Hex Nut Bulkhead Fittings Mold - Spark Mould
The hexagonal nut is made of nylon + GF. The average thickness of the product is thicker than that of ordinary plastic parts. The mold is a cold runner, with 8 cavities. There are several circles of threads inside the product. In order to eject the product smoothly during the molding process, we use a collapsible core slider mechanism to achieve it. The foldable core is a very representative mold slider mechanism, mainly for the internal thread or annular boss of the plastic part.
Collapsible Slider Core Pulling Mechanism
We designed 7 delicate parts to combine the collapsible core. In this innovative design, the retraction and reset mechanism of the slider becomes the core highlight of the entire system. In the key link of product ejection, the core must first complete the contraction under the guidance of the push plate to create the necessary space conditions for the smooth ejection of the product.
Delayed Ejection Mechanism
During the ejection process, the push plate pushes the movable mold forward a certain distance through the push rod, causing the threaded slider to contract, releasing the product, and then the ejector pin ejects the product.
