Therefore, the shape of the forming groove 111 may be formed in the shape of the upper opening is formed in the pattern (pattern) of the various grid structure (Grid) according to the design shape of the mesh fence 10 to be molded. However, in order to maximize the mechanical properties of the mesh fence 10, it is preferable that the string forming space portion 111a and the blade forming space portion 111b are formed to cross each other.

In addition, the meaning of the string and the string in the string molding space portion (111a) and the blade molding space portion (111b) does not necessarily have the meaning of horizontal (horizontal) and vertical (vertical) in the functional description of the mutually relative arrangement position Referring to (a) of FIG. 10 as a term, the seed molding space part 111a and the blade molding space part 111b may be formed to cross each other in a diagonal direction.

In addition, in forming the forming groove 111 in the upper portion of the mold frame 110, by milling the plate-like plate material (milling) comprises the seed forming space portion 111a and the blade forming space portion 111b. Forming groove 111 may be formed, but when forming a high-strength metal so as not to be worn and deformed while performing repeated molding operations, by shaping the shape of the precise forming groove 111 through the milling process. Since the bet may be limited, as illustrated in FIG. 1, a plurality of shape frames 113 capable of forming the shape of the molding groove 111 are disposed on the flat base frame 115 and the base frame is disposed. The forming groove 111 may be formed on the mold frame 110 by forming the side frame 114 covering the outer portion around the 115.

In addition, a plurality of pressing pin holes 112 through which the pressing pins 141 of the mesh fence removing unit 140 may be inserted are formed at the bottom of the forming groove 111, and the pressing pins 141 may include molding grooves ( It is used to press the mesh fence 10, which has been cured, in the state in which the reinforcing fibers 121 are laminated on the base material composition 20 in the 111 to be removed in the forming groove 111. In addition, the pressing pin hole 112 is disposed at a position where the string forming space 111a and the blade forming space 111b cross each other in the forming groove 111, so that the pressing pin 141 is mesh fence 10. Pressing the intersecting portion of the) can prevent the deformation or twisting in the process of removing the mesh fence 10 in advance.

In addition, the pressing pin hole 112 is formed to have an inner diameter corresponding to the size of the outer diameter of the pressing pin 141, the base material composition 20 injected into the molding groove 111 through the pressing pin hole 112 is It is desirable to be provided so as not to leak.

On the other hand, the base material composition 20 is a main component constituting the mesh fence 10 according to a preferred embodiment of the present invention, is formed by stirring the base material and various additives. Thermosetting polymer resin (30-40%) is used as the base material, and various additives include reinforcing filler (30-40%), diluent (trace), low shrinkage additive (5-10%), and curing agent (3%). ), A polymerization inhibitor (Polymerzation In hibotor), a UV inhibitor (UV Inhnbotor), a pigment pigment (Pigment), an impact agent and a modifier may be added.

Herein, the thermoset polymers are materials which do not change in shape after being heated and cured, and are typically unsaturated poliester, vinyl ester, and epoxy. , Phenol (Phenol) and polyamide (Polyamide) can be used. Since the thermosetting polymer resin is included in the mesh fence 10, it does not soften or deform at high temperatures, does not easily break or crack even at low temperatures, and has excellent chemical resistance to corrosion and heat.

The reinforcing filler serves to improve the properties of the filling and reinforcement, to reduce the volume shrinkage of the thermosetting polymer resin and to increase the flow to improve the formability, and to improve the surface accuracy of the molded mesh fence 10 Let's do it. As the reinforcing filler, aluminum hydroxide (Alumina Trihydrate), magnesium hydroxide (Magnesium Hydroxide), calcium carbonate (Calcium Carbonate) and talc may be used depending on the desired physical properties of the mesh fence 10.

It promotes gelation and shortens curing time.

In addition, the reinforcing fibers 121 impregnated in the base material composition 20 are added to maximize the mechanical properties of the mesh fence 10, and include glass fibers, carbon fibers, and kevlar fibers. Kevlar Fiber, and Aramid Fiber can be used. In particular, the double glass fiber is a continuous fiber of strand roving, and is selectively used according to the desired physical properties such as E-Glass, Alkali Glass, Chemical Glass, Lead Glass, S-Glass, and M-Glass. Can be.

In addition, the mold mold 110 uses a mold made of steel for durability of the dimensional stability of the hardened mesh fence 10 and the permanent use of the mold mold 110, and is polished on its surface. It is preferable to form corrosion resistance and chemical resistance. In addition to the steel material, aluminum, stainless, duralumin, or the like may be used depending on the components of the base material composition 20 injected into the molding groove 111.

The reinforcing fiber supply unit 120, the reinforcing fibers 121 are cross-linked to the base material composition 20 injected into the molding groove 111 of the mold die 110 to discharge the reinforcing fibers 121 to be laminated in a plurality of layers. As a component, the base material composition 20 is disposed on the mold frame 110 and receives the reinforcing fiber 121 from the reinforcing fiber winding roll 122 in which the reinforcing fiber 121 is wound. Impregnated in the cross-shaped injection molding space portion 111a and the raw molding space portion 111b alternately in the form of a cross (Empregnation) is discharged so that the reinforcing fibers 121 are laminated in a plurality of layers in the base material composition (20).

More specifically, as shown in FIGS. 3 to 5, the reinforcing fiber supply unit 120 includes a through hole through which the reinforcing fibers 121 supplied from the reinforcing fiber winding roll 122 pass. The guide tube 124 is formed therein and disposed in the vertical direction toward the molding groove 111, and the fiber laminated guide is disposed on top of the mold frame 110, one or more guide tube 124 is fixedly mounted ( 123) is provided.

Here, the two guide tubes 124 are mounted on the fiber lamination guide 123, but the supply of the reinforcing fibers 121 to the blade forming space portion 111b in units of two lines, but is not limited thereto. The spacing distance of each guide tube 124 may be adjusted according to the spacing distance of each of the forming groove portion 111 and the string forming space portion 111a and the blade forming space portion 111b, respectively. Or three or more may be installed, a plurality of reinforcing fiber supply unit 120 having a different separation distance may be used.

In addition, between the reinforcing fiber supply unit 120 and the reinforcing fiber winding roll 122, the reinforcing fiber 121 supplied from the reinforcing fiber winding roll 122 is stably introduced into the reinforcing fiber supply unit 120 A guide pulley 125 may be disposed to support the movement of the 121. In addition, a single line of reinforcing fiber 121 may be introduced into one guide tube 124 as shown in FIG. 3, but a plurality of reinforcing as shown in FIG. 4 so that a plurality of rows of reinforcing fibers 121 may be stacked in a plurality of layers. The fiber winding rolls 122 are matched and arranged for each guide tube 124 and the plurality of lines of reinforcing fibers 121 supplied from each reinforcing fiber winding roll 122 are simultaneously introduced into one guide tube 124. The reinforcing fibers 121 may be stacked in a plurality of rows in the molding groove 111.

In addition, the reinforcing fiber supply unit 120 receives the reinforcing fiber 121 from the reinforcing fiber winding roll 122 as described above, the seedling forming space portion 111a and the raw molding space portion into which the base material composition 20 is injected. The reinforcing fibers 121 are alternately impregnated in a cross shape so that the reinforcing fibers 121 are stacked in a plurality of layers in the base material composition 20.

Here, in laminating a plurality of layers while alternately impregnating the reinforcing fibers 121 in the form of a cross, as shown in Figure 5, the reinforcing fiber supply unit 120 in the longitudinal direction (L) or at the top of the mold frame 110 While supplying the reinforcing fibers 121 to the molding groove 111 without stopping while moving in the width direction (W), in the first turn of any one of the blade forming space portion 111b and the line forming space portion (111a) The reinforcing fiber 121 is supplied to the molding space, and as shown, when the reinforcing fiber 121 is first supplied to the raw molding space 111b, the reinforcing fiber supply unit 120 is zigzag at the top of the mold mold 110. While moving in the manner to impregnate the reinforcing fibers 121 only in the blade forming space (111b).

Subsequently, in the second turn, the reinforcing fiber 121 is impregnated with the reinforcing fiber 121 only in the string forming space part 111a while moving in a zigzag manner to the string forming space part 111a in which the reinforcing fiber 121 is not impregnated. Impregnating the reinforcing fibers 121 in the same manner in the molding space 111b, and thus repeats the process of alternating impregnation of the reinforcing fibers 121 in the form of corose.

 At this time, at the position where the blade molding space portion 111b and the string molding space portion 111a cross each other, as described above, the reinforcing fibers impregnated in the blade molding space portion 111b and the string molding space portion 111a, respectively ( 121 are laminated while crossing each other, and as a result, as shown in FIG. 6, the reinforcing fibers 121 are arranged in a plurality of layers while being arranged in a cross shape inside the molded mesh fence 10. .

In addition, when the reinforcing fiber 121 is supplied into the forming groove 111 by the reinforcing fiber supply unit 120, it is preferable that about half of the filled state is injected into the forming groove 111. Do. This is because if the base material composition 20 is not injected into the molding groove 111 at all, when the reinforcing fiber 121 is laminated and then the base material composition 20 is injected, the laminated reinforcing fiber 121 is formed into the molding groove. When the reinforcing fiber 121 is laminated in the state filled with the base material composition 20 in the molding groove 111, the reinforcement fiber 121 is smoothly laminated to the base material composition 20. This is to prevent the phenomenon of being impregnated to the upper side of the forming groove 111 is not impregnated.

Therefore, before stacking the reinforcing fibers 121 in the molding groove 111, about half of the base material composition 20 is injected into the molding groove 111, and the base material composition injected into the molding groove 111 ( 20 is laminated on the reinforcing fibers 121 in a plurality of layers, and then uniformly stacked in the center of the mesh fence 10 formed by injecting the base material composition 20 of the remaining half of the forming groove 111. Reinforcing fibers 121 may be disposed.

The temperature control pipe part 130 is a pipe line mounted to be in contact with the lower portion of the mold frame 110, and receives the heated or cooled heating medium from the heating medium heating unit 137 or the heating medium cooling unit 138 to the inside. By selectively heating or cooling the mold die 110 while flowing, the base material composition 20 injected into the molding groove 111 is stably cured in a short time.

As shown in FIG. 7, the temperature control pipe part 130 is divided into the heat medium heating part 137 and the heat medium cooling part 138, respectively, to a heat medium circulation path 139a and 139b in which the heat medium is circulated. Connected.

Here, the heat medium may be representatively used as a fluid medium in which the temperature is changed by the heat medium heating part 137 and the heat medium cooling part 138. In addition, the material used as the fluid medium in the technical field to which the present invention pertains. You can apply any of these.

The heat medium heating unit 137 is configured to heat and discharge the heat medium flowing in such as a boiler, and the heat medium cooling unit 138 cools and discharges the heat medium flowing in such as a cooler or a cooling chiller.

Referring to FIG. 7, the heat medium discharged in a heated state through the heat medium heating part 137 is introduced into the temperature control pipe part 130 through the inlet 134 of the temperature control pipe part 130. While heating the inside of the temperature control pipe 130, the relatively low temperature control pipe 130 and the mold 110 in contact with the temperature control pipe 130 is heated.

The heat medium cooled by taking heat while heating the temperature control pipe 130 and the mold 110 is introduced into the heat medium heating unit 137 through the heat medium flow path 139a, and is heated again. It is discharged to the inlet 134 of the control pipe 130.

Here, a time cycle of 8 hours to 10 hours is required in the natural dry state at room temperature until the base material composition 20 and the reinforcing fiber 121 are chemically bonded to each other and cured. However, through the configuration in which the mold die 110 is heated by the temperature control pipe 130, it is possible to heat the base material composition 20 injected into the molding groove 111 of the mold die 110. The time cycle can be reduced to 15-25 minutes.

In addition, the temperature at which the mold die 110 is heated by the temperature control pipe 130 may not affect the mechanical and chemical properties of the base material composition 20 and the reinforcing fiber 121 injected into the molding groove 111. It is preferable to determine within 80 to 90 degree according to the kind of material of each structure.

In this way, by minimizing the curing time cycle as much as possible and molding at a temperature condition that does not affect the mechanical and chemical properties, it is possible to shorten the manufacturing production cycle to secure economic productivity.

On the other hand, the heat medium discharged in the cooled state through the heat medium cooling unit 138 is introduced into the temperature control pipe unit 130 through the inlet 134 of the temperature control pipe unit 130, the temperature control pipe While cooling the inside of the part 130, the relatively low temperature temperature control pipe part 130 and the mold die 110 in contact with the temperature control pipe part 130 are cooled.

In addition, the heat medium heated by cooling the temperature control pipe part 130 and the mold mold 110 is discharged through the outlet 136 of the temperature control pipe part 130, and the heat medium circulation path 139b is opened. Through the heat medium cooling unit 138 through the cooling is again discharged to the inlet 134 of the temperature control pipe 130.

Here, since the base material composition 20 and the reinforcing fiber 121 have different mutual thermal expansion coefficients, thermal stress occurs due to temperature, and a mesh fence generated when the mesh fence 10 is formed due to thermal expansion. Bending, twisting and distortion of the (10) and residual stress may occur, but the mold frame 110 is cooled by using the temperature control pipe 130 so that the mesh fence 10 as described above. It is possible to prevent deformation in advance) and to form the mesh fence 10 stably.

In addition, the temperature control pipe 130 is disposed so as to be in surface contact with the mold mold 110 so that the thermal conductivity is increased, thereby transferring the heat transferred from the heat medium to the mold mold 110 in a uniform distribution to the mesh fence ( The curing cycle of the mesh fence 10 may be shortened by maintaining thermal stability without temperature variation during the curing cycle of 10).

In addition, on the heat medium flow path between the heat medium heating part 137 and the inlet port 134 and the heat medium flow path between the heat medium cooling part 138 and the inlet port 134, a flow valve is opened and closed to control the discharge flow rate of the heat medium. 137a and 138a, pressure pumps 137b and 138b for applying pressure to allow the heat medium to flow at a predetermined pressure on the flow path, and to prevent backflow of the heat medium discharged through the pressure pumps 137b and 138b. Check valves (137c, 138c) may be provided for each.

In this way, the base material composition 20 injected into the molding groove 111 of the mold mold 110 and the reinforcing fibers 121 laminated in the form of a string and a blade in the base material composition 20 are laminated to the temperature control pipe. Since it is cured while heating and cooling through 130, it is possible to form a mesh fence 10 in a unitary structure having mechanical properties with excellent chemical resistance by completely chemical bonding.

The mesh fence stripping unit 140 is a component disposed under the mold frame 110 to demold the hardened and cooled mesh fence 10 to the outside of the molding groove 111. 2, a pressure pin 141, a pressure pin support frame 142, and a hydraulic cylinder 143 are provided.

The pressing pin 141 is disposed in the vertical direction on the upper portion of the mesh fence removal unit 140, the upper portion is inserted into the plurality of pressing pin holes 112 formed on the bottom surface of the forming groove 111 to be movable up and down. It is disposed, and is lifted by the hydraulic cylinder 143 to function to remove the pressurized mesh fence 10 to the upper portion hardened in the forming groove 111.

The pressure pin 141 is disposed so as to be parallel to the bottom surface of the forming groove 111 without the top surface protrudes in the original position as shown in the enlarged view of Figure 1, the pressure pin support frame 142 by the hydraulic cylinder 143 ) Is lifted up and protrudes to the bottom surface of the molding groove 111 through the pressing pin hole 112 of the molding groove 111.

The pressing pin support frame 142 is fixed to the pressing pin 141 so that the plurality of pressing pins 141 are disposed at positions corresponding to the positions of the respective pressing pin holes 112 formed in the mold die 110. Let's do it.

Here, although the pressing pin supporting frame 142 is formed by stacking a plurality of H-shaped steel in two stages, the present invention is not limited thereto, and the pressing pin 141 may be disposed at a corresponding position of the pressing pin hole 112. It can be in any form if the configuration can be moved up and down by receiving the pressing force of the hydraulic cylinder (143). However, it is preferable that the heights of the pressure pins 141 are mounted to be equal to each other so that the pressure pins 141 simultaneously move to the same ascent distance by the pressing force of the hydraulic cylinder 143.

The hydraulic cylinder 143 is a component for lifting and receiving the hydraulic pressure received from the hydraulic unit 145, is disposed in the vertical direction from the lower side of the pressing pin support frame 142 of the pressing pin support frame 142 It selectively lifts while pressurizing the lower part.

As shown in FIG. 7, the mesh fence remover 140 is connected to the hydraulic unit 145 and the hydraulic pneumatic inlet line 144 through which the hydraulic pressure is transmitted. When the hydraulic pressure is transmitted, the hydraulic cylinder 143 is upwardly directed. The pressure pin support frame 142 is pushed up and lifted while the pressure pin 141 protrudes to the bottom surface of the molding groove 111 through the pressing pin hole 112 of the molding groove 111, thereby forming The hardened mesh fence 10 in the groove 111 is pressurized upward to demold from the molding groove 111.

Briefly explaining the operation principle of the mesh fence forming means 100 according to the preferred embodiment of the present invention, first, about half of the base material composition 20 is injected into the molding groove 111 of the mold die 110. In one state, while moving the reinforcing fiber supply unit 120 disposed in the upper portion of the mold mold 110 in a zigzag manner, the reinforcing fibers 121 are divided by the string forming space portion 111a and the blade forming space portion 111b. Then alternately impregnated in a cross shape is discharged so that the reinforcing fibers 121 are laminated in a plurality of layers in the base material composition (20).

Subsequently, about half of the base material composition 20 is injected into the molding groove part 111 of the mold mold 110 to fill the base material composition 20 in the molding groove part 111. The base material composition 20 and the reinforcing fiber 121 disposed in the molding groove 111 of the hardening are bonded to each other chemically.

At this time, in the mesh fence forming means 100 according to a preferred embodiment of the present invention to heat the mold 110 to a predetermined temperature in order to shorten the time cycle required to cure, the heating medium heating part 137 The heating medium is heated to 80 degrees to 90 degrees according to a preset temperature, and the heated heating medium is discharged and introduced into the inlet 134 of the temperature control pipe 130.
