with knowhow, under guarantee guide pillar some strength, maximum desirable 30 ° of the oblique top axle center angle a of wide-angle slanted ejecting mechanism, this mechanism has compact conformation, save space, reduce the advantage of mould bases size, there is very large promotion prospect.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
