Multi-column trapezoidal fixed valve mold

Abstract

The invention relates to a multi-column trapezoidal fixed valve mold. The mold comprises an upper mold connected with a puncher pin and a lower mold detachably arranged on a working platform of a punching machine. The upper mold and the lower mold are oppositely arranged in the vertical direction. The lower mold comprises a lower mold supporting plate, a press block connecting block, a lower moldpress block, a bottom mold, moving guide shafts and springs. The lower mold press block comprises multiple lower mold protruding punching portions, multiple connecting bolts and multiple nuts. The upper mold comprises a puncher pin connecting portion, a vertical connecting portion, an upper mold press block and multiple press-fitting grooves. The mold is scientific and reasonable in design, simplein structure and convenient to operate; during use, multiple valve holes can be punched at the same time at a time; different use requirements are met; meanwhile, the work efficiency is improved; andquality uniformity of manufactured products is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mold equipment, in particular to a multi-row trapezoidal solid valve mold. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is to use a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation. [0003] However, although there are some trapezoidal solid valve molds at present, they still cannot meet the existing use requirements. At present, when the existing trapezoidal solid valve molds are in use, generally only one operation can punch out the valve hole of a trapezoidal solid valve. If the trapezoidal solid valve has multiple valve holes, multiple stamping operations are required. The existing trapezoidal solid valve mold not o...

[0003] However, although there are some trapezoidal solid valve molds at present, they still cannot meet the existing use requirements. At present, when the existing trapezoidal solid valve molds are in use, generally only one operation can punch out the valve hole of a trapezoidal solid valve. If the trapezoidal solid valve has multiple valve holes, multiple stamping operations are required. The existing trapezoidal solid valve mold not only has low working efficiency, but also the quality of the products produced is not uniform. Therefore, a new trapezoidal solid valve mold is urgently needed
