Abstract
The utility model discloses a kind of adaptive injection head, including injection head, upper contiguous block, lower connecting block, limited block, jumper bar and bushing, wherein, limited block is semi-cylindrical, and its section is in concave；The section of upper contiguous block and lower connecting block is in "convex" shaped, it is formed by stacking up and down by different size of two disks, the upper surface of upper contiguous block is fixedly connected with jumper bar, and the upper surface of lower connecting block is fixedly connected with injection head, and upper contiguous block contacts setting with the lower surface of lower connecting block；Limited block is arranged on the side of contiguous block and lower connecting block, and contiguous block and lower connecting block are superscribed in the recess of limited block, and limited block coordinates with upper contiguous block and lower connecting block gap respectively；Coordinated by the gap of all parts, upper connector and lower connector is floated with respect to plane, due to the automatic adjusument of injection head, then improved the precision between injection head and barrel again, ensure that material is not revealed without being further added by sealing ring.
Description
Technical field
Semiconductor production field is the utility model is related to, more particularly to a kind of adaptive injection head.
Background technology
In conventional traditional semiconductor packages production, the jumper bar of injection head and press is connected by screw element, with
The position of barrel on mould is corresponding, can not accomplish perfect matching, so the size of injection head and the size of barrel can not essences
Standard coordinates, and can only be coordinated by injection head and barrel gap, the gap between injection head and barrel needs just to fill out by sealing ring
Fill, like this, injection head moves back and forth, and the mainly friction between barrel and sealing ring, the loss to sealing ring is very
It is serious, it is necessary to frequent replacing sealing ring.
Utility model content
The defects of existing for above prior art, main purpose of the present utility model are overcome the deficiencies in the prior art
Part, a kind of adaptive injection head, including injection head, upper contiguous block, lower connecting block, limited block, jumper bar and bushing are disclosed,
Characterized in that,
The limited block is semi-cylindrical, and its section is in concave；
The section of the upper contiguous block and the lower connecting block is in "convex" shaped, by different size of two disks
Under be formed by stacking, the upper surface of the upper contiguous block is fixedly connected with the jumper bar, the upper surface of the lower connecting block with it is described
Injection head is fixedly connected, and the upper contiguous block contacts setting with the lower surface of the lower connecting block；
The limited block is arranged on the side of the upper contiguous block and the lower connecting block, is wrapped in the recess of the limited block
The upper contiguous block and the lower connecting block are wrapped up in, the limited block is matched somebody with somebody with the upper contiguous block and the lower connecting block gap respectively
Close.
Further, the limited block is at least provided with one piece.
Further, the limited block is two pieces.
Further, the upper surface inside the limited block to lower surface distance be equal to the upper contiguous block and it is described under
The height of contiguous block lower disc and.
Further, the overall diameter of the bushing is less than the diameter of the injection head.
The beneficial effect that the utility model obtains：
Coordinated by the gap of all parts, upper connector and lower connector is floated with respect to plane, can improve
The position relationship of the fit precision of injection head and barrel, automatic regulation injection head and barrel, due to the automatic adjusument of injection head,
The precision between injection head and barrel is then improved again, ensures that material is not revealed without being further added by sealing ring.
Brief description of the drawings
Fig. 1 is a kind of structural representation of adaptive injection head of the utility model；
Fig. 2 is the front view of limited block；
Reference is as follows：
1st, injection head, 2, upper contiguous block, 3, lower connecting block, 4, limited block, 5, jumper bar, 6, bushing.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with the accompanying drawings and implement
Example is described in further detail to the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality
With new, it is not used to limit the utility model.
A kind of adaptive injection head of the present utility model, including injection head 1, upper contiguous block 2, lower connecting block 3, limited block
4th, jumper bar 5 and bushing 6, wherein,
Limited block 4 is semi-cylindrical, and its section is in concave；
The section of upper contiguous block 2 and lower connecting block 3 is in "convex" shaped, is superimposed up and down by different size of two disks
Form, the upper surface of upper contiguous block 2 is fixedly connected with jumper bar 5, and the upper surface of lower connecting block 3 is fixedly connected with injection head 1, upper company
Connect block 2 and contact setting with the lower surface of lower connecting block 3；
Limited block 4 is arranged on the side of contiguous block 2 and lower connecting block 3, and contiguous block 2 is superscribed in the recess of limited block 4
With lower connecting block 3, limited block 4 coordinates with upper contiguous block 2 and the gap of lower connecting block 3 respectively；Limited block is at least provided with one piece, preferably
, two pieces are arranged to, one cylinder of such two pieces of formation, upper contiguous block 2 is arranged on two pieces of limited blocks with lower connecting block 3 and formed
Space in, the more firm stable that makes them be moved in space；Bushing 6 is set with outside limited block 4, it is spacing for ensureing
Block 4 is without departing from upper contiguous block 2 and lower connecting block 3.
The distance of upper surface to lower surface inside limited block 4 is equal to the height of upper contiguous block 2 and the lower disc of lower connecting block 3
With, it can so ensure that upper contiguous block 2 and lower connecting block 3 will not move up and down in limited block 4, only can plane floating.
The overall diameter of bushing 6 is less than the diameter of injection head 1, can so ensure that bushing does not interfere with injection head 1 and enters pan feeding
In cylinder.
The utility model when in use, due to upper contiguous block 2, lower connecting block 3, limited block 4 and bushing 6 be activity even
Connecing, upper contiguous block 2 and lower connecting block 3 can float with respect to plane, corresponding to be floated for injection head 1 and jumper bar 5 with respect to plane, this
Sample can make injection head 1 and the size of expects pipe be made as precise match, can so remove sealing ring from, reduce replacing number,
And simple in construction, convenient disassembly,
Preferred embodiment of the present utility model is these are only, is not used for limiting practical range of the present utility model；If
Spirit and scope of the present utility model are not departed from, the utility model are modified or equivalent substitution, all should be covered in this reality
Among new scope of the claims.
