Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position adjusting mechanism for a mold cooling water flow path,

More particularly, the present invention relates to a position adjusting mechanism for a mold cooling water flow path interrupter, and more particularly relates to a position adjusting mechanism for a mold cooling water flow interrupter, which is capable of sealing airtightness so as to prevent leakage of cooling water through a flow path interrupting unit, And more particularly, to a position adjusting mechanism of a mold cooling water flow path interrupter which can be easily blocked at a predetermined position.

Generally, a mold is a molding tool used to repeatedly produce a product of a shape suitable for a purpose, and the mold is formed of a water-cooled cooling structure that advances the cooling water to cool the product to be produced.

Such a mold is provided with a plurality of flow passages through which cooling water flows. The flow passages are sealed by watertight sealing to block the leakage of the cooling water. In order to switch the flow direction of the cooling water, Device.

As shown in FIG. 1, a coupling member 300 in which a fastening screw 331 is formed and a fastening screw groove 153 to be screwed into the fastening screw 331 are formed on the inner surface, And an expansion member 200 made of an elastic material which is pressed and externally expanded when the coupling member 300 and the base member 100 are fastened to each other, .

However, when the expanding member 200 is inserted into the flow path in a state that the expansion member 200 is swelled outward by a certain amount due to the engagement of the fastening member 300 and the base member 100, It is difficult to move to a desired position and when the expansion member 200 is joined in a state in which the expansion member 200 is expanded in a degree of outward expansion for easy insertion into the flow path, it is difficult to seal the flow path with watertightness, This leads to serious problems.

In this case, as disclosed in Korean Patent Laid-Open Publication No. 2010-0137740, the base member 50 inserted into the outer surface of the bolt 30 is fastened to the end of the bolt 30 by the coupling force of the nut 60 The nut 60 is inserted into the end of the sealing device 100 inserted into the cooling water passage and fixed to the nut tightening device 70. The bolt 60 is inserted into the end of the sealing device 100 inserted into the cooling water passage, The male screw thread 83 of the bolt fastening device 80 is screwed to the bolt female screw 33 formed at the end of the bolt fastening device 30 so that the bolt fastening device 80 rotates in one direction, 60 to be combined to press the compressible material 90 is disclosed.

That is, in order to improve the sealing force to the cooling water through the hermetic device 100, the compressive material 90 which pressurizes the cooling water path must be pressed. To this end, the nut fastening device 70 and the nut 60 must be firstly joined And then the bolt fixing device 80 and the bolt 30 should be coupled with each other and then the bolt fixing device 80 is rotated with the nut fixing device 70 fixed.

However, the number of manufacturing processes for forming the threads in the bolts 30 and the bolt fastening equipment 80 increases, which increases the manufacturing cost. In order to combine the bolt fastening equipment 80 and the bolts 30, The rotational force must be applied until the end of the mountain 83 and the groove of the bolt female screw 33 come in close contact with each other, and a rotational force must be applied to the opposite side in order to separate them again.

Also, in the initial state where the screw connection is performed even in the visible state, the end portions of the male screw member 83 and the bolt female screw 33 which abut on the male screw member 83 are easily worn. In the state where the closing apparatus 100 is inserted into the passage, The initial bonding is more difficult and the bonding is not easy and the wear rate of each component is increased.

In addition, when the bolt 30 and the bolt fixing device 80 are combined to apply a rotational force so that the inside of the flow path is sealed by the compressible material 90, the threaded portion formed with a relatively thin thickness is broken, .

That is, when the diameter of the bolt female screw 33 is increased, the thickness of the outer surface of the bolt 30 and the inner surface of the bolt female screw 33 becomes thinner, The bolt fastening device 80 formed with a relatively thin thickness compared to the thickness of the bolt female screw 33 may cause cracks or breakage in the case of cracks And broken or broken in a state where the male screw member 83 is coupled to the bolt female screw 33. [

In addition, in order to press the base member 50 by the nut 60 in a state where the male screw member 83 and the bolt female screw 33 are engaged, the nut fastening unit 70 must be firmly fixed. In order to fix the device 70, the user must fix the bolt fixing device 80 with the opposite hand to rotate the bolt fixing device 80, so that not only the efficiency of the operation is remarkably lowered but also the sealing force is different according to the user's force So that it is difficult to maintain a tight and watertight sealing force.

8 (b), when the pressure is applied to both sides of the sealing member 130 by the step portion 124 and the pressing member 140, 130 is further increased, so that the flow path 2 is tightly and tightly sealed to prevent the leakage of the cooling water, thereby improving the airtightness.

At this time, after the flow path interruption unit 100 is moved to a position where the progress of the cooling water is blocked in the flow path 2 through the numerical guide unit 220, the sealing member 130 is pressed in the same manner as described above, The movement of the cooling water can be easily blocked at the set position, and the efficiency of the operation of sealing the flow path 2 in a watertight manner is increased.

In the state where the protruding portion of the adjusting means 200 is inserted into the depressed portion, a force (force) is applied to the inside of the flow path 2 so that the flow path interception unit 100 according to the first embodiment of the present invention can be moved into the flow path 2 The flow path 2 in which the progress of the cooling water is to be cut off can be easily blocked at a predetermined position.

The adjustment means 200 can easily identify and adjust the degree of insertion of the flow path interception unit 100 into the flow path 2 and adjust the position of the flow path interception unit 100 in the state where the connection guide portion 154 And the base member 150 is moved to the side where the base member 150 is coupled to the fastening member 110 so that the pressure applied to the sealing member 130 is increased to maximize the sealing force of the flow path 2 will be.

In addition, the adjustment means 200 can be easily coupled to and separated from the flow path shielding unit 100, and the coupling force of the flow path shielding unit 100 can be increased by a simple operation of the adjustment means 200, There is an effect that the combination of work is increased.

The body 210 according to the second embodiment includes an upper body 270 having a handle 230 and a lower body 280 having a coupling 240 as shown in FIG. The upper support body 271 and the lower support body 281 are formed in correspondence with each other at a portion where the upper body 270 and the lower body 280 are coupled to each other and are fastened by fastening means 290 such as bolts, Which is different from the first embodiment.

As the body 210 is divided into the upper body 270 and the lower body 280, in a process of applying a rotational force to the base member 150 or a process of transporting and storing the control means 200, The lower body 280 can be easily replaced and used when the body 240 is worn or damaged.
