Description

Road sign bottle manufacturing method

The present invention relates to a method of manufacturing a road sign bottle, and more particularly, to a method of manufacturing a road sign bottle by performing a drawing operation with a high-pressure power press.

In general, road sign bottles are installed where there is a need to supplement the functions of road marking, such as the road's center line, lane border line, dedicated lane, road obstacles, and safety zones. Moreover, road sign bottles are not recommended to be installed at points where there is a risk of harming safe driving due to the installation of sign bottles such as pedestrian crossings and intersection stop lines.

As a conventional method of manufacturing a road sign bottle, there are precision casting, aluminum die casting, plastic injection, sand casting, glass melting press.

Precision casting is a casting method with higher dimensional accuracy than sand mold, mold, and die casting. The lost wax process, which industrialized the method of lead casting, the carbon dioxide method using carbon dioxide, and the show casting method using a special refractory mold (show) process). Precision casting has the disadvantage that toughness and malleability are significantly reduced.

Aluminum die casting is a casting method that melts the metal as a material in a metal mold mold called die, and forcibly pushes it under high pressure. Aluminum die casting is not suitable for small-scale production because the manufacturing cost of equipment and die is high. Due to the heat-resistant strength of the die, there is a disadvantage that the material is limited to non-ferrous metals such as aluminum, zinc, and tin having a low melting point.

Plastic injection is a plastic resin that is heated and injected into the cavity of a closed mold while heating the plastic resin while cooling in the mold to produce a molded product corresponding to the mold cavity, and thermoplastic resin is used for injection molding. . Plastic injection has the disadvantages of high mold prices, high cost of molding machines and auxiliary equipment, the inability to quickly determine the quality of molded products, and the inability to accurately control the injection molding process.

Sand casting is a method of making a casting using the sand casting mold. It is made by casting sand, clay, or water into a molding made of wood, plaster, or metal. It's rough.

Press the glass-melting press to engrave the desired mold with a metal frame, cut the glass into it, and press it with the metal frame of the central mold called me to complete it. Pressurized glass melting press can be easily fragile glass due to warping in the process.

As a prior art related to the present invention, Patent Document 1 is a method for manufacturing a road sign bottle mounted on a road and used to guide a road to a driver and a pedestrian, preparing a mold having an upper open hollow space in the shape of a road sign bottle therein To do; Forming a phosphorescent layer by first curing a compound containing a transparent resin, a phosphorescent pigment, and a curing agent in the central phosphorescent surface of the mold; Integrating the phosphor layer and the body portion by secondly injecting and curing a compound containing a resin, stone powder, coloring pigment, and curing agent on top of the phosphor layer; Separating and separating the photoluminescent layer and the body from the mold; Attaching opposing ultra-high-brightness reflectors to each of the two inclined surfaces and the right-angled surfaces of the body where the photoluminescent layer is formed; Injecting a coating solution of a compound containing a transparent resin, UV blocking agent, curing agent into the mold for a third time; A step of coating the entire surface of the photoluminescent layer, the ultra-high-brightness reflective paper, and the body part by forming a coating layer by filling the body with a phosphorescent layer and an ultra-high-brightness reflective paper as the coating solution in the mold; And after the coating layer is cured, separating the body portion, the reflective paper, the photoluminescent layer, and the coating layer from the mold to complete a road sign bottle product; including, the photoluminescent layer, the body portion and the coating layer using the same component resin Thus, a method of manufacturing a road sign bottle is disclosed by forming an integrally cured material to achieve integration between mutual components, preventing separation or peeling between parts, and increasing strength.
