The present invention relates to a multi-stage compression molding mold for FRP molded products, in which an upper mold plate 2 is provided on the lower surface of a press upper surface plate 1, and a lower mold plate 4 is provided on the upper surface of the press lower surface plate 3,
At least one medium plate 5 is arranged between the upper mold plate and the lower mold plate 4, a cavity 6 is formed between the vertically adjacent mold plates 2, 4, and 5, and a cavity 6 is formed between the upper and lower press plates 1. The upper guide pin 13 hanging downward is slidably inserted into the vertical guide hole 11 of the medium plate 5, and a flange 14 is provided at the lower end of the upper guide pin 13 to lock onto the medium plate 5. The lower guide pin 12 protruding upward is inserted into the guide hole 11 of the medium-sized plate 5.
The multi-stage compression molded metal is characterized in that the lower guide pin 12 can be slidably inserted into the guide recess 16 provided in the vertical direction from the lower end of the upper guide pin 13. It is related to the mold. When compression molding FRP (fiber-reinforced plastic) molded products, if multiple molded products are to be molded, multiple upper molds 7 are mounted on the upper surface plate 1 on the movable side of the press, as shown in conventional Fig. 1. Molding was carried out by attaching the lower molds 8 in parallel to the lower press surface plate 3 on the stationary side. However, in this case, the upper mold 7 and the lower mold 8 are installed in parallel on the press upper surface plate 1 and the press lower surface plate 3, so each of the upper mold 7 and the lower mold 8 is small (for example, 1000 x 1500 mm). In addition, since the press pressure is distributed to each upper mold 7 and lower mold 8, the molding pressure is also reduced, and large molded products (e.g. 2500~ 2500mm) cannot be formed. The present invention has been made in view of the above points, and is a multi-stage multi-stage molded product that can be molded with multiple molds even for large molded products, and that press energy can be effectively used for molding without the risk of energy loss. The object is to provide a compression molding mold. The present invention will be explained in detail below with reference to Examples. The compression molding mold according to the present invention, as schematically shown in FIG.
An upper mold plate 2 is provided on the lower surface of a movable press upper surface plate 1, a lower mold plate 4 is provided on the upper surface of a fixed press lower surface plate 3, and a middle mold plate 5 is provided between the upper mold plate 2 and the lower mold plate 4. A cavity 6 is recessed in the lower surface of the upper mold plate 2 and the lower surface of the middle mold plate 5, and a core 9 is provided protruding from the upper surface of the middle mold plate 5 and the lower surface of the lower mold plate 4. By using one medium plate 5, molding can be performed in two stages between the upper surface of the medium plate 5 and the lower surface of the upper mold plate 2, and between the lower surface of the intermediate plate 5 and the upper surface of the lower mold plate 4. It is possible to use two or more medium-sized plates 5, an upper template 2 and a lower template 4.
By arranging them in the vertical direction between them, it is possible to carry out molding in even more stages. Figure 3 shows cavities 6, 6 on the upper and lower surfaces of the medium-sized plate 5.
cores 9 and 9 are formed on the upper mold plate 2 and lower mold plate 4, respectively, and a heat medium such as steam is passed through the upper mold plate 2, the lower mold plate 4, and the middle mold plate 5 through a heat exchange pipe 10. Heating is achieved through communication. Further, a vertical guide hole 11 is formed in the medium plate 5.
The lower guide pin 12 of the upper mold plate 4 and the upper guide pin 13 of the upper mold plate 2 are slidably passed through the upper mold plate 4, and the middle plate 5 is engaged with the collar 14 at the lower end of the upper guide pin 13, thereby It is designed to be held on plate 2. However, when molding, for example, FRP sheet molding compound (SMC) material with a lever mold, the SMC molding compound 15, 15
are placed on the middle plate 5 and the lower plate 4, and then the upper plate 2 is lowered using a press (not shown). Then, as the upper mold plate 2 descends, the middle mold plate 5 also descends while being guided by the lower guide pin 12, and the lower guide pin 12 is inserted into the guide recess 16 of the upper guide pin 13, thereby connecting the middle mold plate 5 and the lower mold. The molding materials 15, 15 are pressurized between the plate 4, the upper mold plate 2, and the middle mold plate 5 to be molded. When the press machine lifts the upper mold plate 2 after molding is completed, the upper mold plate 2 rises by the length of the upper guide pin 13 and is then locked by the collar 14, and the middle mold plate 5 is also lifted up, opening the mold. is to be carried out. Here, since the upper mold plate 2, the middle mold plate 5, and the lower mold plate 4 are vertically arranged in series, the pressing force from the press machine acts on each molding material 15, 15 as it is, and the number of molding stages is increased. There is no need to increase the pressing force, and in order to obtain two molded products, the heating medium only needs to be passed through three places: the upper mold plate 2, the middle mold plate 5, and the lower mold plate 4. Compared to the case where the heat medium is passed through two places, the upper mold and the lower mold, for one molded product, the energy of the heat medium per molded product can be reduced. As described above, in the present invention, at least one medium plate is disposed between an upper mold plate and a lower mold plate, and a cavity is formed between the vertically adjacent mold plates. It is possible to mold many cavities in series between the upper surface plate and the lower press surface plate, and the molding pressure is directly applied to each cavity by the press machine, so even large molded products can be molded in large numbers without any problem. It is possible to perform individual compression molding, allowing for the production of large molded products with high productivity.In addition, since the pressure of the press is directly transmitted to each cavity, the amount of press required per molded product is reduced. This allows the machine operating power to be reduced. In addition, the upper guide pin hanging downward from the press upper surface plate is slidably inserted into the vertical guide hole of the medium plate, and the lower end of the upper guide pin is provided with a flange that locks to the medium plate. The lower guide pin protruding from the upper guide pin is slidably inserted into the guide hole of the medium plate, and the lower guide pin is slidably inserted into the guide recess provided vertically from the lower end of the upper guide pin. Therefore, when the molding material is set between the upper mold plate and the middle mold plate and between the middle mold plate and the lower mold plate and the upper mold plate is lowered, the middle mold plate also lowers as the upper mold plate descends. It descends while being guided by the guide pin, the lower guide pin is inserted into the guide recess of the upper guide pin, and molding is performed between the middle mold plate and the upper mold plate and the lower mold plate, and when the upper mold plate is raised after molding. After the upper mold plate has been raised by the length of the upper guide pin, the collar is locked and the middle mold plate is also raised to open the mold, and the middle mold plate can be used to perform multi-cavity molding. Despite this, there is no need for a special drive source to drive the middle plate, and the distance between the upper die plate and the middle plate can be easily moved by simply driving the upper surface plate of the press, on which the upper die plate is located, up and down. It has the advantage of being able to open and close the mold between the middle mold plate and the lower mold plate, and is precisely positioned by the guiding action of the guide hole, upper guide pin, lower guide pin, and guide recessed hole. The mold plate can be clamped between the upper mold plate, the middle mold plate, and the lower mold plate, and accurate molding can be maintained even though the number of molds is increased by adding the middle mold plate. Furthermore, even if the mold is constructed so that it can be opened so that the distance between the middle mold plate and the upper mold plate or the lower mold plate is widened, the mold can be clamped and the molding die does not become large. Next, an experimental example of the present invention will be shown. Experimental Example 1 Using the mold shown in FIG. 3, an outer box 19 of a heat sink plate for a solar heater having a shape as shown in FIG. 4 was molded. The size of the outer box is width 1200mm, length 2000mm, depth
It was 80mm. The composition of the SMC molding material is as follows.

[Table] In the case of two-stage molding, the molding time per piece is 270/
Since 2 = 135 seconds, it can be seen that productivity is greatly improved. In addition, the power consumption for driving the press during press pressurization is reduced to 1/2 in two-stage molding compared to one-stage molding per molded product, and the steam cost for heating the mold is lower in two-stage molding than in single-stage molding. 3/per molded product
It decreased to 8.
