Prior to the description, components having the same configuration are denoted by the same reference numerals as those in the first embodiment. In other embodiments, configurations different from those of the first embodiment will be described do.

Hereinafter, a mold cooling water passage blocking device according to a first embodiment of the present invention will be described in detail with reference to FIGS. 2 to 10 attached hereto.

The mold cooling water flow path blocking device according to the first embodiment of the present invention is for preventing the cooling water from flowing out by sealing the cooling water flow path of the mold and includes a fastening member 100, a body 200, an extension member 300, A base 400, a pressing member 500, and a sealing member 600.

At this time, the fastening member 100 is formed so as to have a wide upper and narrow downward light-tight narrow shape, and a tool engagement groove 111 is formed on the upper surface thereof. The lower surface of the fastening member 100 has a head portion 110 formed on an inclined surface, And a bolt portion 120 having threads formed on an outer surface extending downward from the lower surface of the central portion.

The body 200 is provided with a through hole 220 through which the bolt 120 is inserted and a head receiving groove for receiving and mounting the head 110 in a state where the bolt is inserted into the upper surface of the body 200 And is formed in a shape corresponding to the inclined surface of the head part 110, and the lower surface is formed flat.

The expansion member 300 is compressed and expanded by the engagement of the fastening member 100 and a base 400 to be described later and is inserted into the outer surface of the bolt portion 120, .

As shown in FIG. 5, the extending member 300 includes a protruding support portion 310 formed in a radial shape and protruding from the outer circumferential surface toward the central axis, And a bent portion 320 which is bent in an arc shape so as to have a shape protruding upward from the protruding support portion 310 and which is deformed into a flat shape by the engagement of the fastening member 100 and a base 400 to be described later Do.

The reason why the depression 311 is formed is that the bending portion 320 is pressed so as to have the same height as the protrusion supporting portion 310 by the engagement of the coupling member 100 and the base 400, 320 and the protruding support 310 are pressurized to the same height and are then further pressurized.

The protruding support 310 and the protruding support 320 may be easily formed using a pressing device such as a press. The protruding support 310 and the protruding support 310 may be formed as shown in FIG. One or more bent portions 320 may be formed.

At this time, the expansion member 300 may increase the number of times the bent portion 320 is bent to improve the coupling force. However, when the bent portion 320 is formed too much in the protruding support portion 310 having a limited size, The bending portion 320 may be formed in an appropriate number in consideration of the size of the protrusion support portion 310. As a result,

7, the extension member 300 may be formed by varying the number of the protrusion support portions 310. However, when the protrusion support portion 310 is formed with too many depressions 311, Since the connecting portion of the protruding support 310 is relatively thin and the connecting portion may be broken or broken during the coupling process through the coupling member 100, the size and number of the protruding support 310 must be formed in consideration thereof .

The base 400 includes a coupling portion 410 having a screw groove on an inner surface thereof to be screwed to the bolt portion 120 at a lower portion of the expansion member 300, And a receiving portion 420 having a diameter is formed.

The coupling portion 410 and the receiving portion 420 may be formed of a metal material or may be formed of synthetic resin such as nylon 66 only through the receiving portion 420, And the nylon 66 material described above has improved heat resistance, elastic modulus, abrasion resistance, chemical resistance, and corrosion resistance.

The pressing member 500 is inserted into the fastening member 100 to the lower side of the expansion member 300 and supports the expansion member 300 to be compressed and expanded by the engagement of the fastening member 100 and the base 400, Is formed so as to be in close contact with the lower surface of the extension member (300).

At this time, the size of the insertion hole 510 formed at the center of the pressing member 500 depends on the height of the coupling part 410, the size of the sealing member 600, the number of the sealing members 600 coupled to the base 400 Or may be formed to have a size that can be inserted into the outer surface of the coupling portion 410 constituting the base 400 or may be sized to be supported on the upper surface of the coupling portion 410.

The sealing member 600 is made of a ring-shaped elastic material which is compressed and expanded by the engagement of the coupling member 100 and the base 400. The sealing member 600 is formed of a ring- It is preferable to insert a supporting member 700 having a size that can be inserted into the outer surface of the coupling part 410 between the adjacent sealing members 600 when the two or more pieces are inserted .

As shown in FIG. 4, the upper and lower surfaces of the support member 700 may be formed with a plurality of recesses and protrusions 710 in order to improve the adhesion with the sealing member 600. Although not shown, The concave portion and the groove portion may be continuously formed on the upper surface to improve the adhesion with the sealing member 600 or the outer circumferential surface of the receiving portion 420 may be knurled to prevent slip during initial engagement.

The pressing member 500 and the supporting member 700 are made of metal or synthetic resin. The sealing member 600 is made of a rubber material such as rubber Or urethane or the like.

Hereinafter, the operation of the mold cooling water passage blocking device having the above-described structure will be described.

The sealing member 600 is inserted into the outer surface of the coupling part 410 and the body 200 and the expansion pad and the pressing member 500 are sequentially inserted into the lower side of the coupling member 100, Screw the threads of the bolt part (120) into the thread groove.

8, at the initial stage of screw connection between the fastening member 100 and the base 400, the refracted upper portion of the bent portion 320 is supported on the lower surface of the body 200, When the fastening member 100 and the base 400 are fastened together, the bent portion 320 is pressed through the pressing member 500 and the body 200 to be gradually deformed to the same height as the protruding and supporting portion 310, 100 and the base 400 are further tightened, the upper surface and the lower surface of the expansion member 300 are tightly coupled to the lower surface of the body 200 and the upper surface of the pressing member 500, respectively.

As described above, the refracting portion is deformed into a flat state by the engagement of the fastening member 100 and the base 400, and the upper and lower surfaces of the extending member 300 are closely contacted and supported together with the protruding support portion 310, The lower surface of the body 200 and the upper surface of the pressing member 500 are formed flat.

As a result of the bent member 320 being deformed into a flat shape bent upward by the engagement of the fastening member 100 and the base 400, 200 and the upper surface of the pressing member 500 and is formed of a metal material so that even if the bent portion 320 is deformed into a flat state, The coupling force between the coupling member 100 and the base 400 is improved and the coupling state between the coupling member 100 and the pressing member 500 is improved. .

The expansion member 300 compressed and expanded by the engagement of the coupling member 100 and the base 400 is extended outward by the bent length of the bending portion 320, Even if the internal pressure of the flow path increases due to the supply of the fluid, the position can be firmly maintained in the state of being inserted into the flow path.

In addition, the size of the hole 330 formed at the center of the expansion member 300 may be formed to be large enough to be inserted into the outer surface of the coupling part 410 in order to insert the bolt part 120, It is not easy to form the bending portion 320 because the supporting portion 310 has to be formed in a small area, and there is a possibility that the contact supporting area becomes narrow and the bonding force is weakened to some extent. Therefore, It is preferable that the holes 330 formed in the bolt portion 120 have a size corresponding to the diameter of the bolt portion 120.

At this time, the initial engagement position may be changed according to the size of the insertion hole 510 at the center of the pressing member 500. When the insertion hole 510 is formed to have a size corresponding to the through hole 220 formed in the body 200 That is, when the lower surface of the pressing member 500 adjacent to the insertion hole 510 is formed to have a size capable of being seated and supported on the upper surface of the coupling part 410, it is preferable that the coupling is inserted into the outer surface of the bolt part 120 And when it is formed to have a size corresponding to the outer diameter of the coupling part 410, it is preferable that the coupling part 410 is inserted into the outer surface of the coupling part 410 with the sealing member 600 inserted therein.

When the extension pad is pressed, the pressing member 500 is folded so that the bent portion 320 is flat and supported on the lower surface of the body 200 and the upper surface of the pressing member 500 together with the protrusion supporting portion 310 The sealing member 600 is compressed and expanded through the upper surface of the receiving unit 420 and the lower surface of the pressing member 500. The size of the insertion hole 510 is set to be a size corresponding to the through hole 220 The area of contact with each other is widened so that the expansion pad can be easily expanded and compressed to seal the inside of the flow path while maintaining a firm connection state.

The upper surface of the coupling part 410 does not protrude upward from the closure member 600 when the upper surface of the coupling part 410 is protruded or inserted into the upper side of the closure member 600 coupled to the base 400 When the sealing member 600 is pressed by the coupling member 100 and the base 400 and the sealing member 600 can be protruded upward from the sealing member 600, So that the sealing member 600 is pressed together with the protruding support portion 310 and the bending portion 320 of the expansion member 300 through the pressing member 500. Thus, It is possible to maintain the tightly coupled state.

When the insertion hole 510 is formed to have a size corresponding to the outer diameter of the coupling part 410, the lower surface of the extension member 300 is connected to the rim of the protrusion supporting part 310 including the bending part 320, The upper and lower surfaces of the extension member 300 are supported by the upper surface of the pressing member 500 and the portion between the rim portion and the center hole 330 is supported through the upper surface of the coupling portion 410, The lower surface of the body 200 and the upper surface of the engaging portion 410 can be tightly coupled with each other while being closely contacted with each other.

9 and 10, when two or more sealing members 600 are coupled to the base 400 and the supporting member 700 is inserted between the sealing members 600, The upper surface of the engaging portion 410 can be prevented from protruding upward from the closure member 600 even when the closure member 600 is compressed by the engagement of the insertion hole 400, 220 or a size that can be inserted into the outer diameter of the coupling part 410. [

Even when the two or more sealing members 600 are coupled to each other, regardless of the fact that the sealing member 600 is compressed and expanded so that the upper surface of the coupling portion 410 protrudes to the upper side of the sealing member 600, It is preferable that the insertion hole 510 is formed to have a size corresponding to the outer surface of the coupling portion 410 in order to pressurize the inside of the flow passage sufficiently by sealing the connection portion .

The lower surface of the body 200 which is in contact with the expansion member 300 which is expanded and expanded by the coupling force between the fastening member 100 and the base 400 and the lower surface of the body 200, By omitting the tapering step, productivity and work efficiency are improved, and manufacturing cost is reduced.

The extended member 300 extends to the outer peripheral surface side by the bent length of the bent portion 320 in a state in which the extended member 300 is held in close contact with the body 200 and the pressing member 500 to have a wide contact area, The coupling state is maintained to prevent any flow due to the pressure of the cooling water, and the inside of the flow path can be sealed by the sealing member 600 in a watertight manner.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
