Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an integrated injection molding mold for an air conditioner front panel. Background Technology

[0002] The front panel of an air conditioner is a component installed in front of the indoor unit of the air conditioner. It not only serves to decorate the appearance of the air conditioner, but also protects the internal components. At the same time, its surface usually has structures such as air outlets and control panels, which are closely related to user interaction.

[0003] One-piece injection molding mold is a type of mold used to mold plastic raw materials into a specific shape in one step through injection molding. Using one-piece injection molding mold to produce air conditioner front panels can ensure the integrity and structural strength of the panel, avoid gaps and assembly problems caused by splicing multiple parts, improve production efficiency and reduce production costs.

[0004] The existing one-piece injection molding mold for air conditioner front panel has the following shortcomings:

[0005] Existing mold cooling structures are simple, relying solely on the mold's own heat dissipation or a small number of cooling channels, which cannot quickly remove the large amount of heat generated during injection molding. This results in long mold cooling times, which in turn affects the molding efficiency of the air conditioner front panel. For example, during continuous production, the mold remains at a high temperature for an extended period, and the cooling rate cannot keep up with the injection speed, forcing a longer molding cycle for each batch of products. At the same time, the demolding structure of existing devices mostly uses ordinary ejector pins. When ejecting the air conditioner front panel, the small contact area between the ejector pin and the panel easily leaves ejector pin marks on the panel surface, and may even cause local damage to the panel. Moreover, ordinary ejector pins can only eject from a single position, and cannot provide stable support for larger panels, which may lead to problems such as the panel falling or deforming during the ejection process.

[0015] Preferably, the output shafts at both ends of the dual-head motor are fixedly connected to transmission screws, and the outer surface of the transmission screws is threaded with a threaded sliding plate.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a technical solution: it includes a lower mold base 1, with lifting slide columns 2 fixedly connected to the four corners of the top of the lower mold base 1, an upper mold base 3 fixedly connected to the top of the four lifting slide columns 2, a lower template 4 fixedly connected to the top centerline of the lower mold base 1, an upper template 5 fixedly connected to the bottom center of the upper mold base 3, a cooling assembly 6 provided on the rear side of the lower template 4, a pushing assembly 7 provided on the bottom of the lower template 4, connecting grooves 41 opened on the upper left and right sides of the lower template 4, and several through slots 42 opened on the opposite sides of the two connecting grooves 41, the cooling assembly 6 includes two connecting plates 61, the connecting plates 61 are fixedly connected to the inner wall of the connecting grooves 41, a circulation pipe 62 is fixedly connected to the rear end of the two connecting plates 61, the front end of the circulation pipe 62 extends into the interior of the connecting plates 61 and several cooling pipes 63 are fixedly connected to its outer surface, a connecting cover 64 is fixedly connected to the rear end of the connecting plates 61, and the cooling pipes 63 are fixedly connected to the inner wall of the through slots 42, the lower template 4... Several heat dissipation fins 66 are fixedly connected to the rear side of the outer surface, and the heat dissipation fins 66 penetrate to the inner side of the connecting cover 64. Several heat dissipation fins 67 are fixedly connected in a ring array to the inner surface of the circulation pipe 62, and the heat dissipation fins 67 penetrate to the inner side of the connecting cover 64. A flow guiding assembly 68 is rotatably connected to the middle of the circulation pipe 62. The flow guiding assembly 68 includes a rotating ring 681, which is rotatably connected to the middle of the circulation pipe 62. The outer surface of the rotating ring 681 is fixedly connected to... The device includes a guide fan 682, a guide fan 683 fixedly connected to the inner surface of a rotating ring 681, dustproof nets 65 fixedly connected to both sides of the inner surface of a connecting cover 64, a belt drive assembly 69 provided on the front side of the guide assembly 68, the belt drive assembly 69 including two pulleys and a drive belt, the right side of the rotating ring 681 fixedly connected to the front pulley, and a drive motor 610 fixedly connected to the middle of the rear side of the inner wall of the connecting plate 61, the output shaft of the drive motor 610 fixedly connected to the rear pulley;

[0031] The overall effect of Embodiment 1 is as follows: the drive motor 610 starts and drives the rotating ring 681 to rotate through the belt drive assembly 69. When the rotating ring 681 rotates, the guide fan 682 on its outer surface rotates, accelerating the airflow inside the connecting cover 64 and dissipating internal heat. At the same time, the guide fan 683 on the inner surface of the rotating ring 681 causes the coolant to circulate in the circulation pipe 62 and the cooling pipe 63. The heat generated by the lower mold plate 4 is conducted to the inside of the connecting cover 64 through the heat dissipation fin 1 66 and absorbed by the coolant. The coolant then transfers the heat to the heat dissipation fin 2 67 and dissipates it into the connecting cover 64, and is finally discharged by the guide fan 682. This achieves efficient heat dissipation of the mold and speeds up the molding speed of the air conditioner front panel. The dustproof net 65 can prevent external dust and other impurities from entering the connecting cover 64 and affecting the heat dissipation effect and service life of the cooling assembly.

[0032] Example 2: As Figure 2 and Figure 5 As shown, this utility model provides a technical solution: a mold cavity 43 is provided at the top of the connecting slide 41, and grooves 44 are provided on both the left and right sides of the lower surface of the inner wall of the mold cavity 43. A sliding groove 45 is provided at the bottom of the lower template 4. The pushing assembly 7 includes a U-shaped connecting frame 71, which is fixedly connected to the middle of the upper surface of the sliding groove 45. A double-headed motor 72 is fixedly connected to the middle of the inner side of the U-shaped connecting frame 71. A transmission screw 73 is fixedly connected to the output shafts at both the front and rear ends of the double-headed motor 72. A threaded sliding plate 74 is threadedly connected to the outer surface of the transmission screw 73. The left and right sides of the threaded sliding plate 74 are... The guide post 75 is slidably connected to the front and back. The guide post 75 is fixedly connected to the inner surface of the U-shaped connecting frame 71. Pull rods 76 are movably hinged to the bottom left and right sides of the threaded slide plate 74. A connecting rod 77 is rotatably connected to the bottom end of the two pull rods 76. A sliding top plate 78 is fixedly connected to the left and right ends of the two connecting rods 77. Two push plates 79 are fixedly connected to the top of the sliding top plate 78. The top ends of the two push plates 79 penetrate into the interior of the groove 44 and are fixedly connected to the ejector plate 710. The upper surface of the ejector plate 710 is in contact with the lower surface of the inner surface of the mold cavity 43.

[0033] The effect achieved by the entire embodiment 2 is as follows: After the air conditioner front panel is injection molded, the dual-head motor 72 starts, and the output shafts at its front and rear ends drive the transmission screw 73 to rotate synchronously. Since the threaded slide plate 74 is threadedly connected to the transmission screw 73, and there are guide posts 75 on both sides that restrict it to slide only back and forth, when the transmission screw 73 rotates, the threaded slide plate 74 slides back and forth along the direction of the guide posts 75. During the sliding process of the threaded slide plate 74, the pull rod 76 hinged at its bottom drives the connecting rod 77 to move upward. The connecting rod 77 then pushes the sliding top plate 78 to rise. The sliding top plate 78 pushes the ejector plate 710 to move upward through the push plate 79, and smoothly ejects the air conditioner front panel formed in the mold cavity 43. Compared with the traditional ejector pin, the ejector plate 710 has a larger contact area with the panel, and the force is more dispersed during ejection, which can avoid leaving marks or causing local damage on the panel surface. At the same time, it supports the panel from multiple positions, effectively preventing the panel from falling or deforming during the ejection process.

[0034] The working principle of the entire equipment is as follows: In the injection molding preparation stage, the operator first adjusts the upper mold base 3 and the lower mold base 1 to the appropriate initial position through the lifting slide column 2 to prepare for mold closing. When injection begins, the upper mold base 3 moves downward along the lifting slide column 2 under the drive of external power until the upper mold plate 5 and the lower mold plate 4 are tightly fitted, completing the mold closing action. At this time, the mold cavity 43 formed by the upper mold plate 5 and the lower mold plate 4 is closed. Then, the injection molding equipment injects the high-temperature molten plastic raw material into the mold cavity 43 at high speed through the preset gate. The plastic raw material flows in the mold cavity and fills every corner, gradually forming the shape of the air conditioner front panel.

[0035] As the plastic raw material is injected into the mold cavity 43, the cooling component 6 immediately starts working, and the drive motor 610 is powered on and runs. Its output shaft drives the rear pulley to rotate, and through the transmission belt in the belt drive component 69, the power is transmitted to the front pulley, which in turn drives the rotating ring 681 to rotate at high speed in the middle of the circulation pipe 62. The guide fan 682 on the outer surface of the rotating ring 681 rotates accordingly, accelerating the exhaust speed of the internal hot air. At the same time, the guide fan 683 on the inner surface of the rotating ring 681 causes the coolant to circulate in the circulation pipe 62 and the cooling pipe 63. The lower mold plate 4 absorbs a lot of heat during the injection molding process. Part of this heat is directly conducted to the inside of the connecting cover 64 through the heat dissipation fin 1 66, and the other part is absorbed by the coolant. After absorbing the heat, the coolant transfers the heat to the heat dissipation fin 2 67 during the circulation process. The heat dissipation fin 2 67 then dissipates the heat into the connecting cover 64 and is finally discharged by the guide fan 682. This cycle achieves efficient heat dissipation of the mold and greatly shortens the cooling and molding time of the air conditioner front panel.

[0036] After the air conditioner front panel cools and solidifies in the mold cavity 43, it enters the demolding stage. At this time, the push assembly 7 starts working, the dual-head motor 72 is powered on and starts, and its front and rear output shafts rotate synchronously, driving the transmission screw 73 fixed on the shaft to rotate. When the transmission screw 73 rotates, the threaded slide plate 74 slides back and forth along the direction of the guide post 75. As the threaded slide plate 74 slides, the pull rods 76 that are movably hinged on the left and right sides of its bottom also move. The bottom end of the pull rod 76 drives the connecting rod 77 to move upward. The rise of the connecting rod 77 pushes the sliding top plate 78 connected to it to rise synchronously. The sliding top plate 78 pushes the ejector plate 710 upward through the two push plates 79 at the top. The ejector plate 710 gradually and smoothly ejects the air conditioner front panel formed in the mold cavity 43, completing the entire injection molding and demolding process.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
