Today, I will introduce you to the following aspects when choosing an injection molding machine in the production of plastic molds.

What needs to be paid attention to when choosing an injection molding machine mold?
1. The length and width of the mold should be smaller than the distance between the pillars to ensure that the mold can be placed in the injection molding machine for production;
2. The thickness of the mold should be within the range of the minimum and maximum mold thickness of the injection molding machine;
3. Check the mold opening stroke of the injection molding machine to ensure that there is enough space to take out the product smoothly under the maximum mold opening stroke;
4. Inspect the injection weight of the injection molding machine, which is more than 2 times the weight of the molded product (including the runner part);
The ball diameter of the gate sleeve and the diameter of the glue inlet selected on the mold are larger than those of the nozzle of the selected injection molding machine to ensure that the molten plastic can smoothly enter the mold cavity without leakage;

6. Select the diameter of the positioning ring of the mold according to the diameter of the positioning ring hole on the selected injection molding machine to ensure that the two match;
7. Ensure that the ejection stroke of the injection molding machine is greater than the actual stroke required to eject the product;
8. The hidden depth of the positioning ring nozzle on the mold should be less than the maximum extension of the injection molding machine nozzle;
9. Molds designed to be produced on injection molding machines greater than 500 tons (including 500 tons) must have a movable mold positioning ring.
10. In order to reduce the difficulty and accuracy requirements of the mold hoisting, the diameter of the ejector pin hole on the movable mold bottom plate of the mold is larger than that of the ejector pin hole on the injection molding machine.
