What is the relation between the mould and the clamp
- How to say, big is all belong to the mechanical industry, say to the relation, I personally think to make the mold to be able to make a fixture, do jig not necessarily can make the mold. The mold needs more experience, and the fixture needs more creative thinking. The common fixture is non-target, but the mold is not the standard, but is roughly the same type. Such as stamping die of blanking die, the structure is basically all the same, just in the middle of the blanking shape, templates, fixed plate, stripper plate up and down, up and down mold core, unloading spring, guide pin guide sleeve is involved. There are many different types of jig, but the key is to locate and clamp these two core ideas. Ok.s
What is the manufacturing of mould materials
- Mold material is very wide, there are steel. Copper alloy. Aluminum alloy and so on metal materials, also have wood. Gypsum. Plastic etc. Nonmetal material, so make it industry is also widely, such as using a standard steel belongs to steel industry; The materials used in non-ferrous metals shall be in the casting industry; For example, the wooden model of casting is in the wood industry and so on.s
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.s
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.s
What is the pull mold
- Drawing die: In the case of metal cold stamping books, the "drawing die" is usually the "drawing die" or "stretching mode". In the process of drawing, the parts of the non-spreadable surface are stretched or stretched, so the deep die is also known as tensile or draw-down mode. The drawing die is the norm, and the stretch or pull model is an alias, no difference. The typical structure of a draw-down model The complicated overlays must be double-acting press. This is due to: (1) single action press of the clamping force is not enough, there are air cushion of single action press the clamping force is equal to the pressure of press ~ 25 ~ 20%, and outside of double-action press slider clamping force for the slider pressure within 65% ~ 70%. (2) the clamping force of the single action press can only be the entire adjustment, and double action press slide block outside pressure available outside the four corners of the slider, high and low adjusting nut to adjust, by tilting the slider, adjust the moulding material on each part of the force that press a material, control the flow of the material surface material. The pull of single action press is not enough. (4) single action drawing die of the pressure plate is not rigid, if pressure is expected to face is the three-dimensional curved surface shape, at the beginning of the drawing when bending into pressure burden surface shape because the pressure of material surface shape asymmetry pressure plate deflection, serious when pressure is lost.s
Make the mold with the dough
- Don't know what material are you going to make up, but the estimate is made of liquid class can be solidified material. So note that, if the material to be heated to a liquid to prevent the high temperature burn silly putty cavity (silly putty is usually made of flour and salt). In addition to prevent leakage of liquid. (recommended materials choose gesso)s
What is the difference between a mold and a handboard?
- Although there are so many differences between planks and mould, but they still have contact, generally use hand-board model to the customer to confirm the shape first, confirmed to open mold production. The cost of many physical molds is generally high, with large molds valued at 100,000 or even millions, especially in the medical industry. If there is a structural unsound or other problem in the process of installing the die, it will be very large. The handboard model can solve the problem of this loss, reducing the risk of making physical models.s
