Mold Temperature.

If we talk about mold temperatur it's mean we talk about cooling system in the mold. Cooling chanels should be designed to be optimum accordance to the wall thickness of the product. Thick section need wide chanenels and thin section need small channels. Mold temperatures have influence with the srinkage, the surface, distortion and cooling time. Higher temperatur make higher shrinkage and better shine.

5.7 Ejection System.

Mostly the designer develope mold construction only to create ejection system to make mold could run efficiently and automatically during production.

Many various ejection system to drop out the product like below :

Mold with mechanical double ejection and cam lever.

1.mold open   2.slider open by angular pin   3.machine push the ejector plate by ejector rod and ejector pin 1 moving together to push release the product from thread   4.some distance, the cam lever push the ejector pin 2 and ejector plate moving together to drop the product by stripper ring after the product release from the thread.

Mold with two direction unscrew system by spindle, helical nut and thread bushing.
