Specific embodiment
As depicted in figs. 1 and 2, the hot-forming closed die of a kind of circulation formula drum-type brake pad isodensity of the utility model, Including upper die and lower die.Upper mold is by 8 structure of punch-pin 5, punch-pin link block 7 and upper mounting plate that is connected in turn from bottom to top Into punch-pin 5 is connected to the bottom of punch-pin link block 7, and the top of punch-pin link block 7 is connected with upper mounting plate 8.Upper mounting plate 5 is used It is fixed in by entire upper mold on press.The cross-sectional profile of punch-pin link block 7 is dimensioned slightly smaller than the cross-sectional profile ruler of punch-pin 5 Very little, the cross-sectional profile size of punch-pin 5 is consistent with the inner profile size of interior lining panel 6.When upper mold coordinates with lower die, punch-pin 5 exists Gapless is free to slide in interior lining panel 6, and there are gap between punch-pin link block 7 and interior lining panel 6, so can be to avoid suppressing Journey convex mould link block 7 is worn.
Lower die is made of mold core 2, die cavity 3, interior lining panel 6 and lower baffle plate 1, and interior lining panel 6 is arranged in die cavity 3, die cavity 3 and interior The bottom of liner plate 6 is both connected on lower baffle plate 1, and interior lining panel 6 is higher than die cavity 3, and mold core 2 is sleeved in interior lining panel 6 and falls in lower block On plate 1.Mold core 2 is more than the boss structure of bottom periphery for top peripheral, and top is embedded in interior lining panel 6, matches somebody with somebody with interior lining panel 6 It closes, is slided up and down in the space that can be surrounded in interior lining panel 6;Lower clan on lower baffle plate 1, by lower baffle plate 1 limit mold core 2 to Under position.Lower baffle plate 1 (height of lower part is slightly larger than the thickness of lower baffle plate 1) is stretched out in 2 lower part of mold core, can so ensure to suppress Cheng Zhong, lower baffle plate 1 do not stress.During the demoulding, mold core 2 is released by stripping tank 9 (stripper apparatus), but mold core 2 and stripping tank 9 are simultaneously It is not attached to together, entire mold is fixed on demoulding station with production line, stripper apparatus.
The punch-pin underside shape is identical with product upper surface radian, mold core upper surface shape and product lower surface Radian is identical, and punch-pin is designed with four side contour dimension of mold core according to product contour dimension.
Interior lining panel 6 is surrounded by four pieces of side plates (two block length side plates and two blocks of short side plates), and four pieces of side plates are each attached to lower baffle plate 1 On.
3 exterior design of die cavity has clamping pin hole 11, and clamping jaw (being not drawn into figure), clamping jaw are provided on the device of carrying mould Both sides are respectively there are two axis pin, and when mold operates in the production line to be needed to carry, the axis pin insertion on clamping jaw is clamped in pin hole 11, Ensure that mold transport process is reliable.The outside of die cavity 3 is also devised with stripping chute 10, for fixing die cavity 3 during the demoulding, prevents from demoulding In the process, frictional force is excessive causes entire lower die to be taken up.
Upper mold is fixed on by upper mounting plate 8 on hot press, under lower baffle plate 1, mold core 2, die cavity 3 and interior lining panel 6 form Mould is used in turn with production line.The appearance and size of mold is fixed, and is remained unchanged, and remodeling only need to be as the brake required by product type Plate shape changes the size of mold core 2, punch-pin 5 and interior lining panel 6, is transformed convenient for mold.
Only punch-pin 5, mold core 2 and interior lining panel 6 bear frictional force during mold use, and long-time service generates abrasion Afterwards, punch-pin 5, mold core 2 and interior lining panel 6 are only needed to change, can effectively extend die life, saves cost, convenient for safeguarding.
A kind of course of work of the hot-forming closed die of above-mentioned circulation formula drum-type brake pad isodensity is as described below:
It is filled in the space surrounded in interior lining panel 6 with mold core 2 after mixing loose object material, it is by manipulator that entire lower die is defeated It is sent on the workbench of hot press, starts to suppress, the space that punch-pin 5 surrounds under hot press drive into interior lining panel 6, entire mould Tool forms a closed die.The compaction of the material under the action of hot press of punch-pin 5, is finally protected after hot pressing several times and exhaust cycle Pressure completes pressing process.After the completion of compacting, punch-pin 5 is lifted with hot press.Such as Fig. 3, during the demoulding, lower die is delivered to stripping tank 9 Top, the piston rod of stripping tank 9 stretch out, and mold core 2 with the molded blank part 4 suppressed is released, completes the demoulding.After completing the demoulding, Mold core 2 resets, and flow is suppressed into next round.
