Description

[Detailed Description of the Invention] Regarding the manufacturing method, we have made it possible to mass produce a storage box made of reinforced plastic that is lightweight, has excellent corrosion resistance, and has excellent impact resistance.
Our aim is to provide high quality storage boxes at low prices.

Its features are -1':, which is molded with F'RP resin, with the flange part protruding outwards on the back side, and the stepped part for the door opening 1-1. The top wall, bottom wall, and left and right side walls are integrally molded using the side I type.
Next, after molding the back wall, a mold release table is inserted through the opening 11 and applied to the inner surface of the back wall, and a support member is applied to the back side of the flange part. C) Pressure is applied to the mold release table or the support member. The purpose of this is to release the outer mold from the opening side.

Next, based on the first feature, an embodiment will be described with reference to accompanying drawings.

△ Prepare the mold 2, and polish the surfaces of the outer mold 1 and the inner mold 2 with a wax-like mold release agent, and then apply an al:nol based agent. After drying -1- was sprayed, and after drying for about 30 minutes at 0', leave it for a time or until the next morning when working at night.

As shown in FIGS. 1A and 1B, an outer mold 1 and an inner mold 2 are set, and FRP resin 3 is injected into the mold to form a top wall 4a.

The bottom wall 4b and the left and right side walls 4C are integrally molded.

After curing, the inner mold 2 is released from the back side 11 part. In this case, the FINP resin 3 may be laminated on the inner mold 1 without using the inner mold 2.

Place the pre-formed gel-coated F' RP resin back wall 4d on the - side of the back mold 8 of 1 on the stand 5 as shown in Fig. 2, and rotate the outer mold 1 so that the back wall 4d faces in the opposite direction. It fits into a frame body 4e consisting of a top wall 4a, a bottom wall 4b, and left and right side walls 4C which were previously integrally molded. Further, the outer mold 1 is pressed onto the stand 5 with rubber or a spring, etc., and putty (not shown) of the same color as the gel coat is applied to the joint between the frame 4e and the back wall 4d.

The main body 4 is formed by laminating the FRP resin 3 from the inside of the rear wall 4d with the putty solidified.

Also, if necessary, identify partition plates (not shown) and attach them by laminating FRP resin. Then put it in the drying room. It goes without saying that the back wall may not be molded in advance, but may be laminated or laminated or molded to a size of l+''.

After curing, remove the outer mold 1 from the stand 5, and as shown in FIG. I'll put it on.

After that, apply oil 11 and jack 7 to the flange 1a of the outer mold 1.
The outer mold 1 is forcibly released from the 11 part 4f side by applying an IE force to the support part vJ7a such as the above.

After releasing the mold, the edges of the hair body 4 shown in FIG. 9 (A>(B)) are cut, and an FRP door (not shown) is removed in the usual manner to obtain a product.

The reinforced plastics used in the present invention include thermosetting resins such as unsaturated polyester resins, epoxy resins, melamine resins, phenolic resins, silicone resins, etc. All reinforcing materials such as fibers, fibers, synthetic fibers, and synthetic fibers. All products that have been hardened and molded.

Alternatively, chopped strand mats, loaching cloth glass fibers, etc. may be laminated, impregnated with an unsaturated polyester resin, etc., and an unsaturated polyester resin in which paraffin is dissolved is coated on the surface of the laminated glass fibers, etc., and heated and cured to form the product.

As described in 1, the present invention is made of reinforced plastic 3 made of unsaturated polyester, with an outwardly protruding flange portion 1a on the back side, and a stepped portion 1b on the door opening [1 part 4f side]. using the top wall 4a, bottom wall 4b,
After forming the left and right side walls 4c, and then forming the back wall 4d, a mold release table 6 is inserted from the door gap 1 part 4f and applied to the inner surface of the back wall 4d, and the back wall of the flange portion 1a is By applying pressure to the mold release table 6 or the Gj support member 7a after applying the support member 7a to the side, the mold 1 is released from the opening part 4f side and a reinforced plastic storage box is molded. From this, we efficiently produced a beautiful storage box that is lightweight, has excellent strength such as corrosion resistance and shock resistance, and does not show any joint 1.1, using NF7R'F plastic molding and mold release work. Since it comes with 1+, it has an excellent effect.

Claims (1)

[Claims] Made of reinforced plastic made by hardening and molding unsaturated polyester resin, etc. with a reinforcing phase such as glass fiber, it has an I-shaped structure with 7 rungs protruding toward the back side and a stepped section on the -4 side. After molding the top wall, bottom wall, and left and right side walls integrally, and then molding the back wall, a mold release table is inserted through the door opening 11 and applied to the inner surface of the back wall, and the back wall of the seven rungs is Place the support member on the side and then press l-E on the mold release table or support member.
A method for manufacturing a storage box for fire extinguishing equipment, etc., characterized in that the outer mold is released from the door opening L-1 side by applying force, and the storage box is molded from reinforced plastic.
