Abstract
The utility model provides a multi-nozzle sand mold 3D printer and belongs to the technical field of sand mold printer designing and manufacturing. The upper portion of a mainframe is provided with a sand mold bin movable plate; sand funnel slide rails are provided with a sand funnel; a multi-nozzle printhead transverse slide rail and a multi-nozzle printhead vertical slide rail are provided with raster ruler closed loop feedback sensing elements A and B; and the multi-nozzle printhead transverse slide rail is provided with a multi-nozzle printhead. The working method of the multi-nozzle sand mold 3D printer is as follows: the multi-nozzle printhead is driven by transverse and vertical driving servo motors to perform reciprocating motion, during working, a figure needing to be printed is firstly input to a computer, the multi-nozzle printhead runs and spays glue at the same time according to the figure input beforehand, the sand funnel is driven by the driving servo motors to perform vertical motion and uniformly pave modeling sand at the same time, and a 3D sand mold is printed by repeating the previous steps. According to the utility model, multiple nozzles are adopted so that the area of single glue spraying is larger, the repeated positioning frequency is reduced, and the working efficiency is improved. The raster ruler closed loop feedback sensing elements are arranged so that the repeated positioning precision is improved, thus the dimension precision of the sand mold is improved, and the problems of conventional equipment are solved.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of sand mold printer.
Background technology
The sand mold printer using at home is at present pen type 2 nozzle printheads.When every layer of sand mold printing, one of them nozzle glue spraying, sketches the contours of the outline of figure.Another nozzle glue spraying is filled full figure.This kind of printer adopts Goode gridding order to control the track of shower nozzle, and ppi is very low, thereby makes sand mold surface roughness low.The surface of the work precision that impact is manufactured.Also exist in addition the area of a glue spraying of single head little and need resetting and adopt open loop control mode etc., so inefficiency.The positioning precision that is exactly in addition it arrives greatly positive and negative 0.01mm, causes the dimensional discrepancy of manufacture workpiece large.
Summary of the invention
For above-mentioned situation, the purpose of this utility model is to provide a kind of multi-jet sand mold 3D printer, solves the problems that existing product exists.
The utility model is to address the above problem taked technical scheme to be; The top of mainframe is with sand mold storehouse movable plate.At both sides, mainframe top sand hopper slide rail, on sand hopper slide rail with sand hopper.On sand hopper slide rail, with sand hopper, drive servomotor.At the rear portion of mainframe with the horizontal slide rail of multiinjector printhead, on the horizontal slide rail of multiinjector printhead with grating scale closed loop feedback sensing element A.On the horizontal slide rail of multiinjector printhead with multiinjector printhead.On one end of multiinjector printhead slide rail, with multiinjector printhead, laterally drive servomotor.Below the horizontal slide rail of multiinjector printhead with the longitudinal slide rail of multiinjector printhead.On the longitudinal slide rail of multiinjector printhead with grating scale closed loop feedback sensing element B.End at longitudinal slide rail longitudinally drives servomotor with multiinjector printhead.Method of work of the present utility model is; Multiinjector printhead can be reciprocating on horizontal and vertical slide rail under the drive of horizontal and vertical driving servomotor.Sand hopper is made front-rear reciprocation movement under sand hopper drive motors drives on sand hopper slide rail.The figure input computer of first needs being printed during work.Multiinjector printhead is according to the graph edge operation limit glue spraying of prior input.After having sprayed one deck, multiinjector printhead is return initial position fast, after sand mold storehouse movable plate moves down 0.3mm simultaneously, keeps motionless.Then sand hopper vertically moves uniform spreading cloth molding sand simultaneously under driving servomotor drives.After paving cloth completes, Quick-return, to initial position, then carries out glue spraying and sanding next time.Glue spraying place sand solidifies, and with sand mold, constantly increases, and prints three-dimensional sand mold.The utility model, owing to adopting multiinjector, makes the area of single glue spraying large, and the number of times that has reduced resetting has improved operating efficiency.Due to grating scale closed loop feedback sensing element, greatly improved the precision of resetting, thereby improved the dimensional accuracy of sand mold.It is a kind of desirable sand mold 3D printer.
