The invention relates to an automobile spare part production mold, in particular to an automobile connection rod injection mold. The automobile connection rod injection mold comprises a first mold and a second mold, wherein the first mold and the second mold are the same in structure, the first mold and the second mold both comprise fixed molds and movable molds, pouring gates are formed in the movable molds, the fixed molds and the movable molds are connected through press rods, and the press rods are connected with air cylinders; the fixed mold of the first mold is connected with the fixed mold of the second mold through a telescopic rod. By means of the design of the telescopic rod, connection rods of different connection lengths can be processed; the connection rods with different length requirements can be processed only by adjusting the length of the telescopic rod; symmetrical and asymmetrical connection rods also can be produced; thus, the production adaptability is improved, and multi-type molds are avoided being matched.
