Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 4-7, a clamp piece pouring system comprises a pouring cup 1, a horizontal pouring gate 2 and a vertical pouring gate 3 which are sequentially connected to form a runner of molten metal, wherein the vertical pouring gate 3 is arranged in two and symmetrically arranged by the horizontal pouring gate 2, an upper pouring gate 4 and a lower pouring gate 4 are arranged on the same side of the vertical pouring gate 3, specifically, the two pouring gates 4 on the same side are respectively connected with two clamp pieces 5, the clamp pieces 5 are symmetrically arranged by the pouring gates 4, the clamp pieces 5 are vertically arranged, the upper pouring gate 4 and the lower pouring gate 4 are respectively connected with two hot-junction positions A of the clamp pieces 5, and a gap between hot-junction positions B of the two clamp pieces 5 connected by the upper pouring gate 4 and the lower pouring gate 4 on the same vertical pouring gate 3 is connected by a feeding head 6. The clamp piece 5 is arranged and placed, and batch casting quantity is provided, so that casting efficiency is improved.

The runner 4 sets up to T type structure, set up to two symmetrical bulge 41 in the one end of runner 4, two bulge 41 are connected with the side of the one end hot junction A department of clamp spare of both sides respectively, and runner 4 top surface and the runner 4 bottom surface of downside at the upside all are provided with protruding 7, after forming the mould shell, protruding 7 can form upper groove and lower groove, upper groove can collect the surface dross in the molten metal flow, improve the purity degree of molten metal, the lower groove can mobile phone molten metal in the impurity of subsidence, further improvement molten metal's purity degree, and then reduce shrinkage cavity, the defect of slag inclusion, thereby improve the pouring quality of clamp spare foundry goods.
