Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a high-stability zinc alloy die-casting mold with a core-pulling structure. Background Art

[0002] Die casting is a method of obtaining a casting by filling liquid or semi-liquid metal into the cavity of a die-casting mold at high speed under high pressure and rapidly solidifying it under pressure. The core pulling structure is the most commonly used mechanism in die-casting molds. When the casting has inner concave or side holes that are different from the mold opening direction and hinder the direct demolding of the die casting, the parts with side holes or concave must be made into movable cores, and then combined with the core pulling structure to improve product quality.

[0003] The existing referenceable Chinese utility model patent with announcement number CN219966399U discloses a high-stability zinc alloy die-casting mold with a core-pulling structure. The utility model includes a base; a lower mold is provided on the top of the base; an upper mold is provided above the lower mold; a cavity is provided in the lower mold; a group of through holes are provided on the inner wall of each side of the cavity; and a group of core-pulling mechanisms are provided on the outer wall of each side of the lower mold. When the side recesses or side holes of the castings to be die-cast are of different sizes or positions, the utility model takes out the corresponding groups of sealing plugs, and then the core columns of different shapes are clamped in the corresponding groups of card slots, and then the sealing plate is re-inserted into the through hole, so that the core column enters the cavity, and the die-casting work can be performed again, which improves the compatibility of the die-casting work.

[0004] During use, the above-mentioned zinc alloy die-casting mold can meet the working requirements of castings with different side hole sizes or positions, but it is necessary to align and connect several sealing gaskets and slots, which leads to waste of use during operation and reduces the use of the zinc alloy die-casting mold. At the same time, the sealing gasket and the slot docking structure is single, and the length of the fixed plate structure is shorter than the outer side of the lower mold, so the lower mold is easily clamped and positioned, which may cause positioning shaking, resulting in the lower mold being offset, affecting the normal operation of the casting.
