Description

Technical Field

[0001] This utility model relates to the technical field of garbage can liner manufacturing equipment, specifically a garbage can liner manufacturing equipment with rapid cooling of injection mold. Background Technology

[0002] Trash can liner manufacturing equipment is typically used to produce the inner liner of trash cans. These liners are usually made of plastic and have properties such as being waterproof, leak-proof, and wear-resistant. Injection molds are usually used in trash can liner manufacturing equipment. When manufacturing trash can liners, the plastic material is heated to a molten state and then injected into the mold cavity. After cooling and solidification, the desired trash can liner is finally obtained.

[0003] For example, an injection mold for producing classified garbage bins, as disclosed in announcement number CN221365610U, includes a moving mold base and a fixed mold base. The moving mold base is located at the bottom of the fixed mold base. A mold core with a right-angled trapezoidal side cross-section is provided at the center of the moving mold base. A side groove is provided at the top of the moving mold base, located on the outer periphery of the bottom surface of the mold core. A ventilation pipe is provided connecting the moving mold base and the mold core. An air pump is fixedly installed on one side of the moving mold base, and the output port of the air pump is connected to the inlet of the ventilation pipe. A cavity matching the mold core is provided at the bottom of the fixed mold base. An injection port is provided at the top of the cavity. A cooling pipe is provided inside the fixed mold base on the outer side of the cavity. An exhaust valve is provided on one side of the fixed mold base. An air pump is installed on the side opposite the exhaust valve and fixed on the fixed mold base. The air pump is connected to the cooling pipe.

[0004] The aforementioned patent proposes that the injection cavity can be cooled by cold air to accelerate the cooling and molding of the injection molded parts. However, during the use of the injection mold for manufacturing the inner liner of the trash can, the cold air is drawn into the cooling pipe by the air pump. However, the air cooling method cannot effectively cover the entire mold surface, which makes the overall cooling of the mold slow down. This affects the production speed of the inner liner of the trash can, resulting in a slower overall production rate. Utility Model Content

The air-cooling component 42 is used to blow air and works with the water tank 41 and the air-cooling component 42 to cool down the lower mold base 2, thereby achieving rapid cooling and accelerating the molding of the inner liner of the trash can.

[0024] An injection port 31 is provided on the surface of the upper mold base 3, a mold cavity 32 is provided inside the upper mold base 3, a positioning groove 33 is provided on the bottom wall of the upper mold base 3, and the mold cavity 32 communicates with the inside of the injection port 31.

An extension groove 24 is opened on the surface of the lower mold base 2.

[0026] The air-cooled component 42 includes a support 421 and an air pump 422 installed on the upper end of the support 421.

When the control valve 427 is opened, the gas can be discharged from the exhaust pipe 426.

[0027] The water-cooled component 43 includes a water-cooling pipe 431 and a circulation pipe 432. The water-cooling pipe 431 is placed on the side wall of the water tank 41, and a valve is installed on the water-cooling pipe 431.

The exhaust valve 411 can also be used to expel the gas in the water tank 41. When the coolant flows back into the water tank 41, the heat dissipation fins 44 can quickly dissipate heat from the coolant. At the same time, the suction pump 422 is started, and the bent suction pipe 425 can draw air, which increases the airflow speed around the heat dissipation fins 44 and effectively speeds up the heat dissipation.
