Injection mold for TPU protective sleeve

The invention discloses an injection mold for a TPU protective sleeve, and relates to the technical field of molds. Comprising a fixed mold, a lower mold core is embedded in the top of the fixed mold, a first temperature control cavity is formed in the bottom of the lower mold core, and an operation cavity is formed in the fixed mold; and an upper mold core is embedded in the bottom of the movable mold, and a second temperature control cavity communicating with the first temperature control cavity is formed in the top of the upper mold core. Compared with a common TPU protective sleeve injection mold in the market, the mode of combining air cooling and water cooling is adopted in the product, the upper mold core and the lower mold core are cooled through dehumidified low-temperature air, the situation of steam explosion is avoided, the heat preservation cavity is formed, only the lower mold core and the upper mold core are cooled when the preheated heating plate is stored, subjected to heat preservation and c
