Description

Technical Field

[0001] This utility model relates to the field of mold making technology for hair dryer inner shells, and in particular to a mold for making hair dryer inner shells. Background Technology

[0002] A typical hair dryer's core components include a motor, fan blades, heating elements, and a complex circuit board. These components are not randomly stacked, but are precisely and securely housed within a structure built by the inner casing.

[0003] The inner shell, much like the human skeletal system, provides anchor points and support for all the "organs." The motor needs to be securely fixed to counteract the vibrations generated by high-speed rotation; the fan blades must be precisely aligned with the motor shaft and work in conjunction with a specific air duct structure to ensure efficient and directional airflow; the heating wire is carefully wound onto high-temperature resistant mica sheets, and the entire heating element is securely enclosed by clips or supports on the inner shell. Therefore, the design of the inner shell directly determines whether all core components can work collaboratively, efficiently, and stably.

[0004] The existing molds for manufacturing the inner shell of hair dryers generally require the use of a motor or hydraulic cylinder to drive the gears for forming the threads, which greatly increases the processing cost. If the motor or hydraulic cylinder is damaged, there will also be repair costs.

[0005] Therefore, in this utility model patent application, the applicant has carefully researched a mold for manufacturing the inner shell of a hair dryer to solve the above problems. Utility Model Content

[0006] This utility model addresses the shortcomings of the existing technology by providing a mold for manufacturing the inner shell of a blower. It allows the installation of the internal thread forming part to be completed after the upper mold is assembled, rather than after the upper and lower molds are closed. This provides greater flexibility, simplifies the structure of the lower mold, and allows only the upper mold to be replaced if damage occurs, thus greatly reducing purchase and maintenance costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mold for manufacturing the inner shell of a hair dryer includes an upper mold and a lower mold. The upper mold includes a panel and an upper template from top to bottom. The lower end face of the upper template is recessed upwards with a first groove, and an upper mold core is installed in the first groove.

[0009] The lower end face of the upper mold core is formed with an upper cavity. The upper end face of the upper mold core is recessed downward to provide a second groove that communicates with the upper cavity. A forming slider for forming the internal thread on the inner wall of the blower inner shell is slidably installed in the second groove. One end of the forming slider near the inner wall of the second groove abuts against the inner wall of the second groove through a reset elastic element.

[0010] The end face of the forming slider away from the inner wall of the second groove has a first inclined surface. The lower end face of the end of the forming slider away from the inner wall of the second groove extends downward to form an extension. The extension extends into the upper cavity. The outer side of the extension forms an internal thread forming part for forming internal threads.

[0011] The lower end face of the panel is connected to a push block for driving the forming slider to approach or move away from the inner wall of the second groove. The push block is provided with a second inclined surface that adapts to the first inclined surface. The upper template is provided with a first through hole for the push block to pass through, and the first through hole communicates with the second groove.

[0012] The panel is installed and connected to the upper template downwards. The push block passes through the first through hole and fits into the second groove. The push block and the forming slider are connected to form a beveled fit. The push block pushes the forming slider to slide outwards horizontally. The reset elastic element is compressed and deformed. The gap between the internal thread forming part and the upper cavity is always maintained.

[0013] After the panel is separated from the upper template, the forming slider is reset inward under the reset force of the reset elastic element to separate from the internal thread of the finished product.

[0014] As a preferred embodiment, the push-down block is a detachable connection panel.

[0015] As a preferred embodiment, the lower end face of the panel is recessed upward to form a first mounting groove, the push block is installed in the first mounting groove and extends out of the panel, the upper end face of the panel is provided with a first screw hole communicating with the first mounting groove, a first screw is provided in the first screw hole, the upper end face of the push block is provided with a second screw hole, and the panel is connected to the push block by the first screw passing through the first screw hole and the second screw hole in sequence.

[0016] As a preferred embodiment, a limiting block is installed in the second groove, and the limiting block has a limiting groove that connects to the upper cavity. The forming slider is slidably installed in the limiting groove, and the two ends of the reset elastic member are respectively connected to the inner sidewall of the forming slider and the limiting groove.

[0017] As a preferred embodiment, the end face of the forming slider near the inner sidewall of the second groove is recessed into a receiving groove, and the end of the reset elastic member near the forming slider abuts against the inner end wall of the receiving groove.

[0018] After the panel is connected to the upper template, the reset elastic element is compressed and deformed and installed entirely in the receiving groove, and the forming slider abuts against the inner wall of the limiting groove.

[0019] As a preferred embodiment, four limiting grooves are provided and arranged in a cross shape. Correspondingly, four forming sliders are also provided. Each limiting groove is equipped with a forming slider, and the intersection of the four limiting grooves allows the push block to pass through.

[0020] As a preferred embodiment, the upper end face of the limiting block is connected to a cover plate for preventing the forming slider from moving upward, and the cover plate has a second through hole for the push block to pass through.

[0021] As a preferred embodiment, the lower mold includes a lower template and a lower mold core disposed on the lower template. The upper end face of the lower mold core forms a lower cavity, and a forming protrusion is disposed inside the lower cavity.

[0022] The lower mold and the upper mold are connected, and the forming protrusion extends into the upper cavity and abuts against the extension. The upper cavity, the lower cavity, the forming protrusion, the extension, and its internal thread forming part together form a forming cavity.

[0023] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly uses the second inclined surface of the push block connected to the panel and the inclined surface of the forming slider located in the second groove of the upper mold core to cooperate, so that the installation of the internal thread forming part can be completed after the upper mold is assembled, instead of only after the upper and lower molds are closed. It has better flexibility, simplifies the structure of the lower mold, and if damage occurs, only the upper mold needs to be replaced, without replacing the entire mold, which greatly reduces the purchase cost and maintenance cost.

[0024] Secondly, by connecting four forming sliders simultaneously with one push block, segmented internal threads can be achieved on the inner wall of the blower inner shell, greatly simplifying the complexity and structure of the overall mold and reducing processing costs.

[0025] Secondly, the detachable design of the push block and forming slider allows for the replacement of different push blocks and forming sliders to adapt to different slope requirements and different thread size requirements, further improving flexibility.

[0058] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0059] like Figure 1 and Figure 11 As shown, a mold for making the inner shell of a hair dryer includes an upper mold 10 and a lower mold 20.

[0060] The upper mold 10 includes a panel 11 and an upper template 12 from top to bottom.

[0061] The lower end face of the upper template 12 is recessed upwards with a first groove 121, and the upper mold core 13 is installed in the first groove 121.

[0062] The lower end face of the upper mold core 13 forms an upper cavity 131, and the upper end face of the upper mold core 13 is recessed downward to provide a second groove 132 that communicates with the upper cavity 131. A forming slider 14 for forming the internal thread on the inner wall of the blower inner shell is slidably installed in the second groove 132.

[0063] The second groove 132 is equipped with a limiting block 15, and the limiting block 15 has a limiting groove 151 that connects to the upper cavity 131. The forming slider 14 is slidably installed in the limiting groove 151.

[0064] In this embodiment, four limiting grooves 151 are provided and arranged in a cross shape. Correspondingly, four forming sliders 14 are also provided. Each limiting groove 151 contains one forming slider 14, and the intersection of the four limiting grooves 151 allows the push block 18 to pass through. Through the cooperation of the four forming sliders 14, a segmented internal thread can be achieved on the inner wall of the product. The segmented internal thread can be simplified by using the inward sliding position of this embodiment to reduce the complexity of the overall mold. Although the thread is simplified, the function of the thread remains the same.

[0065] The upper end face of the limiting block 15 is connected to a cover plate 16 for preventing the forming slider 14 from moving upward. The cover plate 16 has a second through hole 161 for the push block 18 to pass through.

[0066] One end of the forming slider 14 near the inner wall of the second groove 132 abuts against the inner wall of the second groove 132 via a reset elastic member 17. Preferably, the two ends of the reset elastic member 17 are respectively connected to the inner walls of the forming slider 14 and the limiting groove 151. Further, one end face of the forming slider 14 near the inner wall of the second groove 132 is recessed into a receiving groove 141, and one end of the reset elastic member 17 near the forming slider 14 abuts against the inner end wall of the receiving groove 141.

[0067] After the panel 11 is connected to the upper template 12, the reset elastic element 17 is compressed and deformed and is installed in the receiving groove 141, and the forming slider 14 abuts against the inner wall of the limiting groove 151.

[0068] The end face of the molding slider 14 away from the inner wall of the second groove 132 has a first inclined surface 142. The lower end face of the end of the molding slider 14 away from the inner wall of the second groove 132 extends downward to form an extension 143. The extension 143 extends into the upper cavity 131. The outer side of the extension 143 forms an internal thread forming part 144 for forming internal threads.

[0069] The lower end face of the panel 11 is connected to a push block 18 for driving the forming slider 14 to move closer to or away from the inner wall of the second groove 132. In this embodiment, the push block 18 is detachably connected to the panel 11.

[0070] The lower end face of the panel 11 is recessed upwards with a first mounting groove 111. The push block 18 is installed in the first mounting groove 111 and extends out of the panel 11. The upper end face of the panel 11 is provided with a first screw hole 112 that communicates with the first mounting groove 111. A screw 113 is provided in the first screw hole 112. The upper end face of the push block 18 is provided with a second screw hole 181. The panel 11 is connected to the push block 18 by the screw 113 passing through the first screw hole 112 and the second screw hole 181 in sequence.

[0071] The push block 18 is provided with a second inclined surface 182 adapted to accommodate the first inclined surface 142. The upper template 12 has a first through hole 122 for the push block 18 to pass through, and the first through hole 122 connects to the second groove 132. In this embodiment, four second inclined surfaces 182 are provided and are respectively located on the lower part of the front, rear, left, and right sides of the push block 18, which enables one push block 18 to simultaneously cooperate and connect with four forming sliders 14.

[0072] The lower mold 20 includes a lower template 21 and a lower mold core 22 disposed on the lower template 21. The upper end surface of the lower mold core 22 forms a lower cavity 221, and a forming protrusion 23 is disposed in the lower cavity 221.

[0073] The lower mold 20 and the upper mold 10 are connected. The forming protrusion 23 extends into the upper cavity 131 and abuts against the extension 143. The upper cavity 131, the lower cavity 221, the forming protrusion 23, the extension 143, and the internal thread forming part 144 together form a forming cavity.

[0074] The panel 11 is installed and connected to the upper template 12 downwards. The push block 18 passes through the first through hole 122 and is adapted to the second groove 132. The push block 18 and the forming slider 14 are connected to form a beveled fit. The push block 18 pushes the forming slider 14 to slide outwards horizontally. The reset elastic element 14 is compressed and deformed. The gap between the internal thread forming part 144 and the upper cavity 131 is always maintained.

[0075] After the panel 11 is separated from the upper template 12, the forming slider 14 is reset inward under the reset force of the reset elastic element 17 to separate from the internal thread of the finished product.

[0076] The key design feature of this utility model is that it mainly uses the second inclined surface of the push block connected to the panel and the inclined surface of the forming slider located in the second groove of the upper mold core to cooperate, so that the installation of the internal thread forming part can be completed after the upper mold is assembled, instead of only after the upper and lower molds are closed. This provides better flexibility, simplifies the structure of the lower mold, and if damage occurs, only the upper mold needs to be replaced, without having to replace the entire mold, which greatly reduces purchase and maintenance costs.

[0077] Secondly, by connecting four forming sliders simultaneously with one push block, segmented internal threads can be achieved on the inner wall of the blower inner shell, greatly simplifying the complexity and structure of the overall mold and reducing processing costs.

[0078] Secondly, the detachable design of the push block and forming slider allows for the replacement of different push blocks and forming sliders to adapt to different slope requirements and different thread size requirements, further improving flexibility.

[0079] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
