Description

Aluminum nickel cobalt magnet forming equipment for permanent magnet sucker Technical Field The utility model relates to the technical field of casting molding of aluminum nickel cobalt magnets, in particular to aluminum nickel cobalt magnet molding equipment for a permanent magnet sucker. Background The molding equipment of the alnico magnet is mainly used for producing magnet components required by permanent magnetic suction cups, common molding equipment is casting equipment, the casting equipment can be processed and produced into different sizes and shapes, molten alnico alloy is poured into a mold for cooling molding, and then the crystal structure and the magnetic property are optimized through heat treatment. At present, because the magnet part of permanent magnet chuck is the sheet structure of center trompil, alnico magnet former is the shaping in-process of pouring, and alnico magnet of sheet structure can adsorb in forming die to lead to the drawing of patterns difficulty of alnico magnet, and alnico magnet need natural cooling to normal atmospheric temperature state just can the drawing of patterns after pouring, and alnico magnet cooling rate is slow at normal atmospheric temperature state, leads to the shaping machining efficiency of alnico magnet low. Disclosure of utility model The utility model aims at overcoming the defects of the prior art, and provides aluminum nickel cobalt magnet forming equipment for a permanent magnet sucker, which realizes the functions of cooling and demolding an aluminum nickel cobalt magnet by matching a metal cooling pipe structure with a demolding plate structure and solves the problems of low cooling speed and difficult demolding of the aluminum nickel cobalt magnet. The technical scheme is that the aluminum nickel cobalt magnet forming equipment for the permanent magnet sucker comprises a lower die and an upper die fixed at the top end of the lower die, wherein inner dies are fixedly embedded in the lower die and the upper die, casting grooves are formed in the top end of the inner die in a rectangular array, concave holes are formed in the bottom wall of the casting grooves, stripper plates are fixedly inserted in the concave holes in an anastomotic manner, cooling metal pipes are fixedly embedded in the bottom end of the lower die, and the inner dies are resin bonded sand dies and can bear the high temperature of nickel cobalt magnets. Preferably, the bottom of the lower die is provided with a plurality of bolts in a rectangular array, and nuts are sleeved on the top ends of the bolts through the threads of the upper die. Preferably, a pouring hole with a funnel-shaped structure is formed in the top end of the upper die, and the pouring holes are respectively communicated with the pouring grooves. Preferably, a water storage tank is arranged on one side of the lower die, and a water inlet pipe is fixedly arranged at the bottom end of the side wall of the water storage tank. Preferably, the cooling metal pipe and the water inlet pipe are fixedly provided with water pipe connectors which are connected with each other, and the water pump connected with the water inlet pipe is embedded in the water storage tank.
