Description

Technical Field

[0001] The utility model relates to the field of production molds, in particular to a base double-layer material belt integrated molding mechanism. Background Art

[0002] 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, 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. 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 shape of the contour line. The use of the inner cavity shape can make the blank obtain the 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 workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming; at the same time, the mold can be divided into different types according to the different objects to be processed and produced.

[0003] Terminal mold is a mold tool used to make wire connection terminals. It is usually made of high-hardness alloy steel or carbon steel. The surface is passivated and can resist high temperature, wear and corrosion. The terminal mold can be used to make the connection terminals into different shapes and sizes to meet different circuit connection needs.

[0004] When facing products with special requirements such as inconsistent terminal heights, the existing technology uses different terminals. Before entering the mold, it is necessary to fix them with welding equipment and then weld them, so that a strip is driven into the mold for molding. After molding, it is cut by cutting equipment, which leads to the need to increase equipment and manpower for welding inspection and cutting inspection during the production process. The entire production line needs more space when it is lengthened, and poor welding will have the risk of product short circuit, making it difficult to ensure production quality and low production efficiency. The purpose of this utility model is to solve the above defects and provide a base double-layer strip integrated molding mechanism. Utility Model Content
