In addition, the concave and convex matching design of the upper and lower mold cores ensures the molding accuracy and extends the service life of the mold. Optimize the cooling system: the first and second water transport structures integrated inside the mold can efficiently and evenly cool the mold, reduce the molding cycle, improve product quality, avoid product deformation or defects caused by local overheating, and ensure the consistency and surface finish of the product. Enhance demoulding performance and reduce wear: the first wear-resistant block slot set around the lower mold frame significantly reduces the wear of the mold during long-term use by installing wear-resistant materials, thereby improving the durability of the mold.

This design not only simplifies the complexity of the cooling system, but also significantly improves the heat exchange efficiency, avoids the problem of plastic part deformation caused by local overheating, and extends the service life of the mold.

[0010] In some embodiments of the utility model, the material port is connected to a "V"-shaped material channel. Material flow optimization: The "V"-shaped material channel design connected to the material port uses its natural guiding characteristics to effectively guide and accelerate the flow of plastic melt, reduce injection pressure loss and shear heat generation, ensure that the material evenly fills the mold cavity, improves the consistency and surface finish of the molded part, and also reduces energy consumption during the injection molding process.

[0011] In some embodiments of the utility model, a third wear-resistant block slot is further provided in the lower die core-pulling slot.

[0012] Enhanced durability: A third wear-resistant block slot is added to the core-pulling slot of the upper die. By installing the wear-resistant block, the wear resistance of the die during frequent extraction is greatly enhanced. This design detail effectively extends the life of key components of the die, reduces maintenance costs and downtime, and ensures long-term stable production efficiency and product quality.

In addition, this design also facilitates the replacement and maintenance of the ejector, further improving the overall operability and maintenance convenience. BRIEF DESCRIPTION OF THE DRAWINGS
