AI Technical Summary
When demolding existing plastic molds, the workpiece tends to stick to the upper mold, which lacks a demolding structure, making it difficult to demold quickly.
The upper sliding plate, upper spring, upper ejector rod, and lower sliding plate are combined in a structure. The upper mold is driven to move by a hydraulic rod. When the upper sliding plate contacts the lower sliding plate, the upper sliding plate cooperates with the lower sliding plate. When the upper mold moves, the upper sliding plate separates from the upper mold, and the upper ejector rod disengages from the lower mold. The lower sliding plate and the lower ejector rod are then driven to move upward by the traction rod, achieving rapid demolding.
This reduces the probability of the workpiece getting stuck on the upper mold, enabling a fast and smooth demolding process.
