Abstract
The utility model provides a floating piston for an energy accumulator of an injection system in a die-casting machine. The floating piston comprises a floating piston and a seal groove and further comprises a groove. The seal groove is formed outside the floating piston, grooves are formed in the floating piston, and the floating piston is a die-casting aluminum part. The grooves are formed in the upper face and the lower face of the floating piston respectively. The floating piston for the energy accumulator of the injection system in the die-casting machine has the advantages that due to the fact that by means of the technical scheme, the floating piston made of die-casting aluminum is adopted, the weight of the floating piston of the same volume is light, a cut surface is firmer without seams through the die-casting process, gas and oil are separated, the floating piston is more conveniently operated, product quality is improved, uniformity of products is maintained, and the floating piston has the advantages of being simple in structure, convenient to maintain, low in processing cost, high in production efficiency and the like.
Description
Technical field
The utility model belongs to mechanical equipment technical field, especially relates to the floating piston that the accumulator of injection system in a kind of die casting machine is used.
Background technique
In existing technology, what affect die casting machine is mainly injection system, and die casting machine is core engine, and accumulator is for affecting the key component of moment injection.And the floating piston of accumulator commonly used the inside is spheroidal graphite cast iron, its benefit is to realize quick injection when running up, and is exactly in fact the speed of floating piston supercharging, and the main purpose of spheroidal graphite cast iron prevents from scratching the accumulator inwall exactly, in generation, lets out.In the floating piston of spheroidal graphite cast iron, the eye of wind is arranged, while running up, heating is expanded and is formed oil film, thereby plays protection.
And the external general cast copper that adopts.By our long-time great many of experiments, reach a conclusion, what really affect injection system is floating piston weight, and during the larger motion of its weight, the kinetic energy of moment is larger, and the impulse force while stopping is larger.Thereby the pressure surge that affects injection system strengthens.The casting defect impact of the floating piston of spheroidal graphite cast iron is larger.And have trachoma may make gas and oil phase lead to the man-hour that adds of the floating piston of spheroidal graphite cast iron being carried out to weight reduction in spheroidal graphite cast iron, the injection effect is bad, and the homogeneity of product of generation is poor, can not guarantee to produce the quality of product.
Summary of the invention
Problem to be solved in the utility model is to provide the floating piston that the accumulator of injection system in a kind of die casting machine is used, and the die casting machine that especially is applicable to producing typical products in mass production uses.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the floating piston that in a kind of die casting machine, the accumulator of injection system is used, comprise floating piston, seal groove, also comprise groove, described floating piston is provided with seal groove outward, described floating piston is provided with groove, and described floating piston is the die casting aluminum component.
Further, described floating piston above be provided with groove.
Further, described floating piston below be provided with groove.
Further, described floating piston top and below be equipped with groove.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, adopt the floating piston of die casting aluminium, the weight of its same volume is lighter, but also the technique by die casting does not have a gap by cutting surfaces is firmer, isolation gas and oil, more convenient to operate, improved quality of product, product is kept consistency; Have simple in structurely, easy to maintenance, processing cost is low, the manufacturing efficiency advantages of higher.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing floating piston;
Fig. 2 is structural representation of the present utility model.
In figure:
1, floating piston 2, seal groove 3, groove
Embodiment
As shown in Figure 2, the floating piston that in a kind of die casting machine of the utility model, the accumulator of injection system is used, comprise floating piston 1, seal groove 2, also comprise groove 3, described floating piston 1 is outer is provided with seal groove 2, and described floating piston 1 is provided with groove 3, and described floating piston 1 is the die casting aluminum component.Be provided with groove 3 above described floating piston 1.Be provided with groove 3 below described floating piston 1.Described floating piston 1 top and below be equipped with groove 3.
The working procedure of this example: the floating piston of die casting aluminium 1 is inserted in accumulator, drive the injection system motion, make the die casting machine running produce product.On the floating piston 1 of die casting aluminium and below be provided with groove 3, its weight is reduced.When the floating piston 1 of die casting aluminium turns round, the less quality that guarantees product of fluctuation of moment, reduce its deviation, strengthened the conformity of product.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
