Split type sealing ring forming die facilitating demolding

Abstract

The utility model discloses a split type sealing ring forming die convenient to demould relates to mould technical field, including upper die, the lower portion of upper die is provided with lower die, the bottom of lower die is provided with limit box, and the surface of lower die is provided with connecting groove, the inside slide coupling of lower die has the ejection rod, and the bottom of ejection rod is provided with the demoulding mechanism for the sealing ring ejection, and the ejector block fixed connection in the top of ejection rod. The split type sealing ring forming die convenient to demould, through the separation between upper die and lower die, reset spring pushes the ejection rod and fixed plate of top through the elastic force of itself and resets, simultaneously, the ejector block also resets synchronously and pushes out the sealing ring in the inside of die groove, and the inside of every die groove is provided with two ejector blocks, therefore, the sealing ring in the inside of die groove can be pushed out from left and right sides, thereby realizes the demoulding processing of sealing ring.
