[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The height position of the synchronous bracket can be adjusted by the hydraulic cylinder, and the upper mold can be driven to apply downward pressure to realize subsequent injection molding operations. An upper mold and two lower molds are designed through this application. Compared with the existing injection molds, this application can realize separate molding and material removal operations by alternating the two lower molds, effectively improving the efficiency of continuous injection molding. By alternating the two lower molds continuously by alternating the components, the number of molds used can be reduced on the basis of efficient molding.

[0018] 2. The buffer spring can be used to buffer the contact between the base and the lower mold to avoid collision. Part of the material can be stored in advance through the receiving groove, and after the receiving groove is filled, the material is fed into the molding groove through the feed hole. The above structure can improve the molding quality of the product, and when the upper mold moves up after the molding is completed, the support spring is used to push the current push plate downward. In this process, the waste material will be separated from the product and the remaining material at the sprue to avoid residue affecting the subsequent molding process.

[0019] 3. By moving the synchronous bracket upward, the first connecting rod is used to pull the slide plate upward, thereby moving the sealing piston at the upper end of the synchronous rod upward and reducing the air inside the air storage cavity. During this operation, the cavity will enter the air nozzle along with the connecting hose and be ejected. The air nozzle is located at a height between the base and the push plate. After the molding is completed, the waste material can be discharged from the mold when it moves upward. The guide baffle can make the waste material fall to a specified range for the operator to remove. The above structure can further optimize the material removal efficiency while meeting the high-quality molding requirements of the application and avoid interfering with the overall processing efficiency. Similarly, during the downward pressure molding process, when the sealing piston moves downward, the air nozzle will replenish the outside air into the air storage cavity to facilitate the next auxiliary jet.

[0020] 4. When the driving column rotates, the gear column engages with the matching gear, causing the multiple rotating seats to rotate. The limit block and the matching slide groove are used to limit the position, and the screw hole and the screw thread cooperate to achieve the adjustment of the screw height up and down, and the limit seat and the limit slot are limited. After the alternation is completed, the application performs an auxiliary self-locking operation to avoid the occurrence of the placement turntable movement during the subsequent injection molding process, thereby improving the stability of the application during the injection molding process;

[0021] The specific thread pitch and the number of gear transmission circles are adjusted according to the actual equipment size, and the driving column rotates a quarter of a turn from bottom to top or from top to bottom to match the alternating frequency of the turntable. The three-phase asynchronous motor can be used for forward and reverse rotation drive to enable the screw to move up and down. During the demoulding process, the lower mold to be demoulded is approached to the limit card seat. Under the push of the limit card seat, the first spring contracts and controls the baffle to move up, so that the series hole opens the connecting channel and under the subsequent air supply, drives the movable top column to move upward to realize automatic assisted demoulding.

The height position of the synchronous bracket 2 can be adjusted by the hydraulic cylinder 102, and the upper mold 7 can be driven to apply downward pressure to realize subsequent injection molding operations. An upper mold 7 and two lower molds 6 are designed through this application. Compared with the existing injection molds, this application can effectively improve the efficiency of continuous injection molding by alternating the two lower molds 6 to realize separate molding and material removal operations. By alternating the two lower molds 6 continuously through the alternating component 5, the number of molds used can be reduced on the basis of efficient molding.

[0042] In this embodiment, a storage box 8 and a warehouse door 9 are respectively provided on both sides of the workbench 1. The upper end of the storage box 8 is respectively connected to a heater and an auger conveyor 801. A material delivery hose 802 is installed at the discharge point of the auger conveyor 801. The workbench 1 is provided with a placement groove 901 at the warehouse door 9. A three-phase asynchronous motor 902 for driving is installed inside the placement groove 901, and a driving gear 903 is fixedly installed at the output end of the three-phase asynchronous motor 902.

[0043] By starting the auger conveyor 801, the injection molding material stored in the storage box 8 can be transported, wherein the heater is used to heat and melt the injection molding material, and then the auger conveyor 801 is used to discharge the material from the delivery hose 802 to realize automatic feeding operation; by starting the three-phase asynchronous motor 902, the driving gear 903 can be rotated, wherein the driven gear 5012 is engaged with the driving gear 903 to realize the alternating operation of the alternating component 5 to drive the alternating operation to meet the alternating requirements of the two lower molds 6.

[0045] The movable top column 603 is movably arranged inside the through-hole 601, so that after the injection molding is completed, the movable top column 603 can be moved upward to discharge the product located outside the molding protrusion 602, which is beneficial for the operator to quickly remove the product, and the alternating processing further improves the processing efficiency.

[0046] In this embodiment, the upper mold 7 includes a base 701, which is fixed inside the synchronous bracket 2. The lower end of the base 701 is connected to a push plate 704 and a base 705 through a connecting rod 703. A molding groove 7053 is provided at the bottom of the base 705. A support spring 7041 is installed between the push plate 704 and the base 701. A connecting groove 7052 is provided inside the base 705. A buffer spring 7051 is provided between the connecting groove 7052 and the connecting rod 703. A receiving groove 7054 is provided at the top of the base 705. A feed hole 7055 is provided between the receiving groove 7054 and the molding groove 7053. A feed pipe 702 is provided at the upper end of the base 701, and the feed pipe 702 is connected to the delivery hose 802.

[0047] Through the buffer spring 7051, the base 705 can be buffered when it contacts the lower mold 6 to avoid collision, wherein part of the material can be pre-stored through the receiving groove 7054, and after the receiving groove 7054 is filled, the material is fed into the molding groove 7053 through the feed hole 7055. The above structure can improve the molding quality of the product, and when the upper mold 7 moves upward after the molding is completed, the support spring 7041 is used to push the current push plate 704 downward. In this process, the waste material will be separated from the product and the remaining material at the sprue to avoid residue affecting the subsequent molding process.

[0048] In this application, the auxiliary component 4 includes a support 401, which is fixedly installed above the boss 3. An air storage cavity 402 is provided on the upper side of the support 401. An air nozzle 405 is fixedly installed on the lower side of the synchronization bracket 2. The upper end of the air storage cavity 402 is connected to the air nozzle 405 through a connecting hose 404. A guide baffle 201 is fixedly installed on one side of the synchronization bracket 2.

[0049] Among them, a first connecting rod 202 is fixedly installed on one side of the synchronization bracket 2, a synchronization rod 403 is movably arranged inside the air storage cavity 402, a sealing piston 4031 is installed on the upper end of the synchronization rod 403, and a sliding plate 4032 is installed on the lower end of the synchronization rod 403, and the sliding plate 4032 is fixedly connected to the first connecting rod 202.

[0050] By moving the synchronous bracket 2 upward, the first connecting rod 202 is used to pull the sliding plate 4032 upward, thereby causing the sealing piston 4031 at the upper end of the synchronous rod 403 to move upward and reduce the air inside the air storage cavity 402. Under this operation, the cavity will enter the air nozzle 405 along with the connecting hose 404 and be ejected.

The guide baffle 201 can be used to make the waste material fall to a specified range for the operator to take out. The above structure can further optimize the material collection efficiency while meeting high-quality molding requirements and avoid interfering with the overall processing efficiency. Similarly, during the downward pressure molding process, when the sealing piston 4031 moves downward, the air nozzle 405 will replenish the outside air into the air storage cavity 402 to facilitate the next auxiliary jet.

[0051] In this application, a mating gear 5011 is provided in the middle of the driving column 501, and a driven gear 5012 is provided at the lower end of the driving column 501. One side of the bottom of the rotating groove 103 is interconnected with the placement groove 901, and the driven gear 5012 is meshed with the driving gear 903. The meshing of the driven gear 5012 and the driving gear 903 allows the driving column 501 to rotate under the drive of the three-phase asynchronous motor 902, thereby driving the placement turntable 502 and the two lower molds 6 above it to swap positions to meet the alternating needs.

[0052] It should be noted that a number of limiting slots 503 are provided on the outer side of the middle part of the rotating slot 103, and a gear column 5032 is rotatably installed at the bottom of the limiting slot 503, which meshes with the matching gear 5011, and a rotating seat 5031 is fixedly installed on the upper end of the gear column 5032.

A limiting clamping seat 5036 is fixedly installed on the upper end of the screw 5035, and a number of limiting clamping slots 5026 are provided on the bottom of the rotating disk 502, and the limiting clamping seat 5036 is limited and matched with the limiting clamping slot 5026.

[0053] When the driving column 501 rotates, the tooth column 5032 meshes with the matching gear 5011, causing the multiple rotating seats 5031 to rotate. The limiting block 5034 and the matching slide groove 5037 are used for limiting cooperation, and the screw hole 5033 and the screw rod 5035 are threadedly engaged, thereby achieving the upper and lower height adjustment of the screw rod 5035, and achieving the limiting cooperation between the limiting seat 5036 and the limiting groove 5026. After the alternation is completed, the present invention performs an auxiliary self-locking operation, avoiding the situation where the placement turntable 502 moves during the subsequent injection molding process, thereby improving the stability of the present invention during the injection molding process;

[0054] The specific thread pitch and number of gear transmission circles are adjusted according to the actual equipment size, and the screw 5035 drives the column 501 to rotate a quarter of a turn from bottom to top or from top to bottom to match the alternating frequency of the turntable 502. The three-phase asynchronous motor 902 can be used for forward and reverse rotation drive to enable the screw 5035 to move up and down in height.

[0055] During the specific setting, connecting channels 5021 are respectively provided on both sides of the interior of the turntable 502, and a docking rod 5027 is fixedly installed on the upper end of the connecting channel 5021, and the docking rod 5027 is connected to the through-hole 601. A series groove 5022 is opened in the middle of the connecting channel 5021, and a control baffle 5023 is movably installed inside the series groove 5022 through a first spring 5024, and a series hole 5025 is opened on the lower side of the control baffle 5023.

[0056] During the demoulding process, the lower mold 6 to be demoulded is brought close to the limiting holder 5036. Under the push of the limiting holder 5036, the first spring 5024 contracts and controls the baffle 5023 to move upward, so that the serial hole 5025 opens the connecting channel 5021 and under the subsequent air supply, drives the movable top column 603 to move upward, thereby realizing automatic assisted demoulding.

[0057] Among them, an air supply channel 504 is opened on one side of the workbench 1, one end of the air supply channel 504 is interconnected with the adjacent connecting channel 5021, and an air storage rod 505 is installed on the other end of the air supply channel 504. A piston rod 5051 is movably provided inside the air storage rod 505, and an air supply hole 5052 is opened on the upper side of the air storage rod 505. A second connecting rod 203 is fixedly installed on one side of the synchronous bracket 2, and the second connecting rod 203 is connected to the upper end of the piston rod 5051. An expansion slot 5041 is opened at one end of the air supply channel 504, and a docking cover 5042 is movably installed in the expansion slot 5041 through a second spring 5043.

[0058] When the lower mold 6 at one end is completed and moved out and the lower mold 6 at the other end is in the process of being pressed downward to form, the lower mold 6 that has completed the processing can be assisted in demolding. During the downward movement of the synchronous bracket 2, the piston rod 5051 is driven to press down to realize the exhaust of the air storage rod 505 to the air supply channel 504. During the exhaust process, the gas will enter the air supply channel 504 and then enter the adjacent connecting channel 5021 to meet the power required for demolding. The docking cover 5042 is movably installed on the expansion slot 5041 through the second spring 5043 to ensure stable air supply operation between the air supply channel 504 and the connecting channel 5021.

[0059] The working principle of an alternating injection mold for automobile parts production:

[0060] When in use, first install the upper mold 7 into the synchronous bracket 2 as needed, and the two lower molds 6 are respectively installed at both ends of the upper surface of the placement turntable 502, thereby completing the preparation work;

[0061] Then, the synchronous support 2 is lowered by starting the hydraulic cylinder 102, and the upper mold 7 is pressed against one of the lower molds 6. Then, the auger conveyor 801 is started to convey the injection molding material stored in the storage box 8. The heater is used to heat and melt the injection molding material, and then the auger conveyor 801 is used to discharge the material from the feeding hose 802 to realize automatic feeding operation, so that the material enters between the upper mold 7 and the current lower mold 6 for injection molding.

[0062] After the molding is completed, the hydraulic cylinder 102 is started to make the synchronous bracket 2 rise and reset. After the upper mold 7 and the current lower mold 6 are separated, the three-phase asynchronous motor 902 is started to rotate the driving gear 903, wherein the driven gear 5012 is engaged with the driving gear 903, so that the placement turntable 502 rotates half a circle to complete the alternating operation, so that the other lower mold 6 is located below the upper mold 7 to facilitate the next molding. After the next round of molding is completed, the three-phase asynchronous motor 902 is started to reset anyway, and continuous molding processing is achieved by repeating the above steps.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
