How to debug the moulds after installation?
Forming dies in the move, after the template is installed on a fixed, to the examination of the idle running test debugging, to ensure that, on the template of the two halves of the forming die, clamping movement coordinated with clamping mechanism of action, for the injection molding production work smoothly and avoid malfunction or damage to the mold work.
The sequence of mold adjustment test is as follows.
Check whether the sliding fit of the guide column and guide sleeve on the mold can be properly guided in the opening and closing of the mold, and the sliding coordination of the two parts should be free of clamping interference phenomenon.
Low pressure, slow closing mode.Check whether the working process of the two and half modes is accurate, and the two parts should be closely connected.
If the combination of the two halves of the mold is normal, then tighten the clamping nut once again.Note that the tightening force of each nut should be uniform.
A slow opening mode.Adjust the working position of ejection rod, the ejector rod working position adjustment to make the mold ejection plate with fixed template between periods of not less than 5 mm, the ejection rod can work properly, and can prevent the damage to the mold.
(5) on the top output or open mold force to realize core-pulling motions of mould, should pay attention to action of ejection rod should coordinate and the core pulling distance and to ensure the safety and accuracy of the two institutions, and mutual interference phenomenon, prevent work or damage to the mold will not work.
To adjust the distance dimension of the moving template to adjust the control switch of the fixed stroke.
Adjust and test clamping force.The debugging of the clamping force should start from the low value, and the stretching movement of the elbow connecting rod should be more flexible and easy.If there is a certain temperature in the molding process according to the process conditions of injection products, the debugging work of the clamping force should be carried out after the specific temperature of the mold has been raised to the process temperature.
After all the parts of the mould and die fitting are adjusted, the sliding fit parts should be properly filled with lubricating oil.
It is equipped with auxiliary accessories such as electric heating element, control instrument, hydraulic, pneumatic and cooling circulating water pipeline installation.Then the debugging is conducted to check the accuracy of resistance heating and instrumentation control.Reliability of hydraulic and pneumatic pressure testing and testing;Check whether there is leakage in all pipe connections.
The commissioning of the mould, the adjustment of the mould and die force are completed and the commissioning test is started.The injection molded plastic product is reasonable without the minimum locking force of the flying edge.The large clamping force can easily deform the mould, and it will accelerate the wear of each part in the mould.More suitable mould force (clamping force) can also save energy consumption.
