Precise small hole stamping mold of filtering plate

Abstract

The invention discloses a precise small hole stamping mold of a filtering plate. The precise small hole stamping mold comprises an upper mold plate, a lower mold plate, guide sleeves, outer guide columns, a cushion plate arranged on the bottom face of the upper mold plate, a punch fixing plate arranged below the cushion plate, a stripper plate connected to the portion below the punch fixing plate through inner guide columns, a punch arranged on the punch fixing plate, a female mold arranged on the lower mold plate and a rubber arranged between the punch fixing plate and the female mold, wherein the guide sleeves and the outer guide columns are arranged between the upper mold plate and the lower mold plate. A frame-shaped positioning frame is arranged on the periphery of the stripper plate. The frame-shaped positioning frame movably penetrates and is installed on the punch fixing plate on the rear side through the guide columns. A punch guiding barrel is movably arranged on the part, on the periphery of the punch, of the stripper plate. According to the precise small hole stamping mold of the filtering plate, positioning is carried out in advance through the frame-shaped positioning frame, material pressing is carried out on the periphery of the filtering plate, and then the punch carries out rapid impact along the punch guiding barrel. The precise small hole stamping mold is precise in positioning and high in punching quality.
