The invention discloses an injection mold convenient to fix. The injection mold comprises a fixing bracket, a hydraulic machine oil pump is fixedly arranged at the upper end of the fixing bracket, andthe hydraulic machine oil pump penetrates through the surfaces of the two sides of the fixing bracket; and the hydraulic machine oil pump is fixedly arranged on the fixing bracket through bolts, a hydraulic rod is fixedly arranged on one side of the oil hydraulic machine oil pump, concave mold material pushing rods are fixedly arranged at the two ends of the hydraulic rod, and the concave mold material pushing rods are fixedly arranged on the outer surfaces of the two ends of the hydraulic rod through the bolts. The rechange of a fixing structure of the injection mold enables the injection mold to be better fixed and installed when the injection mold is in use, the mold can be quickly adjusted according to requirements when a manufacturer produces products, so that the production efficiency is greatly improved; an ejecting block is additionally arranged at a corner of the mold, so that when the mold discharges, the condition that the product is smashed from ejecting by the ejecting block in a mold discharging process due to insufficient stress at the corner of the mold can be prevented, so that yield is improved to a certain extent.
