Description

Technical Field

[0001] The invention relates to the technical field of mold damage detection, and in particular to a mold damage detection device. Background Art

[0002] In the mold industry, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". It is a tool that makes the blank become a part of a specific shape and size under the action of external force. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The contour shape with a cutting edge can make the blank separate (punch out) according to the contour shape. The shape of the inner cavity can be used to make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or a punch and a die), which can be separated or combined. When separated, the workpiece is taken out, and when combined, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It bears the expansion force of the blank and has high requirements on structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing. At present, the mold needs to be tested for damage inside and outside the mold during production and use.
