[0012] Further, a first serpentine infusion channel is provided on the lifting plate, and the first serpentine infusion channel communicates with the inner cavities of the tube bodies of a plurality of infusion tubes.

[0013] Further, a first liquid extrusion rod is connected to the upper surface of the upper mold. The first liquid extrusion rod includes a guide rod connected to the lower surface of the top plate and a hollow cylinder slidably connected to the bottom end of the guide rod. The inner cavity of the hollow cylinder communicates with the first serpentine infusion channel.

[0014] Further, a second liquid extrusion rod is connected to one end of the upper mold away from the first liquid extrusion rod. The structure of the second liquid extrusion rod is the same as that of the first liquid extrusion rod. The hollow cylinder in the second liquid extrusion rod is connected to the lower surface of the top plate, and the guide rod in the second liquid extrusion rod is connected to the upper surface of the upper mold.

[0015] Further, a liquid passage is provided on the column body of the ejector pin, and the liquid passage is connected to the hollow cylinder in the second liquid extrusion rod through a pipeline.

[0016] Further, a second groove for accommodating the second ejector rod is provided on the lower mold. The structure of the second ejector rod is the same as that of the first ejector rod. The infusion tube in the second ejector rod communicates with a second serpentine infusion channel.

[0017] According to the above technical solution of a stamping die for an air conditioner dust-proof gasket, an air conditioner dust-proof gasket stamping process will also be provided, including the following steps:

[0018] Step 1: Accurately place the raw material on the lower mold, start the cylinder, and the cylinder pushes the lifting plate and the upper mold to quickly move downward.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration.

[0037] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0038] The embodiment of the present application provides a stamping die for an air - conditioner dust - proof gasket. The schematic diagram of the stamping die for the air - conditioner dust - proof gasket is as Figure 1-8 shown. The stamping die for the air - conditioner dust - proof gasket includes a base 10. At multiple top corners of the upper surface of the base 10, top columns 20 are connected. The tops of the multiple top columns 20 are connected to a top plate 30. An upper die mechanism 40 is connected to the plate body of the top plate 30, and a lower die mechanism 50 is provided at the bottom end of the upper die mechanism 40;

[0039] The upper die mechanism 40 includes a cylinder 41 connected to the upper surface of the top plate 30, a lifting plate 42 connected to the execution end of the cylinder 41, and an upper die 43 connected to the lower surface of the lifting plate 42. A plurality of first ejector rods 44 are connected to the upper die 43;

[0040] The lower die mechanism 50 includes a lower die 51 connected to the upper surface of the base 10, and a second ejector rod 52 connected to the bottom end of the lower die 51.

[0041] It should be noted that in this embodiment, the base 10 provides a stable support foundation for the entire die. The ejector post 20 connects the base 10 and the top plate 30 to build a solid frame structure. The top plate 30 is used to install the upper die mechanism 40. The cylinder 41 is installed on the top plate 30, and its actuator drives the lifting plate 42 and the upper die 43 connected thereto to perform reciprocating up and down movements. The lower die 51 of the lower die mechanism 50 is fixed on the base 10 and cooperates with the upper die 43 to complete the stamping operation. During stamping, the cylinder 41 pushes the upper die 43 downward to apply pressure to the raw material placed therebetween with the lower die 51, causing it to undergo plastic deformation, thereby stamping out the air-conditioning dust-proof gasket.

[0042] Optionally, please refer to the appendix Figure 4 , a plurality of first grooves 431 corresponding to the first ejector rods 44 are provided on the upper die 43, and the first ejector rods 44 are fitted with the grooves of the first grooves 431.

[0043] In this embodiment, the first grooves 431 on the upper die 43 correspond to and fit with the first ejector rods 44. After stamping is completed, as the upper die 43 rises, the relevant structure of the first ejector rod 44 acts to eject the first ejector rod 44 from the first groove 431 to lift the gasket adhered to the upper die 43. The first groove 431 provides a space for the installation and positioning of the first ejector rod 44, ensuring that the first ejector rod 44 can be received in the upper die 43 when not working, without affecting the stamping operation. After stamping is completed, it can accurately eject the first ejector rod 44, effectively preventing the gasket from adhering to the upper die 43, improving the demolding effect of the product, and reducing product damage and defective rate caused by adhesion.

[0044] Optionally, please refer to the appendix Figure 4 , the first ejector rod 44 includes an infusion tube 441 inserted into the groove of the first groove 431, and a liquid storage sleeve 442 sleeved outside one end of the infusion tube 441, and the liquid storage sleeve 442 is fitted with the groove of the first groove 431.

[0045] In this embodiment, the infusion tube 441 of the first ejector rod 44 is inserted into the first groove 431, and the liquid storage sleeve 442 is sleeved on one end of the infusion tube 441 and fits with the first groove 431. When the upper die 43 rises after stamping, the relevant liquid extrusion structure extrudes the liquid, and the liquid enters the liquid storage sleeve 442 through the infusion tube 441, pushing the infusion tube 441 to extend outwards, thereby ejecting the first ejector rod 44. This structural design utilizes the pressure transmission of the liquid to achieve the ejection of the first ejector rod 44, featuring rapid response and uniform ejection force. The cooperation between the infusion tube 441 and the liquid storage sleeve 442 not only ensures the stability of the ejector rod ejection but also can buffer the impact force during ejection to a certain extent, avoiding damage to the gasket and further improving the product quality.

[0046] Optionally, please refer to the appendix Figure 4 , the first ejector rod 44 further includes an anti - detachment ring 443 connected to the end of the infusion tube 441 extending into the liquid storage sleeve 442, and the anti - detachment ring 443 is slidably connected to the inner wall of the barrel of the liquid storage sleeve 442.

[0047] In this embodiment, the anti - detachment ring 443 is connected to the end of the infusion tube 441 extending into the liquid storage sleeve 442 and is slidably connected to the inner wall of the barrel of the liquid storage sleeve 442. During the process of the infusion tube 441 extending outwards or resetting under the liquid pressure, the anti - detachment ring 443 plays a role in preventing the infusion tube 441 from detaching from the liquid storage sleeve 442. The setting of the anti - detachment ring 443 enhances the reliability of the structure of the first ejector rod 44, ensuring that the infusion tube 441 and the liquid storage sleeve 442 always remain connected during multiple ejection and reset processes, guaranteeing the normal operation of the first ejector rod 44, reducing equipment failures caused by structural loosening or detachment, and improving the service life and stability of the mold.

[0048] Optionally, please refer to the appendix Figure 4 , the lifting plate 42 is provided with a first serpentine infusion flow channel 432, and the first serpentine infusion flow channel 432 is communicated with the inner cavities of the tubes of a plurality of infusion tubes 441.

[0049] In this embodiment, the first serpentine infusion flow channel 432 on the lifting plate 42 is communicated with the inner cavities of the tubes of a plurality of infusion tubes 441. When the first liquid extrusion rod 433 and the second liquid extrusion rod 434 act to extrude the liquid, the liquid is divided into each infusion tube 441 through the first serpentine infusion flow channel 432, realizing the synchronous drive of a plurality of first ejector rods 44. The design of the first serpentine infusion flow channel 432 enables the liquid to be evenly distributed to each infusion tube 441, ensuring the consistency and synchronism of the ejection of a plurality of first ejector rods 44. This helps to lift the gasket more comprehensively and evenly, preventing the gasket from deforming or being damaged due to uneven local stress, and further improving the product quality and demolding effect.

[0050] Optionally, please refer to the appendix Figure 2and 7 On the upper surface of the upper mold 43, a first liquid extrusion rod 433 is connected. The first liquid extrusion rod 433 includes a guide rod 4331 connected to the lower surface of the top plate 30 and a hollow cylinder 4332 slidably connected to the bottom end of the guide rod 4331. The inner cavity of the hollow cylinder 4332 communicates with the first serpentine liquid flow channel 432.

[0051] In this embodiment, the guide rod 4331 of the first liquid extrusion rod 433 is connected to the lower surface of the top plate 30. The hollow cylinder 4332 is slidably connected to the bottom end of the guide rod 4331 and its inner cavity communicates with the first serpentine liquid flow channel 432. When the air cylinder 41 drives the upper mold 43 to rise, the guide rod 4331 slides upward relative to the hollow cylinder 4332, squeezing the liquid in the hollow cylinder 4332. The liquid drives the first ejector rod 44 to eject through the first serpentine liquid flow channel 432. The structural design of the first liquid extrusion rod 433 cleverly utilizes the movement when the upper mold 43 rises, converts it into the power for squeezing the liquid, and realizes the automatic ejection of the first ejector rod 44. Without an additional power device, the mold structure is simplified, the equipment cost and maintenance difficulty are reduced, and at the same time, the reliability and stability of the ejection action are improved.

[0052] Optionally, please refer to the appendix Figure 4 and 8 At one end of the upper mold 43 away from the first liquid extrusion rod 433, a second liquid extrusion rod 434 is connected. The structure of the second liquid extrusion rod 434 is the same as that of the first liquid extrusion rod 433. The hollow cylinder 4332 in the second liquid extrusion rod 434 is connected to the lower surface of the top plate 30, and the guide rod 4331 in the second liquid extrusion rod 434 is connected to the upper surface of the upper mold 43.

[0053] In this embodiment, the structure of the second liquid extrusion rod 434 is the same as that of the first liquid extrusion rod 433, but its connection method is opposite to that of the first liquid extrusion rod 433. When the hollow cylinder 4332 is connected to the lower surface of the top plate 30 and the guide rod 4331 is connected to the upper surface of the upper mold 43, as the upper mold 43 rises, the guide rod 4331 slides upward relative to the hollow cylinder 4332, also squeezing the liquid in the hollow cylinder 4332. The liquid drives the first ejector rod 44 to eject through the relevant flow channels. The second liquid extrusion rod 434 and the first liquid extrusion rod 433 cooperate with each other, providing extrusion forces from different directions, enhancing the liquid extrusion effect, and ensuring that the first ejector rod 44 can obtain sufficient ejection power. At the same time, this symmetric structural design makes the mold more evenly stressed during operation, improving the overall stability and service life of the mold.

[0054] Optionally, please refer to the appendix Figure 8 On the column body of the ejector post 20, a liquid flow channel 21 is provided. The liquid flow channel 21 is connected to the hollow cylinder 4332 in the second liquid extrusion rod 434 through a pipeline.

[0055] In this embodiment, the liquid flow channel 21 on the top column 20 is connected to the hollow cylinder 4332 in the second extrusion rod 434 through a pipeline. When the first extrusion rod 433 and the second extrusion rod 434 extrude the liquid, part of the liquid is transported to the second serpentine liquid flow channel 512 of the lower mold 51 through the liquid flow channel 21, which is used to drive the second ejector rod 52 to eject. The setting of the liquid flow channel 21 realizes the coordinated work of the upper mold mechanism and the lower mold mechanism during the ejection process, and reasonably utilizes the liquid generated by the extrusion of the upper mold mechanism in the ejection action of the lower mold mechanism. This not only simplifies the power system of the mold, but also ensures a certain synchronism between the ejection actions of the upper and lower molds, improving the demolding efficiency and taking convenience of the gasket.

[0056] Optionally, referring to the attached drawings, the lower mold 51 is provided with a second groove 511 for accommodating the second ejector rod 52. The structure of the second ejector rod 52 is the same as that of the first ejector rod 44. The liquid infusion pipe 441 in the second ejector rod 52 is communicated with the second serpentine liquid flow channel 512. The second serpentine liquid flow channel 512 is arranged on the lower mold 51, and the second serpentine liquid flow channel 512 is communicated with the liquid flow channel 21.

[0057] In this embodiment, the second groove 511 on the lower mold 51 is used to accommodate the second ejector rod 52, and the structure of the second ejector rod 52 is the same as that of the first ejector rod 44. When the liquid enters the second serpentine liquid flow channel 512 through the liquid flow channel 21, it pushes the liquid infusion pipe 441 in the second ejector rod 52 to extend outwards, ejecting the second ejector rod 52 from the second groove 511 and lifting the gasket on the lower mold 51. The setting of the second ejector rod 52 corresponds to that of the first ejector rod 44, further improving the demolding and taking functions of the gasket. Lifting the gasket from below the lower mold 51 and acting together with the first ejector rod 44 on the upper mold 43 can more effectively prevent the gasket from adhering to the mold, facilitating the operator to take the gasket and improving the production efficiency and product quality.

[0058] Based on the same inventive concept, this embodiment also provides a stamping process for an air-conditioning dust-proof gasket, including the following steps:

[0059] Step 1, accurately place the raw material on the lower mold 51, start the cylinder 41, and the cylinder 41 pushes the lifting plate 42 and the upper mold 43 to quickly move downward. The upper mold 43 is closely matched with the lower mold 51, applying a preset pressure to the raw material, so that the raw material undergoes plastic deformation under the action of the pressure, completing the stamping of the air-conditioning dust-proof gasket.

[0060] Step 2: After stamping is completed, the air cylinder 41 drives the upper die 43 to rise. The first liquid extrusion rod 433 and the second liquid extrusion rod 434 act to extrude the liquid. The liquid enters the infusion tube 441 through the first serpentine infusion channel 432, pushing the first ejector rod 44 out of the first groove 431 and lifting the gasket adhered to the upper die 43. Meanwhile, part of the liquid enters the second serpentine infusion channel 512 of the lower die 51 through the liquid passage 21, pushing the second ejector rod 52 out of the second groove 511 and lifting the gasket on the lower die 51.

[0061] Step 3: The operator promptly takes the lifted air-conditioning dust-proof gasket and places it in the designated collection area. Check the appearance and size of the gasket, and store the qualified products and unqualified products separately.

[0062] Step 4: After all the gaskets are taken, the air cylinder 41 acts again to drive the upper die 43 to descend. The first liquid extrusion rod 433 and the second liquid extrusion rod 434 return to their initial states, the liquid flows back, and the first ejector rod 44 and the second ejector rod 52 reset to the grooves, preparing for the next stamping operation.

[0063] The specific operation method of the present invention is as follows:

[0064] When using the stamping die for the air-conditioning dust-proof gasket, start the air cylinder 41. The actuator end of the air cylinder 41 pushes the lifting plate 42 and the upper die 43 to move downward. The upper die 43 cooperates with the lower die 51 to stamp the raw material placed on the lower die 51, completing the processing of the air-conditioning dust-proof gasket.

[0065] After stamping is completed, the air cylinder 41 drives the upper die 43 to rise. As the upper die 43 rises, the relative positions of the first liquid extrusion rod 433 and the second liquid extrusion rod 434 change. Taking the first liquid extrusion rod 433 as an example, the guide rod 4331 slides upward relative to the hollow cylinder 4332, extruding the liquid such as lubricating oil in the hollow cylinder 4332. The liquid enters a plurality of infusion tubes 441 through the first serpentine infusion channel 432, pushing the infusion tubes 441 to extend outward in the liquid storage sleeve 442, and then ejecting the first ejector rod 44 out of the first groove 431. After the first ejector rod 44 is ejected, it lifts the gasket adhered to the upper die 43, preventing the gasket from adhering to the upper die 43.

[0066] During the process of the first liquid extrusion rod 433 and the second liquid extrusion rod 434 extruding the liquid, part of the liquid enters the second serpentine infusion channel 512 of the lower die 51 through the liquid passage 21. The liquid pushes the infusion tubes 441 in the second ejector rod 52 to extend outward, ejecting the second ejector rod 52 out of the second groove 511 and lifting the gasket on the lower die 51, further facilitating the taking of the gasket.

[0067] After the gasket is taken out, the cylinder 41 operates again, driving the upper die 43 to descend. The first liquid extrusion rod 433 and the second liquid extrusion rod 434 return to their initial states, and the liquid flows back. The first ejector rod 44 and the second ejector rod 52 also reset accordingly and return to the grooves to prepare for the next stamping operation.

[0068] The above has described the present invention exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.

A stamping process for an air conditioner dustproof gasket, applied to the stamping die for an air conditioner dustproof gasket according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: accurately place the raw material on the lower mold (51), start the cylinder (41), and the cylinder (41) pushes the lifting plate (42) and the upper mold (43) to move downward quickly. The upper mold (43) and the lower mold (51) are closely matched to apply a preset pressure to the raw material, so that the raw material undergoes plastic deformation under the pressure, thereby completing the stamping and forming of the air conditioner dustproof gasket; Step 2: After the stamping is completed, the cylinder (41) drives the upper mold (43) to rise, and the first squeezing rod (433) and the second squeezing rod (434) are activated to squeeze the liquid, and the liquid enters the infusion tube (441) through the first serpentine infusion channel (432), pushing the first push rod (44) out of the first groove (431), and lifting the gasket adhered to the upper mold (43); at the same time, part of the liquid enters the second serpentine infusion channel (512) through the liquid flow channel (21), pushing the second push rod (52) out of the second groove (511), and lifting the gasket on the lower mold (51); Step three: The operator promptly takes the lifted air conditioner dustproof gasket and places it in the designated collection area; checks the appearance and size of the gasket, and sorts and stores qualified products and unqualified products. Step 4: After the gasket is removed, the cylinder (41) is activated again to drive the upper mold (43) to descend, the first extrusion rod (433) and the second extrusion rod (434) are restored to their initial state, the liquid flows back, and the first ejector rod (44) and the second ejector rod (52) are reset to the groove to prepare for the next stamping operation.
