A telescopic sand box for a sand mold three-dimensional printer and its working method

Abstract

The invention belongs to the field of sand mold three dimensional (3D) printers, and discloses a telescopiform sand box for a sand mold three dimensional printer and a control method thereof. The telescopiform sand box for the sand mold three dimensional printer comprises box bodies, a base and a support; the box bodies are arranged on the base and detachably connected with the base, and the base is arranged on the bottom of the support; the box bodies comprise an inner box body and an outer box body; the inner box body is arranged in the outer box body, the inner box body comprises an inner upper part and n (n is greater than or equal to one) inner lower parts, and the inner lower parts are telescoped outside the inner upper part; and the outer box body comprises an outer upper part and n (n is greater than or equal to one) outer lower parts, and the outer lower parts are telescoped outside the outer upper part. According to the telescopiform sand box for the sand mold three dimensional printer, and the telescopiform structure is good in sealing and convenient to conduct sand box cleaning, so that the service life of a device is improved while the good operating environment of the device is guaranteed; and device limiting on the plant height is relieved, so that the application and promotion are facilitated.

Description

technical field [0001] The invention belongs to the field of sand mold three-dimensional (3D) printers, and particularly relates to a telescopic sand box for a sand mold three-dimensional printer and a working method thereof. Background technique [0002] The sand box of the existing sand mold 3D printer is set inside the printer, which is generally a sliding door structure. During sand printing, although the door of the sand box is closed, the sand in the sand box is still easy to leak from the gap of the sand box door. , resulting in the accumulation of sand and dust in the equipment, which seriously affects the normal operation and life of the equipment; if sealant is used to seal the gap, the sealant will be worn after one or two months of use, which still cannot effectively solve the problem of sand leakage. In addition, the existing sand box is an integrated structure, and the height of the box body is fixed. In addition to the height of the corresponding lifting mecha...

AI Technical Summary

Problems solved by technology

[0002] The sand box of the existing sand mold 3D printer is set inside the printer, generally with a sliding door structure. During sand printing, although the door of the sand box is closed, the sand in the sand box is still easy to leak out from the gap in the sand box door. , leading to the accumulation of sand and dust in the equipment, seriously affecting the normal operation and life of the equipment; if the gap is sealed with sealant, the sealant will be worn after one or two months of use, and the problem of sand leakage cannot be effectively solved

Moreover, the existing sand box is an integrated structure, and the height of the box body is fixed. In addition, the height of the corresponding lifting mechanism makes the overall height of the sand mold 3D printer relatively large, which is not conducive to printing operation and cost saving.
