Closing method

Abstract

The invention discloses a box assembling method which is applied to the field of casting. The technology comprises the following steps: 1, placing the bottom surfaces of an upper box and a lower box onto a base plate and enabling the upper and lower boxes to enter into a turning station; 2, at the turning station, turning the upper box and cleaning pores and cavity of the upper box, placing a parting surface of the upper box onto the base plate and enabling the upper box to entering into a pouring and riser mounting station; 3, at the pouring and riser mounting station, cleaning a sand-scraping surface of a sand mould of the upper box, and cultivating and fixing a pouring bowl and a riser bush on the sand mould; 4, causing the lower box to enter into a box assembling station, utilizing a mechanical arm to position, grasping the lower box, moving the lower box to a box assembling floating rail and primarily positioning; 5, causing the upper box to enter into the box assembling station, utilizing the mechanical arm to grasp the upper box and move onto the lower box according to a positioning standard of the lower box, thereby finishing the box assembling; and 6, fastening the upper box and the lower box. Before the box assembling, the turning in advance is performed and a pouring port and a riser are cultivated and fixed, so that the problem of secondary pollution to the cavity of the sand mould after the box assembling is effectively solved.

Description

technical field [0001] The invention relates to a casting process, in particular to a box closing method. Background technique [0002] At present, in casting production, there are usually two ways to combine the upper box and the lower box. One method is to use a crane to lift the upper box, and after manually turning over, the sprue bowl, riser ring, etc. are cultivated, and then Use the closing pin to position the closing box; another common closing method is to turn the upper box over by the manipulator and then close the box directly by mechanically assisted positioning, and then cultivate the sprue bowl, riser ring and other accessories for pouring sand molds. part. [0003] Both of the above two commonly used methods of closing boxes have disadvantages to varying degrees. The first method is purely manual, with low production efficiency and great safety hazards; The head (the end of the casting sand core) is scratched, and in serious cases, the core head will be cru...

Problems solved by technology

[0003] Both of the above two commonly used methods of closing boxes have disadvantages to varying degrees. The first method is purely manual, with low production efficiency and great safety hazards; The head (the end of the casting sand core) is scratched, and in serious cases, the core head will be crushed, resulting in sand hole defects in the casting; Wrong box defects; the second method uses manipulators to eliminate some human factors in the process of turning over and closing the upper box, but it is easy to drop the cementing sand when the sprue bowl and riser ring are strengthened after the box is closed. It cannot be removed in the mold, and the secondary mold sand pollutes the cavity, causing defects such as sand holes and slag inclusions in the casting
