Seam chamber 21 and nib die cavity 22 etc. are arranged on counterdie 2.Seam chamber 21 be metal collection that tap hole 12 is flowed out together again seam to get up to form with core rod 13 be the integral blank at center because metal is constantly assembled, static pressure constantly increases, until extruding nib.Alignment pin through hole 23 and screwing through hole 24 are arranged in the counterdie 2.As shown in Figure 3.

Alignment pin 3 is used for carrying out the assembling and positioning of patrix 1 and counterdie 2, is that upper and lower mould 1 and 2 is bound up securely and connect screw 4, makes the plane divergent die form an integral body, is convenient to operation, and can increases intensity.

The width of shunting bridge 11 is relevant with the flow of mould strength and metal, and the height of shunting bridge 11 directly influences die life, extruding force, and weldquality.The cross sectional shape of shunting bridge 11 directly influences flowing and seam of metal, and the gradient of shunting bridge 11 is also referred to as the seam angle, and the quality of its big or small butt welded seam quality has a direct impact.The design of therefore shunting bridge is directly connected to the quality of welding seam of articles.

Tap hole in the conventional plane divergent die is vertical seam chamber, and the shunting bridge all be adopt linear, as shown in Figure 4.Its cross section is shunted bridge based on this linear pattern, during work as shown in Figure 5, two strands of metal flows weld seam of seam herein also are straight lines, because metal has only rectilinear motion to nib by the seam chamber, thus the seam line C of straight line type on product, will be formed, as shown in Figure 6.Its mechanical property is bad.The product that has will carry out deep processing, split and can not use from straight bead with regard to being easy to, or the welding quality of commissure is bad, causes product surface that tangible weld seam vestige is arranged, and influences the surface of goods and uses.
