If the mold heating tube is used in a high-frequency vibration environment, improper fixing and protective measures can easily cause damage to the heating tube, affecting the normal operation of the mold. Therefore, a series of special measures must be taken.
1、 Fixed measures
Adopting seismic brackets: Traditional fixed brackets are difficult to ensure the stability of heating tubes under high-frequency vibration, while seismic brackets can effectively disperse vibration energy and reduce the impact force on heating tubes through special structural design. For example, using a spring bracket with multi-directional shock absorption function, its spring can buffer vibration in different directions, ensuring the stability of the heating tube position in the vibration environment.
Add fixed points: Reasonably increase the number of fixed points according to the length and shape of the mold heating tube. For longer heating tubes, setting a fixed point at regular intervals can effectively reduce the oscillation amplitude of the heating tube during vibration. At the same time, the positions of fixed points should be evenly distributed to avoid excessive local stress.
2、 Protective measures
Use protective sleeves: Choose protective sleeves with high toughness and wear resistance, such as stainless steel corrugated pipes or high-strength rubber pipes, and insert the heating tube into them. The protective sleeve can not only prevent the heating tube from being impacted and rubbed by external objects, but also cushion vibrations to a certain extent. For example, stainless steel corrugated pipes have good flexibility and corrosion resistance, which can effectively protect heating tubes.
Filling buffer material: Fill buffer material such as silicone, sponge, etc. between the heating tube and the protective sleeve. These buffering materials can further absorb vibration energy and reduce the impact of vibration on the heating tube. At the same time, buffer materials can also serve as insulation and insulation, improving the safety and stability of heating tubes.
Strengthen sealing treatment: High frequency vibration may cause the connection of the heating tube to loosen, thereby affecting the performance of the heating tube. Therefore, to strengthen the sealing treatment of all connections of the heating tube, high-temperature and vibration resistant sealant or gasket can be used to ensure the sealing and stability of the connections.
3、 Regular inspection and maintenance
In high-frequency vibration environments, the fixing and protective components of the mold heating tube are prone to looseness, wear, and other issues. Therefore, it is necessary to regularly inspect and maintain the heating tube, replace damaged components in a timely manner, and ensure the normal operation of the heating tube. For example, check the fastening condition of fixed points, the wear level of protective sleeves, and the sealing performance of sealing points every once in a while, and promptly deal with any problems found.
By implementing the above special fixing and protective measures, the reliability and service life of the mold heating tube can be effectively improved in high-frequency vibration environments, ensuring the normal operation of the mold.
