Design Key Points of Core-pulling and Slider Mechanisms in Injection Molds

The design of core-pulling and slider mechanisms in injection molds has several important points. Firstly, for the structure layout, the position, number and stroke of the slider should be determined according to the shape and demolding requirements of the plastic part to ensure smooth demolding. Secondly, in terms of guidance design, appropriate guidance methods should be adopted to ensure the smooth movement of the slider and the appropriate fit accuracy. Thirdly, the locking method should be reliable, such as wedge locking, and the locking force should be calculated based on the melt pressure. Fourthly, the cooling system should be reasonable, with the cooling channels close to the molding surface and the cooling medium parameters well controlled. Finally, the slider needs to be closely coordinated with other components. At the parting surface, the accuracy should be ensured, and its movement should be coordinated with the ejection mechanism, thus ensuring the normal operation of the mold and the quality of the plastic part.
