Visual positioning paraffin embedding mold

The invention discloses a visual positioning paraffin embedding mold in the field of experimental tools. The visual positioning paraffin embedding mold comprises a base and an outer frame which are both transparent, a circle of limiting strip is arranged on the upper surface of the base, a sprue gate is formed in the top of the outer frame, a limiting opening is formed in the bottom of the outer frame, and the peripheral side walls of the outer frame are sealed; the limiting openings are clamped to the peripheries of the limiting strips, and positioning grid lines are arranged on the side walls of the base and the outer frame. Liquid paraffin is poured from the sprue gate at the top of the outer frame, tissues are put in, the transparent base and the outer frame are adopted, the position of the tissues in the paraffin can be observed through the positioning grid lines, and the horizontal and vertical states of the tissues can be observed through the positioning grid lines, so that an experimenter can place th
