Summary of the invention
The objective of the invention is to solve the big sandbox casting light casting sandbox utilization rate big shortcoming of molten iron pressure low, that single running gate system was born when the crowd cast; Provide a kind of rational in infrastructure; The moulding time is short; Save the energy, can make to ensure that under the situation that does not reduce product quality product yield, the casting that can enhance productivity use multi-functional sandbox.
Multi-functional sandbox is used in this casting; At the bottom of the tank wall and case around comprising; The shaped steel of reinforcing usefulness is installed around the tank wall, it is characterized in that the partition panel of setting is arranged in the sandbox; Sandbox is separated into several mutual disconnected sand buggies, and each sand buggy independently vacuumizes docking port in the side or/and the bottom surface all has.
When the sidewall of sand buggy and tank wall overlap, on the sidewall of intersection, be equipped with at a distance from the sand vent board, between sand vent board and tank wall, screen cloth is housed, at a distance from the sand vent board through the outer air flue of tank wall with vacuumize docking port and communicate.
At the bottom of the case of each sand buggy; The steel pipe parallel with the bottom surface is housed, and steel pipe is divided into the section of bleeding and canned paragraph, and canned paragraph is fixed on the tank wall; The section of bleeding is connected with knot that can be undone by a pull with canned paragraph; Be drilled with several pores on the section of the bleeding steel pipe, the section of bleeding steel pipe external application screen cloth twines, the outer end of canned paragraph steel pipe through the outer air flue of tank wall with vacuumize docking port and communicate.
The angle is bent into two obtuse angles or a circular arc around the sandbox, or three limits of isosceles trapezoid add two little circular arcs.The angle that increases corner helps the jolt ramming of molding sand.
The present invention has increased partition panel in sandbox, sandbox just is divided into a plurality of sand buggies like this, can be according to the suitable sand buggy size of different foundry goods size adjustment.Vacuumize docking port because each sand buggy has had own independent, the air between each sand buggy is not connected, and independent negative pressure system has guaranteed that the negative pressure in each sand buggy is independent of each other, and can adjust according to different needs.Change the screen cloth of being blocked by dust for ease, the present invention changes the channel-section steel of sandbox bottom into flanged (FLGD) steel pipe, a plurality of pores that distribute on the steel pipe, and with a shutoff of steel pipe.Steel pipe twines with 200 eye mesh screens, tightens fixing getting final product with iron wire.Conveniently replaced screen cloth.Different foundry goods are done and large scale sandbox customized with regard to unnecessary can taking into account for sandbox by castings production producer, worry again that simultaneously big sandbox can reduce the risk of product percent of pass when producing many light castings.Improved the versatility of production line, effectively avoided the overlapping investment of production line, reduced the disappearance mould and gone into gate threshold.
