Technical Field

[0001] This utility model belongs to the field of plastic technology, and in particular relates to an automatic control system for drip molding and bottom pouring. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. Current mainstream molding technologies include injection molding and drip molding.

[0003] Drip molding technology utilizes the variable state property of thermoplastic polymers—that is, they exhibit viscous flow under certain conditions and can revert to a solid state at room temperature. Using appropriate methods and specialized tools, ink is sprayed into the desired shape in its viscous flow state, and then cured at room temperature. Drip molding is widely used in the decoration of various trademarks, nameplates, cards, daily hardware products, tourist souvenir badges, fine handicrafts, and high-end notebook covers.

[0004] In traditional production lines, the drip molding and bottom-pouring processes usually rely on manual operation or semi-automatic equipment, and different processes cannot be produced continuously, resulting in problems such as high labor costs, low production efficiency, and unstable quality.
