[0006] The bottom end of the lower mold has a lower groove, and multiple first through holes are provided at the top end of the lower mold around the forming groove, communicating with the lower groove. The top end of the upper mold has an upper groove, and multiple second through holes are provided at the bottom end of the upper mold around the forming protrusion, communicating with the upper groove. The bottom end of the upper mold has multiple plugs communicating with the second through holes.

[0007] Both the first through hole and the second through hole are fitted with drainage components via threaded connections. The drainage components include a threaded sleeve, a central shaft with one end fixed to the inner cavity of the threaded sleeve by a support rod and the other end extending outward, and a spiral plate fixedly sleeved on the central shaft.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0026] Combination Figure 1-6 As shown, this embodiment provides a rapidly cooling rubber sole molding die, including: a main body 100.

[0027] The main structure 100 includes a lower mold 110, an upper mold 120 installed above the lower mold 110, two sealing plates 130 respectively fixed to the bottom of the lower mold 110 and the top of the upper mold 120 by bolts, a drain pipe 140 installed on one side of the lower mold 110 and communicating with the inner cavity of the lower mold 110, and a water inlet pipe 150 installed on one side of the upper mold 120 and communicating with the inner cavity of the upper mold 120.

[0028] The lower mold 110 has a molding groove at its top and the upper mold 120 has a molding protrusion at its bottom. The two work together to form a molding space for the injection molding of shoe soles.

[0029] A lower groove 111 is formed at the bottom end of the lower mold 110. Multiple first through holes 112 are provided at the top end of the lower mold 110, surrounding the forming groove, and communicating with the lower groove 111. Simultaneously, an upper groove 121 is formed at the top end of the upper mold 120. Multiple second through holes 122 are provided at the bottom end of the upper mold 120, surrounding the forming protrusion, and communicating with the upper groove 121. Multiple plugs 123 are provided at the bottom end of the upper mold 120, communicating with the second through holes 122. The positions of the first through holes 112 and the second through holes 122 are relative to each other. Correspondingly, the outer diameter of the plug 123 is equal to the inner diameter of the first through hole 112. With this setting, when the upper mold 120 and the lower mold 110 are closed, the plug 123 is inserted into the first through hole 112, so that the first through hole 112 and the second through hole 122 are connected, which facilitates the passage of cooling water and quickly removes the heat in the upper mold 120 and the lower mold 110. In addition, both the first through hole 112 and the second through hole 122 are through-holes, which effectively increases the convenience of the mold itself during the processing.

[0030] The sealing plate 130 includes a cover plate 131 and a rubber sealing gasket layer 132 fixed to one side of the cover plate 131. The bottom end of the lower mold 110 and the top end of the upper mold 120 are both fixed with sealing plates 130 by threads, which are used to seal the lower groove 111 and the upper groove 121 to form a closed space.

[0031] The drain pipe 140 is connected to the lower groove 111 and is used to discharge the cooling water that enters the lower groove 111. The inlet pipe 150 is connected to the upper groove 121 and is used to guide the cooling water into the upper groove 121.

[0032] Both the first through hole 112 and the second through hole 122 are threadedly connected to a draining element 160. The draining element 160 includes a threaded sleeve 161, a central shaft 162 with one end fixed to the inner cavity of the threaded sleeve 161 by a support rod and the other end extending outward, and a spiral plate 163 fixedly sleeved on the central shaft 162. An external thread is provided on the outer surface of the threaded sleeve 161. The inner wall of the first through hole 112 near the lower groove 111 and the inner wall of the second through hole 122 near the upper groove 121 are also threaded. Both are provided with internal threads, which mesh with each other to facilitate the installation and disassembly of the threaded sleeve 161. The central shaft 162 is used to fix the spiral plate 163. The outer edge of the spiral plate 163 is close to the inner wall of the first through hole 112 and the second through hole 122, forming a spiral flow channel in the inner cavity of the first through hole 112 and the second through hole 122. This can prolong the time for water to pass through the first through hole 112 and the second through hole 122, so that the water can fully absorb and carry away the heat on the mold, further improving the heat dissipation efficiency.

[0033] The working principle and usage process of this utility model are as follows: During use, the upper mold 120 and the lower mold 110 are closed to form a space for injection molding of rubber shoe soles. At the same time, the plug 123 at the bottom of the upper mold 120 is inserted into the first through hole 112 of the lower mold 110, and injection molding can begin. After the rubber shoe sole is injection molded, cooling water enters the upper groove 121 through the water inlet pipe 150 on one side of the upper mold 120, then enters the second through hole 122 through the upper groove 121, and enters the first through hole 112 through the plug 123. It then enters the lower groove 111 through the first through hole 112 and is discharged through the drain pipe 140. When the cooling water passes through the first through hole 112 and the second through hole 122, it exchanges heat with the heat in the lower mold 110 and the upper mold 120, quickly removing the heat from the mold and cooling the lower mold 110 and the upper mold 120.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
