The AC plug mold can be intuitively understood from three aspects!

The AC plug mold can be intuitively understood from three aspects!

        1. Concept

　　The mold makes the blank into a product with a specific shape and size under the action of external force. Widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts limitation, 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 use of a contour shape with a cutting edge can separate the blanks according to the contour shape (punching). Applying the shape of the inner cavity enables the blank to obtain a corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold (or convex mold and concave mold) two parts, the two can be divided and combined. When separated, the parts are taken out, and when closed, the blank is injected into the mold cavity to form. The mold is a delicate thing, with a complex shape, which bears the expansion force of the blank. It has high requirements on structural strength, stiffness, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important signs of machinery manufacturing level.

2. Variety

　　 There are many types of molds, which can be divided into: ① metal processing molds according to the processing objects and processing techniques. ②Process non-metallic and powder metallurgy molds. Including plastic molds (such as injection molds, compression molds and extrusion molds), rubber molds and powder metallurgy molds. According to the structural characteristics, the die can be divided into flat punching die and cavity die with space. The mold is generally a single piece, produced in small batches.

　　 3. Composition

　　In addition to the mold itself, it also needs a mold base, a mold frame, a guide device and a part ejection device, etc. These parts are generally made into a universal type. The needs of mold companies are bigger and more refined. It is necessary to determine product positioning and market positioning based on market demand, technology, capital, equipment and other conditions. These practices are especially worthy of learning and learning for small mold companies to concentrate on gradually forming their own technological advantages and products. Advantage. Therefore, my country's mold companies must actively strive to learn from the experience of these advanced foreign companies in order to better their future development.
