The most common method and process of plastic mold development and design
Plastic mold development design and processing commonly used processing tools and machines
1) measuring tools: caliper, micrometer, micrometer, standard measuring block, standard Angle block, rotary table, Angle gauge, projector, counting machine, etc.;
2. Processing machines and equipment: gongs, lathes, grinders, drilling machines, CNC (computer gongs), sparks, wire cutting machines, etc.
3) processing method and technology
Generally the moulds are ordered directly from the moulding plant and the processing methods are omitted here.According to the design drawing of precision injection mold processing, we can order back the mold embryo, mold kernel, row position, inclined top, insert and other steel materials to arrange precision injection mold processing.According to processing technology, it can be roughly divided into two parts: rough processing of precision injection mold and fine processing of precision injection mold.The mold embryo opens the frame, by the gongs bed or the computer gongs first opens the thick, then the refined frame (may also be processed by the mold embryo factory, but must pay the corresponding fee;Some small mold shop to save costs tend to processing, but low efficiency, accuracy is not high), the other part was also the first plastic mold development and design rough machining into coarse embryos, after computer gongs, cremation machine, line cutting machine processed to meet the requirements of the drawings precision parts, final assembly into the mold to become a complete set of mold.The process is roughly as follows: mold opening frame, mold kernel, line and other CNC processing, copper processing, lighter processing cavity (EMD) locksmith processing (FIT mold), polishing (save mold), loading and testing.
In the actual manufacture, several kinds of plastic mold development and design processing technology are interwoven together, which requires the plastic mold development and design personnel and mold master to arrange each link.Rework often results in damage to the mold, resulting in precision injection mold processing is not beautiful.To make up for it, you can only change the material, which will increase the time and cost, and in many cases time is the most important.Now precision injection mold processing industry competition is very intense, customers are very urgent to die room time, can not be delivered on time, will eventually lose customers!
Function introduction of each machining equipment:
1. Gongs bed, used for manual milling and cutting of workpieces with simple shapes and rules, such as straight and diagonal lines;Usually used to process not very high accuracy of the workpiece, mold opening frame, mold kernel, line opening materials.
2. Lathes are mainly used for the processing of circular workpieces, such as nozzle, positioning ring, flange, circular mould CORE, circular copper male, etc.;High accuracy is required.
3. Grinding machine, mainly used for grinding of steel materials, grinding standards, etc., can meet most of the precision requirements.
4. Drilling machine, mainly used for drilling air, tapping and water hole, etc.
