Description

CONFIRMATION DEVICE OF COOLING WATER FOR MOLD

The present invention relates to a device for identifying the flow of cooling water used in a mold and a device for identifying the flow of the cooling water by visually identifying the flow of the cooling water.

In the mold, a cooling fluid, that is, a passage through which the cooling water flows can be made to flow a certain amount of cooling water to cool the mold.

This is to keep the temperature of the mold constant or to adjust to the temperature according to the fill, and it is very important to control the flow rate of the cooling water appropriately in this cooling technique. If the flow rate of the cooling water is too low, there is a risk that the cooling may not be sufficiently performed and a problem due to overheating may occur.

As a technique for checking the flow of cooling water in a mold, Korean Utility Model Registration No. 0461928 (2012.08.08, a cooling fluid identification device for a mold) is disclosed.

As shown in FIGS. 1 and 2, the above-described technique is interposed in the piping of the cooling water pipe through which the cooling water of the mold flows, and a connecting portion 12 for connecting to the cooling fluid pipe P is installed at both ends (10) whose middle portion is a transparent or translucent material (11); A rotary blade 20 fixedly installed inside the perspective body 10 and rotated about a shaft X perpendicular to the duct by a flow of a cooling fluid; A blade mounting means for fixing the rotary vane 20 to the inside of the transparent tube 10; A wiping means 40 installed at an end of the rotary vane 20 for contacting the inner wall surface 11a of the transparent tube 10 as the rotary vane 20 is rotated about the axis X, ).

The above technology has an advantage that the flow of the cooling water can be visually confirmed easily due to the rotating blades. However, since the rotating blades located behind the two rotating blades are likely to rotate in the reverse direction, the cooling water can not smoothly advance, When the pressure of the cooling water is lower than a certain pressure due to the state in which the means is in contact with the inner wall surface of the penetration tube, the cooling water can not be easily rotated.

In addition, the above-described technology has disadvantages and difficulties in manufacturing due to its installation structure, resulting in not only poor workability but also an increase in purchase cost due to an increase in cost.

Korea Registered Utility Model No. 0461928 (2012.08.08, cooling fluid identification device for mold)

The object of the present invention is to visually confirm the flow state of the cooling water, to smoothly advance the cooling water through the structure improvement, Thereby preventing the possibility of backflow of the cooling water generated in the mold cooling water flow detecting device.

In order to achieve the above object, the present invention provides a cooling water pipe connected to a cooling water passage of a metal mold, wherein a transparent cover (110) for opening and closing the inside is installed on one side, A cylindrical housing 100 having a shaft 120 protruding in the installation direction of the cooling water 110 and partially or wholly made of a transparent material so as to visually confirm the flow of the cooling water; An inlet 200 formed at one side of the housing 100 and facing the inner circumferential surface of the housing 100 to receive cooling water into the inside of the housing while flowing cooling water toward the inner circumferential surface of the housing; An outlet 300 formed at a portion of the other side of the housing 100 that is diagonally opposite to the inlet 200 to allow the cooling water flowing into the housing 100 to flow out in the same direction as the inlet direction; A plurality of first wings 410 and second wings 420 having a different length on the outer circumferential surface are inserted into the shaft 120 of the housing 100 and rotated inside the housing by the flow of cooling water, The first wing 410 is formed so as to be close to the inner circumferential surface of the housing 100 and the second wing 420 is formed between the first wing 410 and the first wing 410, And a rotary blade (400) having a length shorter than the length of the first wing (410).

At this time, it is preferable that a filtration filter 500 is installed at the inlet side of the inlet 200 so as to filter foreign substances present in the cooling water.

According to the mold cooling water flow check apparatus having the above-described structure, the flow of the cooling water can be smoothly monitored by blocking the reverse flow of the cooling water, which may be generated in the rotating operation of the rotary vane, There is an effect.

Hereinafter, a mold cooling water flow check apparatus according to a preferred embodiment of the present invention will be described in detail.

2 is a perspective view of a mold cooling water flow check apparatus according to the present invention, FIG. 3 is an exploded perspective view of a mold cooling water flow check apparatus according to the present invention, FIG. 4 is a sectional view of FIG. 2, And the installation state of the cooling water flow check device.

As shown in the figure, the mold cooling water flow check apparatus according to one embodiment of the present invention is interposed in a cooling water pipe P connected to a passage formed in the mold M, Install it on the side.

The present invention includes a cylindrical housing 100, an inlet port 200 and an outlet port 300 respectively formed at the inlet and outlet of the housing 100, and a rotary vane 400 installed inside the housing have.

The housing 100 is partially or wholly made of a transparent material so that the flow of the cooling water can be visually observed. A transparent cover 110 is installed on one side of the housing 100 so that the rotary vane 400 can be installed therein .

The transparent cover 110 is formed of a transparent material so as to be detachably attached to the housing 100 and is detachable from the outside.

Although the transparent cover 110 is coupled to the housing 100 in a spiral connection manner in the accompanying drawings, the transparent cover 110 can be connected to the housing in any manner.

The inlet port 200 and the outlet port 300 are formed to allow cooling water to flow into and out of the housing 100. The inlet port 200 is formed at a portion of one side of the housing 100, And the outlet 300 is formed at a portion of the other side of the housing 100 at a position not facing the inlet 200.

The inlet port 200 is formed so as to face the inner circumferential surface of the housing in such a manner that the cooling water flowing through the inlet port flows into the inner circumferential surface of the housing, So that it can be used.

At this time, the outflow ports 300 may be formed so as to be parallel to each other with respect to the inlet port 200, so that cooling water flows in the same direction.

Accordingly, the cooling water introduced through the inlet 200 moves along the inner circumferential surface of the housing while rotating the rotary vane, and then flows out through the outlet 300. [

Although not shown, the outflow ports 300 are formed so as to form obtuse angles inside and are directed in different directions, not in the same direction, so that the cooling water introduced through the inlet port is moved along the inner circumferential surface of the housing, .

The rotary vane 400 is inserted into the housing 100 and is rotated about the shaft 120 by the flow of the cooling water. The operator can visually confirm the flow of the cooling water by rotating the rotary vane 400 .

The rotary vane 400 has a plurality of first vanes 410 and a plurality of second vanes 420, which have different lengths on the outer circumferential surface of the rotary vane 400, and are alternately formed at regular intervals.

The first wing 410 is formed so as not to contact the inner circumferential surface of the housing 100 and the second wing 420 is formed between the first wing 410 and the first wing 410, As shown in FIG.

The first wing and the second wing are guided to be smoothly rotated by the cooling water. The reason why the first wing is formed long is that it flows into the housing and then flows out through the outlet in the rotating process of the rotating wing To minimize the reverse flow of the cooling water through the space between the inner peripheral surface of the housing and the end of the first wing.

At this time, it is preferable that the first wings are formed at intervals of 90 degrees so as to minimize the reverse flow of the cooling water. This is because the first wing is opposed to the cooling water flowing through the inlet port at a right angle so that the adjacent first wing is not positioned at the inlet port so that the pressure of the cooling water flowing into the first wing acts on the facing first wing, So as not to interfere with the flow.

The inlet (200) and the outlet (300) may be directly coupled to the cooling water pipe by being spirally connected, or may be connected to separate piping components.

On the other hand, a filtration filter 500 may be installed at the inlet side of the inlet 200 to filter foreign substances present in the cooling water. The foreign matter existing on the cooling water can be filtered by the installation of the filtration filter to prevent damage to the rotating blades, as well as to reduce the load of foreign matter on the inner peripheral surface of the housing, It is possible to solve the problem that it is not smoothly performed.

According to the present invention configured as described above, the cooling water flowing in the direction of the inner circumferential surface of the housing through the inlet port 200 moves along the inner circumferential surface of the housing while pushing the first and second vanes under pressure, 300).

At this time, the pressure of the cooling water flowing into the inlet port acts on all of the first vanes, so that the first vanes can be rotated effectively, and the first vanes are as close as possible to the inner circumferential surface of the housing, The reverse flow of the cooling water can be prevented or minimized.

Meanwhile, the operator visually confirms the rotating state and the rotating state of the rotating blades, and can determine the moving state of the cooling water flowing into the housing through the inlet of the housing through the inlet port, the flow rate of the cooling water flowing out of the outlet port, and the moving speed.
