Description
Technical field
This utility model is related to a kind of die casting heating arrangement, belongs to die casting field.
Background technology
Die casting is a kind of metal casting technique, is characterized in applying high pressure using mold cavity to the metal melting.Mould leads to
It is often to be processed with the higher alloy of intensity, some the similar injection mo(u)ldings of this process.Most of die casting foundry goods are all not
Iron content, such as zinc, copper, aluminum, magnesium, lead, stannum and terne metal and their alloy.According to the difference of die casting type, need
Cold-chamber die casting machine to be used or hot chamber machine.Existing compression casting technology is that the stress metal of melting is fed into mould
Interior, before perfusion, mould can be preheated, prevent the metal melting from condensing touching cool mould, lead to into
Product molding defect.Even if but mould is preheated, because the heat conductivity of the metal of metal is strong, can cool down rapidly, so
If the metal of melting irrigates not in time, will be unable to will be full for mold cavity perfusion, result in finished product edge occur slight
Defect is it is impossible to reach finished size requirement.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of compression mod
Tool heating arrangement, is continuously die casting heating, die casting finished product edge is not in defect.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of die casting heating arrangement, bag
Include fixed half and moving half, in cover half, be provided with cover half cavity, in cover half cavity, be provided with cover half core rod, the lower surface of dynamic model is arranged
There is dynamic model core rod, dynamic model core rod is arranged in cover half cavity；It is provided with cover half set, the outer surface of cover half set outside described cover half core rod
With the inner surface interval setting of cover half cavity, the inner surface formation heating cavity of the outer surface of cover half set and cover half cavity；Described
It is provided with heating tube between the inner surface of cover half cavity and the outer surface of cover half, cover half is provided with hot inlet and hot-fluid goes out
Mouthful, the two ends of heating tube connect hot inlet and hot outlets respectively, and heating tube includes internal core pipe, on inner core tube outer surface
It is wound with hot runner passage pipe, internal core pipe is provided with some heat pipes, the end of heat pipe is connected with buffering cavity, buffering
Cavity is arranged in heating cavity；It is provided with some thermal vias on described buffering cavity.
Optimize, above-mentioned die casting heating arrangement, in described heating cavity, be provided with some thermal insulation boards be arrangeding in parallel,
Through hole is provided with thermal insulation board.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
Design increased heating tube between the inner surface and the outer surface of cover half of cover half cavity, by the heat effect of heating tube and right
Mould is heated and is kept the temperature of mould.Because the specific heat of metal is little, heat scatters and disappears soon, increases heating cavity and passes through heating
The buffer action of cavity is heated to the inside die cavity of fixed half and moving half and is incubated, and improves heat insulating ability.In heating cavity
Setting buffering cavity, is heated to heating cavity by buffering cavity, heat insulation effect is better than directly heating.Increased heat-insulated
Plate, and through hole be increased on thermal insulation board.Steam is delivered to by top by through hole, heat in heating cavity can be increased
Uniformity, prevents bottom heat to be less than top heat it is ensured that the temperature of whole die cavity is uniform.The other structures of application, such as add
Press, pour, the structure such as die cavity, guiding identical with technical scheme of the prior art.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure：1 is cover half, 2 is dynamic model, 3 is through hole, 4 is cover half core rod, 5 is dynamic model core rod, 6 is cover half set, 7 is to add
Hot cavity, 8 be hot inlet, 9 be hot outlets, 10 be internal core pipe, 11 be hot runner passage pipe, 12 be heat pipe, 13 be
