Q:Injection mold. What does the soft mold mean? What's the difference between a quick one?
It's soft molds!! Soft mold forming using rubber mold modification, manufacture simple, low cost, the surface is not easy to scratch, but the pressure loss is big, the rounded part of workpiece forming difficulties, not suitable for complex shape and depth of the workpiece. Hydraulic forming can eliminate the above shortcoming, but when the liquid is directly applied to the workpiece, it is very important to solve the sealing problem. Hydraulic - rubber mold forming, can overcome the defects of these two kinds of soft moulds, forming various kinds of complex shapes. When drawing the shape parts of a deep curved surface with rigid punch, there is no free surface area of contact with the convex mold, and the stress state is a tension, and it is prone to wrinkle. The stress state of the molds is bidirectional tensile stress, which eliminates the cause of wrinkling. Soft mold forming and soft concave model two kinds. It is used for forming large flat and small parts, the main disadvantage is that the middle part of the billet is easily thin. When the liquid is convex, the stability of the raw material is not good and easy to deflect because of the frictionless friction between the liquid and the billet. Soft concave die can be used to form complex depth larger workpiece, due to high pressure, the effect of billet is tightly covered in punch, not only accurate positioning workpieces, and have the effect of the auxiliary forming, expanded the possibility of forming parts time; In addition, the mould general use is big, the structure is simple.
Q:Why does the mold exhaust, so where does the gas come from
There are several main sources of the gas in injection molding mold: the air in the cavity and the pouring system; The water vapor produced by the evaporation of water from the plastic material. Gases produced by plastic decomposition at high temperature; Gases produced by certain additives in plastics or chemical reactions, such as thermosetting plastics, are often produced by chemical reactions.
Q:Is the digital control the same as the mold? If not, what's the difference?
CNC is short for computer numerical control can also be called CNC is the operator input according to drawing processing program through computer processing, to send signals to the controller, the controller issued a directive driven motor motion of a device, it is widely used in modern machine tools, Mold, could be called the "father" of the product, because most of the industry, including daily life things are completed by mold, such as we drink bottles, glass He is prior to the shape of the product on the nc machine tool processing good, then through injection molding machine casting, The two are related but not the same thing
Q:The application of hydraulic cylinder in mould
Slide block, core. Some places are for the convenience of the model, some places are for release.
Q:What is a mold bite
Is lousy skin grain, a lot of plastic parts surface is very thick leather grain, like a car instrument on the stage or storage battery mirrors, etc., fine grain with spark machine can play out, but do not to come out of coarse grain, you need to use chemical liquid will need mold cavity rotten into grain, also called texture
Q:What certificate does the mold major need to take an examination?
In the process of mould manufacturing and assembly and debugging, mold designers need to participate in partial or whole modification scheme, until the end of mould can produce qualified products, mould acceptance. Mold simulation analysis: in mould design, according to experience and general principle, mold designers have a basic idea of mold structure. Is this mold able to produce qualified products? In practice, numerous factories have failed in different forms and degrees. Serious when, the mold cannot produce qualified products, even if spend a lot of manpower and outsourcing cost, even to design and manufacture the new mould, still unable to produce qualified products, project complete failure. When you meet the difficult mold should use CAE this effective weapons, analyze the possibility of various mould validation, find out the most reasonable mould structure and process solutions. This step is to optimize the mould and validate the mould design. For stamping die, for example, we use the Stamp Engineer analysis (we also use for a long time before Pam - Stamp), analyze the possible variant comparison, finally find out the most reasonable mould design scheme. The optimization and validation of the mould design scheme greatly improved the success rate. The time of die adjustment is greatly reduced, not only saves time, but also saves a lot of unnecessary trying and repairing cost.
Q:Make cell phone lens what mould material is best! ?
NAK80 should be fine. I've been using it for five or six years, and it's not your material
Q:Which of the dies is movable
Mold is fixed before, so also called in front of the fixed mold, mold finish after open mold - out - clamping and a series of movements, after mold also called dynamic model,
Q:What is the difference between the electric casting mould and the CNC working mould
Electroforming mould cavity is electricity casting processing, is to do a the same electrode and the product shape, with a thick layer of metal plating electroplating way, down to do mold cavity, general decorations in this process. CNC is also called processing center, which is the direction of computer control tool, which can be processed into very complex shapes, most of which are processed in this way
Q:What is die parting face?
A mold term. Mould is, generally speaking, there are two major components: dynamic model and fixed die (or male mold cavities and cores), parting surface is closed and state can contact between the two parts, is divided into the workpiece or mold parts mold parting plane of block size, has a broader significance. The design of fractal surface directly affects the quality of the product, the difficulty of mold structure and operation, and is one of the key factors in the success of die design. The following principles should be observed when determining the parting surface: (1) make the mold structure as simple as possible. If you avoid or reduce the side parting, you will reduce the movement of the type and the fixing of the mold to reduce the difficulty of processing. (2) it is helpful for the smooth removal of plastic parts. As long as the mold is left to be left on the edge of the moving die to make use of the top of the injection molding machine, avoid the long distance core to reduce the size of the die. Ensure the precision of the product. To minimize manufacturing and assembly errors, as far as possible, in the same module as possible. (4) not affecting the appearance of the product. The flying side inevitably occurs at the parting surface, so avoid the design of the parting surface on the smooth surface. (5) ensure smooth exhaust of the cavity. If the fractal surface is as close as possible to the final filling of the cavity wall, it can be used to exhaust the cavity.
