Q:The stamping dies at the Angle of 90 degrees, the Angle is big or small how to repair.
That r Angle is on the bend and it's still on the bend. ? On the bend.I hope my answer will help you.
Q:How can silicone and glass steel molds be glued together
Make plaster mold silicone mold cost is higher, soft silicone mold die, must be listed hard mold industry is hard glass fiber or plaster mold to play a role in the tray, so the cost in terms of silicon rubber, no doubt, the cost will be higher. But FRP mould, despite the cost is relatively low, but because it is a hard mold, difficult mold, also must do slice mode, there are few FRP mould is not very complex, which makes them very trouble. The silicon rubber moulds, on the other hand, are easy to make, prone to mold, and very fine molds, which make the head even a hair.
Q:Why is the mold selected for quenching?
This is mainly due to the steel in the range of the solid as the change of heating temperature and cooling speed, organization structure change, so the use of different heating temperature and cooling rate to control or change the organization structure steel, can get different performance. (a) prepare heat treatment, annealing, normalizing heat the steel to the phase transition point above a certain temperature, heat preservation time, and then slowly along with the furnace cooled to 500 'C below, after cooling in the air. So you get an approximate equilibrium organization, and it's called annealing. The so-called positive fire is to heat a piece of steel to a certain temperature above the point of phase change and then remove it from the furnace and cool it in the air. Annealing or normalizing and technical requirements of the parts service condition has no direct relation, but simply brought by the procedure in order to improve the defects, and organization prepare for the next procedure, make the grain refinement, eliminate the internal stress of normalizing, annealing, etc. When the fire is hot, it cools quickly; Slow down when annealing. Annealing reduces the hardness of the material; Positive fire can improve the hardness of the material. After normalizing steel hardness is larger than that of annealing steel hardness is high, so in order to facilitate machining, the carbon content of high carbon tool steel materials such as using the annealing treatment. In order to reduce the hardness.
Q:Is the slanting and shoveling chicken in the mold the same thing, shoveling the chicken? Where is it used?
I have never heard of what it is called The main function of shoveling a chicken, which is also called a slider lock block, is to compress the slider There is another type of spatula in front of the former mold which is the top of the chicken It's double insurance on the back
Q:What is the design philosophy of the mould?
The domestic development situation of facing the 21st century, the enterprise to adapt to the development of market economy, as the national support industry of the automobile industry will increase production of light, the micro, cars, thus puts forward higher requirements on the precision of the die forgings. In the process of production, improving die life is a complex and comprehensive problem. All forging technology, especially the net net shape and approximate shape processing technology, to a large extent depends on the precision and quality, mould depends on the skill level of the mould. Mould technology is reflected in die design and manufacturing, and die life is related to the use of the process. ? Is of great economic benefit to improve die life, generally in the trial production mold tooling costs accounted for about 25% of the cost of production, and finalize the design production is only 10%.
Q:How many products can a mold make?
Normally we do molds if the customer can live up to 50W according to the steel materials we recommend It has to do with the steel strength of the main material and the thickness of the steel
Q:What does it mean to have a rough die
The tool is used to process the rough shape of the mould. And the machine tool and cutter that open coarse use is less accurate, such processing speed is relatively quick. It needs to be left with a residual amount, and then replaced with a processed machine tool and tool. Die strategy: Follow the perimeter: less knife, more clean blade, more empty blade, suitable for electrode processing, avoiding the phenomenon of the cutting of the knife in electrode processing. Follow the workpiece: it is not easy to cut, the way is safe, it is suitable for steel material processing, lifting the knife.
Q:What is the difference between a mold and a handboard?
Hand, is simply the sample of the product, after your design drawings, design products generally can't be perfect, can't even use, direct production once the defective will be scrapped entirely, greatly waste of manpower and material resources and time. And hand in general, is one of the few samples, short production cycle, loss less manpower, quickly find out the shortage of the product design and improvement, provide sufficient basis for product production. Because of this, some places and call it "the first board", is the first sample products, that is, more image description of the meaning of the plank, and in Japan, hand and is called the "hand", its English name is "rapid prototype". Molds are a kind of production tool that can produce parts that have certain shapes and sizes. People also is usually said mold, such as TV sets, telephone shell, plastic buckets and other products, is the software into a mold cooling injection molding plastic heating. The steamed rice cooker is also made of a metal plate that is pressed into this shape. Everything is made out of molds. You can say that there is no production without molds
Q:The role of cryogenic processing of die material
The continuation of cryogenic treatment after quenching workpiece cooling process, the application in the mold industry mainly embodied in the cold work die steel and high speed steel, bearing steel, cold work mould and mould parts have cryogenic technology application case.
Q:How many types of molds? Please help me out!
Die, forging die, stamping die, aluminum casting (casting) using the block, wax mold, plastic mold, metal mould, plastic forming with modeling profile (profile), pressure molding die, glass blowing blowing mould,... This is for use. Cold/hot mold; This is divided by temperature. There is steel die, aluminum die, hard alloy mold; There are wood, sand and wax models; With a plastic mould; This is part of the material that makes the mold. There is a one-off model, multiple sex dies; Permanent model This is from the service life. There are mechanical moulds, space moulds, plastic moulds, building dies, and... This is part of the industry. There can be other calls, there is no uniform rule.
