Abstract
The utility model discloses an automobile brake disk synchronously eccentric casting die, which comprises an upper casting box, a casting core, a lower casting box and a reinforcing lug boss, and is characterized in that a synchronously-eccentric lug boss is arranged along the outer edges of the casting core. When the casting core is eccentric, the synchronously-eccentric lug boss can drive the reinforcing lug boss to be eccentric simultaneously, thereby solving the eccentricity of the reinforcing lug boss and a mounting hole, reducing the strength of machinery processing after casting, and improving the finished product rate of casting automobile brake disks.
Description
Technical field
The utility model relates to a kind of casting mould, and especially a kind of automobile brake disc casting mould belongs to the automobile mechanical field.
Background technology
The blank of automobile brake disc all adopts casting production, therefore the precision of casting mould directly influences the quality of brake disc, and existing casting mould generally is to be made of cope, core, drag box, core is directly as in the upper and lower sandbox, in casting process, because molten iron is to the impact of core during casting, and the influence of the factors such as case of expanding with heat and contract with cold, rise, core is easy to be subjected to displacement, therefore as easy as rolling off a log core and the last drag box of causing is laterally eccentric, has so just caused the reinforcement boss and the off-centre of strengthening installing hole on the boss of brake disc.This off-centre is irregular often, and what have can correct in follow-up mechanical processing process, and what have then can't correct, and therefore, has finally caused casting production efficiency low, and yield rate is low, wastes raw-material problem.
The utility model content
At being easy to generate eccentric problem in the existing brake disc foundry production, the utility model provides a kind of automobile brake disc with eccentric casting mould, this mould has designed a kind of with eccentric boss on core, when core is eccentric, should can drive with eccentric boss and strengthen boss off-centre simultaneously, thereby solve the problem of strengthening boss and installing hole off-centre.
The technical scheme that the utility model automobile brake disc is taked with eccentric casting mould is, it comprises cope, core and drag box, and in order to solve the problem of strengthening boss and installing hole off-centre, this mould has designed together eccentric boss in the outer of core.
Above-mentioned automobile brake disc is with eccentric casting mould, describedly is arranged on the outer of core with eccentric boss, with core be an integral body.The applicant analyzes, this sand core structure is when the casting brake disc, when molten iron impacted core and expands with heat and contract with cold, rises case, the same eccentric boss of this core can drive strengthened boss off-centre simultaneously, has therefore solved the eccentricity issues of strengthening between boss and the installing hole well.
Above-mentioned automobile brake disc is applicable to the casting of the automobile brake disc of all band reinforcement boss with eccentric casting mould.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of the utility model automobile brake disc with eccentric casting mould;
Fig. 2 is the vertical view of the utility model automobile brake disc with eccentric casting mould.
The specific embodiment
As depicted in figs. 1 and 2, a kind of automobile brake disc is with eccentric casting mould, and it comprises cope 1, core 3, and drag box 2 and reinforcement boss 5 have wherein designed together eccentric boss 4 on the core 3.
In the automobile brake disc foundry production, when molten iron impacted core 3 and expands with heat and contract with cold, rises case, it is eccentric simultaneously that the same eccentric boss 4 on this core 3 can drive reinforcement boss 5, therefore solved the eccentricity issues of strengthening between boss and the installing hole.
The utility model automobile brake disc with eccentric casting mould energetically meaning be, solved existing casting mould because the core displacement causes the eccentricity issues of strengthening between boss and the installing hole, reduce the intensity of casting back machining, improved the yield rate of automobile brake disc casting.
Claims (1)
1. an automobile brake disc is with eccentric casting mould, and it comprises cope, core, and drag box and strengthen boss is characterized in that, is provided with together eccentric boss along the outer of core.
