Specific embodiment
With reference to the accompanying drawing, the technical solution of the utility model is further described by specific embodiment.
As shown, a kind of variable cross-section deep hole part molding die, including punch-pin 3, cavity plate 6, die holder 9, ejector 10, floating
It branching block 5 and covers in the punch case 2 outside punch-pin 3 and covers the die case 7 outside cavity plate 6, the cavity plate 6 and die case 7 are arranged
At the top of the die holder 9, and the cavity plate 6 is embedded and installs ejector 10 on 9 top of die holder, the die hole and die holder 9 of cavity plate 6
Hole communicate, the ejector 10 is mounted on 9 bottom of die holder, and the mandril 8 of ejector 10 is directed at the die hole of cavity plate 6, so as to will be at
Product ejection device after type；3 top of punch-pin is in disk form, can be stuck in the mounting hole of punch case 2, under punch-pin 3
It holds to the die hole of cavity plate 6 and stretches out, be additionally provided with the floating flow-distribution block 5 between punch-pin 3 and cavity plate 6, in floating flow-distribution block 5
Heart hole 501 is opposite with the die hole of cavity plate 6, and the punch-pin 3 is allowed to pass through the die hole that centre bore 501 is inserted into cavity plate 6, to squeeze
Product moulding therein is evenly equipped with multiple blind holes 502 around centre bore 501 on floating flow-distribution block 5, and is arranged in blind hole 502
Spring 4,4 top of spring withstand on the lower surface of punch case 2, preferably, spring 4 uses nitrogen gas spring, it is further, described floating
