Description
Technical field
The present invention relates to injection mold technology, and in particular to a kind of crossbar guiding mechanism of injection mould slanted.
Background technology
Pitched roof mechanism is one of most common mechanism in injection mold, and the back-off position mainly solved on product can not normally take off
The problem of mould.It is first-class to include ejector retainner plate, slide, angle ejector rod, oblique top for common pitched roof mechanism at present, oblique top head by angle ejector rod with
Slide connects, and slide is installed on ejector retainner plate, and guide runner is formed with slide, and slide guide piece is arranged at angle ejector rod lower part, and slide guide piece can
Slided in guide runner.In product ejection process, in the vertical direction slide drives angle ejector rod and oblique top head to move upwards, at the same time
Slide guide piece slides in guide runner and then ensures that be buckled to position smoothly departs from oblique top head in the horizontal direction.However, some products
Back-off position also there are downward gradient (i.e. there are product stripping angle), need the slide of corresponding pitched roof mechanism at this time vertical
While direction drives angle ejector rod and the oblique top head to move upwards, also to cause angle ejector rod and oblique top head relative to ejector retainner plate along product
There is the action of slip in the direction (angle of the direction and ejector retainner plate is known as slope angle under oblique top) of draft angle, and so this could be fallen
Button bit smoothly demoulds.If product stripping angle is larger, slope angle also and then becomes larger under corresponding oblique top, and to cause product
The demoulding, slide is changeless to the active force of angle ejector rod in the vertical direction, then slope angle is bigger under oblique top, and slide is to oblique
Active force of the mandril in angle ejector rod vertical direction is also bigger, causes oblique top bad stability, easy bending is stuck or even has
Risk of breakage.
The content of the invention
The shortcomings that the purpose of the invention is to overcome prior art, a kind of reduction oblique top descending is provided for existing oblique top
Angle and then the crossbar guiding mechanism for improving oblique top stability.
To realize that goal of the invention the technical solution adopted by the present invention is：
The crossbar guiding mechanism of injection mould slanted, it is characterised in that including ejector retainner plate, oblique-top sliding seat and angle ejector rod, institute
State and slide guide runner is formed with ejector retainner plate, the oblique-top sliding seat is slidably mounted on the slide guide runner, the oblique-top sliding seat
In be formed with the inclined slide plate guide runner of right low left high, the lower end of the angle ejector rod is provided with slide slide guide piece, the slide slide guide
Piece is slidably mounted in the slide plate guide runner, and the inclined guiding rod through-hole of right low left high, institute are also formed with the oblique-top sliding seat
The acute angle size for being oriented to rod through-hole and the ejector retainner plate is stated more than the acute angle of the slide plate guide runner and ejector retainner plate folder
Angle size, described be oriented in rod through-hole are provided with oblique jacking guide bar.
Compared with prior art, used the oblique top of the present invention to substantially reduce the lower angle of slope of oblique top, also reduced tiltedly
Active force of the slide to angle ejector rod in angle ejector rod vertical direction is pushed up, so as to improve the stability of oblique top.
Brief description of the drawings
Fig. 1 is the pitched roof mechanism assembly structure diagram using the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, the invention will be further described.As shown in Figure 1, injection mold
Crossbar pitched roof mechanism, including it is Bottom clamp plate 8, the dynamic model 2 on the Bottom clamp plate 8, oblique on the dynamic model 2
Top 1, the angle ejector rod 6 and ejector retainner plate 4 of the connection oblique top first 1, wherein oblique top first 1 are used to be molded the back-off position of product, institute
State and crossbar guiding mechanism is installed on ejector retainner plate 4, the crossbar guiding mechanism includes an oblique-top sliding seat 5, the ejector retainner plate 4
On be formed with slide guide runner 41, the oblique-top sliding seat 5 is installed in the slide guide runner 41 and can be in slide guide runner 41
Slide, be formed with slide plate guide runner 52 in the oblique-top sliding seat 5, the lower end of the angle ejector rod 6 is provided with slide slide guide piece 51, described
Slide slide guide piece 51 is installed in the slide plate guide runner 52 and can be slided along slide plate guide runner 52, in the oblique-top sliding seat 5 also
It is formed with and is oriented to rod through-hole 53, slide plate guide runner 52 therein and guiding rod through-hole 53 is the high right end low dip of left end, and are oriented to
The acute angle size of rod through-hole 53 and ejector retainner plate 4 is more than the acute angle size of slide plate guide runner 52 and ejector retainner plate 4, wherein sliding
The acute angle of piece guide runner 52 and ejector retainner plate 4 is product stripping angle or oblique top descending slope, the guiding rod through-hole 53
In be provided with oblique jacking guide bar 3, one end of the oblique jacking guide bar 3 is fixed on the dynamic model 2, and the other end is fixed on described dynamic
On die holder plate 8.
The operation principle of the present invention is as follows：As shown in Figure 1, in 4 ejection process of ejector retainner plate, in the effect of other thimble rods
Under, product movement upwards synchronous with ejector retainner plate 4, and oblique-top sliding seat 5, angle ejector rod 6 and oblique top first 1 are transported upwards also with ejector retainner plate 4
Dynamic, at the same time, the slide slide guide piece 51 of 6 lower end of angle ejector rod slides to the right along slide plate guide runner 52 so that 6 He of angle ejector rod
Oblique top first 1 also follows slide slide guide piece 51 to be moved to the right relative to ejector retainner plate 4 or product, to realize oblique top first 1 and product
Back-off position depart from.The present invention is due to there is provided oblique jacking guide bar 3, and in 4 ejection process of ejector retainner plate, oblique-top sliding seat 5 can also be
Slided to the left under the action of oblique jacking guide bar 3, the direct effect of the action is so that angle ejector rod 6 and oblique top first 1 relative to thimble
Movement velocity is accelerated to the right for plate 4 or product.And be to realize to depart from the back-off position of product, oblique top first 1 is along product stripping angle
It is changeless to spend direction and need mobile minimum range, is drawn accordingly, pitched roof mechanism of the invention is relative to the prior art
Oblique top, the smaller that can design oblique top descending slope is vertical in angle ejector rod to angle ejector rod 6 this reduces oblique-top sliding seat 5
Active force on direction, so as to improve the stability of oblique top.
Preferred embodiment of the invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Need creative work to conceive according to the present invention and make 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 fall within the scope of protection of the present invention.
