What are the common problems of the infusion set mold in the product production process?

In order to adapt to the upgrading and adjustment of the domestic mold industry structure, my country's mold industry still needs to increase its development efforts, and constantly strive to develop middle and high-level molds to increase its output value. It is understood that in the past ten years, the output value of domestic molds has increased by about 18% every year, which is higher than the annual growth rate of my country's GPD. However, the total demand for domestic molds still exceeds supply, and the self-matching rate of domestic molds is low. Oversupply, and nearly 50% of advanced molds rely on imports, especially large, precise, complex, and long-life molds have a large gap. On the whole, my country's mold industry still needs to do its best to promote the domestic mold industry to develop its strengths and reach a higher level.

In the production process of the infusion set mold, the mold material often presents various defects and deformations: One of the reasons for material deformation is that in order to reduce costs, the material used for the actual mold is not a special mold steel, and the rigidity of the template is insufficient and the thickness is not good. Improper heat treatment and residual stress, EDM stress, etc., the above reasons often interact, increasing the amount of deformation.
In addition to the corresponding solutions during processing, widen the die feet or use afterburning columns at various points in the middle of the die to withstand. Some molds themselves are not very demanding, and can be heated and deformed at a high temperature at the focus position, which is quite effective. People often grind off the edge of the template to reduce the contact surface, and it is necessary to minimize the grinding depth to facilitate the effective life of the mold. The standard error of the cavity angle after the template is deformed is difficult to correct. The too tight core causes the cavity to be deformed by the wall. This phenomenon is particularly serious when there are multiple cavities. If it is used reluctantly, the flash in the middle of the template will not change. , especially for injection nylon and other products with good fluidity, the redistribution core should be smoothed. When the mold is trimmed, it is welded on a thinner seat, and the amount of deformation cannot be ignored.
