Die casting mould installation is a complex and highly technical job, which needs to be operated in strict accordance with specifications.

To ensure the normal operation of the mold and the quality of the product.

Preparation before the installation of the die casting mould

Die casting mould inspection

First of all, check whether the mold is intact, whether the parts are complete, and whether the surface is clean and dust-free.

Secondly, confirm that the mold matches the model of the die-casting machine to avoid installation failure caused by the mismatch of mold size or structure.

Finally, check the accuracy of the mold, including whether the dimensions of key components.

Such as cavities, cores, guide pillars, and guide bushings meet the requirements.

Equipment inspection

Before installing the mold, it is necessary to check whether the lifting equipment, hook bolts, and screw holes of the die-casting machine are in good condition to ensure that the equipment can safely carry the mold.

It is also necessary to confirm that the hydraulic system, cooling water channel and lubrication system of the die casting machine are working properly.

Site Preparation

Clean the mounting surface of the die casting machine to ensure that it is flat and free of debris.

Also, prepare the necessary tools and auxiliary equipment, such as screws, gaskets, lubricants, etc.

Mould installation steps

Hoisting the mould Use lifting equipment to lift the mold onto the die-casting machine, taking care to avoid damage to the mold.

Place the mold on the moving mold holder and make sure that the centerline of the mold is aligned with the injection chamber flange table.

Fixing the mold

Fix the top of the mold on the guide rail, and increase the fixing strength through screws.

Ensure that the slider stroke of the mold is flexible and the positioning is accurate.

Adjust the clamping clearance

Adjust the clamping clearance of the mold to make it meet the design requirements.

Use the clamping trial method to check whether the mold is completely closed to ensure that there is no gap.

Install the cooling system

Make sure the cooling water is clear, connect the cooling water pipes and check the tightness.

For special molds, such as those with cooling channels, thermally conductive components need to be installed to reduce cooling costs.

Debugging the mould

Start the die-casting machine for no-load debugging and check whether the mold is running smoothly.

Adjust the slider stroke and the length of the push rod to ensure that the mold action is coordinated.

Precautions for mould installation

Regular Inspection and Maintenance

Regularly check the integrity of lifting equipment, bolts and bolts to ensure safety when lifting heavily.

It is best to check the cleanliness and lubrication of the mold, and clean the burrs or impurities on the surface of the mold in time.

Mould preheating and heat preservation

Preheat the mould before production to ensure that the mold temperature meets the process requirements.

If necessary, use a holding furnace or other heating equipment to preheat the mold.

Parameter Adjustment & Optimization

Adjust injection parameters, cooling time, and lubrication frequency according to production needs.

For molds with complex structures (e.g. molds with sliders or core-pulling mechanisms), special attention should be paid to the coordination of their movements.

Operational Training & Safety Specifications

Die casting operators need to be professionally trained and familiar with operating procedures.

The most important thing is to follow safe operating procedures to avoid mold damage or personal injury due to improper handling.

Common problems and solutions for mold installation

Loose clamping

Check whether the clamping gap is too large, and readjust the clamping parameters if necessary.

Cooling system leakage

Check the cooling water pipe connection for leakage and replace the damaged parts in time.

Abnormal slider action

Check whether the slider stroke is flexible, adjust the slider positioning or replace the damaged parts if necessary.

Mold surface scratches

Use gasket protection during mold handling to avoid scratches caused by direct contact.

Haichen Experience

The installation of die-casting mold is a systematic project, which needs to be strictly controlled from mold inspection, equipment preparation to installation and commissioning.

Through scientific and standardized operation and timely maintenance.

It can effectively improve production efficiency, prolong the life of molds, and ensure product quality.

At the same time, die casting engineers need to continuously optimize the process parameters according to production needs to improve the overall production level.
