General specification for plastic mold cooling system. Generally speaking, we should pay attention to the following points.

1. Cooling nozzles are all made of copper quick-connect nozzles. The standard of use is coiled JJPS2 quick-connect. If the contract has special requirements, the contract stipulates.

2. the cooling nozzle can not extend the surface of the template in principle, and the surface of the head of the nozzle can not be larger than 3mm. Diameter of the hole.

For more than 25mm, the outer edge of the hole should be chamfered with chamfering greater than 1.5 * 45 degrees.

3. Cooling water must be fully designed and unblocked to meet the requirements of product production; in principle, the temperature difference between cavity and core should not exceed + 5.

4., reliable sealing, no leakage, easy to overhaul, nozzle installation should be wrapped raw material belt. Sealing grooves for sealing rings shall be machined according to relevant standards in size and shape. Sealing grooves shall be arranged on the template and shall not be machined on the inserts.

5. watertight panels should be made of non corroded materials, usually brass or stainless steel.

6. The cooling nozzles of the inner and outer sliders must be conveniently connected with the quick connection nozzles, and shall not affect the normal operation of the die.

7. mold cooling system water test: the inlet pressure is 0.5Mpa, and the water is maintained for 5 minutes.
