Abstract

The invention discloses a side-mounted machine arm type 3D sand mold printing equipment; it includes a frame body, a sand box, and a slideway; the inside of the frame body near the bottom is penetrated with the slideway, and the slideway is a rectangular structure; The sand box is slidably connected above the slideway; two parallel slide rails are arranged on both sides of the top of the frame body, and the two slide rails are matched and connected with two sliders, and the two sliders are connected There is a smoothing mechanism; one side of the frame body is provided with a machine arm structure, the machine arm structure includes a base, a main arm is connected above the base, a turntable is connected above the main arm, and a large arm is connected above the turntable, The big arm is provided with a rotating motor to drive the big arm to rotate; the present invention prints by setting the side-mounted machine arm and connecting the printing nozzle, avoiding printing through the slide rail together with the smoothing mechanism, and separately executing the printing job, increasing the printing efficiency.

Description

technical field [0001] The invention belongs to the technical field of sand mold 3D printing equipment, and in particular relates to a side-arm type 3D sand mold printing equipment. Background technique [0002] Sand mold 3D printing uses droplet jetting technology to print sand first, and then selectively spray viscous fluid on the sand surface, so that the casting sand is bonded to each other to form the cross section of the part, and then continuously circulate sand and In the process of spraying the binder, the area where the fluid is finally sprayed is bonded to form a three-dimensional sand mold due to the drying of the fluid, which realizes the rapid additive manufacturing of sand molds for casting. [0003] When printing, the existing 3D sand printers generally use a sliding structure on the top of the sand box, and a sliding nozzle on the sliding mechanism to achieve repeated printing work; however, this printing method needs to work successively with the sand and g...
