Technical Field

[0002] For products with complex lateral structures (such as side holes, side grooves, side protrusions, etc.), the slider secondary core-pulling mold can ensure that these structures are not damaged during the demolding process, thereby producing high-quality products. Through the orderly movement of the slider and the core, the mold can automatically complete the core-pulling and reset processes, reducing the need for manual intervention and improving production efficiency.
[0003] In the existing technology, sliders and cores are designed in the mold, and these components will move along a predetermined trajectory during the mold opening process. The slider is usually installed on the moving mold and can move laterally relative to the moving mold; the core is used to form the complex structure inside the product. However, in the actual use process, since the trajectory of the mold core usually moves unidirectionally, and when producing products with a vertical slope, other more complex mold structures or processes need to be adopted to achieve similar functions, thereby increasing the production cycle and cost, making the design of the mold more complex, resulting in difficult maintenance and easier damage, and then requiring frequent replacement of components. Therefore, a slider secondary core-pulling mold needs to be improved. Content of the Utility Model
