Smelting and pouring fixture

熔炼浇注治具

Abstract

The utility model discloses a smelting and pouring fixture. The smelting and pouring fixture comprises a base and a mesh cooling water pipe frame positioned on the base, wherein metal melt after smelting is poured into each grid defined by the mesh cooling water pipe frame. In order to further improve the cooling speed, an interlayer cooling water jacket is also arranged at the outer periphery of the cooling water pipe frame. The heat in the metal melt is taken away by the cooling water which continuously flows in the cooling water pipe frame and the interlayer cooling water jacket, so that the metal melt is quickly cooled, and is quickly cured and formed, segregation is reduced, the metal activity is quickly reduced, the combination between the metal melt and nitride in air is reduced, and the good rate of molded products is improved. According to the smelting and pouring fixture, the cooling of the metal melt is accelerated by flowing cooling water serving as a medium, so that the product defects caused by low cooling speed in the prior art are overcome, the product can be molded in one step according to requirements without procedures of pouring and molding large blocks and then manually crushing the large blocks according to required sizes, and manpower and materials are saved.
本实用新型公开了一种熔炼浇注治具,包括底座和位于底座上的网状冷却水管架,熔炼后的金属熔融体浇注于网状冷却水管架围成的各网格中。为了进一步提高冷却速度,在冷却水管架的外围还设置有夹层冷却水套。通过冷却水管架和夹层冷却水套中不断流动的冷却水将金属熔融体中的热量带走,使其快速冷却,快速固化成型,减少偏析,快速降低金属活性,降低与空气中氮的结合,提高成型产品的优良率。本实用新型通过流动的冷却水作为介质来加速金属熔融体的冷却,解决了现有技术因冷却速度慢所带来的产品缺陷,达到产品可根据要求一次成型到位,无需先大块浇注成型,然后通过人工按要求尺寸破碎,节约人力物力。
