Composition of the quick mold change system: clamp, mould transfer arm, mould lifter, pneumatic and hydraulic power unit, control system and so on.

The Quick Mold Change System is a mold replacement solution for molding equipment. Such as injection molding machines, stamping machines, and die casting machines. Its main purpose is to shorten mold replacement time, improve production efficiency, reduce costs, and improve product quality.

The quick mold change system composition consists of a clamp, a mold transfer arm, a mold lifter, a gas-liquid power unit, a control system and a mold change cart, etc.

It uses hydraulic or pneumatic power to achieve quick mold change. Its main advantages are shortening mold change time, improving production efficiency and reducing costs. It is suitable for a variety of molding equipment and industry scenarios.

Main components

A complete quick mold change system has four core units. They work together for fast mold change and reliable clamping.

Clamping Units

• Clamping units directly hold the mold, including clamps and cylinders
• Clamps mount in T-slots or special mounting holes on the platen
• Hydraulic clamps provide high force, suitable for large machines
• Pneumatic clamps have simple structure, for small to medium machines

Positioning Units

• Positioning units ensure exact mold location on the platen
• Includes locating rings, keys, guide pins
• Positioning accuracy directly affects casting consistency
• Repeat accuracy up to ±0.05mm

Power Units

• Power units supply hydraulic oil or compressed air to clamps
• Hydraulic power unit includes pump, tank, valve block, pressure switch
• Pneumatic power unit includes air preparation unit and solenoid valve
• Must have pressure monitoring and loss protection

Control Units

• Control units coordinate clamping, release, and safety interlock
• Includes PLC, control panel, pressure sensors, limit switches
• Integrates with main machine control for interlock
• Supports manual and automatic operation modes

Quick mold change system working principle

The quick mold change system completes the steps of unlocking, separating, installing and positioning the mold through automated operations. The specific process includes:

• Positioning and clamping
• Unlocking and separating
• Installation and positioning of the new mold
• Clamping and locking

Positioning and clamping

Fix the old mold on the equipment to ensure its stability.

Unlocking and separating

Separate the mold from the equipment through the unlocking mechanism.

Installation and positioning of the new mold

Install the new mold in place and position it.

Clamping and locking

Use the clamp to fix the new mold on the equipment.

Advantage of the quick mold change system

• Improved production efficiency
• Enhanced production flexibility
• Reduced labor costs
• Stable quality

Improved production efficiency

Mold change time is reduced by 30-60%, significantly reducing machine downtime.

Enhanced production flexibility

The same machine can complete small batch production of multiple varieties within the same day.

Reduced labor costs

Standardized mold change procedures enable minimal or no human operation.

Quick mold change system composition: Stable quality

Fast and precise positioning reduces human error and lowers defective product rates.

Future trend

• Rising demand for flexible manufacturing
• Integration of digitalization and intelligence
• Standardization of modular molds

Rising demand for flexible manufacturing

Industries like automotive and consumer electronics require small batches and a wide variety of products, making rapid mold change a key technology for achieving flexible production.

• For example, Haichen adopts aluminum die casting machine techniques to proudce high-quality aluminium alloy cookware pans. Under high-pressure die casting (HPDC) cold chamber die casting machine.with exceptional efficiency and performance.

• By injecting molten aluminum into precision steel molds under intense pressure, this process enables the rapid production of pots with complex, thin-walled geometries and excellent dimensional consistency. The result is lightweight yet durable cookware with superior heat distribution.
• Key advantages include high production speeds, minimal material waste, and the ability to integrate reinforced structures and intricate surface details directly into the casting, ensuring both functional excellence and aesthetic appeal in every piece.
• Haichen can also produce replaceable pot bottom moulds for same diameter with different bottom shape pans. That can help save and reduce customer’s significant cost.

Integration of digitalization and intelligence

Industrial Internet platforms enable predictive maintenance and automated scheduling of mold change processes, further shortening mold change windows.

Standardization of modular molds

Suppliers are introducing standardized mold interfaces (such as the Quick-Mold series from Germany and the United States), reducing companies’ in-house R&D costs.

Practice of quick mold change on die casting machines

HAICHEN provides integrated quick mold change systems for die casting machines. They help customers cut change time and increase efficiency.

Troubles of customer change mold

• A die casting plant made many aluminum parts, changed molds 3-5 times daily
• Manual change took 2-3 hours each, long downtime
• Needed multiple test shots after change, affected efficiency
• Customer wanted change time under 30 minutes

HAICHEN Quick Mold Change Solution

• Hydraulic clamping unit with 8 clamps evenly spaced
• Locating rings and keys for repeat accuracy ±0.05mm
• Hydraulic power unit integrated into machine hydraulic station
• Control unit linked with machine PLC for safety interlock

After solution result

• Mold change time from 2.5 hours to 20 minutes, down 85%
• No repeated adjustment after change, mold in place first time
• OEE up 15%, about 500 more production hours yearly
• Less operator labor, better safety

Advantages of HAICHEN Quick Mold Change

• Integrated with machine, no separate hydraulic unit needed
• Control logic in main PLC, easy to operate
• Standard mold interface, customer’s new molds work directly
• Fast after-sales support for long-term reliability
