Description

Technical Field

[0001] The utility model relates to a mold block, in particular to a mold block of a packing box pressing mechanism. Background Art

[0002] Packing boxes are mainly for facilitating transportation, loading and unloading, and storage. Generally, wooden boxes and corrugated solid wood pallets are used, and sometimes tin barrels or galvanized iron barrels are also used. The standard adopted is GB / T 7284-1998, the drafting unit of the national standard for framed wooden boxes. According to the characteristics of the items to be transported or loaded, national standards are adopted for protection.

[0003] The mold block of the packing box pressing mechanism mentioned in the Chinese utility model patent CN204096237U includes a body, a clamping block and a magnetic block. The clamping block is arranged at the upper end of the body, and the magnetic block is embedded in the lower end surface of the body. There is a convex strip folded at a right angle on the lower end surface of the body, which solves the problem that the magnetic force of a single magnetic block cannot ensure the stability of the square iron piece during the downward stroke of the packing box pressing mechanism. Often, the square iron piece will move relative to the lower end surface of the mold block, resulting in a poor fixing effect between the stamped square iron piece and the wooden board, and a poor suction stability of the mold block.

[0004] Referring to the above patent, it can be seen that during the use of the mold block, the bottom end of the mold block is mostly adsorbed to the square iron piece through a magnet, the adsorption effect is not ideal, and there is a lack of an auxiliary limiting function for the square iron piece. It is easy to occur a misalignment situation between the mold block and the square iron piece during the stamping process driven by the mold block, which affects the fixing position of the square iron piece and the template.

[0033] Specifically, during the installation of the mold block body 1, the mold block body 1 is placed at the bottom end of the lower pressing block 14 of the pressing mechanism. The bottom end of the limiting block 6 is snap-fitted with the limiting groove 3 opened on the bottom side surface of the mold block body 1. Rotate the limiting bolt 7, and the end of the limiting bolt 7 penetrates through the limiting block 6 and is threadedly connected to the bottom side surface of the lower pressing block 14 of the pressing mechanism, realizing the stable fixation of the mold block body 1.
