Description

Technical Field

[0001] The present invention relates to the technical field of water outlet devices, and in particular to a die-cast water outlet component and a water outlet device. Background Art

[0002] As people's aesthetic tastes and demands for product quality increase, more and more products are being manufactured using metal materials. Taking faucet bodies as an example, to ensure their quality, including the quality of the interior and exterior, faucet bodies are currently typically formed using metal high-pressure casting. This involves rapidly injecting molten metal into a mold under high pressure, offering the advantages of high production efficiency and excellent casting quality. However, as people's demands for faucet body exterior design increase, the structure of faucet bodies has become increasingly complex, making it impossible to core the complex interior of the faucet body using high-pressure casting.

[0003] Invention patent application number 202311631103.3 discloses a die-cast component and its manufacturing method. While the invention discloses that the inner core is retained within the outlet arm, thereby resolving the problem of being unable to core-extract the inner structure of the outlet arm while also ensuring the wall thickness of the outlet arm, it does not. However, because a significant portion of one end of the inner core extends into the valve core cavity to secure the inner core, the following issues arise:

[0004] 1. The wall thickness of the valve core cavity is uneven;

[0005] 2. The structure of the inner core is relatively complex. It needs to be formed into two half shells through die casting and then assembled to form a closed inner cavity. The steps are cumbersome. In addition, the closed inner cavity may deform due to thermal expansion and contraction during the molding process, making it difficult to insert the tube later.

[0006] 3. After the main body is formed, a lot of material needs to be machined away, resulting in a lot of material waste. Summary of the Invention

[0007] In view of this, an object of the present invention is to provide a die-cast water outlet assembly and a water outlet device to solve the above problems.

[0008] The present invention adopts the following scheme:

[0009] The present application provides a die-cast water outlet component, comprising a main body and a water outlet portion with a bending area that are die-cast together, wherein a hollow component is provided inside the water outlet portion and is inserted before die-casting, and the hollow component is connected from head to tail, and is characterized in that the main body is provided with an inner cavity directly formed by die-casting, and the inner cavity is provided with an opening; the hollow component is connected to the inner cavity through the opening to form a channel.

[0010] Furthermore, the inner cavity is formed by the hollow component and core pulling filling during die casting.

[0011] Furthermore, the core pulling device includes a first core pulling device and a first slider slidably arranged on the first core pulling device; one end of the first slider extends into an opening at one end of the hollow component to form a closed sliding connection.

[0012] Furthermore, during die-casting, one end of the hollow component has a portion extending into the inner cavity, which is convenient for fixing and positioning by core pulling; and after molding, the hollow component extending into the inner cavity can be cut off.

[0013] Furthermore, the core pulling device includes a first core pulling device, a slanted top slidably arranged on the first core pulling device, and a second slider slidably connected to the first core pulling device and the slanted top; the second slider and the first core pulling device are used to clamp and fix the part of the hollow component extending into the inner cavity; when the slanted top is withdrawn, the second slider can be driven to move along the axial direction of the hollow component, thereby releasing the clamping state.

[0014] Furthermore, the hollow component is formed by processing a tubular profile; or is formed by splicing two die-cast or stamped parts.

[0015] Furthermore, the main body is made of a first material, and the hollow component is made of a second material; the melting point of the first material is not higher than the melting point of the second material.

[0016] Furthermore, the first material and the second material are at least one of zinc alloy, aluminum alloy, copper alloy, magnesium alloy, ceramic, stainless steel, and plastic.

[0017] Furthermore, when the first material and the second material are metal materials, the same metal material is used.

[0018] A water outlet device comprises a faucet body, wherein the faucet body is the die-cast water outlet component.

[0019] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0020] The present invention provides a die-cast water outlet assembly, comprising a body die-cast together and a water outlet with a bend. The water outlet is provided with a hollow component inserted before die-casting, the hollow component being continuous from head to tail. The body is provided with an inner cavity directly formed by die-casting, the inner cavity being provided with an opening; the hollow component is connected to the inner cavity through the opening to form a passage. Compared with the prior art, this hollow component has a hollow core and is continuous from head to tail, avoiding the need for subsequent machining of through-holes. The inner cavity is directly formed in one step by die-casting, eliminating the need for further machining and forming, significantly reducing the number of machining steps. Furthermore, this structure only forms a double-layer wall thickness within the water outlet, while the rest of the body has a single-layer wall thickness, saving material costs.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Example

[0035] Combine Figures 1 to 10 As shown, this embodiment provides a die-cast water outlet assembly, comprising a main body 2 and a water outlet portion 1 with a bending area that are die-cast together, wherein the water outlet portion 1 is provided with a hollow component 3 that is inserted before die-casting, and the hollow component 3 is connected from head to tail, and is characterized in that the main body 2 is provided with an inner cavity 7 directly formed by die-casting, and the inner cavity 7 is provided with an opening; the hollow component 3 is connected to the inner cavity 7 through the opening to form a channel.

[0036] Compared with the prior art, the inner core of the hollow component 3 is hollow and penetrates from head to tail, which avoids the need for subsequent machining of through holes; and the inner cavity is directly formed by die-casting in one step, without the need for secondary processing and molding, which greatly reduces the machining process; at the same time, the structure only forms a double-layer wall thickness in the water outlet part 1, and the other parts of the body have only a single-layer wall thickness, which greatly saves material costs.

[0037] Specifically, in the first embodiment, Figure 1 and Figure 2As shown, for the curved water outlet 1, the hollow component 3 can be formed by bending a tubular profile. The body includes a valve core cavity 6 and an inner cavity 7 disposed below the valve core cavity 6. The inner cavity 7 has an opening on its sidewall. The hollow component 3 is disposed within the water outlet 1 and communicates with the hollow component 3 through the opening to form a channel. This channel is used for direct water discharge or for water discharge through a pipe.

[0038] During the die-casting of this water outlet assembly, its inner cavity is formed by filling the hollow component 3 and the core pull. Specifically, as shown, the core pull includes a first core pull 10 and a first slider 18 slidably mounted on the first core pull 10. One end of the first slider 18 extends into an opening at one end of the hollow component 3, forming a closed sliding connection, thereby positioning and securing one end of the hollow component 3. During the die-casting of this water outlet assembly, the first slider 18 first slides a certain distance to allow it to be removed from the mold together with the first core pull 10, thereby forming the inner cavity 7.

[0039] In the second embodiment, the water outlet portion 1 of the die-cast water outlet assembly is flush with the step 4 between the valve core cavity 6 and the inner cavity 7. The hollow component 3 can also be bent and formed by a tubular profile. One end thereof has a portion extending and placed in the inner cavity 7. And after forming, the circumferential upper end of the hollow component 3 is tightly arranged thereon. The main body includes a valve core cavity 6 and an inner cavity 7 arranged below the valve core cavity 6; an opening is provided on the side wall of the inner cavity 7; the hollow component 3 is arranged in the water outlet portion 1, and is connected to the hollow component 3 through the opening to form a channel. The channel is used for direct water discharge or for water discharge through a pipe.

[0040] When the die-cast water outlet assembly is die-cast, its inner cavity is formed by the hollow component 3 and the core pulling filling. Figure 3 and Figure 4 As shown, the core pull includes a first core pull 10. During die casting, one end of the hollow component 3 is fixed and restrained by the second core pull 9 that forms the valve core cavity 6 and the first core pull 10. Specifically, the upper end of the first core pull 10 is provided with a limiting groove 19, and the lower end of the second core pull 9 is provided with a protrusion 11. The limiting groove 19 and the protrusion 11 tighten and secure one end of the hollow component 3.

[0041] In the third embodiment, the water outlet portion 1 of the die-cast water outlet assembly is placed below the step 4 between the valve core cavity 6 and the inner cavity 7. The hollow component 3 can also be bent and formed by a tubular profile. One end thereof has a portion extending and placed in the inner cavity 7. And after forming, the circumferential upper end of the hollow component 3 is tightly arranged thereon. The main body includes a valve core cavity 6 and an inner cavity 7 arranged below the valve core cavity 6; an opening is provided on the side wall of the inner cavity 7; the hollow component 3 is arranged in the water outlet portion 1, and is connected to the hollow component 3 through the opening to form a channel. The channel is used for directly discharging water or discharging water through a pipe.

[0042] When the die-cast water outlet assembly is die-cast, its inner cavity is formed by the hollow component 3 and the core pulling filling. Figure 7 As shown, the core pull includes a first core pull 10, a slanted lift 21 slidably mounted on the first core pull 10, and a second slider 22 slidably connected to the first core pull 10 and the slanted lift 21. The second slider 22 and the first core pull 10 are used to clamp and secure the portion of the hollow component 3 extending into the inner cavity 7. When the slanted lift 21 is withdrawn, it drives the second slider 22 to move along the axis of the hollow component 3, thereby releasing the clamp. Specifically, a first inclined surface is provided at the top end of the slanted lift, and a second inclined surface is provided on the side of the second slider 22, which is slidably connected to the first inclined surface. The top surface of the first core pull 10, which is adjacent to the hollow component 3, is slidably connected to the bottom surface of the second slider 22. The sliding connection can be a sliding connection between a slide groove and a slide rail, and the slide groove and the slide rail can be adapted to have a T-shaped or inverted triangle shape, which is not specifically limited here. A clamping groove is formed between the second slider 22 and the first core pull 10 to tighten and secure one end of the hollow component 3.

[0043] When the core is pulled, when the first inclined top 21 moves downward, it will drive the second slider 22 to move rightward to stay away from the right end surface of the hollow component 3, and then follow the first inclined top 21 to move downward for a large stroke to achieve the core pulling action.

[0044] Of course, it should be noted that the inner cavity 7 in the second and third embodiments refers to the chamber communicating with the hollow member 3, namely the lower chamber; in other embodiments, the inner cavity 7 may also be the upper chamber, namely the valve core chamber. The core-pulling structure is the same as in the second and third embodiments, but is applied to the upper chamber and will not be elaborated on here. The portion of the hollow member 3 extending into the inner cavity 7 can be removed after the main body is die-cast to facilitate pipe insertion and water discharge.

[0045] In the above embodiment, the other end of the hollow component 3 can be fixed by another fixing block. Similarly, one end of the fixing block 23 extends into the other end of the hollow component 3 to form a closed fixation, and then the fixing block is tightened by the mold to achieve positioning and fixation of the other end of the hollow component 3.

[0046] Furthermore, in the above embodiment, a ventilation channel communicating with the interior of the hollow component 3 is provided on the fixing block 23 to prevent the hollow component 3 from being broken or deformed due to thermal expansion and contraction.

[0047] Of course, the hollow component 3 can be set according to the shape of the inner cavity of the water outlet part 1. In other embodiments, the hollow component 3 can also be a two-piece structure that is first die-cast or stamped and then welded to form the complete hollow component 3.

[0048] As in the fourth embodiment, Figures 8 to 10 As shown, the shape of the inner cavity of the water outlet part 1 is irregular, and the hollow part 3 cannot be directly processed and formed by pipes. It can be die-casted in half and then assembled.

[0049] In this embodiment, the inner cavity 7 is a valve core cavity, and the hollow component 3 is connected to the inner cavity 7. The upper core pulling of the core pulling package (i.e., the second core pulling 9) can be slidably provided on the second inclined top 24 in the upper core pulling, and can be slidably connected to the third slider 25 on the upper core pulling and the second inclined top 24. Specifically, the sliding connection between the third slider 25, the second inclined top 24 and the upper core pulling is the same as that of the third embodiment, the difference being that the third slider 25 is provided with a protrusion 26 on the side close to the hollow component 3, which is engaged in the opening at one end of the hollow component 3 to fix and limit one end of the hollow component 3. Similarly, when the second inclined top 24 is withdrawn during core pulling, it can drive the third slider 25 to move to the right, so that the protrusion 26 is released away from the opening at one end of the hollow component 3, and then withdraws from the inner cavity 7 synchronously with the upper core pulling.

[0050] It should be noted that the step 4 also has an opening (not shown in the drawings) for connecting the water inlet pipe to the valve core, and the positioning through-hole 5 (formed by the protrusion 11) can be this opening, eliminating the need for a separate through-hole. Of course, for a thermostatic valve core, two or three openings are provided on the step 4, and the protrusion 11 is provided on the upper or lower pull-out core to match the two openings.

[0051] Furthermore, the other end of the hollow component 3 can also protrude outward to form a protruding section, which is convenient for fixing by the mold during molding. This method does not require the use of a fixing block 23 to position and fix the other end of the hollow component 3. And the protruding section can be processed before or after molding to form a connecting portion for connecting a water outlet. For example, it can be used to connect a water outlet that can produce different water splashes, or a bubbler. In this way, after the faucet body is die-cast, there is no need for excessive machining. Of course, in other embodiments, a thickened section can be provided at the water outlet of the water outlet portion 1 for installing the water outlet device after machining. This method requires machining the protruding section.

[0052] In an optional embodiment of the present invention, based on the above embodiment, the body is made of a first material, and the hollow member 3 is made of a second material; the melting point of the first material is no higher than that of the second material. Specifically, the first material is at least one of zinc alloy, aluminum alloy, copper alloy, magnesium alloy, ceramic, stainless steel, and plastic. The second material is at least one of zinc alloy, aluminum alloy, copper alloy, magnesium alloy, ceramic, stainless steel, and plastic.

[0053] Preferably, the body is injection-molded using plastic, eliminating the need for subsequent polishing of the exterior surface of the faucet body. Furthermore, the plastic body and hollow component 3, made of other materials, effectively prevent electrical corrosion. When the hollow component 3 is intended to directly flow water, it is made of copper alloy or stainless steel. When the hollow component 3 is intended to be threaded with pipes, it is made of aluminum alloy.

[0054] Preferably, when the first material is zinc alloy, the second material is also zinc alloy. This effectively prevents potential corrosion and does not pollute water during use, thus ensuring the health and safety of consumers.

[0055] The present invention also provides a water outlet device comprising the aforementioned body, wherein the upper chamber 6 of the body is provided with a valve core. The provision of the hollow component 3 enables high-pressure casting of the faucet body with a complex structure, thereby satisfying the functional requirements of the water outlet device while also ensuring the desired appearance of the faucet body.
