[0002] Injection molds are devices used for plastic molding, including components such as injectors, heating systems, and parting lines. Mold materials are typically made of metals such as carbon steel, stainless steel, or alloy steel to ensure stability. The injection molding process usually includes steps such as heating and melting plastic granules, injecting molten plastic granules, cooling and solidifying them through the mold, and demolding. The mold plays a role in cooling and solidifying plastic products. When the hot molten material enters the cooled injection mold, a large amount of steam is generated. The usual practice is to create venting grooves on the mold surface to balance the air pressure. However, the venting grooves are small in diameter, making them difficult to clean. Over time, the venting grooves are easily clogged by splashed plastic particles, which can damage the injection mold and reduce product quality.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-3 As shown, a sunshade curtain shell injection mold with rapid cooling function includes a first mold 101, a second mold 102 on the side of the first mold 101, an injection port on the surface of the second mold 102, the injection port being connected to an injection molding machine 103, a molding cavity 104 between the first mold 101 and the second mold 102, two drive columns 105 slidably connected to the first mold 101, a first spring 106 on the outside of the drive columns 105, one end of the first spring 106 being fixedly connected to the surface of the first mold 101, and the other end of the first mold 101 being fixedly connected to the surface of a fixing plate 107, a fixed end of a telescopic rod 108 being fixedly connected to the middle of the fixing plate 107, and an output end of the telescopic rod 108 being fixedly connected to the first spring 104. A mold 101 is provided on its surface. The first mold 101 is equipped with a venting mechanism and a cooling structure on its lower side. The first mold 101 and the second mold 102 are assembled. High-temperature liquid material is injected into the molding cavity 104 through the injection molding equipment 103. The high-temperature liquid material contacts the molding cavity 104. During the liquid material filling process, the first mold 101 and the second mold 102 are used to cool the liquid material and make it plastic. After plasticization is completed, the telescopic rod 108 retracts to drive the first mold 101 to move. The transmission column 105 slides in the first mold 101 and ejects the plasticized injection part. The first spring 106 and the fixed block cooperate to provide pressure and guidance for the movement of the first mold 101.
[0025] In one embodiment, such as Figure 2 and Figure 4As shown, the venting mechanism includes venting grooves 301. Two venting grooves 301 are disposed inside the first mold 101. The venting grooves 301 are connected to the molding cavity 104. A sliding seat 302 is fixedly connected to the inner wall of the venting groove 301. An opening is provided on the surface of the sliding seat 302. A sliding rod 303 is slidably connected in the middle of the sliding seat 302. A sealing component for automatically closing the molding cavity 104 is provided on the sliding rod 303. When the high-temperature liquid material comes into contact with the first mold 101 and the second mold 102, a large amount of steam is generated. The steam is discharged through the venting grooves 301 and the sliding seat 302 provides conditions for automatically closing the molding cavity 104.
[0026] In one embodiment, such as Figure 2 and Figure 4 As shown, the sealing assembly includes a sealing plug 304, which is fixedly connected to one end of a sliding rod 303. The other end of the sliding rod 303 is provided with a second spring 305. One end of the second spring 305 is fixedly connected to a sliding seat 302, and the other end of the second spring 305 is fixedly connected to the surface of the sliding rod 303. Steam pushes the sealing plug 304 to move, so that the venting groove 301 communicates with the molding cavity 104. Gas enters the venting groove 301 and is discharged. When the gas is discharged, the second spring 305 drives the sliding rod 303 to reset, and the sliding rod 303 drives the sealing plug 304 to reset. The sealing plug 304 isolates the venting groove 301 and the molding cavity 104, providing conditions for injection molding.
[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the cooling structure includes a cooling pipe 201. Both the first mold 101 and the second mold 102 are equipped with cooling pipes 201. Two water pipes 202 are located at the lower ends of both the first mold 101 and the second mold 102. The water pipes 202 connect to the cooling pipes 201. A water pump 203 is installed on the surface of the water pipes 202. The lower end of the water pipes 202 connects to a heat dissipation element. Circulating water is transported to the cooling pipes 201 through the water pipes 202. The circulating water flows within the cooling pipes 201 and exchanges heat with the first mold 101 or the second mold 102, completing the cooling process. By extending the cooling path through the water pipes 202, the heated circulating water dissipates heat through the external air during circulation, losing some heat and reducing the cooling pressure.
[0028] In one embodiment, such as Figure 2 and Figure 3As shown, the heat dissipation element includes a cooling box 204, which is connected to a water supply pipe 202. The surface of the cooling box 204 is provided with heat dissipation fins 205, and a cooling fan 206 is provided in the middle of the heat dissipation fins 205. The water pump 203 provides power for water circulation, the cooling box 204 stores circulating water, the heat dissipation fins 205 increase the heat dissipation area of the cooling box 204, and the cooling fan 206 causes airflow to exchange heat with the cooling box 204 to cool the circulating water.
[0029] The above embodiment discloses a sunshade curtain shell injection mold with rapid cooling function. A first mold 101 and a second mold 102 are assembled. High-temperature liquid material is injected into the molding cavity 104 through an injection molding machine 103. During the liquid filling process, the first mold 101 and the second mold 102 cool the liquid material, causing it to cool and plasticize. After plasticization, a telescopic rod 108 retracts, driving the first mold 101 to move. A transmission column 105 slides within the first mold 101, ejecting the molded part. The first spring 106 and the fixing block work together to provide pressure and guidance for the movement of the first mold 101. When the high-temperature liquid material contacts the first mold 101 and the second mold 102, a large amount of steam is generated. The steam is discharged through a venting groove 301. A sliding seat 302 provides conditions for automatically closing the molding cavity 104. The steam pushes the sealing plug 304 to move, thus venting the air. The venting groove 301 is connected to the molding cavity 104. Gas enters the venting groove 301 and is discharged. After the gas is discharged, the sliding rod 303 is reset by the second spring 305. The sliding rod 303 resets the sealing plug 304. The sealing plug 304 isolates the venting groove 301 and the molding cavity 104, providing conditions for injection molding. Circulating water is transported to the cooling pipe 201 through the water supply pipe 202. The circulating water flows in the cooling pipe 201 and exchanges heat with the first mold 101 or the second mold 102 to complete the cooling work. By setting the water supply pipe 202 to extend the cooling route, the heated circulating water dissipates heat through the external air during the circulation process, losing a certain amount of heat and reducing the cooling pressure. The water pump 203 provides power for the water circulation. The circulating water is stored in the cooling tank 204. The heat dissipation area of the cooling tank 204 is increased by the heat dissipation fins 205. The cooling fan 206 causes the airflow to exchange heat with the cooling tank 204, cooling the circulating water.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
