Selection of mould production mode
The mold production of small batch parts adopts single piece and prefabrication. Large-scale complete production of parts. If the same part product needs to be completed by multiple molds, continuity should be maintained when processing and adjusting the molds.
Characteristics of mold manufacturing
There are many processing contents in the same process and the production efficiency is low. Workers are required to have a higher technical level. The size and position of some working parts of the mold must be determined after the experiment. After assembly, the mold needs to be tested, adjusted and repaired. Mold production cycle is generally longer and the cost is higher. Mold production is a typical one-piece production, so the production technology, management mode and manufacturing technology all have unique regularity and particularity.
Mold production steps
Mold pattern design includes mold assembly drawing and part drawing. Making the process specification is to make the processing technology and operation method of the whole mold or part and fill in the process card. The production of parts and components is to process parts and components according to the process drawn up on the process card. Assemble. Die Trial and Adjustment Try to adjust and correct on the press until qualified parts are produced. Check the packaging appearance, make records, and package another product with the mold.
Technological method of die processing
Casting processing zinc alloy castings, low melting point alloy castings, beryllium bronze castings and synthetic resin castings. Cutting processing: ordinary machine tool processing, copying milling processing, forming grinding processing and carving, CNC machine tool processing. Special machining EDM (EDM, WEDM, electrolysis) corrosion machining ultrasonic machining. The purpose of rough machining is to remove most of the allowance. Finishing makes the workpiece achieve higher machining accuracy and surface quality. Finishing and polishing, grinding guide posts and guide sleeves.
Basic requirements of mold manufacturing process
Ensure the processing quality. Guarantee the manufacturing cycle. Ensure low cost. Improve the technical level. Ensure good working conditions.
