Abstract
The invention relates to an asynchronous material returning and ejection mechanism of a main die. The mechanism comprises a die sleeve, wherein a floating alloy die is arranged at the front end in the die sleeve; a rear pad, which is fixed with the die sleeve by a scroll, is arranged at the rear end in the die sleeve; a spring pad block is arranged on the rear pad in the die sleeve; a spring contacting the floating alloy die is arranged in the spring pad block; a slidable material returning pipe, in which a slidable tensile punching rod is arranged, is arranged in the middle of the floating alloy die; a material returning needle, one end of which props against the material returning pipe, is arranged in the rear pad; an annular bulge is arranged in the middle of the tensile punching rod, which penetrates through the rear pad; a punching rod slot for placing the annular bulge is arranged in the rear pad; and one end of the tensile punching rod is the head part, while the other end of the tensile punching rod is provided with a stop nut. Due to material pushing by the tensile punching rod and the material returning pipe together, the asynchronous material returning and ejection mechanism disclosed by the invention is capable of avoiding bending or breaking caused by boost pressure of the material returning pipe by instantaneous double-strength when the product ejects and tail hole tensile punching rods return synchronously caused by fixed tensile punching rods, and ensuring consistency of the parts center and the tensile punching rods center.

Further concrete, be provided with middle cushion block between described spring cushion block and the rear pad.
For material returned pipe can better be contacted with material returned pin, better finish the task of ejecting, described material returned pipe bottom is provided with material returned pipe adjusting pad and contacts with material returned pin.
For can be in that to release part stress even, further concrete, at least three on described material returned pin and evenly distributing.
In order conveniently to adjust the punching rod that stretches, further concrete, be provided with to stretch and rush excellent adjusting pad near rushing excellent groove on the described annular projection.
The part that differs in order conveniently to process bar minister degree, further concrete, described rear rebasing section is provided with limited impression and cooperates with stop nut.
For can be after the pusher material returned pipe and stretching rush the club head front end and guarantee flushly, further concrete, the length of described material returned pin deducts the bar minister degree that the length of the punching rod that stretches from annular projection to the punching rod bottom that stretches equals to stretch and rushes club head.
The invention has the beneficial effects as follows: adopted after the said structure, punching rod and the asynchronous pusher of material returned pipe stretch, having avoided pull and stretch to rush product that excellent fixed method for designing causes ejects and rushes rod with the uropore pull and stretch and withdraw from simultaneously, the pressure that instantaneous dual strength increases material returned pin causes regular bending or fractures, and it is consistent to guarantee that excellent center is rushed in Central of the parts and stretching.
