Precautions for designing precision molds
The shape and dimensional accuracy of the molded article of the object, the flow direction of the resin, the transmission of the injection pressure, and the solidification of the resin to be filled. As a mold designer, you need to know the requirements of the product, which is also the source of precision mold design. Therefore, the requirements for the product must be well known.
The characteristics of the molded article of the object have a systematic list of the properties of the molded article, mainly in terms of materials, and the shape of the molded article, which has a basis for some details of the design of the lower mold.
The structure of the mold. The structure of the precision mold is different from that of the conventional mold. There may be several structural design schemes for ordinary molds, but the precision molds and some structures may have certain influences. Therefore, some precision mold construction schemes may be demanding. Mainly consider the impact of mold action on the product.
The rigidity and strength of the mold. My personal experience is that the rigidity of the mold is very important. I often see that some molds and inner mold materials are very thin. I can only say that maybe his mold can be produced, but some products have problems with the mold. Intensity has a close relationship and is sometimes difficult to find. If the strength of the mold is to maintain the mold will not break, I think this is a very unreasonable idea, it can be regarded as the performance of the mold design experience.
