Description
Technical Field
The utility model relates to an injection chamber field technique especially indicates an injection chamber structure.
Background
The injection chamber refers to a circular cylinder body containing molten metal in a die casting machine, and the molten metal is pressed by the injection chamber and injected into a cavity through a gate, which is an essential key part in the design of a die casting mold.
When the pouring temperature of injected molten metal of the existing injection chamber is 650-720 ℃, and the filling rate of the injection chamber is generally ensured to be 40-70%, 30-60% of the positions are not in direct contact, the parts are filled with gas, and if the gas is not extracted, the gas enters a die cavity along with the molten metal, so that various defects such as bubbles and the like appear on a casting, and the quality of the casting is reduced. Accordingly, there is a need for improvements to current shot chambers.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention is directed to the defects existing in the prior art, and the main objective of the present invention is to provide an injection chamber structure, which can greatly improve the quality of castings.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an injection chamber structure comprises a main body part and a mounting part which are integrally formed and connected sequentially from front to back; the main body part is internally provided with an accommodating cavity with a forward opening, the top surface of the main body part is provided with an air suction opening and a discharge opening which are communicated with the accommodating cavity, an end pipe is arranged in the front end of the main body part, a branch pipe is arranged in the rear end of the main body part, the branch pipe and the end pipe are communicated through a connecting pipe, and the connecting pipe is positioned in the main body part.
Preferably, the branch pipe is a plurality of branch pipes, and the plurality of branch pipes are communicated in sequence and are uniformly distributed on the periphery of the main body part in a semi-annular shape.
Preferably, the suction opening is located at the rear side of the feed opening.
Preferably, the joint between the main body part and the mounting part is radially enlarged to extend out of a limit ring.
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:
through being provided with the extraction opening, before the injection, the accessible extraction opening is bled the gas in the holding chamber, avoids gas to get into the die cavity of mould along with the molten metal in to avoid various flaws such as bubble to appear in the foundry goods, effectively promoted the shaping quality of foundry goods.
To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Drawings
FIG. 1 is a perspective view of a preferred embodiment of the present invention;
fig. 2 is a front view of the preferred embodiment of the present invention.
The attached drawings indicate the following:
10. main body part 11 and accommodating cavity
12. Air extraction opening 13 and feed opening
14. End pipe 15, branch pipe
16. Connection pipe 20 and attachment part
30. A limit ring.
Detailed Description
Referring to fig. 1 and 2, a specific structure of a preferred embodiment of the present invention is shown, which includes a main body 10 and a mounting portion 20 integrally formed and connected in sequence from front to back.
The main body part 10 is internally provided with an accommodating cavity 11 with a forward opening, the top surface of the main body part 10 is provided with an air suction opening 12 and a discharge opening 13 which are communicated with the accommodating cavity 11, an end pipe 14 is arranged in the front end of the main body part 10, a branch pipe 15 is arranged in the rear end of the main body part 10, the branch pipe 15 is communicated with the end pipe 14 through a connecting pipe 16, and the connecting pipe 16 is positioned in the main body part 10.
In this embodiment, the junction between the body portion 10 and the mounting portion 20 is radially enlarged to extend a retainer ring 30. The branch pipes 15 are a plurality of branch pipes 15, and the plurality of branch pipes 15 are sequentially communicated and uniformly distributed on the whole body of the main body 10 in a semi-annular shape. The suction opening 12 is located on the rear side of the feed opening 13.
Detailed description the method of use of this example is as follows:
in use, the mounting portion 20 is fixed to the outside, the molten metal is contained in the containing chamber 11, and the end pipe 14, the branch pipe 15 and the connecting pipe 16 are used for conveying liquid, which may be water or oil. According to different types of the metal liquid injected into the actual accommodating cavity 11, the liquid is different, and the principle is determined according to the requirement of heat conduction of the body. When the injection punch head extends into the accommodating cavity 11 from the opening of the accommodating cavity 11, the air extractor completely extracts the air in the accommodating cavity 11 through the air extraction opening 12, and after the injection punch head enters the accommodating cavity 11, the metal liquid without mixed gas is injected out of the blanking opening 13 and enters the die.
The utility model discloses a design key is: through being provided with the extraction opening, before the injection, the accessible extraction opening is bled the gas in the holding chamber, avoids gas to get into the die cavity of mould along with the molten metal in to avoid various flaws such as bubble to appear in the foundry goods, effectively promoted the shaping quality of foundry goods.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
