Description
Technical field
The utility model relates to a kind of injection moulding apparatus, particularly a kind of injection moulding apparatus with cooler.
Background technology
Under normal circumstances, for the production of the mould of plastics, be all generally be made up of materials such as the alloys of steel, stainless steel, aluminium or copper.Various requirement that these materials can meet mold materials is as thermal conductivity, intensity, hardness, machining property, durability and economy.Mould generally includes two half modules and internal mold.When die body closes, between two half modules, form a die cavity.Die cavity defines the shape of product.
The built-in electric heating tube of mould is used for the resin transferring heat to melting.When mould is opened, after becoming mould parts to cool completely, released by mechanical pins or other ejecting device.The time of device cooling is determined by the performance of the cooling system of mould.Traditional mould is provided with a series of hole, and cooling fluid flows through these holes, is taken away by the heat in mould.Hole transversely and genesis analysis.These bore hole systems that are parallel and serial, receive the restriction of conventional art, such as: bore process.Bore process usually can only straight line boring, and for some nonlinear holes, prior art can not realize, and what this just made into mould parts can not realize uniform heat exchange.
Summary of the invention
The purpose of this utility model is to provide a kind of injection mold with cooling device, can with become between mould parts to carry out uniform heat exchange, thus mould parts can be cooled to uniformly.
For achieving the above object, the utility model adopts following technical scheme:
With an injection mold for cooling device, comprising: dynamic model, a cover half and a mold base; When dynamic model and cover half close, middle formation die cavity.Die cavity is provided with upper surface and lower surface.The bottom of cover half is the structure of hollow, and die cavity lower wall has certain and homogeneous thickness.Be provided with multiple first dividing plate and second partition in cover half bottom, the first dividing plate and second partition intersection are arranged on mold base, and mold base and cover half are sealed by sealing device, between multiple first dividing plate and second partition, define multiple cooling liquid flowing channel.Mold base is respectively equipped with coolant fluid import and cooling liquid outlet.
Preferably, described die cavity lower surface has certain curve radian, and die cavity lower wall also has the curve radian the same with die cavity lower surface.
Preferably, the thickness of described die cavity lower wall is homogeneous, is about 3 ~ 30mm.
Preferably, described multiple first dividing plate and second partition intersect to install, and the cooling liquid flowing channel thus formed also is multiple.
Preferably, between described base and cover half, sealing device is provided with.
Preferably, the first described dividing plate and second partition are dismountable.
The beneficial effects of the utility model are: the thickness due to die cavity lower wall is homogeneous, can with become between mould parts to carry out uniform heat exchange, thus mould parts can be cooled to uniformly.
Accompanying drawing explanation
Fig. 1 is the injection mold schematic diagram with cooling device.
Fig. 2 is the sectional view of the A-A part of Fig. 1.
In figure: with the injection mold 1 of cooling device, dynamic model 2, cover half 3, mold base 4, die cavity 5, injection hole 6, die cavity upper surface 7, die cavity lower surface 8, heat exchange surface 9, die cavity lower wall 10, sealing device 11, cooling liquid inlet 12, cooling liquid outlet 13, first dividing plate 14, second partition 15, cooling liquid flowing channel 16.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the injection mold 1 with cooling device is made up of dynamic model 2, cover half 3 and mold base 4.When described dynamic model 2 closes with cover half 3, the middle space formed is die cavity 5, and the upper surface 7 of die cavity is positioned on dynamic model 2, and the lower surface 8 of die cavity is positioned on cover half 3.Injection hole 6 is provided with between described dynamic model 2 and cover half 3.
The bottom of cover half 3 is the structure of hollow, and die cavity lower wall 10 has certain thickness, and the upper surface of die cavity lower wall 10 is die cavity lower surfaces 8, and the lower surface of die cavity lower wall 10 is heat exchange surfaces 9.Multiple first dividing plate 14 and second partition 15 is provided with in cover half 3 bottom, first dividing plate 14 and second partition 15 intersection are arranged on described mold base 4, described mold base 4 and cover half 3 are sealed by sealing device 11, between multiple first dividing plate 14 and second partition 15, define multiple cooling liquid flowing channel 16.
Described mold base 4 is respectively equipped with coolant fluid import 12 and cooling liquid outlet 13, flows into for cooling fluid and flow out.
In actual job process, first each element of the described injection mold 1 with cooling device is installed, as shown in Figure 1.First cooling fluid input is connected with cooling liquid inlet 12, cooling fluid output is connected with cooling liquid outlet 13, feedstock transportation end is connected with injection hole 6.Open coolant recirculation pump.Make cooling fluid enter cooling liquid inlet 12 continuously, flow through in multiple cooling liquid flowing channel 16, then flowed out by cooling liquid outlet 13.
Then, material is injected in die cavity 5 via injection hole 6, die cavity 5 is filled up completely, once die cavity 5 is filled with, just stops injection moulding.
Next just can cool, in cooling procedure, cooling fluid flows through cooling liquid flowing channel 16, is taken away by the heat on mould, makes into the cooling of mould parts and solidifies.
Finally, described dynamic model 2 is removed, and mould is opened, and becomes mould parts to be pushed out, completes a work cycle.
In addition, described multiple first dividing plate 14 and second partition 15 are dismountable with mold base 4, and what be convenient to cooling liquid flowing channel 16 after long-time use is clean.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
