Two layers of horizontal flow path cross sectional area ratio about 1.4:1；Enter the sectional area of cuboid of water A connection casting by casting volume and pouring for setting
The note time formulates, and length is depending on the arrangement position of casting, and the sectional area of one section of the block on connection crossing current road is by casting volume
Formulated with the duration of pouring of setting, length is depending on the arrangement position of casting；Enter section of one section of long cube of water B connection casting
Area by casting volume with setting the duration of pouring formulate, length 10mm-30mm, connection crossing current road one section of block sectional area with
It is consistent that what it was connected enters water sectional area；It is about 1.4 that adjacent two layers, which enter water section area ratio,:1；Rising head connects one section of long side of casting
The size of body can foundation《Cast handbook》Calculate, the linkage section of cuboid and cylinder is the mistake by square-section to circular cross-section
Structure is crossed, rising head afterbody cylinder dimensions can foundation《Cast handbook》Calculated, rising head side connection cuboid, its is specific
Size can be formulated according to casting structure demand；Above-mentioned all parts that constitute all are embedded in template, and template is rectangular parallelepiped structure,
Length and width are respectively 650mmx525mm, and thickness can be by 30mm-130mm.
The course of work of the present utility model：
A set of casting pattern includes two block models, and model respectively print off after sand mo(u)ld by moulding, and two pieces of sand mo(u)lds carry out matched moulds, matched moulds
Afterwards sprue cup, cross gate, sprue, flow-stopping sheet, crossing current road, enter water, rising head and casting portion formation cavity, molten iron is at first
Sand mo(u)ld is entered by sprue cup, cross gate is first reached, sprue is reached afterwards, by flow-stopping sheet flow direction crossing current road, reach afterwards into
Water, casting and rising head are full of by entering after water, bottom and upper strata are filled simultaneously.
Superiority of the present utility model：1st, the model structure is simple, is easy to make, has cylinder diameter local for EPB calipers
The characteristics of wall thickness uneven distribution is even, intactly carries out feeding, and the shrinkage defect of casting is greatly lowered, while this process program iron
