AI Technical Summary
In existing technologies, when plastic mold products have two different directions of undercutting, the hydraulic cylinder core-pulling structure is unstable, resulting in flash and step difference in the product, and the cost is high. There is an urgent need for a demolding solution that is structurally stable, easy to assemble and disassemble, and has a lower cost.
The design employs a double-layer slider structure, with slider one and slider two featuring a delay structure. This allows slider one to open the mold first, followed by simultaneous demolding of both slider one and slider two. Demolding in two directions is achieved through the drive of the inclined guide pillars, avoiding the need for hydraulic cylinder core pulling.
It achieves a stable demolding process, avoids core pulling and retraction, reduces mold production and maintenance costs, and improves production stability and equipment utilization.
