SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough and provide a with low costs, be applicable to the saving type pouring mechanism of small-size product.

In order to achieve the above purpose, the solution of the present invention is:

an economical casting mechanism, comprising: sprue bush and sprue spreader, be equipped with a boss on the sprue bush, this boss cooperation is fixed on the fixed die plate, and this sprue bush has a sprue, the sprue spreader sets up on movable mould benevolence, and the top of this sprue spreader is equipped with the convex part that corresponds the sprue, and the convex part both sides are equipped with the sprue spreader, the sprue spreader has a protruding wall, and this protruding rampart cooperation is on movable mould benevolence.

Furthermore, the sprue is of a tapered structure gradually expanding from top to bottom, and the spreader cone is of a tapered structure matched with the sprue.

After the structure of the oil adding device is adopted, the utility model discloses saving type pouring mechanism sets up the boss of cooperation on the fixed die plate on the runner cover, and the spreader cone then sets up the protruding wall of cooperation on movable mould benevolence, and the runner cover and the spreader cone of this kind of structure need not to use the fix with screw in the mould, and spreader cone and runner cover just can design the smaller so, and the stub bar of product will be smaller like this, and the consumption of molten metal is just little, and the diameter of spreader cone can be set for according to the required ratio of foundry goods and the weight of die casting equally. The utility model discloses saving type casting machine constructs simple structure, and the simple workable of processing technology compares in traditional die casting die, the utility model discloses can do small-size product, be applicable to the preparation of small-scale mould, practice thrift the mould cost, reduce the production of secondary metal material. The sprue of the sprue bush can ensure smooth action of the injection punch head, ensure stable transmission and filling of metal liquid pressure, the diameter of the sprue bush can be selected according to the required ratio of a casting and the weight of a die casting, the sprue corresponds to the sprue, the sprue is a feed inlet, and the sprue is divided into the sprue cavity by the sprue divider after feeding, so that the sectional area of the sprue can be adjusted, the flow direction of the metal liquid can be changed by the sprue divider, and the consumption of the metal liquid is reduced
