[Detailed explanation of the invention] This invention is a foamed synthetic resin bread (bun 5tock)
The purpose is to provide a mold for economically producing foamed synthetic resin bread with high homogeneity. .

Conventionally, as a means of producing foamed synthetic resin breads made of polyisocyanurate foam, polyurethane foam, etc. in a batch process, a box-shaped mold of about 0.5 to 1.5 m, which has sufficient strength to withstand the foaming pressure, is used. The method used includes injecting a foaming solution, foaming, solidifying, curing, and then demolding.

However, in the conventional method, the free growth of air bubbles is suppressed by a strong mold during the process of producing foamed synthetic resin, so the air bubbles themselves have great directionality and the objects of each part of the produced bread are markedly different. When bread is secondary processed into boards, pipe covers, etc. and used as a heat insulating material, there is a risk that phenomena harmful to heat insulation such as significant changes and cracks may occur. Due to foaming, a large internal stress is generated, which remains in the bread and causes the object to deteriorate, and it is necessary to cure the bread in a mold until the bread develops the strength to self-retain this stress. The curing time is 3 to 10 hours, and therefore, the rotation rate of the mold is low, and a large number of expensive molds are required.The conventional method has disadvantages in terms of both physical properties and economy.

Initially, the foaming stock solution has fluidity like water, but when the foaming reaches 20 to 30%, the fluidity decreases and becomes cream-like, and it no longer leaks from the joint between the side wall plates. The height of the sealing material 9 disposed at 12 from the bottom surface may be 30 to 50% of the final foaming height of the bread.

In addition, the above-mentioned mold release box 11 is not used as the sealing material 9, and as shown in Figs. Additionally, a cushion gasket 14 made of a sheet material such as polyethylene foam, soft urethane foam, or soft polyvinyl chloride foam may be interposed at each mating portion.

発泡原液の発泡初期の流動性の高い時点においては側壁

Since there is no movement of the foaming solution to the outside of the side wall plates when the fluidity of the foaming stock solution is high at the initial stage of foaming, leakage of the stock solution from the joints of the side wall plates is prevented.

Alternatively, adhesive tape may be applied as the sealing material 9 to cover the joints between the bottom plate and the side wall plates and the joints between the side wall plates to prevent leakage of the foaming stock solution from the joints.

粘着テープは側壁板に発泡合成樹脂の発泡圧がかかれば
簡単に剥がれるので、側壁板が発泡圧によって外側に移
動することを妨げない。
Since the adhesive tape is easily peeled off when the foaming pressure of the foamed synthetic resin is applied to the side wall plate, it does not prevent the side wall plate from moving outward due to the foaming pressure.

り外しを容易にするために離型剤が施されている。
Furthermore, a mold release agent is applied to the inner surface 6 of the box-shaped surrounding wall to facilitate removal of the foamed synthetic resin pan 15.

When the foaming stock solution is injected into the mold configured in this way, the foaming stock solution starts foaming within 30 seconds to several minutes, and the ice-like foaming stock solution gradually becomes cream-like and expands upward in the molding space 4. Teku.

At this point, the foamed synthetic resin has ice-like or cream-like fluidity, so the volume expansion due to foaming is only directed upward, which is open, and almost no foaming pressure is applied to the side wall panels. does not move outward.

When the foaming reaches about 70% of the final foaming rate, the cream-like fluidity rapidly disappears, and the foamed synthetic resin becomes a semi-hard sponge beast and expands further, so a large foaming pressure is applied to the side wall plate. The side wall plate moves outward and the foamed synthetic resin also expands laterally (at this time, the folded release box 11
(also spreads outward).

この時点では発泡合成樹脂は半硬質の状態なので、底板

At this point, the foamed synthetic resin is in a semi-rigid state, so even if the joints between the bottom plate and the side wall plates and the joints between the side wall plates are opened, the foamed synthetic resin will not flow out from the gaps.

側壁板が移動する距離は側壁板の幅の10〜20%程度

A floating plate (not shown) with a weight of 10 to 100 kg/m is placed on top of the stock solution that has been foamed to a final foaming rate of 30 to 70%.
If you put it on, a bread with less curvature on the top surface will be generated, so
This has the effect of improving yield.

According to this invention, the mold is configured to expand freely under the foaming pressure as the foamed synthetic resin foams, so the air bubbles are not restrained and are allowed to lengthen freely, resulting in highly isotropic properties. A foamed synthetic resin pan is produced which is homogeneous and has excellent physical properties without any weaknesses in use.

In addition, since the bread is produced in a free-foamed form, there is almost no internal stress, so there is no particular need for curing in the mold, and the mold can be removed 10 to 60 minutes after the foaming is finished. The turnover rate is extremely high, making it possible to efficiently produce bread with a small number of molds.
