模具专业英语

章节摘录

　　Irrespective of the machine tool or technique used to manufacture the various parts of the mold， the final responsibility for the finishing of the individual parts and for fitting them together lies with the bench fitter. The various stages in the bench fitting involved in the manufacture of a simple mold are listed as follows：　　1. Finishing the impression　　When the mold plates are received from the machine tool section， the impression form on both sides is in the rough machined state. Cutter marks， burrs， etc.， are very apparent on the surface. The bench fitter's first job is to produce a cavity and core free of machine marks and to the shape and dimensions specified on the mold detail drawing.　　2. Aligning cavity and core　　This operation is to align the two parts with respect to each other so that the molding produced will have the correct wall section. This is achieved by using packing pieces between the cavity and core.　　The two mold plates are clamped together and returned to the milling of boring machine to have guide holes bored through both plates. When this operation is complete， the clamps are removed， the mold plates separated and the guide pillars and guide bushes fitted. The two mold plates are again brought together and checked to ensure that the core is in alignment with the cavity.　　3. Bedding down　　This is the process of "marrying" the two opposing mold halves together to prevent the plastic material escaping between the two surfaces when the material is injected into the impression.　　……
