Abstract
The invention relates to a die-casting mold provided with a bottom inner loose core. A second loose core structure and an oblique loose core structure are mounted at the positions on the left and on the right between an upper mold base and a lower mold base. A bottom inner loose core structure is mounted below the second loose core structure and on the lower end face of the lower mold base, and comprises a bottom slider, a bottom slider loose core and a bottom loose core cylinder. The bottom loose core cylinder is positioned below the lower mold base. The bottom slider is mounted on a spindle of the bottom loose core cylinder. The bottom slider loose core is mounted on one end, close to the lower mold base, of the bottom slider and is long-strip shaped, and one end of the bottom slider loose core obliquely penetrates through the lower mold base and a lower mold core and is inserted into the middle position of a lower portion of a mold cavity. Bottom loose core pressing bars connected with the bottom loose core cylinder are arranged on the front side and the back side of the bottom slider. The die-casting mold provided with the bottom inner loose core has the advantages of simple structure, high production efficiency, guaranteed product quality, lower mold manufacturing cost and the like.
