Sand box for casting sand mould

Abstract

The invention discloses a sand box for casting a sand mould, and relates to the field of sand mould casting. The sand box for casting the sand mould comprises an upper sand box and a lower sand box which are hollow cuboid shaped bodies, wherein one end of an upper box closing sleeve is arranged at the sidewall of the upper sand box; an upper handle is arranged at the other end of the upper box closing sleeve; one end of a lower box closing sleeve is arranged at the sidewall of the lower sand box, and a lower handle is arranged at the other end of the lower box closing sleeve; an abutting groove which is downwards opened is formed in the lower end surface of the upper box closing sleeve; elastic bumps are welded to two opposite sidewalls of the abutting groove; abutting blocks are arrangedon the upper end surface of the lower box closing sleeve; two opposite grooves are formed in the sidewalls of the abutting blocks; upper box sides are arranged at four edges of an opening of the uppersand box; lower box sides are arranged at four edges of an opening of the lower sand box. According to the sand box for casting the sand mould, a box closing device consisting of the upper sand box sleeve and the lower sand box sleeve can be accurately positioned, and the reliability is high; and meanwhile, mould sand in the sand box can be conveniently fixed, so that the sand mould is preventedfrom moving during releasing a mould or overturning the box, and the upper sand box and the lower sand box can be conveniently hoisted.

Description

technical field [0001] The invention relates to the field of sand casting, in particular to a sand box for sand casting. Background technique [0002] In my country and in the world, most castings are produced by sand casting method. Sand casting refers to the casting method in which molds and sand cores are made of mold (core) sand with certain performance through different compaction methods. It has flexibility. Large, short production cycle, low price and other advantages. [0003] In the sand casting process, the function of the sand box is to put the molding sand into the sand box to form a mold of the required shape. At present, the sand box for sand casting is welded and clamped by wood or steel plates. [0004] The traditional box positioning of the existing sand casting generally adopts the following two methods: [0005] 1. Fix the boxing cone on the board, make positioning holes for boxing on the sand mold, insert sand boxing pins during the boxing process to per...

Problems solved by technology

This method has high dimensional accuracy, but the operation process is complicated and difficult and has high requirements on the size and structure of the sand box, so it is only suitable for production lines with a high degree of mechanization
