Description

Technical Field

[0001] The present invention relates to the technical field of automotive part forming, and particularly to a forming mechanism for automotive air outlet blades. Background Art

[0002] The blades inside the automotive air conditioner outlet are the channel control part for delivering the air conditioner inside the vehicle to the passenger compartment, used to control the wind direction and air volume when the air conditioner blows, providing a comfortable riding environment for the passengers inside the vehicle. Secondly, to ensure the air volume of the air conditioner outlet, a relatively large air outlet is required. Most of them adopt the method of synchronously moving multiple blades through connecting rods to open or close the air outlet by moving the blades.

[0003] Due to the continuous impact of the air flow generated by the air conditioner on the blades, the blades need a certain strength and the material hardness is relatively high, resulting in several gaps formed between multiple blades. When the blades are closed, the air flow can still enter the vehicle body through the several gaps, causing air leakage. At the same time, the blades collide with the housing when moving, generating noise. To improve the above problems, various factories and enterprises adopt technical means such as filling with sponge, changing the blade shape, and using soft rubber to wrap the blades.

[0004] However, using soft rubber to wrap the blades requires secondary molding in the mold to make the soft rubber wrap part of the blades, reducing or eliminating the gaps or reducing the sound of the blades colliding with the housing. However, the secondary molding of the mold requires more processes to process the blades, which is time-consuming and laborious, and the efficiency is relatively low.

[0005] Therefore, it is necessary to develop a forming mechanism for automotive air outlet blades to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a forming mechanism for automotive air outlet blades with high efficiency.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A forming mechanism for automotive air outlet blades, which includes:

[0008] A lower mold, having a lower mold cavity formed by being recessed inward from the surface of the lower mold and a first injection channel for passing plastic connected to the lower mold cavity;

[0012] Furthermore, the driving device includes a driving motor and a synchronous plate that moves with the driving motor. Both ends of the synchronous plate are installed on a lifting mechanism, and the lifting mechanism drives the first upper mold and the second upper mold to move vertically.

[0013] Furthermore, the lifting mechanism has a lifting rod that extends vertically downward and is equipped with a lifting plate at its end. The first upper mold and the second upper mold are respectively installed on the lower surface of the lifting plate.

[0014] Furthermore, the first injection runner includes a first main runner, a first sub-runner and a second sub-runner that communicate with the first main runner. The injection liquid enters the lower mold cavity from the first main runner through the first sub-runner and the second sub-runner.

[0015] Furthermore, a lower mold core is provided in the lower mold. The first sub-runner is formed by being recessed inward from the upper surface of the lower mold core, extends horizontally outward from both sides of the first main runner, and its end communicates with the lower mold cavity.

[0016] Furthermore, the second sub-runner is formed by being recessed inward from the upper surface of the lower mold core, one end communicates with the first sub-runner, and the other end extends horizontally outward and its end communicates with the lower mold cavity.

[0017] Furthermore, the cross-sections of the first sub-runner and the second sub-runner are circular to reduce the resistance of the injection liquid flow.

[0018] Furthermore, the first upper mold includes a first upper mold base and a first upper mold core installed in the first upper mold base. The first upper mold cavity is formed by being recessed inward from the lower surface of the first upper mold core.

[0029] Please refer to Figure 1 , the lower mold 1 includes a lower mold base 11, a lower mold core 12 installed in the lower mold base 11, a first injection runner 13 extending into the lower mold core 12, and a plurality of lower mold cavities 14 connected to the first injection runner 13. The lower mold base 11 includes a fixing part 111 and a limiting part 112. The fixing part 111 is fixedly connected to other devices for determining the position of the lower mold 1. The bottom of the limiting part 112 is fixedly connected to the fixing part 111, and its top extends vertically upward. A rectangular through hole 113 is recessed inward from its upper surface. The rectangular through hole 113 is used for installing the lower mold core 12. A ejector (not shown) is provided between the limiting part 112 and the fixing part 111. The ejector is driven by other power devices to push the formed plastic part out of the lower mold cavity 14. Further, the limiting part 112 has positioning holes 114. In this embodiment, the number of positioning holes 114 is four, which are respectively located at the four corners of the limiting part 112 and are recessed vertically downward from the surface of the limiting part 112.

[0030] The first injection runner 13 includes a first main runner 131, a first sub-runner 132 and a second sub-runner 133 communicated with the first main runner 131. One end of the first main runner 131 is connected to an injection mechanism (not shown), and the other end extends into the lower mold core 12 and is communicated with the first sub-runner 132 and the second sub-runner 133. Both the first sub-runner 132 and the second sub-runner 133 are recessed inward from the upper surface of the lower mold core 12. The first sub-runner 132 extends horizontally outward from both sides of the first main runner 131, that is, one end is communicated with the first main runner 131, the other end extends horizontally outward and the end is communicated with the lower mold cavity 14. One end of the second sub-runner 133 is communicated with the first sub-runner 132, one end extends horizontally outward and the end is communicated with the lower mold cavity 14. Preferably, the first sub-runner 132 and the second sub-runner 133 are perpendicular to each other, and the cross-sections of the first sub-runner 132 and the second sub-runner 133 are circular to reduce the resistance of the injection liquid flow.

[0031] The first upper mold 2 includes a first upper mold base 21, a first upper mold core 22 installed within the first upper mold base 21, and a number of first upper mold cavities 23 formed by inward depressions on the lower surface of the first upper mold core 22. The first upper mold base 21 includes a first fixing portion 211 and a first positioning shaft 212 fixedly connected to the first fixing portion 211. The first fixing portion 211 is used to carry the first upper mold core 22, and it is installed below the driving device 4. The first upper mold core 22 is fixedly connected to the first upper mold base 21 and extends vertically downward from the lower surface of the first upper mold base 21. The structural shapes and positions of the number of first upper mold cavities 23 are the same as those of the number of lower mold cavities 14. Secondly, the first upper mold core 22 also has a first upper mold runner 24, and the shape and position of the first upper mold runner 24 are the same as those of the first injection runner 13. When the first upper mold 2 and the lower mold 1 are clamped, the number of first upper mold cavities 23 and the number of lower mold cavities 14 form a sealed cavity, and the first upper mold runner 24 and the first injection runner 13 form a sealed runner for the injection liquid to flow into the first upper mold cavities 23 and the lower mold cavities 14 to complete the first injection molding. The injection liquid for the first injection molding is a hard rubber with a higher hardness, which is used to strengthen the strength of the blade.

The second upper mold core 32 extends vertically downward from the lower surface of the second upper mold base 31.

[0033] Please refer to Figure 3 , the structure of the second injection runner 33 is the same as that of the first injection runner 13. It includes a second main runner 331 and a second upper mold runner 332. One end of the second main runner 331 is connected to another injection mechanism (not shown), and the other end extends into the second upper mold core 32 to communicate with the second upper mold runner 332. The second upper mold runner 332 has the same structure as the first upper mold runner 24. When the second upper mold 3 and the lower mold 1 are clamped, the second upper mold runner 332 and the first injection runner 13 form a sealed runner.

[0034] A number of second upper die cavities 34 are different in shape from a number of first upper die cavities 23. When the second upper die 3 is clamped with the lower die 1, a number of second upper die cavities 34 and a number of lower die cavities 14 form a sealed cavity, and the space formed by them is larger than the space formed by the sealed cavity formed by the first upper die cavity 23 and the lower die cavity 14. After the injection molding liquid passes through the second upper die runner 332 and the first injection runner 13, it wraps part of the first-molded plastic part to complete the second injection molding. The injection molding liquid for the second injection molding is a soft rubber with a lower hardness, which is used to fill the gap or buffer the collision between the blade and the housing.

[0035] The shapes and positions of the lower die cavity 14, the first upper die cavity 23, and the second upper die cavity 34 are all changed according to requirements.

[0036] Please refer to Figure 4 , the driving device 4 includes a driving motor 41, a synchronous plate 42 that moves with the driving motor 41, a lifting mechanism 43 installed on the synchronous plate 42, and a lifting plate 44 driven by the lifting mechanism 43.

The synchronous plate 42 is a rectangular plate body, and its middle position is connected to the driving motor 41; lifting mechanisms 43 are installed at both ends respectively. The lifting mechanism 43 has a lifting rod 431, and the lifting rod 431 extends vertically downward and the end is installed with the lifting plate 44. The lifting mechanism 43 drives the lifting plate 44 to move vertically through the lifting rod 431. The first upper die 2 and the second upper die 3 are installed on the lower surfaces of both ends of the lifting plate 44 respectively.

[0037] In another embodiment, the driving device 4 is used to drive the lower die 1 to move, that is, the driving motor 41 drives the lower die 1 to move to the first upper die 2 and the second upper die 3 respectively through the synchronous plate 42. The lifting mechanism 43 drives the lifting plate 44 to move vertically through the lifting rod 431 to complete the clamping of the lower die 1 with the first upper die 2 and the second upper die 3 respectively. Secondly, according to requirements, the lifting mechanism 43 drives the lower die 1 to move vertically upward through the lifting rod 431 to complete the clamping of the lower die 1 with the first upper die 2 and the second upper die 3 respectively.

[0038] When the automobile air outlet blade forming mechanism of the present invention is in use, the lifting mechanism 43 drives the lifting plate 44 to move vertically through the lifting rod 431. The first upper mold 2 and the lower mold 1 are closed, so that a plurality of first upper mold cavities 23 and a plurality of lower mold cavities 14 form a sealed cavity, and the first upper mold runner 24 and the first injection runner 13 form a sealed runner. The injection liquid enters from the first main runner 131, passes through the first upper mold runner 24 and the first injection runner 13 to the first upper mold cavity 23 and a plurality of lower mold cavities 14 to complete the first injection molding. The driving motor 41 drives the synchronous plate 42 to rotate, and the second upper mold 3 moves above the lower mold 1. The lifting mechanism 43 drives the lifting plate 44 to move vertically through the lifting rod 431. The second upper mold 3 and the lower mold 1 are closed. The second upper mold runner 332 and the first injection runner 13 form a sealed runner, and the second upper mold cavity 34 and the lower mold cavity 14 form a sealed cavity. The injection liquid enters from the second main runner 331, passes through the second upper mold runner 332 and the first injection runner 13 to the second upper mold cavity 34 and the lower mold cavity 14 to wrap part of the plastic parts formed for the first time.

[0039] The present invention relates to an automobile air outlet blade forming mechanism, which has the characteristics of high efficiency. The driving device drives the first upper mold or the second upper mold to move above the lower mold and dock with the lower mold respectively, so that the first upper mold cavity and the lower mold cavity form a sealed cavity. The first injection molding is completed through the first runner, and the second upper mold cavity and the lower mold cavity form a sealed cavity. The second injection molding is completed through the second runner, thus improving the forming efficiency of the blade.
