Examples
Fig. 1 is the utility model relates to a schematic diagram of a wax pattern module structure embodiment for spiral case, as shown in the figure, the utility model provides a wax pattern module structure for spiral case, including pouring basin wax matrix 1, cross gate wax matrix 2, ingate wax matrix 3 and spiral case wax matrix 4, pouring basin wax matrix 1 sets up at the upside of cross gate wax matrix 2, and the downside of cross gate wax matrix 2 is connected with a plurality of ingate wax matrix 3, and spiral case wax matrix 4 is connected with ingate wax matrix 2 through ingate wax matrix 3 and cross gate wax matrix 2 is perpendicular. The sprue cup wax mold 1 is of a conical table structure, the opening of the inner cavity 5 of the sprue cup wax mold 1 is gradually reduced from top to bottom, and the molten metal flows into the cross gate after reaching a proper pouring speed through the conical table structure, so that the pouring effect is good. The liquid degree of depth is big in the toper platform structure messenger pouring basin, can prevent the production of horizontal swirl and form perpendicular swirl to be favorable to separating dregs and bubble, prevent in it gets into the cross gate, improve the metal hydrostatic pressure, improve the compactedness of foundry goods.
The tapered bottom end of the sprue cup wax mold 1 is provided with a transition part 6 connected with the cross-gate wax mold 2, and two sides of the transition part 6 are both arc-shaped transition structures 7. The transition part 6 has a buffering function, the connection stability of the sprue cup wax mould 1 and the cross gate wax mould 2 is improved, the arc transition structure 7 shortens a highly turbulent flow area at the corners of the sprue cup and the cross gate, and the local resistance coefficient and the head loss at the corners are reduced.
