Problems solved by Plastic Injection Mold
1. The structure of the injection mold should be selected reasonably. According to the drawings and technical requirements of plastic parts, research and select appropriate molding methods and equipment, combined with the machining capabilities of the factory, propose the injection mold structure plan, fully solicit opinions from relevant parties, conduct analysis and discussion, so as to design the injection mold structure Reasonable, reliable in quality and easy to operate. When necessary, according to the needs of injection mold design and processing, the requirements for modifying the drawings of the plastic parts can be proposed, but it can be implemented after obtaining the user's consent.
2. The size of Plastic Injection Mold parts should be calculated correctly. Molded parts are the direct factors that determine the shape, size and surface quality of plastic parts, which are closely related and require special attention. When calculating the size of molded parts, generally the average shrinkage method can be used. For plastic parts with high precision and need to control the mold repair margin, it can be calculated according to the tolerance zone method. For large precision plastic parts, try to use the analogy method to calculate the shrinkage rate of the measured plastic part geometry in different directions. Make up for the influence of certain factors that are difficult to consider in theory.
3. The designed injection mold should be easy to manufacture. When designing an injection mold, try to make the designed injection mold easy to manufacture and cheap. Especially for those more complex molded parts, it must be considered whether to use general mechanical processing methods or special processing methods. If a special processing method is used, how to assemble after processing, similar problems need to be considered and solved when designing the injection mold, and at the same time, the mold repair after the trial mold should be considered, and sufficient mold repair margin should be left.
4. The designed injection mold should be efficient, safe and reliable. This requirement involves many aspects of injection mold design, such as the gating system needs to be filled, the module is closed, the temperature adjustment Xirong effect is good, and the demoulding mechanism is flexible and reliable.
5. The injection mold parts should be wear-resistant and durable. The durability of Plastic Injection Mold parts affects the service life of the entire injection mold. Therefore, when designing such parts, not only should the material, processing method, heat treatment, etc. be required, the pin parts such as push rods are also easy to get stuck. Bending, breaking, and the resulting failures account for most of the injection mold failures. For this reason, how to adjust and replace conveniently should also be considered, but it should be noted that the life of the parts is compatible with the injection mold.
6. The structure of the injection mold should adapt to the molding characteristics of the plastic. When designing an injection mold, you should fully understand the molding characteristics of the plastic used and try to meet the requirements, which is also an important measure to obtain high-quality plastic parts.
