How can the trimming die be better?

A smooth positioning of the aluminum alloy die casting die, comprising an upper mold, a lower mold, a guide structure provided between the upper and lower molds, a product positioning structure provided in the lower mold, and a cutting edge edge provided in the upper die The lower part of the fixed plate is provided with a cavity in which the support plate is movable up and down, and the support plate of the product is provided with a return lever and a plurality of support rods for supporting the feed handle, the upper end of the return rod and the support rod And the upper die is slidably connected with the lower die, and the upper mold is provided with a pressing bar at the corresponding return lever position, and a resilient reset element is arranged between the support plate and the lower pressing plate of the lower mold. This product is always cut into the horizontal state of the feed handle, so that after the punching of the product after the incision smooth and tidy; punching at the same time the product was synchronized out to facilitate the product removed, to avoid product surface damage; Convenient, and the guide column is not easy to break.

Trimming die repair and remanufacturing special electrode, the chemical composition of the chemical composition of the weight percentage of wt%: titanium powder 1-3, marble 20-35, fluorite 15-20, quartz 3-5, white earth 2 -4, high-carbon ferrochrome 8-10, high-carbon ferromanganese 2-4, ferrosilicon 2-4, titanium iron 6-8, molybdenum iron 3-5, cerium oxide 4-8, metal nickel 2-4, Vanadium iron 2-4, tungsten iron 3-6, graphite 5-7; its welding core for the H08A steel wire. The use of the welding electrode on the trimming die repair and re-manufacturing before the need for preheating, surfacing after two tempering treatment. The invention is easy to use and easy to weld, improve the impact resistance of surfacing metal, anti-cracking and wear resistance, the hardness of surfacing metal in HRC55-60, the trimming die mold life is longer than the original cutting mold 2-3 times.
