Description
Technical field
The invention belongs to injection-moulding device technical field, especially a kind of improved injection mold.
Background technology
Mould is essential instrument in injection moulding, and injection moulding is that the plastic material that will heat state is noted from the injection hole of mould
Enter in mould in the closed die cavity of shape with needed for, after after plastic material cooling and solidifying, open the plastic top that mould will solidify
Go out, the processing method to obtain shaped article.The processing method of injection moulding has shaping low cost, short molding cycle, shaping
Process is simple, it is easy to the features such as forming shape complicated plastic, therefore application in moulding process is extremely wide.
At present, the form of injection mold is also varied, and mould mostly includes dynamic model and cover half, due to mould dynamic model with it is fixed
Mould is during use, it is necessary to be fitted regularly and separated, when dynamic model is fitted with cover half, the two is often
The two is carried out into setting of fitting by larger active force, the dynamic model and cover half can greatly wear and tear two due to for a long time using
The binding face of person, highly shortened the mold use life-span, improve the production cost of enterprise；Meanwhile, dynamic model and cover half
Binding face be mostly directly contact, it is impossible to the sealing of the two is completely secured, it is impossible to ensure the quality of obtained product, to making
With bringing inconvenience.
In addition, being provided with heating wire on the outside of the injection hole of existing part injection mould, concave shaped cavity, electricity also is provided with the inside of projection
Heated filament, such as injection mold disclosed in patent publication us CN204109240U, due to also being provided with electric heating on the outside of concave shaped cavity
Silk, this kind of setting of structure so that the time that the plastic material of the hot melt state being injected into concave shaped cavity is cooled and solidified in concave shaped cavity
Further extend, reduce operating efficiency, meanwhile, if the plastic material of the hot melt state in concave shaped cavity can not be in a short time
If cooling and solidifying shaping, the quality of obtained product can be influenceed, cause the waste of substandard product, improve enterprise
Production cost.
By retrieval, such as the next chapter patent publication us related to present patent application are found：
A kind of a kind of improved injection mold (CN204109240U), there is provided the improved injection mold of long service life, including
Cover half, injection hole, intermediate mass, dynamic model etc., the left side of the cover half is middle piece, and injection hole is offered on the cover half, described
The rear end of injection hole is provided with compensation pad, and the intermediate mass is provided with concave shaped cavity, and the upper end of the intermediate mass is provided with non-return valve, described
Non-return valve is connected with concave shaped cavity, and the inside of the intermediate mass is provided with exhaust outlet, and the exhaust outlet is connected with the bottom of concave shaped cavity, institute
The left side of intermediate mass is stated for dynamic model, heating wire is provided with the outside of the injection hole, concave shaped cavity, electric heating is provided with the inside of the projection
Silk, fixed mount is provided with the left of the dynamic model.The utility model increases non-return valve in the upper end of intermediate mass, it is ensured that in die cavity
Pressure is constant, not only greatly reduces infringement of the high pressure in die cavity to die cavity, extends the service life of injection mold, also protects
The quality of injecting products is demonstrate,proved.
By contrast, there is the difference of essence with above-mentioned patent publication us in present patent application.
The content of the invention
