The invention discloses a pressure injection mold with a sprue spreader. That plastic from a runner uniformly flows to two sides of a mold cavity is ensured through the sprue spreader and sufficient filling of the two sides is ensured. The compression mold with the sprue spreader comprises an upper cavity capable of moving vertically and a lower cavity positioned and fixed under the upper cavity; the upper cavity and the lower cavity are assembled to form the mold cavity; a feeding cavity is positioned at the lower part of the lower cavity; the runner on the feeding cavity is communicated with the mold cavity; the sprue spreader is mounted at the lower part of the upper cavity and extends into the mold cavity; the vertical center line of the sprue spreader and the vertical center line of the runner are on the same straight line; the sprue spreader comprises a lower point end and an upper rod end; the rod end is detachably connected onto a seat body; and the seat body is fixed at the bottom of the upper cavity.
