The present invention relates to a spout holder manufactured by a double injection method using two kinds of synthetic resin materials.

Spout holder refers to a part or element of a tube that carries a liquid such as water or oil. It usually has a curved shape in one direction. An apparatus for injecting oil into the fuel tank of a vehicle at a gas station may also be a kind of spout holder.

As such, spout holders are widely used around our lives. Hereinafter, a spout holder mounted on a sink of a household sink will be described.

Kitchens in modern apartments and villas are equipped with sinks for washing dishes. Water sinks for water supply are provided around the sinks.

Previously, the water supply facilities were only faucets and the like, but as a part of improving the value of interior props in recent years, a water supply facility having a structure as shown in FIGS. 1A and 1B is provided.

1A is a perspective view of a spout holder according to the prior art, and FIG. 1B is a schematic partial cross-sectional view of FIG. 1A.

As shown in this figure, the spout holder 110 forms an element of the water supply facility. When the water supply facility is added to the entire water supply facility, the water supply facility is mounted around the sink (not shown). ), A spout holder 110 coupled to the assembly body 101 for water supply, a pleated hose 120 coupled to the spout holder 110 to supply water in number, and a shower connected to the pleated hose 120. 130 is provided.

The assembly body 101 for water supply is equipped with a lever 103 for controlling or regulating the flow of water from the water pipe to the shower 130.

The pleated hose 120 has a pleated structure whose length is varied so that the shower 130 can be moved from the spout holder 110 to a desired position. The corrugated hose 120 is usually made of a metal material having corrosion resistance.

The spout holder 110 is an auxiliary means for mounting the shower 130. As shown, the spout holder 110 is bent to one side, that is, the shower 130 has a shape bent to one side to face the bottom surface of the sink.

The spout holder 110 forms a space for arranging the pleated hose 120 and means for connecting the shower assembly 130 and the assembly body 101 for water supply.

Cap 111 is further coupled to the top of the spout holder 110 to connect the shower 130 to the spout holder 110. The cap 111 is coupled to the spout holder 110 as a protrusion jaw 111a formed at the insertion end side thereof is fitted into the groove 110a formed at the inner wall of the spout holder 110.

On the other hand, the spout holder 110 having the above role and structure is usually manufactured by casting using a brass material, then released as a finished product by forming a plating on the outer surface, it is mounted on the sink area by the operator in the field.

By the way, the conventional spout holder 110 is made of a brass material as described above, there is a problem that not only the manufacturing cost increases but also the weight is heavy. Heavy weights can increase the overall logistics costs or cause worker safety problems at work.

In addition, since the spout holder 110 and the corrugated hose 120 are all made of metal, the spout holder 110 is moved in the process of moving the corrugated hose 120 in the spout holder 110 when the shower 130 is pulled out. To hit the inner wall of the) causing excessive noise, if there is a problem that causes the wear and damage of the corrugated hose (120).

Thus, in order to solve this noise problem, as shown in Figure 1b, there is an example in which the guide ring 112 of the synthetic resin material is mounted on the spout holder 110 to guide the movement of the pleated hose 120.

However, in this way, when the guide ring 112 is used, not only the additional cost according to the purchase of the guide ring 112, but also a separate assembly process for assembling the guide ring 112 is accompanied by a problem have.

In addition, even when the guide ring 112 is used, the area where the corrugated hose 120 is in contact with the guide ring 112 is small, so that the effect of substantially reducing noise is not known.

The object of the present invention is not only to significantly reduce the manufacturing cost, but also to reduce the weight, thereby increasing the safety and convenience of the operation, and also to the interference with the crimped hose even without using a separate guide ring as in the related art. It is possible to reduce the noise caused by, and further to provide a spout holder that can improve the durability of the corrugated hose.

The object is (a) mounting the inner tube pre-molded with synthetic resin to a pair of holders provided on the upper mold so that a pair of grooves are formed on the inner surface of the spout holder which is the final product; (b) approaching and closing the pair of left and right molds while allowing the exterior molding grooves formed on the inner surfaces of the pair of left and right molds to be disposed outside the inner tube mounted on the holder; (c) injecting a synthetic resin different from the material of the inner tube into the outer mold forming groove so that the outer mold is double-injected to the outside of the inner tube; (d) separating the mold to take out the intermediate molded article; And (e) is achieved by the method of manufacturing a spout holder, characterized in that it comprises the step of manufacturing the spout holder of the final product by plating the outer appearance except the inner tube.

Here, the inner tube may be made of modified polystyrene (MPPO, Modifide Polyphenylene Oxide) that is not substantially plated in the step (e).

The appearance may be made of ABS (Acrylonitrile Butadiene Styrene copolymer) that can be substantially plated in the step (e).

The pair of grooves may be formed to be opposite to each other in a region where the inner tube and the outer surface are in contact with each other.

After the step (e), the step of inserting the end of the cap into the spout holder and may further comprise the step of coupling the cap to the spout holder while the protrusion formed in the cap is fitted into the groove.

The object is an inner tube made of modified polystyrene (MPPO, substantially no plating); An outer tube manufactured by being double-injected to the outside of the inner tube and made of ABS (Acrylonitrile Butadiene Styrene copolymer) which is substantially plated; And a pair of grooves symmetrically formed in a region where the inner tube and the outer surface are in contact with each other.

Here, the exterior except for the inner tube may be plated independently.

The inner tube and the outer tube may have a curved shape in one direction, and the inner tube may be partially exposed from one side of the outer tube.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

Figure 2 is a side perspective view of the spout holder according to the present invention, the cap is placed in front, Figure 3 is a front perspective view of Figure 2, Figure 4 is a cross-sectional view of FIG.

Since the conventional spout holder 110 (see FIGS. 1A and 1B) described above has been manufactured as a cast-integral type of brass, manufacturing costs are high, its weight is heavy, and noise problems are caused.

However, since the spout holder 10 of the present embodiment is made of synthetic resin, all of the above problems can be solved.

First, the spout holder 10, which is the final product, will be described with reference to FIGS.

The spout holder 10 of this embodiment consists of the inner tube 20 and the exterior 30 largely. Both the inner tube 20 and the exterior 30 are made of synthetic resin, unlike the prior art. However, in relation to the plating process, the inner tube 20 and the outer case 30 are used in different materials.

When first expanding on the inner tube 20, the inner tube 20 has a bent shape in one direction. The inner tube 20 is formed as if most of it is inserted into the interior of the exterior 30, but a portion is provided to be partially exposed from any one side of the exterior 30.

Coupling portions 20a are formed on the outer surface of the exposed region of the inner tube 20 exposed from the outer appearance 30. Coupling portion 20a is utilized as a part that is combined with the water supply assembly body 101 when the spout holder 10 of the present embodiment is coupled to the water supply assembly body 101 shown in FIGS. 1A and 1B.

For reference, elaborate on modified polystyrene (MPPO). Modified polystyrene (MPPO) is also called the specific brand name NORYL. Such modified polystyrene (MPPO) is characterized as follows.

Excellent mechanical properties It is excellent and stable in stiffness, impact resistance and fatigue resistance in a wide temperature range from low temperature to near heat deformation temperature. Excellent electrical characteristics Excellent insulation, low dielectric constant, low dielectric loss tangent, and low temperature and frequency dependence make it safe for electrical applications. Excellent hot water resistance. Absorption is small. It does not hydrolyze even when it comes in contact with hot water or steam and is stable in strength. Excellent heat resistance The heat deformation temperature can be designed from 80 ° C to 165 ° C, and the degradation of physical properties due to heat treatment is small, and the thermal stability is excellent. It is flame retardant. It is self extinguishing. Because of its excellent flame retardancy, it is most suitable for the use of export electrical equipment with strict flame retardancy. Economical and lightweight. Due to the low water absorption, pre-drying is easy and the specific gravity is small, making it economically light. Excellent dimensional stability. The molding shrinkage rate is small and at the same time there is no fear of being affected by the molding conditions, so it is also suitable for the precision molding field where high dimensional accuracy is required. Good moldability Good releasability and flowability, and the molding temperature range is wide to facilitate molding.

Among these features, in particular, since modified polystyrene (MPPO) has excellent strength, when the inner tube 20 is made of modified polystyrene (MPPO), the spout holder 110 made of a conventional brass material (see FIGS. 1A and 1B). ) Or have a higher strength. Therefore, it may contribute to improving the durability of the spout holder 10.

In addition to these advantages, modified polystyrene (MPPO), which is a material of the inner tube 20, is not plated during plating because it is not conductive. In this way, if the inner tube 20 forming the inside of the spout holder 10 is not plated with a metal component and simply remains as a synthetic resin material, the contact with the corrugated hose 120 of FIGS. 1A and 1B will be described later. It can solve the noise and abrasion problem.

However, since the interior of the spout holder 10 of the present embodiment is made of unmodified polystyrene (MPPO), noise and abrasion problems are eliminated even when the guide ring 112 (see FIGS. 1A and 1B) is not mounted as in the related art. It will be possible to solve at the same time.

As shown in FIG. 4, a plurality of protrusions 20b are further formed on the outside of the inner tube 20 to securely couple to the exterior 30 during double injection. Of course, since the scope of the present invention is not limited thereto, the protrusion 20b does not necessarily need to be formed.

The exterior 30 is disposed on the outer surface of the inner tube 20 and molded. The exterior 30 also has a curved shape in one direction like the inner tube 20, and is made of synthetic resin, not brass.

However, the inner tube 20 is made of modified polystyrene (MPPO), whereas the exterior 30 is made of ABS (Acrylonitrile Butadiene Styrene copolymer). Of course, as will be described later, the exterior 30 is double-injected to the outside of the inner tube 20 by ABS, and after the double-injection, it is plated.

In the plating process, only the exterior 30 except for the inner tube 20 is plated independently. This is because, due to the material properties, ABS, which is a material of the exterior 30, may be plated, and modified polystyrene (MPPO), which is a material of the inner tube 20, may not be plated.

In this case, when only the exterior 30 located outside is independently plated, the spout holder 10, which is a substantially final product, is not distinguished from the conventional spout holder 110 (see FIGS. 1A and 1B) in appearance. do. In other words, it is difficult to visually distinguish the spout holder 10 and the conventional spout holder 110 (see FIGS. 1A and 1B) of the present embodiment unless it is heard.

More about ABS. ABS is a styrene resin composed of three components of styrene, acrylonitrile and butadiene. The method of preparing the mixture is generally a mixture (blend) of the copolymer of acrylonitrile and butadiene and the copolymer of styrene and butadiene. A mixed resin having the properties of a polymer is obtained at the same time. In general, it is known to be used as a metal substitute for automobile parts, helmets, electrical equipment parts, spinning machines, parts, etc. because of its easy processing, impact resistance, and heat resistance.

On the other hand, when the exterior 30 is double-injected to the outside of the inner tube 20 to produce a single spout holder 10, the inner circumferential surface of the outer surface 30 adjacent to the upper end of the inner tube 20 is formed symmetrically to each other A pair of grooves 40 are formed. The inner surface of the pair of grooves 40 from one end of the outer surface 30 to which the cap 11 is coupled is tapered.

As shown in FIG. 2, when the cap 11 is coupled to the outside of the spout holder 10, the pair of grooves 40 are used as a place where the projection jaw 11a formed on the cap 11 is fitted. do. If the pair of grooves 40 are not formed, the cap 11 may be loose or easily detached from the spout holder 10.

For reference, the protruding jaw 11a formed in the cap 11 shown in FIG. 2 is formed between the pair of cutouts 11b cut out around the protruding jaw 11a. The cutout 11b allows the protruding jaw 11a to retain an elastic force that is bent inwardly, so that the protruding jaw 11a formed on the cap 11 can be easily fitted into the pair of grooves 40. It becomes possible.

Therefore, the pair of grooves 40 need to be formed in the spout holder 10. Then, the process of manufacturing the spout holder 10 of the present embodiment through this configuration will be described step by step.

First, the inner tube 20 is prepared by molding in advance. As described above, the inner tube 20 is molded using unmodified polystyrene (MPPO).

Next, the inner tube 20, which is pre-formed, is fixed inside the mold to be secondly injected, and then ABS injection liquid is injected to double inject the outer tube 30 to the outside of the inner tube 20. Then, the exterior 30 may be injected to the outside of the inner tube 20.

After the double injection, it is cooled for a predetermined time. Then, the intermediate molded product (not shown) is taken out of the mold.

Next, the external spout 30 except for the inner tube 20 is plated to manufacture a spout holder 10 which is a final product. Of course, at this time, no effort is required to plate only the exterior 30. That is, as described above, when the intermediate molded product is plated as it is, due to the material characteristics, the inner tube 20 is not plated, only the exterior 30 is plated.

If the process of plating on the exterior 30 made of ABS is further described, first, etch is carried out in a chromic acid solution at about 70 degrees, and then paradium is substituted with butane of ABS with palladium (Pd) and tin (Sn). . It is then neutralized and subjected to electroless copper plating (Cu) on the substituted metal. Of course, electroless nickel plating or silver plating can also be performed as needed. Next, after copper lactate (Cu) plating, nickel plating and chromium plating may be performed.

After the plating of the exterior 30 is completed, one end of the cap 11 illustrated in FIG. 2 is inserted into the spout holder 10, and then the protruding jaw 11a formed on the cap 11 has the groove portion 40. The cap 11 may be coupled to the spout holder 10 while being inserted into the spout holder 10.

When the spout holder 10 is manufactured in this manner, the manufacturing cost can be greatly reduced and the weight can be reduced, thereby increasing the safety and convenience of the work.

In addition, even when a separate guide ring 112 (see FIGS. 1A and 1B) is not used as in the related art, noise due to interference with the corrugated hose 120 (see FIGS. 1A and 1B) may be reduced. That is, since most of the contact portion of the corrugated hose 120 (see FIGS. 1A and 1B) is an inner tube 20 made of synthetic resin, noise may be reduced. Therefore, it is possible to improve the durability of the corrugated hose 120 (see FIGS. 1A and 1B) with respect to noise and wear.

As such, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.

As described above, according to the present invention, not only can significantly reduce the manufacturing cost, but also reduce the weight, thereby increasing the safety and convenience of the work, and also crimped hose even without using a separate guide ring as in the prior art. Noise due to interference with and can be reduced, and further has the effect of improving the durability of the corrugated hose.
