1. Preparation before installation
Please verify the functionality of the cooling water circuit and ensure that the screw is inserted into the machine board at a depth of 1.5-1.8 times the diameter of the screw. Inadequate screw insertion can lead to teeth slippage and pose a risk of mold falling. It is crucial to confirm the availability of the necessary personnel, materials, tools, documents, equipment, and auxiliary machinery for a smooth production process.
2. Method of hanging formwork
If the hanging mold is not level, it can lead to various issues in the front and rear model cavities of the installed mold. These issues include poor concentricity, segment differences, inaccuracy in tooth shape, and irregular distances. It is crucial to address the alignment of the mold to ensure optimal precision and quality in the produced items.
When installing the mold, it is crucial to address the following concern. Ensure that when the suspended mold is in place, it can be manually pushed to a smaller position before closing. Adjust the lifting ring based on the front mold, as it is secured with a positioning ring. Align the rear mold with the front mold for optimal level and matching of the mold cavity position. Proceed to close the mold until it is fully sealed, but refrain from applying high pressure initially. It is advisable to avoid using high voltage until it is confirmed that the mold can be properly closed.

3. Method of screwing
When dealing with molds below 50 degrees Celsius, it is crucial to follow the correct tightening sequence. Begin by closing the mold and applying high pressure before tightening the screws diagonally on the front and rear molds. Once 8 screws have been tightened, avoid overtightening until the mold temperature reaches 50 degrees Celsius. Then, begin the molding process under high pressure and continue tightening the screws diagonally to ensure optimal mold performance. Remember to always adhere to the recommended guidelines for safe and efficient molding operations.
As the temperature rises, the mold material experiences an expansion in volume, causing it to swell. This swelling effect becomes especially noticeable when the mold temperature is high. It is important to note that if the screws are tightened before the heating process, it can have consequences for both the mold's longevity and its accuracy.
4. Use of accessories
To ensure optimal functionality, the addition of a template becomes necessary when the mold thickness falls short. In cases of elevated mold temperatures, it is advisable to incorporate an insulation board between the machine board and the mold. Regardless of whether a template or insulation board is used, it is crucial to ensure minimal flatness for improved performance.
If the flatness of a mold is too large, this can cause issues with the parallelism of the front and rear molds. Even after high-pressure closure, there may still be a noticeable difference, which ultimately affects the quality of the end product. To remedy this, it's important to ensure that the mold temperature reaches the appropriate set value prior to making any necessary adjustments to the mold thickness. By taking these steps, it is possible to achieve optimal results and ensure that the products meet all necessary quality standards.
