4 steps about the Automotive mould maintenance
1.Recording
The working state of the mold is usually recorded in detail.

Statistics on the use and care of the mold (lubrication, cleaning, rust prevention) and damage.

Based on this, you can find out which parts and components are damaged and the degree of wear.

To provide information on the discovery and problem-solving,

as well as the molding process parameters of the mold

and the materials used in the product.

In order to shorten the production time of the mold,

improve production efficiency and ensure the positive life of the mold.

2.Testing
The company should test the various properties of the Injection mold under the normal operation of the injection molding machine and the mold,

And measure the size of the final molded part.

This information can be used to determine the current state of the mold

and identify damage to the cavity, core, cooling system, and parting surface.

According to the information provided by the plastic parts

the damage state of the plastic injection mold and the measures for maintenance can be judged.

3.Tracking detection
Focus on the detection of several important parts of the plastic mold:

The function of the ejection and guiding parts is to ensure the opening and closing movement of the mold and the ejection of the plastic parts.

If any part of it gets stuck due to damage, it will lead to the production stoppage.

Therefore, the thimble and guidepost of the mold should be kept regularly (the most suitable lubricant should be selected)

And regularly check the thimble, guide column, etc. for deformation and surface damage

Once found, it should be replaced in time

After completing a production cycle, apply professional anti-rust oil to the working surface, movement and guiding parts of the mold.

In particular, the protection of the elastic strength of the bearing parts with gears and racks and the spring mold should be emphasized.

To ensure that they are always in top working condition.

The cooling channel is easy to deposit scale, rust, sludge, and algae, which makes the cooling channel section smaller and the cooling channel narrows.

Greatly reduce the heat exchange rate between the coolant and the mold, increasing the production cost of the enterprise.

Therefore, the cleaning of the flow channel should be paid attention to.

For hot runner molds, the maintenance of the heating and control system is beneficial to prevent production failures, so it is especially important.

Therefore, after the end of each production cycle, the ohmmeter should be measured with the band heater, rod heater, heating probe and thermocouple on the mold.

If there is damage, it should be replaced in time and compared with the mold resume

make a record, in order to find problems in a timely manner, take countermeasures.

4.Clean up
Pay attention to the surface maintenance of the mold

Which directly affects the surface quality of the product, The focus is on preventing corrosion.

Therefore, it is especially important to choose a suitable, high-quality, professional anti-rust oil.

After the mold has completed the production task

the residual injection molding should be carefully removed according to different injection molding methods.

Use copper rods, copper wire, and professional mold cleaning agent to remove residual injection molding and other deposits in the mold, then air dry.

Disable the cleaning of hard objects such as wire and steel bars to avoid scratching the surface.

If there is rust caused by corrosive injection molding, use a grinder to grind and polish, and spray professional anti-rust oil.

Then store the plastic injection mold in a dry, cool, dust-free place.
