Precautions for die casting mold installation

(1) The mold installation position meets the design requirements, and the distance between the mold expansion force center and the die-casting machine is minimized as much as possible, so that the force of the die-casting machine's big bar may be more uniform.
(2) Frequently check whether the mould lifting eye bolts, quality die casting,screw holes and lifting equipment are in good condition to ensure the safety of persons, equipment and moulds during heavy lifting.
(3) Regularly check the force error of the big bar of the die-casting machine, and adjust if necessary.
(4) Wipe the machine mounting surface and mold mounting surface thoroughly before installing the mold. Check whether the length of the ejector rods used is appropriate, whether the lengths of all ejector rods are the same length, the number of ejector rods used should not be less than four, and they should be placed in the specified ejector rod holes.
(5) The pressure plate and pressure plate bolts should have sufficient strength and precision to avoid loosening during use. The number of pressing plates should be enough, preferably on all sides, with no less than two places on each side.
(6) Large molds should have mold brackets to prevent the mold from sinking, dislocating or falling during use.
(7) Moulds with larger core pulls or moulds that need to be reset may also need to be installed separately from the movable and fixed molds.
(8) The cooling water pipe and installation should be sealed.
(9) Adjustment after mold installation. Adjust the clamping tightness. Adjust injection parameters: fast injection speed, injection pressure, boost pressure, slow injection stroke, fast injection stroke, punch follow-up distance, push-out stroke, push-out reset time, etc. After the adjustment, put soft objects such as cotton silk in the pressure chamber, do two simulations of the entire injection process, and check whether the adjustment is appropriate.
(10) Adjust the mold clamping to a proper distance between the moving and fixed molds, stop the machine, and put it in the mold preheater.
(11) Set the holding furnace at the specified temperature, and configure a scoop of specified capacity.
(12) Confirm the integrity of the mold before production, correctly connect the neutron tubing and control switch circuit to the mold with neutron, confirm that the metal of the conductive part is not exposed, and select the control program before operation.
(13) The mold with inverted pull device must be equipped with an inverted pull rod, and the thimble must be returned after being ejected, otherwise the mold cavity will be damaged.
(14) When opening the mold twice, the front half of the back mold must be opened first when the mold is opened, otherwise the mold core will be damaged.
(15) Moulds with sliders above and on the left and right sides of the mould must be fixed with appropriate springs.
(16) Molds with slider cores, core-pulling structures and complex structures that are easy to jam should be fully preheated before production (the mold cavity must be oiled before preheating).
(17) For molds with orientation requirements for cores or shared cavities, the correctness of the cores must be confirmed.
