Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a lettering mold. Background Technique

[0002] A mold is a tool that, under the action of external force, uses a specific shape to form a blank (solid and liquid) into a workpiece with a certain shape and size. Molds are extremely widely used in forging, stamping, powder metallurgy pressing, die casting, and the forming processes of compression molding and injection molding of products such as engineering plastics, rubber, and ceramics. Molds are generally divided into two parts, divided into a moving mold and a fixed mold according to the motion state, and divided into a concave mold and a convex mold according to the shape. There are various types of molds such as steel molds, iron molds, tin molds, wooden molds, gypsum molds, clay molds, and so on.

[0003] The existing lettering mold includes: an upper template and a lower template. The workpiece is positioned and placed on the lower template, and the lettering mold is fixed on the upper template. The upper template drives the lettering mold to move downward to engrave the workpiece. However, the existing lettering mold is not convenient for replacing the font template, thereby reducing the working efficiency of the lettering mold.

[0004] Therefore, we propose a lettering mold. Content of the Utility Model
