Release agent supply device

The utility model relates to a release agent supply device. The release agent supply device comprises a first storage container, a first conveying pipeline, an electric pump, an energy accumulator and a first switch valve. The first storage container is used for containing release agent liquid and provided with a first liquid outlet part. And the first liquid outlet part is communicated with the liquid inlet end of the first conveying pipeline. The liquid outlet end of the first conveying pipeline is used for conveying the release agent liquid to the mold. The electric pump, the energy accumulator and the first switch valve are sequentially arranged on the first conveying pipeline. In the working process, the first switch valve is opened, the electric pump provides power to pump release agent liquid contained in the first storage container outwards into the first conveying pipeline, when the release agent liquid flows through the energy accumulator, the energy accumulator stabilizes the pressure of the releas
