A brush for quickly painting a test mold and a method of using the brush

Abstract

The present invention discloses a brush for quickly painting a test mold and a method for using the brush, comprising a long rod, a handle arranged on the long rod, a cylindrical brush head arranged on the long rod for painting the test mold, and a foldable frame arranged inside the cylindrical brush head. When painting large-sized and small-sized test molds, the state of the brush head can be changed by grasping the long rod or a cover. If the size of the test mold is small, the height of the side of the brush head can be reduced by holding the handle, and the release agent will not overflow from the test mold when painting the side wall of the small test mold. After the release agent is squeezed out to the bottom of the test mold, the excess release agent at the bottom can be absorbed back into the brush head after the release agent is brushed back and forth. If the size of the test mold is large, when the cover is held, the long rod is pulled downward due to gravity, and the length of the side of the brush head is stretched to the longest, and the frame can prevent the brush head from falling off, thereby improving the efficiency of painting the side wall of the large test mold.
