Description

Medicine box product mould

Technical Field

The utility model relates to the technical field of injection molds, in particular to a medicine box product mold which is used for injection molding of medicine boxes and other multi-grid box body products.

Background

Taking the medicine box as an example, the simple box body comprises a peripheral side wall and a bottom wall, if the interior needs to be divided into cells, the additional paperboard is reused to be separated, the whole body, the structural strength and the partition separation and protection effects on the medicine are considered, and the medicine box is designed into a multi-cell box body plastic product in the future, namely, the box body comprises the peripheral side wall and the bottom wall of the box body and a plurality of partition strips integrally connected inside the box body, so that the box body is divided into a plurality of cell areas.

In the prior art, when injection molding medicine box, no matter be simple box body or many check box body, generally adopt inversion formula, when injection molding product promptly, inside the mould, the diapire of box body is upwards, and the week lateral wall of box body is located the below of diapire, and it advances gluey in medicine box bottom center department, generally is a glue feeding point. For example: CN 211251193U discloses an injection mold for a bottom shell of a medicine box, comprising an upper mold, a lower mold and a top plate arranged between the upper mold and the lower mold, wherein an inner core is arranged between the upper mold, the lower mold and the top plate, a molding cavity matched with the shape of the bottom shell of the medicine box is formed between the inner core and the upper mold, a nozzle communicated with the molding cavity is arranged at the top of the upper mold, an upper panel is arranged at the top of the upper mold, a positioning ring is arranged in the middle of the upper panel, and an injection molding opening communicated with the nozzle is arranged in the positioning ring; the box body is inverted in the die, and the bottom wall is glued at the center of the upper end.
