Abstract

The invention discloses an upper male die of a punching die of a front frame fastener of a liquid crystal display. The upper male die of the punching die of the front frame fastener of the liquid crystal display is an upright body which has a specially-shaped cross section, and the lower end of the upright body is a diagonal plane; and the cross section of the upper male die is leftwards convex, the convex part of the cross section is circular, and all connecting parts of the cross section are of circular arc transition. Due to adoption of the mode, the production procedures are simplified, the actual production is enabled to be more convenient and rapider, and meanwhile, more manpower and material resources can be saved; and the upper male die disclosed by the invention is suitable for flow line production of products and has the advantages of saving the production cost and greatly improving the production efficiency of enterprises.

Description

Technical field [0001] The invention relates to the field of stamping dies, in particular to an upper punching die of a buckle stamping die of a front frame of a liquid crystal display. Background technique [0002] Stamping dies are used for sheet metal stamping forming and blanking separation, including punching dies, bending dies, drawing dies and turning dies. In the stamping die, the sheet metal is formed through the mold cavity, and the sheet metal is separated or cut by the punching edge of the stamping die. The most commonly used stamping die has only one station to complete a production process. In order to improve productivity, multiple stamping processes, such as blanking, deep drawing, punching, trimming, etc., can be designed on a stamping die, so that the sheet metal can complete multiple stamping processes at one station. The mold is called a composite mold. [0003] The stamping mold usually includes an upper mold, a lower mold, an upper mold fixing plate, a lowe...
