AI Technical Summary
In existing technologies, uneven spraying of release agent when using plastic molds leads to wear on the sliders and affects the service life of the mold.
The system employs a spraying and lubrication assembly. A geared motor drives the gears and gear rings to mesh, allowing the release agent to be sprayed evenly onto the lower mold. A hydraulic rod then moves the movable seat, resetting the sealing plate and ensuring that the release agent is evenly applied to the inside of the slider.
It achieves uniform spraying and lubrication of the release agent, improving the service life of the mold and the surface quality of the plastic products.
