Problems solved by technology
[0002] The piston hole of the valve seat injection molded part is usually processed and formed through the cooperation of the main mold and the core mold. Since the piston hole of the valve seat injection molded part has a dynamic sealing requirement, the roundness requirement for the sealing section of the piston hole is very strict; The complex structure leads to large deformation after injection molding, and the piston hole is usually deformed into an irregular oval shape, which cannot meet the sealing requirements; in the prior art, the reverse deformation compensation method is usually used to compensate for the design of the core mold, but Since the sealing part is a section, the deformation of different positions is not the same, so the effect of the existing compensation method is not ideal

The invention discloses a segmental compensation design method for a valve seat mold, which includes steps such as random sampling, segmentation of the sealing segment, selection of measured points, measurement of the measured points, and establishment of a compensation core model. The sealing section is measured in sections, and the core mold is designed for section compensation according to the error data, so as to improve the accuracy of the core mold, greatly improve the roundness of the piston hole of the product sample, reduce the leakage in the piston hole, and improve the product qualification. Rate and production efficiency, reduce production costs, and improve corporate competitiveness.
