# Industrial Specification: Mold Box Clamping System

## 1. Technical Definition
A mechanical system that securely holds and aligns the cope and drag mold boxes during the sand molding process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-80 bar hydraulic pressure, 0.02-0.05 mm alignment tolerance, 20-150 kN clamping force**. Failure boundary: **Hydraulic pressure exceeding 85 bar causes seal extrusion, alignment deviation beyond 0.08 mm creates mold mismatch, clamping force below 18 kN allows mold separation during pouring**, Mechanism: **Seal failure occurs via extrusion when hydraulic pressure exceeds the seal material's yield strength (typically 25 MPa for HNBR). Mold mismatch results from cumulative tolerance stack-up exceeding the sand mold's elastic deformation limit (approximately 0.1% strain). Insufficient clamping force allows mold separation when molten metal pressure (approximately 0.2-0.4 MPa) exceeds the friction force between mold halves.**.
