Key points for the upper and lower molds of injection molds: 1. Preparation work for the upper mold; 2、 Upper mold steps; 3、 Preparation work for the lower mold.

1、 Preparation work for upper mold

1) Firstly, check if the material has been baked. If it has not been baked, the material must be baked first.

2) Check if the machine is empty, the size of the machine is suitable, the ejection is suitable, and the required special functions are available. If any of the requirements are not met, report immediately and wait for notification.

3) Check if the mold is ready, and if not, immediately report and wait for notification.

4) The above three points are all ready, and we will prepare the mold tools, water pipes, and corresponding equipment.

2、 Upper mold steps

1) Pull the mold to the front of the corresponding machine, place it firmly, screw on the corresponding lifting ring, and confirm the ejector pin.

2) Lift the mold smoothly with a crane and slowly place it into the machine, aligning it with the positioning ring of the machine and mold.

3) Slowly close the mold and tighten it tightly.

4) Tie the mold tightly with a pressure plate and slowly loosen the crane and remove it, then remove the palladium again.

5) Apply high pressure and tighten the screws again and align the nozzle.

6) Firstly, check the mold for any abnormalities or necessary equipment before mold opening, and then slowly open the mold after confirmation.

7) After opening the mold, check again if there are any abnormalities in the mold.

8) Find relevant personnel to connect special auxiliary equipment and debug it properly.

9) Install auxiliary equipment such as water, forced pulling, hot runner, etc. as required and test whether these auxiliary equipment are functioning properly.

10) Prepare to power on.

3、 Preparation work for lower mold

1) Stop the injection molding and inject the remaining material from the screw to clean the screw with PP material.

2) Turn off the corresponding water: ordinary water and water from the mold heater.

3) All ready, prepare the mold tools and corresponding equipment: water bucket, air gun, anti rust oil, lifting ring, crane, etc.
