Description

Technical Field

[0001] The utility model relates to the field of wax injection molds, in particular to a structure and a mold for fixing a wax injection iron core of a mold head. Background Art

[0002] At present, the wax injection mold usually installs the insert on the base plate, and the iron core is inserted on the insert. When the wax mold is processed, the equipment pushes the upper mold to move toward the lower mold. The upper mold pushes the base plate together during the movement, so that the upper mold and the lower mold are closed on the base plate. After the closing is completed, wax is injected into the wax injection mold. After the wax injection is completed, the equipment controls the upper mold and the lower mold to separate, and the robot takes out the wax mold and the iron core together. Because in the closing process, the iron core is only inserted into the insert, and the upper and lower molds are symmetrically provided with iron core accommodating grooves. If the upper mold pushes the base plate together during the movement, the base plate may shake, causing the position of the iron core to shift, and then the iron core does not enter the iron core accommodating groove when the upper and lower molds are closed, resulting in damage to the upper mold or the lower mold.
