Q:What is the hardness of mould steel chromium 12 unquenching?
The steel of the Cr12 is annealed, the hardness is 217-269hbw, Shanghai ai liai metal material, wholeheartedly for your service.
Q:The wall thickness of the die is affected by the plastic parts
Different plastic minimum wall thickness is different, small yu this wall, even if the uniformity also cannot be done The thin wall is difficult for the top, the layout of the thimble, the big and big.
Q:What is the material of hot pressing die?
Hot pressing molding sometimes can be divided into vacuum forming (vacuum forming), and compression molding (compression will molding), the pressure is not the same way. Most of the compression molding is to put the plastic in the mold and soften it, then apply the pressure to form. And the pressure source of vacuum forming can be a unilateral vacuum, or in addition to a vacuum outside, the other side is supported by high pressure. Compared with other processing method, hot press molding has the advantages of mould cheap, uniform thickness, its products from the early military map model and the airplane engine cover, now can be made into inner liner of the refrigerator door, the car fender, automobile chassis, soft drink bottles, signs, packaging materials and its products even thickness.
Q:Is the stamping tool to be used for the precision of the stamping parts? Why is that?
The punching and falling are two different processes, although they seem to have been achieved, and the smaller ones are separated from the larger ones. The punching process, which requires the size of the detached surface of the large material, is a waste material; The drop process - the size of the small piece of material that is separated, the small material is the product. Die design of the punching process - the main die is the punch mould; The tooling that implements the localization is relatively complicated; Mold design of the blanking process - the base mode is the concave mold. Because of the emphasis on the process of punching and falling materials, the processing and placement of the material in the process of processing and resettlement are also different.
Q:What are the career prospects of the mould profession
It is understood that at present China mold enterprise is generally met a talent shortage problem, talent shortage has become the mold technology to further improve the bottleneck of further development, mould industry. The salary of mould personnel rises. Due to many enterprises difficult to recruit skilled senior technicians, lead to these people pay tends to rise, such as professional mold design of average monthly salary of 3000 yuan, nc 3500 yuan a month, familiar with design, processing, modelling the whole operation process of senior workers more than 5000 yuan a month, and the skills a good talent over ten thousand yuan a month is not unusual.
Q:How do H13 mould steel heat treatment
1. Preliminary heat treatment in the market supply of H13 steel and die steel billet, in the steel mills have prepared annealing heat treatment, ensure the good metallurgical structure, proper hardness, good processability, and no longer annealing. But factory to change after forging has destroyed the original organization and performance, stress, increased the forging must be annealed. Isothermal spheroidizing annealing process for: 860 ~ 890 ℃ heat insulating 2 h, cooling to 740 ~ 760 ℃ isothermal 4 h, furnace cooling to about 500 ℃.
Q:The effect of mould preheating and several methods of preheating
Mould temperature machine (oil) heating: the heating is even, the temperature adjustment adopts intelligent control, the temperature control accuracy is high, can meet the strict requirement of high craft standard. The operation control and safety monitoring device is fully complete, the heating process is fully automatic, the operation is simple, and the installation is convenient. Closed circuit heating, low heat loss, significant energy saving effect, no environmental pollution, wide range. The drawback is that heating is transmitted by heat, which is slower
Q:How do you buy the die?
Borrowing: fixed assets -- molds Tax payable - the VAT (input tax) Loan: bank deposit/accounts payable/stock cash Depreciation time: eliminate the residual value rate general 5%, according to 10 years depreciation So that's the original value minus 5 percent of the original value divided by 10 years divided by 12 months is equal to the cumulative depreciation of every month Above is financial calculation method, but in actual, the mould should be used according to the number for depreciation or abandoned, so to maximize utilization of assets. Of course, the mold when not in use, must pay attention to the maintenance state, not the rust or damage occurred.
Q:How do you handle the die holder
Under external force, the material is made into a special shape and dimension. Widely used in cutting, forging, cold heading, extrusion, powder metallurgy parts suppression, pressure casting, as well as engineering plastics, rubber, ceramics and other products of the molding or injection forming. The mold has a certain contour or inner cavity shape, and the shape of the blade can be separated by the shape of the outline. The inner cavity shape can be used to obtain the corresponding solid shape. The mould usually includes two parts: the moving model and the mold (or the punch and the concave), which can be divided into two parts. When apart, take out the pieces and put them into the mold cavity forming. Mold is a precision tool, complex shape, bear the expansion force of billet, the structural strength, stiffness, surface hardness, surface roughness and machining accuracy have higher request, the development level of mold production is one of the important symbol of the levels of mechanical manufacturing.
Q:What is the difference between a large water inlet and a thin nozzle?
1, before the gate is mould no separate parting mould also called junior die guide pin is installed, and fine nozzle is fixed mold has a separate classification that is a mould parting more than one time (at least 2 times) Generally speaking, the mouth of the water is a product which has more or less water in it, but the water mouth is the opposite! The top of the mouth of the large water mouth is A plate with A simplified and standard water outlet in the front mold 4, a lot of water mouth push board ~ ~ the water mouth is: more than a big water mouth to feed a push board. Large water mouth: a nozzle that is removed by manual or other means. Water port: a water port that is removed by hand or other means without the need of the rear sequence.
