die refers to the tool that turns the blank into a part with a specific shape and size under the action of external force. it is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and engineering plastics and rubber , ceramics and other products in the compression molding or injection molding processing. the mold has a specific contour or inner cavity shape, and the contour shape with a cutting edge can be used to separate the blank according to the contour shape (punching).
when some molds, such as plastic molds, are in operation, due to the presence of chlorine and fluorine in the plastic, strong corrosive gases such as hci and hf will be resolved after heating, which will erode the surface of the mold cavity, increase its surface roughness, and increase wear failure.
mold plays an extremely important role in modern industry, and its quality directly determines the quality of the product. improving the service life and accuracy of molds and shortening the manufacturing cycle of molds are technical problems that many companies urgently need to solve. however, in the process of mold use, there are often problems such as collapse, deformation, wear, and even breakage that need to be repaired.
