The present invention provides an extrusion die structure, and the problem to be solved is a sawtooth structure existing on the end face of the discharge port of the conventional extrusion die, which is prone to deformation and breakage during long-term operation, resulting in a situation The problem of the relevant extension is improved； the extrusion die structure mainly comprises: the tapered pipe system defines the first pipe section and the second pipe section according to the position, the outer end face of the second pipe section is formed with the inlet opening； the tapered discharge hole is formed And an outer end surface of the first pipe section； and at least three groove depressions are formed on the outer surface of the first pipe section, and at least three grooves are configured to change the horizontal cross section of the tapered discharge hole； wherein the width of the tapered pipe body is The taper discharge hole is gradually expanded toward the feed port, and a funnel passage connecting the inlet port and the tapered discharge hole is formed inside the tapered pipe body.本創作係提供一種擠製模具結構，其所欲解決之問題點，係針對習知擠製模具之出料口端面所存在之鋸齒狀結構，長時間運作時容易有變形、斷裂等狀況，造成相關延伸性之問題加以改良突破；所述擠製模具結構主要包括：錐狀管體係依位置定義第一管段與第二管段，第二管段外端面形成有入料口；錐形出料孔形成於第一管段外端面；以及至少三個溝槽凹陷形成於第一管段外表面，至少三個溝槽以供改變錐形出料孔水平截面的結構形狀；其中，錐狀管體的寬度係自錐形出料孔處往入料口的方向漸擴，且錐狀管體內部形成有連通入料口與錐形出料孔之容料通道。
