Low pressure casting machine

Abstract

The invention discloses a low pressure casting machine. The low pressure casting machine comprises a worktable, wherein an insulating furnace is arranged in the worktable; a riser tube is arranged inthe insulating furnace; a calibrating block is arranged on the top of the insulating furnace and is arranged on the outer side of the riser tube; a lower mold is arranged on the top of the worktable;an upper mold is arranged on the top of the lower mold; mounting holes are formed in the four corners of the top of the upper mold; and a mold jacking plate is arranged on the top of the upper mold. Alead screw drives a bushing to move upward so as to drive a pressure plate, the upper mold, the mold jacking plate and a finished product to move upward, a roller and a slide rail are movably locked,and a lug slides in a guide rail, so that the low pressure casting machine is stable to demold and does not damage the finished product. A double-shaft motor drives a carrying barrel and a connectingrod to rotate, and the carrying barrel rotates, so that heat of the finished product is dissipated more quickly; the connecting rod drives cleaning cotton to rotate to clean a lower cavity; and the low pressure casting machine is accurate to fix the position, convenient to use and high in casting quality if being used for loading and loading a mold.

Description

technical field [0001] The invention relates to the field of low-pressure casting machines, in particular to a low-pressure casting machine. Background technique [0002] Low-pressure casting refers to a casting method in which molten metal fills the cavity under pressure to form a casting. Because the pressure used is low, it is called low-pressure casting. The castings of low-pressure casting have dense structure and good mechanical properties, so they are widely used in castings such as automobile cylinder blocks, cylinder heads and wheel hubs. The low-pressure casting machine in the prior art, due to certain limitations of the equipment, the motion stability between the moving parts is poor, which often leads to a decrease in the precision of the casting; at the same time, the traditional low-pressure casting machine has a low degree of automation. , the castings cannot be taken out quickly, and the adaptability to molds of different specifications is also poor, and the...
