Polyurethane insoles are relatively soft and have good cushioning, making them suitable for long periods of walking or exercise. EVA insoles are relatively hard and can effectively support the arch of the foot, making them suitable for long periods of standing or walking. Rubber insoles have anti-slip and wear-resistant properties, making them suitable for outdoor sports or special work environments. Currently, the foaming equipment used for insole processing is a device that injects foaming raw materials into a mold and shapes the foam to form the insole.

[0003] However, current foaming equipment lacks the function of cooling the foamed material during the actual foaming process, which prevents the insoles from cooling quickly during foaming, thus affecting the actual processing efficiency. Furthermore, uneven cooling rates are also prone to occur, resulting in inconsistent cooling levels of the insoles and affecting the foaming quality of the insoles. Utility Model Content

[0004] This invention provides a high-efficiency foaming device for insole processing, which effectively solves the problems mentioned in the background art. Current foaming equipment lacks a cooling function for the insole foaming material during actual foaming processing, resulting in insufficient cooling of the insole during foaming, thus affecting the actual processing efficiency. Furthermore, uneven cooling rates are also prone to occur, leading to inconsistent cooling levels and affecting the foaming quality of the insole.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency foaming equipment for shoe insole processing, comprising a mold base, a lower molding mold connected to the top of the mold base, an upper molding mold disposed above the top of the lower molding mold, guide posts disposed at the top corners of the mold base, the corners of the upper molding mold being guided and slidably connected to the guide posts via limiting seats, a top plate fixedly connected to the top of the guide posts, a hydraulic cylinder fixedly installed at the top center of the top of the top plate, foaming mold grooves uniformly opened on the top surface of the lower molding mold, and a molding punch disposed on the bottom surface of the upper molding mold corresponding to the foaming mold grooves;

[0007] One side of the lower forming mold is connected to a liquid inlet pipe, and the other side of the lower forming mold is connected to a liquid return pipe. The liquid inlet end of the liquid inlet pipe is connected to a booster pump, which is powered by an external power source. The mold base has a liquid storage chamber inside, and both sides of the mold base have heat dissipation grooves. Heat dissipation metal plates are evenly arranged on the inner side of the heat dissipation grooves.

[0008] Preferably, the telescopic end of the hydraulic cylinder is fixedly connected to the top of the upper forming mold, and the hydraulic cylinder drives the upper forming mold to move up and down along the guide post. Injection joints are provided on both sides of the top of the upper forming mold.

[0009] Preferably, multiple sets of the misaligned barrier plates are provided, and the lengths of two adjacent misaligned barrier plates are equal, and the heat-conducting base plate is in close contact with the top wall of the heat dissipation cavity.

[0010] Preferably, the liquid storage chamber is filled with coolant, and the booster pump guides the coolant from the liquid storage chamber to the heat dissipation cavity.

[0011] Preferably, an intercepting arc plate is installed on the edge of the upper forming mold, and air collecting grooves are equidistantly opened on the inner side of the intercepting arc plate. A processing box is installed on the edge of the upper forming mold at the top position of the intercepting arc plate.

[0013] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0014] 1. The coolant in the storage chamber is conveniently guided to the heat dissipation cavity in the lower mold through the inlet pipe, return pipe, and booster pump. By setting staggered baffles and heat-conducting base plates inside the lower mold, the heat generated during the foaming of the insole in the foaming mold groove can be quickly transferred to the heat dissipation cavity. The coolant can then quickly absorb the heat, achieving uniform and timely heat dissipation and improving the molding speed of the insole. At the same time, the multiple sets of staggered baffles in the heat dissipation cavity can effectively slow down the flow rate of the coolant in the heat dissipation cavity, making it easier for the coolant to more thoroughly remove the heat from the heat-conducting base plate and achieve thorough heat dissipation.

[0015] In addition, the combination of heat dissipation grooves and heat dissipation metal plates allows for the collection of heat carried by the coolant in the reservoir chamber, facilitating the dissipation of heat accumulated in the coolant and promoting subsequent circulation and heat dissipation of the coolant, thereby improving the efficiency and quality of the foaming and molding of the insole.

[0016] 2. By setting intercepting arc plates and gas collecting grooves on the edge of the upper molding die, the gas emitted between the upper and lower molding dies can be intercepted. In conjunction with the gas collecting fan inside the processing box, the gas is quickly collected into the processing box through the gas collecting groove. This prevents the gas generated after the insole foaming process from overflowing. The filter screen on the top of the processing box facilitates gas filtration, preventing direct gas discharge that could cause odor and pollution, thus protecting the workshop environment. At the same time, the filter screen is snapped into the fitting groove for easy replacement and cleaning. Attached Figure Description

[0026] Example: Figure 1-5 As shown, this utility model provides a technical solution: a high-efficiency foaming equipment for shoe insole processing, including a mold base 1, a lower molding mold 2 connected to the top of the mold base 1, an upper molding mold 3 disposed above the top of the lower molding mold 2, guide posts 4 disposed at the top corners of the mold base 1, and the upper molding mold 3 being guided and slidably connected to the guide posts 4 at the corners via limiting seats 5, a top plate 6 fixedly connected to the top of the guide posts 4, a hydraulic cylinder 7 fixedly installed at the top center of the top of the top plate 6, foaming mold grooves 8 evenly opened on the top surface of the lower molding mold 2, and a molding punch 9 disposed on the bottom surface of the upper molding mold 3 corresponding to the foaming mold grooves 8, the telescopic end of the hydraulic cylinder 7 being fixedly connected to the top of the upper molding mold 3, and the hydraulic cylinder 7 driving the upper molding mold 3 to move up and down along the guide posts 4, and injection joints disposed on both sides of the top of the upper molding mold 3 to facilitate the mold closing between the lower molding mold 2 and the upper molding mold 3, and to facilitate the introduction of foaming material between the foaming mold grooves 8 and the molding punch 9;

[0027] The lower mold 2 has a heat dissipation cavity 10 inside, and the heat dissipation cavity 10 is connected with staggered baffles 11 at equal intervals. A heat-conducting base plate 12 is provided on the top of the staggered baffles 11. There are multiple sets of staggered baffles 11, and the lengths of two adjacent staggered baffles 11 are equal. The heat-conducting base plate 12 is in close contact with the top wall of the heat dissipation cavity 10, so that the heat during the foaming of the insole in the foaming mold 8 can be quickly transferred into the heat dissipation cavity 10.

[0028] A liquid inlet pipe 13 is connected to one side of the lower mold 2, and a liquid return pipe 14 is connected to the other side of the lower mold 2. A booster pump 15 is connected to the liquid inlet end of the liquid inlet pipe 13. The booster pump 15 is powered by an external power source. A liquid storage chamber 16 is provided inside the mold base 1. Coolant is provided inside the liquid storage chamber 16. The booster pump 15 guides the coolant in the liquid storage chamber 16 to the heat dissipation cavity 10, so that the coolant can quickly absorb heat and achieve uniform and timely heat dissipation treatment, which improves the molding speed of the insole. Heat dissipation grooves 17 are provided on both sides of the mold base 1. Heat dissipation metal plates 18 are evenly arranged on the inner side of the heat dissipation grooves 17.

[0029] An intercepting arc plate 19 is installed on the edge of the upper forming mold 3. An air collecting groove 20 is equidistantly opened on the inner side of the intercepting arc plate 19. A processing box 21 is installed on the edge of the upper forming mold 3 at the top position of the intercepting arc plate 19. An air collecting fan 22 is equidistantly installed on the bottom inner side of the processing box 21. The air collecting fan 22 is powered by an external power source. A fitting groove 23 is opened on the top edge of the processing box 21. A filter screen 24 is embedded and fitted on the inner side of the fitting groove 23. The air collecting groove 20 and the bottom of the processing box 21 are connected by an air supply pipe. The filter screen 24 is an activated carbon filter screen. A sealing strip is provided at the connection between the edge of the filter screen 24 and the fitting groove 23. When the upper forming mold 3 and the lower forming mold 2 are separated, the gas emitted between them can be intercepted and collected into the processing box 21 to ensure the tightness of the connection between the edge of the filter screen 24 and the fitting groove 23.

[0030] The working principle and usage process of this utility model: In the actual application process, the high-efficiency foaming equipment for insole processing firstly drives the upper mold 3 to move up and down through the hydraulic cylinder 7. With the help of the guide column 4 and the limit seat 5, the upper mold 3 is stably covered on the top of the lower mold 2 to achieve mold closing. After the lower mold 2 and the upper mold 3 are combined, the positions of the molding punch 9 and the foaming mold groove 8 are corresponding. Then, the foaming material is poured into the injection joints set on both sides of the top of the upper mold 3, and the foaming material is introduced into the foaming mold groove 8 and the molding punch 9 through the injection joints.

[0031] During the foaming and molding process of the foamed material, the coolant in the storage chamber 16 is conveniently guided to the heat dissipation cavity 10 in the lower mold 2 through the liquid inlet pipe 13, the liquid return pipe 14, and the booster pump 15. Furthermore, by setting the staggered baffle plate 11 and the heat-conducting base plate 12 inside the lower mold 2, the heat generated during the foaming and molding of the insole in the foaming mold 8 can be quickly introduced into the heat dissipation cavity 10, thereby using the coolant to quickly absorb the heat, achieving uniform and timely heat dissipation treatment, and improving the molding speed of the insole.

[0032] Furthermore, during the flow of coolant within the heat dissipation cavity 10, the multiple sets of staggered baffles 11 within the heat dissipation cavity 10 can effectively slow down the flow speed of coolant within the heat dissipation cavity 10, thereby facilitating the coolant to more thoroughly remove heat from the heat-conducting base plate 12 and achieve thorough heat dissipation. Moreover, after the coolant has undergone heat dissipation treatment, when it flows back to the storage chamber 16 through the return pipe 14, the heat dissipation side groove 17 and heat dissipation metal sheet 18 on the side of the mold base 1 can dissipate the heat accumulated in the coolant after it has carried heat and collected it in the storage chamber 16, facilitating the subsequent circulation and heat dissipation of the coolant.

[0033] After the foamed material is formed, the upper mold 3 is moved upward by the hydraulic cylinder 7, so that the upper mold 3 is separated from the lower mold 2. During this process, by setting the intercepting arc plate 19 and the gas collecting groove 20 on the edge of the upper mold 3, the gas emitted between the upper mold 3 and the lower mold 2 can be intercepted. In conjunction with the gas collecting fan 22 inside the processing box 21, the gas is quickly collected into the processing box 21 through the gas collecting groove 20, so that the gas generated after the insole foaming is not overflowed.

[0034] Furthermore, after the gas is collected inside the treatment box 21, the filter 24 on the top of the treatment box 21 can be used to filter the gas, avoiding direct discharge of gas that may cause odor and pollution, thus protecting the workshop environment. The filter 24 is an activated carbon filter, which ensures its filtration effect. At the same time, the filter 24 is snapped into the fitting groove 23, which makes it easy to replace and clean the filter 24 later.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
