DIN Z051 Round Taper Interlocks | Precision Locating Units for Injection Molds

Product Overview

DIN Z051 round taper interlocks are precision locating units used in plastic injection moulds to ensure accurate alignment between core and cavity plates during mould closing. These components are designed to absorb lateral forces, protect parting surfaces, and maintain stable mould positioning under high clamping pressure and repeated production cycles.

Key Features & Technical Advantages

• Manufactured according to DIN Z051 standard geometry

• Round taper design for reliable mould alignment

• High positioning accuracy and repeatability

• Effective protection of parting surfaces

• Suitable for high-cavity and high-cycle moulds

• Stable performance under clamping force and thermal load

• Customized / OEM / Built-to-Print manufacturing available

Applications & Industry Use

DIN Z051 round taper interlocks are widely used in:

• Multi-cavity plastic injection moulds

• Bottle cap and closure moulds

• Packaging moulds with tight alignment requirements

• Medical plastic moulds requiring consistent positioning accuracy

• High-speed injection moulds with frequent opening and closing cycles

They play a critical role in maintaining mould accuracy and long-term service life.

Mould Structure & Design Description

In injection mould assemblies, round taper interlocks are typically installed:

• Between core and cavity plates as precision locating units

• Near mould corners to resist lateral displacement

• In mould structures where parting line protection is critical

• As replaceable wear components for alignment control

All interlocks are manufactured based on standard specifications or customer drawings, including taper angle, diameter, length, and mounting interface.
