Description

TECHNICAL FIELD

[0001] The utility model relates to foundry tool technical field, in particular to a sand box with variable box stop. BACKGROUND

[0002] The sand box is an important tooling setting for casting, which is composed of a sand box body and a box stop arranged at one side opening. The traditional box stop includes longitudinal and transverse box stops, which are staggered at the opening of the sand box to strengthen the sand mold. When the sand mold is cast by the sand box, the sand box is first placed on the bottom mold (the bottom mold is a model with a pouring system, a casting outer mold and corresponding risers), the opening of the sand box with the box stop faces upward, then the sand box is filled with sand, and the sand is waited to be bonded into a whole, then the sand box is turned over, the position of the sand box and the bottom mold is reversed, and finally the mold is removed to obtain the sand mold.

[0003] When the sand box is placed on the bottom mold, the box stop may conflict with the structure of the bottom mold. At this time, the box stop needs to be cut and welded to adapt to the structure of the bottom mold, which consumes a lot of labor and material costs. The prior art designs a detachable sand box stop belt to replace the original longitudinal and transverse designed box stop, and corresponding mounting holes are machined on the opposite sides of the upper opening of the sand box. A plurality of sand box stop belts are installed between the mounting holes on the two sides. The main body of the sand box stop belt is formed by pasting or embedding two parts. The left and right parts are locked to form a longitudinal box stop through the transverse box stop (movable box belt). This box stop structure can be disassembled and adjusted according to the structure of the bottom mold during molding. The position of the transverse box stop (movable box belt) is very flexible, and there is no need for cutting and welding, which saves costs. The disadvantage is that the main body of the sand box stop belt is formed by pasting or embedding two parts, which makes the structure complex, and multiple people are needed to lock during installation. The accuracy of the alignment of the left and right parts cannot be guaranteed during the locking process. The transverse box stop completely relies on a single longitudinal box stop after locking. The stability and strength of the box stop structure are insufficient due to the excessive pursuit of flexibility. After the sand box is removed, the inside of the sand box needs to be cleaned to remove residual sand, binder and other substances for reuse. However, the sand box stop belt has many sliding grooves, which consumes a lot of time for cleaning. If the cleaning is not done properly, it will affect the connection of the structure during reuse, and the alignment accuracy will be reduced again.

[0004] Therefore, it is necessary to improve the prior art. UTILITY MODEL CONTENTS
