A link type high speed press(100) includes a link driving unit and a balance weight unit. The link driving unit includes a housing(11) fixed at a side plate(331) arranged at a frame, a main gear(12) arranged outside the housing, a link arm(13) equipped with a spline(133) and joined to an inner surface of the housing, links(14,15) joined to link fixing pins(131,132) having one sides connected to link pins and the other sides mounted on the link arm arranged inside the main gear, a driving shaft(16) having one side equipped with a spline(162) and joined to the spline of the link arm and the other side joined to side plates(332,333), and a plunger housing(18) having a lower end equipped with a packing cover(181). The balance weight unit includes an eccentric cover(21) arranged at an end of the driving shaft, a balance weight(22) joined to the eccentric cover such that the balance weight is rotatable, a guide bar(23) screwed into nuts(232) of an upper plate(31) and a lower plate(32) of the frame and secured into holes of the balance weight, a balance rod(24) having one end joined to the balance tightening pin(221) and the other end joined to the eccentric cover, and an encoder(25) facing an encoder shaft(26) tightened at the eccentric cover through an encoder bracket.
