Abstract
The invention relates to an industrial sand mold printer, and in particular relates to a three-dimensional (3D) multi-nozzle sand mold printer. A sand mold bin movement plate is arranged on the upper part of a main frame. A sand hopper is arranged on a sand hopper sliding rail. Grating ruler closed-loop feedback sensing elements A and B are arranged on a horizontal multi-nozzle printing head sliding rail and a longitudinal multi-nozzle printing head sliding rail. A multi-nozzle printing head is arranged on the horizontal multi-nozzle printing head sliding rail. The 3D multi-nozzle sand mold printer adopts a working method of driving the multi-nozzle printing head to reciprocate through a horizontal driving servo motor and a longitudinal driving servo motor. When the printer works, a graph needing to be printed is input into a computer; the multi-nozzle printing head operates and sprays glue simultaneously according to the pre-input graph; the sand hopper moves longitudinally under the driving of the driving servo motors, and uniformly lays molding sand; a 3D sand mold is printed in a circulating manner. By the adoption of a plurality of nozzles, the glue spraying area each time is large, the repeated positioning frequency is reduced, and the working efficiency is improved. By the adoption of the grating ruler closed-loop feedback sensing elements, the repeated positioning accuracy is improved, so that the dimensional accuracy of the sand mold is improved. The problems of existing equipment are solved.
Description
Technical field
The present invention relates to industrial sand mold printer, be specially a kind of multiinjector sand mold 3D printer.
Background technology
The sand mold printer used at home at present is pen type 2 nozzle print head structures.When every layer of sand mold printing, one of them nozzle glue spraying, sketch 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 the 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 manufacturing workpiece large.
Summary of the invention
For above-mentioned situation, the purpose of this invention is to provide a kind of multi-jet sand mold 3D printer, solve the problems that existing product exists.
The present invention addresses the above problem taked technical scheme to be; The top of mainframe is with sand mold storehouse movable plate.In both sides, mainframe top with the sand hopper slide rail, on the sand hopper slide rail with sand hopper.Drive servomotor with sand hopper on the sand hopper slide rail.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 the multiinjector printhead.Laterally drive servomotor with the multiinjector printhead on an end of multiinjector printhead slide rail.Below the horizontal slide rail of multiinjector printhead with the vertical slide rail of multiinjector printhead.On the vertical slide rail of multiinjector printhead with grating scale closed loop feedback sensing element B.End at vertical slide rail vertically drives servomotor with the multiinjector printhead.Method of work of the present invention is; The 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 the sand hopper drive motors drives on the sand hopper slide rail.First will need the figure input computer of printing during work.The multiinjector printhead is according to the graph edge operation limit glue spraying of prior input.After having sprayed one deck, the multiinjector printhead is return initial position fast, and sand mold storehouse movable plate keeps motionless after moving down 0.3mm simultaneously.Then sand hopper vertically moves uniform spreading cloth molding sand simultaneously under the 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 present invention, 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.
