Detailed Introduction
This multi-plate mold base consists of fixed plate, cavity plate, core plate, ejector plate and base plate, forming a complete standard mold frame without built-in cavity inserts, allowing customers to install self-designed connector or plastic part forming inserts flexibly.
- Safety & Limit Structure A red micro travel limit switch is mounted on the top edge of the mold plate, which feeds back mold opening/closing position signals to the injection machine for automatic safety interlock; the red mechanical stop block on the side limits maximum mold opening stroke to avoid damage to slide components and ejector pins during unmanned production.
- Cooling System Two blue brass water pipe connectors are reserved on the side of the mold frame, connected to internal drilled conformal cooling circuits inside cavity and core plates, realizing fast heat exchange to stabilize product shrinkage and shorten molding cycle.
- Positioning & Assembly Design Multiple standardized mounting holes, guide sleeve holes and ejector pin holes are pre-machined on each plate, with high parallelism and flatness after precision grinding to eliminate mold offset and flash under high injection pressure. Two metal nameplates with engraved mold serial numbers and technical parameters are attached for production traceability and management.
- Material & Manufacturing Process The mold base frame is made of S50C medium carbon steel with stress relief annealing to eliminate internal processing stress and prevent long-term deformation. All plate surfaces are precision flat grinded to ensure parallelism. Customers can match different corrosion-resistant, high-polish insert steels according to their plastic materials (LCP, PA66, PBT, PEEK etc.).
All mold plates pass three-coordinate flatness and parallelism inspection before delivery. We provide fully customized mold base size, plate thickness, cooling layout and ejection stroke according to customer insert drawings, widely applicable for connector, consumer electronics and automotive small plastic part molds.
