The outer frame body and the base of the heater block are detachably connected to each other.

(Function) This invention fastens the lower mold body to the upper surface of the heater block, and connects the outer frame body and the base of the heater block to both the first and second connecting shafts.
A lower mold device consisting mainly of an outer frame, a heater block, and a lower mold main body is integrated in advance by being connected by a collar shaft and a connecting body. To assemble the lower mold device when changing the setup of the lower mold device to the press molding machine, move the integrated lower mold device as described above to a predetermined position on the upper surface of the pad of the press bed in the press molding machine. At this point, the heater block is fastened to the upper surface of this pad, and then the base of the heater block and the outer frame are separated, and the process is completed by fastening the outer frame to the elevating frame guide of the press molding machine.

(Example) An example of this invention will be described below with reference to the drawings.

In FIG. 1, which shows a vertical section of the lower mold device for tile forming, and FIG.
The outer frame body 1 is tightened by fixing bolts B1 to
, a heater block 4 which is fastened to the upper surface of a bud D fixed to a press bed C of the press molding machine via a base 2 and a heat insulating plate 3; and a heater block 4 which is fitted within the frame of the outer frame 1 and It is constructed as a main body with a lower mold body 6 which is fastened to the upper surface of the mold body 4 via a supplementary piece 5.

A vertical first connecting shaft 10 is integrally fixed with the outer frame 1 at a predetermined position on the lower surface of the outer frame 1, while a first connecting shaft 10 is fixed on the upper surface of the base 2 of the heater block 4.
A second vertical connection shaft 11 is fixed integrally with the base 2 at a position facing the connection shaft 10 .

A flange portion 12 that abuts the lower end surface of the first connecting shaft 10 in a separable manner is screwed into the upper outer periphery of the second connecting shaft 11 so as to be movable forward and backward. That is, the collar shaft 12
is formed into a cylindrical shape with a closed upper end and an open lower end, and has a female thread 1 in its center hole that is screwed into a male thread 11a formed on the outer periphery of the upper half of the second connecting shaft 11.
2a is formed.

Further, a cap nut-shaped connecting body 13 is fitted onto the outer periphery of the second connecting shaft 11 so as to be movable in the axial direction. At the bottom of this body 13, an engaging part 13a is formed which engages with the lower end surface of the collar shaft 12 so as to be able to come into contact with and separate from it.
A male thread 10 formed on the lower outer periphery of the connecting shaft 10 of
A female thread 13b is formed to be screwed into the part a. Then, both the first and second connecting shafts 10 and 11 are connected to the collar shaft 1.
2 and the connecting body 13, the outer frame 1 and the base 2 of the heater block 4 are removably connected.

On the other hand, at a predetermined position on the upper surface of the pad D of the press bed G, as shown in FIG. Ru. A predetermined number of guide rollers 16 are rotatably supported on both sides of the roller support frame 15, and the upper end of the outer peripheral surface of each guide roller 16 is connected to a pad D.
It is arranged so that it can protrude from the upper surface by a predetermined amount.

In the lower die device configured as described above,
As shown in FIG. 1, the lower die main body 6 is fastened to the upper surface of the heater block 4 via the replenishment piece 5 and with a tightening bolt 17. Also, the outer frame 1 and the lower die main body 6 are fitted together, and the first connecting shaft 10 of the outer frame 1 and the second connecting shaft 11 of the base 2 of the heater block 4 are connected to the collar shaft 12 and the connecting body. 13 to integrate the outer frame 1, heater block 4, base 2, and lower mold main body 6, and prepare in advance for changing the lower mold apparatus.

The lower mold device is assembled in the tile press molding machine in the following manner when changing the lower mold device.

First, as shown in FIG. 2, the lifting frame guide A of the press molding machine is lowered to the lower end, and the support part 1 of the roller groove 14 of the pad D in the press bed C is
A roller support frame 15 equipped with a guide roller 16 is placed on 4a.

Thereafter, the base 2 of the heater block 4 in the previously integrated lower die device is slid to a predetermined position by the guide roller 16 protruding from the upper surface of the butt D of the press bed C. Here, raise the elevating frame guide A to the upper end and move the base 2 of the heater block 4 onto the guide roller 16.
The roller support frame 15 provided with the guide roller 16 is removed from the roller groove 14 of the pad D in a state where it is raised from above.

Next, as shown in FIG. 3, the elevator frame guide A is lowered to the lowering end, and the base 2 of the heater block 4 is placed on the upper surface of the pad D. Then, while fastening the heater block 4 together with its base 2 to the upper surface of the pad D with fixing bolts B2, the connecting body 13 is separated from the first connecting shaft 10 of the outer frame body 1. This connecting body 13 is lowered along the second connecting shaft 11 of the base 2. At this time, the outer frame 1 is supported with the lower end surface of the first connecting shaft 10 in contact with the upper end surface of the flange shaft 12 that is threaded onto the second connecting shaft 11 of the base 2. .

Thereafter, as shown in FIG. 4 again, with the lifting frame guide A raised to the rising end and the outer frame 1 and the base 2 of the heater block 4 separated, , the outer frame 1 is fixed by the fixing bolts B1, while the second
By rotating the flange shaft 12 in a predetermined direction with respect to the connecting shaft 11 and lowering the flange shaft 12, the work of assembling the lower die device to the tile press molding machine is completed.

As shown by the chain line in FIG. 4, the upper mold E is lowered to the lower mold body 6 of the lower mold device assembled as described above, and after the tile is press-molded, the upper mold E is returned to its original state. rise to position. Thereafter, as shown in FIG. 5, the outer frame body 1 is lowered together with the lifting frame guide A, and the product W is taken out. When the outer frame 1 is lowered, the first and second connecting shafts 10 of the outer frame 1 are arranged so that they do not come into contact with the upper end surface of the collar shaft 12 of the second connecting shaft 11 of the base 2. The shaft lengths of the two connecting shafts 10 and 11 are set.

In addition, in the above-described embodiment, the collar shaft 12 is screwed into the tip of the second connecting shaft 11 by a screw means so as to be able to move forward and backward, but the invention is not limited to this.
For example, the collar shaft 12 may be loosely fitted into the second connecting shaft 11 so as to be movable forward and backward, and the collar shaft 12 may be removably fixed in the forward position by a pin.

Further, a connecting body 13 that is fitted into the second connecting shaft 11 so as to be movable in the axial direction and that engages with one end of the collar shaft 12 so as to be able to come into contact with and separate from the first connecting shaft 10 is connected to the first connecting shaft 10 by screw means. Although the parts are removably connected in this way, the present invention is not limited to this, and they may be removably connected using a pin or the like.

(Effect of the invention) In other words, according to this invention, unlike before,
The lower mold device, which mainly consists of the outer frame, the heater block, and the lower mold main body, is integrated in advance and moved to a predetermined position on the upper surface of the pad of the pressbed. First, the heater block is tightened to the upper surface of the pad. After that, the base of the heater block and the outer frame are separated and the outer frame is fastened to the lifting frame guide, thereby completing the work of assembling the lower die device to the press molding machine. This has the effect of shortening the time needed to change the lower mold device for the press molding machine.
