Rotating casting method capable of achieving any mold filling force by virtue of centrifugal force and gravity

Abstract

The invention discloses a rotating casting method capable of achieving any mold filling force by virtue of centrifugal force and gravity. According to the technical scheme, a rotating disk capable of rotating at any speed is constructed, the center of the rotating disk is a sprue gate around which a horizontal pouring gate is arranged, the outer side of the horizontal pouring gate is a die position, a die is arranged at the die position, and a gate of the die is connected with the tail end of the horizontal pouring gate; during casting, the rotating disk rotates at certain speed, and poured molten metal flows outwards along the pouring gate under the action of the centrifugal force, and is injected into the mold for mold filling. According to the rotating casting method, the limitation of conventional gravity to the mold filling force is broken, complex pressurization equipment is not required, and requirements on the precision of the equipment are greatly lowered; different mold filling pressure can be achieved only by adjusting the rotating speed of the rotating disk, convenience in adjustment, high adjustment speed and adjustment reliability are ensured, and the rotating casting method is a new mold filling pressure-adjustable casting method.

Description

Technical field: [0001] The invention belongs to the technical field of material processing, and in particular relates to a rotary casting method which utilizes centrifugal force and gravity to achieve arbitrary mold filling force. [0002] Background technique: [0003] Casting is a kind of metal thermal processing technology mastered by human beings earlier, with a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC, and the craftsmanship 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. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramics. Depending on the requirements, the methods used...
