Next, the operation will be described. In FIG. 5, the main agent (resin) flows in from the inlet of A, and the other one liquid (catalyst) flows in from C. The two liquids are mixed by the rotating blades 51 rotating during the transfer in the cylinder 53, and the discharge port B
And then injected into a mold installed after the molding device. At this time, by providing the fixed blade 52 in the cylinder 53, the mixing efficiency is improved. By the way, this type of molding apparatus is characterized in that a necessary amount can be mixed when needed. The reason is that when the catalyst is mixed with the resin, it is very easy to cure. Therefore, the resin is usually mixed immediately before injection into the mold and mixed while being injected.

The rotational force of the rotating blades 51 is transmitted to the pulley 69 via a belt by a motor (not shown) from the outside. At this time, the mechanical seal portion 57 is inserted and rotationally sealed so that the resin does not leak outside. Lubrication of the rotary seal portion and heat generated by sliding are disposed outside the mechanical seal portion 57. Lubricating oil 5 encapsulated in damaged oil waste 58

Next, the operation of the catalyst inlet 96 will be described with reference to FIG. Usually, the through-hole 109a, which is the outlet of the catalyst, is closed by the elastic force of the Teflon tube 101. When a catalyst having a pressure equal to or higher than a predetermined pressure is supplied from the pipe 108, the tube 101 is elastically deformed, and the catalyst passes through the through hole 1
09a and the tube 101 are released. As described above, the catalyst injection port 96 has a function of not leaking the catalyst except at the time of injection of the catalyst, and of injecting the catalyst into the main agent, but preventing the main agent from flowing backward. Tube holder 10

[0012]

In this type of apparatus, it is important to raise the temperature of the resin and control the temperature. In other words, the resin temperature and the resin curing time greatly differ depending on the type of the resin. For example, if there is a resin that practically cures (this is usually referred to as gelation) at 150 ° C. and 30 seconds, this resin is 100%. At 0 ° C., a gel time of 12.5 minutes is required. However, in the conventional molding apparatus, it was not possible to control the temperature of the resin rather than to control it. That is, although the resin temperature was increased by stirring the resin, it did not reach the control. Conversely, there is a fear that the temperature will rise and the inside of the device will be hardened.

When the temperature of the resin is not increased as in the prior art, since the discharge temperature of the resin is at most about 60 ° C., the mold is set in advance to the gelling temperature, and The resin was heated by heat conduction. However, in this method, since the thermal conductivity of the resin is not so good, if a product requiring 500 cc of resin is to be molded, the resin temperature is increased from 60 ° C. to 100 ° C.
It takes about 10 minutes to rise to Further, according to this method, since the resin temperature does not rise uniformly, an internal stress is caused and various adverse effects are caused.

Further, since the fixed blades in the above-mentioned conventional apparatus have a structure in which all the blades are fixed to one cylinder, there is a drawback that if the resin is hardened in the apparatus, disassembly becomes impossible. Was. In addition, since the Teflon tube is used for the catalyst injection port in the above-described conventional apparatus, the tube is plastically deformed in a short period of time,
There has been such a problem that a gap is formed in the diameter direction of the tube and the catalyst leaks or the main agent flows back into the catalyst line.
Further, in the above-described conventional apparatus, a screw portion is provided on the rotating shaft to prevent the resin from remaining or hardening inside the mechanical seal, and the function of a screw pump is provided. However, there is a problem that when the resin hardens inside the mechanical seal and the rotating blades do not rotate, the function does not come out sufficiently.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, disadvantages and problems, and an object of the present invention is to provide an apparatus for curing a resin.

(B) is an enlarged sectional side view. In these drawings, the same reference numerals are given to the same or equivalent components as those of the related art, and the detailed description is omitted.

The reference numeral 1 designates a plurality of cylinders formed in a ring shape as shown in detail in FIG. Eight pins 1a are implanted on the upper surface of the cylinder 1, and a pair of notches 1b are formed on the periphery. 1c is the cylinder 1
O-ring for preventing the resin from leaking from the stacking surface of. On the other hand, a hole 52a is provided in the fixed blade 52, and the fixed blade 52 is
Is fixed to the cylinder 1 by being prevented from rotating. In this manner, the cylinder 1 and the fixed blade 52 are sequentially stacked and assembled in the housing 2. By inserting the wedge 20 into the notch 1b, it can be easily disassembled. The housing 2 has a liquid introduction path 2 a formed so as to surround the fixed blade 52.

Reference numeral 3 denotes a heating cone disposed immediately before the discharge port C, which is integrated with the rotating shaft 51. Reference numeral 4 denotes a cone case, which forms a resin introduction path 3a having a small gap between the heating cone 3 and the heating case. In the cone case 4,
A liquid introduction hollow portion 4a is formed. 5 is a temperature sensor. Reference numeral 6 denotes an introduction pipe for introducing the hot / cold liquid into the heat generating cone 3. The introduction pipe 6 is elongated and is supported by the inner cylinder of the rotating shaft 51 by the intermediate support ring 9. The intermediate ring 9
Is press-fitted into the rotating shaft 51 to prevent the falling off.

Reference numeral 7 denotes a sealing material for preventing hot and cold liquids from leaking from the mating surface where the heating cone 3 is screwed to the rotating shaft 51 with an O-ring, and preventing resin from entering the heating cone 3 from outside to inside. is there. 8 is also an O-ring, which prevents the resin from leaking from the gap with the cone case 4 after the cylinder 1 is loaded. Reference numeral 10 denotes a liquid rotary joint having a function of introducing the liquid introduced from the inlet H into the rotating shaft 51 and the liquid introduction pipe 6 without leakage. Reference numeral 11 denotes a base plate of the entire apparatus, which is fixed to the apparatus main body by bolts 12.

The catalyst injection port 96 includes an injection port 30, a joint 32, and a pipe 33 as shown in detail in FIG. The injection port 30 is formed with a hollow portion 30 a communicating with the pipe 33 via the joint 32,
A through-hole 30b communicating with the outside of the injection port 30 is formed in the distal end portion of Oa. An annular groove 30c is provided on the outer peripheral surface of the injection port 30 where the through hole 30b is located, and a rubber O-ring 3 is provided in the groove 30c.
1 is fitted. An O-ring 34 prevents the resin from leaking outside the injection port 30. At the entrance of the entangled portion 14 on the mechanical seal portion 57 side, a partition plate 13 for partitioning the resin from the resin is provided with a slight gap 13 a in contact with the rotary shaft 51. Then, the sandwich portion 14 is filled with silicon grease from the entrance J.

Next, the operation will be described. The main agent (resin) flows in from the inlet A, and another liquid (catalyst) flows in from the inlet C. The two liquids are mixed by the rotation of the rotary blade 51 while being transported in the cylinder 1 and are discharged from the discharge port B to a mold (not shown). When the mixed resin passes through the resin introduction path 3a formed by the heating cone 3 and the cone case 4, frictional heat is generated and the temperature is raised. The frictional heat generated here is
The smaller the cross-sectional area of the resin introduction path 3a and the lower the flow velocity of the resin, the greater the amount of generation and the higher the temperature of the resin, but on the other hand, the lower the discharge speed of the resin. In addition, since the transfer resistance of the resin increases, a large transfer force is required.

Therefore, when it is necessary to further raise the temperature of the resin, hot liquid is introduced from the inlet H into the liquid introducing pipe 6 and from the inlet F into the liquid introducing hollow portion 4a, respectively.
The heating cone 3 and the cone case 4 are preheated. In this case, the temperature of the resin is 100
When the heating cone 3 and the cone case 4 were preheated to 80 ° C, there was a difference of about 30 ° C in comparison with the room temperature of 25 ° C, and the resin was heated to 130 ° C. Becomes possible. The resin discharge temperature to the mold is 30
If the temperature increases by 1 ° C., the gel time is reduced to 1/8, and the productivity is improved.

Here, it should be noted that if the resin temperature is increased in this apparatus until gelling takes several tens of seconds in this apparatus, there is a danger of gelling in the apparatus before discharging to a mold. That is. In order to prevent this, the heating cone 3 and the cone case 4 are cooled except when the resin is discharged.
In cooling the heating cone 3, like the hot liquid, a cold liquid is introduced from the inlet H and discharged from the outlet I. This hot liquid,
When the cooling liquid is poured and discharged, the rotating blades 51a are also preheated and cooled, and the effect of controlling the temperature rise of the resin is improved.

The liquid introduction passage 2 formed in the housing 2
By introducing a hot liquid and a cold liquid from the inlet D to the outlet a and discharging the liquid from the outlet G, the fixed blade 52 is also preheated and cooled, and the temperature rise control of the resin is more effective. Further, in order to further prevent gelation in the device, the effect is further enhanced by rapidly cooling the resin when the discharge of the resin from the device is completed.

Next, the operation of dismantling the fixed blade 52 will be described. In FIG. 3, reference numeral 15 denotes a resin that has gelled in the apparatus. When the resin gels in the apparatus as described above,
FIG. 3 is an exploded view of the components of the apparatus, such as the housing 2.
As shown in (a), an assembly unit of the rotating blade 51a and the fixed blade 52 is taken out. And the gelled resin 1
5 can be dug out with tools such as chisel. afterwards,
When the wedge 20 is driven into the notch 1b of the cylinder 1, the fixed blade 5
2 are removed one by one, so by removing them sequentially, all the fixed blades 52 can be removed from the cylinder 1. As described above, even if the resin gels in the apparatus, the fixed blades 52 can be easily disassembled, so that the fixed blades 52 that have been conventionally discarded can be regenerated.

Next, the injection operation of the catalyst will be described.
In FIG. 4, the catalyst enters the hollow portion 30a of the injection port 30 from the pipe 33 via the joint 32, and the O-ring 31 rises up from the groove 30c due to the pressure of the catalyst.
The liquid is discharged from a gap generated between the first through hole 30 and the through hole 30b.
When the catalyst is not discharged, the O-ring 31
b is closed, and the main agent does not flow into the catalyst. Since the O-ring 31 is formed in a ring shape and is made of rubber, the O-ring 31 retains its elasticity even when used for a long time, is easy to replace, and improves maintainability.

Next, the operation of the mechanical seal portion 57 will be described. Silicon grease is filled into the entangled portion 14 with a pressure slightly higher than the resin pressure from the inlet J,
The grease is forcibly discharged to the resin side from the gap 13a so that the resin does not enter the gap 13a and replace the grease with the resin in a short time. As described above, the entangled portion 14 is always filled with silicon so that the resin does not come into contact with the mechanical seal portion 57, so that the sealing property of the mechanical seal portion 57 is improved, and the life of the mechanical seal portion 57 is extended. Can be planned. The grease discharged to the resin side is not a problem because it is silicon grease that does not impair the characteristics of the resin.

In this embodiment, a liquid is used for preheating the heating cone, the cone case, and the like. However, the present invention is not limited to this, and the same effect as described above can be obtained by using a gas. is there. Although both the heating cone and the cone case are preheated, either one may be selected as necessary. In that case, when only the cone case is selected, the rotating shaft 51 is hollow. Without saying
Further, since the pipe 6 is not provided inside, the structure is extremely simplified.

[0035]

As described above, according to the present invention, the fixed blades are individually divided and fixed in a loaded state, so that, for example, even if the resin hardens in the apparatus, the fixed blades are fixed. Since the resin that has been decomposed and hardened can be easily removed, the fixed blade that had to be discarded in the past can be repaired and regenerated.

Further, the catalyst injection port was formed by a hollow cylinder, a through hole penetrating from the hollow portion of the cylinder to the periphery was provided, and a rubber O-ring was fitted around the cylinder to close the through hole. So, rubber O to close the through hole
The ring retains its elasticity over a long period of time, extending its service life.It also improves the reliability of the seal that prevents the resin from entering the cylinder, and is easy to replace. improves. In addition, between the mechanical seal portion and the thermosetting resin is filled with grease in a substantially sealed state,
Since the supply is made so that the mechanical seal portion does not come into contact with the resin, it is possible to achieve high reliability and a long life of the mechanical seal portion. Also discharge
