Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts production, and specifically relates to an injection mold for the interior trim parts of a new energy vehicle door panel. Background Art

[0002] The interior trim parts of a new energy vehicle door panel are important components that constitute the interior decoration and functions of the vehicle door. They not only enhance the aesthetics of the interior of the vehicle but also improve the comfort and safety of passengers. As a type of interior trim part of the vehicle door, the door armrest can provide support for the hands of passengers and improve the riding comfort. During the production and processing of the armrest, it needs to be formed by injection molding.

[0003] The patent with the publication number CN214820479U discloses an injection molding die for an automotive door armrest, which relates to the technical field of automotive parts production and aims to solve the problem of low processing efficiency of the existing injection molding die. The injection middle plate is located between the first molding die and the second molding die. An injection machine nozzle is arranged in the middle of the upper end of the injection middle plate. A first hot runner is arranged inside the injection middle plate. Second hot runners are arranged at both ends of the first hot runner. Conical gate openings are arranged at both ends of the second hot runner. An electric heating wire is installed inside the injection middle plate, and the electric heating wire is arranged in a serpentine structure. Both the first molding die and the second molding die include a lower die base and an upper die base. The upper die base is located above the lower die base. A molding cavity is arranged between the lower die base and the upper die base. Slide rods are installed on both sides of the upper end of the lower die base. The slide rods are slidably connected with the upper die base. A top plate is installed at the upper end of the slide rods.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] After the armrest is formed, although the injection molded part can be pushed up by the ejector pin to achieve demolding of the injection molded part, however, the injection molded part after being pushed up still needs to be manually removed from the die base to complete 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 moved away from the die 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 formed at one time, after all the injection molded parts are formed, the injection quality of the injection molded parts needs to be visually inspected to remove the unqualified injection molded parts. When the injection molded parts are in a messy pile, it is not conducive to inspection. And after the quality inspection, the qualified injection molded parts need to be collected and taken out in an orderly manner for subsequent further processing of the injection molded parts, while the messy pile of injection molded parts is not conducive to collection and taking out.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1.

Moreover, when it is necessary to collect the injection molding parts on the storage plate, the storage plate can be flipped over, and the injection molding parts can be pushed off the storage plate by contacting the ejector rod with both ends of the injection molding parts, so that the injection molding parts fall into a container. Moreover, when the colors of each row of injection molding parts on the storage plate are different, the order of pushing down can be controlled to make the injection molding parts of different colors fall into different containers in turn, 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 molding parts.

[0025] 3. For an injection mold for the interior trim of a new energy vehicle door panel according to the present invention, by using the pushing-down auxiliary component, when the ejector rod pushes down the injection molded parts on the stock plate, the upper plate and the lower plate can cover the injection molded parts, only exposing the injection molded parts that need to be pushed down, and the remaining injection molded parts are blocked by the upper plate and the lower plate, avoiding the displacement of the positioning block due to external force during the process of pushing down the injection molded parts, resulting in the dropping of injection molded parts that should not have dropped and mixing with the injection molded parts in the other rows, thereby affecting the subsequent further processing of the injection molded parts.

[0026] 4. For an injection mold for the interior trim of a new energy vehicle door panel according to the present invention, by using the clamping auxiliary component, when clamping each row of injection molded parts on the stock plate through the clamping jaws, the remaining injection molded parts in each row are in a tightly fitting state, reducing the spacing between the injection molded parts and avoiding the situation of difficult clamping when the clamping jaws clamp the injection molded parts row by row.

[0044] Please refer to Figures 1-14 , the present invention provides a technical solution: an injection mold for an interior trim part of a new energy vehicle door panel, including a workbench 1, a lower mold 4 is fixedly connected to one side of the upper end surface of the workbench 1, limiting rods 12 are fixedly connected to the four corners of the upper end surface of the lower mold 4, a top plate 3 is fixedly connected to the upper ends of the limiting rods 12, an upper mold 7 is slidably connected to the limiting rods 12, a plurality of laterally arranged forming cavities are provided at the upper end of the lower mold 4 and the lower end of the upper mold 7, a plurality of demolding rods 38 are inserted and slidably connected to the bottom of the lower mold 4, and when the lower mold 4 is attached to the upper mold 7, a plurality of complete armrest forming cavities can be formed. An injection part blanking mechanism is also provided on the workbench 1;

[0045] The injection molding part blanking mechanism includes a displacement rod 9 slidably connected to one side of the upper end surface of the workbench 1. A first groove plate 8 is fixedly connected to the upper end of the displacement rod 9. A slider 15 is slidably connected to the chute of the first groove plate 8. A first cylinder 16 is fixedly connected to one side of the upper end surface of the slider 15. A connecting block 17 is fixedly connected to the piston end of the first cylinder 16. A positioning plate 20 is fixedly connected to one side of the lower end of the connecting block 17. A clamping plate 21 is slidably connected to the chute of the connecting block 17. A plurality of clamping blocks 22 are fixedly connected in a transverse arrangement to the mutually approaching end faces of the positioning plate 20 and the clamping plate 21.

[0046] A plurality of groups of positioning components are further arranged on the storage plate 23;

[0047] The positioning component includes two positioning blocks 32 slidably connected to the upper end surface of the storage plate 23.

[0048] In this embodiment, as Figure 1 , Figure 4 , Figure 8 shown, a hydraulic cylinder 6 is fixedly connected to one side of the upper end surface of the top plate 3. 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 communicated with a connecting pipe 10. A plurality of branch pipes 11 are communicated with the connecting pipe 10. The branch pipes 11 penetrate through the upper mold 7 and extend into the molding cavity.

[0049] A third cylinder 57 is fixedly connected to one side of the lower end surface of the lower mold 4. A demolding plate 55 is fixedly connected to the piston end of the third cylinder 57. The lower end of the demolding rod 38 is fixedly connected to the demolding plate 55.

[0050] Specifically, the upper mold 7 is driven by the hydraulic cylinder 6 to slide on the limiting rod 12 until the upper mold 7 fits 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 armrest molding cavities. Then, the molten raw material is injected into the molding cavity through the connecting pipe 10 and the branch pipes 11 by using the injection molding mechanism 5. After the raw material is cooled and formed in the molding cavity, the upper mold 7 is driven to move away from the lower mold 4. At the same time, the demolding plate 55 is driven to rise by using the third cylinder 57, and the injection molding part is ejected by the demolding rod 38 passing through the lower mold cavity, thus realizing the automatic demolding of the injection molding part, which is relatively convenient.

[0051] In this embodiment, as Figure 5 , Figure 6 , Figures 9-11 , Figure 13 , Figure 14As shown, a threaded rod four 34 is threadedly connected to the lower end of the displacement rod 9. Both ends of the threaded rod four 34 are rotatably arranged on the workbench 1. One side of the upper end surface of the workbench 1 is fixedly connected with a motor four 33. The output end of the motor four 33 is fixedly connected to one end of the threaded rod four 34. One end of a slider 15 is threadedly connected to a threaded rod one 14. Both ends of the threaded rod one 14 are rotatably arranged on a groove plate one 8. One end of the groove plate one 8 is fixedly connected with a motor one 13. The output end of the motor one 13 is fixedly connected to one end of the threaded rod one 14. One end of a clamping plate 21 is threadedly connected to a threaded rod two 19. Both ends of the threaded rod two 19 are rotatably arranged on a connecting block 17. One side of the connecting block 17 is fixedly connected with a motor two 18. The output end of the motor two 18 is fixedly connected to one end of the threaded rod two 19.

[0052] One side of the upper end of the support column 25 is fixedly connected with a motor three 24. The output end of the motor three 24 is fixedly connected to one side of the storage plate 23. One side of the lower end of the positioning block 32 is fixedly connected with a spring 56. The end of the spring 56 away from the positioning block 32 is fixedly connected to the storage plate 23.

[0053] A plurality of through holes 26 are provided on the storage plate 23, and the through holes 26 are located between two adjacent positioning blocks 32. One side of the storage plate 23 is fixedly connected with a slide bar one 31. A cylinder two 29 is slidably connected to the slide bar one 31. The piston end of the cylinder two 29 is fixedly connected with a lifting plate 27. A plurality of ejector rods 28 are fixedly connected to the upper end surface of the lifting plate 27. The ejector rods 28 can pass through the through holes 26. One side of the cylinder two 29 is threadedly connected to a threaded rod three 30. One end of the threaded rod three 30 is rotatably arranged on the storage plate 23. One side of the storage plate 23 is fixedly connected with a motor nine 54. The output end of the motor nine 54 is fixedly connected to one end of the threaded rod three 30.

[0054] Specifically, in the prior art, after the armrest is formed, although the injection molded part can be lifted by the ejector pin to realize the demolding of the injection molded part, however, the lifted injection molded part still needs to be manually removed from the mold base to complete 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 parts will still be in a messy pile due to falling. Usually, when multiple injection molded parts need to be formed at one time, after all the injection molded parts are formed, the injection quality of the injection molded parts needs to be visually inspected to eliminate the unqualified injection molded parts. When the injection molded parts are in a messy pile, it is not conducive to inspection. And after the quality inspection, the qualified injection molded parts need to be collected and taken out in an orderly manner for subsequent further processing of the injection molded parts, while the messy pile of injection molded parts is not conducive to collection and taking out.

[0055] 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.

[0056] In this embodiment, Figure 1 , Figure 7 , Figure 12 As shown, the workbench 1 is also provided with a push-down auxiliary component;

[0057] 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.

[0058] One end of the upper plate 2 is threadedly connected to a sixth threaded rod 40. Both ends of the sixth threaded rod 40 are rotatably arranged on the second groove plate 41. The upper end of the second groove plate 41 is fixedly connected to a sixth motor 39. The output end of the sixth motor 39 is fixedly connected to one end of the sixth threaded rod 40. One side of the lower plate 35 is threadedly connected to a fifth threaded rod 37. The upper end of the fifth threaded rod 37 is rotatably arranged on the workbench 1. One side of the lower end surface of the workbench 1 is fixedly connected to a fifth motor 36. The output end of the fifth motor 36 is fixedly connected to one end of the fifth threaded rod 37.

[0059] Specifically, in the above embodiment, although the dropping order of each row of injection molded parts can be controlled, however, since the injection molded parts are fixed under the action of elastic force, so, after the storage plate 23 is flipped, the positioning block 32 is likely to be displaced due to external forces, such as factors like equipment vibration and accidental touch. This will cause the injection molded parts that should not have dropped to drop and mix with the injection molded parts of the other rows, thus affecting the subsequent further processing of the injection molded parts. And since the number of positioning blocks 32 is large, the method of electrically controlling and locking the position of the positioning block 32 will also result in a high cost.

[0060] Therefore, to solve the above problems, when in use in this embodiment, after the storage plate 23 is flipped, one side of the injection molded part is flush with the end faces 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 as needed, the sixth motor 39 and the fifth motor 36 are respectively started. When the fifth motor 36 drives the fifth threaded rod 37 to rotate, the lower plate 35 rises. When the sixth motor 39 drives the sixth threaded rod 40 to rotate, the upper plate 2 descends. Then, the injection molded parts can be covered by changing the positions of the upper plate 2 and the lower plate 35, 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 one row of injection molded parts. Since the other injection molded parts are blocked by the upper plate 2 and the lower plate 35, it is avoided that during the process of pushing out the injection molded parts, the positioning block 32 is displaced due to external forces, resulting in the injection molded parts that should not have dropped to drop and mix with the injection molded parts of the other rows, thereby affecting the subsequent further processing of the injection molded parts.

[0061] In this embodiment, as Figure 2 、 Figure 3 shown, an injection molded part clamping and assisting assembly is further arranged on the workbench 1;

[0062] The injection molded part clamping and assisting assembly includes a connecting plate 45 slidably connected to one side of the upper end surface of the workbench 1. Two second sliding rods 47 are slidably connected to the upper end of the connecting plate 45. The upper ends of the second sliding rods 47 are fixedly connected to a lifting block 50. One side of the lifting block 50 is fixedly connected to two supporting rods 42. One end of the supporting rods 42 is fixedly connected to a limiting block 43. One side of the lifting block 50 is slidably connected to a rack rod 44. One end of the rack rod 44 is fixedly connected to a pushing block 51.

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.

[0064] 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.

[0065] Working principle: The hydraulic cylinder 6 drives the upper mold 7 to slide on the limiting rod 12 until the upper mold 7 fits 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 armrest forming cavities. Then, the injection molding mechanism 5 injects the molten raw material into the forming cavities through the connecting pipe 10 and the branch pipe 11. When the raw material cools and forms in the forming cavities, the upper mold 7 is driven away from the lower mold 4. At the same time, the cylinder three 57 drives the demolding plate 55 to rise, and the injection molded part is ejected by the demolding rod 38 passing through the lower mold cavity, thus realizing the automatic demolding of the injection molded part, which is relatively convenient. 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 partially disengages from the forming cavity, there will be a certain gap between it and the upper end face of the lower mold 4, and both ends of the injection molded part remain in the forming cavity. At this time, the injection molded part is in a vertical state. Then, the motor one 13 drives the lead screw one 14 to rotate to make the slider 15 move horizontally. 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. Then, the motor two 18 drives the lead screw two 19 to rotate to make the clamping plate 21 descend and clamp the injection molded part. Then, the cylinder one 16 drives the connecting block 17 to rise to lift the injection molded part in the forming cavity upward. Then, the motor four 33 drives the lead screw four 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. Then, the multiple injection molded parts are driven to descend. Since the upper side of the positioning block 32 is a slope, the bottom of the injection molded part will squeeze the positioning block 32 to make the two positioning blocks 32 move away from each other. At the same time, the injection molded part is clamped under the action of the spring 56. Then, the above operations are repeated until there are enough injection molded parts 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 worker can sequentially detect the quality of the injection molded parts, which is relatively convenient, intuitive and not easy to make 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 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. ;
