Specific embodiment
It is specifically described technical solution of the present invention with reference to embodiments, present invention discloses one kind convenient for discharge tensioning member
The mold of annular waste material includes mutually matched upper and lower mould similarly to the prior art in conjunction with shown in Fig. 1-Fig. 5.It is described
Upper mold includes upper die holder 1, upper padding plate 2, upper clamp plate 3.The lower die includes lower die holder 8, lower template 5, and the lower template 5 is set to
The upper mold surface side of the lower die holder 8.The edge of a knife for shaped article is provided in the lower template 5.
Unlike the prior art, the first lower bolster 6, are additionally provided between the lower template 5 and the lower die holder 8
Two lower bolsters 7.The lower die surface side of the lower die holder is additionally provided with lower bolster 11, between the lower bolster 11 and the lower die holder 8
It is provided with fixing seat 10, nitrogen gas spring 9 is provided in the fixing seat 10, the telescopic end and jigger pin of the nitrogen gas spring 9 connect
It connects.
Waste material discharging mechanism is provided with by guide pin 4 on the upper clamp plate 3, the waste material discharging mechanism includes arc-shaped
What is be arranged draws material guide rail 12, is set to the punching punching pin 121 that the side for drawing material guide rail 12 is used to make annular waste material open loop, institute
State the punching V-shaped setting of punching pin 121.Specifically, the material guide rail 12 that draws is hollow arc column, section is arc-shaped.
The distal end for drawing material guide rail 12 is connected with a punching pin 13, and the punching pin 13 includes being set to the company drawn in material guide rail
A section B is met, and for the acting section A of punching, boot segment is provided between the linkage section B and acting section A, the punching pin passes through company
Connect a section B be set to it is described draw in material guide rail, the punching punching pin 121 is set to the side of the punching pin 13.Punching when in order to be punched
Head preferably imports product, and the head of the formed punch 13 is provided with certain taper, i.e. point diameter is less than rear end diameter.
In order to further be fixed, it is described draw material guide rail 12 and punching pin 13 and pass through fixed screw 17 connect, it is described solid
Determine screw and is set to the side for drawing material guide rail and the punching pin 13.
In order to better meet discharge function of the invention, the φ 1 for drawing material guide rail 12 is less than boot segment φ 2, institute
Boot segment diameter phi 2 is stated less than the acting section A diameter phi 3, and the height H1 for drawing material guide rail and draw material section height H3 it
