Description

Technical Field

[0001] The utility model relates to the field of accessories for die-casting molds, and particularly to a feeding insert for a die-casting mold which is convenient for demolding. Background Art

[0002] Conventional die-casting molds usually only need gate structures and runner structures to facilitate the entry of molten metal into the mold cavity, so as to facilitate the molding of products in the mold cavity. However, this structure can only be applied to ordinary molds. When the volume of the product is too large and a three-plate die-casting mold is required, a feeding insert for facilitating the entry of molten metal into the mold needs to be added. The conventional feeding insert is similar to the gate structure, which is not conducive to product demolding, and the shank in the feeding insert is not easy to be taken out from the feeding insert. To solve the above problems, the structure needs to be modified. Summary of the Invention
