Q:What is the cooling system of the mold
Exactly, the thermostat system of the mold should be called. Cooling, it's just part of this constant temperature, and the other part is insulation. In the process of injection molding, according to the material, the requirements for the mould temperature are different. For example, PP material, the temperature requirement of the mold is not high, the circulating water cooling is ok, it is ok to keep room temperature. But some materials, such as PC, require that the temperature of the die need to be kept above 80 degrees, which requires the temperature of the temperature machine to warm up the water. There are some special materials such as PPS (PPS) to demand a higher mold temperature above 150 degrees, also need the oil temperature machine or electric heating rod to heat the mold. Thermostatic system generally is in the mold cavities internal hole, forming one or more than one closed loop pipes, hoses, a into a mission of water flow in the pipeline, to keep the temperature of the mold temperature is constant. This is the die water. The other is the heating rod, which is inserted into the molds of the molds to keep the temperature above 100 degrees. It should be said that most of the moulds should be made by water, and no water will affect the life of the mold, mainly by the effect of injection molding process.
Q:The stamping dies at the Angle of 90 degrees, the Angle is big or small how to repair.
The recommended answer is quite different. Bending 90 degrees is supposed to have both internal and external conditions. The inside is less than 90 degrees, and the outside is greater than 90 degrees. This is the question of the gap and the rebound. This is in the normal model domain. General modulators and mold engineers know how to handle it. R and not R also affect this. In the case of the block under zero, the probability of a general Angle is reduced. But absolute zero is bad, can cause product scratches serious. Typically, the master moduler will be a little bit more angular, and if you do a zero, he will also get around R0.2. The solution to this problem is one packet of R processing. Adjust the bending clearance. 3 below the forming block. The moulding male is left straight after two to 3 degrees. Adjust bending clearance and so on. This is the basic problem of stamping die! I didn't elaborate on what to do, but if you were doing molds, according to the ones I was talking about, it would be easy enough to fix the problem. There are several other forms of prototyping. Each has its own merits. You know, it's not a good idea.
Q:What courses are required to learn the UG mould design?
I was learning ug there, and I had to go back to study for a while.The ug is a tool, the mould design is the process, can not be confused.
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:What is the role of the grooves in the guide column
Located, and there is an inverted Angle, preventing the separation of the positioning column from the module
Q:The plastic mould automatically dies and the product drops when it falls
You can't use the manipulator, the transmission belt is not even more. It's not possible to have a secondary top out, it's a problem that comes out of the top, and you've already written it yourself. A little want to buy something not give money, ha ha. Or semi-automatic. Use hand. Or you can try. Put slope slide board is a bit at the bottom of the mould, manipulate are placed at the side and operation side. When fall apart to make more hole products. Slide plate as close to the mold below (should consider a safe distance) to reduce product drop height.
Q:What is suitable for moulding steel
Mold steel belongs to the special steel, it is the steel which makes the mould such as cold stamping die and hot forging mould. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio meters and electrical appliances. Steel mills make steel by adding special elements to steel. The mould steel can be divided into (cold making die steel), (heat making mould steel) and (plastic mould steel) 3 kinds, for forging, stamping, cutting, die-casting etc. Because of all sorts of mould USES different, complex working conditions, so the mold steel, according to the working conditions of mold manufacturing, should have high hardness, strength, wear resistance, enough toughness, and high hardenability, hardenability and other process performance. Because of the different kinds of USES, the working conditions are complex, so the performance requirements for the die steel are different.
Q:Injection mold. What does the soft mold mean? What's the difference between a quick one?
A soft die is a concept that is relative to a hard mold. In the process of component design generally need to verify the design of plastic parts is reasonable, can meet the requirements of the assembly and product design changes may need to be kept. This way, we need to open a sample molds before mass production. Until the design is no longer changed, the initial mass production is limited to a single hole of capacity, which requires a large cavity. In the comparison between soft and hard models, the soft mold is not as good as the hard mold (which is the die life), except for the steel choice. What do you mean by a quick form that you don't understand? Is it a plastic block? If this is the case, then a quick form is not needed, but only a few or dozens of samples can be done, and the cost is high. The average life span of a soft mold is no less than 50,000 modules, even higher. If batch not small plastic parts, often one a hole to use soft model completely can satisfy capacity.
Q:What is the difference between a large water inlet and a thin nozzle?
The difference between a large water inlet and a thin water nozzle: 1, from the entrance of the entrance to the glue mouth: one is the point gate (directly from the product to the glue) usually called the thin nozzle mold; One is from the side into the glue, gate is relatively big usually call gate mould (but sometimes think products turn into the glue need will do fine shuikou gate into the glue, structure and three board mould) Different from the structure of the mould: the two plates are usually called the large water port molds. There are two kinds of thin water mouth mould and thin water mouth mould.
Q: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)
