Transport Lock for Ejector Sets – Secure and Simple Protection for Mould Movement

A transport lock is a specialised safety component designed to secure the ejector set of an injection mould during transport and handling. Its primary purpose is to prevent unintentional movement of the ejector system, which can lead to mechanical shocks, vibrations and potential damage to high-precision tooling components. Transport locks also reduce the risk of injury during mould handling and storage. 

Core Function and Design

The KNARR transport lock is engineered as a simple yet effective device that clamps the ejector set in place while the mould is moved or relocated. The mechanism maintains the ejector position, stopping internal movement that can compromise tool alignment or wear critical surfaces prematurely. This ensures both the mould and ejector components remain protected from unforeseen forces. 

Versions and Material Options

KNARR offers transport locks in different configurations to suit various production environments. A stainless-steel version is ideal for cleanroom applications where corrosion resistance and cleanliness are essential. An alternative version with a red powder coating serves as a high-visibility, safety-relevant option that helps flag locked components. Both options are available in multiple widths to match different ejector set dimensions. 

Installation and Adjustment Features

Installing the transport lock is straightforward and space-efficient: the device mounts via risers on the mould base. A recess is cut at the proper height to align with the ejector set, and a slotted hole allows adjustment between injection and transport positions. A simple screw secures the lock in place, and the recessed design enables easy finger adjustment or use of an Allen key for secure fitting. 

Benefits for Tooling Safety and Longevity

By fixing the ejector set during transport, the transport lock significantly reduces the risk of accidental movements that can cause wear, alignment shifts, or damage to delicate tooling elements. This helps preserve tooling accuracy, lowers maintenance needs, and enhances reliability throughout mould life and through frequent handling or shipping cycles.
