Description

Angle ring forming device capable of adjusting the inner and outer diameter size}

In the present invention, the first and second molding units can produce pipe-shaped moldings and mass-produce angular rings through cutting, thereby increasing productivity and economic feasibility, and in particular, producing various angular rings having different inner and outer diameter sizes in one mold. In addition, it is possible to adjust the size of the inner and outer diameters of each ring through various combinations of the first and second molding parts, so that not only standard products but also angular rings other than standard products can be manufactured.

Compared to plastic, metal, ceramic materials, etc., rubber material has excellent sealability, elasticity, shock absorption, etc. It is an important material.

In order to prevent leaks and leaks of gas and fluid, packing is required in areas where airtightness is required, and rubber packing is currently widely used. There are various types of packing, but not only O-rings that form the shape of donuts, but also angular rings are widely used.

These angular rings are generally manufactured by an injection molding method using a mold or a method of attaching an end of a band through manual labor of a worker using a band-type material.

In the case of mass production of angular rings of standardized sizes, it may be suitable to produce them by the injection molding method, but in the case of small-quantity production of various angular rings that are not standardized, it may be more effective to produce them through the operator's manual work rather than the injection molding method.

In the latter method, in which each ring is produced through the manual labor of a worker, the operator joins the ends of the band in advance and then forms a desired shape of each ring through a press molding process, or overlaps the ends of the band with each other and then presses the ends of the band through a press molding process. At the same time as bonding, it may be performed in a manner of forming an angular ring of a desired shape. To this end, a molding mold having a molding groove having a desired shape is required.

Conventional forming molds are generally composed of an integrated upper mold and lower mold in which molding grooves are respectively formed. Therefore, in the case of the existing forming mold, when the upper or lower mold is damaged through repeated molding processes, there is a problem in that the entire damaged mold must be discarded. In addition, in the case of existing molding molds, once molding grooves are formed in the upper and lower plate molds, each ring molding operation is possible only for rubber materials having a shape or size corresponding to the formed molding grooves. That is, the conventional molding mold has a problem in that it is difficult to change the shape or size of a rubber material that can be molded, and it is ineffective for molding angular rings having various shapes or sizes in a small amount.

As shown in FIGS. 1 to 3, the first molding part 50 and the second molding part 60 according to the present invention are configured to manufacture a pipe or a cylindrical molding M in order to manufacture an angular ring AR. do.

First, the first molding part 50 is formed in a cylindrical shape, and the outer diameter size of each ring AR is determined by molding the outer circumferential surface of each ring AR by means of the inner diameter part 51.

Next, the second molding part 60 is formed in a round bar shape, and the inner diameter size of each ring AR is determined by molding the main surface of the angular ring AR with the outer diameter part 61.

To this end, each of the upper ends of the first and second molding parts 50 and 60 are supported by the first insertion part 30 and each lower part is supported by the second insertion part 40. Since the structure of the first and second insertion parts 30 and 40 has been described, it will be omitted to avoid redundant description.

The inner diameter part 51 of the first molding part 50 and the outer diameter part 61 of the second molding part 60 according to the present invention are spaced apart from each other to form a molding space S, and the molding space S A pipe-shaped molding (M) is produced by putting rubber or a similar material, which is the material of each ring (AR), in the form of resin on the top. It is possible to manufacture several angular rings (AR) at once by cutting the molded article (M) produced in this way according to the thickness required by the product.

In the case of individually molding each ring (AR) as in the prior art, even if a plurality of molding parts are disposed on one mold, there is a limit to the amount of production. Therefore, in the case of individually molding each ring (AR) as in the prior art, not only does it take a lot of time when there is a large order, but there is a problem of poor productivity and economic efficiency.

In contrast to this, as shown in FIG. 4, after manufacturing the molded product M in the form of a pipe by the first and second forming parts 50 and 60 according to the present invention, it is cut to the thickness according to the order and each ring Mass production becomes possible by manufacturing (AR). For example, assuming that an 80 cm long pipe-shaped molding M is manufactured by the first and second molding parts 50 and 60, 80 angular rings AR are manufactured by cutting 1 cm thick angular rings AR, , It is possible to manufacture 160 angular rings (AR) through cutting the angular ring (AR) having a thickness of 0.5 cm.

Therefore, it has the advantage of being efficient in terms of productivity as well as economic efficiency.

Furthermore, the first molding part 50 and the second molding part 60 according to the present invention can manufacture angular rings (AR) of various sizes, for example, when manufacturing angular rings (AR) having the same inner diameter but different outer diameters. The second molding part 60 for forming the inner diameter of each ring AR is not replaced, and the first molding part 50 for forming the outer diameter of each ring AR is replaced with one having the required outer diameter size. this is possible That is, the inner diameter portion 51 of the first molded part 50 may be replaced with a first molded part 50 having a different size.

In addition, since it is possible to mount and use the first and second molding parts 50 and 60 having different sizes in one molding device, that is, one mold, various types of angular rings (AR) can be formed in one mold. Since mass production is possible, the operation efficiency of the molding equipment can be increased.

In addition, the angular ring (AR) produced by the molding apparatus according to the present invention is not only the standardized angular ring (AR), but also the angular ring (AR) of a size that requires special production in addition to the standard product, the first molding part (50) corresponding to the size. ) And / or replacement with the second molding part 60, or in that it can be manufactured through a combination, it is possible to diversify the product variety through the provision of customized products. This is because a separate mold must be manufactured in the existing mold, which not only costs money to manufacture the mold, but also causes losses such as having to discard the mold if there is no order for an AR ring of the same size after the mold is manufactured. There is a downside to increasing efficiency.

As such, the present invention has been described with reference to one embodiment shown in the drawings, but this is only exemplary, and those skilled in the art can make various modifications and equivalent other embodiments therefrom. will understand
