And upper mold thermal insulation cover 16, in the present embodiment, described cope match-plate pattern 10 has upper mold mounting plate 101 and upper mold
Backing plate 102, mold 11 includes upper mold core 110 and is positioned at the pretension cover 111 that upper mold core is peripheral, certainly, on
Core rod is alternatively referred to as punch.
The upper mold core 110 of mold 11 is fixedly mounted on mold mounting plate 101, at both by screw 12
Between be also clamped with insulating layer material 14, to prevent the heat of mold from being given out, it is achieved mold keep perseverance
The effect of temperature, described pretension cover 111 is arranged on mold mounting plate 101 by screw 12 and spring 13, above-mentioned
Guide pin bushing 15 is fixedly mounted on mold mounting plate 101.
Please in conjunction with shown in Fig. 2, described upper mold core 110 cross section is T-shaped, and be provided with convex body 112, connect convex
Lower surface under the matrix 113 of body, the upper surface being positioned at outside matrix and convex body, the width of this matrix is more than convex
The width of body, this upper mold core 110 has and runs through the several installing holes 114 inserted for heating rod upper surface and pass through
Wearing the storage hole 115 of end face, described pretension cover 111 is provided with accepting groove 116 and is positioned at the side of accepting groove periphery
Wall 117, described accepting groove 116 is contained in the convex body 112 of upper mold core 110, and described matrix 113 is barred from receipts
The outside of tank, and sidewall 117 be provided with for heating rod install several installing holes 118.
Referring again to shown in Fig. 1, described lower mold include lower bolster 20, lower mold 21, lower mold thermal insulation cover 22,
A pair guide pillar 23, insulating layer material 24 and several mould emptier 25, in the present embodiment, this lower bolster has
There are lower mold backing plate 201 and the lower mold mounting plate 202 fixing with lower mold backing plate, in this lower mold backing plate 201 and lower mold
Insulating layer material 24 it is provided with between installing plate 202；Described lower mold 21 has releasable die 210, first time
Core rod 211 and the second lower mold core 212, the first lower mold core is easy to molding wheel rim centre bore, in the present embodiment,
This releasable die 210 is four half modules diagonally moved.
Wherein, the second lower mold core 212 is fixedly mounted on lower mold mounting plate 202, and the first lower mold core 211 is fixed
Being arranged in the second lower mold core 212, guide pillar 23 is fixedly mounted on lower mold mounting plate 202 by interference fit,
And the guide pin bushing 15 of this guide pillar 23 and upper mold cooperates, guiding the up and down motion of upper and lower mould, described lower mold is protected
Temperature cover 22 is fixedly mounted on releasable die 210.
Referring again to shown in Fig. 1 and Fig. 3, described mould emptier 25 has baffle plate 251, is positioned at baffle plate side
Hydraulic cylinder 252, one end connect hydraulic cylinder and the pull bar 253 of other end connection releasable die；At the bottom of each die
Portion is provided with slider guide 213, has guide runner 204 at lower mold mounting plate correspondence slider guide.When the demoulding, hydraulic pressure
Cylinder 252 for stopping surface and pulls pull bar 253 with baffle plate outwardly, makes pull bar 253 drive die 210 at guide runner
Move on 204, thus, motion the most mutually removed by releasable die 210, by wheel rim break away from moulds；
Certainly, after the demoulding, during to Guan Bi releasable die next product of molding again, in the same way,
By hydraulic cylinder 252, releasable die 210 being urged to closure state, thus, aspect shaped article departs from mould
Tool.
Generally at stock (such as light-alloy wheel rim) before forging, need to be heated to stock more than 450 degree,
Then, stock is transported in mould, because, in prior art, having thermal losses when stock is in carrying,
And the present invention by mold be provided with for heating rod insert installing hole, i.e. present embodiment be by
Upper mold core 110 is provided with several installing hole inserted for heating rod, and also can be provided with for heating rod on pretension cover 112
The several installing holes inserted, to heat mould, it is ensured that the heat temperature constant state of mold, quilt simultaneously
The mold of heating transfers heat to stock, with heating further to stock, and pacifies in the outside of mould
Equipped with thermal insulation cover, prevent heat from outwards distributing, it is provided that the mould state of a kind of constant temperature is forged.
Certainly, the present invention is not only provided with the installing hole of heating rod in mold, it is possible in lower mold
This heating rod is installed, or in lower mold, converts a kind of transcalent material, and without installing heating rod,
So the heat conductivity of lower mold is more than the heat conductivity of mold.
A kind of integral light-weight alloy wheel rim isothermal forging mould disclosed by the invention, disposably will be possible not only to
Blank forging becomes wheel loop-shaped, it is also possible to directly make centre bore and spoke in the forging process of wheel rim, and
In whole forging process, blank temperature is identical with the temperature of upper and lower mould, therefore, has given full play to blank
Plasticity, forging wheel rim allowance out is little, dimensional accuracy is high and mechanical property good, improves material
Utilization rate, reduces the production cost of wheel rim, can be widely used in the production of all size light alloy wheel circle；
It is designed to rim of vehicle wheel structure be suitable for the structure that isothermal forging requires, blank can be reduced when shaping
Big forming pressure, reduces the requirement for equipment tonnage, and the design of releasable die is easy to what gripping had shaped
Forging, is also beneficial to the cleaning of mould, repairs and change, improve the mold use life-span, reduce simultaneously
The maintenance cost of mould.
