Description

COOLING DEVICE FOR FORMING APPARATUS OF GLASS}

The present invention relates to a cooling device for a glass product forming facility, and more particularly, to a cooling device for a glass product forming facility that can more effectively adjust the rotation angle of the inner basket.

In general, when the molten glass is provided to the lower mold from the melting furnace (not shown), the glass product is formed by lowering the plunger (not shown) disposed coaxially with the lower mold to pressurize the glass contained in the lower mold. The glass material provided in the mold is formed into a glass product, and after this process is completed, when the molded glass product is taken out, a cooling process for cooling the lower mold at which the temperature is raised by press molding of the glass product is performed. do.

When the cooling process of the lower mold is reached, as shown in FIG. 6, in the pair of cylinders 160a and 160b, for example, the arm arm 146 is counterclockwise by the right cylinder 160a. It rotates a predetermined distance, thereby the inner basket 136 coupled to both arms 146 also rotates in the rotational direction of both arms 146, so that the sidewall openings 138 and 130 between the inner and outer baskets 136 and 126 communicate with each other. Done. As such, when the side wall openings 138 and 130 between the inner and outer baskets 136 and 126 communicate with each other, the air flowing into the turntable (not shown) is connected to the lower mold through the air outlet on the turntable through the side wall openings 138 and 130 connected thereto. By being discharged to the cooling process of the lower mold is started.

Next, when a predetermined time elapses, both arm arms 146 are rotated in the opposite directions by the left cylinder 160b, so that the sidewall openings 138, 130 between the inner and outer baskets 136, 126 are blocked from each other, thereby lowering the lower mold. The cooling process of the stage will end.

By the way, in such a conventional cooling device for glass molding equipment, there is a problem that it is very difficult to adjust the rotation angle of the inner basket 136 in the forward and reverse directions with respect to the outer basket 126.

That is, in order to completely open the side wall openings 138 and 130 between the inner and outer baskets 136 and 126, or to open them halfway, the rotation angle of the inner basket 136 must be controlled. To this end, it is necessary to control the angle of rotation of the arm arm 146 to rotate the inner basket 136, for this purpose, conventionally depends only on the operating pressure of the cylinder (160a, 160b) for pressing both ends of the arm arm 146 Since it was necessary to control the rotation angle of the inner basket 136 was very difficult. In addition, when the rotation angle of the arm arm 146 cannot be accurately controlled despite the adjustment of the operating pressure supplied to the cylinders 160a and 160b, the fixing block 164 for fixing the cylinders 160a and 160b is disassembled again. There is a problem that the cylinder (160a, 160b) must be rearranged.

Therefore, as described above, if the rotation angle of the inner basket 136 can be easily and effectively adjusted without replacing or reinstalling the equipment, it is possible to reduce the process loss due to the replacement and reinstallation of the equipment as well as to shorten the time. To maximize.

Accordingly, it is an object of the present invention to provide a cooling apparatus for a glass product forming facility, which enables to more effectively adjust the rotation angle of the inner basket.

The turntable 14 is formed with an air discharge port 22 upwardly opened to discharge the air flowing in the lower mold air duct 18, which will be described later. The lower molds 20 forming the station are stacked along the circumferential direction. A pedestal 24 for supporting the lower mold 20 is standing up between the lower mold 20 and the turntable 14.

The inside of the turntable 14 is discharged to the turntable air duct 16 through which air is circulated for cooling the turntable 14 itself, and to the air outlet 22 formed on the turntable 14, A plurality of air ducts 16 and 18 are respectively divided into air mold ducts 18 for lower molds for cooling the lower molds 20 arranged in the upper region.

In the lower duct air duct 18 below the air discharge port 22, the fixing part 28 and the other end of which are screwed onto the turntable 14 so as to open upwardly communicate with the air discharge port 22 are connected to the turntable ( A basket-shaped outer basket 26 is fixed to the lower basket accommodating part 34 of 14) and has a cylindrical side wall part 32 in which a plurality of side wall openings 30 are formed. A rotating shaft 44 is formed inside the outer basket 26 so as to be capable of forward and reverse rotation within a predetermined angle range with respect to the fixed outer basket 26, and selectively open and close the sidewall opening 30 of the outer basket 26. A cylindrical inner basket 36 having a side wall portion 40 having a plurality of side wall openings 38 is also provided. In the inner basket 36, a cone-shaped air guide member 42 is installed to smoothly guide air upward.

On the other hand, the lower side of the inner basket 36, the arm arm 46 is coupled to the lower end of the rotary shaft 44 is provided, between the arm arm 46 and the turntable 14 is inserted into the rotary shaft 44 and the lower end A bush 48 having a cross-sectional shape 'ㅗ' fixed to the plate surface of the arm arm 46 is provided. On the outer side of the bush 48, one end contacts the flange portion 50 of the bush 48 and the other end contacts the lower end portion of the turntable 14, thereby riding the inner basket 36 against the outer basket 26. A plurality of coil springs 52 that are sexually supported are provided.

A boss hole 45 is formed on the plate surface of both arms 46 to form a shape with the boss portion 41 formed on the rotating shaft 44, and bolt holes 54a having female threads formed at both ends of the arms arm 46. 54b) is formed. And, each of the bolt holes (54a, 54b) is screwed adjustable length adjustment bolts (56a, 56b), and the end region of each of the adjustment bolts (56a, 56b) is coupled to each bolt hole (54a, 54b) An anti-separation nut 58 for preventing detachment of the adjusting bolts 56a and 56b is fastened. On the other hand, in front of each of the adjustment bolt (56a, 56b) having a rod extending length (62a, 62b) are arranged in parallel to each other in the horizontal direction with respect to the longitudinal direction of both arms (46) to adjust each adjustment bolt (56a, 56b) A pair of pressing members 60a and 60b for linearly pressurizing in the plane of rotation are provided by separate fixing blocks 64.

By this configuration, when the molten glass is provided to the lower mold 20 from the melting furnace not shown, a plunger (not shown) disposed coaxially with the lower mold 20 is lowered to be accommodated in the lower mold 20. Pressurize the glass. When the glass product is molded by pressurizing the plunger, air is supplied to the lower mold air duct 18 in the turntable 14 to cool the lower mold 20 whose temperature is increased according to the pressing of the glass product.

When air starts to flow into the lower mold air duct 18, a pair of pressure members 60a and 60b are supplied with a working fluid to extend the lengths of the rods 62a and 62b of the pressure members 60a and 60b. To be reduced or reduced. Here, for convenience of description, the right side pressing member 60a, the rod 62a, and the adjusting bolt 56a, etc. are used as a modifier 'right', and the left side pressing member 60b, rod 62b on the drawing. ) And the adjustment bolt 56b, etc., a modifier of 'left' is used, and side wall openings 38 and 30 between the inner and outer baskets 36 and 26 communicate with each other by the operation of the right pressing member 60a and the left pressing member. It is assumed that the side wall openings 38 and 30 between the inner and outer baskets 36 and 26 are mutually blocked by the operation of 60b.

First, when the right pressing member 60a is operated to extend the length of the right rod 62a, the right rod 62a presses the end of the right adjusting bolt 56a in the rotational plane so that both arm arms 46 The predetermined angle is rotated counterclockwise around the axis. When the arm arm 46 rotates, the rotation shaft 44 coupled thereto also rotates counterclockwise, so that the side wall opening 38 of the inner basket 36 is shown in FIG. It coincides with the side wall opening 30 of the outer basket 26. At this time, the side wall openings 38 and 30 between the inner and outer baskets 36 and 26 are not necessarily matched as shown in FIG. 5A, and in some cases, as shown in FIG. 5C, The side wall openings 38 and 30 between the inner and outer baskets 36 and 26 are half-opened so that the temperature gradient due to the cooling of the lower mold 20 may be appropriately compensated.

As such, when the side wall openings 38 and 30 between the inner and outer baskets 36 and 26 coincide with each other, the air supplied into the lower mold air duct 18 passes through the side wall openings 38 and 30 communicating with each other. It is introduced into the inner basket 36, the air is guided upward by the air guide member 42 is directed to the lower mold 20 through the air discharge port 22 to cool the lower mold 20.

Next, when the cooling process of the lower mold is finished after a predetermined time has elapsed, the left pressing member 60b is operated to extend the length of the left rod 62b, whereby the left rod 62b has a left adjusting bolt ( By pressing 56b) in the rotation plane, both arms 46 are rotated a predetermined angle in the opposite direction, that is, clockwise. When both arm arms 46 rotate, the inner basket 36 also rotates a predetermined angle clockwise, so that the side wall opening 38 of the inner basket 36 has an outer basket 26 as shown in FIG. The side wall opening 30 of the) is blocked, and thus, the cooling process of the lower mold 20 is completed.

On the other hand, if the above process is repeatedly performed due to external vibration or aging of the equipment, the right pressing member (60a) is operated so that the right rod 62a in spite of pressing the right adjusting bolt (56a) inside and outside the basket The side wall openings 38 and 30 between the 36 and 26 do not coincide with each other.

In this case, the length of the adjustment bolts 56a and 56b according to the present invention is adjusted as follows.

That is, bolt holes 54a and 54b having female threads are formed at both ends of both arm arms 46, and adjusting bolts 56a and 56b which are length-adjusted are screwed to each bolt hole 54a and 54b. When the side wall openings 38 and 30 between the inner and outer baskets 36 and 26 do not coincide with each other, that is, when the rotation angle of the inner basket 36 does not reach a predetermined angle, first, the release preventing nut 58 Loosen the right adjustment bolt 56a is adjusted to protrude a predetermined distance toward the right pressing member (60a) from the plate surface of both arms arm (46). This is because the maximum extension length of the right rod (62a) is already determined, unless the position of the right pressing member (60a) is already fixed fixedly, on the contrary, the separation distance between the right adjusting bolt (56a) and the right rod (62a) In short, the angle of rotation of the arms arm 46 by the extension of the length of the right rod 62a is increased by that, so that the angle of rotation of the inner basket 36 can also be widened.

Therefore, when adjusting the protruding length of the right adjusting bolt 56a, it is appropriately adjusted in consideration of the maximum extension length of the right rod 62a. When the adjustment of the protruding length of the right adjusting bolt 56a is completed, tighten the release preventing nut 58 to the right adjusting bolt 56a to fix the right adjusting bolt 56a to the right bolt hole 54a. In the operation of 60a, the side wall openings 38 and 30 between the inner and outer baskets 36 and 26 can be matched with each other.

As such, in the present invention, by providing the length-adjustable adjusting bolts 56a and 56b at both end sides of the arm arm 46, the rotation angle of the inner basket 36 can be adjusted very easily.

As described above, according to the present invention, there is provided a cooling apparatus for molding a glass product to make it easier and more effective to control the rotation angle of the inner basket.
