Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a husband plate with an aquarium in which a resin such as polyurethane is injected between the plate body and the aquarium and the two are integrally bonded. This invention relates to a molding device for integrally molding these two parts by injection.

Generally, a husband plate with a water tank has an open green flange for the water tank placed on the closed edge of the plate, and this flange is vertically fixed to the plate with bolts or the like to connect them as one body.

However, this has the problem that water leaks from the joint between the plate and the water tank, making it unusable for a long period of time. Therefore, the inventors of the present invention have devised a method in which a resin such as polyurethane is injected between the plate and the water tank, and the resin is cured to join the two together.

This is done by first placing a plate on the upper surface of the lower mold, and then sliding this plate so that its joining edge rests on the elastic sealing material buried in the lower mold. The water tank is placed on the elastic sealing material of the lower mold so as to face the joint end of the body, and resin is injected between the part and the plate body to bond and mold. However, when the water tank is placed on the elastic sealing material, the part of the water tank that rests on the elastic seal Murakami is small, so the water tank slips off the elastic sealing material, and the gap between the plate and the water tank becomes uneven, causing the connection. There were problems such as variations in strength and deterioration of appearance. In other words, there was a problem that the quality of the finished aquarium-equipped fish tank was not stable. The present invention has been made in view of these points, and it is an object of the present invention to provide a molding device that can produce a top plate with a water tank of stable quality.

The following explanation will be given by taking as an example a molding apparatus for a husband plate with a water tank as shown in FIG.

In the figure, reference numeral 1 denotes a base, and a lower mold base 3 that slides back and forth by a first plunger 2 is provided.

Reference numeral 4 denotes a column erected at the rear end of the base 1, and an upper mold table 6 that is moved up and down by a second plunger 5 is provided on the top of the column.

The upper die table 6 is arranged so as to face the support column 4 when the lower die table 3 moves toward the support column 4. 7, 8,
Reference numerals 9 and 10 are provided at each end of the stroke of the upper mold table 6 in the case of the lower mold table 3, or are mitt switches for stopping the movement of the upper mold table 6 at the lower mold table 3.

Reference numeral 11 denotes a lower mold provided on the upper surface of the lower mold table 6, in which an annular groove 12 is provided as shown in FIG. 3, and an elastic sealing material 13 made of a silicon tube or the like is provided.

As is clear from FIGS. 4 to 6, this elastic sealing material 13 is provided so as to protrude upward from the upper surface of the lower mold 11, and in this embodiment, it is formed into a hollow shape so that compressed air is supplied into it. It is set as. Reference numeral 14 denotes a protrusion provided on the outer short side of the elastic sealing material 13, which can be freely projected and retracted by a spring 15 as shown in FIGS.
It supports the plate 16 placed on top. Reference numeral 18 denotes an aquarium support provided at the inner corner of the elastic sealing material 13, which is supported by a spring 19 so as to be movable up and down as shown in FIGS. 4 to 6, and is made of synthetic resin or the like. .

The water tank support 18 is made to protrude above the elastic sealing material 13 so that the water tank 20 placed on the elastic sealing material of the lower mold 11 is floated above the elastic sealing material 13 and supported. . Reference numerals 21 and 22 are positioning plungers for positioning the plate 16 placed on the upper surface of the lower mold 11, and are designed to fit into a recessed hole 16a formed on the back surface of the plate 16.

A fixing plunger 23 fixes the plate 16 on the lower die, and presses and fixes the positioned plate 16 so that it does not move.

Reference numeral 24 designates an upper mold provided on the upper mold table 6, and as shown in FIGS. is formed.

27 is a resin injection device for injecting a thermosetting resin such as polyurethane, unsaturated polyester, or epoxy into the concave groove 25 of the upper mold 24 from the resin injection port 26, and the injection hose 28 is flexible. It is formed so that it can be freely inserted into the resin injection port 26 of the upper mold 24.

The operation of the above-mentioned basic construction will now be explained using FIG. 7 according to the work procedure.

First, the lower mold stand 3 is normally located in front of the base 1 as shown in FIG. 1, and the user places the plate 16 with the cutout hole upside down on the lower mold 11 thereon. Then, turn the clamp switch 30 shown in FIG.
, 22 to fix the plate 16 in place. As a result, the plate 16 is pressed onto the lower mold 11 as shown in FIG. Next, the water tank 20 is placed inside the hollowed out hole of the plate 16. At this time, the water tank 20 is supported so that the stepped part 20b of the closing edge flange part 20a is supported by the water tank support 18 provided inside the elastic sealing material 13, as shown in FIG. Layer. Thereby, the water tank 20 is held at a predetermined straightness without touching the elastic sealing material 13, and no misalignment occurs. When the battle list of the water tank 20 is completed, the user turns on the operation switch 32.

As a result, the first plunger 2 is actuated, and the lower mold stand 3 is moved toward the support column 4 side. When the lower mold table 3 moves to a predetermined position, the IJ mitt switch 7 is turned on, the second plunger 5 is activated, and the upper mold table 6 is lowered. As the upper mold table 6 descends, the upper mold 24 moves to the water tank member 2 as shown in FIG.
The water tank member 20 and the plate body 1 are moved upwardly so as to cover the gap between the water tank member 20a and the plate body 16.
6 Press onto the lower mold 11. At this time, the aquarium 20 is supported by the aquarium supporter 18 as described above.
8, so it does not move and is securely pressed against a part of the elastic sealing material 13, and the gap t (see Fig. 6) between the plate body 16 and the open twill portion 16a is always constant. becomes. That is, the aquarium 20 is always fixed at a fixed position due to the presence of the aquarium supporting odor 20. On the other hand, the lowering of the upper mold 24 causes the limit switch 10 to turn ○N, and the pressurization time setting timer 33 to start operating.

After a certain period of time has elapsed, the timer contact 33a is turned on, the second plunger 5 is activated, and the upper die 24 is raised.
During this time, the user inserts the injection hose 28 of the Western mold device 27 into the resin injection port 26 of the upper mold 24 and pours the resin for casting into the gap t between the plate 16 and the water tank member 20. When this resin hardens, the upper mold 24 rises as described above. That is, the pressurization time setting timer 33 is set to the time required for resin injection and curing of the resin as the operating time. When the casting is completed as described above and the upper mold 24 is raised, the limit switch 9 is turned on, the lower mold return relay 34 is activated, and its relay contact 34a is turned on.

This causes the first plunger 2 to operate and the lower die 11 to return to its original position. When the limit switch 8 is pressed and the normally closed contact 8a is opened, the normally open contact 8a is opened.
b is closed to operate the relay 35, and its relay contact 3
5a is turned off to complete one casting session. The resin molded in this manner is cured to integrally connect the plate 16 and the water tank 20, thereby providing a husband plate with a water tank as shown in FIG.

Note that 36 in the figure is resin. As is clear from the description of the embodiments above, according to the molding device of the present invention, the aquarium can be installed at a certain position due to the presence of the aquarium supporting odor that can be moved up and down, and when the aquarium is pressed. Also, the water tank can be held so that it does not move due to deformation of the elastic sealing material, and the gap between the plate and the water tank can be kept constant at all times.

Therefore, the resin injected into the gap between the plate and the water tank and cured always exhibits a constant bonding strength and bonding strength, resulting in stable quality and improved appearance, which has great industrial value. There is something.
