Description
Technical field
The present invention relates to field of semiconductor manufacture, in particular to a kind of injection head of fast assembling-disassembling.
Background technique
Injection head and mold generate friction, need to replace injection head after long-time service, in the prior art, generally adopt
It is threadedly engaged, is likely to occur for a long time without dismounting stuck equal existing with oil cylinder screw with more barrel encapsulating mould injection heads
As, it is subsequent to be not easy to replace injection head, and heating for a long time is easy more jin of injection head in a mold and barrel generates
Deviation causes the abrasion of barrel.
Summary of the invention
For the above defect of the existing technology, it is a primary object of the present invention to overcome the deficiencies in the prior art it
Place, discloses a kind of injection head of fast assembling-disassembling, including injection head, housing, upper locking piece, lower closing piece, bottom plate and circle bayonet lock,
In,
Bayonet lock mounting groove is provided on the lower closing piece, the round bayonet lock is arranged in described in the lower closing piece by spring
In bayonet lock mounting groove, to described one power upward always of round bayonet lock；
The upper locking piece structure in the shape of a " convex ", the upper surface of the upper locking piece are fixedly connected with the upper injection head, under
Surface is provided with the latch recess of the justified bayonet lock on being caught in；
The housing upper surface is provided with the opening to match with upper institute's upper locking piece, and the upper locking piece can be made smoothly to lead to
It crosses；
The lower closing piece is arranged on the bottom plate, and the coat suit connects outside the lower closing piece and with the bottom plate
It connects.
Further, at least one piece of limited block is provided on the lower closing piece.
Further, the limited block is provided with two pieces.
Further, two pieces of limited blocks are arranged by point of rotation rotational symmetry of the rotation center of the injection head.
Further, removable by screw between the lower closing piece and the bottom plate, between the housing and the bottom plate
Unload connection.
Further, the cavity and the upper locking piece clearance fit that the lower closing piece and the housing are formed.
It is that the present invention obtains the utility model has the advantages that
The present invention, which rotates injection head by bayonet lock, to fix, and easy to operate, it is convenient to dismantle, and use for a long time will not go out
Existing stuck phenomenon, while limited block is set, injection head rotation can be prevented excessive；In addition, upper locking piece and lower closing piece and housing
The cavity clearance of formation cooperates, and makes to inject head plane floating, appropriate adjusting can be made according to barrel.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
As shown in Figs 1-4, the injection head of a kind of fast assembling-disassembling of the invention, including injection head 1, housing 2, upper locking piece 3, under
Closing piece 4, bottom plate 5 and circle bayonet lock 6, wherein
Bayonet lock mounting groove 41 is provided on lower closing piece 4, the bayonet lock mounting groove of lower closing piece 4 is arranged in by spring for circle bayonet lock 6
In 41, give circle 6 one power upward always of bayonet lock, make no external force push in the case where always some be higher than lower closing piece
4 upper surface；
The structure in the shape of a " convex " of upper locking piece 3, the upper surface of upper locking piece 3 are fixedly connected with injection head 1, and lower surface setting is useful
In the latch recess 31 for being caught in round bayonet lock 6；
2 upper surface of housing is provided with the opening to match with upper locking piece 3, and upper locking piece 3 can be made to pass through；
Lower closing piece 4 is arranged on bottom plate 5, and housing 2 is sleeved on outside lower closing piece 4 and connect with bottom plate 5.
When injection head 1 of the invention is installed, it is only necessary to upper locking piece 3 is inserted into housing 2, and circle bayonet lock 6 is pressed, led to
Crossing rotary injection head 1 drives upper locking piece 3 to rotate, until circle bayonet lock 6 is caught in latch recess 31；In disassembly, it is only necessary to will infuse
It penetrates first 1 to reversely rotate, upper locking piece 3 is removed out of housing 2 opening.
Injection head 1 rotates excessively in order to prevent, at least provided with one piece of limited block 7 on lower closing piece 2, it is preferred that with
The rotation center of injection head 1 is that two pieces of limited blocks 7 are arranged in point of rotation rotational symmetry.
For save the cost, it is detachably connected between lower closing piece 4 and bottom plate 5, between housing 2 and bottom plate 5 by screw, this
Sample only replacement can damage component, without all replacements when there is parts damages.
The cavity and 3 clearance fit of upper locking piece that lower closing piece 4 is formed with housing 2, can make injection head 1 small in cavity in this way
Range activity floats for plane, can make adjustment appropriate according to barrel in this way with injection head 1.
The present invention, which rotates injection head 1 by bayonet lock, to fix, and easy to operate, it is convenient to dismantle, and use for a long time will not
There is stuck phenomenon, while limited block is set, can prevent injection head 1 from rotating excessively；In addition, upper locking piece 3 and lower closing piece 4 with
The cavity clearance cooperation that housing 2 is formed makes to inject head plane floating, appropriate adjusting can be made according to barrel.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
