[0002] A mold is a variety of molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. A mold generally consists of a front mold and a rear mold. A mold cavity for molding objects is formed between the front mold and the rear mold. The front mold generally refers to the ejection side of the mold, and the rear mold generally refers to the side connected to the fixed machine. The two can be separated and combined. When the two are separated, the molded object can be taken out. When they are closed, the blank is injected into the mold cavity for molding. When demolding, the front mold generally moves away from the rear mold. However, when molding objects with more complex shapes, if the shape of the object has complex structures such as buckles, for example, the outer shell of a kettle has a handle, when the front mold is separated from the rear mold, it is easy to damage the handle and thus damage the molded object, making it impossible to demold.

[0029] The implementation principle of this embodiment is:
[0030] During demoulding, the first template 1 and the second template 14 move in the direction away from the rear mold. During the movement, the upper mold core 2 and the fixed mold core 15 move synchronously with the first template 1 and the second template 14. Since the hook block on the rear mold hooks the transverse groove 12, the left mold core 3 and the right mold core 4 always press against the rear mold. At the same time, due to the action of the guide groove 5 and the first spring 9, the left mold core 3 and the right mold core 4 move relative to the first template 1 along the direction of the guide groove 5, causing the left mold core 3 and the right mold core 4 to move toward the left and right sides relative to the rear mold, thereby causing the left mold core 3 and the right mold core 4 to separate from the left and right sides of the molded object respectively. At the same time, the core pulling 13 is synchronously separated from the molded object. At this time, the second spring 19 gradually extends, the first ejector pin 17 still presses against the rear mold, and the second ejector pin 18 presses against the molded object, thereby helping the core pulling 13 to separate from the molded object until the hook block separates from the transverse groove 12. The left mold core 3 and the right mold core 4 follow the second template 14 due to the restriction of the limit groove 7 to separate from the rear mold and complete demoulding.
