Description
Technical field
Field of brake pad is the utility model is related to, is more particularly to a kind of brake block hot pressing die.
Background technology
At present, the main moulding process of brake block is molded by mould heat pressure, and wherein mould includes upper external mold, lower outer
The disk body of brake block, in shaping, is fixedly clamped, in brake block by mould, upper internal model and core insert by upper internal model and core insert
Disk body two sides put on the raw material of friction material, be then finally putting into hot press on the outside of raw material with external mold and lower outer die casing
Interior progress is hot-forming, but in practical operation, due to raw material, density small size is big before non-hot pressing, upper external mold and lower external mold
Fail that raw material is fully sealed, raw material is revealed from the gap location of upper external mold and lower external mold sometimes in hot pressing, after causing shaping
Quality of brake pad is unqualified.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of brake block hot pressing die for avoiding raw material from revealing.
To achieve the above object, the utility model provides following technical solution：A kind of brake block hot pressing die, including it is upper
External mold, lower external mold, upper internal model and core insert, the one side of upper external mold towards the lower external mold offer the axis of axis and upper external mold
Consistent annular groove, the one side of the lower external mold towards upper external mold are equipped with the first ring side being slidably matched with annular groove, the upper external mold
Be equipped with the second ring side towards the one side of lower external mold, second ring while inner wall be bonded with outer wall during the first ring.
The axis threaded hole consistent with the axis of upper internal model, institute are offered on the further upper internal model and core insert
State and fixing screws are equipped with threaded hole, the core insert offers the ailhead for accommodating fixing screws away from one end of upper internal model
Holding tank.
The further upper internal model offers the locating slot of bar shaped away from one end of core insert, is equipped with the locating slot
Positioning strip.
The depth of the further annular groove is 10mm-20mm.
In conclusion the utility model will not be revealed in the whole forming process raw material ring of brake block, it is ensured that molding brake
The quality of car piece.

Embodiment
A kind of embodiment of brake block hot pressing die of the utility model is described further referring to figs. 1 to Fig. 3.
A kind of brake block hot pressing die, including upper external mold 1, lower external mold 2, upper internal model 3 and core insert 4, upper 1 court of external mold
The one side of downward external mold 2 offers the axis annular groove consistent with the axis of upper external mold 1, and the lower external mold 2 is towards the one of upper external mold 1
Face is equipped with the first ring side 8 being slidably matched with annular groove, and the one side of the upper external mold 1 towards lower external mold 2 is equipped with the second ring side 9, institute
The inner wall that the second ring is stated while 9 is bonded with during the first ring 8 outer wall.
When brake block hot pressing is carried out, as shown in Figure 1, the disk body 5 of brake block is inserted into the groove of core insert 4 first
It is interior, it is necessary to explanation be that to have the groove of positioning tooth and core insert 4 coordinated with positioning tooth on the inner wall of disk body 5, it is ensured that disk
Body 5 will not rotate in the axial direction in hot pressing, and then upper internal model 3 is fastened on disk body 5, the raw material ring on set on disk body 5,
Internal model 3 and core insert 4 in upset, upper internal model 3, is then inserted into upper external mold 1 by the raw material ring on the opposite side of disk body 5 also covers,
Finally lower external mold 2 is sleeved on core insert 4 and the first ring side 8 of lower external mold 2 is inserted into the annular groove of upper external mold 1, and is made
Second ring of external mold 1 while 9 with the first ring while 8 be bonded, it is ensured that raw material ring be when being extruded be fully sealed upper external mold 1 and under
In the cavity that external mold 2 is formed, it is finally putting into hot-forming in hot press, the first ring side 8 is gradually pressed into ring in forming process
In groove, whole forming process raw material ring will not be revealed, it is ensured that the quality of molding brake block.
It is consistent with the axis of upper internal model 3 that axis is offered in the preferable upper internal model 3 of the present embodiment and core insert 4
Threaded hole, the threaded hole is interior to be equipped with fixing screws 6, and the core insert 4 offers solid for accommodating away from one end of upper internal model 3
Determine the holding tank of the ailhead of screw 6, when internal model on installing 3, core insert 4 and disk body 5, fixing screws 6 can be screwed into,
Internal model 3 and core insert 4 in connection, and upper disk body 5 between internal model 3 and core insert 4 is clamped, internal model 3 is with so in upset
It would not be separated when internal model 4.
The preferable upper internal model 3 of the present embodiment offers the locating slot of bar shaped, the positioning away from one end of core insert 4
Being equipped with positioning strip 7 in groove, the positioning strip 7 in the present embodiment is integrally fixed on desktop, mould external skin temperatures height during due to hot pressing,
Operator needs to take adiabatic gloves work, when fixing screws 6 are rotated, easily skids, therefore when mounted first will be upper
Internal model 3 is directed at the insertion positioning of positioning strip 7, and upper internal model 3 is positioned, then installs core insert 4 and disk body 5, rotates fixing screws 6 at this time
Internal model 3 would not be driven to rotate, so as to play stabilization, without by living in internal model 3.
The depth of the preferable annular groove of the present embodiment is 10mm-20mm, it is ensured that there is annular groove enough depth to make first
Ring side 8 is completely slipped into annular groove.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
