The utility model discloses a design in cooling water route, the shrink orientation of utilizing the temperature difference to define the product has compensated product internal strain deviation, has improved the product percent of pass.
Description
【Technical field】
This utility model belongs to Design of Dies technical field, and more particularly to a kind of cooling system improves the mould of deformation of products
Tool.
【Background technology】
In numerous structures of injection mold, cooling system, as one of key technology in injection mold, is controlling mould
Tool temperature aspect plays vital effect.Cooling system can be by the major part of release during molten plastic solidified forming
Heat is taken away, quick shaping product can be reached, buckling deformation that uniformly cooling, prevention residual stress and ununiform shrinkage cause,
Shorten the purpose of forming period.
In prior art, the setting of the cooling system in most of mould, all carry out around product outer peripheral contour
Arrangement cooling water pipe, for the product with thin-wall case structure, especially relatively has distance and wants between two thin-wall cases
Ask or the perpendicularity of thin-walled has a necessarily required product, its product both sides of producing of the cooling water pipe of the method setting are thin
Wall housing is deformed inward as 1.0～1.2mm it is impossible to reach customer requirement.
Therefore, it is necessary to provide a kind of new cooling system to improve the mould of deformation of products to solve the above problems.
【Utility model content】
Main purpose of the present utility model is the mould providing a kind of cooling system to improve deformation of products, by cooling water
The design on road, defines the shrinkage direction of product using temperature difference, compensate for deformation deviation in product, improves product qualified
Rate.
This utility model is achieved through the following technical solutions above-mentioned purpose：A kind of cooling system improves the mould of deformation of products
Tool, it includes upper cores and lower die, and for molded housing, described lower die is internally provided with cooling system and up/down perforation
Port, contain the core forming described housing with described port inwall, described upper cores surface in described port, described cold
If but system include around described core outer peripheral contour setting cooling water pipe and be arranged on dry and cold within described core
But well, the cooling water temperature in described cooling water pipe is less than the temperature of cooling water in described cooling well.
Further, described housing include the first plate face, perpendicular to described first plate face and opposing parallel setting
Two plate faces and the 3rd plate face, described first plate face, described second plate face and described 3rd plate face are collectively forming an enclosing region.
Further, described core is located in described enclosing region.
Further, described cooling water pipe is interconnected.
Further, described cooling well is internally provided with the shaping piece being isolated into two connected components.
Further, described cooling water pipe is separately positioned with described cooling well.
Compared with prior art, the beneficial effect of the mould that a kind of cooling system of this utility model improves deformation of products exists
In：Be located at the core in product center region by setting, and the insert perimeter cooling water pipe separate with internal setting with
Cooling well, and be passed through in cooling water pipe with cooling well and there is the coolant of certain temperature difference so that after product injection mo(u)lding,
Product side wall both sides produce certain temperature difference, thus affecting the shrinkage factor of product so that product size is compensated, and make
Product is shunk according to the direction setting；Improve conforming product rate.

【Specific embodiment】
Embodiment：
Refer to Fig. 1-Fig. 4, the present embodiment improves the mould 100 of deformation of products for cooling system, including upper cores 1 with
Die 2.For molded housing 101, housing 101 includes the first plate face 1011, perpendicular to the first plate face 1011 and opposing parallel
Second plate face 1012 of setting and the 3rd plate face 1013.First plate face 1011, the second plate face 1012 are common with the 3rd plate face 1013
Form an enclosing region 1014.
Lower die 2 is internally provided with the port (in figure does not indicate) of up/down perforation, contain in port with port inwall, on
Die 2 surface forms the core 3 of housing 101.Core 3 is located in enclosing region 1014.
Lower die 2 is internally provided with cooling system 4.Cooling system 4 include around core 3 outer peripheral contour setting and phase
Intercommunicated cooling water pipe 41 and be arranged on four cooling wells 42 within core 3.Cooling well 42 be internally provided with by
It is isolated into the shaping piece 43 of two connected components.Each cooling well 42 is made to form a mobility by shaping piece 43
Cooling duct, constantly the heat in core 3 is taken away.
Cooling water pipe 41 is separately positioned with cooling well 42.Cooling water temperature in cooling water pipe 41 is less than cooling well 42
The temperature of interior cooling water.In the present embodiment, the cooling water temperature in cooling water pipe 41 is 90 DEG C, cooling water in cooling well 42
Temperature is 0 DEG C.
The present embodiment cooling system improves having the beneficial effects that of the mould 100 of deformation of products：Product is located at by setting
The core of central area, and in the insert perimeter cooling water pipe separate with internal setting and cooling well, and in cooling water
It is passed through the coolant with certain temperature difference so that after product injection mo(u)lding, product side wall both sides produce one in pipe and cooling well
Fixed temperature difference, thus affecting the shrinkage factor of product so that product size is compensated, and makes product according to the direction setting
Shunk；Improve conforming product rate.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality
New protection domain.
