[0005] By adopting the above technical solution, the static mold core is fixed to the static mold fixing plate using the static mold front screws, and the static mold is locked laterally using the static mold lateral locking structure. During installation, the static mold core and the lateral locking structure are simply positioned normally and fixed simultaneously. When disassembling the static mold core, the static mold lateral front screws and the static mold front screws are first removed. Then, a screw one size larger than the static mold side front screw is first used to push the static mold lateral locking structure out through the static mold lateral locking threaded hole. Finally, a screw one size larger than the static mold front screw is used to push the static mold core out through the static mold locking threaded hole.

[0012] Preferably, an inclined surface is provided on the inner wall of the ejector hole.

[0013] By adopting the above technical solution, such an arrangement makes it easier to smoothly position the ejector pin when the movable mold core is installed from the front.

[0014] Preferably, the static mold lateral locking structure is arranged on at least one side of the static mold core, and at least one static mold lateral locking structure is arranged on each side of the static mold core.
