Description

Technical Field

[0001] This application relates to the field of manufacturing technology for water ion generating equipment accessories, and in particular to an injection molding device for water ion support. Background Technology

[0002] The water ion holder is a core component of the water ion generator in a hair dryer. It needs to have insulating and support properties, and also needs to embed metal springs to achieve conductive connection. Currently, water ion holders are generally manufactured using injection molding. By embedding metal springs during the injection molding process, the holder molding and spring assembly can be completed in one step, which significantly improves production efficiency compared to the subsequent welding process.

[0003] In the existing water ion stent injection molding process, it is necessary to fix the metal spring in the molding cavity of the mold before injection molding the water ion stent so that the metal spring is embedded in the injection molded water ion stent.

[0004] Regarding the aforementioned technologies, the inventors believe that metal springs simply fixed in the molding cavity are prone to displacement due to the impact of the material flow when the injection molding material is injected into the molding cavity during the injection molding process. This causes a deviation in the preset installation position of the metal spring and the water ion support, reducing the connection stability. Utility Model Content

[0005] The purpose of this application is to provide an injection molding device for water ion support, so as to improve the problem that metal springs that are simply fixed in the molding cavity are easily displaced by the impact of the material flow when the injection molding material is injected into the molding cavity, causing the metal springs to deviate from the preset installation position of the water ion support and reducing the connection stability.

[0006] The water ion support injection molding apparatus provided in this application adopts the following technical solution: A water ion support injection molding device includes a fixed mold and a moving mold that cooperate with each other. The fixed mold is provided with an insert for fixing a metal spring. The fixed mold is provided with a positioning groove adapted to the insert. The insert is provided with a spring placement groove for pre-fixing the metal spring. The fixed mold is provided with a molding cavity adapted to the shape of the pre-injected water ion support between the opposite inserts. The moving mold is provided with a molding protrusion corresponding to the molding cavity.

[0007] By adopting the above technical solution, the insert for fixing the metal spring is integrated into the fixed mold. The insertion can be quickly and accurately installed in the fixed mold by matching the positioning groove, which prevents the metal spring from being misaligned with the water ion support due to the positional deviation of the insert. The spring placement groove pre-fixes the metal spring, which can initially limit the position of the metal spring before injection molding, preventing the metal spring from shifting under the impact of the injection plastic, and ensuring the pre-set assembly relationship between the spring and the water ion support. The shape of the molding cavity and the pre-injected water ion support are matched, and the molding protrusion of the moving mold corresponds to the molding cavity. The two enclose a molding space that is completely matched with the water ion support, ensuring that the shape of the support after injection molding meets the design requirements, reducing subsequent trimming processes, and improving molding accuracy and production efficiency.

[0008] Optionally, the positioning grooves are located at both ends of the molding cavity, and the metal springs between the inserts are arranged along the length of the inner wall of the molding cavity. A molding groove communicating with the molding cavity is opened on the side of the insert near the molding cavity.

[0009] By adopting the above technical solution, the metal springs are arranged along the length of the inner wall of the molding cavity, so that the metal springs are linearly distributed inside the bracket and consistent with the structural direction of the bracket. This ensures that the springs provide support and assistance to the bracket, and prevents the overall structural stability of the bracket from being affected by deviations in the direction of the springs. A molding groove is opened on the side of the insert near the molding cavity and is connected to the molding cavity, so that a smooth injection space is formed between the insert and the molding cavity. This prevents dead corners, material shortages or flash from being generated during injection molding due to steps or gaps between the insert and the molding cavity, and improves the surface smoothness and molding integrity of the water ion bracket.

[0010] Optionally, the inner wall of the spring placement slot is provided with a magnetic adsorption element for adsorbing the metal spring. The magnetic adsorption element is embedded inside the insert and the side wall of the magnetic adsorption element is provided with a slot corresponding to the metal spring. The end of the insert is located on one side of the magnetic adsorption element and has a slot corresponding to the end of the metal spring fixed to the opposite insert.

[0011] By adopting the above technical solution, the magnetic adsorption component on the inner wall of the spring piece placement slot achieves initial fixation of the metal spring piece through magnetic force. The slot on the side wall of the magnetic adsorption component corresponds to the metal spring piece. The slot can limit the lateral displacement of the metal spring piece, prevent the metal spring piece from shifting under the lateral impact of the injection molding, and further improve the fixation stability of the spring piece. The slot at the end of the insert corresponds to the end of the metal spring piece on the opposite insert, which can accurately position the end position of the metal spring piece and ensure that the metal spring pieces on the two opposite inserts are in the same straight line or in a preset position relationship.

[0012] Optionally, the fixed mold has a limiting groove on one side wall of the positioning groove, and the insert has a limiting rod corresponding to the limiting groove.

[0013] By adopting the above technical solution, the limiting groove on one side wall of the fixed mold positioning groove cooperates with the limiting rod inserted in the insert, which can limit the longitudinal and lateral displacement of the insert in the positioning groove, and prevent the insert from floating, sinking or shifting to the side under the impact force of mold closing or the pressure of injection plastic; at the same time, this structure can play a guiding role when the insert is installed, ensuring that the insert is quickly embedded into the preset position of the positioning groove, reducing the adjustment time during manual installation and improving assembly efficiency.

[0014] Optionally, the moving mold is provided with an injection pipe, and a main channel connected to the outlet of the injection pipe is provided between the fixed mold and the moving mold. The main channel is provided with branch channels connected to the interior of each molding cavity.

[0015] By adopting the above technical solution, the injection pipe inside the moving mold provides a stable conveying channel for injection molding raw materials. The main channel between the fixed mold and the moving mold can collect and buffer the raw materials conveyed by the injection pipe. The branch channels enable a single injection system to feed multiple molding cavities simultaneously, which can increase the number of products injected in a single injection and improve production efficiency.

[0016] Optionally, the fixed mold is provided with a positioning groove two corresponding to the forming protrusion on the side facing the moving mold, and the positioning groove two is provided along the width direction of the forming cavity.

[0017] By adopting the above technical solution, the positioning groove 2 on the side of the fixed mold facing the moving mold corresponds to the forming protrusion. During the mold closing process, the forming protrusion can be embedded in the positioning groove 2 first to form a pre-positioning guide, preventing the forming protrusion from being misaligned with the forming cavity due to the alignment deviation when the moving mold and the fixed mold are closed. The positioning groove 2 is set along the width direction of the forming cavity, which can limit the moving mold in the width direction of the forming cavity, ensuring that the moving mold will not shift along the width direction of the forming cavity when the mold is closed, and ensuring that the fitting gap between the forming protrusion and the forming cavity is uniform.

[0018] Optionally, a fixing post is provided on the inner sidewall of the molding cavity. A metal rod is inserted into the fixing post and the metal rod is embedded in the water ion support between adjacent metal springs. A wedge-shaped groove is provided on the outer side of the fixing post along its length direction. The wedge-shaped groove corresponds to the triangular protrusion on the sidewall of the metal spring.

[0019] By adopting the above technical solution, the fixing column in the molding cavity provides a stable mounting carrier for the metal rod, so that the metal rod can be accurately embedded in the water ion support. The wedge-shaped groove on the outside of the fixing column corresponds to the triangular protrusion on the side wall of the metal spring sheet. The two form a concave-convex fit structure, which can restrict the rotation of the metal spring sheet around its own axis or the sliding along the length direction of the molding cavity during the injection molding process.

[0020] Optionally, the side of the forming protrusion facing the forming cavity is provided with a forming column corresponding to the holes at both ends of the water ion support, and the forming protrusion is provided with a fixing rod that abuts against the triangular protrusion of the metal spring sheet.

[0021] By adopting the above technical solution, the molding column facing the molding cavity of the molding protrusion corresponds to the holes at both ends of the water ion support. The holes at both ends of the water ion support can be directly formed during the injection molding process without the need for subsequent drilling, reducing process steps and processing costs. At the same time, it ensures the positional accuracy and coaxiality of the holes, preventing the water ion support from failing to connect with external components due to hole position deviations during subsequent assembly. The fixing rod on the molding protrusion abuts against the triangular protrusion of the metal spring sheet. After mold closing, the fixing rod applies a stable clamping force to the metal spring sheet, further limiting the displacement of the metal spring sheet under the impact of the injection molding material.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The insert for fixing the metal spring is integrated into the fixed mold. The insert can be quickly and accurately installed in the fixed mold by matching the positioning groove, which prevents the metal spring and the water ion support from being misaligned due to the position deviation of the insert. The spring placement groove pre-fixes the metal spring, which can initially limit the position of the metal spring before injection molding, prevent the metal spring from shifting under the impact of the injection plastic, and ensure the pre-set assembly relationship between the spring and the water ion support. 2. The fixing post inside the molding cavity provides a stable mounting carrier for the metal rod, enabling the metal rod to be accurately embedded inside the water ion support. The wedge-shaped groove on the outside of the fixing post corresponds to the triangular protrusion on the side wall of the metal spring sheet. The two form a concave-convex fit structure, which can restrict the rotation of the metal spring sheet around its own axis or the sliding along the length of the molding cavity during the injection molding process. 3. The molding column facing the molding cavity corresponds to the holes at both ends of the water ion support. The holes at both ends of the water ion support can be directly formed during the injection molding process without the need for subsequent drilling, reducing the number of steps and processing costs. At the same time, it ensures the positional accuracy and coaxiality of the holes, preventing the water ion support from failing to connect with external components due to hole position deviations during subsequent assembly.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0026] Water ion support injection molding device, refer to Figure 1 , Figure 2 and Figure 3 The system includes a fixed mold 1 and a moving mold 2, which are connected to the fixed end and drive end of the injection molding machine, respectively. The mold can be driven by the injection molding machine to achieve mold closing and opening actions. The fixed mold 1 has multiple positioning grooves 11 spaced apart inside, each groove 11 containing an insert 3. A molding cavity 12, matching the shape of the pre-injected water ion support 5, is located in the middle of the fixed mold 1, between two opposing sets of inserts 3. The positioning grooves 11 are located at both ends of the subsequent molding cavity 12. The sidewalls of the inserts 3 have spring clip placement grooves 31, and the inner walls of the spring clip placement grooves 31 are embedded with magnetic adsorption components 33, which are permanent magnets. The side wall of insert 3 is provided with a slot 331 that is adapted to the metal spring 4. The metal spring 4 can be embedded in the slot 331 and pre-fixed by the magnetic force of the magnetic adsorption member 33. The end of insert 3, located on one side of the magnetic adsorption member 33, is also provided with a slot 34. The slot 34 corresponds to the end of the metal spring 4 on the other insert 3. The end of the metal spring 4 can be inserted into the slot 34 to achieve end positioning. The fixed mold 1 is provided with a limiting groove 13 that communicates with the positioning groove 11. The side wall of insert 3 is provided with a limiting rod 35 that is adapted to the limiting groove 13. After the limiting rod 35 enters the limiting groove 13, it can limit the displacement of insert 3 in the positioning groove 11.

[0027] Reference Figure 2 and Figure 3A fixing post 121 is installed on the inner side wall of the molding cavity 12. The interior of the fixing post 121 allows the insertion of a metal rod 6. After the metal rod 6 is inserted, it can be pre-embedded in the water ion support 5 during the injection molding process. A wedge-shaped groove 122 is provided on the outer side of the fixing post 121 along its length direction. The wedge-shaped groove 122 is adapted to the triangular protrusion on the side wall of the metal spring sheet 4. The triangular protrusion of the metal spring sheet 4 can be embedded in the wedge-shaped groove 122. A positioning groove 2 14 is provided on the side of the fixed mold 1 facing the moving mold 2 along the width direction of the molding cavity 12. The positioning groove 2 14 corresponds to the molding protrusion 21 of the subsequent moving mold 2.

[0028] Reference Figure 1 and Figure 4 The moving mold 2 has an integrally formed molding protrusion 21 on the side facing the fixed mold 1, which is adapted to the molding cavity 12. The molding protrusion 21 has an integrally formed molding column 24 on the side facing the molding cavity 12, which corresponds to the holes at both ends of the water ion support 5. A fixing rod 25 is also fixedly connected to the molding protrusion 21. The end of the fixing rod 25 can abut against the triangular protrusion of the metal spring sheet 4. An injection pipe 22 is opened inside the moving mold 2. The inlet of the injection pipe 22 is connected to the discharge end of the injection molding machine. After the fixed mold 1 and the moving mold 2 are closed, a main channel 23 is formed between them, which is connected to the outlet of the injection pipe 22. The main channel 23 extends along the length of the fixed mold 1, and the main channel 23 branches towards each molding cavity 12 to form a branch channel 231. The other end of the branch channel 231 is connected to the inside of the molding cavity 12, which can transport the injection molding material into the molding cavity 12.

[0029] Reference Figure 2 and Figure 3 On the side of the insert 3 near the molding cavity 12, there is a molding groove 32 that is connected to the molding cavity 12. The shape of the molding groove 32 is connected to the inner wall contour of the molding cavity 12, so that a smooth injection space is formed between the insert 3 and the molding cavity 12, preventing dead corners from being generated during injection.

[0030] The implementation principle of this application embodiment is as follows: First, insert the metal spring 4 into the spring placement groove 31 of the insert 3. The side wall of the metal spring 4 is embedded in the slot 331 of the magnetic adsorption component 33, and the end of the metal spring 4 is inserted into the slot 34 of the insert 3, thus completing the precise positioning of the metal spring 4. Then, insert the metal rod 6 into the fixing post 121 on the inner side wall of the molding cavity 12 to ensure the stability of the position of the metal rod 6. Insert the insert 3 with the assembled metal spring 4 into the positioning groove 11 of the fixed mold 1, so that the limiting rod 35 on the insert 3 is inserted into the limiting groove 13 on the side wall of the positioning groove 11, thus limiting the displacement of the insert 3 and completing the installation and fixation of the insert 3 in the fixed mold 1. Start the injection molding machine to close the mold, and the injection molding machine injects the molten insulating material. The raw material is transported to the main channel 23 through the injection pipe 22 of the moving mold 2. The raw material in the main channel 23 is then evenly distributed to each molding cavity 12 through the branch channels 231. The raw material fills the molding cavity 12 and at the same time wraps the molding groove 32 part of the insert 3, the metal spring 4 and the metal rod 6 in the fixing post 121. After the raw material in the molding cavity 12 is fully filled, the mold closing pressure is maintained for a period of time to allow the raw material to cool and solidify in the molding cavity 12, forming a water ion support 5 that is consistent with the shape of the molding cavity 12 and integrates the metal spring 4 and the metal rod 6. After the mold is opened, the formed water ion support 5 and the Nantong insert 3 are taken out together. The insert 3 and the water ion support 5 are separated manually. The insert 3 that fixes the metal spring 4 is integrated into the fixed mold 1. The insert 3 can be accurately installed in the fixed mold 1 by matching the positioning groove 11 with the insert 3, so as to prevent the metal spring 4 and the water ion support 5 from being misaligned due to the position deviation of the insert 3. The spring placement groove 31 pre-fixes the metal spring 4, which can initially limit the metal spring 4 before injection molding, prevent the metal spring 4 from shifting under the impact of the injection molding, and ensure the accurate pre-installation position of the spring and the water ion support.
