[0002] The undercut structure is a common structural form in product design. It is usually used to achieve specific functions or appearance effects of the product. However, in mold design, due to the existence of the undercut part, the mold is easily hindered during demoulding, resulting in product strain or mold damage. Therefore, a mold that can smoothly realize undercut core removal is needed.

[0003] In the existing technology, the traditional mold needs to make a core at the undercut area. After the product is injection molded, the core is taken out and manually peeled off or the product is punched out using a machine. However, in actual use, it needs to be manually peeled off or the product needs to be punched out using a machine during separation, which easily increases the tediousness of the staff's work and production time, making the entire production process time-consuming and labor-intensive, and unable to make the device achieve high production efficiency. Therefore, it is necessary to improve a product mold with an undercut core. Utility Model Content
