Road carries out transverse shifting, and staff can carry out large range of transverse shifting to intermediate shooting rifle 12 to adapt to molding die
The position in intermediate feed hole；After unscrewing locking device 124, intermediate transit elbow 123 can rely on the company of the first heel 1231
Connector 123a and the conical head 1211 of intermediate 12 discharge end of shooting rifle are rotated, and the intermediate specifically alignment molding of material sputtering nozzle 122 is made
The intermediate feed hole of mold after alignment, can screw locking device 124, keep positioning convex strip 123a11 and strip groove 12121 corresponding
It is fastened togather, it is ensured that intermediate transit elbow 123 is not in the rotation of inhuman wish；After locking device 124 screws, taper
First 1211 surface and conical inner surface 123a2 mutual cooperation clamp elastic packing bed course 12112 and carry out on this contact surface
Sealing, and outer ring burr 12111 and annular burr 123a21 can clamp elastic packing bed course 12112 in two sides, make
Deformation occurs on elastic packing bed course 12112 surface mutually insertion outer ring burr 12111 and annular burr 123a21 is significant to increase
Big area in sealing contact, sealing effect are stronger.
Preferably, the gap between the corresponding positioning convex strip 123a11 of locking device 124 and strip groove 12121 be formed with
The through-hole 1243 of external world's connection.During gradually screwing locking device 124, locking device 124, intermediate shooting gun main body
Air between 121 and intermediate transit elbow 123 in gap can be discharged from through-hole 1243, be convenient for locking operation.
In order to ensure the validity that through-hole 1243 works plays, it is preferable that the diameter of through-hole 1243 is 1-2mm.
Preferably, the cross section of outer ring burr 12111 and annular burr 123a21 are gradually to be become by tip to root
Wide triangle, and the tip of the cross section of outer ring burr 12111 and annular burr 123a21 is smooth arc.This structure
It can guarantee the depth of outer ring burr 12111 and annular burr 123a21 insertion 12112 surface of elastic packing bed course and close
Property, and the tip of smooth arc will not cause to damage to elastic packing bed course 12112.
Preferably, the outer surface of connector 123a is in cone, compress the inner surface corresponding section of step 1241 with connect
The outer surface of head 123a matches.While this structure can be such that locking device 124 gradually locks, using with conical inner surface
The step 1241 that compresses matched with the connector 123a with conical external surface and generate automatic alignment result, and then make to connect
Elastic packing bed course 12112 is compressed to the conical inner surface 123a2 even of head 123a, will not especially make elastic sealing gasket
Layer 12112 generates fold, it is ensured that sealing effect.
Preferably, the angle of the lateral surface of connector 123a and connector 123a axis is greater than medial surface and connector 123a
The inclination angle of the angle of axis, i.e. connector 123a lateral surface is bigger, is compressing step 1241 and connector 123a lateral surface phase
In the case where matching, this structure, which can make to compress step 1241, generates stronger pressure in the axial direction to connector 123a, enhances
Compress locking effect.
Preferably, the outer surface of connector 123a is formed with the antifriction bulge loop 123a3 concentric with connector 123a axis,
The cross section of antifriction bulge loop 123a3 is the triangle gradually to be broadened by tip to root, and antifriction bulge loop 123a3's is transversal
The tip in face is smooth arc.This structure can make the outer surface of connector 123a by antifriction bulge loop 123a3 and compress step
1241 are in contact, and can effectively reduce contact area, so be substantially reduced connector 123a outer surface and compress step 1241 it
Between frictional force, locking device 124 lock during, greatly reduce locking resistance, easily facilitate locking.Specific structure can
For locking device 124 is equipped with locking positioning device (not shown).
Preferably, the inner surface for compressing step 1241 is formed with the antifriction raised line to intersect with antifriction bulge loop 123a3
12411.This structure can make the inner surface for compressing step 1241 connect by antifriction raised line 12411 with antifriction bulge loop 123a3
Touching, can be further reduced contact area, further decrease connector 123a and compress the frictional force between step 1241.
Preferably, the cross section of antifriction raised line 12411 is the triangle gradually to be broadened by tip to root, and antifriction
The tip of the cross section of raised line 12411 is smooth arc.This structure can make antifriction raised line 12411 and antifriction bulge loop 123a3
Flexible contact significantly reduces abrasion, guarantees the persistence that mechanism uses.
Preferably, antifriction raised line 12411 and antifriction bulge loop 123a3 are perpendicular.This structure can reduce single antifriction
The contact area of raised line 12411 and antifriction bulge loop 123a3, and then it is further reduced all antifriction raised lines 12411 and antifriction
Wipe the contact area of bulge loop 123a3.
Product form of the invention is not limited to this case diagram and embodiment, anyone carries out the appropriate of similar thinking to it
Changes or modifications all should be regarded as not departing from patent category of the invention.
