DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a device for embedding an accessory mounting bracket in a washroom counter.

(b) Conventional technology In the past, synthetic resin material was poured into a front mold with the surface of the product facing downward, and a back mold was placed above it to mold the same material.
There is a manufacturing method for washstand counters that is hardened, and in order to embed the mounting bracket (b) for attaching accessories such as a washbasin on the back side of the counter, a back mold is used as shown in Figure 5. Temporarily attach the same metal fitting (b) to the bottom surface of (a) with double-sided adhesive tape, and place the same back mold (a) on the top surface of the uncured synthetic resin material poured into the front mold (C). , the same metal fittings (
The manufacturing method used was to press b) into a synthetic resin material, wait for the material to harden, and then create a washstand counter with accessory mounting brackets embedded.

(c) Problems to be solved by the invention However, since the accessory mounting bracket is temporarily attached to the bottom surface of the back mold, the work must be done facing upwards when the back mold is suspended, which makes the work difficult. It is inconsistent and tends to be unreliable when worn temporarily. In addition, the back mold (a) is attached to the front mold (C).
It is easy for the mold to shift when placing it, and the position is fixed and separated when temporarily attached.

(d) Means for Solving the Problems In this invention, in order to mold the synthetic resin material injected into the front mold, in a molding device for a washstand counter configured to make the back mold fit together, the front mold and the back mold are combined. An accessory that has a protrusion that should fit into the recess of the stationary mold placed at the desired position of the front mold on the alignment plate interposed between the two, and is buried in the back of the product at the desired position of the same alignment plate. To provide a device for embedding an accessory mounting bracket in a washroom counter by temporarily attaching the mounting bracket.

(E) Function According to the present invention, the positioning plate is separate from the front mold and the back mold, and when temporarily attaching the accessory mounting bracket, only the positioning plate is turned upside down and the work is performed facing downward. Attach the accessory mounting bracket temporarily, and during the molding process, turn the positioning plate upside down and attach the accessory mounting bracket temporarily, and then turn it over again to insert the recessed part of the front mold into which the synthetic resin material was injected. While inserting the convex part of the alignment plate into the plate, press-fit the accessory mounting bracket temporarily attached to the bottom surface of the alignment plate into the surface of the synthetic resin material in the table mold and embed it in the same material. The back mold is placed to form a mold that is integrated with the front mold, and the synthetic resin material inside is cured to produce a molded product.

(f) Effects According to the present invention, only the positioning plate can be turned over, and accessory mounting brackets can be temporarily attached while facing downward, making the work much easier than the above-mentioned upward facing work. In addition, the temporarily attached position of the accessory mounting bracket can be accurately and reliably regardless of the misalignment.

Therefore, since the mounting position of the accessory mounting bracket becomes accurate, the mounting of the accessory to the molded product becomes accurate and easy.

(G) Example An example of the present invention will be described in detail based on the drawings. In Figure 1, (^) shows a manufacturing apparatus for an artificial marble sink counter (B) made of synthetic resin. (^) is a front mold (1) with an opening on the F side and a back mold (2) with the longitudinal direction in the left-right direction.
and an alignment plate (3).

The table mold (1) is approximately rectangular with the longitudinal direction in the left and right direction, and has a shallow box shape with an opening on the top surface, and a table mold (13) is placed approximately in the center. A recess (6) is formed into which the projection (5) of the back mold (2) is inserted.

The back mold (2) is approximately plate-shaped and has a planar shape that matches the top opening of the front mold (1), and the bottom surface of the back mold (2) is the upper surface of the synthetic resin material injected into the front mold. In addition to flattening the resin material, the upper surface of the synthetic resin material is coated to prevent curing from being inhibited by air.

The positioning plate (3) has a substantially rectangular plate shape, and is fitted into a recess (6) provided in the placing mold (13) on the surface mold (1) approximately at the center of the positioning plate (3). A convex portion (5) is formed for positioning the alignment plate (3), and a temporary mounting position for an accessory mounting bracket (7) described later is provided on the bottom surface. ) marks to ensure accurate temporary fitting (
8), and the accessory mounting bracket (7) is temporarily attached using double-sided adhesive tape or the like to match the mark (8).

In particular, the alignment plate (3) is accurately positioned relative to the table mold (1) by fitting the mold recess (6) on the table mold (1) with the convex portion (5) L of the positioning plate (3). The position of the mark (8) is extremely accurate.

Alternatively, a strong permanent magnet (9) may be fixed at the temporary attachment position of the alignment plate (3), and the accessory mounting bracket (7) may be attracted by this magnetic force.

The accessory metal fittings (7) are as shown in Figures 1 and 3,
A reduced diameter part (10) is formed at one end, and an enlarged diameter part (11) is formed at the other end.
When it is formed and embedded in a molded product, it cannot be removed.

In addition, a female screw is provided for screwing in the screw used when attaching the washbasin as an accessory, and the reduced diameter part (10) is positioned on the positioning plate (3). There is. The embodiment of the present invention is configured as described above,
In manufacturing the artificial marble, first, the recess (6) formed in the placing mold (13) on the table mold (1) is covered with a plate or the like.

On the other hand, turn the alignment plate (3) upside down and temporarily attach the reduced diameter part (10) of the accessory mounting bracket (7) to the mark (8) marked at the temporary attaching position using double-sided adhesive tape, etc. I'll keep it.

Furthermore, in the case where a strong permanent magnet (9) is fixedly installed at the temporary attachment position of the alignment plate (3), the accessory mounting bracket (7) is attracted by this magnetic force.

In addition, a thermosetting synthetic resin material for the base material mixed with a hardening agent is poured into a separately provided raw material container, and a colored synthetic resin material for pattern appearance is mixed into the same material, and the raw material container is At the same time, lift it up with a lift or chain block, tilt the raw material container, and pour it into the mold (1).

Once the synthetic resin material has been injected, remove the plate that covered the recess (6), turn the positioning plate (3) over again, and attach the positioning protrusion (5) and temporarily attached accessory mounting bracket (7). with the convex part (5) facing downward and place the mold (1) on the surface mold (1).
While fitting the accessory mounting bracket (7) into the recess (6) of 3), press fit the temporarily attached accessory mounting bracket (7) from the upper surface of the synthetic resin material injected into the table mold (1). Embedded in synthetic resin material.

Next, the back mold (2) is placed on the front mold (1) to form an integrated mold, and the synthetic resin material inside is heated and cured, and after hardening, it is dehardened to form a product. do.

As mentioned above, the positioning plate (3) is separate from the front mold (1) and the back mold (2), and since the positioning plate (3) can be turned over, it is possible to remove the accessories when working downward. The mounting bracket (7) can be temporarily attached, and during molding work,
Flip the positioning plate (3), on which the accessory mounting bracket (7) has been temporarily attached, again and insert it into the recess (6) of the stationary mold on the top mold (1).
Then, while fitting the convex part (5) of the alignment plate (3), attach the accessory mounting bracket (7) temporarily attached to the lower surface of the alignment plate (3) to the synthetic resin in the table mold (1). Since it can be press-fitted into the surface of the material and buried in the same material, it is much easier to perform the work compared to the conventional upward work.
The temporary attachment position of the accessory mounting bracket (7) is now accurate, and
Temporary attachment is also ensured, the accessory mounting bracket (7) is buried in an accurate position, and the synthetic resin material is prevented from shifting or falling off during curing.

FIG. 4 is a perspective view from diagonally below the washstand counter (B) manufactured as described above, and the back side of the counter (B) has a recess (1) with the same shape as the alignment plate (3).
2) is formed, but since it is on the back side, it does not affect the appearance of the product at all, but rather the concave part (12)
If the shape of the recess (12) is matched with the outer edge shape of the attachment surface of the accessory, the recess (12) can be used for positioning the accessory, and the accessory can be mounted more accurately.

In addition, if a strong permanent magnet (9) is fixed at the temporary attachment position of the alignment plate (3), this magnetic force will attract the accessory mounting bracket (7), so auxiliary materials such as double-sided tape can be used. The metal crystal mounting bracket (7) can be attached easily while the synthetic resin material is curing because it is strongly attracted by the magnetic force of a strong permanent magnet. This will prevent it from slipping or falling off.

As mentioned above, it is not only easier to temporarily attach the accessory mounting bracket (7) and improve work efficiency, but also because the buried position of the accessory mounting bracket (7) on the back of the product is accurate. When assembling the product's washstand counter, accessories such as the washbasin can be installed in accurate positions, which improves the quality of the product and also makes the assembly process easier.
