AI Technical Summary
When existing injection molding machines remove materials, some injection molded parts are stuck to the inner wall of the mold, making it difficult to remove the parts and causing them to be easily damaged.
The design incorporates components such as double-sided toothed plates, gears, shafts, sprockets, worm gears, and worm wheels. The mounting plate is moved by an electro-hydraulic rod, which in turn moves the ejector plate to push out the injection molded part, avoiding direct contact with the inner wall of the mold.
This effectively avoids direct contact between the injection molded part and the inner wall of the mold during material removal, reducing laborious operation and damage to the injection molded part, and improving the convenience and safety of material removal.
