Abstract
The invention discloses a U-F shaped magnetic core die. A lower punch matched with a cavity is arranged at the other end of the cavity, and both an upper punch and the lower punch are of cylinders with the same U-shaped cross sections. The cylinders are matched with U-shaped slot holes formed in the cavity. Straight walls penetrating the slot holes are arranged on one side of the slot holes. A step is arranged on a molding face of the upper punch, an ejector plate is arranged on a base of the lower punch, and the ejector is connected with an air cylinder arranged on a fixed die plate. The lower punch, the cavity and the upper punch are matched one another to form a molding cavity of the magnetic core as needed, magnetic powder is filled into the molding cavity, is punched by the upper punch and then extruded and shaped, and the molded magnetic core can be ejected conveniently by the air cylinder arranged on the fixed die plate. Besides, due to height-adjustable supporting columns arranged on the fixed die plate, the die is more flexible to regulate. The U-F shaped magnetic core die is simple in structure, convenient to operate and high in molding efficiency.
Description
technical field [0001] The invention relates to the technical field of magnetic cores, in particular to a UF type magnetic core mold. Background technique [0002] Due to the simple structure, inaccurate positioning, uneven force, and poor adjustability of the magnetic core molds in the prior art, the yield rate of the magnetic core is low and the production efficiency is low. Therefore, a mold with strong adjustability has been developed. , The magnetic core mold with high production efficiency has become a problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a magnetic core mold with simple structure, convenient operation and high molding efficiency. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A UF type magnetic core mold, comprising a movable mold bottom plate and a fixed mold bottom plate, a support column is arranged on the fixed mold bottom plate, and a m...
