[0004] In order to solve the above technical problems, the technical solution of the utility model is: a mold structure for preventing loose box closing and casting shot box, the innovation of which is that it includes a template module and a sand box module;

[0005] The template module includes a supporting base frame and a template unit; the supporting base frame is a rectangular shell structure surrounded by four plates; the template unit is horizontally arranged on the top of the supporting base frame; lifting strips are provided at the corner positions of the upper surface of the template unit; and a sand mold is provided at the middle position of the upper surface of the template unit;

[0006] The sand box module cover is buckled on the mold plate unit, and the end corners of the sand box module are placed on the lifting spacer, leaving a gap between the bottom end of the sand box module and the mold plate module; the inner cavity of the sand box module cooperates with the outer contour of the sand mold to form a sand cavity; a sand injection port is provided on the sand box module, and sand is injected into the sand cavity through the sand injection port to realize the molding of the sand.

[0007] Furthermore, handles are provided on the side surfaces of the supporting bottom frame and the side surfaces of the flask module, and the flask module and the template module can be turned upside down by lifting the handles.

[0008] Furthermore, the height of the lifting spacer is 2 mm, and the lifting spacer is arranged at a 45° chamfer direction at the upper corner position on the upper surface of the mold plate unit, so that the end corner of the bottom end of the sand box module is placed above the lifting spacer to form overflow sand with a height of 2 mm. Before the sand box is closed, a scraper is used to scrape off the overflow sand.

[0009] The advantages of the present invention are:

[0010] 1) In the present invention, a lifting strip is provided on the mold plate unit, and a gap is left between the bottom of the sand box and the molding sand when the molding sand is formed. The molding sand will fall directly onto the mold plate unit, thereby ensuring that the end corners of the sand box can also be densely filled with molding sand, avoiding the loose molding sand. In the subsequent box closing process, the excess overflowing molding sand is scraped off with a scraper, and then the boxes are closed. This can ensure the sealing effect at the closing position of the sand box, and also reduce the situation where the end corners of the molding sand are loose and cause the box to be shot.
