the flask of the slip flask injection molding machine is uniformly injected into the flask by using compressed air for pre-compaction, and then external force is applied for compaction, and the common flask injection molding machine is a vertical parting flaskless injection molding machine and a horizontal parting slip flask injection molding machine. The vertical parting flaskless shooting and pressing molding machine does not use a sand box, molding sand is directly shot into a molding chamber with a template, the molding sand has high dimensional precision, and because the two surfaces of the sand box are provided with cavities, the production efficiency is high, but core setting is difficult, and the requirement on the quality of the molding sand is strict. The horizontal parting slip flask injection molding machine utilizes the sand box to mold, and the sand mould causes post-synthesis slip flask, so that core setting is easy, and the production efficiency is high. However, in the horizontal parting and flask-releasing injection molding machine, it is necessary to perform a mutually forced tight squeeze in the horizontal direction on the sand box filled with molding sand, thereby enlarging the mutual association of the molding sand particles in the sand box to form an integral molding sand mass.

The sand box is a forming tool for bearing molding sand and compacting sand mould (casting mould) in the horizontal parting and stripping injection molding machine, and is an essential important component in the whole molding process. The sand box structure of the existing horizontal parting flask-removing injection molding machine is assembled by a plug, a side plate, an exhaust plate and the like. The two plugs and the two side plates form an outer frame of the sand box; four exhaust plates on the inner side are fixed on the plugs and the side plates to form a sand box inner frame; the four exhaust plates form 90-degree included angles with each other on the inner side of the sand box. The sand box with the structure has certain defects, and in the process of stripping after compaction, the formed sand mould module is tightly combined with the sand mould and lacks the space for separating the sand mould from the sand box, so that friction is easily formed between the sand mould and the four walls of the sand box during sand mould separation, and the corner shape of the sand mould module is damaged; meanwhile, the abrasion of the box-removing plate can cause the sand blasting phenomenon in the sand box, the sand blasting can increase the further abrasion of the sand box and the box-removing plate, and the like, and the phenomenon that the box-removing plate is blocked in the box-removing motion process is easily caused, so that the blocking accident of the sand box in the conveying process is caused to influence the whole operation program. The production efficiency of the whole flask-removing injection molding machine is reduced, the molding quality of the molding machine is influenced, the compaction degree of molding sand is also influenced to a certain degree, and the repair and update cost of the sand box is increased.
