Description

Tilt casting apparatus that rotates in two axes}

The present invention relates to a two-axis rotation tilt casting device, and more specifically, in gravity casting in which the molten metal filled in the molten metal injection space is injected into the cavity by gravity, the mold is formed in a first direction and perpendicular to the first direction. It relates to a two-axis rotation tilt casting device that is configured to rotate in two directions in a complex manner, so that molten metal can be uniformly supplied to the entire cavity even when the cavity shape inside the mold is complex.

In general, gravity casting is a method of forming a desired casting by temporarily storing molten metal in a bucket and then rotating the mold to inject the molten metal into the cavity of the mold by gravity. There are two types of gravity casting methods: static casting and tilt casting.

The stationary gravity casting is configured to produce a product by having the worker directly inject molten metal into the inside of a fixed mold through a ladle, allowing the flow of molten metal to fill the inside of the mold by gravity. Since injection is performed, the injection speed of the molten metal charged into the injection port cannot be adjusted.

In addition, the tilting type gravity casting is equipped with a molten metal injection cup connected to the molten metal injection port, and the mold is tilted with molten metal supplied to the molten metal injection cup, so that the molten metal in the molten metal injection cup flows into the mold through the injection port at once. As a method for supplying molten metal, it has the feature of being able to set the molten metal injection speed equally for each injection port.

For example, in Patent Document 1 below, a mold frame is hinged to one end of a stand and installed to be rotatable, a hydraulic cylinder installed between the stand and the mold frame so as to rotate the mold frame, and a fixing device installed inside the mold frame. A mold and a movable mold, a hydraulic cylinder installed to move the movable mold, a cavity and an injection port formed on the contact surface of the fixed mold and the movable mold, and a water supply installed to temporarily store molten metal at the tip of the injection port, the water supply of the water supply. A tilt-type gravity casting machine including a blowing means installed at the top of the outlet tip is disclosed.

Through this, the tilt-type gravity casting machine of Patent Document 1 below can prevent defects in castings in advance by blocking the oxide film formed on the surface of the molten metal from flowing into the cavity through the blowing means, which has the effect of improving the quality of the product. There is.

However, since Patent Document 1 uses a hydraulic cylinder to rotate the mold to inject molten metal stored in water into the cavity, it is not easy to control the rotation angle and rotation speed of the mold.

In addition, since Patent Document 1 is a method of supplying molten metal stored in the water to the cavity by rotating the mold frame only on one axis, if the shape of the cavity is complex, the molten metal cannot be supplied uniformly throughout the cavity, making it difficult to produce a casting of uniform quality overall. There is a problem that cannot be cast.

In addition, in Patent Document 2 below, a rotating frame is installed so as to be rotatable up and down by coupling a rotating shaft to the main body of the casting machine, a mold part installed on the rotating frame and consisting of a fixed mold and a moving mold, and having a cavity formed therein, and the fixed mold. It is installed on one side of the molten metal bucket part where molten metal for injection into the cavity is temporarily stored, and the rotating frame is rotated so that the molten metal stored in the molten metal bucket part is injected into the cavity by gravity, and the molten metal is injected into the cavity. Disclosed is a gravity sodium bicarbonate generator including a rotation driver capable of tilting and controlling the rotation angle and speed of the rotation frame in order to control the flow of the molten metal.

Through this, Patent Document 2 has the effect of improving the quality of castings by smoothly controlling the flow of molten metal injected into the mold by precisely tilting and controlling the rotation angle and speed of the mold frame using a tilting servo motor. .

However, Patent Document 2 solved the problem of not being able to control the rotation angle and rotation speed of the mold frame in Patent Document 1 below, but since the mold frame is rotated only along one axis to inject molten metal into the cavity, the shape of the cavity In complex cases, there still remains the problem of not being able to supply molten metal uniformly throughout the cavity.

Republic of Korea Patent No. 10-0370891 (announced on March 15, 2003) Republic of Korea Patent Publication No. 10-2016-0113838 (published on October 4, 2016)

The rotation unit further includes a crank module that converts the linear motion of the first and second rotation cylinders into rotational movement of the rotation portion at the coupling portion of the first and second rotation shaft supports and the first and second rotation cylinders, respectively. Contains,
The crank module includes a first hinge respectively coupled to one side of the first or second rotation shaft support, a second hinge coupled to the other end of the first or second rotation cylinder, the first hinge, and the second hinge, respectively. A two-axis rotary tilt casting device comprising a pair of connecting crank arms.
In paragraph 2,
The control unit controls the rotation motor and the first and second rotation cylinders to adjust at least one of a rotation angle or a rotation speed of the mold unit and the rotation unit.
In paragraph 2,
The mold part
A mold panel disposed parallel to the pivoting panel,
First and second mold supports provided at both ends of the mold panel and rotatably coupled to the first and second pivot shaft supports, respectively;
A lower mold provided on the mold panel,
An elevating panel provided to be movable in the vertical direction at the top of the lower mold, and
A two-axis rotary tilt casting device comprising an upper mold provided at a lower part of the lifting panel and coupled to the lower mold when the lifting panel is lowered to form a cavity therein.
In paragraph 6:
The mold panel is provided with a molten metal injection space on one side of the lower mold, and a molten metal injection space is formed between the lower mold and the molten metal injection space. A two-axis rotary tilt casting device, characterized in that.
In paragraph 6:
A two-axis rotary tilt casting device further comprising a plurality of lifting shafts provided on one side of the mold panel to support the lifting panel so that it can move in the vertical direction.
In paragraph 8:
It further includes a lifting part provided to raise and lower the lifting panel at the upper part of the mold part to combine or separate the lower mold and the upper mold,
The lifting part
A lifting support panel to which an end of the lifting shaft is fixedly coupled,
A two-axis rotary tilt casting device comprising a lifting cylinder fixed to a central portion of the lifting support panel and moving the lifting panel in an up and down direction.
