1 definition of mold processing:
Die processing refers to the production of blank and forming tools, in addition to the shear die and die. Under normal circumstances, the mold with the upper mold and the lower part of the two components. The steel plate is placed between the upper die and the lower die, and the material is formed under the action of the press. When the press is opened, the workpiece which is determined by the shape of the mould can be obtained and the corresponding waste material can be removed. Small electronic connector, to the dashboard of a workpiece can die molding. Progressive die is the automatic processing of the workpiece from one station to another station, and in the last station to form a set of parts of the mold. Mold processing: cutting die, blanking die, compound die, extrusion die, four slide die, progressive die, stamping die, die mold etc..
2 mold type
(1) metal stamping die: continuous die, Dan Chongmo, compound die, drawing die
(2) plastic molding: injection mold, extrusion mold, plastic mold
(3) die casting die
(4) forging die
(5) powder metallurgy mould
(6) rubber mold
3 mold processing flow
Open material: the former mold, the mold after the mold material, insert the material, the row material, the slanting top material;
Open frame: front die frame, rear die frame;
Open thick: before the mold cavity open thick, after the mold cavity open thick, parting line open thick;
Copper public: the former model of copper and copper, after the model of the public, sub - line clear angle copper;
Wire cutting: insert parting line, copper Gong, inclined top pillow;
Computer gong: fine Gong parting line, fine Gong mold core;
Electric spark: the former die thick, copper male, male die line clearance angle, after the model bone position, pillow;
Drilling, pinhole, thimble;
The water hole of the mould thimble hole is processed by the row position and the row position pressure pole;
4 other
(1) Jack Tsui, model code pit, garbage nail (nail spacing);
(2) flying mode;
(3) water nozzle, support head, spring, water transport;
(4) die, polishing, front and rear die;
(5) fine water structure, pull rod screw retractor, spring
(6) heat treatment, quenching, and surface nitriding of important parts;
5 mold software

6 basic features
(1) the processing precision is high, and a pair of dies is generally composed of a concave die, a convex die and a die frame. Therefore, the combination of the upper and the lower die, the combination of the insert block and the cavity, and the integration of the modules require high processing precision. The precision of the precision mould is often up to M.
(2) the shape of the complex products such as automotive parts, aircraft parts, toys, household appliances, the shape of the surface is a combination of a variety of surfaces, therefore, the mold cavity surface is very complex. Metal processing WeChat; mw1950pub some surfaces must be treated mathematically.
(3) the production of small batch die is not mass production, in many cases, often only one.
(4) in the process of multi mold processing
(5) the use of a repetitive mold is life - long. When the use of a mold over its life, it is necessary to replace the new mold, so the production of the mold is often repeated.
(6) there are no drawings and no data in the process of profiling die production. This requires high precision imitation, no deformation.
(7) excellent mold material, high hardness of the main material of the mold is made of high quality alloy steel, especially the high life of the mold, often using Crl2, CrWMn, etc.. This kind of steel from the blank forging, processing to heat treatment are strict requirements. Therefore, the preparation of processing technology can not be ignored, heat treatment deformation is also a serious problem in the process of processing.
According to the above characteristics, in the selection of machine tools to meet the processing requirements as far as possible. Such as the function of the CNC system is stronger, the accuracy of the machine is high, the rigidity is better, the thermal stability is better, and has the function of copying.
