Abstract

The invention relates to the technical field of hardware, in particular to a method for cleaning waste through die punching, which comprises a die main body, an integrally formed waste discharge hole is formed in the center of the surface of the die main body, a rubber ring is arranged at the edge of the waste discharge hole, rubber is reserved on the surface of the rubber ring, and a bottom film is arranged on the surface of the die main body. The use method comprises the following steps: 1, comprehensively rubberizing the surface of the die main body; 2, remaining rubber in the middle of the rubber ring at the waste discharge hole; 3, pasting a rubber ring on the waste discharge hole to the bottom film; 4, directly sticking release paper on the surface of the die main body; and 5, aligning a drilling tool to the release paper for punching, arranging punching rings on the two sides of the waste discharge hole, and an integrally formed positioning ring is arranged on the surface of the punching ring. The method has the beneficial effects that the punching ring is arranged, so that the whole die can be conveniently fixed by a punching part through the punching ring, and the phenomenon that the die deviates during punching is prevented.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to a method for opening holes in molds and cleaning waste. Background technique [0002] Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank in...
