Hexagonal thread connector mold - Spark Mould
This is a very unique hexagonal thread connector mold. Because there are two discontinuous threads inside the connector, the product height is 110mm. The two threads have opposite rotation directions, so two independent unscrewing mechanisms are required, which are set on the movable mold and the fixed mold respectively.
Automatic unscrewing thread mold mechanism
During the injection molding process, the plastic part will be tightly wrapped around the threaded core of the mold after cooling and finalizing. The function of the automatic thread removal mechanism is to separate the threaded core from the plastic part through a specific mechanical movement when the mold is opened. This prevents the plastic part from being difficult to ejection due to the threaded structure, ensuring the continuity of production and the integrity of the product.
Hydraulic cylinders are set on different sides of the movable mold and the fixed mold to drive the unscrewing thread mechanism. Because the mold has 4 cavities, each set of mechanisms consists of 8 sets of gears and bearings.
