Be applied to above-mentioned technical scheme, investment pattern tree die head location structure in, including three at least vertical runners, in the leading flank or the trailing flank of each vertical runner, each protruding location line is the matrix and arranges the setting.
The positioning structure is applied to each technical scheme, and in the positioning structure of the investment pattern tree die head, each protrusion positioning line is set to be a positioning line protruding by 0.5 MM.
The positioning structure is applied to each technical scheme, and in the positioning structure of the investment pattern tree-assembling die head, the front side surface and the rear side surface of each vertical pouring gate are respectively provided with 7 protruding positioning lines which are arranged in parallel.
The positioning structure of the investment pattern tree-assembling die head is applied to each technical scheme, and a cross-shaped knife wax pattern with a square inner sprue is respectively welded on a corresponding vertical pouring gate in a soldering iron heating mode.
The utility model has the advantages that:
the utility model discloses a be provided with a plurality of protruding positioning lines that are used for hindering the cross sword wax matrix that welds at the die head, and be provided with the square ingate that corresponds with protruding positioning line at each cross sword wax matrix, so, when hindering the welding, can align and hinder and weld the connection with protruding positioning line through the upper edge of square ingate; the scheme is simple and reliable, and easy to implement, only need on the mould of die head process out bellied location line can, alright make the die head of production all have and have bellied location line, it is clear and definite reliable to visualize. Moreover, due to the fact that the specific alignment base line is arranged, the inner sprue is not required to be reserved for a long time, other cost is hardly required, and the problems that the casting is easy to cut and the sprue residue is high in cutting can be perfectly solved; therefore, the product cutting blade adopts a resin grinding wheel cutting blade, and three workpiece casting products can be cut by one blade.
