Description

Mold for a boundary stone

The present invention relates to a boundary stone manufacturing template.

In general, the boundary stone installed between the driveway and the sidewalk is conventionally manufactured by simply using a formwork, so the density and strength are weak. As a result of continuous impacts such as rain and rain, aging gradually increased, resulting in a breakage or rough surface. In addition, the economic loss of labor costs, material costs, environmental waste disposal costs, as well as traffic congestion caused re-construction, was subject to complaints.

Therefore, in order to solve the problems of the conventional boundary stone, a centrifugal molding apparatus for producing boundary stones using centrifugal force has been recently developed, and in particular, it is proposed in the publication of Korean Utility Model Registration No. 20-0329393. According to this publication, the opening face is laid in a 'c' shape, with the hole facing upward, the body having holes formed in the upper center of the left and right pillars respectively, and perpendicular to the center of the plate-shaped circular low ring and the circular low ring. Each of the rods extending from the first and second rotors and concrete mortars are inserted to be rotatably inserted into the holes of the left and right pillars of the body in a state in which each circular row ring is positioned to face the inside of the body. As a rectangular frame to be filled, a circular row ring having the same shape as the circular row ring of the first and second rotating bodies is mounted on both sides, so that the first and second rotating bodies are located in a circular state. It is composed of a boundary stone manufacturing mold that is bolted to the low ring and a motor coupled to the rod of the first rotating body in a chain manner to rotate the first rotating body at high speed.

The manufacturing mold is a boundary-shaped frame with an upper opening, two inner frames filled with concrete mortar, an outer frame for receiving and fixing two inner frames with an upper portion open, and a bolt connected to an upper portion of the outer frame. It consists of a cover covering the frame.

However, there are the following problems of the boundary stone manufacturing mold of the above-described configuration.

The cover covering the upper surface of the manufacturing mold is fastened and fastened with a plurality of bolts, and thus, the worker is inconvenient and the manufacturing process time increases because the bolts must be fastened or separated one by one.

In addition, two manufacturing molds are arranged in the longitudinal direction, and the boundary stone manufactured by the manufacturing mold is hollowed out by centrifugal force. At this time, the strength of a specific portion is weakened, and deformation or wear may be intensified.

The present invention has been made to solve the above-described problems, and since both sides of the manufacturing mold can be opened or closed by the side plate, it can be easily demolded when demolding the boundary stone, fixed without fastening by fastening means one by one Since the side plate can be fixed by rotating the means in a one-touch form, the operator can quickly and conveniently perform the assembly and demoulding operation is to provide a boundary stone manufacturing template that can reduce the manufacturing process time.

Another feature of the present invention is to provide a boundary stone manufacturing template in which the hollow is formed in a semicircular shape at the edge of the boundary stone, and the thickness from the hollow to the edge becomes thicker, so that deformation and abrasion do not easily occur.

The boundary stone manufacturing mold of the present invention for achieving the above object is a mold portion filled with a concrete mortar inside and the upper and both sides open; Side plates for opening and closing both sides of the mold; A cover covering the open upper surface of the mold part; It comprises a fixing plate disposed at intervals with the side plate, is provided with a fixing means for fixing the side plate.

According to this structure, since both sides of the manufacturing die can be opened or closed by the side plate, it can be easily demolded when demolishing the boundary stone, and the side plate is fixed by rotating in the width direction of the manufacturing die, Even if the fixing plate is fixed to both sides, the worker can easily work.

In the above-described configuration, the fixing means includes a rotating part disposed in a plane forming a width direction and a vertical direction of the manufacturing die between the side plate and the fixing plate, and a pressing part for pressing the side plate when the rotating part is rotated. It is done by

In this case, since it is possible to fix the fixing means in one-touch form without fastening by fastening means one by one, it is possible to shorten the manufacturing process time because the operator can quickly and conveniently perform the assembly and demoulding work.

On the other hand, according to another configuration of the fixing means for achieving the above object, the fixing means is a rotating portion disposed in the plane forming the width direction and the vertical direction of the mold between the side plate and the fixing plate, and the rotating part Rotating is made of a pressing portion for pressing the side plate, a gripping portion extending to one end of the pressing portion, and formed in the manufacturing flat, the clasp for holding the holding portion.

As such, when the lower frame 173 is moved, the rotating shaft through hole 471 of the manufacturing mold 400 fixing plate 470 is fitted to the first rotating shaft 250a, and the two protrusions 710 of the fixing plate 470 are Respective sides of the side pressing portion 730 of the side pressing portion 730 are supported.

Then, by operating a button, as shown in Fig. 7b, the second column 150 is moved to the side where the manufacturing mold 400 is arranged.

When the second column 150 is moved in this way, the second rotating shaft 250b is fitted into the rotating shaft through hole 471 of the fixing plate 470 opposite to the manufacturing mold 400, and two protrusions 710 of the fixing plate 470 are inserted. ) Is supported at each side of the side pressing portion 730 of the side pressing portion 730 of the second rotating plate (210b).

Thereafter, the button is operated to move the upper frame 171 of the vertical movement means 175 downward as shown in FIG. 7C.

When the upper frame 171 is moved downward and the motor 310 is driven, the plurality of pulleys 350 arranged in parallel by the belt 330 are rotated at the same time and the plurality of first rotating bodies 200a are rotated. Rotate at the same time.

As a result, the manufacturing mold 400 is rotated, and the second rotating body 200b at the other end of the manufacturing mold 400 is also rotated.

When the motor 310 is stopped after a certain time has elapsed, the rotation of the manufacturing mold 400 is stopped, and a button is operated in the reverse direction to move the upper frame 171 upward, and the second pillar 150 is moved. The fixing plate 470 and the second rotating plate 210b of the manufacturing mold 400 are moved in a direction in which the second plate is separated (the right direction in FIG. 7B) to separate the fixing plate 470 and the second rotating plate 210b, and then the lower frame 173 is removed. Moving to the second rotating body 200b side (right direction in FIG. 7A), the fixed plate 470 and the first rotating plate 210a are separated from each other.

Thereafter, as shown in FIG. 10, the manufacturing mold 400 can be transferred to the elevating device 20 through a conveying device 10 such as a rail.

The lifting device 20 may elevate the manufacturing mold 400 by applying the hydraulic piston 21 method similarly to the lifting frame 170 described above.

By the lifting device 20, the manufacturing mold 400 may be transferred to a loading table 30 provided with a plurality of compartments, and then, may be transferred to a curing chamber for curing work.

After completion of the curing operation, the operator opens the cover 490 of the manufacturing mold 400, separates both side plates 430, and demolds the boundary stone 900.

In this way, as shown in FIG. 11, two boundary stones 900 can be obtained per manufacturing mold 400.

At this time, the hollow 910 is formed inside the boundary stone 900 by the centrifugal force. Since the hollow 910 is formed at the center of the mold 410, two boundary stones 900 are formed in semicircular shapes. As such, when the hollow 910 is formed in a semicircular shape at the edge of the boundary stone 900, the thickness from the hollow 910 to the edge becomes thicker, and deformation and wear do not easily occur.

In this way, the manufacturing mold 400 filled with concrete mortar is rotated by the driving means 300 to centrifugally shape the boundary stone 900, not only to obtain a smooth surface of the boundary stone 900, but also to increase the density. The boundary stone 900 excellent in durability and strength can be produced in large quantities.

In addition, since the first and second rotary bodies 200a and 200b are formed in plural and arranged in parallel, the first and second rotary bodies 200a and 200b are rotated at the same speed at the same time. The boundary stone produced through the manufacturing mold rotated by (200a, 200b) may have a constant density.

In addition, the lifting frame 170 is provided to be movable up and down, and at the same time, it is formed to be movable left and right, thereby automatically coupling and separating the manufacturing mold 400 to the first and second rotating bodies (200a, 200b). It can be done quickly and efficiently.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications of the present invention without departing from the spirit and scope of the invention described in the claims below. Or it may be modified.

According to the boundary stone manufacturing mold of the present invention as described above, there are the following effects.

Since both sides of the mold can be opened or closed by the side plate, it can be easily demolded when the boundary stone is demolded, and the fixing plate is fixed to both sides of the mold by rotating in the width direction of the mold. Even if it is, the worker can easily work.

Furthermore, by providing a fixing means for pressing and fixing the side plate, it is possible to fix the fixing means in one-touch form without fastening by fastening means, so that the operator can quickly and conveniently perform the assembly and demoulding work. The manufacturing process time can be shortened.

On the other hand, by fixing the cover by the cover fixing means, it can be fixed in one-touch type without fastening the fastening means such as bolts one by one, the operator's convenience is increased, and assembling and demolding work can be performed quickly and conveniently, manufacturing process It can save time.

In addition, since the water discharge hole is formed in the center of the side plate, when the manufacturing mold is rotated during the manufacture of the boundary stone, the moisture of the concrete mortar escapes through the water discharge hole, and the hollow edge generated by the centrifugal force is smoothed in the center of the boundary stone. There is no need for a post-treatment step to smooth the hollows.

Furthermore, since the form part is composed of two and coupled in parallel to each other, since the hollow is formed in a semicircular shape at the edge of the boundary stone, the thickness from the hollow to the edge becomes thicker, so deformation and wear do not easily occur.
