Abstract

The invention belongs to the field of injection molding equipment and discloses an injection molding device capable of conducting even cooling. The injection molding device comprises a die. A cooling cavity, a containing cavity and a power cavity which are concentric and are in a ring shape are sequentially formed in the side wall of the die from interior to exterior. A storage barrel is arranged above an inner cavity of the die. A discharging valve is arranged at the bottom end of the storage barrel. A first piston is arranged in the storage barrel, and a first piston rod is arranged at the upper end of the first piston. The upper end of the containing cavity is provided with a ring-shaped liquid storage box, and multiple pressure valves are arranged between the liquid storage cavity and the containing cavity. Multiple capillary holes are evenly distributed in the side wall between the containing cavity and the cooling cavity. A ring-shaped second piston is arranged in the power cavity, and multiple piston rods are arranged at the upper end of the second piston. A lever is arranged between each second piston rod and the first piston rod. A through groove is formed in the lower portion of the side wall between the containing cavity and the power cavity. The injection molding device solves the problems that when an existing injection molding device is used for cooling forming, cooling is not even, and consequently the quality of formed products is poor.

Description

technical field [0001] The invention belongs to the field of injection molding equipment, in particular to an injection molding device capable of uniform cooling. Background technique [0002] Injection molding refers to a molding process in which plastic melt is injected into a mold and then cooled and formed. Existing injection molding devices usually include a mold and an injection storage device. In order to facilitate cooling and enhance the cooling effect, a cavity is usually provided in the side wall of the mold for injecting cooling liquid. [0003] When performing injection cooling molding, the cavity is filled with cooling liquid first, and then the plastic melt is injected into the mold to realize cooling molding. However, when this form of cooling molding is adopted, the plastic melt injected into the mold will be cooled first, and the volume of the plastic melt will shrink when it cools, which will cause a gap to form between the lower plastic and the side wall...
