AI Technical Summary
The existing Haval slider core-pulling mechanism is prone to uneven force on the product during single core-pulling and demolding, which may lead to scratches, deformation and other damage risks, and no pre-separation operation is performed.
A slider core-pulling mechanism in a Haver-type slider was designed. By performing a pre-separation operation before mold closing, the pre-separation and demolding of the product are achieved through the cooperation of the inclined guide rod and the inclined guide groove. The movement of the core-pulling block is assisted by a spring, and the sliding cooperation of the guide block and the guide rail block ensures the stability and accuracy of the slider.
It improves the finished product's appearance quality, reduces the risk of damage during demolding, and increases production efficiency and molding precision.
