Pascal auto coupler
Overview
This document details technical specifications, configurations, and best practices for auto coupler modules and connectors used in injection molding machines (IMM) and related industrial machinery. It covers hydraulic, water, air, electric, and vacuum connections, emphasizing modularity, reliability, and compatibility to support efficient mold changes and machine operations.
1. Coupler Module Types and Mounting Methods
- Screw Mounting: Standard couplers sized 1/4" to 3/4" for hydraulic, water, and air connections.
- Flange Mounting: Available in standard and large flow variants with port sizes up to 2", designed for higher flow demands.
- Embedded Type: Compact couplers for 1/4" water and air connections without pressure maintenance capability.
2. Materials and Construction
- Coupler bodies are made from stainless steel, chromium molybdenum steel, or copper alloy, chosen for durability and corrosion resistance, especially for water and air applications.
3. Coupling Systems and Clamps
- Pascal Coupling System: Supports hydraulic and magnetic clamps with horizontal load capacities up to 45,000 kN (4,500 tons).
- Integrated self-alignment mechanisms and lock guide sockets/pins ensure precise, secure mechanical connections.
4. Connection Ports and Fluid Types
- Port sizes range from 1/8" to 2", tailored to fluid type and flow requirements.
- Supported fluids include general mineral-based hydraulic oil, water, air, and vacuum.
- Electric connectors vary from 6 to 145 pins, including power connectors rated up to 40A.
5. Dimensions and Configurations
- Couplers for machine and mold sides have specified widths and heights (e.g., fixed platen widths from 125 mm to 775 mm, heights from 45 mm to 925 mm), excluding brackets.
- Configurations cover fixed platen, movable platen, mold side, and machine side couplers with detailed port counts and sizes.
6. Application Examples and Load Capacities
- Designed for IMM capacities from 1,000 kN to 45,000 kN, including die casting machines, magnetic clamps, and mold changers.
- Port and connector arrangements are tailored to specific machine functions and tonnage.
7. Electric Connectors and Mechanical Components
- Power connectors rated at 40A with 3 pins; signal connectors up to 200 pins rated at 23A.
- Electric connectors are typically mounted on trestle or machine bottom surfaces.
- Lock guide pins and sockets with self-alignment mechanisms ensure reliable mating between machine components.
- Trestle dimensions examples: 450×125 mm and 410×120 mm.
8. Fluid Connections and Port Configurations
- Port sizes include 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1 1/4", 1 1/2", and 2".
- Examples: Water 3/4" × 4 ports; Water and air 3/8" × 10 ports plus 3/4" × 2-3 ports; Vacuum Rc3/8" × 4 ports; Large scale water and air Rc1/4" × 50 ports.
9. Key Features and Best Practices
- Self-alignment mechanisms reduce setup time and improve connection reliability.
- Lock guide pins and sockets secure mechanical alignment during coupling.
- Multi-fluid and electric connections integrated into single units optimize space and simplify mold changes.
- Material and port size selection must match fluid type and pressure to ensure safety and performance.
- Use of check valve couplers recommended for temperature control and air valve gate applications to prevent backflow.
- Dimension specifications exclude brackets and must be verified for installation compatibility.
10. Summary Table Highlights
The document includes detailed tables summarizing component dimensions, connection types, pin/port counts, current ratings, and notes on mounting and locking features. Key data include:
- Electric connectors: Widths 230–920 mm, heights 120–204 mm, pin counts from 3 (power) to 200 (signal), current ratings 18A–40A.
- Water and air ports: Multiple configurations with up to 50 ports for large-scale applications.
- Vacuum ports: Rc3/8" with 4 ports, integrated with lock guides and self-alignment.
Conclusion
This comprehensive technical reference supports the selection and configuration of auto coupler modules and connectors for injection molding and related industrial machinery. It highlights modular design, safety features such as self-alignment and lock guides, and the importance of matching port sizes and fluid types to machine requirements. The data facilitate efficient, safe mold changes and reliable machine operation across a broad range of tonnages and applications.
