Description

Technical Field

[0001] The utility model belongs to the technical field of pouring mechanisms, and relates to a pouring mechanism for an oblique pouring hot runner of a 32-cavity inspection test tube injection mold. 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. When the existing pouring mechanism is designed inside the injection mold, it is usually poured directly from the middle, and then the flow is diverted at a right angle to the top of the hot nozzle, thereby increasing the length of the runner.
