The acquisition process does not require creative labor and is a mature existing technology product. This specification will not elaborate on it in detail.

[0021] In this embodiment, the hot pressing forming machine 2 further includes a machine base 5. Above the machine base 5, a bottom mold base 7 is provided. Above the bottom mold base 7, a top mold base 11 is provided. On one side of the front end of the machine base 5, an operation table 12 is provided. Below the bottom mold base 7 and on the upper surface of the machine base 5, an upper sliding rail 6 is fixedly installed. The upper sliding rail 6 is slidably connected to the lower surface of the bottom mold base 7. At the tail end of the upper sliding rail 6, a pushing cylinder 8 is provided. The output rod of the pushing cylinder 8 is fixedly connected to the bottom end of the bottom mold base 7. Thus, by setting the pushing cylinder 8, the bottom mold base 7 can be driven to slide back and forth through its output rod, so as to facilitate the sliding-in feeding and extending discharging of the bottom mold base 7, which has a good feeding and discharging driving use effect.

[0022] In this embodiment, specifically refer to the attached drawings of the specification Figure 5 As shown, the bottom mold base 7 includes a bottom template 701. An upper heat insulation plate 702 is fixedly installed on the upper surface of the bottom template 701. By setting the upper heat insulation plate 702, a certain heat insulation effect can be achieved on the bottom template 701, avoiding the direct transfer of the high-temperature effect of the bottom template 701 to the sole forming mold, preventing the high temperature of the bottom template 701 from causing overheating damage to the sole, and improving the forming effect of the sole, which has a certain heat insulation and cooling use effect; On one side of the back surface of the bottom template 701, there is a lower air blowing inlet 703, and on the other side of the back surface of the bottom template 701, there is a lower air blowing outlet 704. Between the lower air blowing inlet 703 and the lower air blowing outlet 704 and located on the bottom die base 7, there are respectively provided a lower steam inlet 705, a lower steam outlet 706, a lower coolant inlet 707, and a lower coolant outlet 708; Further, the lower air blowing inlet 703, the lower air blowing outlet 704, the lower steam inlet 705, the lower steam outlet 706, the lower coolant inlet 707, and the lower coolant outlet 708 are connected by pipelines to a lower flow dividing valve (not shown in the figure, which is a prior art product), and the lower flow dividing valve is respectively connected by pipelines to a cooling main pipe, a high-temperature steam pipe, and an air blowing main pipe; Furthermore, inside the bottom template 701, there is a lower flow channel for heating and cooling, and the lower flow channel communicates with the outlets of the lower air blowing inlet 703, the lower air blowing outlet 704, the lower steam inlet 705, the lower steam outlet 706, the lower coolant inlet 707, and the lower coolant outlet 708 respectively, that is, the above-mentioned several inlets and outlets share the internal lower flow channel of the bottom template 701; Thus, through the provided lower air blowing inlet 703, lower air blowing outlet 704, lower steam inlet 705, lower steam outlet 706, lower coolant inlet 707, and lower coolant outlet 708, high-temperature steam, low-temperature liquid, and high-pressure gas can enter and be discharged respectively. When the high-temperature steam enters, it can heat the bottom template 701 with high-temperature steam, thereby providing necessary high-temperature conditions for the hot pressing and forming of the shoe sole; And the high-pressure gas can blow out the high-temperature steam inside at high pressure during the heat and cold conversion, thereby reducing the residue of high-temperature steam inside the lower flow channel and enhancing the subsequent cooling and temperature reduction speed; When the low-temperature liquid is injected, it can perform rapid water cooling and temperature reduction treatment on the bottom template 701. Thus, during actual use, it can effectively improve the cooling and forming speed after the hot pressing of the shoe sole, with an active water cooling and temperature reduction effect, greatly enhancing the cooling forming efficiency of the shoe sole, thereby greatly improving the overall production speed of the shoe sole and being suitable for batch and rapid production work.

[0023] In this embodiment, specifically refer to the attached drawings of the specification Figure 6 As shown, similar to the structure of the above-mentioned bottom die base 7, the top die base 11 includes an upper template 1101. On the lower surface of the upper template 1101, an upper heat insulation plate 1108 is fixedly installed. On the outer wall of the back surface of the upper template 1101, there are respectively provided an upper air blowing inlet 1102, an upper air blowing outlet 1103, an upper steam inlet 1104, an upper steam outlet 1105, an upper coolant inlet 1106, and an upper coolant outlet 1107; Further, the upper air injection inlet 1102, the upper air injection outlet 1103, the upper steam inlet 1104, the upper steam outlet 1105, the upper coolant inlet 1106 and the upper coolant outlet 1107 are connected to an upper flow dividing valve through pipelines, and the upper flow dividing valve is respectively connected to the cooling main pipe, the high-temperature steam pipe and the air injection main pipe through pipelines; Among them, an upper flow channel for heating and cooling is arranged inside the upper template 1101, and the upper flow channel communicates with the upper air injection inlet 1102, the upper air injection outlet 1103, the upper steam inlet 1104, the upper steam outlet 1105, the upper coolant inlet 1106 and the upper coolant outlet 1107 respectively, that is, the above-mentioned several upper inlets and outlets share the internal upper flow channel of the upper template 1101; And specifically referring to the attached Figure 7 As shown, the lower flow channel inside the bottom template 701 and the upper flow channel inside the upper template 1101 have the same structure, and the specific structural features of the lower flow channel inside the bottom template 701 are shown in the attached Figure 7 The flow channel adopts a U-shaped structure design to increase the medium contact area; According to the above description, the upper template 1101 of the present invention is used in the same way as the bottom template 701, that is, when high-temperature steam enters, the upper template 1101 can be subjected to high-temperature steam heating treatment, so as to provide necessary high-temperature conditions for the hot pressing and forming of the shoe sole; And high-pressure gas can blow out the high-temperature steam inside under high pressure during the cold and heat conversion, so as to reduce the residual high-temperature steam inside the lower flow channel and improve the subsequent cooling and temperature reduction speed; When low-temperature liquid is injected, the upper template 1101 can be quickly cooled by water, so that in actual use, through the combined use of the upper template 101 and the bottom template 701, the cooling and forming speed after the hot pressing of the shoe sole can be effectively improved, with an active water-cooling temperature reduction effect, greatly improving the cooling forming efficiency of the shoe sole, thereby greatly improving the overall production speed of the shoe sole and being suitable for batch rapid production work.

[0024] In this embodiment, in order to drive the top die holder 11 to perform downward hot pressing treatment, support columns are fixedly installed at the four corners of the upper surface of the machine base 5, an upper fixing plate 9 is fixedly installed between the tops of the four support columns, and a downward pressing cylinder 10 is fixedly installed at the center position of the upper surface of the upper fixing plate 9 through bolts. The output end of the downward pressing cylinder 10 is telescopically connected to a pneumatic rod, and the bottom end of the pneumatic rod is fixedly connected to the upper surface of the top die holder 11; In this way, the downward pressing cylinder 10 can drive the top die holder 11 to perform up and down lifting work through its pneumatic rod, so as to provide a certain displacement driving force for the downward hot pressing and cooling opening and closing of the top die holder 11.

[0025] Working principle: When the present invention performs hot pressing and forming processing on the sole, the lower die of the forming die for the sole can be fixed on the bottom die base 7, and the upper die for hot pressing and forming the sole can be fixed on the lower surface of the top die base 11; During forming, the production raw material of the sole is injected into the lower die cavity of the forming die. After the injection is completed, the machine is started. At this time, the feeding cylinder 8 provided can work. When the feeding cylinder 8 works, it drives the output rod to retract. Thus, through the retraction of the output rod, the bottom die base 7 and the lower die thereon can be driven to move inward, so that the bottom die base 7 can be moved directly below the top die base 11; After the displacement of the bottom die base 7 is completed, at this time, the pressing cylinder 10 provided works. When the pressing cylinder 10 works, it drives its air pressure rod to extend. The extended air pressure rod can drive the top die base 11 to descend. Thus, through the descending top die base 11, the upper die below it can be driven to descend, so that the mold closing work between the upper die and the lower die of the forming die can be completed; After the mold is closed, at this time, the high-pressure steam circulation pump works, and high-temperature steam is continuously injected into the bottom template 701 and the upper template 1101 respectively through the lower steam inlet 705 and the upper steam inlet 1104. The continuously injected high-temperature steam can enter and discharge cyclically through the lower steam outlet 706 and the upper steam outlet 1105; Thus, the high-temperature steam entering through cyclic flow can perform high-temperature steam heating treatment on the bottom template 701 and the upper template 1101. Thus, through the heated bottom template 701 and upper template 1101, heat can be conducted into the mold, so that the hot pressing work on the sole can be completed; When cooling and forming after hot pressing is required, at this time, high-pressure air is injected into the interiors of the bottom template 701 and the upper template 1101 respectively through a high-pressure air pump and discharged through the air blowing outlet. Thus, the high-temperature steam in the two flow channels can be blown out by the high-pressure air, so as to avoid the residue of high-temperature steam inside the template and improve the subsequent cooling rate; After the high-temperature steam is blown out, the low-temperature cooling liquid formed by the cooling unit 4 can enter the interiors of the bottom template 701 and the upper template 1101 respectively through pipelines. Thus, through the flowing low-temperature cooling liquid, effective water-cooling cooling treatment can be performed on the bottom template 701 and the upper template 1101, so as to accelerate the cooling and forming efficiency of the sole in the mold.

[0026] Through the combined use of the above structures, the present invention can enable the sole to have the actual use effects of high-temperature steam heating, steam blowing, and water-cooled heat exchange cooling during production and molding. Compared with traditional sole molding machines, the molding machine of the present invention can perform rapid air blowing and water-cooling cooling operations after hot pressing and molding the sole, effectively improving the cooling and molding speed after hot pressing and molding of the sole, having an active water-cooled cooling use effect. Compared with traditional natural cooling and molding, the present invention can greatly improve the cooling and forming efficiency of the sole, thereby effectively improving the overall production speed of the sole, being suitable for batch rapid production of soles, and having higher production efficiency; At the same time, the bottom template 701 and the upper template 1101 of the present invention both adopt independent pipelines for heat supply and cooling treatment, and the two are designed with a separate chamber independent structure, so as to have a dual-chamber independent heating and cooling use effect during use, and can synchronously perform heating or cooling operations between the two templates. Compared with traditional conduction heating and cooling structures, the present invention does not need to conduct heat or cooling energy through a single heating template, and improves the conduction cooling and heating of traditional templates into a synchronous independent cooling structure. Therefore, the synchronous cooling and heating rates of the two templates can be effectively improved, avoiding the technical problem of slow conduction speed caused by single-template heating and cooling, making the cooling and heating speeds of the present invention faster, effectively improving the production speed, and having stronger practicability; Moreover, the present invention can be assembled and built with multiple units according to actual production and use requirements. A refrigeration and heating supply system is shared among multiple hot pressing and molding machines, so as to have the comprehensive processing use effect of main machine supply and multi-unit production, which can greatly improve the energy supply effect. The units have good series use characteristics, and the number of hot pressing and molding machines can be dynamically increased or decreased according to actual production and use conditions, improving production capacity.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
