Detailed description of the invention
Being described in further detail the utility model below in conjunction with the drawings and specific embodiments, is not that practical range of the present utility model is limited to this.
As shown in Figure 1, the general material-saving type ejector of the present embodiment.General material-saving type ejector, it is characterized in that: comprise the telescopic cylinder 1 be arranged at below punch press, the expansion link upper end of described telescopic cylinder 1 is connected with strut 2, described strut 2 passes and is slidably connected with described die shoe 3 in the middle part of die shoe 3, the upper end of described strut 2 is provided with gripper shoe 4, described gripper shoe 4 is arranged at the mold cavity bottoms of counterdie 5, described gripper shoe 4 is threaded with described strut 2, the utility model scientific structure, it drives strut 2 to move upward by the telescopic cylinder 1 be arranged at below punch press, thus drive gripper shoe 4 jack-up workpiece, gripper shoe 4 is large with absorption surface area, can jack-up workpiece reposefully, and the bottom margin of counterdie 5 die cavity can be avoided to crack under the extruding repeatedly of workpiece, this ejector can be common to multiple kinds of molds, mould is made not need specialized designs ejector, provide cost savings.
Further, the bottom that described gripper shoe 4 contacts with described counterdie 5 is provided with rounded corners, avoids the damage of edges of gripper shoe 4, improves the mold use life-span.
Further, also comprise the control valve controlling described telescopic cylinder 1, the travel switch detecting patrix stroke, described travel switch is electrically connected with described control valve, by detecting the motion of the formation control telescopic cylinder 1 of patrix, thus by workpiece jack-up.The bottom of die shoe 3 is provided with groove 31, is convenient to strut 2 and stretches into.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
