Description

Technical Field

[0002] Plastic chairs are produced using the injection molding process. Injection molding is an efficient production method suitable for mass-producing a variety of plastic products. To produce a plastic chair, plastic pellets are first heated to a molten state. Then, an injection molding machine injects the pellets into a mold. As the plastic cools, it solidifies into the shape of the chair. Once cooled, the chair can be removed from the mold.

[0003] Cooling an injection-molded chair is a crucial step in the molding process, directly impacting product quality, production efficiency, and cost. Existing cooling molding devices for chairs require long cooling times during injection molding, extending production time and hindering rapid demolding of the molded chair. To address this issue, we propose a cooling molding device for chairs. Utility Model Content
