Description
Technical field
The present invention relates to a kind of injection mold, more particularly to a kind of Intelligent temperature control type thin wall type injection mold.
Background technology
Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches, refers specifically to melt heated
The material of change injects die cavity by high pressure, after cooling and solidifying, obtains formed products.Injection mold is a kind of work for producing plasthetics
Tool；Also it is to confer to the instrument of plasthetics complete structure and accurate dimension.It is larger for picture automobile door plate, headstock cover plate homalographic
Thin wall type plastic, when being molded, there is problems with traditional moulds：1st, due to the area of thin wall type plastic is larger and thin and thick
It is relatively thin, it is molded using ordinary temperature, easily due to heated uneven, causes thin wall type plastic locally to deform or lack
Material, and if using too high temperature, plastic degradation cracking is easily caused again, influence the quality of plastics；2nd, thin wall type plastic unlike
Conventional plastic can bear larger because of the residual stress that heat transfer is uneven and produces like that, therefore traditional water channel cooling is unsuitable
Thin wall type plastic, while if using traditional water channel cooling, the volume of mould, the manufacture body of mould can be greatly increased
Greatly improve.Therefore it is the dimensional stability of guarantee plastic, it is just necessary shrinking with warpage control within the acceptable range
Strengthen the cooling of mould, it is ensured that cooling is balanced.
The content of the invention
Goal of the invention：The present invention solves above mentioned problem, and there is provided a kind of Intelligent temperature control type thin wall type injection mold.
Technical scheme：A kind of Intelligent temperature control type thin wall type injection mold, including
Die ontology, the die ontology is included after the fixed half and moving half cooperated, the fixed half and moving half matched moulds,
Formed between the dynamic model and cover half and hot flow path is provided with injection die cavities, the die ontology, the hot flow path and the note
Plastotype chamber is connected；
Ceramic heat block, the fixed half and moving half is internally provided with cavity, the ceramic heat block for it is multiple and anyhow into
Array arrangement is installed in the cavity, and the spacing of the adjacent ceramic heat block is 0.5~5cm；
Temperature probe, the temperature probe is identical with the ceramic heat number of blocks, is installed on the interior of the injection die cavities
On wall, and it is corresponding with the ceramic heat block position；
Temperature-controlled cabinet, the temperature-controlled cabinet is connected with the temperature probe, receives the temperature of the temperature probe detection
Degrees of data, the temperature-controlled cabinet is connected with the ceramic heat block, controls the heating-up temperature of the ceramic heat block；
Air channel, is provided with multiple air ports on the fixed half and moving half, and the air port is connected with the cavity, the ceramics
Gap forms air channel with the air port between heat block.
As a preferred embodiment of the present invention, PLC is installed on the temperature-controlled cabinet.
As a preferred embodiment of the present invention, the uniform wall thickness between the cavity and the injection die cavities is 1~
3cm。
As a preferred embodiment of the present invention, the ceramic heat block is cuboid or cylinder.
As a preferred embodiment of the present invention, the spacing of the adjacent ceramic heat block is 0.5~2cm.
As a preferred embodiment of the present invention, the air port is arranged in pairs, respectively positioned at the cover half or the dynamic model
Both sides.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention, and the present invention can be visited by temperature probe
Survey injection die cavities in temperature, then temperature probe the temperature data detected is transferred to temperature-controlled cabinet, temperature-controlled cabinet
The heating-up temperature of ceramic heat block is controlled, mold injection die cavity is heated evenly；During cooling, injection mold is carried out by air channel
Cooling, can prevent from, because of the residual stress that heat transfer is uneven and produces, making injection mold uniformly cool down, fast cooling, while with using
Water channel cooling is compared, and greatly reduces the manufacturing cost of mould；And can also be by air channel and ceramic heat in cooling procedure
Agllutination is closed, and for cooling down too fast position, can suitably be heated.The present invention is rational in infrastructure, is particularly suitable for use in thin-walled shape
The injection molding of part, injection moulding process homogeneous heating, is uniformly cooled down during cooling, and cooling efficiency is fast, and die quality is light, is manufactured into
This is low, and controllability is good.
