[0072] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0073] In the description of this application, it should be understood that the terms "center", "length", "up", "down", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this 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 a limitation on this application.

[0074] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0075] In this application, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0076] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0077] During the product production process, in order to improve production efficiency, molded products are usually produced in one piece through a mold. During the use of the mold, high-pressure liquid material needs to be injected into the mold cavity of the mold to form a molded product. However, the high-pressure liquid material will cause a small degree of looseness between the mold components on the mold, thereby affecting the appearance of the molded product and causing a visible parting line to appear on the molded product, affecting the aesthetics and normal use of the molded product. Therefore, how to solve the problem of the appearance of a visible parting line on the molded product, which affects the aesthetics and normal use of the molded product, has become a difficult problem that those skilled in the art urgently need to solve. In order to solve these problems, the present application provides a mold device 100 (such as Figure 1 shown).

[0078] See also Figure 1 The mold device 100 of the embodiment of the present application includes:

[0079] The mold frame 20 includes a first side 21 and a second side 22 opposite to each other; and

[0080] Multiple mold assemblies 10 are arranged on the first side 21 of the mold frame 20 and surround a cavity groove 30 for molding a product. Each mold assembly 10 includes a base 11, which is installed on the first side 21 of the mold frame 20. At least one mold assembly 10 also includes a protrusion 16 extending from the base 11 toward the second side 22 away from the mold frame 20. The protrusion 16 is provided with a connecting hole 161. The protrusion 16 and the connecting hole 161 are both used to connect external equipment.

[0081] Specifically, the mold device 100 mainly includes a mold frame 20 and a plurality of mold assemblies 10. During the use of the mold, under pressure, molten metal, liquefied plastic or other materials are injected into a pre-designed cavity, and a molded product is formed after cooling. The mold frame 20 serves as the basic framework for forming the molded product, and at the same time provides support for other mold assemblies 10 and ensures the stable operation of each component. The mold assembly 10 directly participates in the shaping process of the injected liquid material to form the outer contour of the molded product. The mold device 100 can also be provided with a cooling assembly, which can reduce the mold temperature, accelerate the cooling and solidification of the liquid material, and improve the processing quality of the molded product. In the present application, the mold device 100 is a device for processing and forming a molded product with a spark pattern. During the processing of the molded product with a spark pattern, the mold assembly 10 can reduce the processing steps of the molded product with a spark pattern and improve the production efficiency of the molded product with a spark pattern.

[0082] Specifically, the mold rack 20, also known as a mold storage rack or mold management rack, is a device specifically designed for storing, managing, and protecting molds. In this application, the mold rack 20 includes a first side 21 and a second side 22, opposite to each other. The first side 21 of the mold rack 20 is used to support all mold assemblies 10. Specifically, the mold apparatus 100 includes multiple mold assemblies 10, each of which is disposed on the first side 21 of the mold rack 20. These mold assemblies 10, based on their relative positioning, collectively form a mold cavity 30 for molding a product. When the mold apparatus 100 is connected to an external device, the mold cavity 30 cooperates with the external device to form a mold cavity. Each mold assembly 10 includes a base 11 mounted on the first side 21 of the mold rack 20. At least one mold assembly 10 also includes a protrusion 16 extending from the base 11 toward the second side 22, away from the mold rack 20. The protrusion 16 is provided with a connection hole 161. Both the protrusion 16 and the connection hole 161 are used to connect to an external device. When the mold device 100 is configured for use, the raised portion 16 can cooperate with an external device to prevent the mold assembly 10 from being squeezed and loosened by the liquid material. The connection hole 161 can accurately locate the external device and ensure that the external device is connected to the mold device 100 in the correct position. At the same time, the connection hole 161 can further strengthen the mold assembly 10 of the mold device 100 through its connection with the external device, further preventing the mold assembly 10 from being squeezed and loosened by the liquid material.

[0083] See also Figure 1 In some embodiments of the present invention, at least two mold assemblies 10 include raised portions 16, and at least one mold assembly 10 not having a raised portion 16 is spaced between the mold assemblies 10 having raised portions 16; or

[0084] The mold assembly 10 provided with the protrusion 16 is disposed between adjacent mold assemblies 10 not provided with the protrusion 16 .

[0085] It is understood that, while ensuring that the protrusions 16 can prevent the mold assemblies 10 from loosening, the number of protrusions 16 can be reduced to save material required for producing the mold device 100. Specifically, if there is at least one mold assembly 10 without a protrusion 16 between the mold assemblies 10 provided with protrusions 16, it can be ensured that each mold assembly 10 provided with a protrusion 16 will secure the other two adjacent mold assemblies 10 without a protrusion 16. Alternatively, if a mold assembly 10 provided with a protrusion 16 is placed between adjacent mold assemblies 10 without a protrusion 16, it can be ensured that each mold assembly 10 without a protrusion 16 will be secured by the other two mold assemblies 10 provided with a protrusion 16. Both of these arrangements of the protrusions 16 of the mold assemblies 10 can ensure that the mold assemblies 10 will not loosen under the pressure of the liquid material while reducing the number of protrusions 16, thereby saving material required for producing the mold device 100 and reducing the production cost of the mold device 100.

[0086] See also Figure 1 In some application embodiments, the raised portion 16 includes a top surface 162 away from the mold frame 20, the connecting hole 161 is opened on the top surface 162, and the projection of the raised portion 16 on the base 11 covers the projection of the top surface 162 on the base 11.

[0087] It is understandable that, from the perspective of saving materials required for producing the mold device 100 and reducing the production cost of the mold device 100, the volume of the entire raised portion 16 can be further reduced by reducing the area of ​​the top surface 162 of the raised portion 16 away from the mold frame 20, thereby reducing the production cost of the mold device 100.

[0088] See also Figure 1 In some embodiments of the present invention, the cross-sectional area of ​​the protrusion 16 gradually decreases along the direction from the top surface 162 to the base 11 .

[0089] It is understood that during the manufacturing process of the mold device 100, the shape of the raised portion 16 is set so that the cross-sectional area gradually decreases along the direction from the top surface 162 to the base 11, and the side of the raised portion 16 becomes an inclined slope. When the mold device 100 is configured for use, the mold device 100 needs to be connected to an external device. Compared with the side perpendicular to the top surface 162, the side of the raised portion 16 of the present application will act as a buffer surface at the moment of contact with the external device, that is, by increasing the contact area with the external device, the pressure per unit area is reduced, thereby avoiding the raised portion 16 from being dented or damaged due to collision, thereby extending the service life of the mold device 100.

[0090] See also Figure 1In some application embodiments, multiple mold assemblies 10 include a first mold assembly 101, a second mold assembly 102, a third mold assembly 103, and a fourth mold assembly 104. The first mold assembly 101, the second mold assembly 102, the third mold assembly 103, and the fourth mold assembly 104 sequentially surround and enclose the molding cavity 30, and the first mold assembly 101 and the third mold assembly 103 include a protrusion 16.

[0091] See also Figure 2 In some embodiments, the second mold assembly 102 and / or the fourth mold assembly 104 include:

[0092] The base 11 is provided with a receiving groove 111, a first through hole 112 and a second through hole 113, wherein the first through hole 112 and the second through hole 113 are both connected to the receiving groove 111;

[0093] The first positioning member 12 is located in the receiving groove 111 and is provided with a first mounting groove 121 communicating with the first through hole 112 . The first mounting groove 121 is used to accommodate the first elastic member 122 .

[0094] The second positioning member 13 is located in the receiving groove 111 and has a second mounting groove 131 communicating with the second through hole 113 . The second mounting groove 131 is used to accommodate the second elastic member 132 .

[0095] The shovel 14 can be detachably accommodated in the accommodating groove 111 and connected between the first slider 12 and the second slider 13. When the shovel 14 is accommodated in the accommodating groove 111, the first slider 12 and the second slider 13 are separated by the shovel 14, and the first elastic member 122 and the second elastic member 132 are compressed; when the shovel 14 is removed from the accommodating groove 111, the first elastic member 122 pushes the first slider 12, and the second elastic member 132 pushes the second slider 13, so that the first slider 12 and the second slider 13 are close to each other.

[0096] Specifically, the second mold assembly 102 and / or the fourth mold assembly 104 in the present application include a base 11, a first slider 12, a second slider 13 and a shovel 14. The base 11 is used to support and hold other parts of the mold assembly 10. The base 11 is provided with a receiving groove 111, a first through hole 112 and a second through hole 113. During the use of the mold assembly 10, the mold device 100 will successively undergo two processes of mold closing and demolding. During the mold closing process of the mold device 100, the receiving groove 111 is used to accommodate the first slider 12, the second slider 13 and the shovel 14, and during the demolding process of the mold device 100, the receiving groove 111 is used to accommodate the first slider 12 and the second slider 13. The first through hole 112 and the second through hole 113 are both connected to the receiving groove 111. The operator can set objects used to control the movement of the first slider 12 and the second through hole 113 in the first through hole 112 and the second through hole 113.

[0097] More specifically, during the mold assembly 100's closing process, the first and second sliders 12, 13 must both move away from each other. During the mold assembly 100's demolding process, the first and second sliders 12, 13 must both move toward each other. Therefore, the first slider 12, located within the receiving slot 111, is provided with a first mounting slot 121 that communicates with the first through-hole 112. The first mounting slot 121 accommodates a first elastic member 122. Specifically, an operator can install the first elastic member 122 into the first mounting slot 121 through the first through-hole 112. The first elastic member 122 can be any object with strong elasticity that can return to its original shape after deformation, such as a spring or hydraulic device. During the mold assembly 100's closing process, the shovel 14 shovels into the receiving slot 111 along the closing direction (perpendicular to the bottom surface of the receiving slot 111), thereby moving the first slider 12 away from the second slider 13. This causes the first elastic member 122 to be squeezed and deformed. During the demolding process of the mold device 100, the shovel 14 will separate from the receiving groove 111 along the mold closing direction (a direction perpendicular to the bottom surface of the receiving groove 111). The first elastic member 122 will simultaneously push the first slider 12 toward the second slider 13 while returning to its original position. Similarly, the second slider 13 located in the receiving groove 111 is provided with a second mounting groove 131 that communicates with the second through hole 113. The second mounting groove 131 is used to accommodate the second elastic member 132. That is, the operator can install the second elastic member 132 into the second mounting groove 131 through the second through hole 113. The second elastic member 132 can also be any object with strong elasticity and capable of returning to its original shape after deformation, such as a spring or a hydraulic device. During the mold assembly 100's clamping process, the shovel 14 shovels into the receiving groove 111 along the clamping direction (perpendicular to the bottom surface of the receiving groove 111), thereby moving the second slider 13 away from the first slider 12. This compresses and deforms the second elastic member 132. During the mold assembly 100's demolding process, the shovel 14 disengages from the receiving groove 111 along the clamping direction (perpendicular to the bottom surface of the receiving groove 111). The second elastic member 132 resets and simultaneously pushes the second slider 13 toward the first slider 12.

[0098] Furthermore, the shovel 14 is a detachable portion of the mold assembly 10 and is detachably accommodated within the receiving groove 111. When the shovel 14 is accommodated within the receiving groove 111, the shovel 14 is connected between the first slider 12 and the second slider 13, separating the first slider 12 and the second slider 13 by the shovel 14. The first elastic member 122 and the second elastic member 132 are both in a compressed state. When the shovel 14 is removed from the receiving groove 111, the shovel 14, which has compressed the first slider 12 and the second slider 13, leaves the receiving groove 111. The first elastic member 122 returns to its original state while pushing the first slider 12 toward the second slider 13. The second elastic member 132 also pushes the second slider 13 toward the first slider 12. In other words, the first elastic member 122 and the second elastic member 132 can bring the first slider 12 and the second slider 13 closer to each other. Therefore, during the mold closing or demolding process, the displacement of the two ends of the first slider 12 and the displacement of the two ends of the second slider 13 are the same. Compared with the dovetail slider, the displacement direction of the first slider 12 and the second slider 13 is more single, and it is not easy to get stuck during use, thereby reducing the probability of the raw ear hole being damaged during the demolding process and improving the product yield.

[0099] In certain embodiments, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The shovel 14 includes a first side surface 141 and a second side surface 142 opposite to each other, the first side surface 141 is opposite to the first slider 12, and the second side surface 142 is opposite to the second slider 13;

[0100] A first connecting member 1411 is provided on the first side surface 141 , and a first mating member 1231 is provided on the first side wall 123 of the first slider 12 facing the first side surface 141 . The first connecting member 1411 and the first mating member 1231 cooperate to connect the first slider 12 to the side where the first side surface 141 of the shovel 14 is located; and / or,

[0101] A second connecting member 1421 is provided on the second side surface 142 . A second mating member 1331 is provided on the first side wall 133 of the second slider 13 facing the second side surface 142 . The second connecting member 1421 mates with the second mating member 1331 to connect the second slider 13 to the second side surface 142 of the shovel 14 .

[0102] Specifically, the shovel 14 includes a first side surface 141 and a second side surface 142 facing each other. When the shovel 14 is located within the receiving groove 111, the first side surface 141 of the shovel 14 faces the first slider 12, and the second side surface 142 of the shovel 14 faces the second slider 13. During use of the mold assembly 10, the mold assembly 10 is subjected to significant pressure after the injection of liquid material, such as liquid metal or liquid plastic. Therefore, in the present application, a first connecting member 1411 is provided on the first side surface 141 of the shovel 14, and a first mating member 1231 is provided on the first side wall 123 of the first slider 12 facing the first side surface 141. The first connecting member 1411 cooperates with the first mating member 1231 to connect the first slider 12 to the side of the first side surface 141 of the shovel 14. This enhances the stability of the contact between the shovel 14 and the first slider 12, preventing loosening between the first slider 12 and the shovel 14 during the mold closing process, thereby preventing product quality from being compromised. Similarly, a second connecting member 1421 is provided on the second side 142 of the shovel 14, and a second mating member 1331 is provided on the first sidewall 133 of the second slider 13 facing the second side 142. The second connecting member 1421 cooperates with the second mating member 1331 to connect the second slider 13 to the second side 142 of the shovel 14, thereby enhancing the stability of the shovel 14 and the second slider 13 after contact. The specific shapes of the first connecting member 1411, the first mating member 1231, the second connecting member 1421, and the second mating member 1331 are further described below.

[0103] In certain embodiments, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the first connecting member 1411 is a boss protruding relative to the first side surface 141, the first matching member 1231 is a groove, and the boss is accommodated in the groove; or,

[0104] The first connecting member 1411 is a groove, and the first matching member 1231 is a boss protruding from the first side wall 123 of the first slide member 12 toward the first side surface 141 , and the boss is accommodated in the groove;

[0105] The second connecting member 1421 is a boss protruding relative to the second side surface 142 , and the second matching member 1331 is a groove, and the boss is accommodated in the groove; or,

[0106] The second connecting member 1421 is a groove, and the second matching member 1331 is a boss protruding relative to the first side wall 133 of the second slide member 13 toward the second side surface 142 , and the boss is accommodated in the groove.

[0107] More specifically, in the present application, the first connecting member 1411, the first mating member 1231, the second connecting member 1421, and the second mating member 1331 are configured as bosses or grooves. For example, if the first connecting member 1411 is configured as a boss protruding relative to the first side surface 141, and the first mating member 1231 is configured as a groove, when the shovel 14 shovels into the receiving groove 111 and contacts the first slider 12, the boss can form a mutually interlocking structure with the groove, that is, the first connecting member 1411 and the first mating member 1231 form a mutually interlocking structure, thereby strengthening the connection strength between the shovel 14 and the first slider 12 and preventing loosening during use of the mold assembly 10. Similarly, the first connecting member 1411 can also be set as a groove, and the first matching member 1231 can be set as a boss protruding from the first side wall 123 toward the first side surface 141 relative to the first sliding member 12. When the shovel 14 shovels into the receiving groove 111 and contacts the first sliding member 12, the first connecting member 1411 and the first matching member 1231 can also form a mutually interlocking structure.

[0108] It can be understood that the shape and relationship of the second connecting member 1421 and the second matching member 1331 are similar to the shape and relationship of the first connecting member 1411 and the first matching member 1231. When the second connecting member 1421 is set as a boss protruding relative to the second side surface 142, the second matching member 1331 is set as a groove. When the shovel 14 shovels into the accommodating groove 111 and contacts the second slider 13, the boss can form a mutually interlocking structure with the groove, that is, the second connecting member 1421 and the second matching member 1331 form a mutually interlocking structure, thereby enhancing the connection strength between the shovel 14 and the second slider 13, and avoiding loosening during the use of the mold assembly 10. Similarly, the second connecting member 1421 can also be set as a groove, and the second matching member 1331 can be set as a boss protruding from the first side wall 133 of the second sliding member 13 toward the second side surface 142. When the shovel 14 shovels into the accommodating groove 111 and contacts the second sliding member 13, the second connecting member 1421 and the second matching member 1331 can also form a mutually interlocking structure.

[0109] More specifically, the boss can be a T-shaped boss, and the groove can be a T-shaped groove that can be engaged with the T-shaped boss. The strength of the engagement between the T-shaped boss and the T-shaped groove is higher, which can further enhance the connection stability between the shovel 14, the first sliding member 12 and the second sliding member 13.

[0110] In certain embodiments, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5The shovel 14 includes a first side surface 141 and a second side surface 142 opposite to each other, and a third side surface 143 connecting the first side surface 141 and the second side surface 142. The first slider 12 and the second slider 13 both include a first side wall and a second side wall connected to each other. The first side wall 123 of the first slider 12 and the first side wall 133 of the second slider 13 are respectively opposite to the first side surface 141 and the second side surface 142 of the shovel 14. The mold assembly also includes a fixing member 15, which is installed in the accommodating groove 111. The fixing member 15 is in contact with the third side surface 143 of the shovel 14, the second side wall 124 of the first slider 12 and the second side wall 134 of the second slider 13.

[0111] Specifically, the shovel 14 includes a first side surface 141 and a second side surface 142 that face each other, and a third side surface 143 that connects the first side surface 141 and the second side surface 142. The first slider 12 includes a first side wall and a second side wall that connect together, and the second slider 13 also includes a first side wall and a second side wall that connect together. The first side wall of the first slider 12 and the first side wall of the second slider 13 are opposite the first side surface 141 and the second side surface 142 of the shovel 14, respectively. The mold assembly 10 of the present application also includes a fixing part 15, which is a component used to further reinforce the shovel 14, the first slider 12 and the second slider 13 of the mold assembly 10. The fixing part 15 is installed in the accommodating groove 111 and contacts the third side surface 143 of the shovel 14, the second side wall 124 of the first slider 12 and the second side wall 134 of the second slider 13. After the shovel 14 is shoveled into the accommodating groove 111, the fixing part 15 can ensure that there is no looseness between the shovel 14, the first slider 12 and the second slider 13, thereby improving the overall stability of the mold assembly 10.

[0112] In certain embodiments, see Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The second mold assembly 102 and / or the fourth mold assembly 104 also includes a fixing part 15, which is installed in the accommodating groove 111. The fixing part 15 is in contact with the shovel 14, the second side wall of the first slider 12 and the second slider 13. The first slider 12 and the second slider 13 are respectively provided with a first insert 125 and a second insert 135 at one end away from the fixing part 15. The first insert 125 and the second insert 135 are used to form the raw ear holes on the part to be formed.

[0113] It can be understood that the mold assembly 10 of the present application is a component used to process a watch case and to form part of the outer contour of the watch case. A raw ear hole for mounting a watch strap needs to be provided on the outer contour of the watch case. Specifically, a positioning pin that penetrates the watch strap in a direction perpendicular to the thickness of the strap is provided on the end of the watch strap close to the watch, and the raw ear hole is a hole for accommodating the positioning pin. The positioning hole can connect the watch strap to the watch case by accommodating the two ends of the positioning pin. Therefore, in the present application, a first insert 125 is provided at the end of the first positioning member 12 away from the fixing member 15, and a second insert 135 is provided at the end of the second positioning member 13 away from the fixing member 15. The first insert 125 and the second insert 135 are used to form the raw ear hole on the part to be formed (for example, the watch case to be formed).

[0114] In certain embodiments, see Figure 2 、 Figure 7 and Figure 8 The first insert 125 includes a first setting seat 1251 and a first setting pin 1252 , and the second insert 135 includes a second setting seat 1351 and a second setting pin 1352 ;

[0115] The first mounting seat 1251 is mounted on a side of the first slider 12 that faces away from the first sidewall of the first slider 12 . The first mounting pin 1252 is mounted on the first mounting seat 1251 and protrudes away from the second slider 13 . The extension direction of the first mounting pin 1252 is consistent with the direction of relative movement between the first slider 12 and the second slider 13 .

[0116] The second mounting seat 1351 is installed on the side of the second slider 13 away from the first side wall of the second slider 13, and the second mounting pin 1352 is installed on the second mounting seat 1351 and protrudes in the direction away from the first slider 12. The extension direction of the second mounting pin 1352 is consistent with the direction of relative movement of the first slider 12 and the second slider 13.

[0117] Specifically, the first insert 125 includes a first mounting seat 1251 and a first mounting pin 1252. The first mounting seat 1251 is used to secure the first mounting pin 1252 to the first slider 12. The second insert 135 includes a second mounting seat 1351 and a second mounting pin 1352. The second mounting seat 1351 is used to secure the second mounting pin 1352 to the second slider 13. The first mounting seat 1251 is mounted on the side of the first slider 12 facing away from the first sidewall 123 of the first slider 12. The first mounting pin 1252, which protrudes away from the second slider 13, is mounted on the first mounting seat 1251. The first mounting pin 1252 extends in the same direction as the relative movement of the first slider 12 and the second slider 13. More specifically, during the processing of the part to be molded, the first guide member 12 needs to be used to form an ear hole in the part using a first insert pin 1252 mounted on the first mounting seat 1251. This involves wrapping one end of the first insert pin 1252 with a liquefied material, such as molten metal or liquefied plastic, until the molten metal or liquefied plastic cools and solidifies. After the molten metal or liquefied plastic cools and solidifies, that is, after the part to be molded is formed, the operator needs to remove the part to be molded. However, since one end of the first insert pin 1252 is embedded in the part to be molded, the part cannot be directly removed. The first guide member 12 needs to move toward the second guide member 13 to drive the first insert pin 1252 out of the molded part. Therefore, the extension direction of the first insert pin 1252 needs to be set to coincide with the relative movement direction of the first guide member 12 and the second guide member 13 to prevent damage to the molded part during the process of the first insert pin 1252 withdrawing from the molded part.

[0118] Similarly, a second mounting seat 1351 is mounted on a side of the second guide member 13 facing away from the first sidewall 133 of the second guide member 13. A second mounting pin 1352, projecting away from the first guide member 12, is mounted on the second mounting seat 1351. The extension direction of the second mounting pin 1352 aligns with the direction of relative movement between the first and second guide members 12, 13. More specifically, during the processing of the molded part, the second guide member 13 needs to be processed into a birth hole in the molded part using the second mounting pin 1352 mounted on the second mounting seat 1351. This involves wrapping one end of the second mounting pin 1352 with a liquefied material, such as molten metal or liquefied plastic, until the molten metal or liquefied plastic cools and solidifies. After the molten metal or liquefied plastic cools and solidifies, i.e., after the molded part is formed, the operator needs to remove the molded part. However, because one end of the second mounting pin 1352 is embedded in the molded part, the molded part cannot be directly removed. The second slider 13 needs to move toward the first slider 12 to drive the second insert 1352 out of the molded part. Therefore, the extension direction of the second insert 1352 needs to be set to be consistent with the direction of relative movement between the first slider 12 and the second slider 13 to prevent the second insert 1352 from damaging the molded part during the process of withdrawing the molded part.

[0119] In certain embodiments, see Figure 2 、 Figure 7 、 Figure 8 and Figure 9 A protrusion 114 is provided on the base 11, and the accommodating groove 111 extends to the protrusion 114. The first setting seat 1251 and the second setting seat 1351 are accommodated in the accommodating groove 111 of the protrusion 114, and the first setting pin 1252 and the second setting pin 1352 pass through the two opposite side walls of the protrusion 114.

[0120] Taking the watch case as an example, the position of the ear hole needs to be set on the inner side wall of the groove on the outer surface of the watch case. Therefore, in the present application, a protrusion 114 is provided on the base 11, so that the inner side wall of the groove on the outer surface of the watch case is formed during the molding process of the part to be molded. The first setting seat 1251 and the second setting seat 1351 also need to be accommodated in the accommodating groove 111 of the protrusion 114, and the first setting pin 1252 and the second setting pin 1352 pass through the two opposite side walls of the protrusion 114, so that the ear hole is formed on the inner side wall of the groove on the outer surface during the molding process of the part to be molded.

[0121] In certain embodiments, see Figure 2 、 Figure 7 、 Figure 8 and Figure 9The first insert pin 1252 and the second insert pin 1352 each include a plurality of sub-insertion pins, which have the same extension direction and are connected in sequence in the extension direction. The plurality of sub-insertion pins of the first insert pin 1252 and the second insert pin 1352 each protrude from the two opposite side walls of the protruding portion 114.

[0122] Specifically, during use of the mold assembly 10, the first and second insert pins 1252, 1352 are repeatedly subjected to a pulling force consistent with the direction of relative movement of the first and second guide members 12, 13 during the process of withdrawing from the molded part. Therefore, if the mold assembly 10 is used for an extended period of time, the first and second insert pins 1252, 1352 may break. In this case, an operator is typically required to remove the first and second guide members 12, 13, and replace the insert pins in the first and second insert seats 1251, 1351. In this embodiment, the first and second insert pins 1252, 1352 each include a plurality of sub-pins, each extending in the same direction and connected sequentially in the extension direction. The plurality of sub-pins of the first and second insert pins 1252, 1352 protrude from two opposing side walls of the protruding portion 114. Taking the example that the first inlay pin 1252 and the second inlay pin 1352 both include two sub-inlay pins, during the molding process of the part to be molded, the sub-inlay pins of the first inlay pin 1252 and the second inlay pin 1352 away from the base 11 are configured to form the raw ear holes. In the case that the mold assembly 10 is used for a long time and the inlay pins are broken, only the sub-inlay pins of the first inlay pin 1252 and the second inlay pin 1352 away from the base 11 and configured to form the raw ear holes will break. At this time, since the first inlay pin 1252 and the second inlay pin 1352 are also provided with sub-inlay pins protruding from the two opposite side walls of the protrusion 114, the operator can repair or replace the damaged sub-inlay pins without disassembling the first guide member 12 and the second guide member 13. This embodiment can reduce the number of times the mold assembly 10 is disassembled and repaired during use, thereby improving the processing efficiency of the part to be molded.

[0123] It can be understood that in some embodiments, the base 11 is also provided with a first needle hole 115 for accommodating the first inlay needle 1252 and a second needle hole 116 for accommodating the second inlay needle 1352. The aperture of the first needle hole 115 is larger than the diameter of the first inlay needle 1252, and the aperture of the second needle hole 116 is larger than the diameter of the second inlay needle 1352.

[0124] In certain embodiments, see Figure 2 、 Figure 4 、 Figure 5 and Figure 9A first buffer corner 126 is formed between two adjacent side walls of the first slider 12, and a first matching corner 117 is formed on the two inner side walls of the base 11. When the first slider 12 and the second slider 13 are separated by the shovel 14, the first buffer corner 126 cooperates with the first matching corner 117; and / or,

[0125] A second buffer corner 136 is formed between two adjacent side walls of the second slider 13, and a second matching corner 118 is formed on the two inner side walls of the base 11. When the second slider 13 and the second slider 13 are separated by the shovel 14, the second buffer corner 136 cooperates with the second matching corner 118.

[0126] It is understood that when the first slider 12 and the second slider 13 are separated by the shovel 14, the first slider 12 will move away from the second slider 13, and the second slider 13 will move away from the first slider 12. During the movement of the first slider 12 and the second slider 13, both the first slider 12 and the second slider 13 will collide with the inner sidewalls of the receiving groove 111. In this embodiment, a first buffer corner 126 is formed between two adjacent sidewalls of the first slider 12, and first matching corners 117 are formed on the two inner sidewalls of the base 11. When the first slider 12 collides with the inner sidewall of the receiving groove 111, the first buffer corner 126 collides with the first matching corner 117, thereby reducing the unit area pressure of the first slider 12 when colliding with the base 11, thereby preventing damage to the first slider 12 or the base 11 due to the collision. Similarly, a second buffer corner 136 is formed between two adjacent side walls of the second positioning member 13, and a second matching corner 118 is formed on the two inner side walls of the base 11. When the second positioning member 13 collides with the inner side wall of the accommodating groove 111, the second buffer corner 136 will collide with the second matching corner 118, thereby reducing the unit area pressure when the second positioning member 13 collides with the base 11, thereby avoiding damage to the second positioning member 13 or the base 11 due to collision.

[0127] In certain embodiments, see Figure 2 、 Figure 4 、 Figure 5 and Figure 9 A first buffer slope 127 is formed on a side wall of the first slider 12, and a first matching slope 1191 is formed on an inner side wall of the base 11. When the first slider 12 and the second slider 13 are separated by the shovel 14, the first buffer slope 127 contacts the first matching slope 1191; and / or

[0128] A second buffer slope 137 is provided on a side wall of the second slider 13 , and a second matching slope 1192 is formed on an inner side wall of the base 11 . When the second slider 13 and the second slider 13 are separated by the shovel 14 , the second buffer slope 137 contacts the second matching slope 1192 .

[0129] Specifically, when the first slider 12 and the second slider 13 are separated by the shovel 14, the first slider 12 will move away from the second slider 13, and the second slider 13 will move away from the first slider 12. During the movement of the first slider 12 and the second slider 13, both the first slider 12 and the second slider 13 will collide with the inner sidewall of the receiving groove 111. In this embodiment, a first buffer slope 127 is formed on one sidewall of the first slider 12, and a first mating slope 1191 is formed on one inner sidewall of the base 11. When the first slider 12 collides with the inner sidewall of the receiving groove 111, the first buffer slope 127 collides with the first mating slope 1191, thereby reducing the unit area pressure of the first slider 12 when colliding with the base 11, thereby preventing damage to the first slider 12 or the base 11 due to the collision. Similarly, a second buffer slope 137 is provided on a side wall of the second positioning member 13, and a second matching slope 1192 is formed on an inner side wall of the base 11. When the second positioning member 13 collides with the inner side wall of the accommodating groove 111, the second buffer slope 137 will collide with the second matching slope 1192, thereby reducing the unit area pressure when the second positioning member 13 collides with the base 11, thereby avoiding damage to the second positioning member 13 or the base 11 due to the collision.

[0130] In certain embodiments, see Figure 2 and Figure 3 The shovel 14 has at least one connecting slot 144, which is used to connect to external equipment.

[0131] Specifically, during the mold closing process, the external device contacts and controls the shovel machine 14 through the positioning groove to shovel into the receiving groove 111 along the mold closing direction (the direction perpendicular to the bottom surface of the receiving groove 111). During the demolding process, the external device contacts and controls the shovel machine 14 through the positioning groove to exit the receiving groove 111 along the mold closing direction (the direction perpendicular to the bottom surface of the receiving groove 111).

[0132] In certain embodiments, see Figure 1 and Figure 10 The first side 21 of the mold frame 20 includes a plurality of component slots 211 , and the plurality of mold assemblies 10 are respectively accommodated in the plurality of component slots 211 ;

[0133] At least one inner wall of the mold assembly 10 is in contact with a corresponding inner wall of the assembly groove 211 .

[0134] It is understandable that by arranging the mold assembly 10 in the assembly groove 211, it is possible to prevent the mold assembly 10 from loosening during use of the mold device 100, thereby preventing visible parting lines from appearing on the molded product.

[0135] In certain embodiments, see Figure 1 and Figure 10 , the bottom surface 2111 of the component groove 211 is provided with at least one positioning member 2112 , and the side of the mold assembly 10 that contacts the bottom surface 2111 of the component groove 211 is provided with at least one matching member 17 ;

[0136] When the mold assembly 10 is accommodated in the corresponding assembly groove 211 , the positioning member 2112 cooperates with the matching member 17 to limit the mold assembly 10 .

[0137] Specifically, the positioning member 2112 can further prevent the mold assembly 10 from becoming loose during use of the mold device 100 by interlocking with the matching member 17, thereby preventing visible parting lines from appearing on the molded product.

[0138] In certain embodiments, see Figure 1 and Figure 10 , the positioning member 2112 is a groove, the matching member 17 is a boss protruding relative to the bottom surface 2111 of the component groove 211, and the boss is accommodated in the groove; or,

[0139] The positioning member 2112 is a boss protruding relative to the bottom surface 2111 of the component slot 211 , and the matching member 17 is a groove, and the boss is accommodated in the groove.

[0140] In certain embodiments, see Figure 1 and Figure 10 The groove includes a first sub-groove 2113 and a second sub-groove 2114 that are connected. A step surface is formed at the junction of the first sub-groove 2113 and the second sub-groove 2114. The step surface is used to limit the mold assembly 10 from escaping from the assembly groove 211.

[0141] Specifically, since the first sub-groove 2113 and the second sub-groove 2114 are connected to form a step surface, the side wall of the groove is no longer a complete plane, and the groove can prevent the mold assembly 10 from slipping away from the cavity groove 30, thereby further preventing the mold assembly 10 from becoming loose when the mold device 100 is configured for use. Figure 10 It can be seen that the bottom surface 2111 of each component slot 211 is provided with at least one positioning hole, and these positioning holes can also further prevent the mold assembly 10 from loosening during use.

[0142] In some embodiments, the multiple mold components 10 of the mold device 100 are shaped by a three-dimensional copper rod. Compared with the method of using multiple component copper rods for multiple processing, the three-dimensional copper rod can complete the shape of all mold components 10 at one time, thereby avoiding the problem of excessive cumulative error in the size of the mold device 100 caused by multiple processing during discharge machining.

[0143] In summary, in the mold device 100 according to the embodiment of the present application, the mold device 100 includes a mold frame 20 and a plurality of mold assemblies 10. The mold frame 20 is used as the base of the entire mold device 100 and is used to support all mold assemblies 10 of the mold device 100. Therefore, the mold assemblies 10 are all arranged on the first side 21 of the mold frame 100. The mold assemblies 10 enclose a cavity 30 for molding a product. Each mold assembly 10 includes a base 11, which is mounted on the first side 21 of the mold frame 20. At least one mold assembly 10 also includes a raised portion 16 extending from the base toward a second side 22 away from the mold frame. The raised portion 16 is provided with a connection hole 161. The raised portion 16 and the connection hole 161 are both used for connecting to external equipment. When the mold device is closed with an external device, the protrusion 16 can be connected to the external device, thereby fixing the mold assembly 10, and the connection hole 161 can also be connected to the external device to further strengthen the connection stability between the protrusion 16 of the mold assembly 10 and the external device, thereby avoiding the appearance of a visible closing line on the molded product processed by the mold device 100, and avoiding affecting the aesthetics and normal use of the molded product.

[0144] The technical features of the above embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there are no contradictions in the combination of these technical features, they should be considered to be within the scope of this specification. At the same time, other implementation methods can be derived from the above embodiments, so that structural and logical replacements and changes can be made without departing from the scope of this disclosure.

[0145] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
