Mold cooling system

1、Cooling water pipes independent setup can contorl the valve,You can switch the valve at anytime. 2、Pipes are concentrated on one board and marked. 3、Use distilled water. 4、Water press is 0.6-1.2Mpa. 5、Sub-regional control,up、down、left、right and fixed mold、dynamic mold are six groups. 6、Use PLC and touch screen contorl parameter. 7、Point cooling use high water, press is 1Mpa. 8、Installation of temperature sensor in mould,and concentrat to automatic temperature contorl system.

Die secondary squeeze technology

 

Through the analysis of the three-dimensional model, the part marked by the red arrow may have a large wall thickness due to the setting of the transition link and the process rounding, and the casting hot section is formed to shrink during the die casting process. In the process and mold design process
Consider the use of a partial extrusion device (extrusion principle: in the process of die casting, the extrusion device is started immediately after the end of the rapid injection, and the secondary extrusion is performed locally to increase the internal quality density of the product.)
