The application discloses an injection mold. Two mold cores in the injection mold are arranged on two mold frames respectively. The two mold cores are arranged oppositely to form a molding chamber. A conformal water channel is formed between at least one mold core and the corresponding mold frame. The conformal water channel is arranged corresponding to the molding chamber. The conformal water channel continuously extends between the mold core and the mold frame. In the thickness direction of the mold core, the orthographic projection of the conformal water channel on the mold core covers the surface of the mold core used to form the molding chamber. The injection mold is arranged in a split mode of the mold frame and the mold core. The cooling water channel corresponding to the molding chamber can be arranged on the surface of the mold core according to the size and shape of the molding chamber. The manufacturing difficulty of the conformal water channel is reduced. Since the conformal water channel matches the surface of the mold core used to form the molding chamber, the cooling effect of different positions of the injection product can be kept highly consistent, so that the temperature uniformity is improved.

This utility model discloses a lead cutting and forming device for integrated circuit processing, including a lead cutting assembly and a fixing frame assembly. A processing table component is horizontally mounted directly below the lead cutting assembly, and a material conveying assembly is horizontally mounted directly below the processing table component. The fixing frame assembly is connected to the front and rear ends of the left and right sides of the material conveying assembly. This lead cutting and forming device for integrated circuit processing, by providing fixing frame assemblies at the front and rear ends of both sides of the entire device, provides good structural restraint on both sides of the processing table component to ensure the stability of material processing. It also provides good structural support for the entire device and ensures its structural stability. Furthermore, the structural arrangement of the material conveying assembly in conjunction with the processing table component ensures efficient lead cutting while simultaneously separating material from waste.

This utility model discloses an overhead line safety distance early warning device, including an early warning component and a first fixed base. The bottom of the early warning component is connected to the first fixed base, and a second fixed base is disposed below the first fixed base. A protective cover is provided on the outer side of the early warning component. Fixing screws are vertically inserted through both sides of the first and second fixed bases. This overhead line safety distance early warning device employs a modular structure consisting of six sets of components: the early warning component, the first fixed base, the second fixed base, the protective cover, the fixing screws, and the fixing nuts. This allows for structural adjustments to suit different usage environments and installation needs, ensuring structural stability and operational flexibility. Furthermore, the protective cover provides effective structural protection without affecting the normal operation of the early warning component, thus ensuring the safety of the device.
