Description
Technical Field
[0001] This application relates to the field of kitchen and bathroom shower head technology, and in particular to a shower head panel, a shower head water outlet mesh, and a mold for manufacturing the shower head water outlet mesh. Background Technology
[0002] Currently, the injection molding of silicone water outlet mesh for shower heads in the kitchen and bathroom industry uses a secondary encapsulation injection molding method where liquid silicone sprues are directly applied to the product surface. Different products require different sprues, making it impossible to standardize the injection mold. Utility Model Content
[0003] This application provides a shower head panel. It solves the problem in the prior art that the injection molds for molding silicone water outlet screens in shower heads cannot be standardized. The technical solution is as follows:
[0004] On one hand, a shower panel is provided, the shower panel comprising:
[0005] The back of the shower panel has multiple annular grooves distributed radially along the shower panel, and a set of hollow holes corresponding to and communicating with each of the annular grooves, with each annular groove being independently distributed;
[0006] The front of the shower panel has a strip-shaped inlet groove and a plurality of through holes that correspond one-to-one with the inlet groove and a plurality of annular grooves. The inlet groove has a blind end and an open end that are arranged opposite to each other along its extension direction. The open end is distributed in the edge area of the shower panel.
[0007] The inlet groove and multiple through holes are used to guide the liquid silicone of the molded water outlet soft rubber into the multiple annular grooves.
[0008] Optionally, the edge of the shower panel has auxiliary pouring bosses distributed at the opening end of the pouring groove. The auxiliary pouring bosses have an upper inclined surface, a supporting plane, and a lower inclined surface on the side away from the center of the shower panel. The supporting plane is connected to the upper inclined surface and the lower inclined surface, respectively, and the supporting plane is parallel to the extension direction of the pouring groove.
[0009] The angle between the upper inclined surface and the supporting plane is obtuse, and the angle between the lower inclined surface and the supporting plane is acute. The upper and lower inclined surfaces are located on the upper and lower sides of the supporting plane, respectively.
[0010] Optionally, the shower panel is a structure made of high-temperature resistant hard plastic.
[0011] Optionally, the projection of the inlet trough onto the shower head panel is U-shaped.
[0012] Optionally, each of the annular grooves may contain a set of perforated holes.
[0013] Optionally, the plurality of perforations corresponding to each annular groove are distributed along the extension direction of the annular groove.
[0014] On the other hand, a shower head water outlet net is provided, the shower head water outlet net comprising: a shower head panel and a water outlet net soft rubber fastened together, the water outlet net soft rubber being a structure formed by curing liquid silicone, and the shower head panel being any of the shower head panels given above.
[0015] Optionally, the water outlet mesh has multiple water outlet protrusions that correspond one-to-one with the hollow holes in the shower head panel. Each water outlet protrusion has a water outlet hole, and the end of each water outlet protrusion extends out from the corresponding hollow hole.
[0016] On another front, a mold for manufacturing a shower head water outlet mesh is provided, the mold having a mold core adapted to the shape of the shower head panel, a flow channel arranged side by side with the inlet groove in the shower head panel and one end connected to the opening end, an inlet column connected to the other end of the flow channel, and an inlet nozzle connected to the inlet column; the shower head water outlet mesh is any of the shower head water outlet meshes given above.
[0017] The mold's sprue nozzle, through the sprue column, introduces liquid silicone from the side into the sprue groove of the shower head panel via the flow channel.
[0018] The beneficial effects of the technical solutions provided in this application include at least the following:
[0019] By incorporating a sprue groove within the showerhead panel, multiple independent annular groove areas used for molding the soft spray nozzles can be connected. This allows for easy customization during the injection molding process of the showerhead spray nozzles. For different showerhead spray nozzle products, a single liquid silicone sprue nozzle introduces liquid silicone into the mold cavity via a side-entry method. Only the mold cavity needs to be modified to accommodate different showerhead spray nozzle products. This simplifies the design process, facilitates the standardization and modularization of injection molds, and streamlines mold maintenance, ultimately improving product quality, reducing costs, and increasing efficiency. Furthermore, for the simplified showerhead panel design, the sprue nozzle does not need to be directly applied to the showerhead spray nozzle product, effectively solving the injection molding problem for densely packed spray nozzles.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0036] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0037] In related technologies, the secondary overmolding injection molding method, where the liquid silicone sprue is directly applied to the product surface, places certain requirements on the arrangement of the water outlets in the showerhead's silicone water spray mesh. Because the mold strength around the silicone sprue is relatively weak, an overly dense arrangement of the soft silicone water spray mesh nozzles can easily lead to poor sealing of the mold core, resulting in overflow and blockage of the nozzles. Furthermore, the dense arrangement of the soft silicone water spray mesh nozzles limits the specifications of the liquid silicone sprue, leading to high costs and instability, and in some cases, insufficient space for proper arrangement. Simultaneously, due to varying product sizes, each product requires custom-designed liquid silicone sprues, resulting in significant waste in mold development costs, subsequent maintenance, and mold recycling, hindering the promotion of standardized and modular design.
[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a cross-sectional view of the front structure of a shower panel provided in an embodiment of this application. Figure 2 This is a schematic diagram of the back structure of a shower panel provided in an embodiment of this application. Figure 3 yes Figure 2 The diagram shows a partial cross-sectional view of the shower head panel. Figure 4 This is a schematic diagram of a shower head with an integrated shower panel provided in an embodiment of this application. The back of the shower panel 100 may have a plurality of annular grooves 101 radially distributed along the shower panel 100, and a set of perforated holes 102 corresponding to each annular groove 101. Each annular groove 101 in the shower panel 100 is independently distributed, and adjacent annular grooves 101 in the shower panel 100 are separated by a partition 103. For example, the shower panel 100 may be a structure made of high-temperature resistant hard plastic, such as PBT plastic material.
[0039] The front of the shower panel 100 may have a pouring groove 104 and a plurality of through holes k1 corresponding to and communicating with the pouring groove 104 and a plurality of annular grooves 101. The pouring groove 104 may have a blind end k2 and an open end k3 disposed opposite to each other along the extension direction of the pouring groove 104, and the open end k3 of the pouring groove 104 may be distributed in the edge area of the shower panel 100.
[0040] The inlet groove 104 and multiple through holes k1 in the shower panel 100 can be used to guide the hydraulic silicone of the molded shower head water outlet mesh into multiple annular grooves 101 for curing. It should be noted that the structure of the shower head water outlet mesh and the molding mold will be described in subsequent embodiments.
[0041] In this embodiment, by providing a sprue 104 in the shower panel 100, multiple independent annular grooves 101 areas used for molding the shower spray net can be connected. Thus, for different shower spray net products, during the injection molding process, a liquid silicone sprue nozzle introduces liquid silicone into the mold cavity via a side-guided injection method. Only the mold cavity needs to be modified to accommodate different shower spray net products. This simplifies the design process, facilitates the standardization and modularization of injection molds, and streamlines mold maintenance, thereby improving product quality, reducing costs, and increasing efficiency. Furthermore, for the simplified shower panel structure, the mold sprue nozzle does not need to be directly applied to the shower product, effectively solving the injection molding problem for densely packed shower spray net nozzles.
[0042] In summary, this application provides a shower panel that connects multiple independent annular groove areas used for molding the soft rubber spray net by setting an inlet groove in the shower panel. Thus, during the injection molding process of the shower spray net, for different shower spray net products, a liquid silicone inlet nozzle is used to introduce liquid silicone into the mold cavity via a side-entry method. Only the mold cavity needs to be modified to adapt to different shower spray net products. This simplifies the design process, facilitates the standardization and modularization of injection mold design, and streamlines mold maintenance, thereby improving product quality, reducing costs, and increasing efficiency. Furthermore, the simplified shower panel structure design, with the mold inlet nozzle fixed and not directly applied to the shower spray net product, effectively solves the injection molding problem for densely packed shower spray net nozzles.
[0043] Optional, please refer to Figure 5 , Figure 5 This is a partial structural diagram of a shower head water outlet network integrated with a shower head panel provided in this application embodiment. The edge of the shower head panel 100 has auxiliary pouring bosses 105 distributed on both sides of the opening end k3 of the pouring groove 104. The auxiliary pouring bosses 105 have an upper inclined surface m1, a supporting plane m2, and a lower inclined surface m3 on the side away from the center of the shower head panel 100. The supporting plane m2 can be connected to the upper inclined surface m1 and the lower inclined surface m3 respectively, and the supporting plane m2 can be arranged parallel to the extension direction of the pouring groove 104. The included angle α1 between the upper inclined surface m1 and the supporting plane m2 can be an obtuse angle, and the included angle α2 between the lower inclined surface m3 and the supporting plane m2 can be an acute angle. The upper inclined surface m1 and the lower inclined surface m3 can be located on the upper and lower sides of the supporting plane m2 respectively.
[0044] In this configuration, when the mold cavity surface is pressed onto the shower head panel, the portion of the mold pressing against the supporting plane m2 provides a fulcrum for the supporting lower inclined surface m3, thus providing effective force to the supporting lower inclined surface m3 and preventing overflow of adhesive at the supporting lower inclined surface, ensuring pre-press sealing. The design of the supporting upper inclined surface m1 and the supporting lower inclined surface m3 facilitates a tight fit between the shower head panel 100 and the mold cavity surface under certain pressure after placement, effectively preventing overflow of liquid silicone from both sides of the inlet groove, ensuring a good molding effect for the shower head water outlet screen, and also facilitating the separation of the mold from the shower head water outlet screen after molding.
[0045] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, the orthographic projection of the inlet groove 104 in the shower panel 100 onto the shower panel 100 can be U-shaped.
[0046] Optional, such as Figure 1and Figure 2 As shown, each of the annular grooves 101 in the shower head panel 100 may contain a plurality of perforated holes 102. For example, the plurality of perforated holes 102 corresponding to each annular groove 101 may be distributed along the extension direction of the annular groove 101, for example, the plurality of perforated holes 102 may be equidistantly distributed.
[0047] This application also provides a shower head water outlet mesh, please refer to... Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 6 This is a schematic diagram of the structure of a shower head water outlet net provided in an embodiment of this application. Figure 7 yes Figure 6 The diagram shown is a schematic representation of the back of the showerhead's spray pattern. Figure 8 yes Figure 6 The diagram shows a top view of the showerhead's water spray pattern. Figure 9 yes Figure 8 A cross-sectional view at A-A'. The shower head water outlet mesh 00 may include: a shower head panel 100 and a water outlet mesh soft rubber 200 fastened together, the water outlet mesh soft rubber 200 being a structure formed by curing liquid silicone. Here, the shower head panel 100 can be any of the shower head panels given above. The shower head water outlet mesh can be injection molded using a two-stage overmolding method.
[0048] Please refer to the following in this application: Figure 10 , Figure 10 This is a partial cross-sectional view of a water outlet mesh soft rubber provided in an embodiment of this application. The water outlet mesh soft rubber 200 may have a plurality of water outlet protrusions 201 corresponding one-to-one with the hollow holes 102 in the shower panel 100. Each water outlet protrusion 201 may have a water outlet hole k4, and the end of each water outlet protrusion 201 may extend from the corresponding hollow hole 102.
[0049] This application embodiment also provides a mold 300 for manufacturing the shower head water outlet mesh 00. Please refer to [link / reference]. Figure 11 and Figure 12 , Figure 11 This is a cross-sectional view of a mold provided in an embodiment of this application. Figure 12This is a schematic diagram of the shower head water outlet mesh effect after mold opening and molding. The mold 300 may have a model core 301 adapted to the shape of the shower head panel 100 in the shower head water outlet mesh 00, a runner 302 arranged side-by-side with the sprue groove 104 in the shower head panel 100 and having one end connected to the opening end k3 of the sprue groove 104, a sprue column 303 connected to the other end of the runner 302, and a sprue nozzle 304 connected to the sprue column 303. Here, the shower head water outlet mesh 00 can be the shower head water outlet mesh given above. Here, for different shower head water outlet mesh products, while keeping the liquid silicone sprue nozzle unchanged, the height dimension of the sprue column near the runner side is finely adjusted according to the parting line differences of different products to achieve rapid response, meet the mold opening requirements of different products, and achieve the purpose of standardized and modular design.
[0050] Liquid silicone can be introduced from the side into the sprue 104 in the shower panel 100 through the sprue column 303 and the flow channel 302 via the sprue column 303.
[0051] In this way, compared to the limitation of directly applying multiple liquid silicone nozzles to the shower head spray net product, which is restricted by the product itself, the liquid silicone nozzle of the mold in this application can be set in a fixed state on the outer edge of the mold. That is, for different shower head spray net products, a single liquid silicone nozzle is used to introduce liquid silicone into the mold cavity through lateral glue introduction. Only the mold cavity needs to be changed to adapt to different shower head spray net products. This simplifies the design process, facilitates the standardization and modularization of injection mold design, and the later maintenance of the mold, thereby improving product quality, reducing costs, and increasing efficiency.
[0052] It should be noted that after the "liquid silicone" molded water outlet soft rubber has cured, depending on the product assembly requirements, the auxiliary inlet boss and the soft rubber distribution channel on it can be cut off together, leaving only the molded rubber-coated finished product, without affecting the product assembly requirements.
[0053] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
[0054] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
