AI Technical Summary
Traditional mold structures lead to complex processes, requiring additional cutting and grinding to remove sprues, resulting in low work efficiency. Furthermore, they necessitate the configuration of additional melting tanks, filters, and extruders, leading to cost waste.
A flow distribution structure is formed by using a manifold and a fixed mold cavity plate, eliminating the need for a sprue structure. The manifold directly guides the molten plastic into the mold cavity, ensuring that the molten plastic flows into each mold cavity and preventing leakage. Sealing and positioning structures ensure airtightness.
No subsequent sprue treatment process is required, which significantly shortens the production cycle, improves production efficiency, reduces manufacturing and maintenance costs, and avoids the need for additional equipment.
