Introduction of mold manufacturing characteristics?

(1), the characteristics of mold production

Mold manufacturing technology focuses on many technologies of mechanical processing, which can not be combined with electromechanical processing without the manual operation of locksmith. ① Selection of mould production mode A) The mould production of small batch parts adopts single piece and material preparation. B) Complete production of parts in large quantities. C) If multiple molds are needed to complete the same part, continuity should be maintained before and after mold processing and adjustment. ② Mold manufacturing features: a) There are many processing contents in the same process, and the production efficiency is low. B) Workers are required to have a high technical level. C) The size and position of some working parts of the mould must be determined after the experiment. D) After assembly, the mold must be tested, adjusted and repaired. E) General molds have long production cycle and high cost. F) Mold production is a typical one-piece production, so the production technology, management mode and manufacturing technology all have unique regularity and particularity.

(2), the steps of mold manufacturing

① Mold pattern design includes mold assembly drawing and part drawing. (2) Formulate process specifications, that is, formulate the processing technology and operation method of the whole mold or part, and fill in the process card. (3) The production of spare parts is to process the spare parts according to the process drawn up on the process card. ④ Assembly. ⑤ Trial adjustment Try to adjust and correct on the press until qualified parts are produced. ⑥ Check the packaging appearance, make records, and package another product with the mold.

(3), mold processing technology

① Casting processing zinc alloy casting, low melting point consensus casting, beryllium copper consensus casting and synthetic resin casting. (2) Cutting processing: ordinary machine tool processing, copying milling processing, forming grinding processing, carving, and NC machine tool processing. ③ Special machining EDM (EDM, WEDM, electrolysis) corrosion machining ultrasonic machining. ④ The purpose of rough machining is to remove most of the allowance. ⑤ Finishing makes the workpiece achieve high machining accuracy and surface quality. ⑥ Fine grinding, polishing and grinding of guide posts and guide sleeves.

(4), the basic requirements of mold manufacturing process

① Ensure the processing quality. ② Ensure the manufacturing cycle. ③ Ensure low cost. ④ Improve the technical level. ⑤ Ensure good working conditions.
