For example, the ignition lock core guard plate commonly used in the automobile industry has the disadvantages of time and labor waste and low production efficiency if a process other than a powder metallurgy process is adopted due to small volume and complex shape.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an adopt ignition lock core backplate mould of powder metallurgy technology production usefulness.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the ignition lock cylinder guard plate mold comprises a bottom mold, a middle mold and an upper mold, wherein the bottom mold comprises a base, a cylindrical lower pressure-bearing column is arranged on the base, and a rectangular molding block is arranged on the end face of the lower pressure-bearing column; the middle die is provided with a circular molding cavity hole, and the lower pressure bearing column is positioned in the molding cavity hole; the upper end surface of the middle mold is provided with a molding groove, the molding groove and the molding cavity hole form a stepped hole, and symmetrical lugs are arranged in the molding groove; the upper die comprises a top seat, the top seat is connected with a cylindrical upper pressure bearing column, the upper pressure bearing column corresponds to a modeling groove, the modeling groove is punched, a side face of the upper pressure bearing column is provided with a avoiding groove, the avoiding groove corresponds to a convex block, the middle part of the upper pressure bearing column is provided with a rectangular groove, and the rectangular groove corresponds to a modeling block.
In order to avoid sharp edges and reduce burrs, the connection part of the modeling block and the end part of the lower bearing column is in transition connection through an arc section.
Specifically, in order to realize the molding on ignition lock core backplate surface, the terminal surface of lower pressure-bearing post has the sunken groove, rectangle molding piece is located the sunken inslot, and in the same way, in order to avoid the edge sharp-pointed, the reduction burr appears, the junction passes through circular arc section transitional coupling between the terminal surface of lower pressure-bearing post and the sunken groove.
The utility model discloses the mould is suitable for powder metallurgy technology production, and the ignition lock core backplate of production is efficient, and is with low costs. Due to the transition design of the arc section of the mold, the produced ignition lock cylinder guard plate is smooth in edge and free of burrs, and meanwhile, the end part of the mold can be effectively prevented from being damaged.
