Novel high-stability test bar mold

The utility model discloses a novel high-stability test bar mold which comprises two bodies hinged to each other, mold cavities are formed in the opposite sides of the two bodies respectively, heat dissipation grooves are formed in the top faces of the bodies, a plurality of heat conduction blocks are fixed to the side walls of the heat dissipation grooves, heat dissipation blocks are fixed to the heat dissipation grooves, and a plurality of heat dissipation holes are formed in the heat dissipation blocks. One side of each heat dissipation hole is communicated with a heat conduction channel and penetrates through the side wall of the heat dissipation block to be fixedly connected with a heat conduction pipe, a cavity is formed in the heat conduction block, the heat conduction pipe penetrates through the heat conduction block and is communicated with the cavity, a cooling pipeline is fixed between the heat dissipation block and the heat dissipation groove, one side of the cooling pipeline is fixedly connected
