TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a resin mold for pouring a concrete material in a fluid state into a predetermined shape.
[0002]
Problems to be solved by the prior art and the invention
BACKGROUND ART Conventionally, a concrete material in a flowing state has been poured into a resin mold to obtain a concrete molded product having a decorative surface having irregular uneven surfaces, and used as an exterior building material or the like.
[0003]
FIG. 7 shows a procedure for manufacturing a concrete molded product using the resin mold.
In the figure, reference numeral 200 denotes a resin mold having a molding surface 202 having an irregular uneven shape.
In order to mold a concrete molded product using the resin mold 200, a frame 204 is set up along the outer peripheral edge of the resin mold 200 as shown in FIG. The flowing concrete material 208A is poured into the formed molding space 206. After curing, the molded product is removed from the mold to obtain a concrete molded product 208 having a decorative surface 210 having an irregular uneven surface corresponding to the molding surface 202 of the resin mold 200.
[0004]
Conventionally, the resin mold 200 is made of a polyurethane material, and the resin mold 200 made of the polyurethane material has been manufactured using an apparatus as shown in FIG.
Specifically, the resin main agent liquid and the curing agent liquid separately sent by the pump 212 are introduced into the screw mixer 216 by operating the valve 214, and the screw mixer 216 is rotated by the motor 218. After mixing the two liquids, the mixed liquid is poured from the downward pouring pipe 219 into the lower mold 220 for resin mold molding while moving the mold 220 in the horizontal direction, and poured into the mold 220. Thereafter, the resin mold 200 is cured to obtain the resin mold 200.
[0005]
However, in the case of this apparatus, the mold 220 must be brought down to below the pouring pipe 219 when the mixed liquid of the resin base material liquid and the curing agent liquid is poured into the mold 220 for molding the resin mold 200. At the same time, the mold 220 has to be moved in the horizontal direction during the pouring of the mixed solution so that the mixed solution spreads to all corners inside the mold 220, which causes a problem that a heavy burden is imposed on an operator.
[0006]
In casting the resin mold 200, instead of the screw mixer, a static mixer 226 as shown in FIG. 9, that is, a static mixer 226 having a housing tube 222 and a mixing element 224 inserted therein. It is also considered to use.
The static mixer 226 can mix and stir the resin base material liquid and the hardener liquid flowing into the housing tube 222 by the action of the mixing and stirring blades 228 of the mixing element 224 while allowing the inside of the housing tube 222 to flow as it is. Therefore, when such a static mixer 226 is used, simply passing the two liquids through the inside of the housing tube 222 allows the two liquids to be satisfactorily mixed and stirred and then poured out, which is convenient.
[0007]
However, when such a static mixer 226 is used, in order to mix and stir a large amount of the resin base material liquid and the curing agent liquid in a short period of time and to pour it out sufficiently, the static mixer 226 must be thick and long. It is necessary to use a long one.
[0008]
However, when the length of the static mixer is increased, the operation of pouring and supplying the mixed liquid to the mold 220 becomes difficult. If it is attempted to perform the supply and supply, the problem arises that the operation of supplying and supplying the mixed liquid involves great difficulty.
[0009]

Next, a procedure for manufacturing a resin mold using the apparatus of this embodiment will be described.
First, the mold 12 is set on the upper surface of the bed 10, and the mixing and pouring device 34 is moved to position the mixing and pouring device 34 on the mold 12.
At this time, by moving the carriage 14 along the rail 20 and turning the turning arm 38, the mixing and pouring device 34 can be easily positioned at a desired position.
[0029]
Next, the pumps 26 and 28 are operated to send the resin base liquid and the hardener liquid in the tanks 22 and 24 to the mixing / pouring device 34 through the tubes 30 and 32.
Here, the mixing / pouring device 34 is provided with an operation unit (not shown) for operating the movement of the carriage 14 and the operation / stop of the pumps 26 and 28, whereby an operator can operate the mixing / pouring device 34. Each operation can be performed while holding the handle 60, that is, near the operator.
[0030]
In this example, the resin base material liquid and the curing agent liquid having viscosities of about 5000 cp and about 53000 cp, respectively, are used.
[0031]
The resin base liquid and the hardener liquid sent out by the pumps 26 and 28 merge in the inflow pipe 48 and flow into the static mixer 44.
As shown in FIG. 6, the static mixer 44 of this example has a housing tube 62 in a snake-like form as a whole, and first, the resin base material liquid and the hardener liquid are supplied to the straight pipe portion 62A-1. The two liquids are mixed and stirred together by the action of the blade 66 of the mixing element 64-1.
[0032]

[0034]
After the mixture is poured into the mold 12 in a predetermined amount, the pumps 26 and 28 are stopped, and the mold 12 is placed in a heating furnace and heated to cause a curing reaction between the resin base material liquid and the curing agent liquid. Release the resin mold from 12. Here, a resin mold molded into a desired shape is obtained.
It should be noted that a plurality of dies 12 may be arranged on the base 10 and the carriage 14 may be moved to continuously perform the work of pouring the dies 12 into the respective dies 12.
[0035]
As described above, in the apparatus of the present example, the static mixer 44 has a snake-like meandering form, while ensuring a length necessary for sufficiently mixing and stirring the resin base material liquid and the curing agent liquid, The vertical dimension of the static mixer 44 can be made sufficiently short.
[0036]
Therefore, when the mixing and pouring device 34 having the static mixer 44 as a main component, the resin main agent liquid and the curing agent liquid are poured into the mold 12 for resin molding in a mixed state, the same operation can be performed with good workability.
In addition, since the static mixer 44 has the mixing element 64 inserted only inside the straight pipe portion 62A, it can be easily constructed simply by connecting a commercially available straight-shaped static mixer with a U-shaped pipe. By simply increasing or decreasing the number of connections, the entire pipe length can be easily adjusted to a desired pipe length.
[0037]
Incidentally, in this example, the length (L) of the straight pipe portion 62A is about 30 cm, the vertical dimension of the mixing and pouring device 34 is short, and the number of the straight pipe portions 62A is five. Thus, the entire length of the static mixer 44 required for sufficiently mixing and stirring the resin base material liquid and the curing agent liquid is 1.5 m.
In addition, the supply amount of the mixed liquid is a maximum of 20 liter / min.
[0038]
Further, in the apparatus of the present embodiment, the position of the mixing and pouring apparatus 34 can be moved based on the movement of the carriage 14 and the swiveling movement of the swivel arm 38, and therefore, the mold 12 for resin molding does not need to be moved. By moving the mixing / dispensing device 34, the mixed liquid of the resin base liquid and the curing agent liquid can be discharged into the mold 12.
[0039]
Furthermore, since the mixing / pouring device 34 is swingably hung over an angle range of 360 ° C. via the wire 40, the position of the mixing / pouring device 34, more specifically, the discharging for discharging the mixed liquid. The position of the distal end of the tube 46 can be freely controlled, and the mixed solution can be easily and accurately and evenly poured and filled into every corner inside the mold 12.
