Injection molds are components that give plastic its shape and size during the molding process. They are manufactured by injection molding plastic raw materials at high temperatures. Common cosmetic packaging is also produced through injection molding, resulting in a variety of cosmetic packaging materials, such as lipstick tubes, lip gloss tubes, eyeshadow compacts, powder compacts, and mascara tubes. In addition to cosmetic packaging, there are also injection-molded parts for everyday use, such as
Plastic Home Appliances. Next, the editors of HUIWEN Plastics will briefly discuss the introduction to and components of injection molds produced by plastic products factories.
Injection mold design considerations for injection molds produced by plastic products factories:
1. Determine the parting surface and gate location based on the performance and molding properties of the plastic part.
2. Consider the processability of the mold manufacturing process and determine the design based on equipment availability and technical capabilities. Ensure that the mold, from the entire mold to the individual components, is easy to process and maintain dimensional accuracy.
3. Consider injection productivity, increase the number of injections per unit time, and shorten the molding cycle. 4. Dimensions requiring precision, as well as structures such as holes, columns, protrusions, and recesses, must be reflected in the mold. This means that no or minimal processing is required after the mold is formed.
5. The mold structure should be simple, adaptable, stable, reliable, and require fast cycle times and low costs, facilitating assembly, maintenance, and replacement of consumable parts.
6. Mold material selection and processing.
7. Standardized mold production: Utilize standard mold bases, commonly used ejector pins, guide components, sprue bushings, retaining rings, and other standard components whenever possible.
Basic Components of an Injection Mold
1. Gating System: The channel through which molten material flows from the injection molding machine nozzle into the mold cavity. This includes the main runner, branch runners, gates, cold wells, and pull rods.
2. Molded Parts: The parts that mold the part, such as the core, cavity, and other auxiliary components.
3. Temperature Control System: Used to regulate the mold temperature.
4. Ejection System: This includes the side parting mechanism, secondary ejection mechanism, pre-reset mechanism, and sequential distance parting mechanism.
5. Mounting System: The part that securely mounts the mold body to the injection molding machine. 6. Connection System: This system connects the various structural components together.
7. Guide System: This system ensures the precise movement of the various structural components relative to each other, such as guide posts and guide rails.
