Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a base for a washing machine, and in particular, a method for manufacturing a base for a washing machine, and in particular a method for manufacturing a base for a washing machine by combining a plurality of molds. The present invention relates to a method of manufacturing a washing machine base using the method.

Generally, the bases of washing machines for export and those for domestic use are formed with different specifications. In other words, it is necessary to make the height of the washing machine base for export as low as possible in order to load it into a container, and for this reason, the legs of the base that support the leg wheels are removed during the molding of the base. Either as a set or by molding the legs separately from the base. Then, the legs, which are set or separately molded, are removed from the base at the site and attached to the base at positions corresponding to the legs. For example, FIG. 1 shows a base formed by setting, and FIG. 2 is a sectional view thereof. In the figure, 10 indicates a base, and 12
indicates a leg attachment part, 14 is a leg attachment hole, and 16 is a leg attachment hole.
indicates the leg to be removed. Base 10
is loaded into a container in the shape shown in FIG. 2, and the legs 16 are removed from the base 10 at the site.
The claw 18 is inserted into the hole 14 and locked, and the leg portion 16 is assembled at a position corresponding to the leg portion of the base 10, as shown in FIG.

On the other hand, in domestic washing machines, there is no need to consider such transportation problems, and it is preferable that the legs 16 of the base 10 be provided in advance at positions corresponding to the legs of the base 10. For example, the base 10 shown in FIG.
In this case, the leg portions 16 are integrally molded when the base 10 is molded, and domestic washing machines are transported in this final shape. Therefore, the base of washing machines for export, which requires the legs to be set or molded separately, and the base of washing machines for domestic use, which can be integrally molded, are manufactured using a different mold. Therefore, there is a disadvantage that the manufacturing cost of the base of the washing machine increases.

Furthermore, if the molds for washing machines for export shown in Figures 1 to 3 are used to make the base of washing machines for domestic use, the legs 16 are made in the factory in the case of washing machines for domestic use. It will be assembled in the appropriate position, packed and shipped. Therefore, in the process of manufacturing washing machines for domestic use that utilizes the mold for the base of washing machines for export, the number of assembly steps will increase, and the assembled legs 16 will not have the claws 18, etc. Since it is secured to the base 10 by a screw, great care must be taken during packaging and transportation. That is, since the legs 16 are attached to the base 10 only with the claws 18,
When packing, consideration must be given to providing a cushioning material or the like on the receiving portion of the base 10 so that a large load is not applied to the claw 18 portion during transportation.

The present invention has been made in view of these circumstances, and allows the legs of the base to be set and removed in the case of washing machines for export, and allows the legs to be integrally molded in the base of washing machines for domestic use. The purpose of this paper is to propose a method for manufacturing washing machine legs that can

In order to achieve the above object, the present invention combines a plurality of molds to form a resin molding mold for the base of a washing machine, and uses this resin molding mold to manufacture the base of the washing machine. In the method, a mold for forming a leg portion supporting a leg ring provided at a corner of a base and a mold for forming a leg attachment portion to which the leg portion can be attached are configured to be mutually interchangeable. When integrally molding the legs, place the molding mold for the legs at the position corresponding to the legs, and when setting the legs, place the molding mold for the leg attachment part at the position corresponding to the legs on the base. At the same time, it is characterized in that a mold for forming the legs is disposed in the middle part of the base.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the method for manufacturing a washing machine base according to the present invention will be described in detail below with reference to the accompanying drawings.

In the base 10 shown in FIG. 4, the leg mold 20 for molding the leg 16 and the leg mounting mold 22 for molding the leg attachment part are mutually recombined in a mold combination not shown. configured to be possible. In the embodiment shown in FIG. 4, a case is shown in which the base of a domestic washing machine is manufactured, and the leg mold 20 is arranged at a position corresponding to the leg of the base 10, and the leg mounting mold 20 is disposed at a position corresponding to the leg of the base 10. 22 is arranged at an intermediate position of the base 10. In the base of a washing machine for domestic use, the legs 16 are integrally molded with the base 10, so there is no need for a leg attachment part, and the runner part 24 stops the flow of resin, so the leg attachment metal The mold 22 is configured so that the resin does not flow. When resin is poured into the mold arranged in this way, the leg portion 16 is integrally molded with the base 10 as shown in FIG. 5, and the base of a domestic washing machine is manufactured.

On the other hand, when manufacturing a base for a washing machine for export, the positions of the leg molding mold 20 and the leg mounting mold 22 shown in FIG.
are arranged at positions corresponding to the legs, and a mold 20 is arranged at an intermediate position of the base 10. In this case, the resin is allowed to flow into the mold 20 from the runner section 28. When resin is injected into a mold configured in this way,
The base 10 is constructed as shown in FIG. It begins to form in the area.

As explained above, according to the washing machine base manufacturing method according to the present invention, the leg mold and the leg mounting mold can be interchanged, so the same mold can be used to create the base for the washing machine. It is possible to manufacture the base by integrally molding the parts and by setting the legs.
