Description

Technical Field

[0001] This utility model relates to the field of air conditioner manufacturing technology, and in particular to an air conditioner pre-assembly pressing tool. Background Technology

[0002] In the pre-assembly production of air conditioners, the adhesive bonding process for components such as air guides, handheld devices, panels, and control boards is crucial to product quality. In existing technologies, to ensure a tight bond under high pressure and avoid the risk of detachment, a common method is to use a contour mold combined with a cylinder for bonding: upper and lower contour molds are designed according to the product's appearance, and the upper mold is driven downwards by a cylinder to make high-pressure contact with the fixed lower mold to complete the bonding. In current production processes, the molds used in the bonding fixtures are directly fixed to the cylinders, requiring the entire fixture to be replaced when switching production models. This necessitates purchasing different fixtures for different models, increasing tooling costs. Furthermore, the inability to quickly switch between models results in low work efficiency and high labor intensity for employees.

[0003] Therefore, it is necessary to improve the pressing tooling of the existing air conditioner pre-installation process to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, the purpose of this utility model is to provide an air conditioner pre-assembly pressing tool. The upper and lower molds of this tool are both detachable, and it has a wide range of applications, which can meet the pressing needs of different products.

[0005] An air conditioner pre-assembly pressing tooling includes:

[0006] A base frame is provided with a first driving device and an upper mold structure. The upper mold structure is detachably mounted on the output end of the first driving device. The first driving device drives the upper mold structure to move up and down on the base frame. A first contouring position is provided at the bottom of the upper mold structure.

[0007] The base frame is also provided with a detachable lower mold structure, and the lower mold structure is provided with a second contouring position, which corresponds to the first contouring position.

[0008] When using this pre-installed air conditioner pressing fixture, select the appropriate upper and lower mold structures according to the target product type. Install the upper mold structure onto the output end of the first drive device and secure it firmly using the upper mold positioning and locking mechanism. Place the lower mold structure in the designated position on the base frame and precisely position and lock it using the lower mold positioning and locking mechanism. Start the first drive device; the upper mold structure moves downward with the output end of the first drive device, and the first and second contouring positions cooperate to perform high-pressure pressing on the product, completing the pressing process.

[0009] Because both the upper and lower mold structures are detachable, a single base frame and first drive unit can accommodate molds for multiple models. Companies no longer need to purchase a complete set of tooling for each model, significantly reducing tooling procurement costs. For example, companies producing multiple air conditioner models would previously need a complete set of tooling for each model, resulting in high costs. However, with this tooling, only a base frame and drive unit need to be purchased, and the upper and lower molds can be replaced as needed, significantly reducing costs.

[0010] The detachable structure makes mold changes more convenient and faster. When switching between production of different product models, there is no need to change the entire tooling; only the corresponding upper and lower molds need to be replaced, which greatly shortens turnaround time and improves production efficiency.

[0011] In a preferred embodiment of this utility model, a second driving structure is provided on the base frame. The second driving structure includes a guide rail and a linear driving device. The guide rail is located below the first driving device, and the lower mold structure is slidably disposed on the guide rail.

[0012] The linear drive device is located on one side of the guide rail, and the output end of the linear drive device is fixedly connected to the lower mold structure.

[0013] In this embodiment, when using the pre-installed air conditioner pressing fixture, the corresponding upper and lower mold structures are selected according to the target product type. The upper mold structure is installed to the output end of the first drive device and firmly fixed by the upper mold positioning and locking mechanism. The lower mold structure is placed at the designated position on the base frame, and driven by the linear drive device of the second drive structure, the lower mold structure moves along the guide rail to the designated position, where it is precisely positioned and locked by the lower mold positioning and locking mechanism. The first drive device is activated, and the upper mold structure moves downward with the output end of the first drive device. The first and second contouring positions cooperate to perform high-pressure pressing on the product, completing the pressing process.

[0014] The introduction of the second drive structure automates the adjustment of the lower mold structure. In traditional tooling, the positioning of the lower mold structure usually requires manual adjustment, which is inefficient and prone to errors. This invention, however, uses a linear drive device to automatically move the lower mold structure along the guide rail to the designated position, reducing manual operation and improving positioning accuracy and efficiency. The linear drive device of the second drive structure can precisely control the movement distance and position of the lower mold structure, ensuring precise alignment between the lower and upper mold structures. Compared to manual adjustment, the linear drive device offers higher precision, effectively reducing product defects caused by inaccurate positioning and improving product quality.

[0015] In a preferred embodiment of this utility model, a positioning and measuring structure is provided on the upper mold structure. The positioning and measuring structure includes a connecting section and a free section. The free section is slidably disposed on the connecting section. The connecting section is inserted into the upper mold structure. The free section is vertically downward.

[0016] The lower mold structure is provided with positioning holes corresponding to the free section.

[0017] The positioning and measuring structure is used to achieve precise alignment between the upper and lower mold structures, thereby ensuring the pressing effect.

[0018] In this embodiment, when using the air conditioner pre-assembly pressing fixture, the corresponding upper and lower mold structures are selected according to the target product type. The upper mold structure is installed at the output end of the first drive device and firmly fixed by the upper mold positioning and locking mechanism. The lower mold structure is placed at the designated position on the base frame, and driven by the linear drive device of the second drive structure, the lower mold structure is moved along the guide rail to the designated position, and precisely positioned and locked by the lower mold positioning and locking mechanism.

[0019] After the upper mold structure is installed, the free section of the positioning and measuring structure is inserted into the positioning hole of the lower mold structure. The free section is slidably adjusted on the connecting section to ensure precise alignment between the upper and lower mold structures. Once the upper and lower mold structures are aligned, the first drive device can be activated. The upper mold structure moves downward with the output end of the first drive device. The first and second contouring positions cooperate to perform high-pressure pressing on the product, completing the pressing process.

[0020] The introduction of a positioning and measuring structure makes the alignment of the upper and lower mold structures more precise. The free section of the positioning and measuring structure matches the positioning holes of the lower mold structure, ensuring the consistency of the upper and lower mold positions during each pressing. This stable alignment method reduces pressing quality problems caused by mold position deviations and improves the stability of the production process.

[0021] In a preferred embodiment of this utility model, the lower mold structure includes a lower mold connecting plate, a pressing lower mold, and a wing screw. The lower mold connecting plate is slidably disposed on the guide rail, the pressing lower mold is disposed on the lower mold connecting plate, and the wing screw passes through the lower mold connecting plate and is threadedly connected to the pressing lower mold.

[0022] The lower clamping die is provided with the second contouring position; the wing screw includes a rod body and a connecting gripper, the connecting gripper being disposed at one end of the rod body.

[0023] The wing-shaped screw design makes the clamping lower die more securely fixed. The wing-shaped screw is threaded to the clamping lower die, and the clamping lower die can be quickly fixed and released by rotating the connecting gripper. The operation is simple and stable.

[0024] The lower mold connecting plate is slidably mounted on the guide rail, and in conjunction with a linear drive device, the position of the lower mold structure can be quickly adjusted. Compared to traditional fixed lower mold structures, this design makes the adjustment of the lower mold more flexible and can quickly adapt to the production needs of different products.

[0025] In a preferred embodiment of this invention, the upper mold structure includes an upper mold mounting plate and a pressing upper mold. The upper mold mounting plate is detachably mounted on the output end of the first driving device. The pressing upper mold is fixed on the upper mold mounting plate, and the bottom of the pressing upper mold is provided with the first contouring position.

[0026] In a preferred embodiment of this invention, the bottom of the upper mold mounting plate is provided with a slot, and the pressing upper mold is engaged in the slot.

[0027] The upper mold mounting plate is also provided with a locking component, which passes through the upper mold mounting plate and is fixedly connected to the pressing upper mold.

[0028] The assembly process of the upper mold is as follows:

[0029] Install the upper mold mounting plate onto the output end of the first drive device, ensuring a secure connection.

[0030] The upper clamping mold is snapped onto the upper mold mounting plate via a slot, and then fixedly connected to the upper clamping mold via a locking component that passes through the upper mold mounting plate, ensuring the stability and reliability of the upper clamping mold during installation.

[0031] The slot design of the upper mold mounting plate makes the installation of the clamping upper mold more convenient and stable. Through the slot engagement, the clamping upper mold can be quickly positioned and fixed on the mounting plate, reducing installation time. The locking mechanism further enhances the fixing effect of the clamping upper mold, ensuring that it will not shift during the pressing process, thus improving the stability and reliability of the pressing process.

[0032] In a preferred embodiment of this utility model, the base frame includes a base plate and an upright frame. The upright frame is fixed on the base plate, the lower mold structure is disposed on the base plate, and the first driving device is disposed on the upright frame and located above the lower mold structure.

[0033] The first drive unit is mounted on the upright frame, located above the lower mold structure. More preferably, the first drive unit is pneumatically driven, with the cylinder's output end connected to the upper mold mounting plate via a connector, enabling it to drive the upper mold structure to move up and down on the base frame. The cylinder's stroke and pressure can be adjusted according to different product requirements to meet the pressing requirements of products of different specifications.

[0034] In a preferred embodiment of this utility model, a plurality of the first driving devices are provided on the upright frame, and each of the first driving devices has an upper mold structure at its output end.

[0035] The base plate is provided with several lower mold structures corresponding to the upper mold structure.

[0036] In this embodiment, several upper mold structures are driven by several first driving devices, thereby enabling multiple products to be pressed simultaneously on the base frame, which can improve production efficiency.

[0037] In a preferred embodiment of this invention, the upper mold structure is provided with a first alignment device, and the lower mold structure is provided with a second alignment device, the second alignment device corresponding to the first alignment device.

[0038] In this embodiment, precise alignment of the upper and lower mold structures is achieved through electronic alignment. The first and second alignment devices can employ infrared alignment to achieve precise alignment between the two.

[0039] The beneficial effects of this utility model are as follows:

[0040] This utility model provides an air conditioner pre-assembly pressing fixture, which includes a base frame, on which a first driving device and an upper mold structure are mounted. The upper mold structure is detachably mounted on the output end of the first driving device. The first driving device drives the upper mold structure to move up and down on the base frame. A first contouring position is provided at the bottom of the upper mold structure. A detachable lower mold structure is also mounted on the base frame, and a second contouring position is provided on the lower mold structure, corresponding to the first contouring position. In use, according to the target product type, the corresponding upper and lower mold structures are selected. The upper mold structure is installed on the output end of the first driving device, and the lower mold structure is placed at the designated position on the base frame. The first driving device is activated, and the upper mold structure moves downward with the output end of the first driving device.

One set of base frame and drive device can match the molds of multiple machine models, eliminating the need to purchase a complete set of tooling for each machine model, reducing tooling purchase costs and avoiding waste of idle tooling. The detachable structure is compatible with multiple product specifications, and different production needs can be adapted simply by changing the corresponding mold. Attached Figure Description

Detailed Implementation

[0051] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0052] In the pre-assembly production of air conditioners, the adhesive bonding process for components such as air guides, handheld devices, panels, and control boards is crucial to product quality. In existing technologies, to ensure a tight bond under high pressure and avoid the risk of detachment, a common method is to use a contour mold combined with a cylinder for bonding: upper and lower contour molds are designed according to the product's appearance, and the upper mold is driven downwards by a cylinder to make high-pressure contact with the fixed lower mold to complete the bonding. In current production processes, the molds used in the bonding fixtures are directly fixed to the cylinders, requiring the entire fixture to be replaced when switching production models. This necessitates purchasing different fixtures for different models, increasing tooling costs. Furthermore, the inability to quickly switch between models results in low work efficiency and high labor intensity for employees.

[0053] Based on this, this application provides an air conditioner pre-installation pressing tool.

[0054] Example 1

[0055] like Figures 1-8 As shown, this embodiment provides an air conditioner pre-assembly pressing fixture, comprising:

[0056] A base frame 1 is provided with a first driving device 2 and an upper mold structure 3. The upper mold structure 3 is detachably provided at the output end of the first driving device 2. The first driving device 2 drives the upper mold structure 3 to move up and down on the base frame 1. A first contouring position 31 is provided at the bottom of the upper mold structure 3.

[0057] The base frame 1 is also provided with a detachable lower mold structure 4, and the lower mold structure 4 is provided with a second contouring position 41, which corresponds to the first contouring position 31.

[0058] Specifically, in practical applications, the base frame 1 serves as the fundamental framework of the entire tooling, supporting and securing other components. The base frame 1 is constructed of high-strength steel to ensure the stability and durability of the overall structure. Guide rails 51 and positioning devices are installed on the base frame 1 to guide the installation and movement of the upper mold structure 3 and the lower mold structure 4. The first drive device 2 is mounted on the base frame 1 and can be driven by a cylinder or a push rod motor. For example, the output end of the cylinder is connected to the upper mold structure 3 via a connector, enabling it to drive the upper mold structure 3 to move up and down on the base frame 1. The stroke and pressure of the cylinder can be adjusted according to different product requirements to meet the pressing requirements of products of different specifications.

[0059] When using this pre-installed air conditioner pressing fixture, select the corresponding upper mold structure 3 and lower mold structure 4 according to the target product type. Install the upper mold structure 3 onto the output end of the first drive device 2 and secure it firmly using the upper mold positioning and locking mechanism. Place the lower mold structure 4 in the designated position on the base frame 1 and accurately position and lock it using the lower mold positioning and locking mechanism. Start the first drive device 2, and the upper mold structure 3 moves downward with the output end of the first drive device 2. The first contouring position 31 and the second contouring position 41 cooperate to perform high-pressure pressing on the product, completing the pressing process.

[0060] Since both the upper mold structure 3 and the lower mold structure 4 are detachable, one set of base frame 1 and the first drive device 2 can be used to fit molds for multiple models. Enterprises no longer need to purchase a complete set of tooling for each model, significantly reducing tooling procurement costs. For example, for companies producing multiple air conditioner models, they would previously need a complete set of tooling for each model, which was very costly. However, by using this tooling, they only need to purchase one set of base frame 1 and drive device, and then replace the upper and lower molds as needed, significantly reducing costs.

[0061] The detachable structure makes mold changes more convenient and faster. When switching between production of different product models, there is no need to change the entire tooling; only the corresponding upper and lower molds need to be replaced, which greatly shortens turnaround time and improves production efficiency.

[0062] Example 2

[0063] This embodiment is an improvement on embodiment 1.

[0064] like Figures 1-8 As shown, in this embodiment, a second driving structure 5 is provided on the base frame 1. The second driving structure 5 includes a guide rail 51 and a linear driving device 52. The guide rail 51 is located below the first driving device 2, and the lower mold structure 4 is slidably disposed on the guide rail 51.

[0065] The linear drive device 52 is disposed on one side of the guide rail 51, and the output end of the linear drive device 52 is fixedly connected to the lower mold structure 4.

[0066] In this embodiment, a second driving structure 5 is provided on the base frame 1 for automatically adjusting the position of the lower mold structure 4. The second driving structure 5 includes a guide rail 51 and a linear driving device 52. The guide rail 51 is located below the first driving device 2, and the lower mold structure 4 is slidably mounted on the guide rail 51 via a slider, enabling it to move horizontally along the guide rail 51. The linear driving device 52 is located on one side of the guide rail 51, and its output end is fixedly connected to the lower mold structure 4 via a connector, enabling it to drive the lower mold structure 4 to move horizontally along the guide rail 51, achieving automatic positioning and adjustment. More preferably, two guide rails 51 are provided, and the second driving structure 5 is located between the two guide rails 51. The lower mold structure 4 is fixed on the two guide rails 51, and the second driving structure 5 drives the lower mold structure 4 to move on the guide rails 51, ensuring the stability of the movement of the lower mold structure 4.

[0067] When using this pre-installed air conditioner pressing fixture, select the corresponding upper mold structure 3 and lower mold structure 4 according to the target product type. Install the upper mold structure 3 onto the output end of the first drive device 2 and secure it firmly using the upper mold positioning and locking mechanism. Place the lower mold structure 4 at the designated position on the base frame 1, and drive it along the guide rail 51 to the designated position using the linear drive device 52 of the second drive structure 5. Precisely position and lock it using the lower mold positioning and locking mechanism. Start the first drive device 2, and the upper mold structure 3 moves downward with the output end of the first drive device 2. The first contouring position 31 and the second contouring position 41 cooperate to perform high-pressure pressing on the product, completing the pressing process.

[0068] The introduction of the second drive structure 5 automates the adjustment of the lower mold structure 4. In traditional tooling, the positioning of the lower mold structure 4 typically requires manual adjustment, which is inefficient and prone to errors. This invention, however, uses a linear drive device 52 to automatically drive the lower mold structure 4 along the guide rail 51 to the designated position, reducing manual operation and improving positioning accuracy and efficiency. The linear drive device 52 of the second drive structure 5 can precisely control the movement distance and position of the lower mold structure 4, ensuring precise alignment between the lower mold structure 4 and the upper mold structure 3. Compared to manual adjustment, the linear drive device 52 offers higher precision, effectively reducing product defects caused by inaccurate positioning and improving product quality.

[0069] Example 3

[0070] This embodiment is an improvement on embodiment 2.

[0071] like Figures 1-8 As shown, in this embodiment, the upper mold structure 3 is provided with a positioning and measuring structure 6. The positioning and measuring structure 6 includes a connecting section 61 and a free section 62. The free section 62 is slidably disposed on the connecting section 61. The connecting section 61 is inserted into the upper mold structure 3, and the free section 62 is disposed vertically downward.

[0072] The lower mold structure 4 is provided with positioning holes 43 corresponding to the free section 62.

[0073] The positioning and measuring structure 6 is used to achieve precise alignment between the upper mold structure 3 and the lower mold structure 4, thereby ensuring the pressing effect.

[0074] In this embodiment, when using the air conditioner pre-assembly pressing fixture, the corresponding upper mold structure 3 and lower mold structure 4 are selected according to the target product type. The upper mold structure 3 is installed to the output end of the first drive device 2 and firmly fixed by the upper mold positioning and locking mechanism. The lower mold structure 4 is placed at the designated position on the base frame 1, and the lower mold structure 4 is driven to move along the guide rail 51 to the designated position by the linear drive device 52 of the second drive structure 5, and is precisely positioned and locked by the lower mold positioning and locking mechanism.

[0075] After the upper mold structure 3 is installed, the free segment 62 of the positioning and measuring structure 6 is inserted into the positioning hole 43 of the lower mold structure 4. By sliding the free segment 62 on the connecting segment 61, the precise alignment of the upper mold structure 3 and the lower mold structure 4 is ensured. After the upper mold structure 3 and the lower mold structure 4 are aligned, the first drive device 2 can be started. The upper mold structure 3 moves downward with the output end of the first drive device 2. The first contouring position 31 and the second contouring position 41 cooperate to perform high-pressure pressing on the product, completing the pressing process.

[0076] More specifically, the positioning and measuring structure 6 of this application adopts a telescopic sleeve design. For example, the free section 62 is a small-diameter section and the free section 62 is a large-diameter section. The small-diameter section is fixed on the upper mold structure 3, and the large-diameter section is vertically downward under the action of gravity. During the positioning process, when the second drive structure 5 drives the lower mold structure 4 to enter below the positioning and measuring structure 6, and the free section 62 falls into the positioning hole 43 of the lower mold structure 4, the lower mold structure 4 and the upper mold structure 3 are aligned, and at this time the second drive structure 5 stops operating.

[0077] The introduction of the positioning and measuring structure 6 makes the alignment of the upper mold structure 3 and the lower mold structure 4 more precise. The free section 62 of the positioning and measuring structure 6 cooperates with the positioning hole 43 of the lower mold structure 4 to ensure the consistency of the position of the upper and lower molds during each pressing. This stable alignment method reduces pressing quality problems caused by mold position deviations and improves the stability of the production process.

[0078] Example 4

[0079] This embodiment is an improvement on embodiment 1.

[0080] like Figures 1-8As shown, in this embodiment, the lower mold structure 4 includes a lower mold connecting plate 45, a pressing lower mold 42, and a wing screw 44. The lower mold connecting plate 45 is slidably disposed on the guide rail 51, the pressing lower mold 42 is disposed on the lower mold connecting plate 45, and the wing screw 44 passes through the lower mold connecting plate 45 and is threadedly connected to the pressing lower mold 42.

[0081] The lower clamping die 42 is provided with the second contouring position 41; the wing screw 44 includes a rod body 441 and a connecting gripper 442, the connecting gripper 442 being disposed at one end of the rod body 441.

[0082] The installation method of the lower mold structure 4 is as follows: Place the lower mold connecting pressure plate 45 on the guide rail 51 to ensure that it can move smoothly along the guide rail 51.

[0083] The lower clamping die 42 is placed on the lower die connecting plate 45 and fixed by the wing screw 44. The operator rotates the connecting gripper 442 of the wing screw 44 to make the rod 441 of the wing screw 44 threadedly connected to the lower clamping die 42, thus achieving a firm fixation of the lower clamping die 42.

[0084] The design of the wing-shaped screw 44 makes the clamping lower die 42 more securely fixed. The rod body 441 of the wing-shaped screw 44 is threadedly connected to the clamping lower die 42. By rotating the connecting gripper 442, the clamping lower die 42 can be quickly fixed and released, making the operation simple and stable.

[0085] The lower mold connecting pressure plate 45 is slidably mounted on the guide rail 51, and in conjunction with the linear drive device 52, the position of the lower mold structure 4 can be quickly adjusted. Compared with the traditional fixed lower mold structure 4, this design makes the adjustment of the lower mold more flexible and can quickly adapt to the production needs of different products.

[0086] Example 5

[0087] This embodiment is an improvement on embodiment 1.

[0088] like Figures 1-8 As shown, in this embodiment, the upper mold structure 3 includes an upper mold mounting plate 32 and a pressing upper mold 33. The upper mold mounting plate 32 is detachably disposed at the output end of the first driving device 2. The pressing upper mold 33 is fixed on the upper mold mounting plate 32. The bottom of the pressing upper mold 33 is provided with the first contouring position 31.

[0089] In this embodiment, the bottom of the upper mold mounting plate 32 is provided with a slot 321, and the pressing upper mold 33 is engaged in the slot 321;

[0090] The upper mold mounting plate 32 is also provided with a locking member 34, which penetrates the upper mold mounting plate 32 and is fixedly connected to the pressing upper mold 33. The assembly process of the upper mold is as follows: The upper mold mounting plate 32 is installed on the output end of the first drive device 2, ensuring that the connection is firm. The pressing upper mold 33 is snapped onto the upper mold mounting plate 32 through the slot 321, and then fixedly connected to the pressing upper mold 33 through the locking member 34, ensuring the stability and reliability of the pressing upper mold 33 during the installation process. The slot 321 design of the upper mold mounting plate 32 makes the installation of the pressing upper mold 33 more convenient and stable. Through the snap-fit ​​method of the slot 321, the pressing upper mold 33 can be quickly positioned and fixed on the upper mold mounting plate 32, reducing the installation time. The design of the locking member 34 further enhances the fixing effect of the pressing upper mold 33, ensuring that the pressing upper mold 33 will not shift during the pressing process, improving the stability and reliability of the pressing.

[0091] Example 6

[0092] This embodiment is an improvement on embodiment 1.

[0093] like Figures 1-8 As shown, in this embodiment, the base frame 1 includes a base plate 11 and a vertical frame 12. The vertical frame 12 is fixed on the base plate 11, the lower mold structure 4 is disposed on the base plate 11, the first driving device 2 is disposed on the vertical frame 12, and the first driving device 2 is located above the lower mold structure 4.

[0094] The first drive device 2 is mounted on the upright frame 12, located above the lower mold structure 4. More preferably, the first drive device 2 is pneumatically driven, with the cylinder output connected to the upper mold mounting plate 32 via a connector, enabling it to drive the upper mold structure 3 to move up and down on the base frame 1. The stroke and pressure of the cylinder can be adjusted according to different product requirements to meet the pressing requirements of products of different specifications.

[0095] More preferably, the support frame 12 is provided with a plurality of the first driving devices 2, and each of the first driving devices 2 is provided with an upper mold structure 3 at its output end;

[0096] The base plate 11 is provided with a plurality of lower mold structures 4 corresponding to the upper mold structure 3.

[0097] In this embodiment, several first driving devices 2 drive several upper mold structures 3, thereby enabling multiple products to be pressed simultaneously on the base frame 1, which can improve production efficiency.

[0098] Example 7

[0099] This embodiment is an improvement on embodiment 1.

[0100] like Figures 1-8 As shown, in this embodiment, the upper mold structure 3 is provided with a first alignment device, and the lower mold structure 4 is provided with a second alignment device, the second alignment device corresponding to the first alignment device.

[0101] In this embodiment, precise alignment of the upper mold structure 3 and the lower mold structure 4 is achieved through electronic alignment. The first alignment device and the second alignment device can use infrared alignment to achieve precise alignment between the two.

[0102] In this embodiment, precise alignment of the upper mold structure 3 and the lower mold structure 4 is achieved through an infrared alignment device. The infrared alignment sensor can accurately detect positional deviations and achieve precise alignment through automated adjustments, reducing errors from manual alignment and improving alignment accuracy. Compared to alignment via the positioning and measuring structure 6, this alignment method has a higher degree of automation.

[0103] Example 8

[0104] This embodiment provides a mold-changing method for an air conditioner pre-assembly pressing tool, which is implemented based on the air conditioner pre-assembly pressing tool described above.

[0105] The specific steps of this method are as follows:

[0106] Select the appropriate clamping upper mold 33 according to the target product type and snap it into the slot 321 of the upper mold mounting plate 32.

[0107] The upper mold 33 is securely fixed to the upper mold mounting plate 32 by the locking element 34, ensuring that it will not shift during the pressing process.

[0108] Select the appropriate clamping lower mold 42 according to the target product type and place it on the lower mold connecting pressure plate 45.

[0109] The lower die 42 is securely fixed to the lower die connecting plate 45 by the wing screw 44, ensuring that it will not shift during the pressing process.

[0110] The linear drive device 52 of the second drive structure 5 is activated, driving the lower mold connecting pressure plate 45 to move along the guide rail 51 to the designated position. The positioning and measuring structure 6 ensures the precise alignment of the lower mold structure 4 and the upper mold structure 3.

[0111] After the entire device is assembled, the first drive unit 2 is started to run the upper mold structure 3 without load, checking the fit between the upper mold structure 3 and the lower mold structure 4 to ensure there are no abnormalities during the pressing process. The cylinder stroke and pressure are adjusted according to product requirements to ensure the pressing effect meets process requirements. A small amount of product is placed in for test pressing to check product quality and ensure a good pressing effect.

[0112] After debugging, formal production began, and the pressing operation was carried out according to the process requirements.

[0113] This method utilizes a detachable upper and lower mold design, allowing the tooling to be compatible with various product specifications. Companies can quickly change molds according to different production needs, eliminating the need to purchase multiple sets of tooling and reducing equipment investment costs.

[0114] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0115] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0116] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
