Abstract
The utility model discloses a nitrogen die spring. The nitrogen die spring comprises a cylinder body, guide sleeves and a plunger, wherein the guide sleeves are fastened at the upper end inside the cylinder body, the plunger can be arranged inside the guide sleeves in a vertical moving mode, a limiting boss is arranged at the lower end of the plunger, an oil chamber is arranged between the guide sleeves and the plunger, an upper sealing ring and a lower sealing ring are arranged on the guide sleeves at the upper end and the lower end of the oil chamber, a check ring is arranged between the upper end of the guide sleeve and the cylinder body, a scraper seal is arranged between the check ring and the plunger, an inflation hole is formed in the bottom of the cylinder body, and an inflation valve is arranged on the inner wall at the bottom of the cylinder body. The nitrogen die spring has the advantages of being small in size, large in elasticity, long in service life, and constant in spring force, die space can be saved due to small size, the number of springs can be reduced due to large elasticity, maintenance frequency of the die can be reduced due to long service life, and therefore total cost of the die is reduced.
Description
Technical field
The utility model relates to die springs, is specifically related to a kind of nitrogen die springs.
Background technique
Saying that die springs is popular is exactly the spring that mould is used, our die springs said is divided into metal coil spring at present, nitrogen spring, the polyurethane spring three major types, die springs is widely used in fields such as stamping die, metal crimp mold, plastic mould and other elastic movement accurate mechanical equipments, automobile, metal coil spring is simple in structure with it, advantages such as low cost of manufacture, use amount is more in accessory, but general metal coil spring use amount in mould is more, has increased the complexity of mould.
Summary of the invention
Technical problem to be solved in the utility model provides the long and constant nitrogen die springs of elastic force pressure of a kind of life-span.
The utility model is achieved through the following technical solutions: a kind of nitrogen die springs of the present utility model, described nitrogen die springs comprises cylinder body, guide sleeve and plunger, described guide sleeve is fastened on the cylinder interior upper end, described plunger can be installed in the guide sleeve up or down, described plunger lower end is provided with spacing boss, be provided with oil pocket between described guide sleeve and the plunger, be separately installed with upper sealing gasket and lower seal circle on the guide sleeve of described oil pocket top and bottom, between described guide sleeve upper end and the cylinder body back-up ring is installed, between described back-up ring and the plunger dust ring is installed, described cylinder base is provided with air-filled pore, on the described cylinder base inwall gas charging valve is installed.
Further, described gas charging valve communicates with air-filled pore.
Further, described plunger lower end is provided with slotted hole, and the slotted hole diameter is greater than the diameter of gas charging valve.
The beneficial effects of the utility model are: when using the utility model, it is little to have a volume, and elastic force is big, long and the constant characteristics of elastic force pressure of life-span, the volume I is saved die space, and elastic force can reduce number of springs greatly, life-span length can reduce the Mold repair number of times, has therefore reduced the overall cost of mould.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of a kind of nitrogen die springs of the present utility model.
Embodiment
As shown in Figure 1, a kind of nitrogen die springs of the present utility model, described nitrogen die springs comprises cylinder body 7, guide sleeve 5 and plunger 11, described guide sleeve 5 is fastened on cylinder body 7 inner upper end, described plunger 11 can be installed in the guide sleeve 5 up or down, described plunger 11 lower ends are provided with spacing boss, be provided with oil pocket 6 between described guide sleeve 5 and the plunger 11, be separately installed with upper sealing gasket 8 and lower seal circle 4 on the guide sleeve 5 of described oil pocket 6 top and bottom, between described guide sleeve 5 upper ends and the cylinder body 7 back-up ring 9 is installed, between described back-up ring 9 and the plunger 11 dust ring 10 is installed, described cylinder body 7 bottoms are provided with air-filled pore 1, on described cylinder body 7 bottom interior wall gas charging valve 2 are installed.
A kind of optimal way of the present utility model, described gas charging valve 2 communicates with air-filled pore 1.
A kind of optimal way of the present utility model, described plunger lower end is provided with slotted hole 3, and slotted hole 3 diameters are greater than the diameter of gas charging valve 2.
The beneficial effects of the utility model are: when using the utility model, it is little to have a volume, and elastic force is big, long and the constant characteristics of elastic force pressure of life-span, the volume I is saved die space, and elastic force can reduce number of springs greatly, life-span length can reduce the Mold repair number of times, has therefore reduced the overall cost of mould.
The above only is embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
