Description

Technical Field

[0001] This utility model relates to the field of shoe sole processing technology, specifically to a shoe sole injection mold with fast cooling speed. Background Technology

[0002] The sole is the part of a shoe that comes into direct contact with the ground. It needs to be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, and elastic to fit people's feet after they put on the shoes. Therefore, there are strict requirements for the size of the sole during the processing of the sole. Generally, during the injection molding process of the sole, the raw material of the sole after injection molding should be cooled and solidified as soon as possible.

[0003] A search revealed that Chinese patent CN213648480U discloses a rapid-cooling shoe sole injection mold, comprising a lower mold and a lower mold core disposed within the lower mold core cavity of the lower mold, as well as a liquid inlet connector and a liquid outlet connector. The liquid inlet connector is mounted on the lower mold, forming a liquid inlet cavity with the lower mold, and the liquid outlet connector is mounted on the lower mold, forming a liquid outlet cavity with the lower mold. Several cooling channels are provided between the lower mold core and the lower mold, with both ends of the cooling channels communicating with the liquid inlet cavity and the liquid outlet cavity, respectively. Heat exchange is achieved between the coolant and the lower mold and the lower mold core, providing a certain cooling effect. However, the coolant cannot be circulated, and the cooling channels are only provided in the lower mold and the lower mold core, resulting in a small cooling area in contact with the shoe mold and an insignificant cooling effect, thereby reducing production efficiency. Furthermore, the hot air generated during the injection molding of the shoe sole affects the quality of the shoe sole production.

[0004] Therefore, we propose a shoe sole injection mold with a fast cooling rate. Utility Model Content

[0028] A mold cavity 5 is fixedly installed inside the lower mold base 3. A cooling tank 14 is fixedly installed in the center of the mold cavity 5. A partition 15 dividing the mold cavity 5 into four parts is fixedly installed on the outer wall of the cooling tank 14. A water inlet hole 16 is opened on the bottom side of the cooling tank 14. A cooling plate 17 is fixedly installed inside the cooling tank 14. A cooling channel 18 opposite to the position of the partition 15 is opened on the inner wall of the cooling tank 14. The partition 15 and the cavity of the mold cavity 5 are hollow, and water outlet holes 19 are opened at the four corners of the mold cavity 5.

[0029] A blower 12 is fixedly installed on the outer wall of the left side of the lower mold base 3, and three sets of ventilation holes 13 are opened on the outer wall of the right side of the lower mold base 3. The cavity of the lower mold base 3 is hollow.

[0030] In this embodiment, it should be further explained that when the fast-cooling shoe sole injection mold is in use, the cooling tank 14, cooling plate 17, partition plate 15 and cooling channel 18 can transport the cooled water to the perimeter of each shoe mold, increasing the cooling area, resulting in fast cooling and improved production speed. At the same time, the blower 12 and ventilation hole 13 can blow the hot air brought by the injection mold out from the inside of the lower mold base 3, improving the production quality of the shoe sole.

[0031] In this embodiment, it should be noted that the cooling plate 17 is in the shape of a circular groove, and the height of the cooling plate 17 is adapted to the height of the cooling channel 18.

[0032] This can increase the cooling time of the water, thereby improving the cooling effect.

[0033] In this embodiment, it should be noted that a water tank 6 is fixedly installed on the top side of the base 1, a water pump 21 is mounted on the top of the water tank 6, an input pipe 22 is fixedly installed at the input end of the water pump 21, an output pipe 23 is fixedly installed at the output end of the water pump 21, the output pipe 23 is connected to the water inlet 16, and the bottom end of the input pipe 22 is located inside the water tank 6.

[0034] The water in water tank 6 can also be cooled, thereby improving cooling efficiency.

[0035] In this embodiment, it should be noted that a water outlet pipe 20 is fixedly installed on the bottom side of the water outlet 19, and the bottom end of the water outlet pipe 20 is located inside the water tank 6.

[0036] This allows for the recycling of water and the conservation of resources.

[0037] In this embodiment, it should be noted that four sets of feed ports 8 are provided on the top side of the upper mold base 4, and the feed ports 8 are positioned opposite to the mold cavity 5.

[0038] This allows for precise injection molding of shoe sole materials, preventing resource waste.

[0039] In this embodiment, it should be noted that four sets of pins 9 with opposite positions are fixedly installed on the bottom side of the upper mold base 4, and the top side of the lower mold base 3 is provided with insertion holes 11 with opposite positions to the pins 9. The bottom end of the pins 9 is provided with threads 10, and the threads 10 are fitted with matching bolts.

[0040] This allows for a tight seal of the mold cavity 5, preventing air impurities from entering.

[0041] In this embodiment, it should be noted that two sets of handles 7 are fixedly installed on the left and right sides of the upper mold base 4.

[0042] This makes it easier to lift the upper mold base 4 away.

[0043] The working principle and usage process of this utility model are as follows: When using this fast-cooling shoe sole injection mold, first fix the upper mold base 4 to the lower mold base 3 through the insertion hole 11 and the plug 9, then inject cold water into the water tank 6, start the water pump 21 and the cooling plate 17, and transport the water to the cooling tank 14 through the input pipe 22, the output pipe 23 and the water inlet hole 16. After being cooled by the cooling plate 17, the mold cavity 5 is pre-cooled through the cooling channel 18, and the water then flows into the water tank 6 from the water outlet hole 19 and the water outlet pipe 20 to form a water circulation. Then the shoe sole raw material can be injected from the feed port 8 for shoe sole injection. After the injection and cooling are completed, the water pump 21 can be turned off, and then the upper mold base 4 can be lifted away by the handle 7 to remove the shoe sole.
