Abstract

The invention belongs to the technical field of lost foam casting, and particularly relates to a lost foam casting sand box. The lost foam casting sand box comprises a sand box body, and the sand boxbody is of a hollow structure and is used for containing a mold. The sand box body comprises a box body and a box bottom. The box body is composed of a first main plate and a second main plate, and the first main plate and the second main plate are connected through a connecting module. The connecting module comprises a first connecting plate and a second connecting plate. One end of the first connecting plate and one end of the second connecting plate are hinged, the other end of the first connecting plate is hinged to the first main plate, and the other end of the second connecting plate ishinged to the second main plate. According to the lost foam casting sand box, by means of cooperative use of the first main plate, the second main plate and the connecting module, the sand box body can be expanded and contracted, the length of the sand box body can be increased through the first connecting plate and the second connecting plate, and therefore the sand box body is suitable for castings of different lengths, widths and heights, and the application range of the sand box body to multiple kinds of castings is widened.

Description

technical field [0001] The invention belongs to the technical field of lost foam casting, in particular to a lost foam casting sand box. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Down pouring, the model is vaporized, the liquid metal occupies the position of the model, solidified and cooled to form a new casting method. When casting castings, it is necessary to use a sand box for work. However, when the sand box is in use, different sizes of the castings require the use of sand boxes of different sizes, which causes inconvenience in use and reduces work efficiency. [0003] There are also some technical solutions for lost foam casting in the prior art. For example, a Chinese patent with application number 2018102228097 discloses a lo...
