Basic knowledge of Injection mold construction structure includes the following points:

1. Mold structure: Injection mold construction is generally composed of upper mold, lower mold, approach plate, guide pillar, guide sleeve, ejector pin, bottom needle, nozzle and other parts. Different products require different mold structures, so designing and manufacturing molds requires structural design based on product requirements.

2. Injection mold construction materials: commonly used Injection mold construction materials include P20, 718, NAK80, S136, etc. These materials have high hardness, wear resistance, and corrosion resistance, which can meet the injection molding needs of most products.

3. Design points: the design points of Injection mold construction include product design, mold design, process design, etc. Among them, process design is very important because it directly affects the quality and efficiency of product processing.

4. Maintenance: If the Injection mold construction is not well maintained during use, it may be damaged or have other faults. Therefore, Injection mold construction needs regular maintenance, including cleaning, lubrication, inspection and other operations.

5. Mold life: The life of Injection mold construction depends on many factors, including mold material, design, use frequency, maintenance, etc. In order to extend the life of Injection mold construction, it is necessary to design and maintain the mold reasonably.
