Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] In the description of the present invention, reference to terms such as "one embodiment" or "some embodiments" means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0036] The injection mold provided by the embodiment of the first aspect of the present invention includes an upper mold 100 and a lower mold 200, the upper mold 100 includes an upper mold frame 110 and an upper mold core assembly 120, the upper mold core assembly 120 is installed on the upper mold frame 110, the upper mold core assembly 120 includes an upper mold core 121 and a first connecting member 122, the first connecting member 122 is passed through the upper mold core 121 and is connected to the upper mold frame 110; the lower mold 200 includes a lower mold frame 210 and a lower mold core assembly 220, the lower mold core assembly 220 is installed on the lower mold frame 210, the lower mold core assembly 220 includes a lower mold core 221 and a second connecting member 222, the second connecting member 222 is passed through the lower mold core 221 and is connected to the lower mold frame 210; wherein, the upper mold 100 and the lower mold 200 are opposite to each other and can move relative to each other, and the upper mold core assembly 120 and the lower mold core assembly 220 can define a cavity.

[0037] For example, Figure 1 and Figure 2 As shown, the injection mold includes an upper mold 100 and a lower mold 200, and the upper mold 100 and the lower mold 200 are opposite and can move relative to each other. Figures 3 to 7 The upper mold core assembly 120 and the lower mold core assembly 220 can define a mold cavity. When the upper mold 100 and the lower mold 200 are relatively close to each other until the mold is closed, the raw material can be poured into the mold cavity and formed into an injection molded part after cooling. After the injection is completed, the upper mold 100 and the lower mold 200 are relatively separated until the mold is opened, and the injection molded part can be taken out. Figure 4 and Figure 5The upper mold core assembly 120 includes an upper mold core 121 and a first connecting member 122. The first connecting member 122 is provided through the upper mold core 121 and is connected to the upper mold frame 110. Figure 6 and Figure 7 The lower mold core assembly 220 includes a lower mold core 221 and a second connecting member 222 . The second connecting member 222 is passed through the lower mold core 221 and connected to the lower mold frame 210 . The first connecting piece 122 passes through the upper mold core 121 from one side of the mold cavity and connects the upper mold core 121 to the upper mold frame 110, and the second connecting piece 222 passes through the lower mold core 221 from one side of the mold cavity and connects the lower mold core 221 to the lower mold frame 210. When the upper mold core 121 or the lower mold core 221 needs to be disassembled and repaired, the upper mold core 121 or the lower mold core 221 can be disassembled separately on the injection molding machine. The upper mold core 121 or the lower mold core 221 can be repaired without removing the entire injection mold from the injection molding machine. During the repair process, the upper mold frame 110 and the lower mold frame 120 can be kept warm continuously. After the repair is completed, the injection mold can quickly restore the production temperature without waiting for the cooled injection mold to heat up as a whole. The upper mold core 121 and the lower mold core 221 can be quickly disassembled and assembled, which can effectively reduce the working hours consumed by maintenance and improve production efficiency.

[0038] It is understandable that, referring to Figure 2 A pouring gate 170 should be provided on the upper mold 100. The pouring gate 170 is connected to the mold cavity, and the raw material enters the mold cavity through the pouring gate 170 to produce the injection molded part. A guide pin sleeve 160 can be provided on the upper mold 100 and a guide pin 260 can be provided on the lower mold 200, or a guide pin 260 can be provided on the upper mold 100 and a guide pin sleeve 160 can be provided on the lower mold 200. The guide pin 260 can be inserted into the guide pin sleeve 160. The guide pin sleeve 160 and the guide pin 260 can play a positioning and guiding role during the mold closing and opening process, ensuring that the upper mold 100 and the lower mold 200 are accurately matched, and preventing the upper mold 100 and the lower mold 200 from shifting in position during the mold closing and opening process, which may affect the quality of the injection molded part. The number of upper mold cores 121 and lower mold cores 221 can be set according to demand. Multiple upper mold cores 121 and multiple lower mold cores 221 can be set to form multiple cavities. Runners are opened between the multiple cavities, so that multiple injection molded parts can be injected at the same time to improve production efficiency.

[0039] It should be noted that the upper mold core assembly 120 also includes an insert 223, which is arranged on the outside of the upper mold core 121, and the first connecting member 122 is passed through the insert 223 and connected to the upper mold frame 110, and / or the lower mold core assembly 220 also includes an insert 223, which is arranged on the outside of the lower mold core 221, and the second connecting member 222 is passed through the insert 223 and connected to the lower mold frame 221.

[0040] For example, Figures 4 to 7As shown, the upper mold core assembly 120 further includes an insert 223, which is disposed on the outer side of the upper mold core 121. The first connector 122 extends through the insert 223 and is connected to the upper mold frame 110. The lower mold core assembly 220 further includes an insert 223, which is disposed on the outer side of the lower mold core 221. The second connector 222 extends through the insert 223 and is connected to the lower mold frame 221. In the case of a complex cavity structure, the provision of the insert 223 can reduce the difficulty of injection mold processing and maintenance. In the case of a difficult-to-mold structure in the cavity, the provision of the insert 223 can facilitate venting during molding and prevent deformation of the molded part caused by vacuum during demolding.

[0041] It is understood that the insert 223 can be provided only on the upper mold 100, only on the lower mold 200, or on both the upper mold 100 and the lower mold 200. The mold cavity can be defined only by the upper mold core 121 and the lower mold core 221, or the upper mold core 121, the lower mold core 221, and the insert 223 can define the mold cavity together.

[0042] In some embodiments of the present invention, an air guide groove 2231 is provided on the surface of the insert 223 , and the air guide groove 2231 is communicated with the mold cavity.

[0043] For example, Figure 6 and Figure 7 As shown, the surface of the insert 223 is provided with an air guide groove 2231, which is connected to the mold cavity. The gas in the injection molding process can be discharged along the air guide groove 2231, which can reduce the injection pressure, injection time, holding time and clamping pressure, etc., reduce the molding difficulty of the injection molded parts, thereby reducing the loss of the machine, improving production efficiency and reducing production costs.

[0044] It is understandable that the shape and size of the air inlet groove 2231 can be set according to actual production requirements. Figure 8 Taking insert 223 in lower mold core assembly 220 as an example, air guide grooves 2231 are located on the surface of insert 223 near upper mold 100 and on the surface of insert 223 abutting lower mold core 221. This allows for quicker exhaust of gas within the mold cavity, resulting in better venting. The position of air guide grooves 2231 can also be adjusted based on actual production requirements.

[0045] In some embodiments of the present invention, the upper mold core assembly 120 is embedded in the upper mold frame 110, and the lower mold core assembly 220 is embedded in the lower mold frame 210. A first processing groove 111 is opened at the side of the upper mold frame 110, and the upper mold core assembly 120 can be exposed from the first processing groove 111. A second processing groove 211 is opened at the side of the lower mold frame 210, and the lower mold core assembly 220 can be exposed from the second processing groove 211.

[0046] For example, Figures 4 to 7 As shown, the upper mold core assembly 120 is embedded in the upper mold frame 110, and the lower mold core assembly 220 is embedded in the lower mold frame 210. The upper mold frame 110 can protect the upper mold core assembly 120, and the lower mold frame 210 can protect the lower mold core assembly 220. Figures 4 and 5 As shown, the first processing groove 111 is opened at the side of the upper mold frame 110, and a notch is formed on the side of the upper mold frame 110, and the upper mold core assembly 120 can be exposed from the first processing groove 111; Figures 6 and 7 As shown, the second processing groove 211 is opened on the side of the lower mold frame 210, and a notch is formed on the side of the lower mold frame 210, so that the lower mold core assembly 220 can be exposed from the second processing groove 211. Opening the first processing groove 111 on the side of the upper mold frame 110 and the second processing groove 211 on the side of the lower mold frame 210 can reserve processing space for the grinder. Using the grinder to process the upper mold frame 110 and the lower mold frame 210 can provide high processing precision, which can improve the dimensional accuracy of the injection mold, thereby producing better quality injection molded parts.

[0047] In some embodiments of the present invention, the upper mold 100 includes a cooling portion 130, in which a gate cooling water channel 131 is opened. The upper mold 100 also includes a gate sleeve 140, which is embedded in the cooling portion 130. A cooling groove 141 is provided on the outer periphery of the gate sleeve 140, and the cooling groove 141 is connected to the gate cooling water channel 131.

[0048] For example, Figure 9 As shown, the upper mold 100 includes a cooling portion 130, within which a gate cooling water channel 131 is defined. A sprue bushing 140 is embedded within the cooling portion 130. A cooling groove 141 is disposed on the periphery of the sprue bushing 140, which communicates with the gate cooling water channel 131. During the injection molding process, water flows through the cooling groove 141 to cool the sprue bushing 140, thereby cooling the raw material passing through the sprue bushing 140. This can shorten the injection molding cycle and improve production efficiency.

[0049] It is understood that the cooling portion 130 is a part of the upper mold 100, such as Figure 9 As shown, the cooling part 130 is a part of the insert 223 in the middle of the upper mold 100, and the gate cooling water channel 131 is opened in the insert 223. According to different structures of the upper mold core assembly 120, the position of the cooling part 130 is not limited to Figure 9 The position shown can also be a portion of the upper mold core 121, or a combination of a portion of the upper mold core 121 and a portion of the insert 223. A channel for the raw material to flow should be provided within the sprue bushing 140. The channel is connected to the pouring gate 170 and the mold cavity. The raw material is injected from the pouring gate 170 and flows into the mold cavity through the channel within the sprue bushing 140.

[0050] In some embodiments of the present invention, a sealing groove is further provided on the outer periphery of the sprue sleeve 140 , which is located at both ends of the cooling groove 141 . A sealing ring 142 is provided in the sealing groove, and the sealing ring 142 is clamped between the sprue sleeve 140 and the cooling part 130 .

[0051] For example, Figure 9 As shown, the outer periphery of the sprue bushing 140 is further provided with sealing grooves located at both ends of the cooling groove 141. Sealing rings 142 are provided in the sealing grooves and are clamped between the sprue bushing 140 and the cooling portion 130. The provision of the sealing grooves and sealing rings 142 can prevent water from leaking into the mold cavity or the pouring gate 170 during the water cooling process.

[0052] In some embodiments of the present invention, the upper mold 100 further includes an upper mold core cooling water channel 150 , and / or the lower mold 200 further includes a lower mold core cooling water channel 230 .

[0053] For example, Figure 2 and Figure 3 As shown, an upper core cooling water channel 150 is provided inside the upper mold 100, and a lower core cooling water channel 230 is provided inside the lower mold 200. The upper core cooling water channel 150 cools the cavity on the upper mold 100 side, while the lower core cooling water channel 230 cools the cavity on the lower mold 200 side, shortening the molding cycle and improving production efficiency.

[0054] It is understandable that the upper mold core cooling water channel 150 can be provided only inside the upper mold 100, or the lower mold core cooling water channel 230 can be provided only inside the lower mold 200, as long as the molding requirements of the injection molded parts are met. Figure 3 The upper mold core cooling water channel 150 and the lower mold core cooling water channel 230 should be set at the corresponding positions of the cavity. A plurality of staggered water pipes can be set to form the upper mold core cooling water channel 150 and the lower mold core cooling water channel 230 to ensure the cooling effect.

[0055] In some embodiments of the present invention, the lower mold 200 also includes an ejector rod 240, part of which is accommodated inside the lower mold frame 210. The ejector rod 240 can move toward or away from the upper mold 100 so that part of the ejector rod 240 extends out or retracts into the lower mold frame 210.

[0056] For example, Figure 10As shown, a portion of the ejector pin 240 is housed within the lower mold frame 210. The ejector pin 240 can move toward or away from the upper mold 100. After injection molding is completed, the upper mold 100 and lower mold 200 open, and the ejector pin 240 moves toward the upper mold 100 to eject the molded part from the cavity. After ejection, the ejector pin 240 moves away from the upper mold 100 to continue the next injection molding cycle.

[0057] In some embodiments of the present invention, the lower mold 200 also includes an ejector reset assembly 250, which is arranged inside the lower mold frame 210. The ejector reset assembly 250 includes a base 251, an ejector plate 252 and a reset spring 253. The reset spring 253 is located between the base 251 and the ejector plate 252. The base 251 is clamped to the inside of the lower mold frame 210. One end of the ejector rod 240 is connected to the ejector plate 252. The ejector plate 252 can move within the lower mold frame 210 to make the ejector rod 240 closer to or farther away from the upper mold 100.

[0058] For example, Figure 10 As shown, the return spring 253 is located between the base 251 and the ejector plate 252. The base 251 is clamped to the interior of the lower mold frame 210. One end of the ejector rod 240 is connected to the ejector plate 252. The ejector plate 252 can move within the lower mold frame 210 to move the ejector rod 240 closer to or further away from the upper mold 100. After the injection molding is completed, the upper mold 100 and the lower mold 200 are opened. The ejector plate 252 is pushed to move the ejector rod 240 toward the upper mold 100. The return spring 253 is compressed, ejecting the molded part from the mold cavity. After the ejection, the external force is removed, and the return spring 253 pushes the ejector plate 252 to move the ejector rod 240 away from the upper mold 100, retracting it into the lower mold 200, and continuing the next injection molding. The ejection reset assembly 250 can restore the ejection rod 240 to its original position after each ejection, thereby preventing the ejection rod 240 from failing to restore to its original position, thereby affecting the clamping of the upper mold 100 and the lower mold 200 and affecting product quality.

[0059] The second embodiment of the present invention provides an injection mold system, including a disassembly fixture 300 and an injection mold of any of the above embodiments, wherein the disassembly fixture 300 includes a fixing plate 310 and a third connecting member, wherein the fixing plate 310 includes a core protection portion 311 and a fixing portion 312, wherein the fixing portion 312 is located on the periphery of the core protection portion 311, and the fixing portion 312 is provided with a plurality of fixing holes 3121, and the disassembly fixture 300 can be moved closer to or farther from the upper mold frame 110, and the disassembly fixture 300 is used to be fixed to the upper mold core assembly 120. The upper mold core assembly 120 can be removed or installed, the core protection part 311 can cover the upper mold core 121, the third connecting part is passed through the fixing hole 3121 and is connected to the upper mold core assembly 120, or the disassembly and assembly fixture 300 can be close to or away from the lower mold frame 210, the disassembly and assembly fixture 300 is used to be fixed on the lower mold core assembly 220 to remove or install the lower mold core assembly 220, the core protection part 311 can cover the lower mold core 221, and the third connecting part is passed through the fixing hole 3121 and is connected to the lower mold core assembly 220.

[0060] For example, Figure 11 As shown, the fixing plate 310 includes a core protection portion 311 and a fixing portion 312. The fixing portion 312 is located on the periphery of the core protection portion 311. The fixing portion 312 is provided with a plurality of fixing holes 3121. Figure 5 When the upper mold core assembly 120 needs to be disassembled, the first connecting piece 122 on the upper mold core assembly 120 can be removed first, and then the core protection part 311 of the fixing plate 310 can be covered on the cavity part of the upper mold core 121, and the fixing part 312 can be covered on the outer periphery of the upper mold core 121. The outer periphery of the upper mold core 121 is used to fix the upper mold core 121, and then the third connecting piece is passed through the fixing hole 3121 and connected to the mounting hole of the upper mold core 121. The mounting hole is used to pass the first connecting piece 122, so that the fixing plate 310 and the upper mold core 121 are fixed together. The upper mold core 121 can be taken out by pulling the fixing plate 310. Because the first connector 122 attaches the upper mold core 121 to the upper mold frame 110 from the cavity side, the cavity portion of the upper mold core 121 may be damaged or worn during assembly and disassembly. The upper mold core assembly 120 is disassembled using a disassembly fixture 300. The fixed plate 310 covers the upper mold core 121, preventing damage and wear to the upper mold core 121 during assembly and disassembly. This prevents the disassembly process from affecting the dimensional accuracy of the upper mold core 121 and ensures the quality of the injection molded part. It should be noted that if the upper mold core assembly 120 includes an insert 223, the insert 223 and the upper mold core 121 can be fixed to the fixed plate 310 simultaneously and removed simultaneously. If the lower mold core assembly 220 needs to be disassembled, the same method as described above can be used.

[0061] It is understood that a handle can be provided on the fixing plate 310. After the fixing plate 310 is secured to the upper core assembly 120 or the lower core assembly 220, the handle can be pulled to remove the upper core assembly 120 or the lower core assembly 220. The fixing holes 3121 should be provided at positions corresponding to the mounting holes of the first connecting member 122 of the upper core assembly 120 and / or the mounting holes of the second connecting member 222 of the lower core assembly 220. Providing fixing holes 3121 at positions corresponding to the mounting holes of the first connecting member 122 of the upper core assembly 120 and the second connecting member 222 of the lower core assembly 220 on the fixing portion 312 allows the disassembly fixture 300 to be used for both the upper and lower core assemblies 120 and 220, respectively. This allows for the disassembly of the upper and lower core assemblies 120 and 220 to be completed using only one disassembly fixture 300, thereby reducing manufacturing costs.

[0062] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
