The specific embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technical scheme of the present invention in detail.Fig. 1 is quickly opening and closing fixture matched moulds state general assembly drawing of the present invention, and Fig. 4 is die opening state general assembly drawing of the present invention.
As shown in figs. 1 and 4, the present invention includes and be fixed on patrix matchboard 1 and counterdie matchboard 2 clamp body above, described clamp body is divided into two parts: be respectively clamp body and lower clamp body, upper clamp body comprises the leading cover 12 of dish spring group 5, dust cover 6, spinner pin 7, round nut 8, upper trim ring 9, main stroke spring 10, spring chain female connector 11 and spinner pin; Lower clamp body comprises limited block 16 and spinner plate 19.
The through-shaft that spinner pin 7 is upper clamp body, the bottom of the leading cover 12 of spinner pin has for being fixed in patrix matchboard 1 flange face above, the central through hole of the leading cover 12 of described flange face and spinner pin is ladder, the endoporus of described ladder respectively with the multidiameter matched in clearance of spinner pin 7, when its ladder endoporus anchor ring and spinner bearing pin shoulder grafting touch, this is the activity upper limit of spinner pin, dish spring group 5 is enclosed within on the leading cover 12 of spinner pin, and the lower end of dish spring group 5 is pressed on the ladder anchor ring of the leading cover 12 of spinner pin.
Spring chain female connector 11 is the cylinder of two ends counterbore, axis through-hole, and the anchor ring of the lower surface of spring chain female connector 11 and lower end counterbore is pressed in respectively dish spring group 5 and dominates on the end face of cover 12 with spinner pin.
Bottom one side of upper trim ring 9 and the upper end of dust cover 6 weld together, and described upper trim ring 9 is pressed on the shaft shoulder and main stroke spring 10 of spinner pin 7, under matched moulds state, between the end face of described upper trim ring 9 and round nut 8, has certain interval.
