[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1-5 As shown, the shoe mold with convenient temperature control in this embodiment includes a lower mold 1, an upper mold 2 and two shoe mold grooves 3 opened on the upper surface of the lower mold 1, the bottom surface of the lower mold 1 is provided with two water grooves 4 corresponding to the two shoe mold grooves 3 respectively, the top wall of the water groove 4 is provided with an annular groove 5, the water groove 4 is located directly below the shoe mold groove 3, and the annular groove 5 is located on the peripheral side of the shoe mold groove 3, buffer grooves 7 are provided at both ends of the lower mold 1, and connecting water holes 11 are provided between the buffer groove 7 and the adjacent annular groove 5 and between the two annular grooves 5, a sealing unit 8 is installed in the buffer groove 7, and the two sealing units 8 are respectively connected with a water inlet pipe 10 and a water outlet pipe 9, which are respectively connected to the two adjacent buffer grooves 7, and a drainage unit 6 for draining the annular groove 5 and the water groove 4 is installed in the water groove 4.

[0025] like Figure 1 、 3As shown in FIG4 , the shoe mold structure of the present invention is similar to the existing shoe mold structure, such as a water-cooled sole mold disclosed in the patent with publication number CN207901559U. The main improvement of the present invention is that when the sole needs to be foamed, the raw materials are first heated in the shoe mold groove 3, and the upper mold 2 is covered on the lower mold 1. At this time, the raw materials are heated by external equipment to generate the sole. After the heating is completed, water is added to one of the buffer tanks 7 using the water inlet pipe 10. The other end of the water inlet pipe 10 can be connected to an external water pump, and the water pump can cool water from the outside. Water is pumped out of the box, and after entering the buffer tank 7, the water enters the two water tanks 4 and the two annular grooves 5 through the water holes 11. The drainage unit 6 blocks the water tank 4, so that the water fills the water tank 4 and the annular groove 5. Finally, the water enters another buffer tank 7, and is discharged from the outlet pipe 9 to the external cooling water tank for cooling, realizing water circulation. The water entering the water tank 4 and the annular groove 5 exchanges heat with the lower mold 1, and then absorbs the heat of the molded sole in the shoe mold groove 3, so that the sole is quickly cooled and formed, reducing the obstruction of cold water to the heat exchange of the sole, improving the cooling effect of the sole, facilitating temperature control, and facilitating the production of the sole.

[0026] like Figure 3 、 4 As shown, the sealing unit 8 includes two threaded sleeves 81 fixedly installed in the buffer groove 7, and the outer walls of the two threaded sleeves 81 are fixedly installed with sealing plates 82 by bolts. The sealing plate 82 seals the outer end opening of the buffer groove 7. An inner sleeve 83 is passed through and fixedly connected to the sealing plate 82. The water inlet pipe 10 and the water outlet pipe 9 are respectively sleeved on the outside of the inner sleeves 83 in the two sealing units 8; the water inlet pipe 10 transports water to the buffer groove 7 through the inner sleeve 83. Similarly, the water in the other buffer groove 7 is transported to the water outlet pipe 9 for discharge through the inner sleeve 83. The sealing plate 82 is fixed to the threaded sleeve 81 by bolts to achieve sealing of the buffer groove 7. The sealing plate 82 is detachable, which is convenient for processing the lower mold 1 and at the same time avoids clogging of the water hole 11, which is convenient for cleaning.

[0027] like Figure 2 、 3As shown in Figure 5, the drainage unit 6 includes a bottom plate 61 installed on the bottom surface of the lower mold 1 and blocking the water tank 4. A plurality of hydraulic cylinders 62 are fixedly installed on the upper surface of the bottom plate 61. A sleeve 63 is fixedly installed on the movable end surface of the hydraulic cylinder 62. The sleeve 63 is movably sleeved in the annular groove 5. A plurality of springs 67 are fixedly installed in the sleeve 63. The upper end of the spring 67 is fixedly connected with an extrusion plate 64, and the extrusion plate 64 is slidably connected in the sleeve 63; the bottom plate 61 blocks the water tank 4. When water is supplied to the water tank 4 and the annular groove 5, the input water will not continue to fall after being blocked by the sleeve 63 and the extrusion plate 64. After the cooling of the sole in the shoe mold groove 3 is completed, the water inlet pipe 10 stops supplying water. At this time, the hydraulic cylinder 62 is started to make the sleeve 63 rise. The extrusion plate 64 and the sleeve 63 first squeeze the water in the water tank 4 through the water hole 11 The shoe sole is then cooled and the shoe is put into the water tank 4. When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole. When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole. When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole. When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole. When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole. When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole.

When the shoe sole is cooled, the hydraulic cylinder 62 is lowered to the bottom of the shoe sole.

[0028] like Figure 5 As shown, a plurality of slide rods 65 are fixedly installed on the bottom surface of the extrusion plate 64, and the other end of the slide rod 65 passes through the sleeve 63 and is fixedly connected to a stopper 66; when the sleeve 63 slides, the sleeve 63 and the outer wall of the slide rod 65 slide, and the slide rod 65 restricts the extrusion plate 64, so that the sliding of the sleeve 63 and the outer wall of the extrusion plate 64 is stable. At the same time, the stopper 66 restricts the extrusion plate 64 through the slide rod 65, preventing the extrusion plate 64 from sliding out of the sleeve 63, thereby improving stability.

[0029] like Figure 2 、 3 As shown, the bottom plate 61 is movably mounted on the bottom surface of the lower mold 1, and the bottom plate 61 is fixed to the lower mold 1 by bolts; the bottom plate 61 is detachable, thereby facilitating the removal of the drainage unit 6 from the sink 4 for cleaning and maintenance.

[0030] like Figure 3 、 4 As shown, there are multiple water holes 11 between the buffer groove 7 and the adjacent annular groove 5 and between two annular grooves 5, and the multiple water holes 11 are evenly distributed; the multiple arranged water holes 11 can easily squeeze out the water in the water groove 4 and the annular groove 5, which is convenient for drainage.

[0031] like Figure 3 As shown, the distance between the top wall of the water trough 4 and the inner bottom surface of the shoe mold groove 3 is equal to the minimum distance between the side wall of the annular groove 5 and the inner side wall of the shoe mold groove 3, and the distance between the top wall of the water trough 4 and the inner bottom surface of the shoe mold groove 3 is not greater than 4 cm; the minimum distances between the water trough 4 and the annular groove 5 and the shoe mold groove 3 are all small, which makes it convenient for the water in the water trough 4 and the annular groove 5 to cool and shape the sole in the shoe mold groove 3.

[0032] 1 and 1, and then the upper mold 2 is placed on the lower mold 1. At this time, the raw materials are heated by external equipment to generate the sole. After the heating is completed, water is added to one of the buffer tanks 7 by using the water inlet pipe 10. The other end of the water inlet pipe 10 can be connected to an external water pump. The water pump can pump water from an external cooling water tank. After the water enters the buffer tank 7, it enters the two water tanks 4 and the two annular grooves 5 through the water holes 11. The water entering the water tank 4 is located on the sleeve box 63 and the extrusion plate 64, so that the water fills the water tank 4 and the annular groove 5. Finally, the water enters the other buffer tank 7 and is discharged from the water outlet pipe 9 to the external cooling water tank for cooling, realizing water circulation. The water entering the water tank 4 and the annular groove 5 absorbs the heat of the molded sole in the shoe mold groove 3 by heat exchange with the lower mold 1, so that the sole is quickly cooled and formed. After the cooling of the sole in the shoe mold groove 3 is completed, the water inlet pipe 10 stops supplying water. At this time, the hydraulic cylinder 62 is started to make the The sleeve 63 rises, and the squeezing plate 64 and the sleeve 63 first squeeze the water in the water tank 4 into the buffer tank 7 through the water hole 11 until the squeezing plate 64 contacts the top wall of the water tank 4. At this time, the sleeve 63 continues to rise, and the sleeve 63 slides on the outer wall of the squeezing plate 64 and the slide rod 65, and drives the spring 67 to compress. The sleeve 63 is inserted into the annular groove 5, and the water in the annular groove 5 is squeezed out from the water hole 11. Then, when the raw material is heated, there is no cooling water in the water tank 4 and the annular groove 5, avoiding the water tank 4 from being heated. The water in the annular groove 5 affects the temperature of the raw material heating. When the heating step is completed and the sole needs to be cooled, the hydraulic cylinder 62 descends, and the sleeve 63 is moved into the water trough 4. Under the elastic force of the spring 67, the upper end surface of the extrusion plate 64 and the sleeve 63 are made level. The block 66 limits the position of the extrusion plate 64 through the slide rod 65. At this time, the water inlet pipe 10 can deliver water again. The water enters the water trough 4 and the annular groove 5 and is located above the sleeve 63 and the extrusion plate 64 to cool and shape the sole.
