A four-station mobile trolley-type v-method molding production line

Abstract

The invention discloses a four-station moving trolley type V method molding production line. The four-station moving trolley type V method molding production line comprises a rack, shakeout hoppers and a sand bin; the shakeout hoppers are connected with the sand bin through a sand returning pipeline; the sand bin is provided with a cyclone sand suction mechanism capable of enabling the negative pressure to be formed in the sand bin, and accordingly molding sand in the shakeout hoppers is sucked into the sand bin; two sand discharging hoppers are arranged on the sand bin and are both provided with deluge sand adding devices; two slide rails are arranged below the sand bin; two molding trolleys are arranged on each slide rail, located on the two sides of each deluge sand adding device correspondingly and capable of sliding along each slide rail and entering the position below the corresponding deluge sand adding device; the two sides of the sand bin is provided with second slide rail bodies perpendicular to the slide rails; and the second slide rail bodies are provided with a film covering device which can slide along the second slid rail bodies and thus is arranged above the molding trolleys in a covering mode. Compared with the prior art, the four-station moving trolley type V method molding production line achieves four-station continuous machining, meanwhile, used sand is recycled in a cyclone negative pressure mode, and natural cooling is achieved; and quick engagement of molding and recycling processes is achieved, so that production is conducted continuously.

Description

【Technical field】 [0001] The invention belongs to the technical field of aluminum alloy door frame processing equipment, in particular to a four-station moving trolley-type V-method molding production line. 【Background technique】 [0002] Due to the characteristics of its use, aluminum alloy doors are required to have a flat and smooth appearance, be able to withstand a certain load, have a small fit gap and be flexible to open. Today, the V method is generally used. V-method modeling is to place the mold plate on the mold plate holder, cover the mold plate with a plastic film that is baked in a plastic state, then place the sand frame and fill it with sand, and the air in the sand is extracted by the vacuum pumping mechanism. Due to the effect of pressure difference, the sand has a higher hardness, forming upper and lower molds with cavity shapes corresponding to the mold plate. After closing the upper and lower molds, inject aluminum alloy casting liquid into the cavity sh...

Problems solved by technology

[0003] However, the existing V-method molding production lines are all double-stations, which are produced by two molding wheels, which have low work efficiency and high energy consumption.

At the same time, the old sand in the existing production line is transported to the sand warehouse by the hoist after being cooled. This process will generate a lot of dust and because the molding sand has a high temperature after pouring the casting liquid, it will consume a lot of time and cost to wait for it to cool naturally. , affecting the continuity of production, resulting in low processing efficiency, and the use of cooling systems will increase equipment costs, so it cannot be adapted to production
