The utility model provides a gate cup, which comprises a cup body composed of sand mould, a metal frame on the outer surface of the cup body, a insulation layer between the cup body and the metal frame, a filter screen between the cup cavity and the gate channel, and a convex baffle around the cup mouth at the upper end of the cup body. The outer side of the frame is provided with a vibrating device and a lifting lug. The beneficial effects of the utility model are as follows: by setting a convex baffle to prevent metal melt splashing and overflow, the convex department can catch foreign impurities, avoid them falling into the casting mould, and improve the casting quality. By setting metal frame, the strength of gate cup can be effectively improved, and the breakage of gate cup can be avoided in the process of pouring. By setting insulating layer, the condensation of molten metal can be prevented and the pouring effect can be improved. By setting vibration device, the metal melt outflow speed can be accelerated, the metal melt loss can be reduced, and the resources can be saved. By setting the lifting lug, it can facilitate the lifting of the pouring cup.

一种浇口杯
本技术涉及铸造加工工具
,特别是指一种浇口杯。
技术介绍
浇口杯是漏斗形的外浇口,其作用是承接来自浇包的金属液,防止飞溅和溢出,方便浇注,能够减少金属液对铸型的直接冲击,提高金属液静压力。传统浇口杯大多由人工临时制作完成,其杯体强度不足,用于大型铸件浇注时,高温金属熔液常常会将杯体砂型击破,导致破碎的砂型杂质随金属熔液进入铸件中,影响铸件品质。传统浇口杯往往由单层砂型构成,保温效果差,在浇注时金属熔液容易被冷却,影响浇注效果。传统浇口杯杯口是敞开式结构,浇注时金属熔液容易溅出,造成工伤事故,且外来杂质颗粒物也容易落入导致铸件夹杂杂质,形成沙眼,影响铸件品质。传统浇口杯在浇注时,往往会有少量金属熔液残留在杯体内,造成浪费。
技术实现思路
