Abstract
The invention relates to an extrusion mold, in particular to a pneumatic type deep-hole vertical extrusion mold capable of realizing horizontal movement of an upper mold and provided with a dovetail slide, and aims to solve problems that equipment closing heights cannot meet conventional mold design for production of extrusion pieces with longer shapes and deeper inner holes currently and production costs are high. An upper mold assembly is mounted at the lower end of a sliding mechanism, a pneumatic mechanism is mounted at one end of the sliding mechanism, a locking mechanism is connected with the sliding mechanism, a lower mold assembly is located right below the upper mold assembly, and a mold aligning device is mounted in a cavity formed after buckling of the upper mold assembly and the lower mold assembly and is moved out during working of the mold. The upper mold assembly of the mold can move horizontally, so that the working space of equipment in the height direction is increased; after the upper mold assembly is removed from a space above the lower mold assembly, the space above the lower mold assembly becomes open space, and workpieces are ensured to be taken away from the space above the lower mold assembly. The mold is used for extruding the workpieces with longer shapes and the deeper inner holes.
Description
technical field [0001] The invention relates to a deep-hole vertical extrusion die, in particular to a horizontally moving deep-hole vertical extrusion die with a dovetail slideway pneumatic upper die, which belongs to the technical field of mechanical processing stamping professional die design. Background technique [0002] Extrusion is a less or no cutting process for forging. For conventional extrusion dies, the lower die assembly is fixed to the lower workbench of the equipment, and the upper die assembly is fixed to the upper slider of the equipment. Regardless of the upper die assembly or the lower die assembly, the horizontal direction relative to the equipment is fixed. Only the upper The die assembly moves up and down with the upper slider of the equipment, and the closing height of the extrusion equipment should be greater than the height of the lower die assembly plus the height of the workpiece plus the height of the upper die assembly, otherwise the workpiece c...
