The utility model relates to a die -casting die, including the die, be provided with the first core -pulling rod that is connected with the core in the die, still be provided with the pin or second core -pulling rod that is arranged with the first core -pulling rod crossing, its characterized in that: first core -pulling rod is provided with the passageway that is set for the pin or second core -pulling rod to wear, the utility model discloses a passageway is set for the pin or second core -pulling rod to wear on the first core -pulling rod, in the die -casting process, the pin or second core -pulling rod can first move along the passageway to the outside, subsequently first core -pulling rod moves to the outside and will take out the core, to realize the forming of hole structure, and there is no interference between first core -pulling rod and second core -pulling rod or between first core -pulling rod and pin, thereby can realize smooth stripping and punching.

This invention relates to the field of aerogel composite materials technology, and more specifically, to C / SiC foam-reinforced SiC aerogel composite materials and their preparation methods. This invention uses lightweight, high-strength C foam as the skeleton material for the aerogel composite material, and achieves mechanical modification and reinforcement of the C foam skeleton through a SiC coating. The SiC aerogel is obtained by in-situ molding on the surface of the C / SiC foam skeleton using a sol-gel process combined with a carbothermal reduction process, achieving integral molding of the aerogel composite material. Through a gradient structure design, the precursor organic sol solution can better penetrate into the pores of the C foam skeleton. Simultaneously, the porosity can be adjusted to control the proportion of SiC aerogel, optimizing impedance matching characteristics and facilitating surface electromagnetic wave incidence. Furthermore, the internal C foam skeleton also exhibits a gradient distribution, optimizing dielectric loss attenuation and facilitating incident electromagnetic wave absorption, thus synergistically achieving the wave absorption performance of the aerogel composite material.

This utility model discloses a device for extruding and forming utility pole clamps, comprising: an extrusion table; a hydraulic cylinder fixedly connected to one rear end of the upper surface of the extrusion table; a solid clamp module fixedly connected to the extended end of the hydraulic cylinder; a groove formed on one side of the middle of the extrusion table; a roller slidingly fitted inside the groove; a movable frame rotatably connected to the top of the roller; a threaded block fixedly connected to the rear end of the movable frame; a bidirectional screw threadedly connected inside the threaded block; a fixed plate fixedly connected to the middle of one side of the extrusion table; and a fixed sleeve fixedly connected to the upper surface of the fixed plate. The solid clamp module enables the forming of the clamp structure. After forming, the hydraulic cylinder resets, the electric push rod extends and pushes out, and the small motor inside the fixed sleeve drives it again, causing the threaded sleeve to extend. The formed clamp is then pushed out of the extrusion table by the push rod, completing the forming process.
