The utility model provides a lower die inner sucker rod guiding device comprising a copper guide rail (1) and a slide block (2). The slide block (2) is in a sliding connection with the guide rail (1). The guide rail (1) is provided with a lubrication hole (3) for self-lubricating, and a graphite (4) is positioned inside the lubrication hole (3). Compared with the prior art, the guide rail is made by copper and provided with lubrication hole for self-lubricating, the graphite is mounted inside the lubrication hole, the copper is provided very tough and wear resistant properties and also a certain self-lubricating effect, and the graphite has the lubricating effect. Thus a stagnation is not prone to occur in the sliding connection between the guide rail and the slide block and the wearing and tearing of the guide rail or the slide block is not prone to occur, thereby ensuring that the inner sucker rod can function smoothly and further improving production yield and production efficiency of the mold and prolongi
