Specific embodiment
With reference to the accompanying drawings and detailed description explanation is described in more detail to the present invention.
Referring to Fig. 1, a kind of composite cathode of enclosed integrated member runner, including before drift 1, reaming dististyle 2, molded body 3
With tail guide pin bushing, front drift 1, molded body 3 and tail guide pin bushing 7 are internally provided with the passage being sequentially communicated.
Front drift 1 is coated with the copper-tungsten pipe of epoxy resins insulation for outer wall, and polishing circle is left in its front end.
Molded body 3 is made up of pyrite, and its outline is handgun shape, except the curved surface of the end of its gun barrel, small of the butt
Outside the frustum of section work surface and gun stock afterbody, remaining non-processing face coats epoxy resins insulation, and its gun barrel is together with being welded in its end
The brass material in portion is made reaming dististyle 2 and is designed rectangularity, the work of gun stock by the throat shape of enclosed integrated member runner
The aerofluxuss side curve form foundation of runner is pressed in faceMethod designs.
There is screwed hole at reaming dististyle 2 center, and front drift 1 is provided with screw thread and puts in molded body 3 in order to screw in reaming piece 2, its
