Preferably, the base is provided with a recovery device for recovering the cooling liquid, the recovery device comprises a filter for filtering impurities in the cooling liquid and a condenser for reducing the temperature of the cooling liquid, and the recovery device is communicated with the spray pipe to form the circulation use of the cooling liquid.
Preferably, the part upsetting device is further provided with a first fire tongs used for placing the part on the lower die and a second fire tongs used for taking away the part after upsetting, the clamping ends of the first fire tongs are two semi-circular arcs which are oppositely arranged, and the clamping ends of the second fire tongs are two planes which are oppositely arranged.
The utility model has the beneficial effects that: during operation, the work piece that will not upset is placed on the lower mould, then the starter motor, makes the upper die group take the mould to move down along the guide rail to with the work piece upset, then take away the work piece, at whole in-process, the nozzle is the cool cooling liquid of spouting that does not stop, thereby guarantees that the temperature of upper and lower mould can not be too high, prevents that the upper and lower mould from producing the deformation because of the temperature, and then the life of extension upper and lower mould, reduce cost.

Detailed Description
The utility model will be further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in figures 1-4, the upsetting device for the synchronizer gear sleeve blank mainly comprises a base 1, an upper die set 2, an upper die 4, a lower die 3, a side support frame 5 and a spray pipe 7. Wherein upwards be provided with lower mould 3 in the middle part of base 1 top surface, upwards be provided with mould 4 at the middle part of last module 2 bottom surface, and go up mould 4 and the corresponding setting of lower mould 3, this is prior art, and no longer repeated here.
All be provided with the collateral branch strut frame 5 that is used for supporting last moulding-die group 2 in the left and right sides of base 1, all be provided with guide rail 6 on the medial surface of two collateral branch strut frames 5, be provided with on the left and right sides face of going up moulding-die group 2 with guide rail 6 assorted spout, it is used for driving the motor that moulding-die group 2 reciprocated along guide rail 6 to be provided with in 2, be provided with the spray tube 7 towards last mould 4 on going up moulding-die group 2, be provided with the coolant liquid that is used for cooling to go up mould 4 and lower mould 3 in the spray tube 7, preferably, adopt graphite alkene coolant liquid.
In order to prevent the coolant from flowing around, baffles are provided on the front and rear sides of the base 1 to collect the coolant on the base 1 and allow the coolant to flow into the coolant recovery tank. Be provided with the recovery unit who is used for retrieving the coolant liquid simultaneously on base 1, recovery unit includes coolant liquid recovery pond, be arranged in filtering coolant liquid impurity filter 8 and be used for reducing the condenser 9 of coolant liquid temperature, coolant liquid recovery pond, filter 8 and condenser 9 connect gradually through the pipeline, recovery unit and spray tube 7 intercommunication form the used circulation of coolant liquid, can effectively prevent the waste of coolant liquid.
