Many people know that the method of manufacturing plastic materials into plastic products by using injection molding machines and molds is called injection molding. What are the 7 systems that make custom injection molds?

The custom injection mold consists of seven systems: the guiding system, the support system, the forming part system, the gating system, the cooling system, the ejection system, and the exhaust system.

The mold consisting of the above systems, the plastic through the pouring system, through the gate into the cavity, after the filling pressure is cooled by the cooling system, the product is condensed and solidified, and then ejected through the ejection system to complete a molding cycle.

Gating system: The passage through which the plastic melt flows out of the nozzle of the injection machine before reaching the cavity.
The mold cooling system includes: a cooling water channel, a mold temperature controller, and a heating assembly.
 

Eject system:

The ejector of the product is the last step in the injection molding process. When the product is cured in the mold, an effective way is needed to eject it from the mold. The quality of the topping will ultimately determine the quality of the product. Therefore, the ejection of the product cannot be ignored. Moreover, in the ejection, the product cannot be deformed, whitened, broken or the like to damage the product. This device is the ejection system. The ejector system has the following categories: 1. Dome needle 2. Flat thimble 3. Sleeve 4. Ejection block 5. Stripping plate 6. Oblique pin 7. Gas cap.

Exhaust system:

Exhaust purpose: to reduce the wind, scorch and other defects caused by the presence of gas in the mold.

Guidance system:

In the mold, the guiding mechanism is mainly used to ensure the exact matching between the male mold and the female mold or other parts in the mold to ensure the shape and dimensional accuracy of the plastic products, and to avoid various parts in the mold. Collision and interference occur.

Support system:

Function: The injection molding machine has a large injection pressure. When the span between the two mold feet is large and the strength of the male template is not enough, the male template will produce twist deformation. The use of the support column (SP) is formed at the bottom of the male template. The fulcrum minimizes the deformation of the male formwork.
