Abstract
The utility model provides a thread core-pulling and demoulding device nesting an internal thread product injection mold. The thread core-pulling and demoulding device nesting the internal thread product injection mold comprises a core pin rotating shaft (1), an A gear (13), a rotary sleeve (15), a B gear (2), a drive shaft (3), a driven chain wheel (4), an oil motor (5), a drive chain wheel (6) and a chain (7). The thread core-pulling and demoulding device nesting the internal thread product injection mold adopts a technical scheme that a thread core first slides out of a moving model cavity following a product, the oil motor drives the drive chain wheel to drive the driven chain wheel, the B gear and the A gear through the chain, the driven chain wheel, the B gear and the A gear further drive the core pin rotating shaft to rotate, the thread core on the top of the core pin rotating shaft rotates and looses core from an inner-sleeved internal thread of the product, and then using elasticity of the product, a fixed model push plate pushes out the product and the outer-sleeved internal thread forcibly from a fixed model core. First the inner-sleeved internal thread is rotated and the core is loosened, and then the outer-sleeved internal thread is forcibly taken off, and therefore nested internal thread product injection molding production can get rid of drawbacks of installing and taking movable embedded core artificially, and the thread core-pulling and demoulding device nesting the internal thread product injection mold has the advantages of lightening work load, improving production efficiency, lowering cost and fit for mass production.
