Metal casting mold capable of stabilizing internal air pressure based on high-end manufacturing

Abstract

The invention relates to the technical field of casting and discloses a metal casting mold capable of stabilizing internal air pressure based on high-end manufacturing. The metal casting mold comprises a mold body; a bearing air plate is arranged in the mold body; an extrusion rod is fixedly connected to the top of the bearing air plate; a lever is rotatably connected to the top of the extrusion rod; a ventilation rod is rotatably connected to the right side of the lever; an air baffle is arranged at the bottom of the ventilation rod; an air blocking wheel is arranged above the bearing air plate; an extrusion air box is slidably connected to the side face of an extrusion air plate; an air spring is fixedly connected to the right side of the extrusion air box through a guide pipe; the rightside of the air spring is fixedly connected with a linkage rod; and the left side of the linkage rod is fixedly connected with an expansion plate. According to the metal casting mold capable of stabilizing the internal air pressure based on high-end manufacturing, through cooperative use of the extrusion rod and the bearing air plate, the effect of preventing fluctuation of the internal air pressure of the mold body during mold exhausting is achieved.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a metal casting mold based on high-end manufacturing that can stabilize internal air pressure. Background technique [0002] Casting is an early metal thermal processing technology mastered by humans. It has a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC, and the technology has reached a very high level. Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. [0003] After casting the molten metal into the mold, since the molten metal will release gas when it cools, it is necessary to continuously exhaust the mold when the mold is cooling. However, during the process of exhausting, the gas pressure inside the mold will fluctuate. This causes unevenness on the surface of the molten metal as it cool...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a metal casting mold based on high-end manufacturing that can stabilize the internal air pressure. It has the advantages of preventing the internal air pressure of the mold from fluctuating when the mold is exhausted, and solves the problem of the existing metal mold. When the mold is exhausted, due to the fluctuation of the air pressure inside the mold, the surface of the molten metal will be uneven when it is cooled.
