The device comprises a base; the base is provided with a support rod and a bracket; the support rod is provided with a bearing 1; a separation plate sleeves the bearing 1; a limiting plate 1 is arranged at the front end of the separation plate; an upper model is arranged at the upper end of the separation plate, and is provided with a pouring pipe; a lower model is arranged at the lower end of the separation plate; a limiting plate 2 is arranged on the side surface of the bracket; a two-way lead screw is arranged in the bracket; a fixed base is arranged at the bottom of the two-way lead screw; a stepper motor is arranged at the upper end of the bracket; a main shaft of the stepper motor is connected with the two-way lead screw; nut bases are respectively arranged at two ends of the two-way lead screw; an upper sand box and an upper support base are respectively arranged at two ends of the nut base at the upper end; a pressing column is arranged at the bottom of the upper support base; a lower sand box and a lower support base are respectively arranged at two ends of the nut base at the lower end; a seepage plate is arranged at the bottom of the lower sand box; and a molding core box is arranged at the upper end of the lower support base. The device is high in machining efficiency, low in production error, simple in operation and excellent in economic benefit.

Description

technical field [0001] The invention relates to the field of sand casting, in particular to a molding device for aluminum parts of automobile brakes. Background technique [0002] Sand casting refers to the casting method of producing castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, the casting molds are easy to manufacture. It can be adapted to piece production, batch production and mass production. It has been the basic process in casting production for a long time. [0003] The existing casting process is to divide the model consistent with the outer contour of the part into two parts, each placed on a workbench, each half of the model can be lifted and lowered on the workbench, and the sand box is placed on each workbench , then raise the model, fill in the molding sand and compact it, after the molding is finished, lower the m...

[0003] The existing casting process is to divide the model consistent with the outer contour of the part into two parts, each placed on a workbench, each half of the model can be lifted and lowered on the workbench, and the sand box is placed on each workbench , then raise the model, fill in the molding sand and compact it, after the molding is finished, lower the model, the middle of the two sand boxes will form half a mold cavity, and then make the inner cavity of the workpiece, that is, make a solid core, and then put into the mold cavity formed by two sandboxes, and inject the molten metal into the mold cavity. The gap between the mold cavity and the inner core is the pouring cavity of the workpiece. The molten metal enters the pouring cavity and cools to form a casting. The follow-up surface treatment is enough. This process requires at least two workbenches, and the fit between the sand boxes needs to be moved manually. Many, low production efficiency
