Description of the Related Art Since it is necessary to form a mounting hole for bolting and the like at the same time as forming a contour at the time of molding, the above-mentioned heat insulating material, soundproofing material, etc. have conventionally been formed as a molding die of this kind. 2. Description of the Related Art There has been known an apparatus in which a trimming portion for pushing and cutting for forming a punched hole at a desired position inside a body contour is bolted to a mold body. When the cutting edge of the trimming portion for wear and tear is worn, the trimming portion for trimming for push and release is removed from the die body, and the height of the blade portion is adjusted by welding and polishing. In this type of mold, the height of the blade portion of the trimming portion for cutting off is 2.5 to 3 mm.
It is necessary to adjust the height when it becomes about 2 mm due to wear. On the other hand, it is considered that the cutting edge angle of the push cutting blade is preferably about 90 to 60 °.

Therefore, an object of the present invention is to extend the life of the trimming section for push-off without lowering the productivity. In particular, the present invention pays attention to the fact that, in the case of wear, the height of the blade portion has a greater effect on trimming than the angle of the blade edge, and aims to extend the life of the trimming portion for push-off by a simple method. It is intended to be.

能となる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is directed to a case where a blade portion is worn by providing a spacer for adjusting the height of the blade portion of the trimming portion for cutting off between the trimming portion for cutting off and the die body. With this spacer, the blade portion can be adjusted so as to have a sufficient height from the mold body. Therefore, for example, before the blade is worn, no spacer is provided, and when the blade is worn, the spacer is provided to adjust the height of the blade. It is also possible to use spacers having different thicknesses or to change the number of inserted spacers depending on the degree of wear of the blade portion. The present invention focuses on the effect of the height of the blade portion on trimming, and extends the life of the trimming portion for push-off by a simple method, so that when the blade edge angle does not maintain the predetermined angle anymore. It is necessary to adjust the angle of the blade edge by polishing, which makes it possible to further extend the life of the trimming portion for pushing and cutting.

FIG. 1 is a cross-sectional view of a mold body for molding showing the same embodiment, FIG. 2 is an enlarged cross-sectional view of a trimming portion for push-off without using a spacer, and FIG. 3 is an enlarged view showing a detached state of trimming for push-off. FIG. 4 is an enlarged cross-sectional view of the trimming portion for pushing off with a spacer inserted.
First, the configuration of the mold body will be described with reference to FIG. In the figure, reference numeral 10 denotes an upper mold, reference numeral 20 denotes a lower mold, and upper mold 1
Numeral 0 denotes a heat-molded portion 12 formed in the mold body 11 in the form of a female mold according to the shape of the molded body 30, a trimming portion 13 for cutting off according to the contour shape of the molded body 30, and a desired shape inside the contour of the molded body 30. And a push-off trimming section 40 for forming a punched hole at a location. In the drawing, reference numeral 41 denotes a blade provided in the trimming section 40 for pushing off. Also, the lower mold 20
The mold body 21 is provided with a heat-formed portion 22 formed in a male mold in accordance with the shape of the molded body 30. Here, the upper and lower molds 10 and 20 are made of an aluminum material, and the trimming section 1 for pushing and cutting is used.
3 is preferably made of an iron material. That is, by making the upper and lower molds 10 and 20 lightweight aluminum materials having a small heat capacity, it is possible to reduce the weight of the molding mold and to shorten the time required for temperature rise. In addition, the trimming process can be favorably performed by using the iron material having high mechanical strength for the trimming portion 13 for pushing and cutting. In addition, since the iron material has a larger thermal expansion than the aluminum material, the gap between the two members is completely filled from the adjacent mold body 11 at the time of heat molding, and the heat contraction is large at the time of cooling, so that the gap is restored as before. Since the holding portion is held, the push-off trimming portion can be easily removed. The molded article molded with the above-mentioned mold is made of an inorganic fiber fleece such as a glass fiber or a ceramic fiber, a synthetic fiber, a defibrated felt of a natural fiber, or the like. Bound, area density 200 to 2000 g / m 2 , thickness 10 to 200 m / m
It is molded to a degree. Further, in the present embodiment, the trimming portion 13 for cutting off is provided integrally when the upper mold 10 is formed. However, the trimming portion 13 may be embedded in the mold body 11, or may be attached to and detached from the mold body 11 by using a screw or the like. It may be freely attached. Further, the push-off trimming portion 13 may be provided in either the upper die or the lower die in correspondence with the position of a punched hole formed at a desired position inside the contour of the molded body. Further, the forming step and the punching step may be performed simultaneously or continuously, but a large number of formed bodies are manufactured in advance by performing only the forming step continuously, and thereafter, the punching step is performed continuously. You may.

In FIG. 0, a bolt bolt groove for extraction 42 having a diameter larger than that of the bolt screw groove 14 for mounting is provided coaxially with the bolt screw groove 14 for mounting. The mounting bolt 50 is provided in the extraction bolt screw groove 4.
2 is screwed into the mounting bolt thread groove 14 of the upper die 10 by passing through the groove 2. The head 50a of the mounting bolt 50 is embedded in a space 43 provided below the bolt bolt groove 42 for extraction.

From the mounting state shown in FIG. 2, the mounting bolt 50 is loosened to be removed from the mounting bolt screw groove 14, and then, as shown in FIG. By tightening, the tip end of the extraction bolt 60 hits the mold body 11, and by further tightening, the push-off trimming section 40 can be separated from the mold body 11. That is, since the extraction bolt 60 contacts the mold main body 11 and does not move forward any more, the trimming section 40 for cutting off is separated from the mold main body 11 with the tightening operation of the extraction bolt 60.

Does not come into contact with the mounting bolts 50 and is not buffered. In addition, the cutting waste and the thermosetting resin binder at the time of molding soften and enter into a gap of about 0.1 mm formed between the mold body 11 and the trimming part 40 for press-cutting, and the two members are firmly bonded to each other. Regardless, as described above, since the separating force due to the tightening force of the extraction bolt 60 is strong, these can be easily separated.

When the spacer 70 is mounted, the mounting bolt 50 provided on the mold main body 11 and the mounting bolt screw groove 14 are provided together with the trimming portion 40 for pushing and cutting the spacer 70.
To the mold main body 11 such that the head 50a of the mounting bolt 50 is completely embedded. FIG. 4 shows a state in which the spacer 70 is mounted in this manner.
As shown in the figure, the spacer 70 is provided between the mold main body 11 and the trimming section 40 for cutting off. At this time,
The spacer 70 is provided with a hole 71 having a larger diameter than the mounting bolt screw groove 14. The hole 71 is preferably provided with the same diameter as the extraction bolt screw groove 42 and coaxially with the extraction bolt screw groove 42 in the installed state. Here, the spacer 70 uses a special steel material having a thickness of about 0.1 to 1 mm. In the present embodiment, one spacer has been described, but a plurality of thin spacers may be used. The spacer may be formed in a ring shape or a frame shape, for example.
