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 article using the resin mold 200, as shown in (I), the resin mold 200 is formed.
A frame 204 is set up along the outer peripheral edge of the
The concrete material 208A in a fluidized state is poured into a molding space 206 formed by the frame 00 and the frame 204. After curing, the concrete molded product 20 having the decorative surface 210 having an irregular uneven surface corresponding to the molding surface 202 of the resin mold 200 is obtained by removing the mold.
Get 8.

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 base material 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 motor 2
The two liquids are mixed by rotating the screw-type mixer 216 by using the mixture 18, and the mixed liquid is poured into the lower mold 220 for resin mold molding from the downward pouring pipe 219.
The resin mold 2 is poured out while being moved in the horizontal direction, poured into the mold 220, and then cured to form the resin mold 2.
00.

However, in the case of this apparatus, the resin mold 20
In pouring a mixed liquid of the resin base material liquid and the hardener liquid into the mold 220 for molding, the mold 2 is moved to a position below the discharge pipe 219.

And a mixing element 224 inserted therein.
It is also considered to use a static mixer 226 having the following. This static mixer 226
The resin base material liquid and the hardener liquid flowing into the housing tube 222 can be mixed and stirred by the action of the mixing and stirring blades 228 of the mixing element 224 while flowing through the inside of the housing tube 222 as it is. When 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.

However, when such a static mixer 226 is used, in order to sufficiently mix and stir a large amount of the resin base material liquid and the curing agent liquid in a short time and pour it out, the static mixer 226 must be thick and thick. It is necessary to use a long one.

However, if the length of the static mixer is increased, the operation of pouring and supplying the mixed liquid to the mold 220 becomes difficult. In particular, by moving the static mixer 226, the mixed liquid is discharged from the opening at the tip of the pouring pipe into the mold 220.
If it is attempted to supply and supply the liquid to all corners of the inside, there arises a problem that the operation of supplying and supplying the mixed liquid involves great difficulty.

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, the carriage 14 is connected to the rail 2
By moving it along zero and by turning the swivel arm 38, the mixing and pouring device 34 can be easily positioned at a desired position.

Next, the pumps 26 and 28 are operated to transfer the resin base liquid and the hardener liquid in the tanks 22 and 24 to the tubes 30 and 24.
It is sent out to the mixing and discharging device 34 through 32. Here, the mixing and discharging device 34 includes the movement of the carriage 14 and the pump 26,
An operation unit (not shown) for operating / stopping the operation of the mixing / dispensing device 34 is provided.
Each operation can be performed with the handle 60 of the operator, that is, the operator's hand.

In this example, the viscosities of the resin base material liquid and the curing agent liquid are about 5000 cp and about 5300 cp, respectively.
The one of 0 cp is used.

The resin base liquid and the hardener liquid sent out by the pumps 26 and 28 join together 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 pipe 62 in a snake-like form as a whole, and first, the resin base material liquid and the curing agent 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.

Next, the mixed liquid is caused to flow from the straight pipe section 62A-1 to the connecting pipe 62B-1, and the flow direction thereof is changed by 180 ° in the connecting pipe 62B-1. The mixture is allowed to flow into the straight pipe section 62A-2, where it is again mixed and stirred by the mixing element 64-2.

In this way, the mixed liquid flows through the connecting pipe and the straight pipe section of the housing pipe 62 alternately, whereby the mixed liquid is sufficiently mixed and stirred by the mixing elements 64-3, 64-4 and 64-5. Then, the mixed liquid of the resin base material liquid and the curing agent liquid that has been sufficiently mixed and stirred is poured into the mold 12 through the opening 54 of the discharge pipe 46. At this time, the operator freely adjusts the position of the mixing / dispensing device 34 which is swingably suspended via the wire 40 with the swivel arm 38, and uniformly discharges the mixed liquid to every corner inside the mold 12. be able to.

When a predetermined amount of the mixed solution is poured into the mold 12, 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 main resin solution and the curing agent liquid. Thereafter, the resin mold is released from the mold 12. Here, a resin mold molded into a desired shape is obtained. In addition, base 1
By arranging a plurality of dies 12 on 0 and moving the trolley 14, the work of pouring into each of the dies 12 may be performed continuously.

As described above, in the apparatus of this embodiment, since the static mixer 44 is formed in a snake-like form, a length necessary for sufficiently mixing and stirring the resin base material liquid and the curing agent liquid is secured. In addition, the vertical dimension of the static mixer 44 can be made sufficiently short.

Therefore, when the resin main agent liquid and the curing agent liquid are poured into the mold 12 for resin molding in a mixed state by the mixing / dispensing device 34 having the static mixer 44 as a main element, the same work should be performed with good workability. Can be. Further, 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 static mixer having a straight shape 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.

Incidentally, in this example, the length (L) of the straight pipe portion 62A is about 30 cm, the vertical dimension of the mixing / pouring device 34 is short, and the number of the straight pipe portions 62A is five. As a result, 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.

Further, in the apparatus of this embodiment, the position of the mixing and pouring device 34 can be moved based on the movement of the carriage 14 and the swiveling movement of the swivel arm 38. Therefore, the mold 12 for molding the resin mold is moved. If not, the mixing / dispensing device 34
Is moved, the mixed liquid of the resin base liquid and the hardener liquid can be poured into the mold 12.

Further, the mixing / dispensing device 34 includes a wire 40
, And can be freely swung over an angle range of 360 ° C., so that the position of the mixing and pouring device 34, more specifically, the tip position of the pouring tube 46 for pouring the mixed solution, can be freely controlled. In addition, the mixed solution can be easily and accurately and evenly poured and filled to every corner inside the mold 12.

Although the embodiment of the present invention has been described in detail, this is merely an example, and the present invention can be configured in variously modified forms without departing from the gist thereof.
