How to Remove Lower Mold | AIRAYS RSC‑800‑500 All‑Servo Cup‑making Thermoforming Machine

This official technical operation video illustrates the complete standard workflow for lower mold removal of AIRAYS RSC‑800‑500 all‑servo cup‑making thermoforming machine. This positive‑pressure forming equipment is designed for mass‑production of disposable beverage cups, coffee cups, milk cups, food bowls and diverse plastic food containers. It supports multiple sheet raw materials including A‑PET, R‑PET, C‑PET, BOPS, HIPS, PP, PLA, PVC and barrier materials to satisfy various food‑packaging manufacturing scenarios.

Lower mold bears the core forming cavity for cup‑style products. Non‑standard disassembly operations may cause mold cavity scratch, thread damage, mold drop‑off hazard or collision to machine structural components. All disassembly work must be completed by well‑trained and qualified service technicians. Strict lock‑out‑tag‑out safety procedure shall be implemented before any operation. Cut off main power supply, shut down air source, and confirm all moving components have come to a full stop to avoid accidental machine movement.

Wait until lower mold cooling‑water pipeline and mold body cool down to ambient temperature to prevent scald injury. Drain residual cooling water inside mold channels, blow pipeline inner residue clean with compressed air, then disconnect cooling‑water quick‑connect joints. Prepare hoisting tools, protective cushion blocks and torque tools in advance. Clear surrounding workspace to guarantee enough operating space for hoisting movement.

Access lower‑mold mounting bolts, loosen each bolt gradually following reverse cross‑diagonal sequence. Do not fully take out all bolts at one time, keep partial bolts temporarily installed to support mold weight and prevent sudden slipping. After all mounting bolts are completely removed, connect hoisting fixture onto lower mold lifting lugs, keep hoisting rope steadily under slight tension to bear mold weight. Take away remaining temporary support bolts slowly.

Lift lower mold slowly and vertically, avoid tilt, swing or scraping against machine platen and guide components. Place disassembled lower mold onto soft protective cushion blocks. Inspect mold cavity surface, locating pins, cooling channels and thread holes after disassembly. Apply anti‑rust agent on forming surface for long‑term mold storage.

This machine adopts four‑column plus five‑point structural connecting‑rod mechanism and quick‑change mold system. Following standardized removal steps protects mold precision and machine frame, extending service life of both equipment and molds. Never use prying tool to force‑strip mold to avoid permanent deformation.
