Abstract
The invention discloses an ejecting mechanism of a small-space deep cavity, which has the advantages of simple structure and convenient mounting and manufacturing. The mechanism comprises a concave mold cavity, a convex mold core, an inclined ejector, a convex mold connecting plate, an ejector retainer plate, an ejector base plate and a lower driving mechanism of the ejector base plate, wherein the inclined ejector passes through the convex mold connecting plate. The mechanism is characterized in that the bottom of the inclined ejector is provided with a rotation shaft, rollers are sleeved on the rotation shaft, the rotation shaft is externally provided with a power device, the rollers are supported in linear tracks of roller seats, and the roller seats are fastened on the ejector base plate and the ejector retainer plate; after the inclined ejector passes through the convex mold connecting plate, one side at the top of the inclined ejector is appressed to the convex mold core; and one side of the combination parts of the middle part of the inclined ejector and the convex mold core and the convex mold connecting plate, which is away from a workpiece, is reserved with an interval, while the surfaces combined with the convex mold core at the other sides are inclined planes.
Description
Technical field
The present invention relates to Ejection Mechanism of Injection Mould technical field, be specially the ejecting mechanism of the dark die cavity of narrow space.
Background technology
The ejecting mechanism of the dark die cavity of existing narrow space, make the fork ramp-roof structure of three joint segmenteds, the requirement on machining accuracy of each link position is higher, while having larger shaping area in oblique top, corresponding having increased much of injection pressure of bearing, the position length of oblique top first paragraph to be increased more, its complex structure, and it is large that manufacture difficulty is installed.
Summary of the invention
For the problems referred to above, the invention provides the ejecting mechanism of the dark die cavity of narrow space, it is simple in structure, it is easily manufactured to install.
Its technical scheme is such: it comprises concave die cavity, punch core, oblique top, punch connecting plate, face needle plate, end needle plate, end needle plate lower drive, and described oblique top runs through described punch connecting plate,
It is characterized in that: turning cylinder is equipped with in described oblique top bottom, on described turning cylinder, be set with roller, described turning cylinder external connection power device, described roller wheel bearing is in the rectilinear orbit of roller mount, described roller mount is anchored on needle plate of the described end, face needle plate, after described oblique top runs through described punch connecting plate, its top one side is close to described punch core, the middle part of described oblique top and described punch core, described punch connecting plate binding site away from a side of workpiece leave spacing, opposite side is inclined-plane with the face combining with described punch core.
It is further characterized in that: described oblique top, near a side of workpiece and the laminating of punch connecting plate, below joint place, is inclined-plane bayonet fittings between described oblique top and described punch connecting plate, and two inclined-plane bayonet sockets of cooperation leave slip spacing between up and down.
Adopt after said structure of the present invention, in the process of lifter ejection workpiece, by external connection power device, drive, oblique top completes translation in the driving of roller, by outside clamp structure, make oblique top separated with workpiece, complete the process that ejects workpiece, total is simple, it is easily manufactured to install.
Accompanying drawing explanation
Fig. 1 is the matched moulds status architecture schematic diagram of front view of the present invention;
Fig. 2 is the structural scheme of mechanism after the workpiece of front view of the present invention has ejected.
The specific embodiment
See Fig. 1, Fig. 2, the present invention includes concave die cavity 1, punch core 2, oblique top 3, punch connecting plate 4, face needle plate 5, end needle plate 6, end needle plate lower drive (belongs to existing mature technology, not shown in FIG.), oblique top 3 runs through punch connecting plate 4, turning cylinder 8 is equipped with in oblique top 3 bottoms, on turning cylinder 8, be set with roller 9, turning cylinder 8 external connection power devices (belong to existing mature technology, not shown in FIG.), roller 9 is supported in the rectilinear orbit of roller mount 7, roller mount 7 is anchored on end needle plate 6, face needle plate 5, oblique top 3 runs through rear its top one side laminating punch core 2 of punch connecting plate 4, the middle part of oblique top 3 and punch core 2, punch connecting plate 4 binding sites leave spacing away from a side of workpiece 12, oblique top 3 is near workpiece 12 1 sides and 4 laminatings of punch connecting plate, below joint place, between oblique top 3 and punch connecting plate 4, it is inclined-plane bayonet fittings, between two inclined-plane bayonet sockets coordinating are upper and lower, leave slip spacing 13.During matched moulds, top one side of oblique top 3 is close to punch core 2, and a side and the punch core 2 of the middle part of oblique top 3 and bottom leave spacing 10, and at the offside that leaves spacing 10, oblique top 3 is inclined-plane 11 with the faying face of punch core 2.In Fig. 2, the direction of arrow is the translation direction of oblique top 3 in workpiece 12 ejection process.
Its operation principle is as follows: when needs eject workpiece 12, after concave die cavity 1 departs from, the driving mechanism of needle plate bottom, the end rises, drive oblique top 3, workpiece 12 rises together, until the top of oblique top 3 and punch core 2 depart from completely, by external connection power device, drive turning cylinder 8 to rotate afterwards, roller 9 rotates in the rectilinear orbit of roller mount 7, because the middle part of oblique top 3 and a side of bottom and punch core 2 leave gap, oblique top 3 completes translation under the driving of roller 9, the punch core 2 until a side of the middle part of oblique top 3 and bottom is fitted completely, because having special mechanism, workpiece 12 carries out clamping position (belonging to existing mature technology), therefore oblique top 3 is separated with workpiece 12, complete the process that ejects workpiece 12.
