Pressure die with good sealing effect

The pressure die with the good sealing effect comprises a bottom plate, a fixed die body is fixedly installed on the right side of the top of the bottom plate, a movable die body is movably installedon the left side of the top of the bottom plate, a sealing disc is fixedly installed at the left end of the fixed die body, and a sealing sleeve is fixedly installed at the right end of the movable die body. According to the utility model, the transmission mechanism drives the concave fixing sleeve to move rightwards through the connecting mechanism; the concave fixing sleeve drives the pressing sleeve to press the sealing sleeve through the arc-shaped plate and the pull plate; the sealing sleeve is tightly matched with the sealing disc; therefore, the pressure die can be effectively pressed;the pressure die has the advantages of being simple in structure and good in sealing performance, the problem that the sealing effect of the pressure die is reduced to a certain degree due to the factthat an existing pressure
