Description
Technical field
The utility model belongs to the injection mold technical field, particularly relates to a kind of injection mold heat-exchange tube cooling body.
Background technology
Existing method is that cooling tube or water proof sheet are installed in position that mould need cool off, allows cooling water play up and down in water pipe by the water route circulation, and the heat of mould side wall is taken away.As Fig. 1 to Fig. 3.But this type of mechanism size is bigger, and heat exchange effect is not obvious, needs to adopt new mode, promotes die quality.
Adopt existing organization plan, the aperture size of cooling tube and the required installation of water proof sheet is bigger, in tiny mould structure, can't realize, cooling water pipe and water proof sheet may cause the stagnant water phenomenon, the mould part can not be cooled off, simultaneously after long-time the use, the hole, water route can because of get rusty, reason such as incrustation scale makes current reduce to cause cooling effect decline.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of injection mold heat-exchange tube cooling body, reduce the cooling water channel placement space, make the tiny mould structure of cooling become possibility, further simplified global design simultaneously, reduce the mould development time, saved cost.The cooling effect of this structure is extremely strong, and heat exchange is even, can improve whole cooling effect, has reduced circulation timei, and this material can not get rusty, and is convenient to maintenance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of injection mold heat-exchange tube cooling body is provided, comprise core, template and housing, it is die joint above the described core, described die joint contacts with product, below the described core installing hole is arranged, heat-exchange tube is installed, described heat-exchange tube into strips, described heat-exchange tube upper end is evaporimeter, the lower end is condenser, described core connects template, corresponding core installing hole place has through hole on the described template, the through hole that described heat-exchange tube passes template enters U-lag in the template, described U-lag is communicated with extraneous cooling water by the pipeline that forms between template and the housing, described housing is installed in the template bottom, and there is opening at corresponding U-lag place on the described housing, is connected with conical plug with removably on the described opening.
Described heat-exchange tube top is packed into below the core in the installing hole, the bottom has end cap, and described heat-exchange tube comprises that vacuum sealing tube, a lining is equipped with wick and nontoxic hydraulic fluid, innerly is heat exchange chamber.
Seal by sealing ring between described core and the template.
Described vacuum sealing tube is made with copper product.
Beneficial effect
Advantage of the present utility model is, can place cooling water channel easily in leptosomatic mould structure, further simplifies global design.Good cooling results, heat radiation evenly reduce circulation timei, promote the water route turbulent flow, can not get rusty, and have reduced a large amount of maintenances.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Shown in Fig. 4 to 5, a kind of injection mold heat-exchange tube cooling body, comprise core 1, template 2 and housing 3, be die joint above the described core 1, described die joint contacts with product 12, below the described core 1 installing hole is arranged, heat-exchange tube 4 is installed, described heat-exchange tube 4 into strips, described heat-exchange tube 4 upper ends are evaporimeter, the lower end is condenser, described core 1 connects template 2, corresponding core 1 installing hole place has through hole on the described template 2, the through hole that described heat-exchange tube 4 passes template 2 enters U-lag 5 in the template 2, and described U-lag 5 is communicated with extraneous cooling water by the pipeline that forms between template 2 and the housing 3, and described housing 3 is installed in template 2 bottoms, there is opening at corresponding U-lag 5 places on the described housing 3, are connected with conical plug 6 with removably on the described opening.
Described heat-exchange tube 4 tops are packed into below the core 1 in the installing hole, the bottom has end cap 8, and described heat-exchange tube 4 comprises that vacuum sealing tube, a lining is equipped with wick 9 and nontoxic hydraulic fluid 11, innerly is heat exchange chamber 10.
Seal by sealing ring 7 between described core 1 and the template 2.
Described vacuum sealing tube is made with copper product.
Structural principle: heat-exchange tube 4 is made up of a vacuum seal copper tube, and a wick and nontoxic hydraulic fluid are housed in the copper tube.Different functions is fulfiled at the two ends of heat-exchange tube 4, and an end is evaporimeter, and the other end is condenser.
Heat concentrates on evaporimeter one end in the U-shaped groove in the injection moulding process, and evaporimeter evaporates hydraulic fluid.Steam passes heat-radiating rod then and arrives condenser one end.At condenser one end, steam is condensed into liquid, discharges latent heat in this process.Finish this circulation, the liquid of process condensation moves ahead along wick, by the capillary hygroscopic effect, turns back to evaporator section.
This process repeats continuously itself, carries out conveying heat repeatedly, and heat-radiating rod should suitably extend into water piping.The ideal length that heat-radiating rod contacts with cooling fluid should be 25% of length that heat-radiating rod contacts with thermal source at least, and the heat that accumulates in condenser one end so just can be taken away by cooling water.
Adopt heat-exchange tube as the cooling medium of cooling water channel, can reduce the cooling water channel placement space, make the tiny mould structure of cooling become possibility, further simplified global design simultaneously, reduced the mould development time, saved cost.The cooling effect of this structure is extremely strong, and heat exchange is even, can improve whole cooling effect, has reduced circulation timei, and this material can not get rusty, and is convenient to maintenance.
