铸件用沙箱
本专利技术涉及一种沙箱,尤其涉及一种铸件用沙箱。
技术介绍
沙箱是铸件成型使用的必备装置,铸造时先将铸件成型模具放置于沙箱内,然后填埋石英沙,倒入熔化好的液体原料,同时通过风道将铸件成型过程中产生的气体抽走,从而实现铸件成型。目前使用的沙箱在箱体外纵横焊接了很多风道,沙箱的结构复杂,设备笨重,耗用材料太多,造价高。
技术实现思路
本专利技术针对不足,提供一种结构简单、造价低廉的铸件用沙箱。本专利技术解决上述技术问题的技术方案如下:一种铸件用沙箱,包括开口向上的箱体,其特征在于,箱体的底壁上面设有吸风管道,吸风管道包括内总风管,内总风管上连通有多根内分支风管,内分支风管上开设有吸风孔;箱体的侧壁上开设有上通孔,上通孔外侧的箱体侧壁密闭固定连接有外风道,外风道密闭连通有外连接管,外连接管与内总风管密闭相通。根据所述的铸件用沙箱,其特征在于,所述内分支风管互相平行设置。根据所述的铸件用沙箱,其特征在于,所述内分支风管外固定连接有遮挡所述吸风孔的滤网。根据所述的铸件用沙箱,其特征在于,所述上通孔沿所述箱体的一周开设。根据所述的铸件用沙箱,其特征在于,所述上通孔内侧的所述箱体的侧壁固定连接有遮挡上通孔的滤网或内挡板,内挡板与箱体的侧壁不连续连接。根据所述的铸件用沙箱,其特征在于,所述内挡板的纵向截面为“〈”型、“[”型或弧形。根据所述的铸件用沙箱,其特征在于,所述箱体的侧壁开设有下通孔,下通孔内侧密闭连通有内连接管,内连接管与所述内总风管密闭相通,下通孔外侧与所述外连接管密闭相通。根据所述的铸件用沙箱,其特征在于,所述箱体的开口端外侧固定连接有加强筋。根据所 ...
