Description

Mold for reclaimed rubber products of waste tire granules or chips}

The present invention is a recycled rubber molded product which is used as various mats and blocks that express numbers, letters, patterns, patterns, characters, etc. on the surface of the product by pulverizing finely generated waste tires and pressing the crushed chip or powder. The present invention relates to a regenerated rubber molded article molding mold capable of forming a die, and in particular, by separately forming a design mold capable of realizing various shapes by bending thin plates such as metal plates and plastics, to produce regenerated rubber molded articles containing various shapes. It is a molding mold for recycled rubber molded products that can greatly reduce mold cost.

In recent years, with the radical development of the automobile industry, the amount of waste tires used in automobiles has increased dramatically, while the recycling rate of waste tires is very small, so the problem of disposal of waste tires is the recycling of resources and environmental preservation. It is emerging as a problem that needs to be solved as soon as possible.

Unlike other wastes, these waste tires do not require special collection and sorting processes, so they are of great value as a recycling industry. However, in Korea, only a few treatment facilities are in practical use due to the constraints such as economic feasibility and marketability. The problem is deepening into social problems.

Therefore, by using a separate grinder to crush the above-mentioned waste tires into fine powder, mix the crushed chip or powder with a binder, fill it into a molding apparatus, and press-mold it, thereby regenerating rubber molded articles such as blocks and flooring materials for various facilities. It will be used to manufacture.

That is, as shown in Fig. 1, Fig. 2a to 2c, the upper mold 101, which is moved up and down by the cylinder 100, and the upper mold 101 is placed in the middle of the frame-shaped mold to press the filling inside ( 102 and a lower mold 104 having an embossed portion 103 which is pressed by the intermediate mold 102 and allows various shapes and patterns to be formed on the bottom surface.

The waste tire crushing chip or powder is mixed and filled with the binder in the inner space of the lower mold 104 and the intermediate mold 102 placed thereon, and then the waste tire crushing chip or powder inside the intermediate mold by the upper mold 101. When pressurized heating, the recycled rubber molded article 105 in which waste tire crushed chips or powders are compressed and bonded by a binder is primarily completed.

Then, as shown in FIG. 2B, the regenerated rubber molded product is turned over so that the groove 106 formed as the embossed portion 103 of the lower mold is positioned upwards, and then the colored layer material (waste tire powder + binder + pigment or synthetic rubber) is placed in the groove. Powder or urethane powder, etc.) 107 is selectively added, and then the final finished product is manufactured by pressurizing and heating again to the upper mold 101 as shown in FIG. 2C.

However, while the mold of the recycled rubber molded article using waste tires as described above is required to have a lower mold having an embossed portion, the embossed portion of the lower mold is always produced only in a constant shape, so that a recycled rubber molded article having various letters and patterns is produced. In order to produce a large number of lower molds with different embossed parts, it is necessary to replace the lower mold every time according to the increase in the cost of recycled rubber molded products due to the excessive demand of the mold cost and the type of recycled rubber molded products to be manufactured. Hassle to install.

In addition, after the first production of the regenerated rubber molded article shaped by the embossed portion of the lower mold, the rubber molded product is turned upside down, filling the material of the colored layer into the exposed grooves, and then pressing the product again to perform the final finished product. As a result, a process for producing a recycled rubber molded article rises, and a problem of low productivity is exposed.

Therefore, the present invention is devised to eliminate the problems as described above, by forming a pattern frame on the bending plate inside the frame and to form a separate design frame formed by connecting the pattern frame and the frame by a fixed support, The design frame is intended to increase productivity by enabling the production of recycled rubber molded articles expressing various numbers, letters, patterns, patterns, characters, etc. in one press operation.

In addition, the present invention is very simple and easy to produce a design frame, not only can produce a variety of reproduction rubber molded articles representing a variety of numbers, letters, patterns, patterns, characters, etc., but also without the use of separate machines and equipment It is an object of the present invention to provide a recycled rubber molded product mold using waste tire crushing chips or powder that can produce a variety of and rapidly recycled rubber molded products without any burden of mold cost because the mold can be produced directly in the mold.
