Description

Technical Field

[0001] The utility model relates to the technical field of hot melt injection molding production, in particular to a shell. Background Art

[0002] In the manufacture of some electronic devices, there is an item for manufacturing the shell of the electronic device. In the manufacturing process of the shell, a mold is usually used to manufacture the shell. On the shell of the electronic device, it is usually necessary to set a button, and the set button needs to be fixed on the shell to prevent the button from falling off. However, the structure for fixing the button on the shell is usually set inside the shell. In the manufacturing of the prior art, a connecting column is usually set inside the shell. After the button assembly is set on the connecting column, the button is fixed to the shell by forming a blocking block through hot melting or a nut. The reason is that a mold cannot be set in the gap between the blocking block and the shell, so the blocking block cannot be formed directly, and a hot melting step or an assembly step needs to be added to form the blocking block. This method is not only complicated in process, but also the button assembly cannot be replaced after manufacturing is completed. Therefore, there is a need for a shell that is easier to manufacture, so that the manufacture of the shell is simpler. Utility Model Content

[0026] Mold design is a crucial component of the manufacturing industry. It involves designing and manufacturing molds suitable for production based on the product's shape, size, and process requirements. Molds largely determine product quality, profitability, and the ability to develop new products, earning them the honorary title of "the mother of industry." From airplanes and automobiles to teacups and nails, nearly all industrial products rely on molds for their formation. The high precision, consistency, and productivity of mold-made parts are unmatched by any other processing method. Mold design must be tailored to the product's shape. However, some products, due to their numerous protrusions, cannot be demolded, so they are manufactured in one go.

[0027] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4The housing in the first embodiment of the present invention includes: a housing 1, a fixing member 2 and a button assembly 3. The housing 1 includes a bottom plate 11 and a side plate 12. The side plate 12 is arranged on the bottom plate 11 and forms a receiving groove 14 for receiving components; the fixing member 2 is fixedly arranged on the inner side 13 of the side plate 12, and the inner side 13 faces the inside of the receiving groove 14. The fixing member 2 includes a blocking block 21 and a connecting rod 22. The first end of the connecting rod 22 is fixedly arranged on the side plate 12, and the second end of the connecting rod 22 is fixedly connected to the blocking block 21. The fixing member 2 includes an upper surface 23 and a lower surface 24, which are surrounded by a stopper 21 and a connecting rod 22. The angle between the normal direction at any position on the upper surface 23 and the first direction is no greater than 90°. The normal direction of the side of the base plate 11 facing the fixing member 2 is the first direction. The distance between the lower surface 24 and the base plate 11 increases sequentially along a second direction, which is the direction from the end of the fixing member 2 closest to the inner surface 13 to the end farther from the inner surface 13. The stopper 21 protrudes relative to the connecting rod 22 on the side facing the upper surface 23. To improve processing efficiency and reduce processing steps, the fixing member 2 and the housing 1 are formed in a single process. In the prior art, the stopper 21 is required on the fixing member 2 to block the key assembly 3 on the connecting rod 22 and prevent it from falling off. This causes the stopper 21 to protrude relative to the connecting rod 22. However, the existing stopper 21 protrudes in multiple directions relative to the connecting rod 22. In particular, the blocking block 21 protrudes from the side of the connecting rod 22 closest to the base plate 11. This prevents the mold from being demolded after the housing 1 and blocking block 21 are formed, effectively trapping the mold in the gap between the fixing member 2 and the housing 1. Therefore, in the prior art, when designing the mold, only the connecting rod 22 is formed on the housing 1, so that the blocking block 21 does not obstruct the mold from being demolded. After demolding, the key assembly 3 is mounted on the connecting rod 22, and then, through methods such as heat fusion, the blocking block 21 is formed on the end of the connecting rod 22 away from the side plate 12. This increases the number of manufacturing steps and reduces manufacturing efficiency. Therefore, in this embodiment, the fixing member 2 is configured as a structure formed by an upper portion 23 and a lower portion 24, wherein the upper portion 23 is formed by one mold and the lower portion 24 is formed by another mold. The upper portion 23 is configured so that the normal angle between any point and the first direction is no greater than 90°, thereby enabling the mold forming the upper portion 23 to be demolded along the first direction. The mold is not blocked in the first direction, so the mold facing upward 23 can be demolded smoothly. The distance between the mold facing downward 24 and the bottom plate 11 increases gradually along the second direction, so that the mold facing downward 24 can be demolded in the second direction, which is away from the side plate 12 and will not be blocked by the housing or the fixing member 2 during demolding.

[0028] The key assembly 3 includes a resilient mounting ring 33 that fits over the connecting rod 22. The stopper 21 is used to hold the mounting ring 33 in place on the connecting rod 22. During installation, the resilient mounting ring 33 is stretched to allow it to pass through the stopper 21 and fit over the connecting rod 22. After fitting over the connecting rod 22, the mounting ring 33 contracts and is held against the connecting rod 22 by the stopper 21, trapping it between the stopper 21 and the side panel 12.

[0029] The injection molding process is a complex and precise process, which involves multiple stages such as raw material preparation, injection molding machine setting, melting plastic, injection, pressure holding, cooling, demoulding, etc. The following are the detailed steps of the injection molding process:

[0030] 1. Preliminary preparation and material selection: Select suitable plastic raw materials according to product requirements, such as thermoplastics (such as PP, PE, ABS) or thermosetting plastics. Material drying: Many plastic materials need to be dried before processing to remove moisture to prevent bubbles, surface defects or degradation of material properties during the injection molding process. Equipment debugging: Set various parameters of the injection molding machine, including injection pressure, injection speed, mold temperature, cooling system, etc. Mold preparation: Mold inspection: Check the integrity, wear and damage of the mold to ensure that the mold can be used normally. Mold installation: Install the mold on the mold base of the injection molding machine, and adjust and fix it to ensure the stability and precision of the mold. Mold preheating: For molds with special requirements, preheating is required to reach the required temperature.

[0031] Second, the injection molding process: Feeding: Plastic pellets or powder are added to the injection molding machine's hopper. Melting: The injection molding machine's heating device and screw feeding system heat the plastic to a molten state, turning it into a flowing molten plastic. During this process, the injection molding machine precisely controls the temperature of the molten plastic to meet product requirements. Injection Process: Mold Closing: The injection molding machine uses a hydraulic system to close the mold, ensuring mold tightness and stability. Plastic Injection: The injection molding machine uses the screw to rotate, injecting the molten plastic into the mold cavity at a specific pressure and speed. Injection pressure and speed should be adjusted according to the mold design and product requirements. Filling: During the injection process, the molten plastic fills the mold cavity, ensuring that the mold interior is completely filled to achieve the complete product shape. Holding Pressure Phase: After the plastic fills the mold cavity, a certain injection pressure is maintained to compensate for shrinkage during cooling and ensure dimensional stability of the product. This phase helps to increase the density and mechanical strength of the plastic part.

[0032] 3. Post-processing cooling: Maintain the mold temperature and allow the plastic to cool in the mold and solidify into the final product shape. The cooling time depends on the type of material, the design of the mold and the thickness of the product. Mold opening and demoulding: After cooling is completed, the injection molding machine will open the mold. The product is removed from the mold by the robot or other auxiliary equipment of the injection molding machine. Trimming: Remove excess parts on the product, such as the flash of the injection port, the gate, etc. Inspection: Perform quality inspection on the product, including size, appearance, function, etc., to ensure that the product meets the specification requirements

[0033] According to some embodiments of the present invention, the connecting rod 22 is cylindrical, with the central axis of the cylinder coinciding with the second direction. The cylinder has a splitting plane, which is parallel to the side of the base plate 11 facing the fixing member 2. The central axis of the cylinder is located within the splitting plane, with the downward-facing portion 24 located on the side of the splitting plane closer to the base plate 11, and the upward-facing portion 23 located on the side of the splitting plane farther from the base plate 11. The surface of the fixing member 2 that coincides with the splitting plane is referred to as the upward-facing portion 23 if it faces upward, and as the downward-facing portion 24 if it faces downward. It should be noted that the splitting plane, like the central axis, is a virtual entity.

[0034] According to some embodiments of the present invention, the second direction is the normal of the inner side surface 13, and the second direction is perpendicular to the first direction. When the second direction is perpendicular to the first direction, the setting of the fixing member 2 saves more space inside the shell 1, and also makes the self-built installation of the button more convenient and accurate.

[0035] According to some embodiments of the present invention, the downwardly facing portion 24 is a flat surface. Setting the downwardly facing portion 24 as a flat surface facilitates demolding. Setting the downwardly facing portion 24 as a flat surface also prevents the button assembly 3 from being blocked by the downwardly facing portion 24 when being installed on the fixing member 2, making installation of the button assembly 3 quicker and smoother. Furthermore, the downwardly facing portion 24 is parallel to the side of the base plate 11 facing the fixing member 2. Specifically, the connecting rod 22 can be configured as half of a cylinder, i.e., the bottom surface of the cylinder is semicircular, with the rectangular flat surface formed therein forming part of the downwardly facing portion 24, and the curved surface forming part of the upwardly facing portion 23. The blocking block 21 can also be configured as half of a cylinder, i.e., the bottom surface of the cylinder is semicircular, with the rectangular flat surface formed therein forming part of the downwardly facing portion 24, and the curved surface forming part of the upwardly facing portion 23. The radius of the semicircular bottom surface of the blocking block 21 is greater than the radius of the semicircular bottom surface of the connecting rod 22. The rectangular flat surface formed on the blocking block 21 and the rectangular flat surface formed on the connecting rod 22 are coplanar and parallel to the side of the base plate 11 facing the fixing member 2.

[0036] According to some embodiments of the present invention, the upper surface 23 includes an inclined region 25 located at the end of the stopper 21 away from the connecting rod 22, with the distance between the inclined region 25 and the lower surface gradually decreasing along the second direction. When the key assembly 3 is mounted on the fixed member 2, the inclined region 25 guides the mounting ring 33 through the stopper more easily. Specifically, the stopper 21 is configured in the shape of a semi-conical cone, wherein the semi-circular bottom surface of the end of the stopper 21 near the connecting rod 22 has a larger radius, while the semi-circular bottom surface of the end of the stopper 21 away from the connecting rod 22 has a smaller radius. The mounting ring 33 can be positioned over the smaller end of the stopper 21 without external force. When the mounting ring 33 is driven to move in a direction opposite to the second direction, the mounting ring 33 is elastically deformed under the force. Under the pressure of the inclined region 25, the mounting ring 33 stretches and passes through the end of the stopper 21 near the connecting rod 22, thereby being trapped between the stopper 21 and the side plate 12.

[0037] According to some embodiments of the present invention, the upper surface 23 includes a vertical region, and the inclined region 25 is located at the end of the stop block 21 near the connecting rod 22. The normal direction of the vertical region is perpendicular to the first direction. The vertical region is the surface of the stop block 21 that blocks the movement of the mounting ring 33 in the second direction. The presence of the vertical region further secures the mounting ring 33 between the stop block 21 and the side plate 12.

[0038] According to some embodiments of the present invention, the adjacent edges of the upper surface 23 and the lower surface 24 are located in the same plane and are parallel to the surface of the base plate 11 facing the fixing member 2. The adjacent edges of the upper surface 23 and the lower surface 24 are arranged to be more flush, which makes the mold design simpler and more convenient, reducing the manufacturing difficulty and improving the quality of the manufactured product.

[0039] According to some embodiments of the present invention, two fixing members 2 are provided on the side panel 12, and both fixing members 2 are used to connect with the key assembly 3. The key assembly 3 can be fixed more firmly and stably by the two fixing members 2.

[0040] According to some embodiments of the present invention, the distances between the two fixing members 2 and the bottom plate 11 are equal, thereby preventing the key assembly 3 from tilting after being mounted on the housing 1 .

[0041] According to some embodiments of the present invention, the key assembly 3 includes a key body 31, a connecting strip 32, and a mounting ring 33. The key body 31 is disposed on the connecting strip 32. The connecting strip 32 is provided with mounting rings 33 at both ends. The mounting rings 33 correspond one-to-one with the fixing member 2. The side panel 12 is provided with a through hole 4. The key body 31 is disposed within the through hole 4. The through hole 4 corresponds one-to-one with the key body 31. The key body 31 can pass through the through hole 4 and extend out of the other end of the pupil, so that the key can be better triggered from outside the housing 1.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
