Factors that should be considered in the design of precision molds
Release: admin Browse: 416 times
With the development of the industry, people have higher and higher requirements for products. Due to the fierce competition in the industry and the rapid upgrading of products, the plastics industry is now facing more and more problems in injection molding processing , and the requirements for molds are becoming higher and higher. There are often customers who make problems for us on the mold, and the precision of the mold gradually increases. Below I will explain to you what should be paid attention to when designing the mold.
1: Shape and dimensional accuracy of the target molded product, resin flow direction, transmission of injection pressure, and solidification of the filled resin. As a mold designer, you must know the requirements of the product, which is also the source of precision mold design. So the requirements of the product must be well understood.
2: The characteristics of the target molded product must have a systematic list of the characteristics of the molded product, mainly in terms of materials, the shape of the molded product, and some details on the mold design below.
3: Structure of the mold. The structure of the precision mold is different from that of the ordinary plastic mold. There may be several types of common plastic mold structural design solutions, but precision molds, some structures may have a certain impact, so some precision mold structural solutions may be very demanding. The main consideration is the impact of mold action on the product.
4: The rigidity and strength of the mold. My personal experience thinks that the rigidity of the mold is very important. I often see that the mold embryo and the inner mold material are very thin. I can only say that his mold can be produced, but some of the problems are with the mold. Intensity is closely related and sometimes difficult to find. If the strength of the mold is to maintain the mold not to break, I think this is a very unreasonable idea, and it can also be regarded as a manifestation of insufficient experience in mold design.
5: The glue inlet and the horizontal glue lane are important factors for controlling the product. The precision mold has certain requirements for the way of feeding the product. Making the glue point beautiful will have an unexpected effect on the product.
6: Mold temperature adjustment circuit, the mold should be controlled at a uniform temperature. It is necessary to set a temperature difference required for the resin flow direction, and a countermeasure must be taken for the portion where the meat thickness changes. When the molded product is released from the mold, the mold surface temperature of the product part must be uniform. This requires a reasonable mold cooling system.
7: The precision of the precision mold is very high, and the processing method adopted for the processing mold is very important. According to the shape of the molded product, the cavity of the product is divided, and the slow wire is often used. Therefore, we must consider the processing method when designing.
8: The mold structure should be reasonable to facilitate the addition of other programs. For example, a position may be unsatisfactory. If it is really unsatisfactory after the mold test, a supplementary plan must be adopted.
