Problems solved by technology

[0002] Mold core, as the name suggests, refers to the precision parts used for the key operation of the center of the mold. The mold core is generally complex in structure, very difficult to process, and high in cost. Often, the labor cost of manufacturing is much greater than the material itself.
[0003] At present, the diameter of the connection hole set by the existing mold core with variable inner diameter is mostly fixed. When assembling with the shaft assembly of the mold, most of them can only be connected with the shaft assembly whose diameter matches, which greatly reduces the The scope of application of the mold core is limited, and most of the existing mold cores do not have the function of rotation after assembly, and there may be some inconvenience when used in some specific cases

Abstract

The invention discloses a mold core with a variable inner diameter, which belongs to the technical field of mold accessories. A through hole is opened in the center of the base plate, and a fixing plate is clamped on the surface of the base plate. A round hole is opened in the center of the fixing plate. The inner diameter is larger than the inner diameter of the through hole, the surface of the fixed plate is fixedly connected with a spacer, the surface of the spacer is fixedly connected with a conical toothed disc, and the surface of the conical toothed disc is provided with circular and equidistant teeth. The surface is fixedly connected with a mounting plate, and the surface of the mounting plate is provided with annular and equally spaced chute. The variable inner diameter mold core is provided with a tapered tooth plate to make the mold core have the function of rotation, and the anti-skid block and anti-skid groove can avoid the cone. The tooth plate slips between the base plate of the mold core when it rotates, which improves the stability of the mold core, and the T-shaped chute set on the mounting plate can limit the installation position of the adjustment block, and also makes the adjustment block have a horizontal sliding adjustment position The function improves the assembly scope of the mold core.
