Installation and Adjustment Specifications of Injection Mould

Precheck of injection mould
Before the mould is installed in the injection moulding machine, inspection should be conducted so that quality problems can be found in a timely manner. And then modify the injection mould to avoid removing after installed. When the injection mould fixing plate and the moving platen are separately inspected, attention should be paid to the direction mark so as to avoid wrong when mould clamping.

Oblique guided mould installation
When installing the mould, the two should closely cooperate with safety. If there is a mould for the lateral parting mechanism, the slider should be installed in a horizontal position, that is, the movable block is moved left and right.

Injection mould fastening
After the mould positioning ring is installed in the positioning ring seat of fixing mould plate of injection moulding machine, the mould is closed at an extremely slow speed, so that the movable platen presses the mould gently, and then the pressed plate is used. The pressed plate must be loaded with a pad and must be installed up and down four. When the pressed plate is used, we must pay attention to adjust the height of the screw to the same with the mould foot, that is, the pressed plate should be flat. If the pressed plate is inclined, the die foot can't be pressed tightly. The side of the pressed plate won't be close to the mould to avoid damage to the mould by friction.

Correct the eject distance of eject-rod
After the injection mould is fastened, slowly start the mould until the movable platen stops receding, at this time, the position of eject-rod should be adjusted to the position of between the ejector plate and the movable mould platen on the mould, and there is a gap that not less than 5mm, which is to prevent damage to the injection mould, and can ejecting theinjection moulded part.

Ajustment of closed-mould tightness
In order to prevent overflow, but also ensure that the cavity is properly vented, when adjusting the clamping mechanism of hydraulic injection, mainly based on visual observation and experience, that is, when closing the mould, the elbow firstly fast and then slow, that is not very natural and also it is not too reluctant to straighten out, and the closeness of the mould is just right. For the moulds with mould temperature requirements, mould tightness should be corrected after the mould temperature is improved.

Access to cooling water
After connecting the cooling water, check whether it is unblocked or leaking.
