Description

Technical Field

[0001] The utility model relates to the technical field of basketball inner tube demoulding, in particular to a basketball inner tube demoulding device. Background Technique

[0002] A basketball inner tube demoulding device is a device used to demould and separate a formed basketball inner tube from a mold during the production of the basketball inner tube.

[0003] At present, there are many basketball inner tube demoulding devices on the market. However, for general basketball inner tube demoulding devices, the staff directly presses and forms the basketball inner tube. After the formed basketball inner tube has a too high surface temperature, the staff needs to wait for it to cool down before demoulding. Moreover, between the lower module and the basketball inner tube, the staff needs to repeatedly pull and tug to take it out, which is extremely easy to cause wear of the basketball inner tube, reduce the demoulding effect of the device on the basketball inner tube, and reduce the practicability of the device.

[0004] Based on the above, the inventor found that: the staff directly presses and forms the basketball inner tube, but after the formed basketball inner tube has a too high surface temperature, the staff needs to wait for it to cool down before demoulding. Moreover, between the lower module and the basketball inner tube, the staff needs to repeatedly pull and tug to take it out, which is extremely easy to cause wear of the basketball inner tube. Therefore, in view of this, the existing structure is studied and improved to provide a basketball inner tube demoulding device, in order to achieve a more practical value purpose.
