AI Technical Summary
In the existing technology, when plastic products are foamed and molded, parting lines are formed at the mold closing surface, which makes it difficult to trim the edges of quadrilateral plastic products. Moreover, the existing equipment has poor adaptability and is prone to problems of missing or over-trimming.
Employing a movable seat, tracing structure, and angle locking components, and combining segmented temperature control mode and rapid cooling system with a trimming machine, it achieves an efficient integration of injection molding and trimming, precisely trimming and collecting trimming waste for secondary molding.
It enables precise trimming of quadrilateral plastic products, is highly adaptable, reduces operational difficulty, and allows waste materials to be recycled, thus avoiding resource waste and environmental pollution.
