fig. 2 is the utility model relates to a mould for casting of car brake disc's structural schematic.

In the figure: the sand mold casting device comprises a lower mold 1, an upper mold 2, an air box 3, a sand mold fixing frame 4, a sand mold 5, a pouring opening 6, a sand core 7, heat dissipation holes 8, a filter screen 9, a sealing plate 10, an exhaust fan 11, screws 12, a guide groove 13, a guide plate 14 and a handle 15.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

The mould for casting the automobile brake disc comprises a lower mould 1 and an upper mould 2, wherein the lower mould 1 and the upper mould 2 are connected through a guide mechanism, the lower mould 1 and the upper mould 2 are both made of stainless steel, the shape and the size of the lower mould 1 and the upper mould 2 are the same, air boxes 3 fixedly connected with the lower mould 1 and the upper mould 2 are respectively penetrated through the middle parts of two side surfaces of the lower mould 1 and the upper mould 2, the air boxes 3 are designed to be square, the air boxes 3 are made of stainless steel, sand mould fixing frames 4 are jointly fixed on the two air boxes 3 on the lower mould 1 and the upper mould 2, each sand mould fixing frame 4 is penetrated through by the air box 3, a sand mould 5 is fixed in each sand mould fixing frame 4, a pouring opening 6 is arranged on the sand mould 5 on the upper mould 2, a sand core 7 is fixed in the middle part of the sand mould 5 on the upper mould 2, heat dissipation holes, every 3 fronts of bellows are equipped with closing plate 10, every closing plate 10 middle parts are all inlayed and are had air discharge fan 11, and every 10 four corners of closing plate all are equipped with its screw 12 with 3 fixed connection of bellows, can make lower mould 1 and last mould 2 carry out accurate butt joint through guiding mechanism, reduce because lower mould 1 with go up the mould 2 position uneven and produce poor product, the filter screen 9 and the 8 cooperation air discharge fans 11 of louvre bottom of bellows 3 can dispel the heat with foundry goods in the sand mould 5 fast, can make the quick cooling shaping of foundry goods, the casting rate of brake disc has been improved.
