An injection mold with rapid cooling

Technical Field

The utility model belongs to the technical field of injection molds, and in particular relates to an injection mold with rapid cooling.

Background Art

Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools 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 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 pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch) according to the contour shape. The use of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally consists of two parts: a movable mold and a fixed mold (or a punch and a die), which can be separated or combined. When separated, the part is taken out, and when closed, 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 for 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.
