Molding processing system for circular sheet-iron packaging box

Abstract

The invention relates to the technical field of production of packaging boxes, in particular to a molding processing system for a circular sheet-iron packaging box. The molding processing system comprises a base, wherein a hollow cavity is formed in the upper surface of the base; a molding die for molding the circular sheet-iron packaging box is mounted in the hollow cavity; a square hole which is matched with a positioning sleeve is formed in one side of the interior of the hollow cavity; a rectangular block which is adhered to the inner wall of the square hole is mounted in the square hole; a pin hole is formed in one side of the rectangular block; a pin column is fixed into the pin hole; an annular groove which is concentric to the square hole is formed in one side, deviated from the positioning sleeve, of the square hole; and a rubber sleeve is pasted to the inner surface of the annular groove through glue. Compared with the prior art, the molding processing system disclosed by the invention has the following benefits that through a mutual cooperation way of the pin column and the positioning sleeve, fixing of the position of the molding die is realized; and compared with a bolt connection way, the situation of damage of screw holes is avoided, the situation of replacement of the whole base is avoided, and waste of resources is reduced.

Description

technical field [0001] The invention relates to a forming and processing system for a circular tin packaging box, which belongs to the technical field of packaging box production. Background technique [0002] As one of the daily necessities, metal packaging boxes have been widely used for a long time. In a common packaging box, such as a round or oval tin box for storing moon cakes or biscuits, the lid is directly fastened to the box body. At present, round iron packaging boxes are generally formed by extrusion. In order to facilitate the replacement of the forming die, the forming die is usually installed on the base with bolts. However, during the frequent replacement of the forming die, the screw holes that match the bolts are easily damaged If it is damaged due to wrong wires or other reasons, the entire base needs to be replaced, and the replacement cost is high, which increases the waste of resources. Contents of the invention [0003] Aiming at the deficiencies i...
