Description

TPU material processing die Technical Field The utility model relates to the technical field of TPU material processing, in particular to a TPU material processing die. Background The TPU material is thermoplastic plastic and has high elasticity, high strength, wear resistance, oil resistance and temperature resistance, so that the TPU material can be applied to the field of electronic products, and can be matched with a die to be processed into products such as mobile phone shells or protective sleeves, and the like, thereby playing a role in protecting the electronic products such as mobile phones. When processing the mobile phone shell, current mold processing uses the processing platform as the main part, processing platform top side both ends symmetry is provided with the pneumatic cylinder, and the hydraulic rod level sets up in processing platform top side, both sides pneumatic cylinder output is fixed with the mould body respectively, mould chamber has been seted up to the mould body inboard, the mould top side is fixed with the inlet pipe, and inlet pipe and the inboard intercommunication of mould, drive both sides mould through the pneumatic cylinder and merge, pour into molten state's TPU material into through the inlet pipe, after its cooling, control pneumatic cylinder separates the both sides mould, and take out the work piece by the mould intracavity side, thereby accomplish the processing of moulding plastics, this mould simple structure and convenient to use.
