Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically to a mold which is easy to demould for producing drawers. Background Art

[0002] Plastic storage drawers are common daily necessities and are generally mass-produced using injection molding molds.

[0003] Based on the above, the inventors found that after the drawer is formed, the demolding operation of the traditional molding mold is often cumbersome, and the drawer cannot be conveniently removed from the injection mold, which often causes the drawer to adhere to the upper mold. When the upper mold moves up and separates from the lower mold, the drawer will follow the movement of the upper mold, resulting in the drawer breaking, deformation, etc., which in turn affects the quality of the finished drawer and the production efficiency. Therefore, in view of this, the existing structure is studied and improved, and a molding mold for drawer production is provided, in order to achieve a more practical purpose. Utility Model Content
