Introduction

In rubber and plastics machinery, the clamping system is often referred to as a quick mold change system. Its core function is to quickly and securely fix the mold onto the rubber substrate.

On the mold plates of plastic machinery. Its emergence was to replace the traditional manual bolt-locking method, thereby significantly shortening mold changeover time and improving efficiency.

High equipment utilization and production response speed, especially suitable for the current demand for multi-variety, small-batch production.

Based on their working principles and power sources, clamping systems are generally classified into mechanical clamping systems, hydraulic clamping systems, pneumatic clamping systems, and...

Magnetic clamping mold system.

Rubber and Plastic Mechanical Clamping System Part 1: Safety Requirements for Magnetic Clamping Systems

1 Scope

This document specifies the design, manufacture, and application of magnetic clamping systems (MCS) for rubber and plastic machinery (such as injection molding machines and flat vulcanizing machines).

It integrates basic security requirements and provides instructions and operational restrictions for safe use.

This document applies to the use of magnetic clamping systems integrated into machines (which use magnetic force to fix the mold to the machine template) and the resulting base this describes the hazards, hazardous conditions, or hazardous events (see Appendix A), and outlines potential misuse during intended use and as reasonably foreseeable by the manufacturer.

In such cases, the requirement is to eliminate or sufficiently reduce the risks associated with these hazards.

This document specifies the requirements for integrating magnetic clamping systems into machines.

This document does not cover hazards associated with rubber and plastics machinery manufacturing processes or other processes (such as horizontal and vertical injection molding processes).

This document does not include hydraulic, pneumatic, or mechanical clamping systems.
