Abstract

The invention discloses novel low-pressure casting equipment. The novel low-pressure casting equipment comprises a fixing bracket, a heat preservation furnace, a crucible and an air cooler; the heat preservation furnace and the air cooler are both fixedly arranged in the fixing bracket; the crucible is fixedly arranged in the heat preservation furnace; a vacuum cavity is formed between the crucible and the heat preservation furnace; a sealing cover is fixedly arranged at the top end of the heat preservation furnace, a fixing frame is fixedly arranged in the middle of the top end of the sealingcover, and a frame cover is hinged to the top end of the fixing frame; a mold is fixedly arranged in the fixing frame, the bottom end of the mold is fixedly connected with the top end of a liquid rising pipe, and the bottom end of the liquid rising pipe is arranged at the bottom of the inner wall of the crucible; and an air outlet pipe is arranged at the bottom of the side of the fixing frame ina penetrating mode. According to the novel low-pressure casting equipment, the air cooler and a circulating fan can cooperate with water cooling of the mold to cool the mold, the temperature loweringspeed is increased, the circulating fan can enable cold air to form convection in the fixing frame, heat exchange is more thorough, and then the cooling speed and the machining efficiency of the moldare increased.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a new type of low-pressure casting equipment. Background technique [0002] Low pressure casting is a method of filling a cavity with liquid metal under pressure to form a casting. Because of the lower pressure used, it is called low pressure casting. Its characteristics are: liquid metal filling is relatively stable; castings have good formability, which is conducive to the formation of hair culture with clear outlines and smooth surfaces; castings are densely organized and have high mechanical properties; improve the process yield of raw materials; because of mechanization and automation Operation, labor intensity is reduced, and production efficiency is greatly improved. [0003] The existing low-pressure casting equipment mold is generally cooled by water cooling, and the cooling speed is slow, which in turn leads to low processing efficiency, and the existing low...
