Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present invention provides a kind of injection equipments, referring to attached drawing 1, including：Be welded 1, valve rod 2, guide rod 3, first of gun barrel is close
Seal 4, valve seat 5, the second sealing ring 6, piston 7, guide pin 8, first connecting rod 9, reset spring 10, nut 11, trigger 12, connecting rod are multiple
Position spring 13, body 14, pushing block 15 and second connecting rod 16；
The gun barrel is welded the small cylindrical section and large cylinder section that 1 docks by taper cone barrel section and respectively with cone tube shape section both ends
Composition；Gasket is installed with the place of docking of small cylindrical section in the small end of taper cone barrel section；
One end of the valve rod 2 is cone-shaped structure；
The outer circumference surface of the piston 7 is machined with strip groove；
The outer circumference surface of the valve seat 5 is machined with strip through-hole；
Integrated connection relationship is as follows：Be welded 1 large cylinder section of gun barrel is docked with valve seat 5, and to be equipped with first close for interface
Seal 4；Piston 7 is sleeved on the inner peripheral surface of valve seat 5, is equipped with four the second sealing rings of circle 6 in the contact surface of piston 7 and valve seat 5；
Guide pin 8 is fixed on valve seat 5, and be located at piston 7 strip groove in, when piston 7 is axially moved, guide pin 8 to piston 7 into
Row axial limiting；Reset spring 10 is mounted in valve seat 5,10 both ends of the reset spring end with the end face of valve seat 5 and piston 7 respectively
Face is inconsistent；Valve rod 2 be mounted on gun barrel be welded 1 and piston 7 formed cavity in, and with gun barrel be welded 1 and piston 7 it is coaxial divide
The opposite end of cloth, the cone-shaped structure of valve rod 2 is fixed on piston 7 by nut 11, and the cone-shaped structure of valve rod 2 is contradicted in rifle
Pipe is welded on 1 gasket；One end of two guide rods 3 is each attached on valve rod 2, and the other end is contradicted to be welded in 1 in gun barrel
Periphery realizes guiding role when being axially moved to valve rod 2, prevents valve rod 2 from carrying out eccentric motion；
