Efficient horizontal parting type removable flask molding machine and molding method thereof

Abstract

The invention relates to an efficient horizontal parting type removable flask molding machine and a molding method thereof. A lower molding flask module is arranged on a rack and comprises a lower enclosing frame. A lower push plate is slidably arranged in the lower enclosing frame. The lower enclosing frame is connected with a first driving device. The lower push plate is connected with a second driving device. The efficient horizontal parting type removable flask molding machine further comprises an upper molding flask module. The upper molding flask module comprises an upper enclosing frame fixed to the rack. An upper push plate is slidably arranged in the upper enclosing frame and connected with a third driving device. The efficient horizontal parting type removable flask molding machine further comprises a sand blasting nozzle seat fixedly connected with the upper enclosing frame, and the sand blasting nozzle seat is connected with a pressure sand blasting system. The upper enclosing frame and the lower enclosing frame are provided with sand inlet channels communicating with the pressure sand blasting system correspondingly. Attaching air bags are arranged on the lower surface of the upper push plate, and the upper surface of the lower push plate correspondingly; pressure sensors are arranged on the surfaces of the attaching air bags; and the upper enclosing frame and the lower enclosing frame are internally provided with limit switches correspondingly. The influences of gas in a molding flask on sand blasting and compaction are avoided, the uniformity of molding sand compaction is high, and the size, shape and precision of a poured casting are well ensured.

Description

technical field [0001] The invention relates to a sand molding machine for casting, in particular to a high-efficiency horizontal split-out box molding machine and a molding method thereof. Background technique [0002] Sand casting is a casting method that produces castings in sand molds, and is widely used in the production of castings of steel, iron and most alloys. The main function of the equipment used to make sand molds is to fill the loose sand into the sand box, and compact the sand in the sand box by compaction, so that the sand has the necessary strength during transportation or casting. [0003] The horizontal split type out-of-box molding machine does not require a large number of sand boxes and many auxiliary machines, and has strong process adaptability and low investment. As a kind of molding equipment used to produce medium and small castings, the horizontal split molding machine has been widely used in our country. However, at present, the horizontal part...
