The present invention discloses an extrusion mold with an improved structure. The extrusion mold comprises an upper mold and a lower mold, wherein the upper mold and the lower mold are fixedly connected, the upper end of the upper mold is provided with a diversion plate, bridging positions are arranged inside the diversion plate, the edges of the bridging positions are provided with chamfer structures, shunt holes are formed between the bridging positions, a core head is arranged below the diversion plate of the upper mold, the lower mold is sequentially provided with a soldering chamber, a molding hole and a material discharge hole from top to bottom, the soldering chamber, the molding hole and the material discharge hole are communicated, the soldering chamber is communicated with the shunt hole of the upper mold, the core head of the upper mold is inserted into the molding hole of the lower mold, the soldering chamber of the lower mold comprises at least two stages of sub-soldering chambers, and various stages of the sub-soldering chambers present the stepped alignment state in a gradual diameter reduction manner. According to the present invention, the bridging position edge of the upper mold is designed into the chamber structure so as to provide a diversion effect for the material entering the shunt hole, achieve rapid material shunt and ensure the sufficiency of the material in the molding hole; and after the shunted material enters the soldering chamber and is subjected to multi-stage gradual molding, the whole strength is high, the molded product has a smooth surface, the molding effect is good, and the mold is not easily damaged.
