Mold mechanism manufactured based on modified engineering plastic tensile property test sample strip

The utility model relates to the technical field of engineering plastic modification, in particular to a mold mechanism for manufacturing a tensile property test sample strip based on modified engineering plastic. The mold mechanism manufactured based on the modified engineering plastic tensile property test sample strip comprises a mold body, a mold cavity is formed in the mold body, a protruding combination part and a clamping part which are used for fixing the mold body are arranged on the mold body, a runner opening communicated with the mold cavity is formed in the protruding combination part, and the clamping part is arranged on the mold body. A first convex block is arranged at the side part of the convex combination part, so that the tight combination of the mold and the material conveying device can be ensured, the loss of materials in the sample preparation process is prevented, and the materials can be fully utilized to avoid the waste of the materials; and the clamping part is arranged, so that th
