[0024] Working principle:

[0025] The automobile horn mesh mold mainly comprises a frame 1, a hydraulic cylinder 2, an upper die 4, a lower die 3, a cleaning assembly 5 and an air guide assembly 6, and the various components cooperate with each other to complete the molding of the automobile horn mesh and the cleaning and maintenance of the mold and the like.

[0026] The frame 1 serves as the basic support structure of the entire mold, provides a stable installation basis for the hydraulic cylinder 2, the upper die 4 and the air guide assembly 6 above, and also bears the lower die 3 fixedly connected at the bottom, so as to ensure that the upper and lower dies remain stable in the mold closing, mold opening and injection operations, and create good conditions for the normal operation of the mold.

[0027] The hydraulic cylinder 2 is fixedly connected with the upper die 4 through the telescopic rod at the bottom of the hydraulic cylinder 2, and plays a driving role in the working process of the mold. When the mold closing operation is needed, the telescopic rod of the hydraulic cylinder 2 is elongated to slide, thereby driving the upper die 4 to move downward toward the lower die 3, until the upper and lower dies are tightly closed to form a complete cavity, so that the subsequent injection of plastic melt can be carried out to form the automobile horn mesh. After the forming is completed, the telescopic rod of the hydraulic cylinder 2 is retracted to push the upper die 4 to move upward, thereby realizing the mold opening and facilitating the taking out of the formed product.

[0028] The air guide assembly 6 is responsible for providing high-pressure gas for the cleaning assembly 5 to clean the dust on the surface of the lower die 3. The air shell 61 serves as the main structure of the air guide assembly 6, and is fixed at the top of the inner wall of the frame 1. The air shell 61 is slidably connected with the pressing plate 62 through the push ring 64. The pressing plate 62 has the top spring 63 arranged in a ring array along the central axis thereof. One end of the top spring 63 is fixed to the pressing plate 62, and the other end is fixed to the inner wall of the air shell 61. In the initial state, the top spring 63 is in a natural stretched state, and the push ring 64 is in contact with the top of the upper die 4.

[0029] When the hydraulic cylinder 2 drives the upper die 4 to move upward for mold opening, the upper die 4 pushes the push ring 64 to slide upward along the inner wall of the air shell 61, thereby driving the pressing plate 62 to move upward. The upward movement of the pressing plate 62 compresses the top spring 63, so that the top spring 63 accumulates elastic potential energy. At the same time, the air in the air shell 61 is pushed into the inflation bag 66 through the air outlet pipe 65 under the extrusion of the upward movement of the pressing plate 62. As the air continuously flows in, the inflation bag 66 gradually expands.

[0030] When the mold is closed, the upper die 4 moves downward, the top spring 63 releases the elastic potential energy, and drives the pressing plate 62 to reset downward. At this time, the space in the air shell 61 increases, the pressure decreases, and the outside air will be supplemented into the air shell 61 through the one-way valve at the top of the air shell 61, so as to prepare for the gas extrusion in the next mold opening.

[0031] The cleaning assembly 5 uses the high-pressure gas generated by the air guide assembly 6 to clean the dust on the surface of the lower die 3. The cleaning shell 51 is fixedly connected to the outer wall of the lower die 3, and the outer wall is provided with a linear array of air holes 52, which can uniformly blow the gas to the surface of the lower die 3, and at the same time blow the gas to the formed horn mesh, thereby assisting the demolding of the horn mesh. The fixed shell 54 in the cleaning assembly 5 is connected to the cleaning shell 51 through the connecting pipe 53. The fixed shell 54 is internally fixed with the resistance rod 58 through the support. The top of the resistance rod 58 is fixed with the rubber plug 57, which is in contact with the gas blocking cone plate 55 on the inner wall of the fixed shell 54. The gas blocking cone plate 55 is provided with a ring array of through holes 56.

[0032] When the inflation bag 66 in the air guide assembly 6 is inflated by receiving the air from the air shell 61 during the mold opening process, the high pressure air in the inflation bag 66 enters the fixed shell 54 through the bottom, and the high pressure air impacts the rubber plug 57, overcomes the resistance of the resistance rod 58, causes a gap between the rubber plug 57 and the air baffle plate 55, and the air passes through the through hole 56 on the air baffle plate 55, the connecting pipe 53, and finally the air hole 52 on the cleaning shell 51 to blow to the surface of the lower mold 3 in a high pressure jetting manner, blows away the dust attached to the surface of the lower mold 3, keeps the surface of the lower mold 3 clean, and synchronously blows to the horn net, so as to avoid the dust from mixing into the injection molding material to affect the forming quality of the automobile horn net, and assist the demolding work.

[0033] During the use of the entire automobile horn net mold, each assembly is closely matched according to the working principle described above, and the opening and closing operation of the upper and lower molds is first realized by the hydraulic cylinder 2, the high pressure air generated by the air guide assembly 6 is transmitted to the cleaning assembly 5 during the mold opening process, and the cleaning assembly 5 completes the cleaning work of the surface of the lower mold 3 by using the high pressure air, so as to ensure that the mold can stably perform the injection molding of the automobile horn net, and ensure that the product quality meets the requirements.

[0034] Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled persons in the art and related fields without creative labor should belong to the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model, such as without special description and limitation, are implemented according to the conventional means in the art.
