Mold trial contents (1)--verify the mold actions without resin shot

In the plastic mold trial, we need verify the open ,close, eject action without resin material shots. What actions we need to do and pay attention to? If you are interesting in this topic, we can discuss together. Would you like to comment on it or send messages to me?

• Check the status of mold open / close actions in the low pressure

1. Open / Close the mold with low, middle, high speed, 3 times for each of them. Pay attention to whether the abnormal sound and phenomenon of the blocking in this process.

2. observe there are any interference in the actions mold open / close?

• Check the ejection system in the low pressure

1. Eject with low, middle, high speed, and check if there are abnormal phenomenon.

2. Are there get loose or stuck when ejectors or sleeves are ejected out of the parting line surfaces

3. Are there any locate pin for the eject pins and sleeves?

4. Are there any vibration and unusual sound in the processing?

• Mold components return back in the actions

1. Mold return back with low, middle, high speed 3 times for each of them, to observe if they return back normally.

2. After the ejectors return back, the ejector top surfaces should be higher the part line surfaces less than 0.1 mm

3. Check the stop blocks if it works

4. Are there any interference between the ejectors and sliders

5. Are there any ejectors return back system by force?

• Check the sliders actions in the process

1. Open / Close mold 3 times, and observe the mold if it is smoothly.

2. Is slider normal when it return back, and are there any interference with ejectors

3. Is the sliders locate solid?

4. The sequence of the hydraulic releasing system and other mold components

5. Are there scratched and stuck phenomenons for the sliders
