This utility model, by setting up components such as a pressure rod, a push rod, and a second spring, allows the second spring to drive the push rod to move when the upper mold and lower mold are separated, so that the push rod lifts the molded workpiece from the lower mold, thereby facilitating demolding of the lower mold. This solves the problem that the injection mold for the ignition coil housing is inconvenient to demold during use and is not convenient to use.

[0013] 2. By setting up components such as a limiting plate, a limiting block, and a second spring, the limiting plate and the limiting block can be slidably connected by the elastic force of the second spring, so that the limiting plate can limit the upper mold and keep the upper mold and lower mold stable when they are closed.
