AI Technical Summary
Technical Problem
Existing injection molds cannot effectively clean the inside of the molding cavity during the mold closing process, resulting in the residue of plastic debris, dust and other impurities, which affects product quality.
Method used
An injection mold with a dust collection component and a moving component was designed. The molding cavity is cleaned by air jetting through a nozzle, and the dust collection component is used to remove dust, ensuring that the molding cavity is thoroughly cleaned before mold closing.
Benefits of technology
It effectively removes impurities from the molding cavity, prevents impurities from embedding in the product surface, improves product appearance quality, and reduces the defect rate.

Abstract
The utility model discloses an injection mold for processing a plastic packaging box, which belongs to the technical field of packaging box production and comprises a lower mold block, an upper mold block is arranged above the lower mold block, a forming cavity is arranged in the lower mold block, a row of nozzles are arranged on each of two sides in the upper mold block, and the nozzles on two sides are connected through a hollow pipe. First piston rods are arranged at the two ends of the bottom of the upper module, connecting pipes communicating with the two nozzles are arranged at the tops of the two first piston rods correspondingly, the two first piston rods are slidably connected to the two ends in the lower module correspondingly, and second piston rods are arranged at the two ends of the bottom in the lower module correspondingly; the two second piston rods are slidably connected to the interiors of the two first piston rods correspondingly, the upper die block is close to the lower die block, air in the first piston rods is extruded into the nozzles, the effect of cleaning the interior of the forming cavity is achieved, it is ensured that cleaning of the forming cavity is completed before melt injection, and the forming efficiency is improved. And the impurities are prevented from falling into the forming cavity again from a gap after cleaning and before mold closing.
