Abstract

The invention discloses a stepping type casting wax extrusion device. The stepping type casting wax extrusion device comprises a channel steel base, a door frame, a material storage barrel, a straight line stepping motor, a lead screw, a feeding nut, a fixed cover, a fixed plate, a piston, a heating pipe, a thermocouple and a controller. The straight line stepping motor drives the lead screw to rotate; as the feeding nut is fixed, the lead screw moves downward along the feeding nut, so that the piston moves downward; meanwhile, the controller controls the heating pipe to heat wax in the material storage barrel so as to melt the wax; under the thrust action generated by downward movement of the piston, the molten wax is extruded through a discharge pipe. The device is simple in structure, wax which is extruded in a pure stepping manner is uniform and continuous, no bubble is generated, and the quality of a wax mould is improved, so that the quality of a casting is improved.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a step-by-step wax extrusion device for casting. Background technique [0002] Wax mold precision casting, also known as lost wax casting or investment casting, the specific casting method is: first make a model of the casting to be made with wax material, and weld the model to the sprue rod with the same material to make Dip the module (when the casting is large, it can be a single group), dip the refractory paint (a mixture of water glass or silica sol and fine sand) on the surface of the module, and then sprinkle refractory sand, (dip and sand should be repeated several times , so that the sand layer is thick enough), after it is dry and solidified, heat the mold group, release the wax material from the gate, form an empty shell, roast the empty shell to make it a strong mold shell, and pour the metal liquid from the pouring It is poured into the mouth, and after condensation, it become...
