[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model discloses a car speaker cover mold, such as Figure 1 As shown, the die body 1 includes an upper die 2 and a lower die 3, both of which are made of high-strength, high-temperature resistant chromium-molybdenum-vanadium alloy tool steel to ensure good dimensional stability and wear resistance during a long-term die-casting process.

[0019] like Figure 1 、 Figure 3 、 Figure 4 As shown, the cleaning device installed on the mold body 1 is used to promptly clean impurities and residues on the mold surface to ensure the normal operation of the mold and product quality. The cleaning device consists of an air pump 4, a connecting rod 5, a control component 6, and an air outlet pipe 7. The connecting rod 5 is divided into a first connecting rod 8 and a second connecting rod 9. The two are arranged on opposite sides of the mold body 1 and are hinged to the mold body 1 via a durable stainless steel hinge to ensure that the connecting rod 5 can rotate flexibly. The air outlet pipe 7 is made of lightweight and high-strength aluminum alloy, and its ends are firmly welded to the first connecting rod 8 and the second connecting rod 9 respectively. The air pump 4 is installed below the first connecting rod 8. The air pump 4 is a small vortex air pump 4 with moderate power and stable air pressure. The air pump 4 is equipped with an air outlet and an air inlet. The control component 6 is installed on the side of the first connecting rod 8 away from the mold body 1. The control component 6 includes a container 10, a slider 11, a slide rod 12, and a pressure sensor 13. One end of the slide rod 12 is welded to the top of the container 10, and the other end is welded to the bottom of the container 10. A slide rod 12 extends through the slider 11, which is made of wear-resistant nylon. A slight gap is left between the slide rod 12 and the slider 11 to ensure smooth sliding of the slider 11. A pressure sensor 13 is mounted at the bottom of the housing 10, located on one side of the slide rod 12. This pressure sensor 13 is a high-precision, highly responsive resistive pressure sensor. It is electrically connected to the air pump 4 via waterproof wiring. A flexible rubber hose 14 is installed between the air outlet of the air pump 4 and the first connecting rod 8 to cushion vibrations and provide a certain amount of flexibility. The first connecting rod 8 has a hollow cavity within it, which is connected to the hose 14 and also to the air outlet pipe 7. Multiple air outlets 15 are evenly distributed on the air outlet pipe 7. When the air outlet pipe 7 is lifted, the air outlets 15 can blow air to clean the surface of the lower mold cavity 18. The upper mold 2 and lower mold 3 together form the mold cavity for manufacturing the car horn cover. The lower mold 3 is equipped with several ejector pins 16 made of hard alloy with high hardness and strong wear resistance. The upper mold 2 is equipped with a sprue bushing made of high-temperature resistant hot-working die steel. The sprue bushing is located at the thickest part of the bell housing cavity to ensure that the molten material can fill the cavity evenly and quickly.

[0020] like Figure 1 、 Figure 2 、 Figure 3 As shown, the mold cavity is further divided into an upper mold cavity 17 and a lower mold cavity 18. A cooling duct 19 is arranged below the lower mold cavity 18. The cooling duct 19 is made of copper tube with excellent thermal conductivity. One end of the cooling duct 19 is connected to the air inlet, and the other end is connected to the outside world. This allows air to circulate during operation, removing heat from the lower mold cavity 18, thereby improving production efficiency and product quality. A handle 20 is installed on one side of the first connecting rod 8 for easy operation. The handle 20 is wrapped with a non-slip and heat-insulating rubber material to facilitate the operator to adjust the position of the connecting rod 5.

[0021] Working principle: In actual use, after the lower cavity 18 is separated from the upper cavity 17, the mold is removed. The operator holds the handle 20 and rotates the connecting rod 5 to align the air outlet 7 with the area that needs to be cleaned. The slider 11 then moves along the slide bar 12 due to gravity and contacts the pressure sensor 13. After receiving the pressure signal, the pressure sensor 13 activates the air pump 4. The air flows through the cooling pipe 19, then through the hose 14 and the cavity of the first connecting rod 8, into the air outlet 7, and is blown out from the evenly distributed air outlets 15, effectively cleaning the surface of the lower cavity 18. When the cleaning device is in the initial position, the slider 11 is away from the pressure sensor 13, and the air pump 4 will not be activated, saving resources.

[0022] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
