[0026] According to the above structure, the blow gas import, steam import and cooling liquid import of lower mould base 1 and upper mould base 3 can be connected to external energy supply unit through pipeline respectively, and the energy supply unit is used for circulating flow injection work of high-pressure air, high-temperature steam and low-temperature cooling liquid;

[0027] That is, high-temperature steam can be used for high-temperature steam heating treatment of lower mould base 1 and upper mould base 3, so as to provide necessary high-temperature conditions for hot press forming of sole;

[0028] And high-pressure gas can blow out high-temperature steam in the inside when cold and hot conversion, so as to reduce the high-temperature steam residue in inner runner 7 and improve the cooling speed of subsequent cooling;

[0029] Low-temperature liquid injection can be used for quick water cooling treatment of lower mould base 1 and upper mould base 3, so that in actual use, through the cooperation of lower mould base 1 and upper mould base 3, the cooling forming speed of sole after hot press forming can be effectively improved, and the active water cooling use effect is obtained, the cooling forming efficiency of sole is greatly improved, so that the overall production speed of sole can be greatly improved, and batch quick production work is suitable.

[0030] In this embodiment, in order to heat insulation treatment of the upper and lower die holder, the lower die holder 1 is fixedly installed with a lower heat insulation plate 2, and the lower surface of the upper die holder 3 is fixedly installed with an upper heat insulation plate 4. The heat insulation plate 702 can play a certain heat insulation effect on the two die holders, avoiding the direct transmission of the high temperature effect of the die holder to the forming mold of the sole, preventing the high temperature of the die holder from causing overheating damage to the sole, improving the forming effect of the sole, having certain heat insulation and cooling use characteristics, and having certain overheating forming protection performance.

[0031] In this embodiment, in order to facilitate the installation of the upper die holder 3 of the utility model on the external driving cylinder body, a die holder fixing disc 5 is fixedly installed at the center position of the upper surface of the upper die holder 3, and a plurality of fixing holes are formed in the die holder fixing disc 5. The die holder fixing disc 5 can conveniently connect the driving cylinder body of the external hot press to drive the upper die holder 3 to descend

[0032] In order to improve the displacement guiding property, guide hole grooves 6 are arranged on the both sides of the die holder fixing disc 5 and located on the upper surface of the upper die holder 3. The guide hole grooves 6 can be used for installing linear guide columns. The guide columns are limitingly and slidably connected with the external hot press structure, so as to provide the upper and lower displacement effect of the upper die holder 3 with certain displacement guiding property.

[0033] Working principle: when the cooling hot-pressing die holder is used, the lower die holder 1 can be installed on the lower workbench of the hot press, and the upper die holder 3 can be installed on the lower pressing driving cylinder body of the hot press. The driving cylinder body can drive the upper die holder 3 to ascend and descend.

[0034] Meanwhile, the air inlet, steam inlet and cooling liquid inlet of the lower die holder 1 and the upper die holder 3 can be respectively connected with the external energy supply unit through pipelines. The energy supply unit is used for circulating and flowing injection of high-pressure air, high-temperature steam and low-temperature cooling liquid. The flowing gas and liquid can be discharged from the corresponding outlet.

[0035] When the sole is hot-pressed and formed, the forming mold lower die of the sole can be fixed on the lower die holder 1, and the upper die of the sole hot-pressing and forming can be fixed on the lower surface of the upper die holder 3.

[0036] When forming, the production raw material of the sole is injected into the lower die cavity of the forming mold. After injection is completed, the matched hot press machine is started, and the driving cylinder body of the hot press can work. When the driving cylinder body works, the output rod of the driving cylinder body extends. The extended output rod can drive the upper die holder 3 to descend, so that the upper die of the forming mold can be driven to descend by the descending upper die holder 3, thereby completing the die closing work between the upper die and the lower die of the forming mold.

[0037] After the mold is closed, high-pressure steam is supplied through an external steam set, and the high-temperature steam is injected into the inner flow channel 7 of the lower mold base 1 and the upper mold base 3 through the lower steam inlet 103 and the upper steam inlet 303, respectively, and the continuously injected high-temperature steam can be circulated and discharged through the lower steam outlet 104 and the upper steam outlet 304.

[0038] The high-temperature steam that enters through circulation can heat the lower mold base 1 and the upper mold base 3, and the heated lower mold base 1 and the upper mold base 3 can guide heat to the forming mold of the sole, thereby completing the hot pressing of the sole.

[0039] When cooling and forming after hot pressing are required, high-pressure air is injected into the lower mold base 1 and the upper mold base 3 through a high-pressure air pump, and is discharged through the corresponding air outlet, so that the high-temperature steam in the flow channel of the lower mold base 1 and the upper mold base 3 can be blown out by the high-pressure air, thereby avoiding the residual high-temperature steam in the mold base and improving the subsequent cooling rate.

[0040] After the high-temperature steam is blown out, the low-temperature cooling liquid formed by the cooling set can enter the inside of the lower mold base 1 and the upper mold base 3 through the pipeline, so that the flowing low-temperature cooling liquid can effectively cool and cool the lower mold base 1 and the upper mold base 3, thereby accelerating the cooling and forming efficiency of the sole in the mold.

[0041] The inner flow channel 7 can cooperate with the external energy supply set to circulate the high-temperature steam and the cooling liquid, thereby achieving rapid heating and cooling of the lower mold base 1 and the upper mold base 3, and the rapid heating and cooling of the lower mold base 1 and the upper mold base 3 can be conducted to the forming mold of the sole, thereby completing the rapid cooling and heating of the forming mold of the sole, and thereby effectively improving the hot pressing production and cooling and forming efficiency of the sole.

[0042] In actual use, the sole can be heated by high-temperature steam, steam can be blown out, and water cooling and heat exchange can be used for cooling during production and forming, which can effectively improve the cooling and forming speed of the sole after hot pressing, has an active water cooling effect, compared with the traditional natural cooling and forming, the cooling and forming efficiency of the sole can be greatly improved, thereby effectively improving the overall production speed of the sole, and is suitable for batch production of the sole, and has higher production efficiency.

[0043] Meanwhile, the lower die seat 1 and the upper die seat 3 of the utility model all adopt independent pipelines and flow channels to carry out heating and cooling treatment, and the two are independently structured in a split cavity type, so that the heating and cooling use effects of the double-cavity independent type are achieved when in use, heating or cooling work between the two die seats can be synchronously carried out, the synchronous cooling and heating speed of the two die seats can be effectively improved, the cooling and heating speed of the utility model is faster, the production speed is effectively improved, and the practicality is stronger.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, the scope of the utility model is defined by the appended claims instead of the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims should be included in the utility model.
