[0044] See Figures 1 to 3 This utility model provides a molding device for shoemaking, including a body 1. The body 1 is provided with an upper mold body 2, a first lower mold body 3 and a second lower mold body 4. The first lower mold body 3 and the second lower mold body 4 are respectively matched with the upper mold body 2. The upper mold body 2 is driven to lift by a hydraulic cylinder 5. The first lower mold body 3 and the second lower mold body 4 are each provided with a lower mold cooling assembly 6. The upper mold body 2, the first lower mold body 3 and the second lower mold body 4 are each provided with an internal cooling pipe. The body 1 is provided with a cooling communication assembly 7 on one side corresponding to the lower mold cooling assembly 6. The first lower mold body 3 and the second lower mold body 4 are driven to move back and forth by a moving mechanism 8, so that the first lower mold body 3 has a first position and a second position, and the second lower mold body 4 has a third position and a fourth position.

[0045] The upper mold body 2 is provided with an upper mold inlet pipe 21 and an upper mold outlet pipe 22. The upper mold inlet pipe 21 and the upper mold outlet pipe 22 are respectively connected to the internal cooling pipe of the upper mold body 2. Both the upper mold inlet pipe 21 and the upper mold outlet pipe 22 are externally connected to a cooling liquid source.

[0046] The lower mold cooling assembly 6 includes a lower mold inlet pipe 61 and a lower mold outlet pipe 62. The lower mold inlet pipe 61 and the lower mold outlet pipe 62 are respectively connected to the internal cooling pipes of the first lower mold body 3 and the second lower mold body 4. A mold body solenoid valve 63 is installed on both the lower mold inlet pipe 61 and the lower mold outlet pipe 62.

[0047] The cooling connection assembly 7 includes a support plate 71 and a sliding assembly 72. The ends of the lower mold inlet pipe 61 and the lower mold outlet pipe 62 are both mounted on the sliding assembly 72. The sliding assembly 72 is slidably connected to the support plate 71. The support plate 71 is symmetrically provided with a coolant inlet pipe 73 and a coolant outlet pipe 74 on the front and rear sides of the upper mold body 2, respectively. A coolant solenoid valve 75 is provided on both the coolant inlet pipe 73 and the coolant outlet pipe 74. Both the coolant inlet pipe 73 and the coolant outlet pipe 74 are connected to an external coolant source.

[0048] When the first lower mold body 3 is in the first position, the second lower mold body 4 is in the third position; when the first lower mold body 3 is in the second position, the second lower mold body 4 is in the fourth position.

[0049] When the first lower mold body 3 is in the first position, the first lower mold body 3 is directly below the upper mold body 2;

[0050] When the first lower mold body 3 is in the second position, the lower mold inlet pipe 61 of the first lower mold body 3 is connected to the coolant inlet pipe 73 at the corresponding position of the support plate 71, and the lower mold outlet pipe 62 of the first lower mold body 3 is connected to the coolant outlet pipe 74 at the corresponding position of the support plate 71.

[0051] When the second lower mold body 4 is in the third position, the lower mold inlet pipe 61 of the second lower mold body 4 is connected to the coolant inlet pipe 73 at the corresponding position of the support plate 71, and the lower mold outlet pipe 62 of the second lower mold body 4 is connected to the coolant outlet pipe 74 at the corresponding position of the support plate 71.

[0052] When the second lower mold body 4 is in the fourth position, the second lower mold body 4 is directly below the upper mold body 2.

[0053] Using the above structure, during the molding of the shoe sole, with the upper mold inlet pipe 21 and upper mold outlet pipe 22 of the upper mold body 2, and with the cooperation of the first lower mold body 3, the second lower mold body 4, the lower mold cooling assembly 6, the cooling communication assembly 7, and the moving mechanism 8, after the shoe sole material is melted and molded by the upper mold body 2 and the first lower mold body 3, the liquid is introduced into the upper mold body 2 through the upper mold inlet pipe 21 and upper mold outlet pipe 22. This pre-shapes the position where the upper mold body 2 contacts the shoe sole material, so that the upper surface of the shoe sole can detach from the upper mold body 2. Then, the moving mechanism 8 moves the first lower mold body 3 and the second lower mold body 4, so that the first lower mold body 3 moves out of the upper mold body 2, and the second lower mold body 4 moves to directly below the upper mold body 2. At this time, the coolant inlet pipe 73 and coolant outlet pipe 74 of the support plate 71 of the cooling communication assembly 7 are connected to the lower mold inlet pipe 61 and lower mold outlet pipe of the first lower mold body 3. The liquid pipe 62 is connected, and the mold solenoid valve 63 and coolant solenoid valve 75 on the first lower mold 3 are opened to allow coolant to enter the first lower mold 3, so that the sole material can be cooled and shaped. At the same time, the upper mold 2 and the second lower mold 4 can melt and shape the sole material. After the sole in the first lower mold 3 has cooled and shaped, the sole in the first lower mold 3 can be removed. Then the mold solenoid valve 63 and coolant solenoid valve 75 can be closed, and new sole material can be put in. After the second lower mold 4 is shaped and detached from the upper mold 2, the first lower mold 3 is moved to directly below the upper mold 2 in the same way. The second lower mold 4 is moved out of the upper mold 2, and the sole material in the second lower mold 4 is cooled and shaped in the same way. This allows the next sole to be melted and shaped while the upper sole is cooled and shaped, thereby improving the production efficiency of the sole.

[0054] In one embodiment, see Figure 2 and Figure 3 The sliding component 72 includes a slider 721, on which a limiting block 722 is provided. Through holes 723 are provided through the slider 721 at positions corresponding to the lower mold inlet pipe 61 and the lower mold outlet pipe 62. The lower mold inlet pipe 61 and the lower mold outlet pipe 62 pass through the through holes 723. A sliding groove 711 and a limiting groove 712 are provided on the support plate 71. The slider 721 is embedded in the sliding groove 711 and the limiting groove 712. In practical applications, the slider 721 can be confined in the sliding groove 711 by the cooperation of the limiting block 722 and the limiting groove 712, so that the lower mold inlet pipe 61 and the lower mold outlet pipe 62 are always placed in the sliding groove 711, thereby enabling the opening and closing of the coolant inlet pipe 73 and the coolant outlet pipe 74.

[0055] The support plate 71 has connecting holes 713 at positions corresponding to the coolant inlet pipe 73 and the coolant outlet pipe 74. Both the coolant inlet pipe 73 and the coolant outlet pipe 74 pass through the connecting holes 713. In practical applications, the connecting holes 713 allow the coolant inlet pipe 73 and the coolant outlet pipe 74 to pass through the support plate 71, facilitating communication with the lower mold inlet pipe 61 and the lower mold outlet pipe 62.

[0056] A sealing ring 724 is provided in the through hole 723, with one end of the sealing ring 724 protruding from the surface of the slider 721. In practical applications, the sealing ring 724 prevents coolant from leaking out from the gap between the through hole 723 and the support plate 71 when coolant is introduced.

[0057] An mounting block 76 is installed at one end of the support plate 71, corresponding to the position of the slide groove 711 and the limiting groove 712. The mounting block 76 can be made of rubber. In actual use, the mounting block 76 can be used to install and lock the ends of the slide groove 711 and the limiting groove 712 to prevent the slider 721 and the limiting block 722 from disengaging from the slide groove 711 and the limiting groove 712.

[0058] In one embodiment, see Figure 1 and Figure 4 The moving mechanism 8 includes a moving base plate 81 and sliding plates 82 respectively disposed on both sides of the moving base plate 81. The first lower mold body 3 and the second lower mold body 4 are both mounted on the moving base plate 81. Step strips 811 are provided at the bottom of both sides of the moving base plate 81. The sliding plates 82 are provided with step grooves 821 corresponding to the positions of the step strips 811, with the step strips 811 embedded in the step grooves 821. The moving base plate 81 is driven by a cylinder 83, and the output end of the cylinder 83 is connected to the moving base plate 81 via a connecting plate 84. In practical applications, the cooperation between the step grooves 821 of the sliding plate 82 and the step strips 811 of the moving base plate 81 allows the moving base plate 81 to slide smoothly onto the sliding plate 82. In conjunction with the cylinder 83 and the connecting plate 84, the cylinder 83 drives the moving base plate 81 to move along the direction of the sliding plate 82, thereby moving the first lower mold body 3 and the second lower mold body 4 to achieve position switching between the first, second, third, and fourth positions.
