In the related art, the injection molding device is relatively large, and the injection molding device includes an injection molding table and an injection molding mold. The plastic mold is fixed to the injection molding table by screws, and there is a problem of inconvenient transportation of the injection molding mold, and the flexibility is low. When the operator performs the cable injection molding, it is necessary to approach the injection molding table and manually place the cable in the injection molding mold for injection molding. If the operator accidentally touches the start button, it is easy to be pressed on the hand or burned, and the safety is low. Usually, in order to improve the injection molding efficiency, multiple cables are often injection molded at the same time; however, the cable wire is small and relatively soft, and the injection molding glue flows in the injection molding space and the injection molding glue has a certain pressure, which will cause the injection molding glue to distort the cable wire, resulting in the cable bursting, resulting in the injection molding glue skin being unable to completely and evenly wrap the cable, with a high scrap rate. In addition, if the impact of the injection rubber is too great when it flows in the injection space, it is easy to cause excessive injection rubber in the injection cavity and cause overflow. The overflowing injection rubber flows in the injection cavity and easily sticks different cables together, making it impossible to produce qualified charging cables, resulting in a high scrap rate.

[0028] The charging cable is a type of data cable and is a necessary structure for charging electronic devices. The charging cable is formed by injection molding the cable. In the related art, the injection molding device is relatively large, and the injection molding device includes an injection molding table and an injection molding mold. The plastic mold is fixed to the injection molding table by screws, and there is a problem of inconvenient transportation of the injection molding mold, and the flexibility is low. When the operator performs the cable injection molding, it is necessary to approach the injection molding table and manually place the cable in the injection molding mold for injection molding. If the operator accidentally touches the start button, it is easy to be pressed on the hand or burned, and the safety is low. Usually, in order to improve the injection molding efficiency, multiple cables are often injection molded at the same time; however, the cable wire is small and relatively soft, and the injection molding glue flows in the injection molding space and the injection molding glue has a certain pressure, which will cause the injection molding glue to distort the cable wire, resulting in the cable bursting, resulting in the injection molding glue skin being unable to completely and evenly wrap the cable, with a high scrap rate. In addition, if the impact of the injection rubber is too great when it flows in the injection space, it is easy to cause excessive injection rubber in the injection cavity and cause overflow. The overflowing injection rubber flows in the injection cavity and easily sticks different cables together, making it impossible to produce qualified charging cables, resulting in a high scrap rate.
[0029] Based on this, an embodiment of the present application provides a cable injection mold, which can make the injection rubber flow in a preset direction through a guiding and positioning module, effectively avoiding the problem of injection rubber overflow and improving the yield rate of injection molded products.
[0030] Please refer to the accompanying drawings to further explain this application.
[0031] Reference Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structural decomposition of a cable injection mold provided in an embodiment of the present application, Figure 2 It is a structural schematic diagram of a lower mold 200 provided in an embodiment of the present application; the cable injection mold includes a clamping unit and a guiding and positioning module, the clamping unit includes an upper mold 100 and a lower mold 200, and an injection cavity 210 for placing the cable is formed after the upper mold 100 and the lower mold 200 are clamped, and the lower mold 200 is provided with a pouring channel 220, and the pouring channel 220 is connected to the injection cavity 210; the guiding and positioning module includes a cross bar 310 and an isolation unit 320, the upper mold 100 is provided with a first card slot 110, and the lower mold 200 is provided with a second card slot 230, when the upper mold 100 and the lower mold 200 are clamped, a receiving groove is formed between the first card slot 110 and the second card slot 230; the cross bar 310 is used to be placed in the receiving groove, and the isolation unit 320 is used to be placed in the injection cavity 210, so that the injection molded rubber flows in the injection cavity 210 according to a preset direction.
[0032] After the upper mold 100 and the lower mold 200 are molded together, an injection cavity 210 is formed. The injection cavity 210 is used to place the cable to be injected. When the upper mold 100 and the lower mold 200 are molded together, a receiving groove is formed between the first slot 110 of the upper mold 100 and the second slot 230 of the lower mold 200, the cross bar 310 is placed in the receiving groove, and the isolation unit 320 is placed in the injection cavity 210; the pouring channel 220 is connected to the injection cavity 210. When the cable to be injected is subjected to injection molding, the injection molding rubber flows into the injection cavity 210 through the pouring channel 220 to wrap the cable to be injected. The isolation unit 320 placed in the injection cavity 210 can ensure that the injection molding rubber flows in the injection cavity 210 in a preset direction, blocks the misaligned flow of the injection molding rubber, and can effectively avoid the problem of overflow of the injection molding rubber, thereby improving the molding effect of the product and thus improving the yield rate of the injection molded product.
[0033] In some embodiments of the present application, the depth of the first card slot 110 and the second card slot 230 are both half the width of the crossbar 310. By setting the depth of the first card slot 110 and the second card slot 230 to be half the width of the crossbar 310, when the upper mold 100 and the lower mold 200 are molded together, the accommodating groove formed between the first card slot 110 and the second card slot 230 can stably wrap the crossbar 310, so that the crossbar 310 provides a fixed force for the guide positioning module, avoiding the problem of displacement of the guide positioning module caused by the impact force of the injection molding rubber.
[0034] In some embodiments of the present application, the upper mold 100 and the lower mold 200 are made of steel materials that meet the requirements of thermal deformation strength. The steel materials with thermal deformation strength meet the requirements of product injection molding and can ensure that the upper mold 100 and the lower mold 200 will not be deformed due to the high-temperature injection molding rubber flowing in the injection cavity 210. Steel materials that meet the requirements of thermal deformation strength include one of microalloyed C-Mn-Al high-strength steel, S280 ultra-high-strength stainless steel, 304 stainless steel, and boron steel for hot stamping. The embodiments of the present application do not limit the materials of the upper mold 100 and the lower mold 200.
[0035] In the conventional technology, the injection molding device includes an injection molding table and an injection molding mold. The molding mold is fixed on the injection molding table by screws, which causes the problem of inconvenient transportation of the injection molding mold and low flexibility. When the operator performs cable injection molding, he needs to approach the injection molding table and manually place the cable in the injection molding mold for injection molding, which poses certain safety hazards. Different from the conventional technology, the cable injection molding mold in the embodiment of the present application is fixed on the injection molding table by a pressing sheet fixing clamp, and the cable injection molding mold can be disassembled and installed at any time, which increases the flexibility of the cable injection molding mold; in addition, when the injection molding process needs to be performed, the cable injection molding mold can be first removed from the injection molding table, and then the cable to be injected is placed in the injection molding cavity 210, and then the cable injection molding mold is fixed back to the injection molding table by the pressing sheet fixing clamp, and the switch button is started for injection molding. In the present application, the cable injection molding mold is fixed on the injection molding table by a pressing sheet fixing clamp, so that the operator does not need to approach the injection molding table to manually place the cable in the injection molding mold for injection molding, which improves the safety of the injection molding process.
[0036] In some embodiments of the present application, the injection cavity 210 includes a first cavity 211 , a second cavity 212 , and a third cavity 213 , and the third cavity 213 is disposed between the first cavity 211 and the second cavity 212 .
[0037] The injection molding cavity 210 includes three cavities, the first cavity 211 is used to place the first cable to be injection molded, the second cavity 212 is used to place the second cable to be injection molded, when performing the injection molding process, the injection molding material flows in the first cavity 211, so that the injection molding material is injection-molded and wrapped around the first cable to be injection molded, and the injection molding material flows in the second cavity 212, so that the injection molding material is injection-molded and wrapped around the second cable to be injection molded, and the third cavity 213 is arranged between the first cavity 211 and the second cavity 212, and the third cavity 213 is arranged between the first cavity 211 and the second cavity 212. 13 is provided with an isolation unit 320, which can ensure that the injection rubber flows in a preset direction in the injection cavity 210, effectively preventing the injection rubber from flowing from the first cavity 211 to the second cavity 212 or the injection rubber from the second cavity 212 to the first cavity 211. The isolation unit 320 prevents the injection rubber from flowing out of position, and can effectively prevent the injection rubber from overflowing, thereby reducing the probability of product cracking, improving the molding effect of the product, and thus improving the yield rate of the injection molded product.
[0038] In some embodiments of the present application, the pouring channel 220 includes a pouring port 221, a first pipe 222 and a second pipe 223, one end of the first pipe 222 is connected to the pouring port 221, the other end of the first pipe 222 is connected to the second pipe 223, one end of the second pipe 223 is connected to the first cavity 211, and the other end of the second pipe 223 is connected to the second cavity 212.
[0039] The pouring port 221 is connected to one end of the first pipe 222, and the other end of the first pipe 222 is connected to the second pipe 223, so that after the injection molding material flows into the pouring port 221, the injection molding material flows in the first pipe 222, and flows to the second pipe 223 through the first pipe 222, one end of the second pipe 223 is connected to the first cavity 211, and the other end of the second pipe 223 is connected to the second cavity 212, so that a part of the injection molding material flowing in the second pipe 223 flows to the first cavity 211 to injection mold the first cable to be injected placed in the first cavity 211, and the other part flows to the second cavity 212 to injection mold the second cable to be injected placed in the second cavity 212. By setting one end of the first pipe 222 to be connected to the pouring port 221, the high-temperature and high-pressure injection molding material flowing into the pouring port 221 can be buffered in the first pipe 222, and evenly flow to the second pipe 223 before being diverted to the first cavity 211 and the second cavity 212, thereby avoiding the pouring port 221 being directly connected to the first cavity 211 and the second cavity 212, so that the impact force of the injection molding material is too great, causing the cables to be injected to be distorted and burst out. At the same time, it can also avoid the problem that the impact force of the injection molding material is too great, causing the injection molding material to overflow and bond different cables together, resulting in an excessively high scrap rate.
[0040] Reference Figure 3, Figure 3 It is a structural schematic diagram of a guiding and positioning module provided in an embodiment of the present application. In some embodiments of the present application, the guiding and positioning module includes a cross bar 310 and an isolation unit 320. The isolation unit 320 includes a card block 321 and a blocking member 322. The card block 321 is provided with a through hole. The size of the through hole matches the size of the blocking member 322, and the blocking member 322 passes through the through hole.
[0041] The isolation unit 320 includes a card block 321, which is provided with a through hole and the size of the through hole matches the size of the blocking piece 322. The blocking piece 322 is inserted into the through hole and fixed on the card block 321, and the card block 321 with the blocking piece 322 is placed in the third cavity 213. The card block 321 with the blocking piece 322 allows the injection molding material to flow in a preset direction, effectively preventing the injection molding material from flowing from the first cavity 211 to the second cavity 212 or the injection molding material from flowing from the second cavity 212 to the first cavity 211. The card block 321 with the blocking piece 322 plays a role in preventing the injection molding material from misaligned flow, and preventing the injection molding material from bonding the first cable to be injected in the first cavity 211 and the second cable to be injected in the second cavity 212 together, resulting in a high scrap rate.
[0042] It should be noted that in some embodiments of the present application, the third cavity 213 includes a first groove and a second groove, the first groove matches the size of the block 321 , and the second groove matches the size of the blocking member 322 . One end of the first groove is connected to the second groove 230 .
[0043] By setting the third cavity 213 to include a first groove and a second groove, the sizes of the first groove and the block 321 match, and the sizes of the second groove and the blocking piece 322 match, and one end of the first groove is connected to the second groove 230, so that the block 321 with the blocking piece 322 can be placed in the third cavity 213 through the first groove and the second groove, and the block 321 with the blocking piece 322 allows the injection molding material to flow in a preset direction, effectively preventing the injection molding material from flowing from the first cavity 211 to the second cavity 212 or the injection molding material from flowing from the second cavity 212 to the first cavity 211, and the block 321 with the blocking piece 322 plays a role in preventing the injection molding material from flowing out of place.
[0044] Reference Figures 1 to 4 In some embodiments of the present application, a protruding buckle 330 is provided on the inner side of the lower mold 200, and an opening 120 corresponding to the protruding buckle 330 is provided on the upper mold 100. The protruding buckle 330 and the opening 120 cooperate to lock the mold unit.
[0045] By providing a protruding buckle 330 on the lower mold 200 and an opening 120 corresponding to the protruding buckle 330 on the upper mold 100, when the upper mold 100 and the lower mold 200 are closed, the protruding buckle 330 and the opening 120 cooperate to lock the closing unit, thereby ensuring that the injection molding process proceeds normally, avoiding overflow or misaligned flow of the injection molding material during the injection molding process, improving the molding effect of the product, and thus improving the yield rate of the injection molded product.
[0046] In some embodiments of the present application, the cable injection mold further includes a baffle and a wire trough 130, the wire trough 130 is used to place the cable, and the baffle is used to block the injection molding rubber from flowing down to the wire trough 130. By setting the baffle, the injection molding rubber can be effectively blocked from flowing down to the wire trough 130, and the injection molding rubber is prevented from flowing down to the wire trough 130, causing the cable part in the wire trough 130 that does not need to be injected to be disturbed by the injection molding rubber, thereby affecting the appearance of the cable that does not need to be injected. The cable injection mold further includes a support plate 140, and the support plate 140 is used to support the cable placed in the wire trough 130. The support plate 140 can play a role in fixing the cable, and the support plate 140 supports the cable to prevent the cable from hanging down, thereby avoiding the displacement of the part of the cable that needs to be injected. The accuracy of the injection molding process is improved.
