Background technology

With industrial and commercial industry fast development today, it applies in the various plastic forming products, mould is the important person who has rendered outstanding service for the exploitation of various product external form, in process, in the cooling procedure behind the gate solidification, the die cavity internal pressure can't be controlled, therefore the specific volume that influences in the die cavity changes, then depend on temperature in the die cavity, causing the type of cooling is the onlooker outside structure, precision, the intensity of this finished product reach that concerns, if can obtain best cooldown rate, just can make the cost quality-improving, so cooling system is an important ring in the molding process.

So in this tradition cooling form of construction work, can divide into kinds such as following, and after cooperating graphic being described in more detail in, to increase the understanding to these structures.

Early stage mould 100 is in the cooling form of construction work (as shown in Figure 1), be in these mould plastic 120 finished product pan feeding places, suitably be drilled with a through hole 130 in the distance, and attack system with internal screw thread in the both sides orifice end, with constructing with the cooling of carrying out its cooling water for screwing togather both sides water bolt 110, so wait in the mould because of with being drilled with its through hole in relatively large, instead this construction method increases its operating personnel's inconvenience, and is difficult to overcome because of cooling off puzzlement such as not enough generation dead angle.
