Promotion channel by second circulation open height higher than lower cooling annular channel height, the lower cooling circular passage are logical with promotion
The connection position in road leads to close to the connection position of lower cooling circular passage and communication passage, and by lower cooling annular shorter between the two
Road separates.
By using above-mentioned technical proposal, lifting channel is added, the lower cooling circular passage of coolant liquid cycle completely is after a week
It can just be flowed out from lower cooling circular passage, further increase cooling uniformity.
The utility model is further described with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the stereogram of specific embodiment of the present invention；
Fig. 2 is the cooling duct layout viewing of lower mould body in specific embodiment of the present invention.
Specific implementation mode
As shown in Figure 1, the utility model discloses a kind of lower die of hot stamping die, including lower mould body 1, the lower calligraphy or painting model
Body 1 is provided with cavity 11 compatible with shaped article shape is needed, and lower mould body 1 is provided with forming ring 2 around cavity 11, this at
The endoporus of type ring 2 is cavity 11, and forming ring 2 is hard alloy, adds forming ring 2, is carried out to the material near cavity 11 strong
Change, select hard alloy, make it have better hardness, the wear-resisting and characteristics such as heat-resisting, can bear it is indeformable under 800 ° ~ 1000 °,
It avoids the cooling due to heat and cooling water entrained by converted products from causing the deformation of cavity 11, finished product periphery is avoided gradually to become
