Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a cooling and solidification tool for an automotive generator protective cover. Background Technology

[0002] Cooling and solidification tools play a crucial role in mold manufacturing, especially in the production of automotive parts. Take automotive alternator covers as an example: these molds must withstand continuous high temperatures and pressures during plastic injection molding, metal die casting, or rubber product manufacturing. Inefficient cooling not only significantly prolongs the product molding cycle and reduces production efficiency, but can also cause quality defects such as dimensional deformation of the cover and surface weld lines, severely affecting the assembly accuracy and sealing performance of the automotive alternator. Furthermore, long-term heat load accumulation can cause localized cracking and water channel corrosion of the mold, significantly shortening its lifespan and increasing maintenance costs for enterprises.

[0003] Traditional mold cooling technologies largely rely on internal water or air circulation coolant. However, these methods exhibit significant drawbacks in complex mold applications such as automotive generator covers, which have numerous internal ribs and curved surfaces: dead zones in coolant flow lead to localized overheating, and uneven cooling efficiency results in significant differences in shrinkage rates across different parts of the cover, ultimately causing warping and deformation. With the increasing demands for generator performance and lightweighting in new energy vehicles, the design complexity of protective covers continues to rise, posing greater challenges to the heat dissipation efficiency, temperature control accuracy, and energy consumption performance of cooling technologies. Existing cooling solutions are insufficient to meet the multiple requirements of efficient heat dissipation, energy conservation and environmental protection, and long-term mold use.

[0004] In recent years, cooling and solidification tools have gradually emerged, achieving uniform cooling during mold processing through optimized cooling channel design, effectively improving the molding quality and production efficiency of protective cover products. However, facing the stringent requirements of the automotive industry for component cost control, existing tools still suffer from high manufacturing costs, limited mold compatibility, and difficulties in maintaining complex structures. Developing a cooling and solidification tool that combines structural rationality, excellent cooling efficiency, and strong adaptability has become a key challenge in achieving high-quality, low-cost production of automotive alternator protective covers.

[0030] Example

[0031] like Figures 1-3 As shown, this embodiment provides a cooling and solidification tool for an automotive generator protective cover, including: a base 1, a protective cover 2 mounted on the base 1, a limiting mechanism 3 positioned directly above the protective cover 2 for fixing the protective cover 2, and a cooling mechanism 4 disposed inside the base 1 for cooling the protective cover 2. The limiting mechanism 3 stably fixes the protective cover 2, and the cooling mechanism 4 is mainly used to cool the protective cover 2 to meet the temperature control requirements of the protective cover 2 during production or use, prevent it from being damaged or deformed due to high temperature, and improve the quality and service life of the protective cover 2. The two are used together to ensure that the shape and performance of the protective cover 2 meet the requirements, that is, to effectively remove heat from the mold, accelerate the cooling speed, shorten the molding cycle, improve the production cycle, prevent overheating, ensure molding quality, and meet the needs of high-efficiency production.

[0032] The limiting mechanism 3 includes: a fixed base 31, a first connecting rod 32 rotatably connected to one end of the fixed base 31, a second connecting rod 33 rotatably connected to the other end of the fixed base 31, a pull rod 34 disposed above the fixed base 31 and rotatably connected to the first connecting rod 32 and the second connecting rod 33 respectively, and a fixing component 35 disposed on the second connecting rod 33. The cooling mechanism 4 is disposed below the limiting mechanism 3. The rotatable connection provides flexible adjustment capability, allowing the limiting mechanism 3 to be adjusted according to the shape and size of the protective cover 2, specifically the outer diameter and thickness of the protective cover 2, to better adapt to different specifications of protective covers 2 and improve the versatility of the tool.

[0033] Meanwhile, the fixing component 35 includes: a fixing rod 351 vertically disposed at one end of the second connecting rod 33 and a pressure block 352 disposed at the bottom of the fixing rod 351, which is used to directly contact the protective cover 2 and apply pressure to achieve fixing of the protective cover 2.

[0034] In this embodiment, the fixing rod 351 can be a threaded pin, and the pressure block 352 can be a ring buckle. The pressure block 352 increases the force-bearing area, making the protective cover 2 more stable and secure, and preventing it from shifting.

[0035] In this embodiment, the second connecting rod 33 is hollow inside, and the fixing rod 351 is slidably connected inside the second connecting rod 33. One end of the fixing rod extends outward to ensure that there is enough space to fix the protective cover 2. This allows the fixing component 35 to make appropriate extension and retraction adjustments according to the actual situation such as the thickness of the protective cover 2 when fixing the protective cover 2, further enhancing the adaptability and fixing effect of the limiting mechanism 3, and ensuring that the protective cover 2 can remain stable during the cooling process without loosening or displacement.

[0036] In this embodiment, both the first link 32 and the second link 33 can be long rings, which facilitates the formation of a rotating structure, making the limiting mechanism 3 a movable structure, and also reduces weight and cost.

[0037] In this embodiment, the fixed base 31, the first connecting rod 32, the second connecting rod 33, and the pull rod 34 are interconnected to form a four-bar structure. The first connecting rod 32 and the second connecting rod 33 are connected to the base 1 in an oblique and vertical manner, respectively, to ensure structural stability. This design enables the four-bar mechanism to maintain good stability and force balance during equipment operation, improves overall working performance and safety, and effectively ensures long-term efficient and reliable operation of the equipment.

[0038] In this embodiment, the cooling mechanism 4 includes: several joints disposed on both sides of the base 1 and a cooling pipe 42 disposed on the interface 41 for introducing cooling medium. The cooling pipe 42 completely penetrates the base 1, so that the cooling medium can flow fully inside the base 1 to achieve effective cooling of the protective cover 2.

[0039] In this embodiment, the cooling pipe 42 is made of polyethylene (PE). PE has good corrosion resistance and insulation properties, which can effectively reduce the cost and weight of the system. In addition, PE material has good flexibility and low thermal conductivity, which helps to keep the coolant flowing smoothly, reduce energy consumption and heat loss, ensure the efficient and stable operation of the cooling system, and facilitate installation and maintenance, thereby reducing the overall cost.

[0040] In this embodiment, the through-type design of the cooling pipe 42 is also conducive to the uniform distribution and rapid circulation of the cooling medium, improving cooling efficiency and ensuring that the protective cover 2 can cool down quickly and evenly to meet the temperature requirements during production or use.

[0041] In this embodiment, the cooling pipe 42 and the mounting groove 11 do not interfere with each other, ensuring that the installation and cooling process of the protective cover 2 do not affect each other, thus improving the overall performance and reliability of the tool.

[0042] In this embodiment, the size of the mounting groove 11 is adapted to the size of the protective cover 2, and more preferably the size of the mounting groove 11 is greater than or equal to the size of the protective cover 2, so as to ensure that the protective cover 2 can be accurately and stably installed on the base 1.

[0043] In this embodiment, the fixing seat 31 is fixedly connected to the base 1 by a number of fasteners 36. The fasteners 36 are preferably bolts, which have a simple structure and are easy to assemble and disassemble.

[0044] In this embodiment, the fixing seat 31 and the mounting groove 11 do not interfere with each other. Preferably, the fixing seat 31 is located on one side of the mounting groove 11, which ensures that the installation of the protective cover 2 and the fixing operation of the limiting mechanism 3 do not affect each other, thereby improving the ease of use and work efficiency of the tool.

[0045] In this embodiment, the cooling pipe 42 passes through the base 1, which can achieve efficient heat dissipation and cooling functions. The cooling medium circulates in the cooling pipe 42, which can effectively remove the heat generated during the mold operation, ensure that the equipment operates at a stable temperature, and prevent failures or damage caused by overheating. Moreover, the design is compact, easy to install, and improves the overall heat dissipation efficiency and service life of the equipment.

[0046] In this embodiment, the present invention is widely used in the mold cooling process of injection molding, die casting, rubber and metal forming, and is suitable for scenarios requiring efficient temperature control in the manufacturing of automotive parts, home appliance housings, electronic products and other products.

[0047] Of course, the base 1 can be made of aluminum. The base 1 mainly serves to support and fix the structure, requiring a certain degree of rigidity and strength, but not extremely high hardness. It also serves a certain function of heat dissipation.

[0048] In addition, the protective cover 2 can be made of carbon fiber composite material, which is lightweight and high-strength, and can provide heat dissipation and safety protection.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
