Abstract

The invention discloses a lower mold positioning device. The lower mold positioning device comprises a worktable; an insulation furnace is arranged in the worktable; a liquid rising pipe is arranged in the insulation furnace; a calibration block is arranged at the top of the insulation furnace, and is arranged on the outer side of the liquid rising pipe; a lower mold is arranged at the top of theworktable; a compressed gas inlet pipe is arranged on one side of the top of the insulation furnace; a lower molding cavity is formed in the lower mold; the lower mold is divided into two parts; sideplates are arranged on the two sides of the top of the worktable; the calibration block is a square block; a groove is formed in the bottom of the lower mold; and a liquid inlet is formed in the groove. Through arrangement of the calibration block and cooperation between a clamping block and a clamping plate, a lifting handle, the position of the replaced lower mold is precisely fixed, the installation is convenient, and the position is precise.

Description

technical field [0001] The invention relates to the field of low-pressure casting machines, in particular to a lower mold positioning device. 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 casting precision, poor adaptability to molds of different specifications, and low production efficiency . [0003] Therefore, it is necessary to invent a lower mold positioning device to solve the above problems. Contents of the invention [...
