Abstract
The present invention relates to a gas spraying process for gypsum-steel, which belongs to the field for manufacturing a mould. Compared with the common method for using metal spraying at ordinary temperature to manufacture injection molding moulds, the present invention has the characteristics that silicon collosol is used as surface treating agent, and a mould cavity surface is formed from the combination of powder mainly composed of nickel, chromium, boron and silicon and a high-carbon steel coating of hot spraying by adopting the cold spraying process. The steel mould manufactured by the gas spraying process has high intensity, high wear resistance, low cost, simple working procedure and short period for manufacturing moulds. The present invention is suitable for moulds manufacture with composite mould cavity and difficult machine work or electrospark work.
Description
The gas spraying process of gypsum one steel is used to make injection mold, belongs to mould manufacturing field.
Generally spraying the method for making injection mold by normal temperature metal is, on the matrix mould surface that material that easily processing and thermotolerance are low such as timber, plastics, gypsum, low melting point metal are made, coating one deck is based on the surface treatment agent of water-soluble binder (as water glass) and fabric, spray the high metal of skim hardness again, for example nickel, chromium or its alloy, then, in order to strengthen this layer metal pattern, spray layer of metal thereon again or be coated with resin.Then, will spray mould from the matrix mould takes off and gets final product.It and traditional Wimet blank of scribing, cutting or be that the working method of matrix metal mould re-plating Wimet is compared with the metal of easy processing, it has the restriction that is not subjected to complex-shaped degree, make easier, the advantage that man-hour is short, but its coating structure is mechanical bond basically, and the intensity of its sprayed coating is lower than the metal pattern of metallurgical binding, fragile, when casting,, thermal shocking also can reduce the life-span owing to producing be full of cracks.For addressing this problem, the present invention proposes a kind of gas spraying process of gypsum-steel, it is characterized in that, it makes surperficial treatment agent with silicon sol, after air-dry, brush one deck again, soon spraying one deck with the method for cold sprinkling is main powder by nickel, chromium, boron, silicon, also available Al contained Ni, air-dry then, or 120 ℃ of oven dry down, for the purpose of strengthening, spray one deck steel again on gypsum model, its thickness is 4-5mm, and second step is aluminium-plated again as weighting agent, its thickness depends on the needs, and the 3rd step sprayed the thick steel of one deck 4-5mm again.Above-mentioned is that the per-cent of main its composition of powder is by nickel, chromium, boron, silicon: the composition of nickel is 75%, and chromium is 10-20, and boron is 1.4-3, silicon is 2-4, and iron is below 10, and carbon is between 0.5-0.8, its powder size is 180-320 order/time, and powder layer thickness is below 0.5mm.The composition per-cent of its Al contained Ni is: nickel is 60-70, and aluminium is 40-30, and its powder size is 180-320 order/time, and all the other are identical.Because cavity surface of the present invention is to be the main powder and the high carbon steel coating be combined into of thermospray by nickel, chromium, boron, silicon.Nickel/silicon/boron/chromium can impel nickel, chromium etc. to spread in high carbon steel can emitting heat after the combination, thereby intensity is very high.Except that mechanical bond, show that wherein coating interface has produced little metallurgical binding, thereby cavity surface has higher wear resistance and intensity by X-ray diffraction and electron probe microanalysis.Secondly, owing to adopt silicon sol to make surperficial treatment agent, its intensity, caking ability, high thermal resistance are all good than water glass, and be more simple compared with by water glass and fabric being that the main surface treatment agent of forming comes it to form.In addition, the present invention has adopted cold sprinkling powder easier than hot spraying powder, and cost is also low.Last packing layer of the present invention is the good aluminium of thermal conductivity, and compared with the strengthening course that makes with resin or resene fiber synthetics, it more is applicable to the pad plastic material, needn't bury the cooling pipe again underground, and pattern making procedure is simple, and is easy to use.
The present invention wants to add latex earlier and stir in water when making gypsum model, leaves standstill after several minutes and removes surfactant foam, adds terra alba again and stirs, pour in the molding box.Its terra alba, the weight percent of water and latex are 55-65: 25-35: 5-15.
Embodiment:
Spray material: high carbon steel hank knotting, diameter 1.6-2.0mm;
Acetylene pressure: 0.5-1.0Kg/cm
2;
Compressed air pressure: 4-6Kg/cm
2;
Oxygen pressure: 4Kg/cm
2;
Wire feed rate: steel wire: 3-5m/min;
Aluminium wire: 5-7m/min;
Spray distance: first shell: 200-400mm;
Packing layer: 100-200mm;
Second shell: 100-200mm;
A rabbit shaped steel of spray mould, about 3-4 hour, coating thickness (steel+aluminium+steel) was 15-30mm.
The transversal figure one that meets personally of any shaped steel mould.Wherein: 1 plaster matrix film; 2 spraying moulds; 3 surface-treated layers; 4 first shells; 5 packing layers; 6 second shells.
When making, need not add the steel frame, spray and afterwards needed only with simply milling or desired shape is made in machining such as plane.
The rabbit shaped steel mould that the present invention makes, its experimental data is as follows:
Check intensity: 15-17Kg/mm
2, (make of present general method, all at 14Kg/mm
2Below).
Hardness: HRG30-35; Void content: 6-8%;
Experimental results show that: the mould of making of the present invention is compared with traditional die-manufacturing method and is characterized in: have higher intensity and wear resistance, can duplicate the decorative pattern of basic mould exactly, moulding cycle is short, cost is low, operation is simple, be particularly suitable for the die cavity complexity, during the mould that machining or electrospark machining are difficult to realize is made.
