Abstract
The utility model discloses an injection oil return pipe for a die casting machine, relating to field of mechanical equipment. The injection oil return pipe comprises an oil return pipe body, wherein the oil return pipe body is a seamless steel pipe; a boss is arranged on the left end joint of the oil return pipe body, and is provided with a through hole; a bolt passes through the through hole; and the injection oil return pipe is connected with an injection oil return pipe supporting seat through an external bolt. The injection oil return oil pipe has a simple structure and is low in manufacturing cost; and boss connection is adopted instead of an original connection way of processing a screw thread on the outer wall of the oil return pipe, and the boss is arranged additionally, so that the strength of the oil return pipe is not weakened but is increased, and thereby, the service life of the oil return pipe is prolonged.
Description
Technical field:
The utility model relates to the plant equipment field, relates in particular to a kind of die casting machine injection oil return pipe.
Background technology:
Die casting machine is exactly under pressure molten metal bath injection cooling forming in the mould, obtains a series of industrial foundry machinery of solid metal foundry goods after the die sinking, is used for the die casting font at first.Along with science and technology and industrial progress, especially along with industrial expansions such as automobile, motorcycle and household electrical appliance, from energy-conservation, many aspects such as saving raw material etc., die-casting technique has obtained to develop extremely rapidly again.
Die casting machine divides hot pressing constant pressure casting machine and cold pressing chamber die casting machine two big classes.The cold pressing chamber die casting machine presses cell structure and arrangement to divide horizontal, vertical two kinds of forms again by it.Hot pressing constant pressure casting machine is the same with the clamping of cold pressing chamber die casting machine, and its difference is injection, cast mechanism difference.The pressure chamber of hot pressing constant pressure casting machine and smelting furnace closely are linked to be an integral body, and the pressure chamber of cold pressing chamber die casting machine is what to separate with smelting furnace.
Along with science and technology and industrial progress, especially along with industrial expansions such as automobile, motorcycle and household electrical appliance, from energy-conservation, saving raw material aspects, die-casting technique has obtained to develop extremely rapidly again.Die casting is produced and not only in nonferrous alloy casting, is occupied an leading position, and has become an important component part of modern industry.In recent years; Some countries are owing to rely on technological progress to impel foundry goods thin-walled property, lightweight, thereby cause in the past changing into the level of the technological progress important evidence as a national casting level of measurement with the idea of a national foundry engieering development level of casting output evaluation.
In the prior art, the injection oil returning pipe joint place of die casting machine is shaped on external screw thread, is connected with injection oil return pipe bearing through screw thread; In injection process; The injection oil return pipe bears radial pressure, and threading can reduce the intensity of injection oil return pipe on the injection oil return pipe, and service life is short.
The utility model content:
The utility model technical problem to be solved is to provide a kind of not die casting machine injection oil return pipe of threading on tube wall.
The utility model technical problem to be solved adopts following technical scheme to realize,
A kind of die casting machine injection oil return pipe comprises the oil return pipe body, it is characterized in that: said oil return pipe body left end joint is provided with boss, and boss is provided with through hole.
Said oil return pipe body is a seamless steel pipe.
The injection oil return pipe is connected through the bolt that adds with injection oil return pipe bearing.
The utility model is simple in structure, low cost of manufacture, change original on the oil return pipe outer wall connected mode of machining screw set up the intensity that boss not only can not weaken oil return pipe for connecting through boss, intensity is increased, thereby prolong the service life of oil return pipe.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1, a kind of die casting machine injection oil return pipe comprises oil return pipe body 3, and oil return pipe body 3 is a seamless steel pipe, and oil return pipe body 3 left end joints are provided with boss 1, and boss 1 is provided with through hole 2, passes bolt in the through hole 2.
The injection oil return pipe is connected through the bolt that adds with injection oil return pipe bearing.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. a die casting machine injection oil return pipe comprises the oil return pipe body, it is characterized in that: said oil return pipe body left end joint is provided with boss, and boss is provided with through hole.
