The utility model provides a sand dewaxing tank, which includes a dewaxing pool, which is characterized by a sand pool on one side of the dewaxing pool, the bottom of the sand pool lower than the bottom of the dewaxing pool, and two steam pipes in the bottom of the vertical sand pool on the vertical side of the dewaxing pool, a steam separator above the steam pipe, and the air blowhole on the steam separator. There is a V shaped sanding plate between the steam baffles, the steam baffle and the sanding plate are formed one in one, and a dewaxing frame is set above the sanding plate, the mold shell is placed in the dewaxing frame, the sand separation plate is inclined along the steam pipe, and the lowest end of the sand separation plate is located at the bottom of the center line of the wall of the dewaxing pool and the sand pool, and the sand separation plate and dewaxing board. The wall ends of the pool are closed, and the wall face of the dewaxing pool and the sand pool is opened with a triangular overflow. The closed plate is arranged on the wall of the sand pool above the overflow mouth, and the closing plate can move up and down to open and close the overflow. The utility model can prevent sand from entering the mold shell, and is easy to remove sand from the bottom of the sink.

一种防砂脱蜡槽
本技术涉及铸造领域,具体涉及一种防砂脱蜡槽。
技术介绍
在失蜡熔模铸造中,需要将数层浆料和砂子附着在焊接好的蜡模树组上制成模壳,然后模壳放入装着热水的脱蜡槽中,热水完全覆盖模壳。由于蜡模树组熔点较低且密度大大低于水,在热水中慢慢融化成蜡液后漂浮在水面,待蜡模完全融化后,取出型壳,便得到浇注所需的型壳。常规的脱蜡槽底部设有蒸汽管,蒸汽管上设有若干蒸汽孔,在脱蜡的过程中,脱蜡水被通过蒸汽孔通入的蒸汽加热,这过程中会形成大量气泡,使落在槽底的砂子随之翻腾,落入型壳中,从而给铸件带来夹砂等缺陷,而且,随着时间增长,槽中的砂子越积越多,砂子的清理也是一个很麻烦的工作。
技术实现思路
本技术提供一种防砂脱蜡槽,旨在解决模壳脱蜡过程中砂子易进入模壳和脱蜡池中砂子的清除的技术问题。为了实现本技术的目的,拟采用以下技术方案:一种防砂脱蜡槽,包括脱蜡池,其特征于:脱蜡池一侧设置有积砂池,积砂池底面低于脱蜡池底面,脱蜡池垂直积砂池方向两侧底部对称设置有两根蒸汽管,蒸汽管上方设置有蒸汽隔板,蒸汽隔板上开有通气孔,蒸汽隔板之间设置有成V形的隔砂板,蒸汽隔板与隔砂板为一体成型,隔砂板上方设置有脱蜡框,脱蜡框内放置有模壳,隔砂板沿蒸汽管方向为倾斜的,隔砂板最低端位于脱蜡池与积砂池连接处壁面中心线最底部,隔砂板与脱蜡池两端壁面封闭连接,脱蜡池与积砂池连接处壁面开设有三角形的溢流口,溢流口上方积砂池一端的壁面上设置有关闭板,关闭板可上下移动打开和关闭溢流口。进一步优选的,所述积砂池底面比脱蜡池底面低50~100mm。进一步优选的,所述通气孔的孔径为10~15mm。进一步优选的,所述 ...
