Description
Technical Field
The utility model relates to a vacuum die-casting technical field especially relates to a vacuum exhaust valve of high life.
Background
The die casting die mechanical vacuum valve carries out air entraining and air exhaust through a runner of a movable die and a fixed die, and the existing mechanical vacuum valve has the following defects:
1. the existing mechanical vacuum valve is easy to be blocked and has lower use efficiency;
2. the existing mechanical vacuum valve is not easy to disassemble after aluminum is leaked;
3. the prior vacuum valve insert pin is easy to damage;
4. the stability of the existing mechanical vacuum valve is poor.
Therefore, a novel vacuum exhaust valve needs to be designed for use
SUMMERY OF THE UTILITY MODEL
The utility model discloses a mesh equipment provides a vacuum exhaust valve of high life to overcome the above-mentioned not enough that prior art exists at present.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a vacuum exhaust valve of high life, includes movable mould and cover half, sets up the vacuum exhaust valve on movable mould and cover half, its characterized in that: vacuum exhaust valve inlays the needle including setting up movable mould valve body, vacuum valve cover half on the movable mould vacuum valve cover half inlays needle position department and is provided with the recess the oral area that the needle was inlayed to the vacuum valve cover half is provided with the chamfer.
Preferably, a fixed die top core is arranged in the fixed die.
Preferably, a vacuum machine is connected to the movable die.
The utility model has the advantages that: the groove is additionally arranged at the position of the insert pin of the fixed die of the vacuum valve, so that the insert pin is prevented from deforming and being stuck; the vacuum valve inserted needle mouth part is chamfered, so that the inserted needle mouth part is prevented from being crushed and deformed; the replacement frequency of the insert pin due to deformation and collapse is reduced, and the production efficiency is improved; the sealing surface aluminum leakage and air leakage phenomena in the use process of the mechanical vacuum valve are reduced, the production efficiency is improved, the use efficiency of the mechanical vacuum valve is improved, the reject ratio and the labor cost of products are reduced, and the stability of the overall quality of the products is improved.
Drawings
FIG. 1 is a schematic structural view of a long-life vacuum exhaust valve according to the present invention;
FIG. 2 is a cross-sectional view of a long life vacuum exhaust valve of the present invention;
in the figure: 1. a movable mold valve body; 2. and (5) fixing a mould and inlaying a needle in the vacuum valve.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1 and 2, the present embodiment is a vacuum exhaust valve with a long service life, including a movable mold and a fixed mold, and a vacuum exhaust valve disposed on the movable mold and the fixed mold, and is characterized in that: vacuum exhaust valve is including setting up movable mould valve body 1, vacuum valve cover half on the movable mould inlay needle 2 the vacuum valve cover half inlays 2 position departments of needle and is provided with the recess the oral area that needle 2 was inlayed to the vacuum valve cover half is provided with the chamfer.
And a fixed die top core is arranged in the fixed die. And ejecting a product through the fixed die ejection core to enable the product to be separated from the fixed die valve body and demoulded to the movable die valve body side.
And the movable die is connected with a vacuum machine. Vacuum was drawn through the vacuum machine.
In the implementation of the embodiment, when the movable mold and the fixed mold are assembled, the movable mold valve body presses the fixed mold valve body insert pin; after the die is closed, a vacuum machine extracts vacuum; after vacuumizing is finished, die casting is started on the die, the aluminum liquid flows to provide pressure, the middle valve core is compressed, and the air exhaust valve core is closed until die casting is finished;
after the mold is opened, the movable mold valve body and the fixed mold valve body are separated, the fixed mold valve core ejects a product to be separated from the fixed mold valve body and demoulded to the movable mold valve body side, and after the mold is opened in place, the product is taken out and the mold is subjected to actions of whistle blowing, cooling, cleaning and the like.
The utility model has the advantages that: the groove is additionally arranged at the position of the insert pin of the fixed die of the vacuum valve, so that the insert pin is prevented from deforming and being stuck; the vacuum valve inserted needle mouth part is chamfered, so that the inserted needle mouth part is prevented from being crushed and deformed; the replacement frequency of the insert pin due to deformation and collapse is reduced, and the production efficiency is improved; the sealing surface aluminum leakage and air leakage phenomena in the use process of the mechanical vacuum valve are reduced, the production efficiency is improved, the use efficiency of the mechanical vacuum valve is improved, the reject ratio and the labor cost of products are reduced, and the stability of the overall quality of the products is improved.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
