AI Technical Summary
Existing pneumatic demolding devices for plastic molds can cause plastic products to stick to the mold due to factors such as rough inner walls of the mold cavity or excessively high mold temperatures. When gas is released rapidly, the ejector pins move too fast, affecting the stable demolding of injection molded products.
A pneumatic demolding device including a sliding frame and a top pressure section was designed. By setting an annular groove and an exhaust hole in the guide hole, the sliding frame rotates in the annular groove to drive the top rod and top plate to move. Combined with a safety valve and magnetic strip structure, stable demolding is achieved.
Even when the molded product is severely adhered to the protrusion, it can still demold quickly and stably, maintaining the integrity of the product to the maximum extent and reducing the positional change of the top plate.
