[0040] Examples:
[0041] An extrusion molding die for bar material with holes of the present invention, such as Figure 1-16 , Including the core rod seat 1, the core rod 2 and the rod forming mold 3, the core rod seat 1 is a disc core rod seat, and the outermost part away from the center of the circle is provided with a protruding fixing part 11, the core rod seat 1 passes The fixing portion 11 is detachably fixed on the top of the rod forming mold 3 and completely covers the rod forming mold 3, the core rod 2 passes through and is assembled in the axial center of the core rod seat 1, and the core rod 2 passes through the rod The molding die 3 is suspended and fixed in the inside of the rod molding die 3 through the core rod seat 1. There is no gap between the core rod seat and the mold body, which avoids the problems that the core rod seat cannot be taken out and the mold cannot be cleaned due to material accumulation in the gap, thereby avoiding product contamination.
