[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and should not be understood as limiting the embodiments of the present application.

[0041] In the description of the present application, it should be understood that the terms "thickness", "upper", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. In an example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0043] In the embodiments of the present application, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0044] Please combine Figure 1 During the injection molding process, it is inevitable that the gate corresponding to the injection port of the mold will remain on the product. In the case of a transparent area on the product, the user may observe the gate of the product through the transparent area, thus affecting the aesthetics of the product. For example, the current lampshade can be composed of a transparent part and an opaque part. The exterior surface is colorless and transparent, and the back is surrounded by black opaque plastic. Under normal circumstances, since the exterior surface is transparent, the gate remaining on the exterior surface can be seen regardless of how the injection molding is performed. For this type of product, the existing technology basically directly injects the glue into the product on the front of the transparent part, and the product appearance has obvious gate defects.

[0045] In order to solve the above technical problems, the present application provides a mold 100 and a lampshade 200.

[0046] See also Figure 2The mold 100 provided in the embodiment of the present application includes a front mold assembly 10 and a back mold assembly 20, the front mold assembly 10 includes a first front mold core 11 and a second front mold core 12, the back mold assembly 20 includes a back mold core 21 and a fixing assembly 22, the fixing assembly 22 is movably arranged on the back mold core 21, the back mold core 21 is used to sequentially combine with the first front mold core 11 and the second front mold core 12 to sequentially generate a first component 210 corresponding to the first front mold core 11 and a second component 220 corresponding to the second front mold core 12, the fixing assembly 22 corresponds to the first component 210, and is used to fix the first component 210 to the back mold core 21, or release the first component 210; the second component 220 is an opaque component, the injection port 211 corresponding to the first component 210 is located in the injection range corresponding to the second component 220, and the injection port 221 corresponding to the second component 220 is located in the opaque area corresponding to the second component 220

[0047] Specifically, mold 100 is a tool used in industrial production to produce various parts. It uses a press to form metal or non-metal materials into the desired shape. Mold 100 includes a front mold assembly 10 and a rear mold assembly 20. The front mold assembly 10 includes a front mold core, and the rear mold assembly 20 includes a rear mold core 21. The front mold core is typically installed at the top of mold 100 and is used to press the material in mold 100 downward. The rear mold core 21 is installed at the bottom of mold 100 to support the mold 100 and secure the material in place during pressing.

[0048] The front mold assembly 10 and the rear mold assembly 20 can be connected to different parts of the injection molding machine respectively, so that the injection molding machine can control the combination and separation of the front mold core and the rear mold core 21. Grooves are provided in the front mold core and the rear mold core 21, so that when the front mold core and the rear mold core 21 are combined, a cavity is formed between the two. An injection port is provided on the front mold core, and the hot nozzle of the injection molding machine is connected to the injection port, and the injection port is connected to the cavity formed by the front mold core and the rear mold core 21. Therefore, after the front mold core and the rear mold core 21 are combined, the hot nozzle can input the injection molding material into the cavity through the injection port so that the injection molding material fills the entire cavity. After the injection molding material cools, a component with the same shape as the cavity can be formed.

[0049] The rear mold core 21 can move relative to the first front mold core 11 and the second front mold core 12, so that when the front mold assembly 10 and the rear mold assembly 20 are closed, the rear mold core 21 can selectively combine with the first front mold core 11 and the second front mold core 12. The structures of the first front mold core 11 and the second front mold core 12 are different, so that the first cavity formed after the first front mold core 11 and the rear mold core 21 are combined has a different shape from the second cavity formed after the second front mold core 12 and the rear mold core 21 are formed, thereby facilitating the use of the first cavity and the second cavity to generate two different components. Injection ports can be set on the first front mold core 11 and the second front mold core 12, and the injection port 211 of the first front mold core 11 is connected to the first cavity, and the injection port 221 of the first front mold core 11 is connected to the second cavity. The mold 100 includes a first hot nozzle 40 and a second hot nozzle 50, and the output port of the injection molding machine can be connected to the first hot nozzle 40 and the second hot nozzle 50 respectively. The first hot nozzle 40 corresponds to the injection port 211 of the first component 210 , and is used to output injection molding material to generate the first component 210 . The second hot nozzle 50 corresponds to the injection port 221 of the second component 220 , and is used to output injection molding material to generate the second component 220 .

[0050] The rear mold core 21 is combined with the first front mold core 11 and the second front mold core 12 in sequence. Figure 3 , Figure 3 is an injection molding scene diagram of the first component 210, Figure 3 The second component 220 has not yet been generated. When it is necessary to generate the first component 210, the injection molding machine can be used to control the front mold assembly 10 and the rear mold assembly 20 to close the mold, and the rear mold core 21 and the first front mold core 11 are combined. At this time, a first cavity is formed between the rear mold core 21 and the first front mold core 11. The first hot nozzle 40 can be extended into the injection port 211 corresponding to the first component 210 (that is, the injection port 211 of the first front mold core 11), and then plastic is injected into the first cavity through the injection port 211 corresponding to the first component 210 to form the first component 210.

[0051] The fixing assembly 22 corresponds to the first cavity and is movably mounted on the rear mold core 21, so that the fixing assembly 22 can be used to fix the first component 210 to the rear mold core 21 (for example, Figure 5 ), the fixed relationship between the first component 210 and the rear mold core 21 can also be released (for example Figure 6 ), that is, loosen the first component 210. Therefore, after the first component 210 is formed, the fixing assembly 22 can move toward the first component 210 to fix the first component 210 to the rear mold core 21, so as to facilitate the first component 210 to be driven into the second cavity.

[0052] Please combine Figure 4 , Figure 4 is an injection molding scene diagram of the second component 220, Figure 3The first component 210 has been generated. After the first component 210 is formed, the injection molding machine can control the front mold assembly 10 and the rear mold assembly 20 to separate the first front mold core 11 and the rear mold core 21, and then the rear mold core 21 can move toward the second front mold core 12, so that the rear mold core 21 is connected to the second front mold core 12, and form a second cavity. It can be understood that the first component 210 is also driven into the second cavity. The second hot nozzle 50 can extend into the injection port 221 corresponding to the second component 220 (that is, the injection port 221 of the second front mold core 12), and then inject plastic into the second cavity through the injection port 221 corresponding to the second component 220 to form the second component 220. It can be understood that the second component 220 is injection molded on the basis of the first component 210, so the second component 220 is connected to the first component 210, thereby generating the target component (such as Figure 1 As shown). The second component 220 is an opaque component, wherein all areas of the second component 220 may be opaque, or part of the second component 220 may be transparent. It is understood that the opaque areas are non-appearance areas, and the transparent areas are appearance areas. This ensures that it is difficult for a user to see objects behind the opaque areas of the second component 220 through the opaque areas of the second component 220. The first component 210 may be a transparent component or an opaque component, without limitation.

[0053] During the injection molding of the second component 220, if the fixing assembly 22 affects the injection molding of the second component 220, the fixing assembly 22 can be moved in a direction away from the first cavity and the second cavity after the second front mold core 12 and the rear mold core 21 are combined and before the injection molding begins, so that the fixing assembly 22 is away from the first cavity and the second cavity, ensuring that the second component 220 can be smoothly injected and facilitating the demolding of the target component. If the fixing assembly 22 does not affect the injection molding of the second component 220, the fixing assembly 22 can be moved in a direction away from the target component after the injection molding of the second component 220 is completed to facilitate the demolding of the target component.

[0054] It is understood that after each component is injection molded, in addition to the area corresponding to the corresponding cavity, a gate corresponding to the injection port will remain on the component. Figure 3 and Figure 4The injection port 211 corresponding to the first component 210 is located within the injection range corresponding to the second component 220, so that the injection port 211 corresponding to the first component 210 is actually located within the range of the second cavity. The injection material injected by the injection molding machine can continuously impact the injection port 211 corresponding to the first component 210, so that the impact force of the injection material corresponding to the second component 220 flowing can be used to eliminate and dilute the residue of the injection port 211 corresponding to the first component 210. The injection port 221 corresponding to the second component 220 is located in the opaque area corresponding to the second component 220. It can be understood that the injection port 221 corresponding to the second component 220 is located on the non-exterior surface, so that the gate of the second component 220 cannot be viewed by the user. Therefore, the injection port 221 corresponding to the second component 220 can be manually trimmed later.

[0055] In this way, the gate of the first part 210 will be diluted or even flattened when the second part 220 is injection molded, and the gate of the second part 220 can be blocked by the opaque area corresponding to the second part 220, so that the user can view the target part from multiple angles without seeing the gate of the first part 210 or the gate of the second part 220, thereby improving the aesthetics of the target part.

[0056] In the mold 100 according to the embodiment of the present application, the rear mold core 21 is sequentially combined with the first front mold core 11 and the second front mold core 12 to sequentially produce the first component 210 and the second component 220. The injection port 211 corresponding to the first component 210 is located within the injection range corresponding to the second component 220, and the injection port 221 corresponding to the second component 220 is located within the opaque area of ​​the second component 220. In this way, when the second component 220 is injected, the injection material corresponding to the second component 220 can dilute or even flatten the gate of the first component 210. The gate of the second component 220 is located within the opaque area of ​​the second component 220, making it impossible for a user to observe the gate of the second component 220 from the outside of the second component 220. This ensures that the user will not see the gate of the first component 210 or the gate of the second component 220 when viewing the first component 210 and the second component 220 from multiple angles, thereby improving the aesthetics of the first component 210 and the second component 220.

[0057] See also Figure 2In some embodiments, the first front mold core 11 and the second front mold core 12 are arranged around the central axis X1 of the mold 100. For example, the angle between the first front mold core 11 and the second front mold core 12 can be 30°, 60°, 90°, or 180°, and the distance between the central axis of the first front mold core 11 and the central axis X1 of the mold 100 is equal to the distance between the central axis of the second front mold core 12 and the central axis X1 of the mold 100. The back mold core 21 is symmetrically arranged with the first front mold core 11 or the second front mold core 12 along a direction perpendicular to the central axis X1 of the mold 100, so that the back mold core 21 can be combined with the first front mold core 11 and the second front mold core 12.

[0058] The front mold assembly 10 and the rear mold assembly 20 can rotate relative to each other, for example, by rotating the front mold assembly 10 or the rear mold assembly 20 using an injection molding machine, or by rotating both the front mold assembly 10 and the rear mold assembly 20 simultaneously. This allows the rear mold core 21 and the first front mold core 11 to rotate relative to each other, and the rear mold core 21 and the second front mold core 12 to rotate relative to each other. For example, the rear mold core 21 can rotate about the central axis X1 of the mold 100, or the first and second front mold cores 11 and 12 can rotate about the central axis X1 of the mold 100. This allows the rear mold core 21 to selectively engage with the first or second front mold core 11, 12, thereby allowing the mold 100 to sequentially produce the first component 210 and the second component 220. The rotation angle between the rear mold core 21 and the front mold core is determined by the angle between the first and second front mold cores 11 and 12. For example, if the angle between the first and second front mold cores 11 and 12 is 180°, the rotation angle between the rear mold core 21 and the front mold core is also 180°.

[0059] In another embodiment, the mold 100 may also be provided with a slide rail, and the rear mold assembly 20 may be movably provided on the slide rail, or the front mold assembly 10 may be movably provided on the slide rail, so that the rear mold core 21 and the first front mold core 11 can move relative to each other, and the rear mold core 21 and the second front mold core 12 can also move relative to each other, ensuring that the rear mold core 21 can be selectively combined with the first front mold core 11 or the second front mold core 12.

[0060] In this way, the first front mold core 11 and the rear mold core 21 can move relative to each other, and the second front mold core 12 and the rear mold core 21 can also move relative to each other, ensuring that the rear mold core 21 can be selectively combined with the first front mold core 11 or the second front mold core 12, thereby ensuring that the mold 100 can generate the first component 210 in sequence, and drive the first component 210 into the second cavity, and then generate the second component 220 on the first component 210, so that the second component 220 can flatten or dilute the residual gate of the first component 210 during injection molding.

[0061] See also Figure 2In some embodiments, the first front mold core 11 includes multiple, and the rear mold core 21 is sequentially combined with the multiple first front mold cores 11 to sequentially generate multiple first parts 210. The injection port 211 corresponding to the current first part 210 is located within the injection range corresponding to the next generated first part 210. The current first part 210 is any first part 210 among the multiple first parts 210 generated, except for the finally generated first part 210. The injection port 211 corresponding to the finally generated first part 210 is located within the injection range corresponding to the second part 220.

[0062] Specifically, there can be multiple first front mold cores 11, and each first component 210 generated can be a transparent component or an opaque component, which is not limited here. The rear mold core 21 can be combined with multiple first front mold cores 11 in sequence to generate multiple first components 210. At the same time, the injection port 211 corresponding to the current first component 210 is located within the injection molding range corresponding to the next generated first component 210, so that the gate of the current first component 210 will be diluted or flattened by the injection molding material of the next generated first component 210 when the next generated first component 210 is injected, ensuring that the gate of the current first component 210 will not be observed. Among them, the current first component 210 is any first component 210 among the multiple generated first components 210, except the final generated first component 210, and the injection port 211 corresponding to the final generated first component 210 is located within the injection molding range corresponding to the second component 220. The injection port 211 corresponding to the final first component 210 is located within the accommodation range corresponding to the second component 220 , so that the gate of the final first component 210 can be flattened or diluted by the injection material corresponding to the second component 220 .

[0063] In this way, except for the first component 210 that is finally generated, the gates of all first components 210 will be flattened or diluted by the injection molding material corresponding to the next first component 210 when the next first component 210 is generated. The gates of the first component 210 that is finally generated will be flattened or diluted by the injection molding material corresponding to the second component 220 when the second component 220 is generated, so that the gates of all first components 210 will be diluted or even flattened, thereby reducing the possibility of users observing the gates of the first components 210.

[0064] See also Figure 2 In some embodiments, when the fixing component 22 is in the first preset position, the fixing component 22 contacts the first component 210, and the first component 210 is located between the fixing component 22 and the rear mold core 21. When the fixing component 22 is in the second preset position, the fixing component 22 is away from the first cavity and the second cavity.

[0065] Specifically, please combine Figure 5The first preset position is the position where the fixing component 22 is able to contact the first component 210 and fix the first component 210 to the rear mold core 21. Figure 6 The second preset position is the position of the fixing component 22 when it is away from the first cavity so that the first component 210 can move relative to the rear mold core 21, and when the fixing component 22 is away from the second cavity so that the second component 220 can move relative to the rear mold core 21.

[0066] When the first component 210 is generated, the fixing component 22 moves to the first preset position, or the fixing component 22 moves to the first preset position before the first component 210 is generated, so that the fixing component 22 can contact the first component 210 and fix the first component 210 in the rear mold 21, thereby ensuring that when the rear mold 21 is combined with the second front mold 12, the first component 210 will also be driven into the second cavity.

[0067] During injection molding of the second cavity, if the fixing assembly 22 affects the formation of the second component 220, the fixing assembly 22 can be moved to the second preset position before injection molding of the second cavity to ensure smooth injection molding of the second component 220 and facilitate demolding of the target component. If the fixing assembly 22 does not affect the formation of the second component 220, the fixing assembly 22 can be moved to the second preset position after injection molding of the second cavity is completed to ensure smooth demolding of the first component 210 and the second component 220.

[0068] Thus, after the first component 210 is formed, the mold 100 can use the fixing assembly 22 to fix the first component 210 in the rear mold core 21, so that the first component 210 moves with the rear mold core 21 into the second cavity, allowing the injection material in the second cavity to dilute or flatten the gate of the first component 210. At the same time, the fixing assembly 22 can be kept away from the first cavity and the second cavity, ensuring that the fixing assembly 22 does not affect the injection molding of the second component 220 and ensuring smooth demolding of the first component 210 and the second component 220.

[0069] See also Figure 2 In some embodiments, the fixed assembly 22 includes a moving member 221, a driving member and a guide rail 223. The driving member is connected to the moving member 221. The moving member 221 is movably arranged on the guide rail 223. The driving member is used to drive the moving member 221 to move in the guide rail 223. Figure 5 When the moving member 221 is in the first preset position, at least a portion of the moving member 221 extends into the first cavity and contacts the first component 210. The first component 210 is located between the moving member 221 and the rear mold core 21. Figure 6 When the moving member 221 is at the second preset position, the moving member 221 is away from the first cavity and the second cavity.

[0070] Specifically, the fixing assembly 22 includes a movable driving member and a moving member 221. The driving member can drive the moving member 221 to move, and the moving member 221 is used to contact or release the first component 210 and the second component 220. The first preset position is actually the position of the moving member 221 on the guide rail 223 when the moving member 221 can contact the first component 210 and fix the first component 210 to the rear mold core 21. The second preset position is actually the position of the moving member 221 on the guide rail 223 when the moving member 221 is away from the first cavity so that the first component 210 can move relative to the rear mold core 21, and when the moving member 221 is away from the second cavity so that the second component 220 can move relative to the rear mold core 21. When the moving member 221 is in the first preset position, at least a portion of the moving member 221 extends into the first cavity and contacts the first component 210, so that the first component 210 is located between the moving member 221 and the rear mold core 21. When the moving member 221 is at the second preset position, the moving member 221 is away from the first cavity and the second cavity.

[0071] Therefore, the mold 100 can control the movement of the moving member 221 on the guide rail 223 through the driving member, so that after the first component 210 is generated, the moving member 221 can be moved to the first preset position and the first component 210 is fixed in the rear mold core 21, so that when the rear mold core 21 is combined with the second front mold core 12, the first component 210 is also located in the second cavity. Before the second cavity is injected, the mold 100 can control the movement of the moving member 221 on the guide rail 223 through the driving member, so that the moving member 221 is moved to the second preset position, so that the moving member 221 is away from the second cavity, ensuring that the second cavity is successfully injected and the first component 210 and the second component 220 are smoothly demolded.

[0072] In this way, the position of the movable member 221 on the guide rail 223 can be changed by the driving member so that the movable member 221 can fix or release the first component 210, so as to ensure that the first component 210 can be driven into the second cavity on the one hand, and ensure that the movable member 221 does not affect the demolding of the first component 210 and the second component 220 on the other hand.

[0073] See also Figure 2 and Figure 7In some embodiments, there are multiple fixing components 22, such as 2, 4, 7, or 10. The multiple fixing components 22 are arranged around the area of ​​the rear mold core 21 corresponding to the first front mold core 11 and the area of ​​the rear mold core 21 corresponding to the second front mold core 12. That is, the multiple fixing components 22 are arranged around the area of ​​the rear mold core 21 corresponding to the first cavity and the area of ​​the rear mold core 21 corresponding to the second cavity. When the multiple fixing components 22 are all in the first preset position, the multiple fixing components 22 will respectively interfere with different positions of the first component 210, and the first component 210 is located between the fixing components 22 and the rear mold core 21. The fixing effect of the multiple fixing components 22 ensures that the first component 210 can be stably fixed in the rear mold core 21. When the fixing components 22 are in the second preset position, the multiple fixing components 22 are away from the first cavity and the second cavity, ensuring that the fixing components 22 do not affect the formation of the second component 220 or the demolding of the first component 210 and the second component 220.

[0074] The number of the fixing assembly 22 may also be one, so as to reduce the cost of the fixing assembly 22 while ensuring that the fixing assembly 22 can fix the first component 210 .

[0075] See also Figure 2 and Figure 4 In some embodiments, the injection port 221 of the second component 220 is disposed at the rib position 121 of the second front mold core 12 .

[0076] Specifically, the second front mold core 12 is provided with a plurality of ribs 121, also known as reinforcing ribs. Ribs 121 are strip-shaped structures added at specific locations during the design of the mold 100 to increase the strength and rigidity of the mold 100 or the molded part. The injection port 221 of the second component 220 can be located within these ribs 121 of the second front mold core 12. Ribs 121 are generally thick, so injection molding at these ribs reduces the likelihood of surface marks on the second component 220, further enhancing the aesthetics of the second component 220.

[0077] See also Figure 2In some embodiments, the material temperature of the injection molding material of the first component 210 is in the range of [235°C, 240°C], for example, 235°C, 236°C, 237°C, 238°C, 239°C and 240°C. If the material temperature of the injection molding material of the first component 210 is too high, for example, 250°C, the injection molding material will be denatured, thereby affecting the injection molding effect. If the material temperature of the injection molding material of the first component 210 is too low, for example, 225°C, the injection molding material has poor fluidity, making it difficult to inject, thereby affecting the injection molding effect. Therefore, when injecting the first component 210, it is necessary to determine the material temperature of the injection molding material of the first component 210 within the range of [235°C, 240°C] to ensure that the injection molding material will not be deformed and has high fluidity, thereby ensuring a better injection molding effect for the first component 210.

[0078] See also Figure 2 In some embodiments, the temperature difference between the injection molding material of the second component 220 and the injection molding material of the first component 210 is in the range of [15°C, 20°C], i.e., the temperature of the injection molding material of the second component 220 is 15°C to 20°C higher than the temperature of the injection molding material of the first component 210, for example, 15°C, 16°C, 17°C, 18°C, 19°C, and 20°C. If the temperature of the injection molding material of the second component 220 is too low, for example, if the temperature of the injection molding material of the first component 210 is 235°C and the temperature of the injection molding material of the second component 220 is 240°C, the residual gate on the first component 210 cannot be effectively eliminated. If the temperature of the injection molding material of the second component 220 is too high, for example, if the temperature of the injection molding material of the first component 210 is 235°C and the temperature of the injection molding material of the second component 220 is 260°C, the size of the molded second component 220 may be too large. Therefore, the material temperature of the injection molding material of the second component 220 needs to be higher than the material temperature of the injection molding material of the first component 210. The material temperature of the injection molding material of the second component 220 can be determined based on the value range [15°C, 20°C] of the material temperature of the injection molding material of the first component 210 and the difference, so as to ensure that the injection molding material can effectively eliminate the gate of the first component 210 when the second component 220 is injected, and on the other hand, ensure that the size of the final second component 220 meets the requirements.

[0079] See also Figure 2 In some embodiments, the mold temperature of the rear mold core 21 is higher than the temperature of the first front mold core 11 , and the mold temperature of the rear mold core 21 is higher than the temperature of the second front mold core 12 .

[0080] Specifically, if the temperature of the front mold core or the rear mold core 21 is too low, it will easily cause the first component 210 or the second component 220 to shrink. Therefore, the temperature of the front mold core and the rear mold core 21 must be higher. For example, the temperature of the first front mold core 11 and the second front mold core 12 are both 65°C, and the mold temperature of the rear mold core 21 is 75°C.

[0081] After the injection molding of the first component 210 is completed, the first component 210 remains in the rear mold core 21 and is moved to the position of the second cavity through the rear mold core 21. After the injection molding of the first component 210 is completed, the rear mold assembly 20 or the front mold assembly 10 begins to move so that the rear mold core 21 is combined with the second front mold core 12. During the movement, the first component 210 is exposed to the air, so the first component 210 is more likely to shrink and deform. If the shrinkage deformation is too large, the position of the first component 210 in the second cavity will be offset when the second component 220 is injected, resulting in the first component 210 being misaligned after the rear mold core 21 and the second front mold core 12 are closed, thereby affecting the injection molding effect of the mold 100. Therefore, the temperature of the rear mold core 21 must be higher than the temperature of the first front mold core 11 and higher than the temperature of the second front mold core 12. For example, the temperature of the rear mold core 21 is 10 degrees higher than the temperature of the first front mold core 11 and the second front mold core 12, so that the first component 210 will not shrink easily during the movement of the rear mold assembly 20 or the front mold assembly 10, that is, the possibility of shrinkage of the first component 210 is reduced, thereby ensuring the injection molding effect of the mold 100.

[0082] In addition, the movement time of the rear mold assembly 20 or the front mold assembly 10 should not be too long. If the movement time is too long, the first component 210 may be exposed to the air for a long time, causing the first component 210 to shrink, which may lead to loosening, bright lines, color bleeding and other problems during subsequent injection molding. At the same time, the higher the temperature of the first component 210 when the mold is opened, the more likely the residual gate will be diluted by the corresponding injection molding material of the second component 220. Therefore, after the first component 210 is formed, the rear mold assembly 20 or the front mold assembly 10 needs to be moved quickly to reduce the time the first component 210 is exposed to the air, ensure that the first component 210 does not shrink, and facilitate the injection molding material of the second component 220 to flush or dilute the gate of the first component 210.

[0083] See also Figure 2 In some embodiments, the injection molding pressure of the first component 210 is in the range of [90 MPa, 110 MPa], and the injection molding pressure of the second component 220 is in the range of [90 MPa, 110 MPa].

[0084] Specifically, if the injection pressure is too low, the molded part may shrink and deform easily. If the injection pressure is too high, the clamping force between the molded part and the front mold core may be too large, making subsequent demolding difficult. Therefore, the injection pressure needs to be appropriately increased during production. The injection pressure of the first part 210 is in the range of [90MPa, 110MPa], and the injection pressure of the second part 220 is in the range of [90MPa, 110MPa]. The specific injection pressure parameters can be referred to as follows:

[0085] Table (1)

[0086]

[0087]

[0088] The rubber compound of the injection molding machine is pushed into the mold 100 by the screw in the barrel. Each section of the injection represents the position of the screw during extrusion, and the pressure and speed at each position are different.

[0089] As can be seen from Table 1, the injection pressure of the first component 210 during the first stage injection molding is 110 MPa, the injection pressure of the first component 210 during the second stage injection molding is 110 MPa, the injection pressure of the first component 210 during the third stage injection molding is 105 MPa, the injection pressure of the first component 210 during the fourth stage injection molding is 95 MPa, and the injection pressure of the first component 210 during the fifth stage injection molding is 90 MPa. The injection pressure of the second component 220 during the first stage injection molding is 115 MPa, the injection pressure of the second component 220 during the second stage injection molding is 125 MPa, the injection pressure of the second component 220 during the third stage injection molding is 125 MPa, and the injection pressure of the second component 220 during the fourth stage injection molding is 120 MPa.

[0090] In this way, after the first component 210 and the second component 220 are injection molded according to the parameters in the above table, on the one hand, the possibility of deformation of the first component 210 and the second component 220 can be reduced to ensure the injection molding effect of the mold 100; on the other hand, it can ensure that the clamping force between the injection-molded components and the front mold core is not too large, thereby facilitating the demolding of the first component 210 and the second component 220.

[0091] See also Figure 2 In some embodiments, the injection speed of the first component 210 is in the range of [10 mm / s, 28 mm / s], and the injection pressure of the second component 220 is in the range of [10 mm / s, 18 mm / s].

[0092] Specifically, an excessively high injection speed can easily cause the injected material to flip during its injection into the first or second cavity, resulting in defects on the first and second components 210, 220. On the other hand, an excessively low injection speed can easily cause shrinkage in the first and second components 210, 220. Therefore, the injection speed must be appropriately adjusted during production. The injection speed for the first component 210 is in the range of [10 mm / s, 28 mm / s], and the injection pressure for the second component 220 is in the range of [10 mm / s, 18 mm / s]. Specific injection speeds during injection molding can be as shown in Table 1.

[0093] As can be seen from Table 1, the injection speed of the first component 210 during the first stage injection molding is 10 mm / s, the injection speed of the first component 210 during the second stage injection molding is 28 mm / s, the injection speed of the first component 210 during the third stage injection molding is 25 mm / s, the injection speed of the first component 210 during the fourth stage injection molding is 15 mm / s, and the injection speed of the first component 210 during the fifth stage injection molding is 12 mm / s. The injection speed of the second component 220 during the first stage injection molding is 10 mm / s, the injection speed of the second component 220 during the second stage injection molding is 18 mm / s, the injection speed of the second component 220 during the third stage injection molding is 15 mm / s, and the injection speed of the second component 220 during the fourth stage injection molding is 10 mm / s.

[0094] In this way, after controlling the injection molding speed of the first component 210 and the second component 220 according to the parameters in the above table, on the one hand, the possibility of deformation of the first component 210 and the second component 220 can be reduced to ensure the injection molding effect of the mold 100; on the other hand, it can be ensured that the injection molding material will not flip over during the process of rushing into the first cavity or the second cavity, thereby ensuring that there will be no defects on the first component 210 and the second component 220.

[0095] See also Figure 2 In some embodiments, the front mold assembly 10 further includes a first fixing plate 13 and a front template 14, and the rear mold assembly 20 further includes a rear template 24 and a second fixing plate 23. The first fixing plate 13 is connected to the front template 14, and the first front mold core 11 and the second front mold core 12 are installed on the front template 14. The second fixing plate 23 is connected to the rear template 24, and the rear mold core 21 is installed on the rear template 24. The rear template 24 and the front template 14 can move relative to each other so that the rear mold core 21 can be selectively combined with or separated from the first front mold core 11 and the second front mold core 12.

[0096] Specifically, the front mold assembly 10 may also include a first fixed plate 13 and a front mold plate 14. The first front mold core 11 and the second front mold core 12 are both installed in the front mold plate 14. The first fixed plate 13 is connected to the front mold plate 14, so that the injection molding machine can control the movement of the first front mold core 11 and the second front mold core 12 by controlling the movement of the first fixed plate 13. The front mold plate 14 can move toward the rear mold plate 24 to combine with the rear mold plate 24, so that the rear mold core 21 is combined with the first front mold core 11 or the second front mold core 12 to facilitate injection molding. At the same time, the relative position of the rear mold plate 24 when combined with the front mold plate 14 can be multiple, so that the rear mold core 21 can be selectively combined with the first front mold core 11 or the second front mold core 12. The front mold plate 14 can move away from the rear mold plate 24 to separate from the rear mold plate 24, so that the rear mold plate 24 is separated from the first front mold core 11 or the second front mold core 12 to facilitate demolding. At the same time, the front template 14 can stably support the first front mold core 11 and the second front mold core 12, ensuring the stability and precision of the mold 100 during operation. The cooperation between the front template 14 and the front mold core also facilitates the precise positioning of the mold 100, providing convenience for subsequent processing and assembly.

[0097] The rear mold assembly 20 may also include a second fixing plate 23 and a rear mold plate 24. The second fixing plate 23 is connected to the rear mold plate 24, and the rear mold core 21 is installed in the rear mold plate 24. The rear mold plate 24 can stably support the rear mold core 21, ensuring the stability and precision of the mold 100 during operation. The cooperation between the rear mold plate 24 and the rear mold core 21 also facilitates the precise positioning of the mold 100, facilitating subsequent processing and assembly. The second fixing plate 23 can be connected to another part of the injection molding machine, allowing the injection molding machine to control the movement of the rear mold plate 24 through the second fixing plate 23. The rear mold plate 24 can move toward the front mold plate 14 to engage with the front mold plate 14, thereby allowing the rear mold core 21 to engage with the first front mold core 11 or the second front mold core 12 to facilitate injection molding. Furthermore, the rear mold plate 24 can be positioned relative to the front mold plate 14 in a variety of positions, allowing the rear mold core 21 to selectively engage with the first front mold core 11 or the second front mold core 12. The rear template 24 can move away from the front template 14 to separate from the front template 14, so that the rear template 24 is separated from the first front mold core 11 or the second front mold core 12 to facilitate demolding.

[0098] The rear mold plate 24 is movable relative to the front mold plate 14. The movable component can be the front mold plate 14, the rear mold plate 24, or both, without limitation. For example, in some embodiments, the central axis of the front mold plate 14 is aligned with the central axis of the rear mold plate 24, and the rear mold plate 24 is rotatable about the central axis. The distances between the central axes of the first front mold core 11 and the front mold plate 14, the distances between the central axes of the second front mold core 12 and the front mold plate 14, and the distances between the central axes of the rear mold core 21 and the rear mold plate 24 are equal. In this manner, after the rear mold core 21 rotates to the position corresponding to the first front mold core 11, the first front mold core 11 and the rear mold core 21 can be smoothly coupled. After the rear mold core 21 rotates to the position corresponding to the second front mold core 12, the second front mold core 12 and the rear mold core 21 can be smoothly coupled. This allows the rear mold core 21 to be connected to either the first front mold core 11 or the second front mold core 12 by rotating the rear mold plate 24.

[0099] In this way, the injection molding machine can use the first fixed plate 13 to control the movement of the front mold plate 14, or the injection molding machine can use the second fixed plate 23 to control the movement of the rear mold plate 24, thereby driving the rear mold core 21 to selectively engage or separate with the first front mold core 11 and the second front mold core 12, ensuring that the injection molding operation of the mold 100 can proceed smoothly. At the same time, the first fixed plate 13 and the second fixed plate 23 can also improve the stability and precision of the mold 100 during operation.

[0100] See also Figure 2 In some embodiments, the front mold assembly 10 includes a support member 15 and a hot runner plate 16. The support member 15 includes a first end and a second end opposite to each other. The first end of the support member 15 is connected to the front mold plate 14, and the second end of the support member 15 is connected to the hot runner plate 16. The hot runner plate 16 is connected to the first fixed plate 13. The support member 15 is used to support the front mold plate 14 and the hot runner plate 16 to prevent the mold 100 from deforming. The hot runner plate 16 is a device for maintaining the flow state of the molten plastic in the injection mold 100. The first hot nozzle 40 and the second hot nozzle 50 pass through the hot runner plate 16, so that the injection material in the first hot nozzle 40 and the second hot nozzle 50 is always in a flow state, ensuring that the injection molding can be completed smoothly.

[0101] See also Figure 2 In some embodiments, when the second front mold core 12 and the rear mold core 21 are combined, a second cavity is generated, and the fixing assembly 22 is away from the second cavity; the mold 100 includes an ejection assembly 30, which is movably mounted on the support member 15. The ejection assembly 30 can move along the central axis X1 of the mold 100. When the ejection assembly 30 is located at the third preset position, the ejection assembly 30 extends into the second cavity. When the ejection assembly 30 is located at the fourth preset position, the ejection assembly 30 leaves the second cavity.

[0102] Specifically, the third preset position is the position of the ejection assembly 30 when the ejection assembly 30 extends into the second cavity and pushes the target component to move. The fourth preset position is the position of the ejection assembly 30 when the ejection assembly 30 is away from the second cavity.

[0103] The second front mold core 12 is typically provided with ribs 121. Ribs 121 provide a greater clamping force, making the clamping force of the second front mold core 12 greater than that of the rear mold core 21. Furthermore, when the second component 220 is being injected, the fixing assembly 22 is positioned away from the second cavity, that is, the fixing assembly 22 is positioned at the second preset position. Therefore, after the second component 220 is formed, the target component formed by the first component 210 and the second component 220 is positioned on the second front mold core 12.

[0104] The ejector assembly 30 is mounted on the support 15, and the injection molding machine can be connected to the ejector assembly 30 so that the injection molding machine can push the ejector assembly 30. The ejector assembly 30 can move along the center axis X1 direction of the mold 100. When the ejector assembly 30 is located at the third preset position, the ejector assembly 30 extends into the second cavity, so that the ejector assembly 30 can contact the target component in the second cavity and move the target component toward the rear mold core 21, thereby completing the demolding. When the ejector assembly 30 is located at the fourth preset position, the ejector assembly 30 leaves the second cavity and does not come into contact with the second cavity, thereby ensuring that the ejector assembly 30 does not affect the injection molding of the second component 220.

[0105] Thus, when the second component 220 is injection molded, the ejector assembly 30 can be located at the fourth preset position to ensure the injection molding effect of the second component 220. After the second component 220 is injection molded, the ejector assembly 30 can be located at the third preset position to complete demoulding.

[0106] See also Figure 2 In some embodiments, the ejection assembly 30 includes a top block 31 and a top plate 32. Along the direction of the front mold assembly 10 toward the rear mold assembly 20, the distance between the top block 31 and the rear mold core 21 is smaller than the distance between the top plate 32 and the rear mold core 21. The top plate 32 is movably mounted on the support member 15, and the top plate 32 is connected to the top block 31; the top plate 32 can move along the central axis X1 of the mold 100 to drive the top block 31 to move; when the top block 31 is located at the third preset position, the top block 31 extends into the second cavity, and when the top block 31 is located at the fourth preset position, the top block 31 leaves the second cavity.

[0107] Specifically, the third preset position is actually the position of the top block 31 when the top block 31 extends into the second cavity and pushes the target component to move. The fourth preset position is the position of the top block 31 when the top block 31 is away from the second cavity.

[0108] The distance between the ejector block 31 and the rear mold core 21 is smaller than the distance between the ejector plate 32 and the rear mold core 21, that is, the ejector block 31 is a structure in the ejector assembly 30 for contacting and pushing the target component. The ejector plate 32 is movably mounted on the support 15 and connected to the ejector block 31. In one embodiment, the ejector plate 32 can be a single piece, movably mounted on the support 15, one end of the ejector plate 32 is connected to the injection molding machine, and the other end of the ejector plate 32 is connected to the ejector block 31, so that the injection molding machine can push the ejector plate 32 to move, thereby driving the ejector block 31 to move. In another embodiment, the ejector plate 32 includes a first ejector plate 321 and a second ejector plate 322, the first ejector plate 321 and the second ejector plate 322 being connected and both movably mounted on the support 15, the first ejector plate 321 being connected to the injection molding machine, and the second ejector plate 322 being connected to the ejector block 31, so that the injection molding machine can push the first ejector plate 321 to move, thereby driving the second ejector plate 322 and the ejector block 31 to move in turn.

[0109] The top plate 32 can move along the central axis X1 of the mold 100 to drive the top block 31 to move along the direction of the central axis X1 of the mold 100. When the top block 31 is located at the third preset position, the top block 31 extends into the second cavity, the end surface of the top block 31 facing the rear mold core 21 contacts the target component, and pushes the target component toward the rear mold core 21, thereby completing the demolding of the target component. When the top block 31 is located at the fourth preset position, the top block 31 leaves the second cavity, the end surface of the top block 31 facing the rear mold core 21 leaves the second cavity, or conflicts with the second cavity, but does not extend into the second cavity, thereby ensuring that the second cavity can smoothly complete the injection molding, thereby ensuring the injection molding effect.

[0110] In this way, the top plate 32 can be used to push the top block 31 to change the position of the top block 31, ensuring that the top block 31 can push the target component when the target component is generated, so that the target component can be smoothly separated from the second front mold core 12, thereby completing demolding.

[0111] See also Figure 2 In some embodiments, the rear mold core 21 includes multiple rear mold cores 21. When the rear mold core 21 is in a stationary state, the multiple rear mold cores 21 correspond to the first front mold core 11 and the second front mold core 12 respectively.

[0112] In this way, when the front mold assembly 10 and the rear mold assembly 20 are closed, the first cavity and the second cavity can be simultaneously generated. At this time, the first hot nozzle 40 and the second hot nozzle 50 can simultaneously output injection material, allowing the mold 100 to simultaneously produce multiple parts, thereby increasing the production rate of the target parts.

[0113] See also Figure 1 and Figure 2The lampshade 200 provided in the embodiment of the present application includes a first component 210 and a second component 220 made based on the mold 100 of any of the above-mentioned embodiments. It is understood that during the injection molding process of the lampshade 200, the gate of the first component 210 will be diluted or flattened by the injection molding material of the second component 220. The gate of the second component 220 is located in the opaque area of ​​the second component 220, making the gate of the second component 220 invisible to the user. Therefore, it is difficult for the user to observe the gate of any component of the lampshade 200, thereby ensuring the aesthetics of the lampshade 200.
