A turn the control panel switch to manual
B close the ball valve in front of the clamping cylinder
C. start the mold closing switch. After the core rod returns to its position, turn the mold closing switch to the middle position
2. Shooting plate installation:
Connect the nozzle with six m8x30 hexagon socket screws and connect the cooling water pipe
3. Die adjustment
1) Center adjustment:
Move the ejector head to the working position, adjust the mobile hand wheel of the movable frame and the adjusting screw of the workbench to make the mold center and the ejector head center most accurate
2) Closing gap adjustment:
Adjust the positioning screw of the fixed die to make the left and right half die close and clean the seam
4. Installation and adjustment of core pulling block:
1) Move the movable block to a proper position and fasten it
2) Adjust the movable block to move the upper and lower dead points and fasten them
2) The up and down stroke is adjusted by the limit rod
Carry out the following maintenance regularly
1. Pay attention to keep a certain amount of oil in the atomizer;
2. At the end of each work shift, the sand shooting head must be removed to clean up the accumulated sand, and the sand in the exhaust plug must be blown off;
3. At the end of each work shift, the accumulated sand on the worktable and column must be completely removed;
4. At the end of each work shift, the remaining sand in the sand bucket must be removed and the inner wall of the sand bucket must be wiped clean, so as not to affect the work due to hard sand accumulation;
5. At the end of each work shift, the condensed water in the machine and main pipe must be drained;
6. All electrical circuits and contacts must be checked frequently, otherwise the cable insulation is damaged and the terminal block of the box is loose, which will cause great loss;
7. Repair the machine once a month and check the sealing surface;
8. Clean the sand in the muffler frequently to ensure its smoothness;
