[0002] Injection molds are tools for producing plastic products; they are also tools that give plastic products complete structures and precise dimensions. Injection molds are also a processing method used in mass production of parts, and are mainly used in the industrial field. The injection mold process is to inject the heated and melted material into the mold cavity by high pressure, and after cooling and solidification, a molded product is obtained; according to the molding characteristics, it is divided into thermosetting plastic molds and thermoplastic plastic molds. In the injection molding production process of trash cans, demolding and stacking are crucial and challenging.

[0003] Traditional demoulding operations mainly rely on manual operation, and operators need to spend a lot of physical strength and time to remove the molded trash can from the mold. This not only leads to extremely low production efficiency, but also because it is difficult to accurately control the force and angle of manual operation, it is very easy to cause damage to the appearance and structure of the trash can, such as scratches, deformation, etc., thereby reducing the qualified rate and quality grade of the product. In terms of stacking, it also relies on manual labor to carry and stack the demoulded trash cans one by one. This method is not only labor-intensive, but also difficult to ensure the neatness and stability of stacking.
