Automatic iron mold sand lined production line

Abstract

An automatic iron mold sand lined production line relates to a production line which is used when the iron mold sand is lined on a female mold in the production process of a crankshaft, and mainly aims at solving the problems that the conventional iron sand lined production line for producing the crankshaft is large in land occupation area, low in working efficiency and the like. The automatic iron mold sand lined production line comprises a double-station sand ejector, three mold turnover machines, two mold opening-closing machines, a perforation sand shakeout machine, a shifting machine, a female mold cooling device and a vibration sand shakeout machine; and the automatic iron mold sand lined production line also comprises a plurality of sections of tracks, a plurality of sections of casting line tracks and three sections of cart tracks, each section of tracks is fixedly disposed on a track support, each section of tracks is provided with a plurality of driving wheels and a plurality of driven wheels, the driving wheels are connected with one another through a chain, the driving wheels and the driven wheels are disposed at intervals, a plurality of motors are fixedly dispsed on the track support, and the driving wheels are connected with chain wheels which are disposed on power output shafts of the motors through chains. The automatic iron mold sand lined production line has the advantages of small land occupation area, low labor intensity of workers, good safety and fast production speed.

Description

Technical field: [0001] The invention relates to an assembly line used for sand-coating a female mold iron mold in the production process of a crankshaft. Background technique: [0002] At present, there is a certain distance between the female mold support of the upper box station and the female mold support of the lower box station of the double-station sand injection machine on the iron mold sand-coated line for producing crankshafts, so the iron mold sand-coated line needs to be installed. The box enters the track and the lower box leaves the track, so that the equipment occupies a large area, requires a lot of investment, and the work efficiency is low; the natural cooling of the upper box mold and the lower box mold is slow and the effect is poor; The cylinder rod of the oil cylinder is easy to break, which affects the normal production; there are only automatic transmission wheels on the track between the vibration shakeout machine and the punching shakeout machine, a...

Problems solved by technology

[0002] At present, there is a certain distance between the female mold support of the upper box station and the female mold support of the lower box station of the double-station sand injection machine on the iron mold sand-coated line for producing crankshafts, so the iron mold sand-coated line needs to be installed. The box enters the track and the lower box leaves the track, so that the equipment occupies a large area, requires a lot of investment, and the work efficiency is low; the natural cooling of the upper box mold and the lower box mold is slow and the effect is poor; The cylinder rod of the oil cylinder is easy to break, which affects the normal production; there are only automatic transmission wheels on the track between the vibration shakeout machine and the punching shakeout machine, and it is impossible to send the upper box mold and the lower box mold to the vibration shakeout station ;Manually open and close the iron sand box, which is labor-intensive and unsafe; manually flip the upper box mold and the lower box mold by 180°, and the turning speed of the upper box mold and the lower box mold is slow
