The structure of the injection mold usually includes the following several parts:
1. The forming part: This is the core part of the mold, usually composed of the cavity and the core, which is used to form the shape of the plastic part.
2. Casting system: The channel for introducing the molten plastic into the cavity, including the main runner, the diverging runner, the gate, etc.
3. Guiding mechanism: Ensure that the moving mold and fixed mold of the mold can be precisely aligned during the opening and closing mold process, usually consisting of guide posts and guide sleeves.
4. Demolding mechanism: The mechanism for pushing the plastic part out of the mold, including push rods, push plates, reset rods, etc.
5. Lateral type dividing and core pulling mechanism: For plastic parts with side holes or side recesses, it is necessary to achieve demolding through the lateral type dividing and core pulling mechanism.
6. Temperature regulation system: Control the temperature of the mold to ensure the quality and production efficiency of the plastic parts, usually including cooling water channels and heating elements.
7. Exhaust system: Discharge the air in the cavity to avoid defects such as bubbles and depressions in the plastic parts.
8. Supporting components and parts: Such as fixed plates, supporting plates, and spacers, which are used to support and fix the various parts of the mold.
Of course, the specific mold structure will vary according to factors such as the shape, size, accuracy requirements, and production process of the plastic part. When designing the injection mold, it is necessary to comprehensively consider each factor to ensure that the structure of the mold is reasonable, reliable, and can meet the production requirements.
