Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically a stretching mold for processing air conditioner chassis. Background Technology
[0002] The air conditioner chassis is an important component of air conditioning equipment. It not only supports and fixes various internal components of the air conditioner (such as compressor, condenser, evaporator, etc.), but also plays a key role in the structural stability and heat dissipation performance of the entire air conditioner. The stretching die used in the processing of the air conditioner chassis is a tool specially used to manufacture the air conditioner shell or chassis. Through the stretching process, metal sheets (such as steel plates, aluminum plates, etc.) are shaped into the required shape.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN214814192U) discloses a stretching die for processing air conditioner chassis. The die includes a lower die base with a concave die on its inner wall at the center. An upper die base is positioned directly above the lower die base, with a convex die on its inner wall at the center. Pressure plate cavities are fixedly installed on the outer walls of both sides of the bottom end of the upper die base. Automatic push rods are installed inside each pair of pressure plate cavities. Vertical rods are fixedly connected to the outer walls of the bottom ends of each pair of automatic push rods. Wedge blocks are fixedly connected to the outer walls of the bottom ends of each pair of vertical rods. By incorporating automatic push rods, pressure plate cavities, wedge blocks, and pressure grooves, the edge shape of the air conditioner chassis is prevented from being damaged due to excessive pressure, and wrinkles are prevented from appearing due to weak pressure. This avoids situations where the pressure is too tight or too loose during the pressure process, ensuring a high pass rate for the air conditioner chassis and improving production efficiency and pressure stability.
[0004] Although the aforementioned patent avoids excessive tightness or looseness during edge pressing by setting up automatic push rods, pressure plate cavities, wedge blocks, and edge pressing grooves, thus ensuring the pass rate of air conditioner chassis and improving its production efficiency and edge pressing stability, it lacks a guiding function during edge pressing and stamping. The lack of guidance can lead to positional deviations during mold assembly. Deviations in mold fit may cause defects such as wrinkles, scratches, and cracks during stretching, affecting the product's appearance quality.
[0005] Therefore, this utility model provides a stretching die for processing air conditioner chassis to solve the above problems. Utility Model Content

[0008] The guiding mechanism includes a vertical plate, the side of which is fixedly connected to the inner wall of the support rod.

[0013] As a preferred technical solution of this application, a stamping block is fixedly connected to the bottom end of the frame plate, and one side of the stamping block is fixedly connected to the side of the connecting rod.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. Through the set guide mechanism, the upper and lower dies can be precisely aligned to avoid deviation and ensure that the dimensions of the stretched finished product are consistent.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a stretching die for processing air conditioner chassis, such as... Figures 1-5 As shown, the stretching die for processing an air conditioner chassis includes a lower die 1, with support rods 2 fixedly connected to all four sides of the upper surface of the lower die 1, an upper die 3 fixedly connected to one end of the support rods 2, a stamping mechanism fixedly connected to the middle of the upper die 3, and a guide mechanism fixedly connected to the inner side wall of the support rods 2.
[0026] The guiding mechanism includes a vertical plate 4, the side of which is fixedly connected to the inner wall of the support rod 2. A groove is provided on the surface of the vertical plate 4, and a slider 5 is slidably connected inside the groove. A buffer spring 6 is fixedly connected to the bottom of the slider 5, and a connecting rod 7 is fixedly connected to one end of the slider 5. The guiding mechanism can guide the precise alignment of the upper and lower molds, avoid deviations, ensure consistent dimensions of the stretched finished products, reduce product deformation, wrinkles and other defects, improve the consistency and pass rate of finished products, ensure correct mold alignment, reduce uneven loads and impacts, and delay mold fatigue and wear.
[0027] The stamping mechanism includes an electric push rod 8, the outer surface of which is fixedly connected to the middle of the upper die 3. One end of the electric push rod 8 is fixedly connected to a frame plate 9. Adding a spring to the stamping mechanism can effectively absorb the impact load generated during stamping, reduce the stress on the die and stamping equipment, slow down the impact load, reduce the cracks, fatigue and damage of the die, and improve the service life of the die.
[0028] A buffer spring 10 is fixedly connected to the middle of the upper surface of the frame plate 9. One end of the buffer spring 10 is fixedly connected to the middle of the bottom of the upper mold 3. The electric push rod 8 drives the frame plate 9 and the stamping block 16 to press up and down. When the stamping block 16 presses the material, the buffer spring 10 in the middle of the upper surface of the frame plate 9 provides initial buffering to avoid excessive pressing in the middle of the stamping block 16, which would affect the stamping effect.
[0029] Limiting rods 11 are fixedly connected to both sides of the upper surface of the frame plate 9. A C-buffered spring 12 is fixedly connected to the outer surface of the bottom of the limiting rod 11. The C-buffered spring 12 provides a secondary buffering effect for the frame plate 9.
[0030] A sleeve plate 13 is inserted into the outer surface of the limiting rod 11. Support rods 14 are fixedly connected to both sides of the bottom of the sleeve plate 13. One end of the support rod 14 is fixedly connected to one side of the upper surface of the upper mold 3. A D buffer spring 15 is fixedly connected to the bottom of the sleeve plate 13. The limiting rod 11 plays a limiting role to prevent the C buffer spring 12 and the D buffer spring 15 from being displaced during extrusion.
[0031] A stamping block 16 is fixedly connected to the bottom of the frame plate 9. One side of the stamping block 16 is fixedly connected to the side of the connecting rod 7. The stamping block 16 is divided into three parts, which can apply pressure to the material evenly. Combined with the B buffer spring 10, C buffer spring 12 and D buffer spring 15, it can play a buffering effect during stamping and reduce damage to the material.
[0032] Specifically, the material to be processed is placed on the lower mold 1, and the electric push rod 8 on the upper mold 3 is activated. The electric push rod 8 drives the frame plate 9 and the stamping block 16 to press up and down. When the stamping block 16 presses the material, it is initially buffered by the B buffer spring 10 in the middle of the upper surface of the frame plate 9 to avoid excessive pressing in the middle of the stamping block 16, which would affect the stamping effect. Subsequently, the limiting rods 11, C buffer spring 12 and D buffer spring 15 on both sides of the upper surface of the frame plate 9 press the upper mold 3 with the C buffer spring 12 and the D buffer spring 15 press the sleeve plate 13, so that the frame plate 9... The stamping blocks 16 on both sides of the bottom act as a buffer during stamping. Subsequently, during stamping, there are connecting rods 7 and sliders 5 on both sides of the frame plate 9. The sliders 5 slide inside the vertical plate 4. When sliding, they are squeezed up and down by buffer spring A 6, which can buffer the squeezing effect while guiding. The guiding mechanism can guide the precise alignment of the upper and lower dies, avoid deviation, and ensure that the dimensions of the stretched finished product are consistent. Precise die assembly reduces defects such as product deformation and wrinkles, and improves the consistency and pass rate of finished products. The guiding mechanism ensures that the die is correctly aligned, reduces uneven load and impact, and delays die fatigue and wear.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
