Q:Mold design and manufacturing to learn which courses
This major is mainly aimed at machinery manufacturing, and develops the design and manufacture of cold stamping die, type cavity mold and its design and manufacturing. Main courses: mechanical drawing, mechanical design basis, electrician and electronic technology, engineering materials and heat treatment, mould manufacturing technology, mould CAD/CAM. Jobs: workers, molds manufacturing personnel, mechanical maintenance personnel, production management personnel. Tuition is too expensive This is a professional professional, and it's easy to find a job. The school that runs this major is very few in the vocational technical college Jobs: workers, molds manufacturing personnel, mechanical maintenance personnel, production management personnel.
Q:How long is the life of die casting die?
Die casting materials used in aluminum, zinc, magnesium, copper, die die core materials also have domestic 3 cr2w8v, 4 cr5mosiv, Japan imports of SKD61, DH - 31, DAC and so on, such as the United States have H11, H13, Sweden 8407 and 8418, and 2344 W302, and so on various brands, production materials used and the mold core materials affect the service life of mould, even with the same kind of alloy and mold core material, affecting the service life of die and the structure of the product shape and so on, so can't general said that the service life of die mold how much, die from tens to hundreds of thousands of times
Q:In die mold, is it better to use UG or PROE?
If it's a product design it's better to use proe. If you're doing mold design or programming I think it's better to use ug. The ug submodule, which is fast enough to unplug the electrodes, and the ug external technology is very mature, and the unplugged electrode is automated in the way out of the material. Mold design main push UG. There is a high degree of UG promotion. Software updates are fast, and someone might say that software updates are too late. Update quickly indicates that software companies have the money to be able to do so. It's good to learn a version, like 4.0. Although there were 5.0, most of the factory software was not updated, and computer hardware couldn't keep up. The UG mould library is full of information and is commonly used in the dragon card mould library.
Q:What certificate does the mold major need to take an examination?
Mould CNC processing programming: in addition to individual enterprises, general stamping die designers design molds without CNC programming. While the injection mould designer is in the mould design, there are many examples of numerical control programming. In general, die designers do not have numerical control programming. The task of programming is done by a CNC programmer who specializes in programming. The programmer analyzes the tasks that need to be processed by nc machine tool, and then, according to the situation of the factory, the suitable procedure is written to the processing workshop. Normally, the program is sent to the mold manufacturing workshop within the specified folder. Mould manufacturing and manufacturing process: in the manufacturing process of mould manufacturing and the use of mould, various problems are encountered. This is especially true when a new process is enabled. Selection of machine tool, cutting tool selection, the selection of cutting parameters, the selection of cooling fluid, the feeding speed, allowance, the knife, how to position when heat treatment, etc. The problem is, how to detect, mould making decisions often need to process engineers.
Q:What is the difference between mould injection and blow molding?
Blow molding: also call hollow blow molding, a kind of development rapid plastic processing method. Thermoplastic resin by extrusion or injection molding of plastic parison tube, hot (or heated to softening state), put in split cavity, mold closing immediately after ventilation with compressed air within the parison, make plastic parison swell and clingy wall in the mold, the cooling mold release, the products have all kinds of hollow. Blown film manufacturing technology on the principle and hollow blow molding is very similar, but it does not use the mould, from the perspective of classification of plastics processing technology, molding process is usually included in the extrusion of blown film. The blow molding process was used in the production of low-density polyethylene small bottles during world war ii. In the late 1950s, with the development of high density polyethylene and the development of blowing and molding machine, blow molding technology was widely used. Hollow containers can be up to thousands of litres, some of which are computerized. It is suitable for the plastic polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the empty container is widely used as an industrial packaging container.
Q:How do the plastic molds sew
In the case of the building Lord, all the moulds have a lot of wind, which is that the injection molding machine is not enough
Q:The function of die water board?
The structure of the nozzle is mainly used for the inlet of the gate.
Q:Do machine parts need to be moulds?
The parts of the machine are not required to open the die.I hope my answer will help you.
Q:The effect of mould preheating and several methods of preheating
Natural (coal) gas heating: a widely used method. Applicable to different mould shapes. The heater is made of pipes, and there are many small holes in it, and the gas is ejected and the size of the fire can adjust the air valve to achieve it. Clean without pollution, can be heated locally. The disadvantage is that it is controlled by people, and it is easy to burn the mold.
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.
