Technical Field

[0001] The invention belongs to the technical field of automobile parts production, and specifically is an injection mold for interior decoration parts of a door panel of a new energy automobile. Background Art

[0002] The interior decoration of new energy vehicle door panels is an important component of the interior decoration and function of the vehicle door panels. They not only improve the aesthetics of the vehicle interior, but also enhance the comfort and safety of the passengers. The door panel armrest is a kind of interior decoration of the vehicle door panels. It can provide support for the passengers' hands and improve riding comfort. The armrest needs to be formed by injection molding during the production and processing process.

[0003] The patent with announcement number CN214820479U discloses an injection molding mold for an automobile door panel armrest, which relates to the technical field of automobile parts production, and is designed to solve the problem of low processing efficiency of existing injection molding molds. The injection molding intermediate plate is located between the first molding mold and the second molding mold, and an injection molding machine nozzle is arranged in the middle of the upper end of the injection molding intermediate plate. A first hot runner is arranged inside the injection molding intermediate plate, and a second hot runner is arranged at both ends of the first hot runner. Both ends of the second hot runner are provided with a conical gate. An electric heating wire is installed inside the injection molding intermediate plate, and the electric heating wire is provided with a serpentine structure. The first molding mold and the second molding mold both include a lower mold base and an upper mold base, and the upper mold base is located at the upper end of the lower mold base. A molding cavity is arranged between the lower mold base and the upper mold base, and sliding rods are installed on both sides of the upper end of the lower mold base, and the sliding rods are slidably connected with the upper mold base, and a top plate is installed at the upper end of the sliding rods.

[0004] However, the above technical solution still has the following deficiencies in practical application: After the handrail is formed, although the injection molded parts can be lifted up by the ejector pin to achieve demolding of the injection molded parts, the lifted injection molded parts still need to be manually removed from the mold base to realize the collection work, which is not only laborious but also has the risk of being crushed. Moreover, even if the ejected injection molded parts can be moved away from the mold base by falling, the injection molded parts will still be in a messy pile due to falling. Usually, when multiple injection molded parts need to be molded at one time, it is necessary to visually inspect the injection quality of the injection molded parts after all the injection molded parts are molded to eliminate the injection molded parts with unqualified quality. When the injection molded parts are piled up in a messy way, it is not conducive to inspection. Moreover, after the quality inspection, the injection molded parts with qualified quality need to be collected and taken in an orderly manner so as to facilitate the subsequent further processing of the injection molded parts.

[0016] The beneficial effects of the present invention are as follows: 1. The injection mold for the interior trim of a door panel of a new energy vehicle described in the present invention drives the upper mold away from the lower mold after the raw material is cooled and formed in the molding cavity. At the same time, the demolding plate is driven to rise by the cylinder three, and the injection molded part is ejected by the demolding rod passing through the lower mold cavity, thereby realizing automatic demolding of the injection molded part, which is relatively convenient.

[0017] 2. The injection mold for the interior trim of a door panel of a new energy vehicle described in the present invention utilizes an injection molding part unloading mechanism and a positioning assembly. After the injection molding parts are ejected, they can be transferred to a storage plate for orderly placement and fixed. Since the multiple injection molding parts on the storage plate are relatively neat and orderly, workers can inspect the quality of the injection molding parts in turn, which is convenient and intuitive, and not prone to errors.

The entire collection and retrieval process is relatively orderly, which is convenient for the subsequent further processing of the injection molding parts.

[0018] 3. The injection mold for interior trim of a door panel of a new energy vehicle described in the present invention utilizes a push-down auxiliary component. When the push rod pushes down the injection molded parts on the storage plate, the upper plate and the lower plate are used to cover the injection molded parts, so that only the injection molded parts that need to be pushed down are exposed, and the remaining injection molded parts are blocked by the upper plate and the lower plate, thereby preventing the positioning blocks from being displaced due to external forces during the process of the injection molded parts being pushed down, causing the injection molded parts that should not have fallen to fall and mix with the injection molded parts in the remaining rows, thereby affecting the subsequent further processing of the injection molded parts.

[0019] 4. The injection mold for interior trim of door panels of new energy vehicles described in the present invention utilizes a clamping auxiliary component. When each row of injection-molded parts on a stock plate is clamped by the clamping jaws, the remaining injection-molded parts in each row are in a tightly fitted state, thereby reducing the spacing between the injection-molded parts and avoiding the difficulty in clamping when the clamping jaws clamp the injection-molded parts row by row.

[0025] In this embodiment, Figure 1 , Figure 4 , Figure 8 As shown, a hydraulic cylinder 6 is fixedly connected to one side of the upper end surface of the top plate 3, and the piston end of the hydraulic cylinder 6 is fixedly connected to the upper end of the upper mold 7. An injection molding mechanism 5 is arranged on one side of the upper end surface of the top plate 3. The discharge end of the injection molding mechanism 5 is connected to a connecting pipe 10, and the connecting pipe 10 is connected to a plurality of branch pipes 11, which penetrate the upper mold 7 and extend into the molding cavity.

[0026] A cylinder 3 57 is fixedly connected to one side of the lower end surface of the lower mold 4, a piston end of the cylinder 3 57 is fixedly connected to a stripping plate 55, and a lower end of a stripping rod 38 is fixedly connected to the stripping plate 55.

[0027] Specifically, the hydraulic cylinder 6 drives the upper mold 7 to slide on the limit rod 12 until the upper mold 7 is fitted with the lower mold 4. At this time, the upper mold 7 and the lower mold 4 cooperate with each other to form a plurality of complete handrail molding cavities, and then the injection molding mechanism 5 is used to inject the molten raw material into the molding cavity through the connecting pipe 10 and the branch pipe 11. After the raw material is cooled and formed in the molding cavity, the upper mold 7 is driven away from the lower mold 4. At the same time, the cylinder 3 57 is used to drive the demolding plate 55 to rise, and the demolding rod 38 passes through the lower mold cavity to eject the injection molded part, thereby realizing automatic demolding of the injection molded part, which is more convenient.

[0028] In this embodiment, Figure 5 , Figure 6 , Figure 9-11 , Fig.13 , Fig.14As shown, the lower end of the displacement rod 9 is threadedly connected with a threaded rod 4 34, and both ends of the threaded rod 4 34 are rotatably set on the workbench 1, and a motor 4 33 is fixedly connected to one side of the upper end surface of the workbench 1, and the output end of the motor 4 33 is fixedly connected to one end of the threaded rod 4 34, and one end of the slider 15 is threadedly connected with a threaded rod 14, and both ends of the threaded rod 14 are rotatably set on the groove plate 18, and one end of the groove plate 18 is fixedly connected with a motor 13, and the output end of the motor 13 is fixedly connected to one end of the threaded rod 14, and one end of the clamping plate 21 is threadedly connected with a threaded rod 2 19, and both ends of the threaded rod 2 19 are rotatably set on the connecting block 17, and one side of the connecting block 17 is fixedly connected with a motor 2 18, and the output end of the motor 2 18 is fixedly connected to one end of the threaded rod 2 19.

[0029] One side of the upper end of the support column 25 is fixedly connected to the motor three 24, and the output end of the motor three 24 is fixedly connected to one side of the material storage plate 23. One side of the lower end of the positioning block 32 is fixedly connected to the spring 56, and the end of the spring 56 away from the positioning block 32 is fixedly connected to the material storage plate 23.

[0030] A plurality of through holes 26 are provided on the material storage plate 23, and the through holes 26 are located between two adjacent positioning blocks 32. A slide rod 1 31 is fixedly connected to one side of the material storage plate 23, and a cylinder 29 is slidably connected to the slide rod 1 31. A lifting plate 27 is fixedly connected to the piston end of the cylinder 29, and a plurality of push rods 28 are fixedly connected to the upper end surface of the lifting plate 27. The push rods 28 can pass through the through holes 26. A threaded rod 3 30 is threadedly connected to one side of the cylinder 29, and one end of the threaded rod 3 30 is rotatably set on the material storage plate 23. A motor 9 54 is fixedly connected to one side of the material storage plate 23, and an output end of the motor 9 54 is fixedly connected to one end of the threaded rod 30.

[0031] Specifically, in the prior art, after the handrail is formed, although the injection molded part can be lifted up by an ejector pin to realize demolding of the injection molded part, the lifted injection molded part still needs to be manually removed from the mold base to realize the collection work, which is not only laborious but also has the risk of being crushed. Moreover, even if the ejected injection molded part can be separated from the mold base by falling, the injection molded part will still be in a messy pile due to falling. Usually, when multiple injection molded parts need to be molded at one time, it is necessary to visually inspect the injection quality of the injection molded parts after all the injection molded parts are molded to eliminate the injection molded parts with unqualified quality. However, when the injection molded parts are piled up in a messy manner, it is not conducive to inspection. Moreover, after the quality inspection is completed, the injection molded parts with qualified quality need to be collected and taken in an orderly manner so as to facilitate the subsequent further processing of the injection molded parts. However, the injection molded parts piled up in a messy manner are not conducive to collection and taking. Therefore, in order to solve the above problem, after the injection molded part is ejected, since the injection molded part is an armrest, and the armrest is concave, when the injection molded part is partially out of the molding cavity, a certain gap will be generated between it and the upper end surface of the lower mold 4, and the two ends of the injection molded part are still in the molding cavity. At this time, the injection molded part is in a vertical state, and then the motor 13 drives the threaded rod 14 to rotate to make the slider 15 move horizontally, and the positioning plate 20 extends into the gap between the injection molded part and the lower mold 4, and the clamping plate 21 is above the injection molded part, until all the clamping blocks 22 are aligned with the injection molded part, and then the motor 2 18 drives the threaded rod 14 to rotate. 9 is rotated to make the clamping plate 21 descend and clamp the injection molded part, then the cylinder 16 is used to drive the connecting block 17 to rise, and the injection molded part in the molding cavity is lifted up, and then the motor 4 33 drives the threaded rod 4 34 to rotate to make the displacement rod 9 move horizontally until the clamped injection molded part is aligned with a row of multiple positioning blocks 32, and then drive the multiple injection molded parts to descend. Since the upper side of the positioning block 32 is an inclined surface, the bottom of the injection molded part will squeeze the positioning block 32, so that the two positioning blocks 32 are separated from each other. At the same time, the injection molded part is clamped under the action of the spring 56, and then the above operation is repeated until the storage plate A sufficient number of injection molded parts are placed on the storage plate 23. At this time, the multiple injection molded parts on the storage plate 23 are relatively neat and orderly, and the workers can check the quality of the injection molded parts in turn, which is convenient and intuitive and less prone to mistakes. When the quality inspection work is completed and the injection molded parts need to be collected in a container, the injection molded parts can be placed under the storage plate 23, and then the motor three 24 is used to drive the storage plate 23 to turn ninety degrees, and the motor nine 54 drives the threaded rod three 30 to rotate so that the cylinder two 29 slides on the slide rod one 31, and the position of the lifting plate 27 is adjusted to align the ejector rod 28 with the through holes 26 in different rows. Then, the piston end of the second cylinder 29 drives the lifting plate 27 to move, so that the push rod 28 passes through the through hole 26, and the injection molded parts can be pushed off the storage plate 23 by the contact between the push rod 28 and the two ends of the injection molded parts, so that the injection molded parts can fall into the container. In some cases, injection molded parts of the same specifications but different colors will be formed in the molding cavity. Therefore, the colors of each row of injection molded parts on the storage plate 23 are different. The order of pushing down can be controlled to make the injection molded parts of different colors fall into different containers in turn, avoiding confusion. The entire collection and retrieval process is more orderly, which is convenient for the subsequent further processing of the injection molded parts.

[0032] In this embodiment, Figure 1 , Figure 7 , Fig.12 As shown, the workbench 1 is also provided with a push-down auxiliary component; The push-down auxiliary component includes a groove plate 41 fixedly connected to one side of the upper end surface of the workbench 1, the upper plate 2 is slidably connected to the sliding groove of the groove plate 41, and the lower plate 35 is inserted and slidably connected to one side of the workbench 1.

[0033] A threaded rod 6 40 is threadedly connected to one end of the upper plate 2, and both ends of the threaded rod 6 40 are rotatably set on the groove plate 2 41. A motor 6 39 is fixedly connected to the upper end of the groove plate 2 41, and the output end of the motor 6 39 is fixedly connected to one end of the threaded rod 6 40. A threaded rod 5 37 is threadedly connected to one side of the lower plate 35, and the upper end of the threaded rod 5 37 is rotatably set on the workbench 1. A motor 5 36 is fixedly connected to one side of the lower end surface of the workbench 1, and the output end of the motor 5 36 is fixedly connected to one end of the threaded rod 5 37.

[0034] Specifically, in the above embodiment, although the falling order of each row of injection molded parts can be controlled, since the injection molded parts are fixed under the action of elastic force, after the storage plate 23 is turned over, the positioning block 32 is easily displaced due to external forces, such as equipment vibration, accidental touch, etc., which will cause the injection molded parts that should not fall to fall and mix with the injection molded parts of the remaining rows, thereby affecting the subsequent further processing of the injection molded parts. Since the number of positioning blocks 32 is large, the use of the method of electrically locking the position of the positioning blocks 32 will also result in high costs; When the upper plate 2 and the lower plate 35 are moved together, the upper plate 2 and the lower plate 35 are moved together, so that the upper plate 2 and the lower plate 35 are moved together.

[0035] In this embodiment, Figure 2 , Figure 3 As shown, the workbench 1 is also provided with an injection molded part clamping auxiliary component; The injection molded part clamping auxiliary component includes a connecting plate 45 slidably connected to one side of the upper end surface of the workbench 1, two sliding rods 47 are slidably connected to the upper end of the connecting plate 45, and a lifting block 50 is fixedly connected to the upper end of the sliding rod 47. Two supporting rods 42 are fixedly connected to one side of the lifting block 50, and one end of the supporting rod 42 is fixedly connected to the limiting block 43. A rack rod 44 is slidably connected to one side of the lifting block 50, and one end of the rack rod 44 is fixedly connected to a push block 51.

[0036] A threaded rod 7 48 is threadedly connected to one side of the lower end of the connecting plate 45, and both ends of the threaded rod 7 48 are rotatably set on the workbench 1. A motor 7 49 is fixedly connected to one side of the upper end surface of the workbench 1, and the output end of the motor 7 49 is fixedly connected to one end of the threaded rod 7 48. An electric push rod 46 is fixedly connected to one side of the upper end of the connecting plate 45, and the piston end of the electric push rod 46 is fixedly connected to the lifting block 50. A gear 52 is rotatably set on one side of the lifting block 50, and the gear 52 is meshed with the gear block on the rack rod 44. A motor 8 53 is fixedly connected to one side of the lifting block 50, and the output end of the motor 8 53 is fixedly connected to the gear 52.

[0037] Specifically, in the above embodiment, although the injection molded parts on the storage plate 23 can be pushed down into the container for collection, in some cases, it is necessary to use the clamping claws to clamp the injection molded parts on the storage plate 23 row by row to meet different retrieval requirements. When the injection molded parts are subjected to quality inspection, some injection molded parts with unqualified quality will be eliminated, which will cause gaps of different sizes between a row of injection molded parts. When the clamping claws clamp the injection molded parts row by row, it will be difficult to clamp them. Therefore, in order to avoid this situation, when the clamping claws clamp each row of injection molded parts, the support column 25 can be driven to move on the slide rail by the control device. This moving method is a prior art and will not be described in detail. 3 can align the gap between each row of injection molded parts and the upper surface of the storage plate 23, and then drive the threaded rod 7 48 to rotate by the motor 7 49 to make the support rod 42 extend into the gap, and drive the lifting block 50 to move up by the electric push rod 46 to lift a row of injection molded parts, and then drive the gear 52 to rotate by the motor 8 53 to make the push block 51 approach the limit block 43. During the approaching process, the injection molded parts will fit closely to each other due to the push of the push block 51, and then, the clamping claws are used to take the injection molded parts on the support rod 42, thereby avoiding the situation that after the injection molded parts with unqualified quality are removed, the clamping claws are difficult to clamp the injection molded parts row by row due to the gaps of different sizes between each row of injection molded parts.

[0038] Working principle: The upper mold 7 is driven by the hydraulic cylinder 6 to slide on the limit rod 12 until the upper mold 7 is fitted with the lower mold 4. At this time, the upper mold 7 and the lower mold 4 cooperate with each other to form a plurality of complete handrail molding cavities, and then the injection molding mechanism 5 is used to inject the molten raw material into the molding cavity through the connecting pipe 10 and the branch pipe 11. After the raw material is cooled and formed in the molding cavity, the upper mold 7 is driven away from the lower mold 4. At the same time, the cylinder 3 57 is used to drive the stripping plate 55 to rise, and the injection molded part is ejected by the stripping rod 38 passing through the lower mold cavity, thereby realizing the automatic demolding of the injection molded part, which is more convenient. After the injection molded part is ejected, since the injection molded part is an handrail and the handrail is concave, when the injection molded part is partially separated from the molding cavity, a certain gap will be generated between it and the upper end surface of the lower mold 4, and the two ends of the injection molded part are still in the molding cavity. At this time, the injection molded part is in a vertical state, and then the motor 13 drives the threaded rod 14 to rotate to make the slider 15 move horizontally, and the positioning plate 20 extends to the injection molding The gap between the molded part and the lower mold 4 is formed, and the clamping plate 21 is above the injection molded part, until all the clamping blocks 22 are aligned with the injection molded part, and then the motor 2 18 drives the threaded rod 2 19 to rotate, so that the clamping plate 21 is lowered to clamp the injection molded part, and then the cylinder 16 is used to drive the connecting block 17 to rise, and the injection molded part in the molding cavity is lifted up, and then the motor 4 33 drives the threaded rod 4 34 to rotate to make the displacement rod 9 move horizontally until the clamped injection molded part is aligned with a row of multiple positioning blocks 32, and then drive the multiple injection molded parts to descend. Since the upper side of the positioning block 32 is an inclined surface, the bottom of the injection molded part will squeeze the positioning block 32, so that the two positioning blocks 32 are separated from each other. At the same time, the injection molded part is clamped under the action of the spring 56, and then the above operation is repeated until a sufficient number of injection molded parts are placed on the storage plate 23. At this time, the multiple injection molded parts on the storage plate 23 are relatively neat and orderly, and the workers can check the quality of the injection molded parts in turn, which is more convenient and intuitive, and less prone to errors.When the quality inspection work is completed and the injection molded parts need to be collected in a container, the injection molded parts can be placed under the storage plate 23, and then the motor 3 24 is used to drive the storage plate 23 to flip 90 degrees, and the motor 9 54 drives the threaded rod 30 to rotate to make the cylinder 29 slide on the slide rod 1 31, and the position of the lifting plate 27 is adjusted to make the push rod 28 align with the through holes 26 in different rows, and then the piston end of the cylinder 29 drives the lifting plate 27 to move so that the push rod 28 passes through the through hole 26, and the injection molded parts can be pushed off the storage plate 23 by the push rod 28 contacting the two ends of the injection molded parts, so that the injection molded parts can fall into the container, and in some cases, Injection molded parts with the same specifications but different colors will be formed in the molding cavity. Therefore, the colors of each row of injection molded parts on the storage plate 23 are different. The injection molded parts of different colors can be made to fall into different containers in sequence by controlling the order of pushing and dropping, so as to avoid confusion. The entire collection and retrieval process is relatively orderly, which is convenient for the subsequent further processing of the injection molded parts. When the storage plate 23 is turned over, one side of the injection molded part is flush with the end surface of one side of the upper plate 2 and the lower plate 35. According to the position of the injection molded part to be pushed down, the motor 6 39 and the motor 5 36 are started respectively. When the motor 5 36 drives the threaded rod 5 37 to rotate, the lower plate 35 rises, and when the motor 6 39 drives the threaded rod 6 40 to rotate, the upper plate 2 falls. The upper plate 2 and the lower plate 35 are positioned in such a way as to cover the injection molded parts so that only one row of injection molded parts is exposed between the upper plate 2 and the lower plate 35. At this time, the ejector rod 28 is used to push out a row of injection molded parts. Since the remaining injection molded parts are blocked by the upper plate 2 and the lower plate 35, the positioning block 32 is prevented from being displaced due to external force during the process of the injection molded parts being pushed down, causing the injection molded parts that should not have fallen to fall and be mixed with the injection molded parts of the remaining rows, thereby affecting the subsequent further processing of the injection molded parts. When the clamping jaws clamp each row of injection molded parts, the control device can be used to drive the support column 25 to move on the slide rail. This movement method is a prior art and will not be described in detail; the limit block 43 can be aligned with each The gap between the row of injection molded parts and the upper surface of the storage plate 23 is then driven by the motor 7 49 to rotate the threaded rod 7 48, so that the support rod 42 extends into the gap, and the electric push rod 46 drives the lifting block 50 to move up, and a row of injection molded parts is lifted, and then the motor 8 53 drives the gear 52 to rotate, so that the push block 51 approaches the limit block 43. During the approaching process, the injection molded parts will fit closely to each other due to the push of the push block 51, and then the clamping claws are used to take the injection molded parts on the support rod 42, thereby avoiding the situation that after the injection molded parts with unqualified quality are removed, the gaps of different sizes between each row of injection molded parts are generated, and the clamping claws are difficult to clamp the injection molded parts row by row. ;
