Injection mold. What does the soft mold mean? What's the difference between a quick one?
It's soft molds!! Soft mold forming using rubber mold modification, manufacture simple, low cost, the surface is not easy to scratch, but the pressure loss is big, the rounded part of workpiece forming difficulties, not suitable for complex shape and depth of the workpiece. Hydraulic forming can eliminate the above shortcoming, but when the liquid is directly applied to the workpiece, it is very important to solve the sealing problem. Hydraulic - rubber mold forming, can overcome the defects of these two kinds of soft moulds, forming various kinds of complex shapes. When drawing the shape parts of a deep curved surface with rigid punch, there is no free surface area of contact with the convex mold, and the stress state is a tension, and it is prone to wrinkle. The stress state of the molds is bidirectional tensile stress, which eliminates the cause of wrinkling. Soft mold forming and soft concave model two kinds. It is used for forming large flat and small parts, the main disadvantage is that the middle part of the billet is easily thin. When the liquid is convex, the stability of the raw material is not good and easy to deflect because of the frictionless friction between the liquid and the billet. Soft concave die can be used to form complex depth larger workpiece, due to high pressure, the effect of billet is tightly covered in punch, not only accurate positioning workpieces, and have the effect of the auxiliary forming, expanded the possibility of forming parts time; In addition, the mould general use is big, the structure is simple.
A soft die is a concept that is relative to a hard mold. In the process of component design generally need to verify the design of plastic parts is reasonable, can meet the requirements of the assembly and product design changes may need to be kept. This way, we need to open a sample molds before mass production. Until the design is no longer changed, the initial mass production is limited to a single hole of capacity, which requires a large cavity. In the comparison between soft and hard models, the soft mold is not as good as the hard mold (which is the die life), except for the steel choice. What do you mean by a quick form that you don't understand? Is it a plastic block? If this is the case, then a quick form is not needed, but only a few or dozens of samples can be done, and the cost is high. The average life span of a soft mold is no less than 50,000 modules, even higher. If batch not small plastic parts, often one a hole to use soft model completely can satisfy capacity.
