Description
Technical field
This patent relates to a kind of water-cooling apparatus, relates in particular to a kind of water-cooling apparatus that is used for hot runner mould.
Background technology
Injection mold is an important process equipment of producing various industrial products; Along with plastic mould design industry developing rapidly and plasthetics aviation, boat too, the applying of industrial departments such as electronics, machinery, boats and ships and automobile; Product is to the requirement that requires increasingly high, traditional plastic mould method for designing can't adapt to model change and improve the quality of mould.The computer aided engineering technology become these weak links in plastic cement products exploitation, mould design and the product processing the most effectively by way of.
The hot flow path technology is meant that the plastics that are sent to cast gate from the injector nozzle remain molten condition, when each die sinking, does not need it is solidified as waste material to take out, and the melt that is trapped in the running gate system can be injected into die cavity next time when injecting.Temperature control system in the hot runner mould comprises heating system and cooling system.The effect of heating system is to keep the plastics in the runner to be molten condition, and the effect of cooling system then is the exchange heat of accomplishing between plastics and the mould.Temperature can not be crossed lowly or too high in the heating system, and temperature is low excessively, and plastics can form thicker cured layer in runner, and influence realizes injecting continuously; Temperature is too high, possibly cause plastics to decompose variable color, on plastic, forms defective even scraps, therefore should strict temperature control.Electrical heating elements commonly used has bar type heater, tube heater, baffle heater and spiral type heated device etc., chooses the heating element heater of different size according to the different heating position.Thermocouple is a temperature element, is displays temperature exactly, and thermocouple should seal and be installed in the highest zone of temperature in the mould.
The design of cooling circuit need be considered the shape of product, factors such as the kind of cooling medium, temperature, flow velocity, cooling tube layout.All there is cooling pipe system on the surface of mold cores and cavity block, on central template, is provided with auxiliary cooling pipe, to drain the inevitable radiant heat from TOP-TIP.Cooling pipe preferably adopts the method processing of boring, and good non-edge is pieced together core to adopt firmness.
Since the complex structure that cold flow arrives, the apopore that therefore a plurality of inlet openings can be set and be connected with the inlet opening at the template side.Usually, the template side has the individual even more hole of twenty or thirty, and half is the inlet opening for these holes, and half is an apopore.As shown in Figure 1, each inlet opening connects a water inlet pipe, and correspondingly, each apopore also connects an outlet pipe.Like this, just have tens pipelines on the next door of mould and twine numerous and disorderly complicacy each other.In case wherein a pipeline has breakage, it is all inconvenient to dismantle, change this pipeline.
