Description

Technical Field

[0001] The utility model relates to the technical field of foaming devices, in particular to a thermoplastic elastomer foaming device. Background Art

[0002] At present, there are two conventional molding methods for ETPU shock-absorbing midsoles. One is to first use TPU material to inject the sole blank, and then use supercritical foaming to fully foam the TPU material under a heating and pressurizing environment to obtain a foamed molded body. The other is to use supercritical foaming to foam TPU material particles into ETPU particles under a heating and pressurizing environment, and then obtain a foamed molded body after secondary foaming. However, in actual production, the gas can only enter the TPU material after the TPU material is heated to soften. Therefore, it takes a long time to heat and pressurize the TPU material at the same time, which is not suitable for actual production.

[0003] A thermoplastic elastomer foaming device is disclosed in the Chinese utility model patent application disclosure CN 212653749 U. When a pressurizing mechanism infiltrates an inert gas into softened thermoplastic elastomer particles, a heating mechanism can simultaneously heat a new batch of thermoplastic elastomer particles to soften them. The device is operated in an assembly line to improve the foaming efficiency. However, the device is large in size and occupies more space, and has more foaming steps, thereby reducing the foaming efficiency. Utility Model Content
