Second-hand mold refers to a mold that has been used by other manufacturers and is no longer in use. It is generally cheaper than a new mold, and it can be used for the production of various products. However, the quality of a second-hand mold is not as good as that of a new mold, so it is necessary to maintain and care for the second-hand mold to ensure its quality and service life. This article will introduce how to maintain and care for second-hand molds from the following aspects: cleaning, inspection, rust prevention, and maintenance.
Cleaning is an important part of the maintenance and care of second-hand molds. If the mold is not cleaned in time, the mold will be damaged, and it will affect the quality of the product. The cleaning of the mold can be divided into the following steps:
First, remove the mold from the mold base, and place it on a clean workbench. If the mold is too large, it can be cleaned in place, but it should be cleaned in a designated area to prevent dust and debris from falling into the mold.
Use a brush or a high-pressure air gun to remove the residual material on the surface of the mold, such as plastic, rubber, or other materials. Be careful not to scratch the surface of the mold during the cleaning process.
Use a cleaning agent to clean the mold. The cleaning agent should be selected according to the material of the mold and the material of the product. Generally, the cleaning agent should have the following characteristics: strong cleaning ability, low corrosion, and no residue. After cleaning, rinse the mold with water to remove the cleaning agent.
After cleaning, dry the mold with a high-pressure air gun or a clean cloth. Be careful not to leave any water stains on the mold, as this will cause rust.
After cleaning, check the mold for any damage. The inspection of the mold can be divided into the following steps:
Check the surface of the mold for any damage, such as scratches, dents, or cracks. If there is any damage, repair it in time to avoid affecting the quality of the product.
Check the cooling system of the mold, such as the water channel and the cooling water pipe. If there is any blockage, clean it in time to ensure the normal operation of the cooling system.
Check the ejection system of the mold, such as the ejection pin and the ejection plate. If there is any damage, repair it in time to ensure the normal operation of the ejection system.
Check the guide system of the mold, such as the guide pin and the guide bushing. If there is any damage, repair it in time to ensure the normal operation of the guide system.
Check the mold release system of the mold, such as the mold release agent and the mold release mechanism. If there is any damage, repair it in time to ensure the normal operation of the mold release system.
Rust is the most common problem in the maintenance and care of second-hand molds. If the mold is not properly maintained, it is easy to rust, which will affect the quality of the product. There are several ways to prevent rust:
After cleaning the mold, apply a rust inhibitor to the surface of the mold to prevent rust. The rust inhibitor should have the following characteristics: strong adhesion, good rust resistance, and no pollution to the environment. The rust inhibitor should be applied evenly on the surface of the mold, and the thickness of the coating should be appropriate.
Place a dehumidifier in the workshop where the mold is stored to reduce the humidity in the air. The dehumidifier should have the following characteristics: strong dehumidification, low noise, and no pollution to the environment. The dehumidifier should be placed in a place where there is no direct sunlight, and the air circulation should be good.
Place a desiccant in the workshop where the mold is stored to absorb the moisture in the air. The desiccant should have the following characteristics: strong moisture absorption, no pollution to the environment, and easy to replace. The desiccant should be placed in a place where there is no direct sunlight, and the air circulation should be good.
Maintenance is an important part of the maintenance and care of second-hand molds. Regular maintenance can extend the service life of the mold and ensure the quality of the product. The maintenance of the mold can be divided into the following steps:
Regularly apply lubricant to the moving parts of the mold, such as the guide pin and the ejection pin. The lubricant should have the following characteristics: good lubrication, low friction, and no pollution to the environment. The lubricant should be applied evenly on the moving parts of the mold, and the thickness of the coating should be appropriate.
Regularly check the fastening parts of the mold, such as the bolts and nuts. If there is any looseness, tighten it in time to avoid affecting the quality of the product. The fastening parts should be checked every time the mold is used, and the tightening torque should be appropriate.
Regularly check the wear parts of the mold, such as the guide pin and the ejection pin. If there is any wear, replace it in time to avoid affecting the quality of the product. The wear parts should be checked every time the mold is used, and the replacement cycle should be appropriate.
