A universal mold for hardware with replaceable mold core

Abstract

The invention discloses a mold core-replaced hardware general mold, and relates to the field of molds. The mold core-replaced hardware general mold comprises a mold main body; the mold main body comprises an upper mold base; a mold core is embedded in the upper mold base; a first pin column is welded in the bottom center of the mold core; multiple second pin columns are welded on the bottom edge of the mold core in a staggering mode; fixed holes are symmetrically formed in the two sides, near the multiple second pin columns, of the mold core; a mold core fixed base is arranged at the bottom end of the mold core; a first pin hole is formed in the top center of the mold core fixed base; multiple second pin holes are formed in the top edge of the mold core fixed base in a staggering mode; fastening pieces are arranged at four top angles of the mold core fixed base one by one; multiple third pin columns are welded at the bottom, near the outer edge, of the mold core fixed base at equal intervals; and a lower mold base is arranged at the bottom end of the mold core fixed base. Through the structures, the mold core replacement is realized; and the mold core-replaced hardware general moldis simple in structure, and saves resources.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a universal mold for hardware with replaceable mold cores. Background technique [0002] With the development of society, molds are applied to all walks of life. Most of the current molds generally include upper mold base, lower mold base, guide pillars, contour sleeves, springs and mold cores. The inner mold structure and mold base are composed of The overall mold structure, under normal circumstances, the inner mold structure and the mold base are fixed together, that is, one set of inner mold structure corresponds to one set of mold base. When processing different products, it is usually necessary to replace the mold core and the mold base together so that the mold core It is inconvenient to replace, and a set of mold cores generally only corresponds to a set of mold bases, and frequent replacement wastes resources. In addition, although CN206765263U discloses an easy-to-disassemble mold...

[0002] With the development of society, molds are applied to all walks of life. Most of the current molds generally include upper mold base, lower mold base, guide pillars, contour sleeves, springs and mold cores. The inner mold structure and mold base are composed of The overall mold structure, under normal circumstances, the inner mold structure and the mold base are fixed together, that is, one set of inner mold structure corresponds to one set of mold base. When processing different products, it is usually necessary to replace the mold core and the mold base together so that the mold core It is inconvenient to replace, and a set of mold cores generally only corresponds to a set of mold bases, and frequent replacement wastes resources. In addition, although CN206765263U discloses an easy-to-disassemble mold in the prior art, CN102861851A relates to a mold with replaceable mold cores, but The above molds cannot realize easy disassembly and core replacement at the same time, and the core replacement function is limited to cores of the same size
