Description

[Detailed explanation of the idea] The present invention relates to a mold for forming a lower housing of a dishwasher.

Conventionally, the lower housing of this type of dishwasher has been formed by forming a frame structure of regular threaded steel, to which an outer plate, such as a stainless steel plate, is stretched and welded, and the legs are screwed or welded. However, it has drawbacks such as a large number of parts, making the assembly extremely complicated, and when stainless steel plates are used, the cost is extremely high.

The object of the present invention is to eliminate the above-mentioned drawbacks and provide a mold for molding a lower housing of a dishwasher, in which the lower housing can be molded from glass woven reinforced plastic.

Next, the main idea will be explained with reference to the drawings.

As shown in FIG. 1, the mold for forming the lower housing made of glass fiber reinforced plastic according to the present invention is the front mold 1. Rear type 2
．． Upper mold 3. It is equipped with a bottom mold 4 and a pair of pattern molds 5.

The front mold 1 is joined to the rear mold 2 at the center of the side surface while sandwiching the pattern mold 5, and has coupling protrusions 6 and 7 that protrude outward, respectively.
The front mold 1 and the rear mold 2 are provided with flanges 8 and 9 extending horizontally outward at the upper and lower ends of their respective end faces to receive the pattern 5 on the side surface. Fixing flanges 12 are protruded from the vertical edges of the notches 10 and 11 to be joined and connected to joining flanges 13 that protrude outward from both side edges of the pattern 5.

On the other hand, the previous type 1. The pattern mold 5 fixed between the rear molds 2 is attached to the molding portions 14 of the front mold 1 and the rear mold 2 on the sides that are joined and connected to each other.
．． It has a contoured head 16 which projects inwardly with respect to the plane containing 15.

The upper mold 3 has flanges 8 and 9 on the upper part of the front mold 1 and the rear mold 2.
A large window is provided so that both ends are joined and connected, and the peripheral edge is close to the upper edge of the front mold 1 and rear mold 2 so that work can be performed on the internal molding head from above. 1
7 is drilled.

The bottom mold 4 is a flange 8 at the bottom of the front mold 1 and rear mold 2.
, 9 so that both ends are joined and connected.

Incidentally, each of the molds 1 to 5 is appropriately provided so as to form a predetermined uneven portion, etc. on the molded product, that is, the lower housing.

For example, as shown in FIGS. 2 to 4, the front mold 1 includes a recess 18 in which an operation panel is disposed, and a groove 19 in which a removable cover can be attached for inspecting the built-in device.
It is formed to have an opening 20 surrounding it and a recessed part 21 for accommodating a built-in cock operating tool such as piping,
The molded product 16 of the pattern mold 5 is formed, for example, as a serrated surface on the molded product.

In particular, the bottom mold 4 has an expanded leg section 24 so that the leg section 23 can be molded into the molded product, and the leg section 24 is equipped with a floor adjustment screw 25 or the same screw thread as the leg section 24. A screw having a diameter is screwed inward and protrudes, and the floor surface adjustment screw 25 is provided so that it can be screwed in immediately when the molded product is finished.

Furthermore, the method of using the mold for molding the lower housing of the present invention will be described in detail.

The front mold 1 and the rear mold 2 are connected with the pattern mold 5 sandwiched between them, and the pattern mold 5 is also connected, and a bottom mold 4 and an upper mold 3 are further connected to this combined body to complete a molding mold.

Wax is applied to the completed molding mold from the window 17 of the upper mold 3 so that the molded product can be easily peeled off, a polishing agent is applied to give gloss to the surface of the molded product, and a sol-like plastic is applied. Then, glass fibers are stretched as appropriate, and sol-like plastic is again applied and hardened.

After the plastic has hardened, the respective molds are removed generally horizontally outward.

At this time, the molding surface 16 of the pattern mold 5 protrudes inward and undulates the plane containing the molding surfaces 14 and 15 of the front mold 1 and the rear mold 2 on the sides to be joined and connected to each other, thereby forming a serrated surface. Although it is configured to do so, there is less friction when cutting out the front mold 1 and the rear mold 2, and the mold cutting of the front mold 1 and the rear mold 2 becomes extremely easy.

In addition, at the joint between the front mold 1 and the rear mold 2, a so-called seam-like mark is left on the side surface of the molded product during molding, but for example, it is only on the top and bottom excluding the serrated surface 22, and it is difficult to remove or repair it. becomes extremely concise.

In addition, when the surface of the molded product is glossed, slight irregularities that occur on the molded product are likely to be noticeable, but by forming an uneven surface such as the serrated surface 22, this can be camouflaged.

According to the mold for molding the lower housing of a dishwasher configured as described above, the number of A0 parts can be greatly reduced, the lower housing is easy to assemble, and is made of lightweight and inexpensive glass fiber reinforced plastic. can be provided.

b. It is easy to cut out the mold and the surface of the molded product can be finished beautifully.

It is possible to camouflage the unevenness that occurs in the C0 molded product.

It has such remarkable practical effects.
