Sliding seat and machining process thereof

The invention discloses a sliding seat which comprises a main body, wherein the front surface of the main body is provided with a clamping and embedding structure connected with a telescopic mechanism and a plurality of through mold closing piece mounting holes; a positioning bulge matched with the mold closing piece is arranged on the back surface of the main body; the insertion core body is arranged on the upper surface of the main body; an inclined chamfer surface is arranged at the junction of the front surface and the outer side surface of the ferrule body; a through insertion core hole and a plurality of fixing holes are formed in the chamfered surface; the limiting body is arranged on the lower surface of the body, and the surface, in the same direction with the front face of the sliding body, of the limiting body is inclined. The area of the cross section of the limiting body is decreased along with increasing of the distance from the lower surface of the sliding body. The processing technology compri
