Abstract
The utility model provides a kind of hot-die of brake block of disk brake, comprise patrix, counterdie and core rod, patrix is fixed on upper bolster, patrix is cover half, counterdie is dynamic model, counterdie has the die cavity running through counterdie up and down, die cavity is several of rectangular array, a core rod is equipped with in each die cavity, the relative counterdie of core rod can move up and down, whole core rod is fixed on the core rod holder that is positioned at below counterdie, the die work face of the patrix that each die cavity is just right is arranged the boss to lower convexity, boss be arranged at be placed in die cavity light plate fabrication hole directly over to make the boss when mold pressing enter steel plate fabrication hole.Counterdie is arranged multiple die cavity, therefore once can the multiple brake block of mold pressing.Because boss is arranged in steel plate fabrication hole when mold pressing, therefore reduce the pressure differential of friction material pressure that mold pressing makes steel plate fabrication hole place corresponding and other parts friction material, friction material is organized more even, improve the performance of brake pad.
Description
Technical field
The utility model relates to the production technical field of the brake block of disk brake, is specifically related to a kind of hot-die of brake block of disk brake.
Background technology
Automotive brake can produce the brake force hindering vehicle movement or movement tendency, and automobile brake used is nearly all friction-type, can be divided into drum-type and the large class of disc type two.Spinner member in drum type brake friction pair is brake drum, and its working surface is the face of cylinder; The brake disc of spinner member then for rotating of disk brake take end face as working surface.The brake block of disk brake comprises steel plate 1 and brake pad 2, and brake pad is connected on steel plate, and brake pad is made up of friction material, is compressed on brake disc and produces friction, thus reach the object of vehicle deceleration brake during brake.
The hot pressing film of the brake block of disk brake comprises upper die and lower die and core rod, and patrix is cover half, and counterdie is dynamic model, counterdie has the die cavity running through counterdie up and down, and core rod is arranged in die cavity and can moves up and down.Existing counterdie die cavity is only one, therefore causes production efficiency low.In heat pressing process, steel plate and friction material are placed in the die cavity of hot-die, carry out mold pressing.Working face due to hot-die patrix is plane, in hot pressing, have friction material emerge from steel plate fabrication hole and form protruding 3, brake block after mold pressing as shown in Figure 1, need in subsequent handling, projection to be removed, form brake block as shown in Figure 2, this adds increased operation, also cause the waste of friction material simultaneously.In addition, due to the existence of fabrication hole on steel plate, the friction material pressure making fabrication hole place corresponding in mold process is little compared with other parts friction material pressure, and this just causes whole brake pad uneven microstructure, produces harmful effect to the performance of brake pad.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of hot-die of brake block of disk brake, enhances productivity, and reduces the consumption of friction material in production process, reduces brake block production process, improves brake pad performance.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of hot-die of brake block of disk brake, comprise patrix, counterdie and core rod, patrix is fixed on upper bolster, the lower surface of patrix is die work face, die work face is plane, patrix is cover half, counterdie is dynamic model, counterdie has the die cavity running through counterdie up and down, die cavity is several of rectangular array, a core rod is equipped with in each die cavity, the relative counterdie of core rod can move up and down, whole core rod is fixed on the core rod holder that is positioned at below counterdie, the die work face of the patrix that each die cavity is just right is arranged the boss to lower convexity, boss be arranged at be placed in die cavity light plate fabrication hole directly over to make the boss when mold pressing enter steel plate fabrication hole, the cross section profile of boss is identical with steel plate fabrication hole cross section profile.
The hot-die of the brake block of above-mentioned disk brake, die cavity is nine.
The hot-die of the brake block of above-mentioned disk brake, the height of boss is 2mm.
The hot-die of the brake block of above-mentioned disk brake, boss and patrix are structure as a whole.
Counterdie is arranged multiple die cavity, in each die cavity, configure a core rod, therefore once can the multiple brake block of mold pressing, enhance productivity.The die work face of patrix is arranged the boss to lower convexity, when mold pressing, boss enters in steel plate fabrication hole, friction material is no longer emerged from steel plate fabrication hole, but make friction material lower than the side of steel plate, therefore remove fabrication hole after eliminating mold pressing and to emerge the operation of friction material, reduce the consumption of friction material, because when mold pressing, boss is arranged in steel plate fabrication hole, therefore reduce the pressure differential of friction material pressure that mold pressing makes steel plate fabrication hole place corresponding and other parts friction material, friction material is organized more even, improve the performance of brake pad.

Detailed description of the invention
As shown in Figure 3 and Figure 4, a kind of hot-die of brake block of disk brake, comprises patrix 4, counterdie 7 and core rod 9.Patrix is fixed on upper bolster 6, and the lower surface of patrix is die work face, and die work face is plane.Patrix is cover half, and counterdie is dynamic model.Counterdie has the die cavity 8 running through counterdie up and down, die cavity is several of rectangular array.Be equipped with a core rod 9 in each die cavity, the relative counterdie of core rod can move up and down, and whole core rod is fixed on the core rod holder 10 that is positioned at below counterdie.The die work face of the patrix that each die cavity is just right is arranged the boss 5 to lower convexity, boss be arranged at be placed in die cavity light plate fabrication hole directly over to make the boss when mold pressing enter steel plate fabrication hole, the cross section profile of boss is identical with steel plate fabrication hole cross section profile.
Particularly, die cavity is nine.Preferably, the height of boss is 2mm.Particularly, boss and patrix are structure as a whole.
Counterdie is arranged multiple die cavity, in each die cavity, configure a core rod, therefore once can the multiple brake block of mold pressing, enhance productivity.The die work face of patrix is arranged the boss to lower convexity, when mold pressing, boss enters in steel plate fabrication hole, friction material is no longer emerged from steel plate fabrication hole, but make friction material lower than the side of steel plate, as shown in Figure 5, therefore remove fabrication hole after eliminating mold pressing and to emerge the operation of friction material, reduce the consumption of friction material, because when mold pressing, boss is arranged in steel plate fabrication hole, therefore reduce the pressure differential of friction material pressure that mold pressing makes steel plate fabrication hole place corresponding and other parts friction material, friction material is organized more even, improve the performance of brake pad.
