Abstract
The utility model discloses the injection molds with cooling pipe, including injection hole, upper die holder, lower die holder, cavity plate and type core；Bending is equipped with circulation line in cavity plate；Circulation line one end is equipped with water inlet, and the other end is equipped with water outlet；Circulation line upper end is equipped with aluminum heat conducting plate；Aluminum heat conducting plate upper surface is connected to type core lower end；Circulation line inner wall is equipped with multiple waterstops；Each waterstop is equipped with through-hole along water (flow) direction, and the aperture of through-hole is greater than or equal to the length of waterstop.The beneficial effects of the utility model are: by the way that circulation line is arranged in cavity plate, and circulation line is abutted with aluminum heat conducting plate, so that the temperature of type core and circulation line quickly can mutually conduct, cooling or heating are rapidly and steady, and due to being equipped with waterstop in circulation line, so that the cold water or flow rate of hot water in circulation line reduce, so that constant temperature time is longer, and since water easily rolls so that it is wider with circulation line contact surface, heat conduction efficiency is more preferable.
Description
Technical field
The utility model relates to a kind of injection mold more particularly to a kind of injection molds with cooling pipe.
Background technique
Mold is a kind of tool for producing plastic products.It is made of a few group part parts, has shaping mould in this combination
Chamber.When injection molding, clamping mould is on injection molding machine, and it is intracavitary that molten plastic is injected into pattern, and in intracavitary cooling and shaping, then on
Lower die separates, and product is left mold from die cavity ejection via ejection system, last mold recloses to be molded next time, whole
A injection moulding process is that circulation carries out.Since the difference of injecting products requires, the requirement to mold is also different, and existing injection molding
The mode that mold generallys use water circulation is cooled down, but water pipe is only arranged in existing mode in mold, not to water pipe into
Row special designing causes cooling effect undesirable, if desired improves cooling effect, and universal design is to improve path in water pipe mould,
That is bending setting water pipe, so that the water pipe in mold is longer, but this mode will lead to mold compression strength difference or increase mold
Volume；And there are also some molds by the way of adding refrigeration source or reducing water cooling temperature, this type of cooling higher cost, and
It is impracticable.
Utility model content
The purpose of this utility model seeks to overcome above-mentioned the deficiencies in the prior art, provides a kind of note with cooling pipe
Mould, with cooling efficiency height, at low cost, the characteristics of not increasing mould volume.
To achieve the above object, designed by the utility model with cooling pipe injection mold, including injection hole, on
Die holder, lower die holder, the cavity plate between the upper die holder and lower die holder and the type core intracavitary set on the type of the cavity plate；It is described
Bending is equipped with circulation line in cavity plate；Described circulation line one end is equipped with the water inlet for injecting cold/hot water, and the other end is equipped with
For the water outlet of cold/hot water to be discharged, and the water inlet and the water outlet are set to the die outside wall；The circulation pipe
Road end is adherent to be equipped with aluminum heat conducting plate；The aluminum heat conducting plate upper surface is connected to type core lower end；The circulation line inner wall
Equipped with multiple waterstops, the length of the waterstop is greater than the tube body radius of the circulation line；Each waterstop is along water
It flows direction and is equipped with through-hole, the aperture of the through-hole is greater than or equal to the length of the waterstop.
Further, the waterstop is obliquely installed in the circulation line inner wall, and waterstop at least one end with follow
Ring pipeline inner wall keeps gap.
Preferably, the tilt angle of the waterstop is less than or equal to 45 degree.
Still further, the water inlet and the water outlet are respectively equipped with valve.
Preferably, the valve is solenoid valve.
The beneficial effects of the utility model are: by the way that circulation line is arranged in cavity plate, and circulation line is supported with aluminum heat conducting plate
Connect so that the temperature of type core and circulation line quickly can mutually conduct, cool down or heat up it is rapidly and steady, and due to circulation line
It is interior to be equipped with waterstop so that the chilled water flow velocity in circulation line reduces so that cooling time is longer, and easily rolled due to water so that
It is wider with circulation line contact surface, and cooling effect is more preferable；In addition, due to the design of through-hole, so that the water in circulation line is not
Excessively blocking flow velocity can be influenced, so that heat can quickly be taken away from through-hole by water flow, raising water flow is same with mold time of contact
When also do not reduce heat dissipation effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the injection mold that the utility model has cooling pipe.
Fig. 2 is the partial enlargement diagram of Fig. 1.
1. injection hole in figure；2. upper die holder；3. lower die holder；4. cavity plate；5. type chamber；6. type core；7. circulation line；8. entering water
Mouthful；9. water outlet；10. aluminum heat conducting plate；11. waterstop；12. through-hole.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The injection mold for having cooling pipe as shown in Figure 1, 2, including injection hole, upper die holder, lower die holder, be set to upper die holder
Cavity plate and the type core intracavitary set on the type of cavity plate between lower die holder；Bending is equipped with circulation line in cavity plate；Circulation line one
End is equipped with water inlet for injecting cold/hot water, and the other end is equipped with the water outlet for cold/hot water to be discharged, and water inlet with go out
The mouth of a river is set to die outside wall；Circulation line upper end is adherent to be equipped with aluminum heat conducting plate；Aluminum heat conducting plate upper surface is connected to type core lower end；
Circulation line inner wall is equipped with multiple waterstops, and the length of waterstop is greater than the tube body radius of circulation line；Each waterstop is along water
It flows direction and is equipped with through-hole, the aperture of through-hole is greater than or equal to the length of waterstop.
Between waterstop is obliquely installed in circulation line inner wall, and waterstop at least one end and circulation line inner wall are kept
Gap.The tilt angle of waterstop is less than or equal to 45 degree.Water inlet and water outlet are respectively equipped with valve (preferably solenoid valve).
Certainly, also water tank and the heating/refrigerating device being used cooperatively with the injection mold of the utility model, heating device is in water tank
Water heating, can thus when being flowed in circulation line so that enter the water of circulation line with certain temperature by water inlet
Transfer heat to aluminum heat conducting plate.And when cooling is needed, can freeze to water tank, or directly by the water in water tank pass through into
Circulation line is injected at the mouth of a river.Due to the effect of waterstop, can reach very well without being lengthened to the circulation line in mold
Constant temperature effect.
