金型製造は複雑なプロセスです. 設計のステップから, 処理, 組み立て, デバッグ, NS。, 最終用途へ, 主にあります 10 生涯を通じて金型の品質に影響を与える要因.
1.鋼は金型の品質の決定的な要因です, 適切な鋼材を選択することが最優先事項です.
鋼材を選ぶ基準は:
①NSequirements for injection molding materials
異なるプラスチックは異なる鋼を使用する必要があります, 高研磨の要求など, 耐食性, などz
②Price
If the steel is good, then it is enough, not as expensive as possible; considering the cost of the mold, the mold steel should use the material corresponding to the life of the mold to avoid unnecessary waste; the life of the general P20 material is about 300,000; 2738 materials are no problem at 500,000, H13/2344 is usually more than 80-100 million, and can be selected according to the situation;
③Surface finish
The surface treatment of the mold is also very important. Nitriding can enhance the surface hardness of steel and effectively extend the life of the mold. Electroplating can effectively modify the mold steel. For some high-brightness and corrosion-resistant plastic parts, electroplating can be used to enhance and improve the performance of the steel.
- Structural design
The completed mold structure not only considers the product material properties, shrinkage rate, molding temperature, elastic tensile deformation coefficient, NS。, but also considers the cooling water passage, the speed of opening and closing the mold, and the like. Reasonable mold structure can effectively extend the life of the mold and ensure the smooth production of the mold, improve efficiency and reduce costs.
- Mold processing
If a worker wants to do something good, he must first sharpen his tools. The arrangement of the mold process is particularly important, and the reasonable process arrangement can speed up the production cycle, shorten the processing time, and effectively save costs. And more importantly, accurate and reasonable processing can ensure the stability and longevity of the mold during the production process. Some machining errors will lead to mold welding, no matter how good the welding is, it is a loss to the mold; in addition, poor processing may affect the mold movement, reduce the mold life, and cause the mold to crack during the production process, even broken.
- Stand parts
The lowest bar is the one that determines the capacity of the bucket. Everyone understands this truth, but it is often not noticed when doing it. The mold is the same, although the standard parts are not directly involved in the molding, but control the operation of the entire mold. Good standard parts should be wear-resistant, hard enough, 高精度, and not suitable for deformation. Different brands of standard parts are very expensive, so don’t blindly kill the mold, kill it, and your mold will drop from Mercedes to the public.
- Collision
The experience of the mold fitter is against the seemingly simple work but the most technical work. The main thing about complex molds is this effort. The flat mold is the simplest, and the fractal surface is basically ok as long as there is no flash break. It is very troublesome to use a car accessory mold. Not only is the fractal surface relatively irregular, but it often includes multiple sliders and top blocks. 同時に, it can improve and perfect other problems of the mold through the touch, so it is a comprehensive work.
- Polished/skinned
The polishing of the mold is the last step in the manufacture of the mold. Polishing is directly reflected on the plastic parts, so this is the most face-to-face job. Polishing also helps and complements the mold movement, especially for demolding. Often some mold production is not smooth because the lighting is not in place, the resistance is too large, the demoulding is difficult, and even the white, the top crack and so on.
- Mold assembly
Mold assembly is like assembling a machine. Every component and every screw can’t go wrong. さもないと, the consequences will be quite serious. If it is light, it will lead to product defects, affecting production, and completely damage the mold and cause scrapping. したがって、, the assembly work must be very detailed.
In the assembly process, especially pay attention to the cleaning of the mold, especially the water circuit and screw holes. Be sure to blow off the iron filings inside.
- Hot runner or cold runner
This actually has the least impact on the quality of the mold, because the hot runners are generally branded by customers, especially some large customers. Well-known foreign brands do very well in quality and after-sales service, so there is generally no problem in quality. しかしながら, some domestic hot runners have a very different quality. コストを節約するために, individual small enterprises strive for price advantages, and with some unreliable heating and conduction accessories, problems are easy to occur. The main problem of the cold runner is how to ensure the balance of injection molding, gate size, 射出圧力, NS.
- The cooling water channel
Anyone with experience in mold knows how important cooling is to a mold.
Due to the increase in prices and labor wages, it is unthinkable to reduce the profit from the one-second injection cycle when mass-producing products. しかしながら, when the production cycle is accelerated, the temperature of the mold will rise. If it is not effectively controlled, the mold will be too hot to be formed, and even the mold deformation will be scrapped. したがって、, excellent waterway design is particularly important, including the arrangement density of waterways, diameters, links between each other, 等々.
- 金型のメンテナンス
During the production process, mold maintenance is important. The mold is like a car. If it is not used for a long time without maintenance, it may cause the mold to be scrapped. したがって、, every time the mold is used, it must be fully maintained, especially the rust prevention of the molded part and the rust prevention of the main moving parts. Because the mold has to be watered during the production process, it may fall into the mold during the installation or disassembly process, so be sure to dry the mold and then apply a layer of oil protection.
