Matters needing attention in upper and lower dies of injection mold

1. Measure the length, width and height of the mold, and judge whether the mold can be installed on the selected machine according to the measured data.

2 Measure the outer diameter of the mold locating ring to see if it matches the mounting hole on the fixed template of the selected machine.

3. Measure the gate size of the mold and the distance between the gate and the installation plane of the fixed template mold of this machine, and judge whether the nozzle of the selected machine injection seat can match the mold well.

4. Measure the size of the ejector plate of the mold and compare it with the ejector stroke of the selected machine to determine whether the machine is suitable.

5. According to the actual thickness of the mold, roughly adjust the thickness of the mold by manually adjusting the mold, and then set the mold opening distance according to the space distance required for the product to be demoulded and dropped smoothly after mold opening. Manually adjust the mold to make the mold opening distance reach the set value. Loosen the nut of the mechanical safety bar on the movable formwork, and turn it back by one nut and screw it in by another nut to make the safety bar move left and right. When it is adjusted to the mold opening position, the protective door is opened, and the mechanical safety baffle installed at the top of the fixed template will automatically fall off, and the protrusion at the right end of the safety rod is just close to the safety baffle. Then lock the bumper nut.

6. Set the ejection stroke according to the design parameters of the die. So as not to damage the mold when adjusting the thickness of the mold.

7. Prepare the die platen, platen pad, compression bolt, nut, flat washer, spring washer, wrench, pipe fittings, etc.
