Fig. 14A is a schematic view of a sidewalk block forming apparatus according to the prior art document 2 (Korean Patent Registration No. 1110163), Fig. 14B is an enlarged view of a drain hole forming pin applied to a sidewalk block forming apparatus according to the prior art document 2 And FIG. 14C is a cross-sectional view showing a sidewalk block molding process using the sidewalk block forming apparatus according to the prior art document 2.

In the press block forming apparatus according to the prior art document 2, when the conveying plate 30 is conveyed to the upper side of the bottom plate 20, the forming frame 10 is lowered and brought into close contact with the conveying plate 30. At this time, when the bottom plate 20 is raised by the plate cylinder 21, the fin 23 is superposed on the feed plate 30 and protruded into the pin hole 31 to enter the mold frame 10. In this state, when the base layer mortar input base 42 is positioned in the molding die 10, the base layer mortar 51 is inserted into the molding die 10.

Subsequently, vibration is applied to the forming die 10 to consolidate the base layer mortar 51, and high pressure air is supplied from the air hose 26 of the bottom plate 20 to the air inlet chamber 22, High-pressure air is injected into the air nozzle 25. Since the upper end of the pin 23 is initially embedded in the base layer mortar 51, when the high-pressure air is injected from the air nozzle 25, the upper portion of the base layer mortar 51 is spread out to be formed as the pin 23 A drainage guide groove 54 communicating with the drainage hole 53 is made in the sidewalk block 50.

Then, the fine-grained layer mortar input base 43 is placed on the upper side of the forming die 10, and the fine-grained layer mortar 52 is inserted into the upper portion of the base layer mortar 51, The press plate 40 of the fine layer mortar 52 is lowered to press the upper portion of the fine layer mortar 52 to bind the fine layer mortar 52 and the base layer mortar 51 and then to rise.

Next, the bottom plate 20 is lowered, the pin 23 is separated from the forming die 10, the press plate 40 is lowered again, and the forming die 10 is raised in a state where the fine dry mortar 52 is pressed When it is separated from the mortar, the press block 50 is placed on the conveying plate 30, and then the press plate 40 is finally lifted up and separated.

Since only the completed sidewalk block 50 is left in the conveying plate 30, when one conveying plate 30 is conveyed to the drying area, one sidewalk block is completed. When the above process is repeated continuously, The sidewall 53 and the drainage guide groove 54 can be formed.

The core technology of the sidewalk block forming apparatus of the prior art document 2 is that the drain hole 53 and the drain guide groove 54 are formed in the base layer mortar 51 and at the same time the finished sidewall block 50 ).

However, the press block 50 as described above has a limit in that it can not smoothly realize the drainage of the rainwater because the fine mortar 52 is formed on the drain hole 53 and the drain guide groove 54.

That is, the time required for the rainwater to penetrate into the fine mortar 52 is long, and the drainage to the induction groove 54 and the drain hole 53 is not smooth.

The sidewalk block forming apparatus of the prior art document 2 is not structured to form the drain hole 53 and the drain guide groove 54 in a structure in which the pin 23 and the press plate 40 are in direct contact with each other.

That is, when the pin 23 and the pressure plate 40 are in direct contact with each other, if foreign matter is caught between the pin 23 and the press plate 40, the pin 23 is easily The pin 23 and the pressing plate 40 are not in direct contact with each other.

For this reason, in the prior art document 2, high pressure air is sprayed from the air nozzle 25 while the upper end of the pin 23 is buried in the foundation layer mortar 51, and the drain guide groove 54 Pressure jet air generated by the air nozzle 25 is blown out by blowing a part of the base layer mortar 51 to form the drainage induction groove 54 The fine layer mortar 52 is put on the fin layer mortar 52 so that the pin 23 does not directly come into contact with the press plate 40 and is pressed onto the press plate 40, It is not possible to provide a vertical drain hole at all.

[

That is, the turntable T is rotated between the upper body B1 and the underbody B2 in accordance with the step-by-step rotation of the center motor M by the dry-type mortar supply unit 100, the dry-type compaction unit 200, 300, a wet planarization unit 400, a powder coating dropping unit 500 (FIG. So that the lower molds 80 can be positively positioned while being sequentially rotated toward the mortar crimping portion 600 and the sidewalk block releasing portion 700. The lower powder mold dropping portion 500a and the post- .

Specifically, when the lower mold 80 is properly positioned in the dry mortar supply part 100, for example, the particles containing a small amount of water are composed of small gravel, sand and cement (composition and composition ratio are general matters, The dry mortar 91 is filled in the lower mold 80 and moved to the dry compaction unit 200. When the lower mold 80 is properly positioned in the wet mortar supply unit 300, Sand, and cement containing a sufficient amount of water (the composition and composition ratio are general matters, so that a detailed description thereof is omitted), and the wet mortar 92 in a kneaded state having a color is filled on the dry mortar 91, When the lower mold 80 is properly positioned in the wet-type planarization unit 400, the wet-type mortar 92 is planarized, and then the powder coating dropping unit 500 (FIG. The powder coating material 94 is dropped through the linear powder coating fall portion 500a and the posterior powder coating falling portion 500b so as to have various kinds of calatons and further the wet mortar 92 is again supplied from the mortar pressing portion 600 And the moisture is introduced into the dry mortar 91 to be dewatered to provide a sidewalk block 90 which is firmly pressed against each other. Then, the sidewalk block is deformed through the sidewalk block defor- mation part 700 to be dried and cured Thereby completing the rigidly reinforced paving block 90.

The lower mold 80 for a press block manufacturing apparatus according to the present invention has a lower opening 81a as shown in FIGS. 1 to 3B and a lower mold 80 for defining a shape of a side surface 90c of the press block 90, A flow base 83 which is spaced apart from the lower end of the lower mold 81 by spacing means 82 and which covers the lower opening 81a while having an internal through hole 83a, And a lower pinhole 85a which is seated in the flow base 83 in the lower mold 81 and through which the pins 84 are passed, And a bottom plate 85 for determining the shape of the bottom surface 90b.

For example, the lower mold 81 has a structure that determines the shape of the side surface 90c of the press block 90 such as a square, a rectangle, a polygon, or an ellipse, and is formed in the mold holes T1 of the turntable T And the flow base 83 covers the lower opening 81a so as to be separated from the lower end of the lower mold 81 by the spacing means 82. [

At this time, the flow base 83 normally abuts against the lower end of the lower mold 81 to closely cover the lower opening 81a, but the force of physically lowering to the flow base 83 The inner through hole 83a is configured to be separated from the lower end of the lower mold 81 by the spacing means 82 as shown in Fig. 3b (arrow) The presser bundle 61e of the pressurized hydraulic means 61 is passed through the lower plate 85 and the reinforcing plate 86 so that the lower plate 85 and the reinforcing plate 86 can be pushed up.

More specifically, the spacing means 82 is sequentially pierced from the edge of the flow base 83 toward the screw groove 82a of the lower mold 81, with the screw groove 82a bored in the lower end of the lower mold 81, A toroidal step 82d provided by the advancing optical hole 82b and the narrowing hole 82c and an extension spring 82e sandwiched by the hole 82b to be supported by the toroidal stepped portion 82d, And a spacing bolt 82f fastened to the screw groove 82a of the lower mold 81 via the narrow hole 82c while being pressed against the toroidal stepped portion 82d.

The spacing bolt 82f is fastened to the threaded groove 82a via the narrow hole 82c while pressing the extension spring 82e fitted into the optical hole 82b to the toroidal stepped portion 82d, The action of the extended spring 82e supported and the reaction can tightly cover the lower opening 81a by allowing the flow base 83 to be brought into close contact with the lower end of the lower mold 81 as shown in FIG. The donut-shaped step 82d contracts the extension spring 82e and moves from the lower end of the lower mold 81 to the flow base 83 as shown in FIG. 3B, .

A lower mold 80 for a press block manufacturing apparatus according to the present invention includes a reinforcing plate 86 interposed between the flow base 83 and the lower plate 85 and having reinforcing pinholes 86a through which the pins 84 are passed, And further includes liners 87 detachably fastened to the inside of the lower mold 81 so as to be relatively higher than the height of the lower mold 81. [

When the dry mortar 91 and the wet mortar 92 filled in the lower mold 80 are continuously pressed in the mortar compression part 600, the phenomenon that the lower plate 85 is deformed by the compression pressure is applied to the reinforcing plate 86 When the upper mold 62 directly contacts the lower mold 80 when the dry mortar 91 and the wet mortar supply unit 300 are pressed against each other, the lower mold 80 is deformed The replacement liner [87; The liner 87 made of the heat-treated alloy] is detachably fixed to the inside of the lower mold frame 81 relatively higher than the height of the lower mold frame 81 to ensure a service life.

Preferably, the liner (87) is fitted in a fixing groove (83c) formed along the edge of the flow base (83).

When the liner 87 is fitted in the fixing groove 83c formed along the edge of the flow base 83 to apply a force to physically lower the flow base 83, the liner 87 fitted in the fixing groove 83c And the leakage of the dry mortar 91 can be prevented (when the flow base 83 has a structure that simply covers the lower opening 81a of the lower mold 81, Not only the dry mortar 91 but also the upward flow of the flow base 83 can be prevented from being continuously released due to the foreign matter caught in the gap therebetween. .

Then, the pin 84 is screwed into the screw hole 83d drilled in the flow base 83 so as to be vertically adjustable.

The press block 90 may have a different height depending on the construction environment so that a pin 84 is formed in the screw hole 83d drilled in the flow base 83 in accordance with the height of the vertical drain hole 97 To be vertically and horizontally adjustable so as to more effectively manufacture the sidewalk blocks 90 of various sizes.

4A is a perspective view showing a sidewalk block 90 provided by applying a lower mold 80 for a sidewalk block manufacturing apparatus according to the present invention, and Fig. 4B is a perspective view showing a bottom mold 80 for a sidewalk block manufacturing apparatus according to the present invention And FIG. 4C is a plan view showing a press block 90 provided by applying a lower mold 80 for a press block manufacturing apparatus according to the present invention.

As a great feature of the lower mold 80 for a press block manufacturing apparatus according to the present invention, the pin 84 is fixed to the flow base 83 at the same height as the liner 87.

The press block 90 so far includes a vertical half drain hole 95 formed at the edge thereof to form a drainage passage so as to be combined with the vertical half drain hole 95 of the neighboring press block 90, ) Is completed.

The vertical half drain hole 95 at the edge of the sidewalk block 90 can be easily formed by the embossing of the liner 87 for example but the vertical drain hole 97 in the sidewalk block 90 is formed by the pin 84 and the upper The pin 84 is prevented from being damaged by the confronting pressure between the lower mold 80 and the upper mold 62 even if the pin 84 has a small foreign substance on the pin 84. [ There is a case in which the vertical drain hole 97 can not be easily broken.

Such a reality is easily confirmed by looking at the height of the fin 23 which is drilled in the drain hole 53 (strictly drain hole) only to the foundation mortar 51 as in the prior art document 2 and which can not penetrate the fine mortar 52 .

In the present invention, even when a force is applied to the flow base 83 so that foreign matter is caught on the pin 84 while the pin 84 is fixed to the flow base 83 at the same height as the height of the liner 87, It is possible to protect the pin 84 by separating the flow base 83 from the lower end of the lower mold 81 by means of the separating means 82 prior to the breaking of the pin 84, So that we can eliminate it.

Accordingly, the press block 90 according to the present invention includes a top surface 90a, a bottom surface 90b and a side surface 90c as shown in Figs. 4a to 4c, And further includes a concave drain groove 98 formed concavely in the top surface 90a in the vicinity of the vertical drain hole 97. The vertical drain hole 97 is formed in the upper surface 90a, .

When the area of the sidewalk block 90 is wide, the vertical drain hole 97 of the sidewalk block 90 as well as the siphon drain hole 96 draining the rainwater as a combination with the neighboring sidewalk block 90 at the edge, The drainage of the rainwater in the vertical drainage hole 97 can be quickly realized along the concave drainage groove 98 to facilitate drainage such as delivery or sidewalk during the rainy season, And to positively prevent the inconvenience caused by the overwork and the risk of freezing in winter.

Further, it is preferable to further include a top drainage path 99 leading to the vertical drainage hole 97 along the top surface 90a so as to realize rapid drainage in the event of an excellent drainage.

At this time, in the structure of the mortar press portion 600, the upper mold 62 is provided with the convex projection 62a toward the pin 84 of the lower mold 80, while the pin 84 is provided on the convex portion 62a When the convex projection 62a abuts on the pin 84 in a state where the convex projection 62a is erected on the flow base 83 lower than the height of the liner 87 by the height of the liner 87, It is possible to protect the pin 84 while separating the flow base 83 from the lower end of the lower mold 81 by the separating means 82 so that the press by the convex projection 62a of the upper mold 62 The concave drain groove 98 of the block 90 can be more easily provided.

A process of manufacturing the press block 90 by applying the lower mold for a press block manufacturing apparatus according to the present invention will now be described.
