A decompression and dust-proof mold for metal rod processing

Abstract

The invention discloses a pressure reduction and dust prevention mold for metal rod machining. The pressure reduction and dust prevention mold comprises a workbench and a movable square plate, whereina bottom plate is fixedly arranged on the upper surface of the workbench, positioning columns are arranged on the four sides of the upper surface of the bottom plate, sliding holes are formed in thefour sides of the inner part of the movable square plate, positioning columns are inserted into the sliding holes in a sliding mode, the middle of the upper surface of the movable square plate is fixedly connected with a hydraulic press downward-pressing main shaft, a fixing cylinder is fixedly connected to the middle side of the upper surface of the bottom plate, and bolt holes are formed in thefour sides of the middle of the fixing cylinder. A supporting cylinder is kept on the upper side of a conical cutting die hole, the lower side of the conical cutting die hole is closed by rubber movable joint pipes, external dust cannot enter the conical cutting die hole and is attached to a metal rod blank, so that when the metal rod blank is cut, external force is generated to the conical cutting die hole due to dust, and the quality of a metal rod and the conical cutting die hole is protected.

Description

technical field [0001] The invention relates to the technical field of metal rod cutting molds, in particular to a decompression and dust-proof mold for metal rod processing. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, etc. to obtain the required products. In short, molds are tools used to make shaped objects , this tool is composed of various parts, and different molds are composed of different parts. [0003] The existing metal bar processing die adopts conical cutting die holes to punch the outer surface of the metal bar blank, which can stamp the rough outer surface of the metal bar blank into a smooth surface, and the metal bar prototype can be stamped, but the conical The internal size of the shape cutting die hole must be precise when used, but because its design is exposed to the air, a large amount of dust particles are o...

[0003] The existing metal bar processing die adopts conical cutting die holes to punch the outer surface of the metal bar blank, which can stamp the rough outer surface of the metal bar blank into a smooth surface, and the metal bar prototype can be stamped, but the conical The internal size of the shape cutting die hole must be precise when used, but because its design is exposed to the air, a large amount of dust particles are often attached to its lower port and inner wall. The expansion pressure of the cutting metal rod blank in the shape cutting die hole increases, which will cause damage to the conical cutting die hole and the metal rod at the same time
