Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds and relates to a six-station rotary injection mold for automobile headlight lenses. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. A hot runner pouring mechanism is usually provided in the injection mold, and the plastic melt enters the mold cavity from the nozzle of the injection molding machine through the main runner, branch runner, cold well, and gate. The runner is an important channel from the main runner to the gate, and is the flow channel for the molten plastic ejected from the nozzle of the injection molding machine. The runner should be designed to have low resistance and prevent cooling. Usually the runner is designed to be trapezoidal or circular. The existing automobile headlight lens is composed of six different lenses. Since the polymer chain orientation behavior of each lens is different during injection molding, usually after the mold is opened at the same time, it will cause each lens to fail to meet the standard at the same time, resulting in a low yield rate. Some manufacturers produce each single lens, which will increase the number of molds and increase the manufacturing cost. Therefore, in view of the above problems, a six-station rotary injection mold for automobile headlight lenses is proposed. Utility Model Content
