Detailed Description of the Embodiments

[0033] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0034] In the prior art, the precision stamping and stretching processes of laptop computers are key steps to ensure the aesthetic appearance and structural stability of the products. These processes are crucial for achieving the fine lines, smooth surfaces, and precise dimensions of laptop computer casings. However, in the field of laptop computer casing manufacturing, the traditional stamping and stretching processes face a series of challenges, especially in the die repair work, where significant problems exist. First of all, the die repair cost is high. When the die needs to be adjusted in size or repaired, manufacturers often need to scrap the existing die and invest a large amount of money to remanufacture the entire master die. This process not only increases the production cost but also extends the product's time to market, affecting market competitiveness. Frequent die replacement may also lead to material waste, further exacerbating the cost problem. Secondly, the die repair cycle is long. During the die manufacturing and adjustment process, complex design, machining, and testing processes are required, which usually take several weeks or even months. During this period, the production line may be idle waiting for the die, resulting in a significant drop in production efficiency. In addition, the unevenness of the appearance R angle is also a prominent problem. At the corner positions of laptop computer casings, due to the change in material thickness, the forming of the R angle is often difficult to control, resulting in product appearance inconsistency and reduced aesthetic appeal. This unevenness may not be very obvious visually, but it may affect the user's hand feeling and the durability of the device in actual use. To solve these problems, manufacturers need to continuously optimize die design and manufacturing processes. This includes using advanced die materials, introducing precision machining technologies, and developing more efficient die adjustment methods. Through these measures, the product quality can be significantly improved, material waste during die repair can be reduced, the production cycle can be shortened, thereby enhancing production efficiency and market response speed. At the same time, manufacturers also need to pay attention to the sustainability of the die. By designing reusable and easy-to-maintain dies, the impact on the environment can be reduced, and the long-term cost during die repair can be lowered.

[0035] To solve the problem of uneven R - corners during the repair of existing die - casting molds, the embodiments of the present application provide a die - casting mold and a die - casting device for a laptop computer housing. A female mold is provided, and a first assembly port is opened in the female mold. At the same time, a male mold is provided. The male mold includes a male - mold body and a back - extrusion punch. The male - mold body is aligned with the female mold. An inner - ejector is provided in the first assembly port. There is a die - casting space between the male - mold body and the inner - ejector and between the male - mold body and the female mold. The die - casting space enables the product material to be shaped according to the set product size requirements. The back - extrusion punch is arranged at the corner of the male - mold body for repairing the R - corner. Among them, the back - extrusion punch is provided with a tip and a contact part. The tip is attached to the corner of the male - mold body and is aligned with the die - casting space between the male - mold body and the female mold. The contact part is adjacent to the tip and is arranged opposite to the female mold, which can improve the R - corner by the back - extrusion punch, avoid the waste of materials due to unsatisfactory product forming, and solve the problem of uneven R - corners during the repair process. In addition, a second assembly port is provided in the female mold, and the first assembly port and the second assembly port are connected. A insert is detachably installed in the second assembly port. According to the requirements of the product size, the size of the second assembly port can be changed by using the insert in the second assembly port, and correspondingly, the size of the female mold is also changed, thus saving the cost of replacing the entire female mold.

[0036] A die - casting mold and a die - casting device for a laptop computer housing provided by the embodiments of the present application aim to solve the above - mentioned technical problems in the prior art.

[0037] The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above - mentioned technical problems with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0038] Figure 1 The structural schematic diagram of the die - casting mold provided by the embodiments of the present application is as Figure 1 shown. The die - casting mold includes a female mold 100 and a male mold 200. Among them,

[0039] Female mold 100, the female mold 100 can be a molding tool for producing plastic products, metal castings or other materials. The female mold 100 can be used in conjunction with the male mold 200 to complete the stretching and shaping of the product material. In the embodiment of the present application, the female mold 100 can be a mold for making a notebook shape. A first assembly port and a second assembly port can be provided in the female mold 100. The first assembly port and the second assembly port can refer to two openings on the female mold for connecting with the male mold. The first assembly port and the second assembly port are connected. A insert is detachably installed in the second assembly port. The shape of the insert can be consistent with that of the second assembly port and is used to connect with the male mold after being inserted into the second assembly port. Thus, when the notebook size is a commonly used size in engineering settings, the first assembly port is used to cooperate with the male mold 200 to complete the extrusion and stretching of the product material 400. When the notebook size changes, instead of scrapping the original female mold 100, only a replaceable insert needs to be installed in the second assembly port to adapt to the new size requirements, reducing the material cost;

[0040] Male mold 200, the male mold 200 can be the mold part opposite to the female mold 100 and is used to form the shape and features of the casting. In the embodiment of the present application, the male mold 200 includes a male mold body 210 and a back-extrusion punch 220. The male mold body 210 is aligned with the female mold 100 to enhance the effect of product shaping. And an inner stripping part 300 is provided in the first assembly port. A die-casting space is left between the male mold body 210 and the inner stripping part 300 and between the male mold body 210 and the female mold 100. The inner stripping part 300 is used to form complex shapes inside the product, such as holes, grooves or complex geometric shapes. The inner stripping part 300 can be made of steel, aluminum alloy, composite materials, etc. The die-casting space is a shaping space for the material to shape the material into a specified shape. Among them, positioning posts 310 are added to the inner stripping part 300, which can make the cooperation between the insert and the inner stripping part 300 more precise, ensuring the alignment accuracy during the die-casting process. The design of the positioning posts 310 not only improves the assembly efficiency of the mold but also helps to reduce errors in production, thereby improving the quality and consistency of the die-casting mold. In some embodiments, positioning posts 310 are also added to the male mold body 210 to ensure the precise alignment of the male mold body 210 and the female mold 100 during the die-casting process.

[0041] In some embodiments, a tip 221 and a contact portion 222 are provided on the back-extrusion punch 220. The tip 221 is attached to the corner of the male mold body 210. After an insert is assembled on the second assembly port provided on the female mold 100, the tip 221 is aligned with the die-casting space left between the male mold body 210 and the insert. Thus, the product material 400 can be pressed into the die-casting space by the tip 221, enhancing the shaping effect of the R corner. The contact portion 222 is adjacent to the tip 221 and is disposed opposite to the insert. The contact portion 222 is used to strengthen the back-extrusion punch 220 and prevent the problem that the back-extrusion punch 220 breaks due to excessive extrusion pressure.

[0042] In the embodiment of the present application, the thickness of the tip 221 is the same as the thickness of the die-casting space between the male mold body 210 and the insert. The thickness of the die-casting space between the male mold body 210 and the insert refers to the gap between the male mold body 210 and the insert. The thickness of the tip 221 is consistent with the size of the die-casting space between the male mold body 210 and the insert, which can ensure that when the female mold 100 moves downward, one side of the tip 221 can fit with the edge of the male mold 200, and the other side of the tip 221 fits with the second assembly port. The tip 221 can penetrate into the gap between the male mold body 210 and the insert, enhancing the effect of mold extrusion.

[0043] In the embodiment of the present application, the male mold body 210 is installed above the workbench 500 through a buffer member 230. The buffer member 230 can refer to a nitrogen spring, a rubber pad, a hydraulic buffer, etc., which is used to reduce the descending speed of the male mold 200 when the male mold 200 is extruded, and cooperate with the female mold 100 and the inner stripping member 300 to extrude and stretch the product material 400 together. Moreover, a buffer space is left between the male mold body 210 and the workbench 500. The buffer space is used to slow down the impact force when the mold is closed, further reducing component wear, extending the life of the mold, facilitating mold adjustment and maintenance, and at the same time ensuring operation safety and reducing noise and vibration, thereby improving the overall production efficiency and the stability of the mold. In addition, by setting the length of the back-extrusion punch 220 to be greater than the height of the buffer space, it can be ensured that the back-extrusion punch 220 can completely enter the buffer area when inserted into the jack, so as to make full use of the buffer space to absorb the impact force and protect the mold.

[0044] In some embodiments, in order to improve the compressive resistance of the back-extrusion punch 220, an arc-shaped surface transition is provided between the tip 221 and the contact portion 222 of the back-extrusion punch 220. The arc-shaped surface is used to make the force on the back-extrusion punch 220 uniform. When the female mold 100 and the male mold 200 perform extrusion operations, the tip 221 of the back-extrusion punch 220 in the die-casting space is not easily broken, reducing the possibility of loss of the back-extrusion punch 220, improving the success rate of product shaping, further saving raw materials, and reducing the cost during the mold repair process.

[0045] In the embodiment of the present application, a buffer protection layer is further provided on the contact portion 222. The buffer protection layer can be made of wear-resistant and impact-resistant materials, such as rubber, polyurethane or other high-performance plastics. By using the buffer protection layer, the impact force and pressure when the master die 100 presses downward are reduced, the damage caused by the direct contact between the master die 100 and the backward extrusion punching part 220 is reduced, the service life of the die is prolonged, and the die repair cost is further reduced.

[0046] Figure 2 It is a top view schematic diagram of the male die of the die-casting mold provided by the embodiment of the present application. As Figure 2 shown, the backward extrusion punching part 220 is arranged at the corner of the male die body 210. The corner can refer to the R corner for processing product materials. The R corner of the male die body 210 corresponds to the R corner of the female die. The backward extrusion punching part 220 can be made of materials with good elasticity and wear resistance, such as stainless steel or aluminum alloy. The backward extrusion punching part 220 is used to improve the uneven problem of the too large R corner of the notebook, and being arranged at the corner can also enhance the pressure at the corner and reduce the bubbles and voids in the formed notebook.

[0047] Figure 3 It is a schematic diagram of the die-casting process of the die-casting mold provided by the embodiment of the present application. As Figure 3 shown, a die-casting space is formed between the female die 100, the inner stripping part 300 and the male die body 210. The product material 400 is in the die-casting space. The edge of the product material 400 abuts against the tip 221 on the backward extrusion punching part 220, so that the shaping effect at the corner is enhanced, which is more in line with the ideal product design, and it also avoids material waste caused by the non-compliance of product manufacturing.

[0048] Figure 4 It is a schematic diagram of the installation of the backward extrusion punching part provided by the embodiment of the present application. As Figure 4As shown, in the embodiment of the present application, the male mold body is installed on the workbench 500. The workbench 500 can refer to an operating table fixedly installed on the ground. The backward extrusion punch 220 is detachably inserted into the upper side of the workbench 500 and connected to the male mold body. When it is necessary to improve the corners of the raw materials of the notebook, the backward extrusion punch 220 is installed on the workbench 500 and arranged in conformity with the male mold body, and the product material is extruded by cooperating with the female mold and the male mold. In some embodiments, a jack 510 is provided on the workbench 500, and a pressure touch switch 520 is provided at the bottom of the jack 510. The backward extrusion punch 220 is inserted into the jack 510 and abuts against the pressure touch switch 520. The pressure touch switch 520 is also connected to the driving member of the female mold. When the backward extrusion punch 220 is not correctly placed into the jack 510, the pressure touch switch 520 will not be triggered, and the female mold will not move, reducing the possibility of damaging the raw materials due to the incorrect placement of the backward extrusion punch 220. At the same time, when the female mold is pressed down and the extruded product material touches the tip of the backward extrusion punch, if there is a possibility of damage to the product material and the backward extrusion punch 220 when the extrusion degree is too deep, the pressure touch switch 520 transmits the information of stopping the operation to the driving member of the female mold, reducing the possibility of accidents.

[0049] Figure 5 Schematic diagram of the structure of the female mold 100 of the die-casting mold provided by the embodiment of the present application, as Figure 5 As shown, in the embodiment of the present application, an assembly hole 140 is formed on the female mold 100. The assembly hole 140 is a hole position on the female mold 100 for positioning and fixing the insert 130, and can be designed according to the size and shape of the insert 130. The insert 130 is connected to the second assembly port 120 through a detachable fixed connection with the assembly hole 140.

[0050] In some embodiments, when it is necessary to change the size of the second assembly port 120 to meet the requirements of the product size, first place the insert 130 on the second assembly port 120 of the female mold 100 to ensure that it is aligned with the assembly hole 140 on the second assembly port 120, then insert a dowel pin for preliminary positioning, and then tighten the screw to fix the insert 130. Finally, check the fixing conditions of the screw and the dowel pin to ensure that the insert 130 is firmly and correctly installed on the second assembly port 120 of the female mold 100, so as to meet the requirements of the new product size.

[0051] In the embodiment of the present application, the first assembly port 110 and the second assembly port 120 form a stepped hole. The depths of the first assembly port 110 and the second assembly port 120 can be different. The first assembly port 110 is shallower and the second assembly port 120 is deeper. When the insert 130 is loaded, the shallower first assembly port 110 allows the insert 130 to be precisely positioned in the initial stage, ensuring that the insert 130 is aligned with the mold. Then, the insert 130 is pushed into the deeper second assembly port 120, which can gradually increase the fixing force to ensure the stability of the insert 130 in the mold. The insert 130 is snap-fitted at the step of the stepped hole, providing a stable fixing method and also allowing the insert 130 to be easily disassembled when the notebook size changes, facilitating the maintenance and replacement of the insert 130. At the same time, the inner stripper is snap-fitted with the insert 130, so that the inner stripper maintains an accurate relative position with the insert 130 when the mold is closed, ensuring precise cooperation during the notebook forming process. The snap-fitting between the inner stripper and the insert 130 also helps to improve the overall rigidity and stability of the mold, reducing the deformation that may occur during the high-pressure forming process.

[0052] The embodiment of the present application also provides a die-casting device for a notebook computer housing. The die-casting device for the notebook computer housing may include the die-casting mold in the embodiment of the present application. Thus, the die-casting device for the notebook computer housing can ensure the consistency and quality of the notebook computer housing by precisely controlling the die-casting space and material fluidity. At the same time, through the general design of the mold and using different product requirements of the inserts, material waste is reduced and the material utilization rate is improved. In addition, the detachable back-extrusion punch simplifies the maintenance and replacement of the mold, thereby reducing the production cost, enhancing the durability of the mold, and extending the service life. Generally speaking, the introduction of this die-casting mold makes the production of the notebook computer housing more efficient and economical, while enhancing the market competitiveness of the product.
