The supporting frame for the roadside protection lid according to the present invention can be assembled and used as a whole in a round shape, a semi-circle shape, a square shape, a rectangle shape, a triangle shape, an H shape, a B shape, a C shape and the like.

Step 1: Basic mold-making process

In the present invention, in order to form the support frame for the roadside protection lid, first, a shape-shaped mold to be manufactured using wood is manufactured.

The basic wooden mold to be manufactured in this process is to manufacture a basic mold for manufacturing a metal mold.

Also, the basic wooden mold manufactured in this process is made of a mold having upper and lower ends.

The basic wooden mold to be manufactured at this time is to make a metal mold for forming a support frame for a roadside protection cover made of casting, and to mold a vertical base wooden mold having a pattern on the surface if necessary.

Step 2: Metal mold making step

At this time, the upper and lower molds of the basic wooden mold are made as thick as the metal mold to be made, and then the casting metal is poured at the upper part to produce a metal mold.

The metal used may be cast iron or a non-ferrous metal.

The metal mold manufactured in this process can be manufactured to have a pattern on the surface or can be made of a metal mold having no pattern.

That is, the pattern formed on the surface of the metal mold can be selectively formed according to the product to be produced.

In the present invention, metal molds are manufactured in the form of metal molds and used in the manufacture of molds for molds in order to solve the problem of repeatedly producing new molds due to worn edges or the like in the process of using and making wooden molds repeatedly.

Step 3: Fabrication of die casting mold using metal mold

The upper and lower molds are manufactured using the metal molds produced in the second step.

In this process, the sand used to make sand molds is a mixture of sea sand and tidal flats.

The sand mold mold is formed by compaction while spraying mixed salt water at a weight ratio of water 70: salt 30 to mud flat sand having a sand content of 50% to 90%.

In this case, the mold is formed so as to be formed as a single upper and lower molds. First, the tidal flats and sand are placed in the lower mold, the brine is sprayed, the metal mold made in the second process is placed on the sand embedded in the lower mold, Sprinkle with sand.

At this time, the salt water that is sprinkled on the sand only needs to be moistened with wet sand.

After the metal mold is installed on the lower mold as described above, the upper mold is filled with the sand in the same manner and the brine is sprayed, and the lower mold and the upper mold are laminated so as to face each other. Then, holes are formed from the upper part to the lower part, After the pipe is installed to form the molten metal injection hole to be connected to the metal mold tip, the sand is gathered from the upper part.

At this time, the compaction firmly compiles the tidal flat sand so that the demolition does not break off from the next formwork.

After the sand contained in the upper and lower molds is sandwiched as above, the upper and lower molds are separated in a state in which sand is contained, and then the metal mold located in the lower mold sand is released.

At this time, even if the metal mold is released in the lower mold sand, the shape in which the metal mold is located is maintained.

In addition, the upper and lower dies described in the present invention refer to a mold for sanding and compaction in order to make a sand mold.

Fourth step: Molding step of supporting tree support

In the state where the upper and lower molds formed in the third step are coupled, the prepared molten metal is filled through a molten metal injection hole formed on the upper mold in the upper mold.

At this time, the injection of molten metal is stopped when the molten metal is seen in the upper part of the molten metal injection hole.

After the molten metal is injected into the mold 4 as described above, the mold is cooled for 5 to 40 minutes, and then the upper and lower molds are separated. The molten metal is injected into the metal mold of the lower mold 4 to be cooled.

The thickness of the product to be molded may vary depending on the thickness and the size of the product to be cooled for 5 to 40 minutes after the injection of the molten metal. However, in the support plate for a roadside protection cover according to the present invention, The cooling time is determined in consideration of the size of the support frame for the roadside protection cover according to the present invention because the support frame is formed in such a way that the small single unit is cooled for 5 minutes and the large unit is cooled for 40 minutes.

After cooling as described above, the shaped support frame for the side protection cover is demolded.

Step 5: Polishing and painting steps

And the outer surface of the support frame for the roadside protection lid demolded from the mold die is processed.

Since the support frame for the roadside protection lid formed in the mold die is roughly formed on the outer surface and the mold rice is formed, the surface of the support frame is processed.

 Also, in order to install the pedestal for the roadside protection cover, the surface of the pedestal for the roadside protection cover is evenly polished so that painting can be done at this time by painting to harmonize with the surrounding color.

The processed pedestal for protecting the roadside protection lid has a ultraviolet shielding, corrosion prevention and durability by forming a pedestal frame so that a desired color can be expressed by painting.

The support frame for a side protection cover according to the present invention can be formed into a desired shape and pattern by casting molding, and since it is made of metal after installation, it can be used for a long time by minimizing wear, .
