[0028] As Figures 1 - 5 shown, an embodiment of the present utility model provides an exhaust structure for an injection mold of an automotive air-conditioning accessory, including a mold body 1. An exhaust hole is provided at the top of the mold body 1, and the position of the exhaust hole corresponds to the position of the circular hole at the bottom of the exhaust chamber 21. It further includes: an exhaust assembly 2. The exhaust assembly 2 includes an exhaust chamber 21 fixed at the exhaust hole at the top of the mold body 1. The exhaust chamber 21 is in communication with the mold body 1. A circular hole is provided at the bottom of the exhaust chamber 21, and the size of the circular hole is the same as the size of the exhaust hole of the mold body 1. A push rod 23 penetrates through the end of the exhaust chamber 21. A push block 22 is fixed at the end of the push rod 23. An inclined surface is provided at the end of the push block 22. The push block 22 is slidably connected in the exhaust chamber 21. A flip door 26 is rotatably connected to the end of the exhaust chamber 21 away from the push block 22 through a rotating shaft. The inclined surface position of the push block 22 is located above the exhaust hole and the circular hole, and the inclined surface can guide the material at the splashing position, so that the material is prevented from being pushed and squeezed at the air outlet position of the mold body 1, and the circular hole and the exhaust hole are prevented from being blocked by the material.

[0029] As Figures 1 - 4 shown, in this embodiment, a handle 24 is fixed at the end of the push rod 23 away from the push block 22. The handle 24 is concentric with the push rod 23. The handle 24 increases the contact area with the hand, and when the push rod 23 is pushed through the handle 24, the hand feels more comfortable.

[0030] As Figures 1 - 4As shown, in this embodiment, a spring 25 is sleeved on the surface of the push rod 23. Both ends of the spring 25 are fixedly connected to the surface of the exhaust chamber 21 and the surface of the handle 24 respectively. After the handle 24 moves towards the exhaust chamber 21, the spring 25 is compressed. When the handle 24 is released, the spring 25 will rebound, and the spring 25 will drive the handle 24 and the like to reset. There is no need to manually pull the handle 24 and the like to reset, which is more convenient and labor-saving.

[0031] As Figures 1 - 2 shown, in this embodiment, two exhaust chambers 21 are provided in total, and the two exhaust chambers 21 are symmetrically arranged about the middle of the mold body 1. The number of exhaust chambers 21 corresponds to the number of air outlet holes.

[0032] As Figures 1 - 5 shown, in this embodiment, a driving component 3 is arranged on the surface of the exhaust chamber 21. The driving component 3 includes a driving rod 31. A through groove is formed on the side of the exhaust chamber 21. The driving rod 31 is slidably connected in the through groove. The side surface of the driving rod 31 is fixedly connected to the side surface of the push block 22. A rack 32 is fixed on the side surface of the driving rod 31. A gear 33 is fixed at the end of the rotating shaft of the flip door 26. The gear 33 is located outside the exhaust chamber 21. The push block 22 can move to make the driving rod 31 drive the rack 32 to engage with the gear 33 and drive the gear 33 to rotate. When the gear 33 rotates, it drives the flip door 26 to rotate synchronously through the rotating shaft. After the rack 32 drives the gear 33 to rotate, the gear 33 will drive the flip door 26 to rotate 90 degrees through the rotating shaft. The surface of the gear 33 is movably connected to the surface of the exhaust chamber 21.

[0033] As Figure 4 and Figure 5 shown, in this embodiment, a guide rod 34 is slidably connected in the guide hole of the driving rod 31. The guide rod 34 will guide the driving rod 31 to prevent the driving rod 31 from shifting during movement, making the movement of the driving rod 31 more stable. The end of the guide rod 34 is fixed to the inner wall of the through groove of the exhaust chamber 21.

[0034] As Figure 4 and Figure 5 shown, in this embodiment, the guide rod 34 and the push rod 23 are arranged in parallel. The moving direction of the push rod 23 is the moving direction of the driving rod 31 on the surface of the guide rod 34. After the two are arranged in parallel, the guide rod 34 can play a stable guiding role for the driving rod 31.

[0035] Working principle: When the mold body 1 is in use, materials will splash outwards from the air outlet of the mold body 1. The splashed materials hit the inclined surface of the push block 22, and the inclined surface of the push block 22 guides the materials, and the materials will splash into the exhaust chamber 21 far away from the air outlet. After using for a period of time, the exhaust chamber 21 needs to be cleaned. When cleaning, hold the hand on the surface of the handle 24 and push the handle 24 towards the position of the exhaust chamber 21. The handle 24 drives the push rod 23 to move, and the push rod 23 drives the push block 22 to move. When the push block 22 slides in the exhaust chamber 21, the push block 22 will push the materials in the exhaust chamber 21 outwards uniformly. And when the push block 22 moves, the push block 22 drives the drive rod 31 to move, and the drive rod 31 drives the rack 32 to move. When the push block 22 approaches the flip door 26, the rack 32 also approaches the gear 33, and the rack 32 drives the gear 33 to rotate 90 degrees. The gear 33 drives the rotating shaft to drive the flip door 26 to rotate 90 degrees. When the rack 32 drives the gear 33 to rotate 90 degrees, the push block 22 will push the materials out of the exhaust chamber 21 at this time. After cleaning the materials at the outlet position of the exhaust chamber 21, release the handle 24, and the spring 25 will drive the handle 24 away from the exhaust chamber 21. The handle 24 will drive the push rod 23 to move in the reverse direction, and the push rod 23 will drive the push block 22 to move in the reverse direction until the push block 22 is reset. And when the push block 22 moves in the reverse direction, the push block 22 drives the drive rod 31 to move in the reverse direction, and the drive rod 31 drives the rack 32 to move in the reverse direction, and the rack 32 drives the gear 33 to rotate in the reverse direction, and the gear 33 drives the flip door 26 to rotate in the reverse direction and reset. Then the mold body 1 can continue to be used.

[0036] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
