About the cooling problem of mould antrum, already had many articles and discuss. Manufacturer of most moulding business and die knows, mould core or model antrum collects the technology dividing heat with spent much likelihood to have profit. Get a Kong Jin simply to enter model the bottom of core is formed close the space is inserted fender or bubbly implement, can bring about quantity of heat inhomogenous. Before workpiece can be pulled out surely, this quantity of heat is in model constant temperature must be dropped in core. This kind of caloric is inhomogenous bring about model core is cooling and bad, protraction cooling time, waste already costly. As the gradual progress of engineering technology of computer simulation Injection Molding, the cooling process with moulding periodic to shaping business had more knowledge. Say simply, the product is periodic time. Be in given the work that produces by the client's norms inside time is more, the cost of every component is lower. Introduce following form refrigeration along with form refrigeration is a kind of skill that the surface that refrigerative belt is sticking moulding workpiece as far as possible takes. Move cooling zone close by the workpiece of moulding, shorten periodic time, make the refrigeration of moulding workpiece surface evener. The manufacturing business that heats up flow path system by a few establishs internal flow method to be in this system and development perfects this technology. Result, they put internal flow way inside any matrix of steel, can bear at the same time in 3D space very high in-house pressure. Before long, the client of manufacturer of these hot flow path begins a requirement its model core and model antrum is made with same method. The extremely tall frit that receives craft to make with board frit receives the benefit of intensity, it is to conduce to maintain after following form refrigeration model core and model antrum structure. It makes model core and model the water leak that the outside pressure place that antrum produces to inject and cooling phase causes is kept out more easily. This craft is OK the mould steel that frit accepts all typical cases, include 420 stainless steel, H13, S7, P20 to wait. These rolled steel when need also can frit receives makings of cupreous base material to go up, use at mixing model assembly parts. Board frit is received after finishing, the assembly parts that frit receives can do anneal, heat treatment to wait, and any other and common moulds core or model tune is same (graph 1) . What die manufacturer still can be used to habitual rolled steel with them. Grind, cut of mill, line and shape to electric spark machines a process or resemble be being done euqally usually. Their main distinction was to had finished frit is received assemble and interior shedding road is changeless. The redo after the process is finished is received in frit all finish machining. Graph 1 this is example of two patterns that are used at producing moulding to build core. Left cools with typical fender, refrigeration is passed model the center of core comes up; Right is have identical external dimension model core, but those who use is along with form refrigeration contrast bubbles implement follow form core with what take flat frit to receive: The workpiece temperature when backfill phases ends is from 165. 7 ℉ fall to 106.
3 ℉, reduced 36 ％ . Temperature of the workpiece when cooling phases ends is from 149.
8 ℉ fall to 93.
8 ℉, reduced 38 ％ (graph 2) . The mould when cooling phases ends (model core) temperature from 245.
5 ℉ fall to 118.
5 ℉, was equivalent to periodic time shortening 39 ％ . Graph temperature of the workpiece when 2 cooling phases end: From 149.
8 ℉ fall to 93.
8 ℉, reduced 38 ％ to use sell more patterns in order to help die manufacturer along with form Leng Ke. Moulding business can make work more hourly and the product that its client can get better quality with lower cost. In the light of every specific application production of use first-rate method is followed form refrigeration core and model antrum, will raise client satisfaction to spend. CNC Milling
