2. Different characteristics: the general structure of the die core is extremely complicated, and the processing is very difficult and the cost is high. The firing pin ejection is a structural form of ejection system. The first time the needle was pinned between the needles, the second time it was just inserted.
3, different functions: plastic mold thimble can also be used in the mold, which can play a stable role. The thimble is also the most commonly used tool to separate the product from the plastic mold. The mold core is suitable for plastic molds that require high hardness, high toughness and wear resistance. After nitriding, the life of the die can be prolonged.
Extended data:
Precautions:
1. Whether the shape of the plastic product is reasonable, whether it can be ejected smoothly, and whether the surface quality of the product will be affected during ejection. Whether the cavity and core of plastic mold are easy to process and whether there is a better design scheme for its processing.
2. Because the plastic mold adopts the insert structure, the surface of plastic products often has the problem of insert line clamping, so it is necessary to confirm with the customer whether the customer agrees with this line clamping method.
3. Is it difficult to process plastic molds, such as wire cutting, electric spark and numerical control?
4. Whether the reinforcing rib of plastic mold is easy to mold, if it is not easy to mold, we should consider the mosaic structure.
