Figure 5 for Figure 4 The cross-section of AA in the Figure 6 for Figure 4 Cross-section of the BB.

[0043] The mold insert proposed in the embodiment of the utility model comprises:

[0044] The backing plate 100 includes a first plate surface 102, a second plate surface 104 and a circumferential side wall 106. The first plate surface 102 and the second plate surface 104 are arranged opposite to each other with a spacing. The circumferential side wall 106 is connected around the outer edge of the first plate surface 102 and the outer edge of the second plate surface 104. The backing plate 100 also forms a first flow channel 108 for the circulation of coolant.

[0045] The mold core 200 is an integrally formed component. One end of the mold core 200 is connected to the first plate surface 102. The mold core 200 is provided with at least two grooves 200a on one side facing the backing plate 100. A partition 200b is formed between any two adjacent grooves 200a. The partition 200b is penetrated by a second flow channel 202 that connects the two adjacent grooves 200a for the circulation of coolant.

[0046] At least two connecting blocks 300, one end of each connecting block 300 is connected to the backing plate 100, and the other end is respectively inserted into the groove 200a, and at least two connecting blocks 300 form a third flow channel 302 for the circulation of the coolant;

[0047] The first flow channel 108 , the third flow channel 302 , and the second flow channel 202 are sequentially connected to form a cooling channel.

[0048] In the embodiment of the utility model, the backing plate 100, the mold core 200 and the connecting block 300 together constitute an improved mold insert system; wherein the backing plate 100 mainly serves as a mounting base for the connecting block 300 and the mold core 200, and is connected to the mold base 502 at the same time, and forms a first flow channel 108 for the circulation of the coolant. The material of the backing plate 100 can generally be a high temperature resistant and high strength material, such as high temperature alloy steel or ceramic material. In addition, the shape of the backing plate 100 can be designed in a variety of ways, but generally speaking, it is mainly set to a shape that matches the mold core 200, which is conducive to ensuring the accuracy and consistency of the overall mold.

[0049] The mold core 200 in this embodiment directly affects the quality of the molded part. One end of the mold core 200 is connected to the backing plate 100, and the other end forms a complete and seamless molding surface. The mold core 200 can be made of hardened tool steel or wear-resistant alloy to enhance durability and wear resistance. The groove 200a of the mold core 200 is designed to form a second flow channel 202 to optimize the cooling effect.

[0050] The connection block 300 is inserted into the groove 200a of the mold core 200, one end of which is connected to the pad 100, and the other end is connected to the molding surface. In this embodiment, the design of the connection block 300 can enhance the strength of the mold core 200. For example, after the connection block 300 enters the groove 200a, it can fill at least a portion of the groove 200a, so that the contact area with the mold core 200 is increased, thereby reducing the presence of cavities inside the mold core 200 and providing additional support for the mold core 200. This support effect can make the mold core 200 more stable during the molding process. As for the selection of the material of the connection block 300, a material with good thermal conductivity, such as copper alloy, can be used to promote uniform distribution of heat.

[0051] As for the formation process of the first flow channel 108 , the second flow channel 202 , and the third flow channel 302 , high-precision CNC machining can be used to ensure the accuracy of the flow channels and the smooth flow of the fluid.

[0052] In this embodiment, the assembly design of the groove 200a inside the mold core 200 and the connecting block 300 on the backing plate 100 allows the two to be disassembled and processed separately, making it easier to form the first flow channel 108, the second flow channel 202, and the third flow channel 302. Because they can be disassembled separately, the size and shape can be more accurately controlled when processing the flow channel, thereby improving processing efficiency and quality.

[0053] Since the mold core 200, the connecting block 300 and the backing plate 100 can be separated to process the flow channel separately, the working surface of the mold core 200 can be designed to be a complete molding surface without gaps. This means that the surface of the molded part will be smoother and there will be no marks or defects caused by improper mold splicing. This is especially important for parts that require high appearance quality.

[0054] In this embodiment, the connection block 300 is provided so that it can provide additional support for the mold core 200 after being assembled with the groove 200a of the mold core 200, thereby enhancing the internal strength of the mold core 200. Such support makes the mold core 200 more stable when subjected to high pressure during the molding process, thereby reducing the possibility of deformation.

[0055] After assembly, the connecting block 300, the mold core 200 and the backing plate 100 form an integral mold, in which the cooling channel is continuous and closed. This ensures that the coolant can flow smoothly and unimpeded, improves the cooling efficiency, helps control the temperature during the molding process, reduces thermal stress, and improves the structural integrity of the part.

[0056] It should be noted that in the prior art, the punching of holes on the small inserts will lead to reduced strength, mainly because the flow channels formed by these punching holes are close to the molding surface, which may weaken the structural integrity of the inserts, causing the molding surface to collapse due to the presence of the flow channels after being hot-pressed. In contrast, in this embodiment, at least two grooves 200a are opened on the mold core 200, and a second flow channel connecting these grooves 200a is set in the partition to provide circulation of coolant (compared with the prior art, the flow channel is a certain distance away from the molding surface). This design not only avoids the problem of the insert gap directly facing the plate surface in the prior art, but also because the molding surface of the mold core 200 is integrally formed, there is no gap. After installation, the connecting block 300 fills most of the space of the groove 200a (in this embodiment, there may be a gap of a preset size between the connecting block 300 and the groove 200a, and the gap is used for the flow of coolant), which not only enhances the internal strength of the mold core 200, but also improves the durability and molding quality of the overall mold. The formation of the flow channel can also facilitate the circulation of coolant in the mold core. In general, this embodiment significantly improves the performance and efficiency of the mold through the innovative flow channel design and mold core 200 structure.

[0057] In the technical solution of this embodiment, the mold core 200 is an integrally formed component, rather than being formed by splicing a plurality of inserts, thereby avoiding the occurrence of undesirable phenomenon of part seam crushing, and is conducive to improving the precision and overall strength of the mold. A first flow channel 108 is formed on the backing plate 100, a second flow channel 202 is formed on the mold core 200, and a third flow channel 302 is formed by a connecting block 300 for the circulation of coolant. At least two connecting blocks 300 are provided on the first plate surface 102 of the backing plate 100, and these connecting blocks 300 cooperate with at least two grooves 200a of the mold core 200 facing the backing plate 100, in order to enhance the internal strength of the mold core 200. After the mold core 200 and the backing plate 100 are assembled, these connecting blocks 300 are respectively inserted into the grooves 200a, and the formed third flow channel 302 is connected to the first flow channel 108 and the second flow channel 202 to form a cooling channel together; in this way, not only the internal strength of the mold core 200 is enhanced, but also the cooling flow channel is effectively formed through the connection of the flow channels, thereby controlling the temperature during the molding process and ensuring the molding quality and efficiency.

[0058] Continue reading Figure 1 In this embodiment, the end surface of the mold core 200 facing away from the pad 100 is a plane;

[0059] And / or, the backing plate 100 is an integrally formed component, and each connecting block 300 is an integrally formed component.

[0060] In this embodiment, the end surface of the mold core 200 facing away from the backing plate 100 is designed to be a plane, and the mold core 200 is a component manufactured by an integrated molding process. Specifically, the end surface of the mold core 200 facing away from the backing plate 100 is a plane, which can be achieved by grinding or CNC machining technology. This machining method can ensure the flatness and verticality of the end surface, so as to achieve close cooperation with the backing plate 100 during assembly.

[0061] In addition, the groove 200a and the mold core 200 may be integrally formed by a casting or forging process, which not only ensures the structural consistency between the groove 200a and the mold core 200, but also improves the mechanical strength and durability of the overall component.

[0062] In this embodiment, the mold end surface is designed as a complete plane, which helps to increase the contact area between the mold and the pad 100, thereby enhancing the stability and sealing of the assembly. In addition, the one-piece molding design of the mold core 200 eliminates the gaps and unevenness that may be caused by the splicing of multiple parts, thereby improving the quality of the molded parts. In addition, the one-piece mold core 200 is more solid when subjected to the pressure during the molding process, reduces the possibility of deformation, and extends the service life of the mold. And with the cooperation of the connecting block 300, the internal strength of the mold core 200 can be further enhanced.

[0063] Continue reading Figure 3 In this embodiment, at least two grooves 200a are spaced apart and distributed along the first direction E, and the second flow channel 202 includes a plurality of first through holes 202a penetrating the partition portion 200b along the first direction E.

[0064] In this embodiment, at least two grooves 200a are arranged on the mold core 200 at intervals along the first direction E. This layout helps to form uniformly distributed cooling channels inside the mold core 200. The second flow channel 202 is composed of a plurality of first through holes 202a, which penetrate the partition 200b along the first direction E, thereby connecting adjacent grooves 200a to form a continuous cooling path.

[0065] The design of the first through holes 202a allows the coolant to flow freely between the partitions 200b of the mold core 200, so that the temperature of each area can be effectively controlled during the molding process. In this way, the coolant can flow through each part of the mold core 200 more quickly, thereby improving the cooling efficiency and shortening the cooling time. At the same time, the uniform distribution of the first through holes 202a helps to evenly distribute the temperature over the entire surface of the mold core 200, which is crucial to preventing local overheating and maintaining the structural integrity of the molded part.

[0066] Continue reading Figure 3 In this embodiment, the groove 200a is a rectangular groove.

[0067] In this embodiment, the groove 200a is taken as a rectangular groove as an example, and the shape of the connection block 300 inserted into the groove 200a can also be set to be a rectangular protrusion. Of course, in other embodiments, it can also be an arc, triangle, etc.

[0068] In this embodiment, the rectangular groove is preferably used because it is easy to design and manufacture due to its simple geometric shape. They can be manufactured by a variety of processing methods, such as standard milling, CNC machining technology, and accurate manufacturing to ensure dimensional consistency and accuracy. Of course, it can also be manufactured by casting. These processes can achieve high-precision and high-quality grooves 200a, which are suitable for mass production.

[0069] In this embodiment, the regular shape of the groove 200a is designed as a rectangular groove, which helps to form a stable support structure inside the mold core 200, which can improve the stability and durability of the mold core 200 during the molding process. In addition, the right-angle edge of the rectangular groove helps the flow of the coolant, so that the coolant can cover the entire molding surface more evenly, thereby improving the cooling efficiency.

[0070] Continue reading Figures 4 to 6 In this embodiment, the first flow channel 108 includes a liquid inlet branch 110 and a liquid outlet branch 112. The liquid inlet branch 110 extends from the circumferential side wall 106 to the first plate surface 102 and is connected to the third flow channel 302 of one connecting block 300. The liquid outlet branch 112 extends from the circumferential side wall 106 to the first plate surface 102 and is connected to the third flow channel 302 of another connecting block 300.

[0071] In this embodiment, the design of the first flow channel 108 includes a liquid inlet branch 110 and a liquid outlet branch 112, which are responsible for introducing and discharging the coolant into and out of the mold respectively. Specifically, the liquid inlet branch 110 extends from the circumferential side wall 106 to the first plate surface 102 and is connected to a third flow channel 302 of a connecting block 300. Such a design ensures that the coolant can be directly transported from an external source to the inside of the mold, thereby starting its cooling cycle.

[0072] The liquid outlet branch 112 also extends from the circumferential side wall 106 to the first plate surface 102 and is connected to the third flow channel 302 of another connecting block 300. This ensures that the coolant can be discharged smoothly after absorbing heat inside the mold. In this way, by accurately designing the liquid inlet branch 110 and the liquid outlet branch 112, the coolant can quickly and effectively flow through each part of the mold to provide a uniform cooling effect.

[0073] Further, see Figure 4 and Figure 5 In this embodiment, the liquid inlet branch 110 includes a first hole segment 110a and a second hole segment 110b. The first hole segment 110a extends from the circumferential side wall 106 along the first direction E to the inside of the pad 100. The second hole segment 110b extends from the first hole segment 110a along the second direction F to the first plate surface 102 and communicates with a third flow channel 302 of a connecting block 300. The first direction E and the second direction F are arranged non-collinearly.

[0074] And / or, the liquid outlet branch 112 includes a third hole segment 112a and a fourth hole segment 112b, the third hole segment 112a extends along the second direction F to the first plate surface 102 and is connected to the third flow channel 302 of another connecting block 300, and the fourth hole segment 112b extends from the circumferential side wall 106 along the first direction E to the pad 100 and is connected to the third hole segment 112a.

[0075] In this embodiment, the design of the liquid inlet branch 110 and the liquid outlet branch 112 adopts a non-collinear setting, that is, the angles between the first hole segment 110a and the second hole segment 110b, and the third hole segment 112a and the fourth hole segment 112b are vertical or nearly vertical (90°±10°).

[0076] Specifically, the first hole segment 110a extends from the circumferential side wall 106 along the first direction E to the inside of the backing plate 100, while the second hole segment 110b extends from the first hole segment 110a along the vertical or approximately vertical second direction F to the first plate surface 102, and is communicated with the third flow channel 302 of one connecting block 300. The third hole segment 112a extends from the inside of the backing plate 100 to the first plate surface 102 along the second direction F, and is communicated with the third flow channel 302 of another connecting block 300, while the fourth hole segment 112b extends from the circumferential side wall 106 along the first direction E to the inside of the backing plate 100, and is communicated with the third hole segment 112a.

[0077] Furthermore, both ends of the first hole segment 110a and the second hole segment 110b pass through the pad. The reason for adopting such a design is, on the one hand, to facilitate the processing of the flow channel, and on the other hand, to connect the flow channel with the expanded mold insert; illustratively, two mold inserts can be set on the mold base at the same time, and the first hole segment 110a and the second hole segment 110b between the mold bases can be connected in series with pipes, so that it can avoid the need to separately connect a set of inlet and outlet pipes to a single mold insert.

[0078] If only one mold insert is installed, the first hole section 110a and the same end of the second hole section 110b can be blocked by a plug.

[0079] In this embodiment, the non-collinear arrangement allows the coolant to flow along a more complex path inside the mold, which helps to distribute the coolant more evenly, thereby improving cooling efficiency. By changing the direction of the hole segments, the internal space of the mold can be used more effectively and unnecessary material waste can be avoided.

[0080] Continue reading Figures 4 to 6 In this embodiment, the third flow channel 302 includes a flow slot 302a and a plurality of second through holes 302b, and the plurality of second through holes 302b are respectively connected to the second flow channel 202;

[0081] The flow groove 302a extends from one end of the connection block 300 close to the first plate surface 102 toward a direction away from the second plate surface 104, and is respectively connected to the first flow channel 108 and the plurality of second through holes 302b.

[0082] In this embodiment, the third flow channel 302 is designed to include a flow groove 302a and a plurality of second through holes 302b, and these second through holes 302b are respectively connected to the second flow channel 202, forming an efficient coolant flow system. Specifically, the flow groove 302a starts from one end of the connection block 300 close to the first plate surface 102 and extends in a direction away from the second plate surface 104. The design of the flow groove 302a enables the coolant to flow inside the connection block 300, thereby achieving the purpose of cooling.

[0083] The plurality of second through holes 302b are respectively connected to the circulation groove 302a, and each through hole is connected to the second flow channel 202. Such a design allows the coolant to enter each second through hole 302b from the circulation groove 302a and then flow into the second flow channel 202, thereby achieving effective distribution of the coolant inside the mold.

[0084] See also Figure 7 , Figure 7 It is a structural schematic diagram of a mold insert in one embodiment of the utility model.

[0085] In this embodiment, the first plate surface 102 is configured with an annular sealing groove 100 a , which is arranged around the periphery of the plurality of connection blocks 300 , and is used to place a sealing member.

[0086] In the present embodiment, only the construction of the annular sealing groove 100a on the first plate surface 102 is taken as an example. Of course, in some embodiments, on the basis of constructing the annular sealing groove 100a on the first plate surface 102, an annular protrusion is provided on the side of the mold core 200 facing the first plate surface 102; in this way, after the mold core 200 and the pad 100 are assembled, the annular protrusion extends into the annular sealing groove 100a to form a concave-convex structure. On the one hand, this design can achieve good sealing by placing a seal in the sealing groove to fill the gap between the annular protrusion and the annular sealing groove 100a. On the other hand, after the annular protrusion extends into the annular sealing groove 100a, the horizontal movement of the pad 100 relative to the mold core 200 can be limited, making it faster and more accurate during the assembly process.
