V-method casting production line

Abstract

The invention relates to a V-method casting production line, and belongs to the field of casting moulding. The V-method casting production line comprises a modeling system, a vacuum system, a pouringsystem, a sand conditioning system, a sand cooling system and a sand recovery system; the sand conditioning system comprises parallel and opposite risers; the top ends of the risers are rotationally connected with a turnover device; the turnover device comprises a carrying platform and a driving motor; an automatic clamping device is arranged on the carrying platform; a sand receiving funnel is arranged right below the carrying platform; a sand conveying belt is arranged below the sand receiving funnel; a casting conveying belt is arranged at one side of the carrying platform in the rotation direction; a gap enabling a casting not to fall off is reserved between the casting conveying belt and a circle formed by rotation of the carrying platform; the sand cooling system comprises a sand vibration screen; a material hoist is arranged below the discharge end of the sand vibration screen; a falling sand cooling barrel is arranged at the conveying tail end of the material hoist. The V-method casting production line has the advantage of carrying out sand cleaning on the finished casting without carrying out artificial manual cleaning on the finished casting.

Description

technical field [0001] The invention relates to the field of material casting, in particular to a V-method casting production line. Background technique [0002] V method casting, also known as negative pressure casting, is named after the prefix "V" of the English word Vacuum (vacuum). The biggest advantage it differs from traditional sand casting is that it does not use adhesives. V-method casting uses plastic film to seal the sand box, and the air in the mold is drawn out by a vacuum pumping system. There is a pressure difference between the inside and outside of the mold, making the dry sand dense and forming The required mold cavity is solidified by setting the core, closing the box, pouring and evacuating the casting, and the negative pressure is released, and the molding sand is then collapsed to obtain the casting. [0003] Vacuum molding is to use a thin thermoplastic film, heat it to the softening point, and then cover it on the model plate with holes drilled and ...

AI Technical Summary

Problems solved by technology

[0004] As far as the current situation is concerned, the number of sand grains used in the existing vacuum molding equipment is very large. After molding, the sand grains often need to be manually processed, which requires a lot of manpower and material resources. Moreover, the temperature of the sand grains after casting is often high, so it is impossible to process the sand grains. Rapid cooling, affecting production efficiency
