Description

Fixed form

Technical field

The utility model relates to a kind of mould accessory, is specifically related to a kind of fixed form.

Background technology

Fixed form is a kind of accessory conventional in the middle of mold injection, common mould in use, must remove die assembly to machine, generally between fixed form, places mould, then use some fixtures by fixed form and machine fixation, thereby mould can normally be worked.

The manufacture craft of mould has many kinds, every kind of requirement that technique has it should be noted, such as injection moulding, injection moulding typically uses rubber or plastics and carries out injection moulding, the general injection machine that adopts carries out injection moulding, injection machine is to utilize thermoplastic or thermosetting material to utilize mould for plastics to make the plastic products of various shapes, in the middle of the technique of injection moulding, it is an important link that thermoplastic or thermosetting material dispel the heat in the process of injection moulding, if the not good meeting of the heat dispersion of mould and fixed form causes the steel on heat conduction mould can produce thermal deformation, affect the size of mould, can be because arrived to hot problems of crack by heat problem when serious, have a strong impact on the injection moulding of mould.

Utility model content

Of the present utility modelly further be set to, be also provided with circular passage in described formwork, described circular passage connects each heat radiation chamber successively, and in heat radiation chamber, circulation has condensate liquid, offers for condensate liquid and inject and the opening of extraction in described injection-molding surfaces.

By adopting such scheme, circular passage is set in formwork, and by opening at interior injection condensate liquid, condensate liquid can be flowed between heat radiation chamber, in the process of injection moulding, in the time that the temperature being derived by fin in heat radiation chamber is inconsistent, now the condensate temperature in the higher heat radiation chamber of temperature also can raise, and the temperature of condensate liquid in the lower heat radiation chamber of temperature is lower, form the temperature difference between the two, condensate liquid now can carry out convection current by circular passage, temperature in each heat radiation chamber is consistent, make in injection moulding process, the temperature of each position of injecting hole is consistent, thermoplastic materials is consistent through the temperature flowing in mould after heat radiation, prevent from causing injecting products to occur that slight crack affects quality because the inner Yin Wendu of thermoplastic materials differs, concurrently injected condensate liquid also can be accelerated the exchange heat of fin itself, guarantee that fin can work for a long time, make fixed form can carry out long injection moulding, in the time that condensate temperature is too high, only need to carry out the supply of condensate liquid and change by opening, the working time of fixed form is guaranteed.

Of the present utility modelly further be set to the round table-like setting of hollow out in the middle of described boss is.

By adopting such scheme, boss is arranged to round table-like, can overcome original shortcoming that need connect with limit muscle four brail boss, simplify production, save material, strengthen the rigidity of a plate, thereby improved the quality of products, reduce production costs.

Of the present utility modelly further be set to, on described installed surface, be provided with symmetrical some installing holes.

By adopting such scheme, symmetrical some installing holes are set on installed surface, make fixed form to carry out the mould that all size differs by installing hole and load, allow fixed form can applicable scope become more extensive, be adapted to the loading of injection mold.

Of the present utility modelly further be set to, described fin is made up of aluminium alloy.

By adopting such scheme, because aluminium alloy has quite good heat dispersion, the simultaneously processability of aluminium alloy and surface treatment all suitable easily and simply too much, and suitable low of its cost, although the heat conductivility of aluminium alloy is slightly inferior to copper, but aluminium alloy occupies sizable advantage in price, the manufacturing cost of fixed form is reduced greatly.

Of the present utility modelly further be set to, described condensate liquid is water.

By adopting such scheme, the specific heat capacity of water itself is larger, be suitable for various heat exchanges, and can carry out for a long time work, water is after carrying out the absorption of heat simultaneously, can also, by again condensate liquid being injected in the middle of meeting fixed form after the heat recycling in the middle of the condensate liquid of extracting out, utilization efficiency of heat energy be improved greatly, indirectly reduce production cost.
