Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for air-cooled demolding of automotive structural parts. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. It is suitable for mass production and molding of complex-shaped products.

[0003] Traditional injection molds suffer from slow cooling and solidification rates, resulting in long demolding times and impacting production cycle time. Furthermore, the cooling rates vary significantly across different areas of the product. Traditional static cooling methods are prone to causing localized overheating or uneven shrinkage, leading to quality issues such as warping and deformation of structural components. To address these problems, we propose an air-cooled demolding injection mold for automotive structural components. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4An injection mold for air-cooled demolding of automotive structural components includes: a fixed mold 1 and a moving mold 2. An air-cooling mechanism 3 is provided on the side of the fixed mold 1. The air-cooling mechanism 3 includes a distribution pipe 31 for diverting cooling airflow and a base frame fixedly connected to the fixed mold 1. The base frame is integrally formed from a base plate 32, a fixed seat 33, a reinforcing block 34, and a connecting seat 35, eliminating welding or assembly gaps, improving structural strength and vibration resistance, and ensuring long-term stable operation of the distribution pipe 31. A connecting ring 36 is fixedly installed on the surface of the distribution pipe 31, and the distribution pipe 31 is rotatably connected to the connecting seat 35 through the connecting ring 36. The base plate 32 is fixedly connected to the fixed mold 1. A pipe clamp 38 is fixedly installed on the side of the reinforcing block 34, and the reinforcing block 34 is connected to a connecting hose 37 through the pipe clamp 38. One end of the connecting hose 37 is connected to the distribution pipe 32. The air inlet of mold 1 is fixedly connected, and the other end of the connecting hose 37 is connected to the source of cooling airflow. The inside of the split pipe 31 is hollowed out, and the surface of the split pipe 31 is provided with one air inlet and three air outlets. The split pipe 31 evenly distributes the cooling airflow to the surface of the product, directly acting on the key area to improve local cooling efficiency. The fixed seat 33 and the connecting seat 35 are designed with a Z-shaped structure. There is a gap between the connecting seat 35 and the surface of the fixed mold 1 to provide gap space and avoid interference between the split pipe 31 and the surface of the fixed mold 1 when rotating, while enhancing the load-bearing capacity of the base frame. The split pipe 31 is located at the joint between the fixed mold 1 and the moving mold 2, and the air outlet of the split pipe 31 faces the joint between the fixed mold 1 and the moving mold 2. There are two fixed seats 33 in total, and the two sides of the reinforcing block 34 are fixedly connected to the two fixed seats 33 respectively.

[0017] The base frame is also equipped with a reversing mechanism 4, which includes a telescopic cylinder 43 fixedly connected to the reinforcing block 34 and a guide rail 46 fixedly connected to the fixed base 33. An L-shaped connecting rod 41 is slidably mounted on the outer surface of the guide rail 46. The guide rail 46 ensures the straightness of the movement trajectory of the L-shaped connecting rod 41, improving the stability and reliability of the entire reversing process. A drive rack 44 is fixedly mounted on the surface of the L-shaped connecting rod 41. An auxiliary gear 45 is meshed with the side of the drive rack 44. The auxiliary gear 45 is fixedly connected to the splitter pipe 31. A fixed rod 42 is fixedly installed at the end of the L-shaped connecting rod 41. The fixed rod 42 is fixedly connected to the piston rod of the telescopic cylinder 43. The telescopic cylinder 43 transmits power through the fixed rod 42 and the L-shaped connecting rod 41 to realize the automatic adjustment of the angle of the diverter 31 without manual intervention. Both ends of the diverter 31 are provided with auxiliary gears 45. The number of drive racks 44 is the same as the number of auxiliary gears 45. The gear transmission is used to ensure the accuracy and synchronization of the angle adjustment of the diverter 31 and avoid the swaying or jamming of the diverter 31 when it rotates.

[0018] Working principle: The base plate 32, the fixed seat 33, the reinforcing block 34, and the connecting seat 35 are integrally formed to form a base frame. The distribution pipe 31 is connected to the side of the fixed mold 1 through this base frame. Therefore, after the moving mold 2 is opened to expose the product solidified on the fixed mold 1, the heat dissipation airflow is blown into the distribution pipe 31 through the connecting hose 37, and then distributed through multiple air outlets of the distribution pipe 31 to blow onto the plastic product, reducing its temperature to facilitate demolding. After the telescopic cylinder 43 on the side of the reinforcing block 34 is activated, the L-shaped connecting rod 41, which is integrally formed with the fixed rod 42, connects to the fixed seat 35. The guide rail 46 on the side of the 3 is slidably connected, and the drive rack 44 is fixed on the side of the L-shaped connecting rod 41. The drive rack 44 meshes with the auxiliary gear 45 fixed on the end face of the diversion pipe 31. Therefore, after the telescopic cylinder 43 is started, the drive rack 44 can be driven to slide through the fixed rod 42 and the L-shaped connecting rod 41 in sequence. After the drive rack 44 slides, the diversion pipe 31 can be driven to rotate on the connecting seat 35 in sync through the auxiliary gear 45, so as to change the direction of the cooling airflow sprayed out by the diversion pipe 31, thereby blowing it to different areas of the product, improving cooling efficiency, and quickly meeting the demolding requirements.
