Detailed Description of the Preferred Embodiments

[0023] The following will detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0024] As Figures 1-4As shown in the figure, the sole mold structure capable of externally connecting to blowing-assisted demolding provided in this embodiment includes a fixed base 1. Symmetric lower mold grooves 2 are provided on the upper surface of the fixed base 1. Blowing demolding structures 3 are symmetrically arranged on the lower surface of the fixed base 1. The blowing demolding structure 3 includes a number of hollow sealing sleeves 4, a sealed demolding air core 6 slidably installed through the fixed base 1 to the lower mold groove 2, an electric telescopic rod 5 provided on the lower surface of the sealed demolding air core 6, a shunt air pipe 7 connected to the outside of the hollow sealing sleeve 4, a confluence air pipe 8 connected to the ends of a number of shunt air pipes 7, and a number of air inlet pipes 9 provided on the outside of the confluence air pipe 8. Upper mold protrusions 10 are symmetrically arranged above the lower mold groove 2. The fixed base 1 facilitates the opening of the lower mold groove 2 on its upper surface. The lower mold groove 2 and the upper mold protrusion 10 facilitate heating and injecting the injection molding raw material into the required sole shape by extrusion. The blowing demolding structure 3 facilitates blowing demolding of the sole body after injection molding. The hollow sealing sleeve 4 facilitates accommodating and supporting the electric telescopic rod 5 and connecting the shunt air pipe 7 at the same time. The electric telescopic rod 5 facilitates controlling the up and down movement of the sealed demolding air core 6, so that the sealed demolding air core 6 seals the lower bottom surface of the lower mold groove 2. The sealed demolding air core 6 facilitates keeping the lower bottom surface of the lower mold groove 2 in a closed state during injection molding. After injection molding is completed, the sealed demolding air core 6 moves downward, so that gas enters the lower mold groove 2 from the hole removed by the sealed demolding air core 6 and blows up and demolds the sole body completed by injection molding therein. The shunt air pipe 7 facilitates connecting the hollow sealing sleeve 4 and the confluence air pipe 8, so that the compressed gas in the confluence air pipe 8 enters the hollow sealing sleeve 4. The confluence air pipe 8 facilitates evenly entering the compressed gas entering from the air inlet pipe 9 into each shunt air pipe 7.

[0025] Further, as Figure 1 , Figure 2 , Figure 3 , and Figure 4 shown, the end of the electric telescopic rod 5 is fixedly connected to the upper surface of the inner cavity bottom of the hollow sealing sleeve 4, which facilitates fixedly connecting the electric telescopic rod 5 to the inner cavity of the hollow sealing sleeve 4. A sealed clamping sliding groove 11 adapted to the sealed demolding air core 6 is provided through the lower surface of the fixed base 1 to the upper surface of the lower mold groove 2. The sealed clamping sliding groove 11 facilitates accommodating and clamping the sealed demolding air core 6, so that the lower bottom surface of the lower mold groove 2 is sealed during injection molding. When demolding is required, there are air inlet slots on the lower bottom surface of the lower mold groove 2.

[0026] Further, as Figure 1 , Figure 2 and Figure 3 shown, the confluence air pipe 8 is fixedly connected to the lower surface of the fixed base 1. An electric control valve 12 is provided on the air inlet pipe 9. The electric control valve 12 can cut off the compressed gas entering the confluence air pipe 8 or control the input amount of the compressed gas entering the confluence air pipe 8.

[0027] Further, asFigure 2 As shown in the figure, several transverse grooves 13 are opened on the bottom surface of the lower die groove 2, and several longitudinal grooves 14 are opened on the bottom surface of the lower die groove 2. The transverse grooves 13 facilitate the formation of several anti-slip ridges on the bottom of the injection-molded sole, making the anti-slip effect of the finished shoes better. The longitudinal grooves 14 facilitate the compressed gas entering from the sealed clamping sliding groove 11 to quickly enter all corners of the lower surface of the sole body after injection molding through the gaps, achieving the effect of rapid demolding by blowing.

[0028] Further, as Figure 2 、 Figure 3 、and Figure 4 shown, two upper die protrusions 10 and two lower die grooves 2 are mutually adapted and in corresponding positions, so that they can be completely corresponding and pressed when pressing and injecting the injection molding raw material. A connecting pressing block 15 is arranged on the upper surface of the two upper die protrusions 10, and a fixed connecting plate 16 is arranged on the upper surface of the connecting pressing block 15. The connecting pressing block 15 facilitates the fixed connection of the two upper die protrusions 10, and the fixed connecting plate 16 facilitates the connection and fixation of the connecting pressing block 15.

[0029] Further, as Figure 3 and Figure 4 shown, hydraulic rods 17 are arranged at the end corners of the fixed connecting plate 16. The fixed connecting plate 16 is fixedly connected to the fixed base 1 through the hydraulic rods 17. The hydraulic rods 17 facilitate the pressing or separation of the upper and lower die grooves 2 and the die protrusions 10 through their own expansion and contraction, and also play a role in connection and fixation.

[0030] Further, as Figure 2 、 Figure 3 、and Figure 4 shown, support legs 18 are arranged at the end corners of the lower surface of the fixed base 1, and rubber protection pads 19 are arranged at the ends of the support legs 18. The support legs 18 facilitate the support of the device, and the rubber protection pads 19 prevent the device from sliding due to the ground or damaging the ground during operation.

[0031] Further, as Figure 2 、 Figure 3 、and Figure 4 shown, connecting handling earrings 20 are arranged on the peripheral side surfaces of the fixed base 1. The connecting handling earrings 20 facilitate the handling of the device to different working locations.

[0032] As Figures 1-4As shown in the figure, the principle of the sole mold structure with external blowing assistance for demolding provided in this embodiment is as follows: When the device is in use, the steel cable of the crane should be fixed on the connecting handling earring 20, and then the device is transported to the working location. Then, the compressed gas tank or compressed gas pipeline is fixedly connected to the air inlet pipe 9. When installing the compressed gas tank or compressed gas pipeline, it is necessary to ensure that the electric control valve 12 is in the closed state and the electric telescopic rod 5 is in the extended state. At this time, the sealed demolding air core 6 is tightly engaged in the sealed clamping sliding groove 11, so that there is no notch on the bottom surface of the lower mold groove 2;

[0033] At this time, the operator can put the injection molding raw material into the lower mold groove 2, and then the hydraulic rod 17 will contract, so that the fixed connection plate 16 and the connection pressure block 15 both move downward. At the same time, the upper mold convex block 10 will also move downward until it is engaged with the lower mold groove 2;

[0034] After the injection molding and pressing of the injection molding raw material are completed, the hydraulic rod 17 will extend, so that the fixed connection plate 16 and the connection pressure block 15 both move upward. At the same time, the upper mold convex block 10 will also move upward until it is separated from the lower mold groove 2. Then, the electric telescopic rod 5 contracts, so that the sealed demolding air core 6 disengages from the sealed clamping sliding groove 11 and moves downward with the electric telescopic rod 5. Subsequently, the electric control valve 12 is opened, so that the compressed gas quickly enters the confluence air pipe 8 from the air inlet pipe 9. After that, the compressed gas in the confluence air pipe 8 will quickly and evenly enter the shunt air pipes 7. The compressed gas in the shunt air pipes 7 will enter the hollow sealing sleeve 4, and then enter the lower mold groove 2 through the sealed clamping sliding groove 11. At this time, the compressed gas will move in the gap in the lower mold groove 2, so that the injection molded sole clamped in the lower mold groove 2 can be quickly demolded. After the demolding is completed, the electric control valve is closed, and then the operator takes out the injection molded sole. Subsequently, the electric telescopic rod 5 will extend. At this time, the sealed demolding air core 6 is tightly engaged in the sealed clamping sliding groove 11, so that there is no notch on the bottom surface of the lower mold groove 2, and the next sole injection molding can be carried out.
