A lost foam casting production line

Abstract

The invention discloses a lost foam casting production line and mainly aims to solve the problems that a cooling machine is bad in cooling effect, a turning angle of a sand box turning machine is small and the like in a conventional lost foam casting production line. The lost foam casting production line comprises a hydraulic turning machine, wherein a roller way conveyor connected with two sides of the hydraulic turning machine is connected with two transfer trolley tracks; bidirectional drive transfer trolleys are arranged on the transfer trolley tracks; a three-stage separator in front of the hydraulic turning machine is connected with a permanent magnet separator through a bucket elevator; the permanent magnet separator is connected with a spiral conveying cooling machine; the spiral conveying cooling machine is connected with a second bucket elevator; the second bucket elevator is connected with a storage bin; the storage bin is connected with a third bucket elevator, a belt conveyor and a modeling storage bin; a modeling machine is respectively connected with the transfer trolley tracks and a pouring swing table through roller way conveyors; the pouring swing table is connected with the transfer trolley tracks through the roller way conveyors. The lost foam casting production line has the advantages that the spiral conveying cooling machine is good in cooling effect, and the turning angle of the hydraulic turning machine is large.

Description

Technical field: [0001] The invention relates to a lost foam casting production line. Background technique: [0002] The existing lost foam casting production line includes sand treatment equipment and sand box circulation line. The sand processing equipment mainly includes: screening machine, hoist, permanent magnetic separator, cooling machine, belt conveyor, and storage bin. The sand box circulation line includes: sand box, molding machine (vibration table), transfer vehicle, hydraulic push box system, transfer vehicle track, turning machine, etc. Its disadvantage is that the sand boxes are connected end-to-end next to each other on the production line, and the movement of the sand boxes is pushed by hydraulic oil cylinders. If one is missing, the entire circulation line cannot run. Because the sand boxes are connected end to end, and the sand boxes are welded by steel, the temperature difference in different seasons is large, and the length of the sand boxes also chang...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the sand boxes are connected end to end one by one on the production line, and the sand boxes are moved by hydraulic cylinders. If one is missing, the entire circulation line cannot run

In addition, the molding machine described above has a complex structure and consumes a lot of energy, and it cannot compact the sand and fill it horizontally to every corner of the casting cavity, causing defects at the concave corners of the casting

The cooling effect of the cooling machine is not good

The sand box turning machine can only clamp the bottom of the sand box, and the sand box is easy to fall off after turning over, causing danger; in addition, its turning angle is small, and all the workpieces and sand in the sand box cannot be poured into the separator ; Moreover, it will be spilled outside the separator when it is dumped, and it needs to be cleaned manually, which is labor-intensive

The transfer vehicle mentioned above can only transfer the sand box, but cannot transport the sand box
