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 the Ejection Mechanism of Injection Mould technical field, be specially the ejecting mechanism of the narrow and small dark die cavity in space.
Background technology
The ejecting mechanism of the dark die cavity that existing space is narrow and small, make the fork ramp-roof structure of three joint segmenteds, the requirement on machining accuracy of each link position is than higher, when big shaping area is arranged on oblique top, the injection pressure that bears is corresponding have been increased a lot, it is more to make that the position length of first section of oblique top will increase, its complex structure, and it is big that manufacture difficulty is installed.
Summary of the invention
At the problems referred to above, the invention provides the ejecting mechanism of the narrow and small dark die cavity in space, it is simple in structure, installation is easily manufactured.
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, be set with roller on the described turning cylinder, the external power set of described turning cylinder, 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, its top one side was close to described punch core after described oblique top ran through described punch connecting plate, 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 the inclined-plane with the face that combines with described punch core.
It is further characterized in that: described oblique top is fitted near side of workpiece and punch connecting plate, below the joint place, is the inclined-plane bayonet fittings between described oblique top and the described punch connecting plate, leaves the slip spacing between about two inclined-plane bayonet sockets of cooperation.
After adopting said structure of the present invention, oblique top ejects in the process of workpiece, drives by external power set, oblique top is finished translation in the driving of roller, clamp structure by the outside makes oblique top separate with workpiece, finishes the process that ejects workpiece, and total is simple, installation is easily manufactured.
Description of drawings
Fig. 1 is the matched moulds status architecture schematic diagram of front view of the present invention;
Fig. 2 is that the workpiece of front view of the present invention ejects the structural scheme of mechanism after finishing.
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, do not draw among the figure), oblique top 3 runs through punch connecting plate 4, turning cylinder 8 is equipped with in oblique top 3 bottoms, be set with roller 9 on the turning cylinder 8, turning cylinder 8 external power set (belong to existing mature technology, do not draw among the figure), 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 punch connecting plate 4 its top one side applying punch cores 2 of back, 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 fitted near workpiece 12 1 sides and punch connecting plate 4, below the joint place, be the inclined-plane bayonet fittings between oblique top 3 and the punch connecting plate 4, two inclined-plane bayonet sockets of cooperation leave slip spacing 13 between up and down.Top one side of oblique top 3 is close to punch core 2 during matched moulds, 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.The direction of arrow is the translation direction that workpiece 12 ejects oblique top 3 in the process among Fig. 2.
Its operation principle is as follows: when needs eject workpiece 12, after concave die cavity 1 breaks away from, the driving mechanism of needle plate bottom, the end rises, drive oblique top 3, workpiece 12 rises together, top and punch core 2 until oblique top 3 break away from fully, driving turning cylinder 8 by external power set afterwards rotates, roller 9 rotates in the rectilinear orbit of roller mount 7, because the middle part of oblique top 3 and a side and the punch core 2 of bottom leave the gap, oblique top 3 is finished translation under the driving of roller 9, until a side of the middle part of oblique top 3 and the bottom punch core 2 of fitting fully, because workpiece 12 has special mechanism to carry out clamping location (belonging to existing mature technology), so oblique top 3 is separated with workpiece 12, finishes the process that ejects workpiece 12.
Claims (2)
