Description

Technical Field

[0001] The utility model relates to the field of molding machines, in particular to a molding machine middle box mechanism with a slide-out structure. Background Art

[0002] In existing sand mold making machines, the mold is usually placed manually in the middle box or screwed into the middle box, upper sand box and lower sand box through a support frame before the sand shooting operation. For example, the mold is placed on the workbench of the molding machine, and then the upper and lower sand boxes are moved to the specified position of the mold. Sand is filled into the mold through processes such as sand shooting and compaction to form the required sand mold; if the mold is not fixed well or the surface is contaminated, it is easy to deviate or tilt, which may affect the quality of the sand mold.

[0003] However, for some larger molds, due to their own weight, they are easy to tilt during placement and are not suitable for manual placement. The screw-in support frame has weak support force and cannot stably support the load of larger molds. At the same time, since the larger molds are taller and the middle box has a certain thickness, it is not convenient to clean the surface if they are directly fixed in the middle box. Therefore, a molding machine middle box mechanism that is convenient for mold fixing and cleaning is needed. Utility Model Content
