Description

[Detailed explanation of the idea] This invention relates to a molding device.

Conventionally, a cement tile 2 with nail holes 1 as shown in FIG. 1 has been made using a dry roll forming machine 3 as shown in FIG.

That is, a molding material 4 mainly composed of a hydraulic inorganic binder such as cement is caused to flow down from a hopper 5 onto a lower mold 6 (attached to a pallet conveyor 7) that moves in the direction of arrow A. By moving the lower forming die 6 in the direction of arrow A and rotating the forming roll 8 in the direction of arrow B, the compressed material is formed on the lower forming die 6, and the forming die 9 prevents the molded product 10 from lifting up and flattens the surface. smooth.

Then, this molded product 10 is cut into each receiving mold 6 by a cutting device 12 that moves the cutting blade 11 up and down while moving in synchronization with the movement of the lower mold 6, and the cut molded product 10 is made with nail holes. After forming a nail hole with the nail hole forming nail 14 of the applying device 13, color ply and emulsion clear coating are applied, followed by curing and hardening.

In this case, the cutting device 12 includes a cylinder 16 having an actuation rod 15 that can be raised and lowered, a base plate 17 provided at the tip of the actuation rod 15, and a presser foot 19 provided to the base plate 17 via a compression spring 18. This presser foot 17 has its upper end fixed to the substrate 17.
The cutting blade 11 is slidably disposed within the mounting portion 20 of the
It consists of

During cutting, the entire cutting device 12 moves at the same speed as the lower mold 6, and its operating rod 15 descends to press down the surface of the molded product 10 with the presser foot 19. From this state, the operating rod 1
5 descends against the compression spring 18, and as a result, the cutting blade 11 slides downward within the mounting portion 20 of the presser foot 19, and the presser foot 1
The protruding molded product 10 is cut from 9.

At the end of cutting, the actuating rod 15 rises, and the cutting blade 11 slides upward in the attachment part 20 of the presser foot 19 and is housed in the presser foot 20 (until this point, the presser foot 19 has been moved by the compression spring 18). (continues to press the surface of the molded product 10), then the presser foot 19 housing the cutting blade 11 rises, and the entire cutting device 12 returns to its original position.

This operation is repeated to cut the molded product 10 together with the lower die 6.

As the nail hole forming device 13 (which moves in synchronization with the lower die), there is used one in which a nail 14 is provided at the tip of an operating rod 22 of a cylinder 21, as shown in FIG.

Further, as shown in FIG. 4, a presser foot 24 having a presser surface 23 whose shape matches the surface shape of the molded product 10 and a nail 25 provided on the presser surface 23 is also used. 22 or the presser foot 24 lowers the nail 14.
25 is pushed into the molded product 10 to form a nail hole.

However, the ones in Figures 3 and 4 do not have a presser foot that operates like the presser foot 19 in Figure 2, so when forming a nail hole, the end of the molded product near the nail hole forming position loses its shape. or
Cracks frequently appeared near the nail holes.

Therefore, a nail hole forming device 27 having a presser foot 26 as shown in FIG. 5 was devised.

That is, this nail hole forming device 27 has the same configuration as the cutting device 12 shown in FIG. Presser foot 26 provided via compression spring 31
, a nail 33 whose upper end is fixed to the base plate 30 and is slidably disposed in the mounting hole 32 of the presser foot 26 , and a frame body (which functions to guide the lifting and lowering of the presser foot 26 and prevent the compression spring 31 from popping out). (not shown for convenience), and operates in the same manner as the cutting device 12 in FIG. 2 to form a nail hole.

According to this nail hole forming device 27, deformation of the molded product when the nail 33 is removed can be prevented by the presser foot 26;
When the molded product was pushed in, the pressure caused the material forming the molded product to be pushed laterally, causing cracks to occur from around the nail hole to the ends of the molded product, causing it to lose its shape.

This idea was developed in view of the above circumstances, and consists of a forming roll, a forming lower die that faces the forming roll with a predetermined gap and moves continuously in one direction, and a mold for the forming lower die. Equipped with a cutting blade with a presser that moves forward and backward with respect to the surface and a seal for forming a presser nail hole, the molding material is compacted between the forming roll and the lower molding mold and molded onto the lower molding mold. This is a molding device that continuously forms a molded product into an appropriate size using a cutting blade with a waist press and an enclosure for providing nail holes while pressing, and also forms nail holes in the molded product. The gist of the present invention is a forming device characterized in that a blade and a presser nail hole forming seal are brought close to each other and both are operated at the same time.

In other words, by bringing the cutting blade with the presser foot and the presser nail hole-forming enclosure close to each other and operating both at the same time, the constituent materials of the molded product are forced laterally when the lamp body is pushed into the molded product. is blocked by the cutting blade, so
When forming a nail hole, cracks or deformation around the nail hole can be prevented.

Further, since the molded product is prevented from deforming when the lamp body is removed, the deformation and cracking caused by forming nail holes can be almost completely prevented.

Next, this invention will be explained in detail based on examples.

FIG. 6 is a perspective view of a main part of a nail hole forming device according to an embodiment of the invention, and FIG. 7 is a cross-sectional view taken along line 1--2.

That is, this nail hole forming device is similar to the presser foot 2 of the device shown in FIG.
6, a cutting blade attachment part 34 is provided as shown in FIG.
0, and a cutout hole (7th hole) inside the presser foot 26.
A connecting rod 37 is disposed therein, and the cutting blade (FIG. 6) 35 and the nail 33 are connected by this connecting rod 37.

The cutout hole 36 is sized to allow the connecting rod 37 to move up and down.

The other parts are the same as the nail hole forming device shown in Figure 5.
Identical parts are given the same reference numerals.

This nail hole forming device moves in synchronization with the lower mold (Fig. 2) 6, cuts the molded product 10 and drills nail holes at the same time, and returns to its original position, so that it is always in operation. is positioned above the molded product 10.

Then, when the intended cutting position of the molded product 10 comes directly below the cutting blade 35 of this device, the operation starts and the operating rod 28 is lowered.

When the actuating rod 28 descends and the lower surface of the presser foot 26 contacts the surface of the molded product 10, and when the actuator rod 28 further descends from that state, the compression spring 31 begins to contract, and the presser foot 26 presses down the surface of the molded product 10. The cutting blade 35 and the nail 33 are placed on the actuating rod 28, slide within the mounting portions 32, 34 of the presser foot 26, and protrude from the presser foot 26 to simultaneously cut the molded product 10 and form the nail hole.

During this cutting and nail hole formation, the presser foot 26 is in effect, and the cutting blade 35 prevents the material from moving during the nail hole formation, so that cracks and deformation around the nail hole do not occur, and the cut portion No cracks or deformation occur in the vicinity.

After cutting and nail hole formation are completed, the cutting blade 35 and the nail 33 rise as the operating rod 28 rises.

At this time, the presser foot 26 continues to press the surface of the molded product 10 by the action of the compression spring 31 until the cutting blade 35 and the nail 33 are removed from the molded product 10, so that the surface of the molded product 10 does not lose its shape. do not have.

Then, as the operating rod 28 rises, the presser foot 26, cutting blade 35, and nail 33 return to their initial states, and the nail hole forming device moves in the opposite direction to the lower mold 6 and returns to the initial position, starting the next scheduled cutting. Wait for the position to arrive.

In this way, this nail hole forming device includes the cutting blade 35,
In addition, since the cutting blade 35 is operated at the same time as the nail 33, when forming the nail hole, no cracks or deformation occur around the nail hole in the molded product 10, and no cracks or deformation occur near the cut portion. It never occurs.

In addition, since cutting is performed at the same time as nail hole formation, two operations can be performed in one process, increasing manufacturing efficiency.

Note that in the nail hole forming device described above, both the cutting blade 35 and the nail 33 are provided on the presser foot 26, but the cutting blade 35 and the nail 33 are separated and each is provided with a presser foot. The blade and nail may be placed close to each other and operated simultaneously.

Furthermore, instead of providing the cutting blade 35 and the nail 33 on the base plate 30, they may be directly attached to a reciprocating means such as the cylinder 29.

Note that the number of nails is not limited at all.

As described above, the molding device of this invention includes a molding roll,
A lower mold that faces this molding roll with a predetermined gap and moves continuously in one direction, and a cutting blade with a presser and a presser that are provided to move forward and backward with respect to the mold surface of the lower mold. Equipped with an enclosure for forming nail holes, the molding material is compacted between the forming roll and the lower molding mold to continuously form a molded product on the lower molding mold, and a cutting blade with a presser and a presser for driving nail holes are formed. This is a molding device that cuts the molded product into an appropriate size using an enclosure and also forms a nail hole in the molded product, and the cutting blade with a presser and the enclosure for providing a presser nail hole are brought close to each other, and both are connected. Since they are operated at the same time, it is possible to almost prevent deformation and cracks from occurring when forming a nail hole.

Furthermore, it is possible to naturally prevent deformation and the occurrence of cracks in the vicinity of the cut portion.
