Description

Technical Field

[0001] This utility model relates to the field of die-casting molds, and in particular to a cooling structure for a long core-pulling mechanism for an aluminum alloy housing slider of a power steering motor. Background Technology

[0002] The power steering motor housing for automobiles has a cylindrical structure and considerable depth, requiring a relatively long slide core in the die-casting mold. During normal continuous production, the temperature of the slide core increases, and if it is not cooled in time, it will lead to increased product defects and compromise product quality. Therefore, maintaining the correct temperature for the slide core is a crucial factor.

[0003] Effective cooling of the slider core-pulling mechanism has long been a challenge for the die-casting industry in this type of casting. The common cooling method involves installing multiple deep water wells on the slider core-pulling mechanism and connecting these wells to a cooling water source. However, these deep water wells have connection ports, increasing the likelihood of leakage during operation. Once leakage occurs, product quality will plummet. Utility Model Content

[0004] To address the shortcomings of existing technologies, the main objective of this invention is to overcome these deficiencies by disclosing a cooling structure for a long core-pulling slider of an aluminum alloy housing for a power steering motor. The structure includes a slider core and a water jacket. The slider core has an axially recessed mounting groove that mates with the water jacket. Several cooling grooves are spaced circumferentially around the bottom of the mounting groove. A connecting water groove is provided on the lower surface of the water jacket. An inlet pipe and an outlet pipe are provided on the water jacket, and the inlet pipe and outlet pipe are connected to the connecting water groove. The water jacket is disposed within the mounting groove, and the cooling groove communicates with the connecting water groove.

[0005] Furthermore, the cross-section of the water jacket is C-shaped.

[0006] Furthermore, it also includes a partition plate, which is placed inside the cooling tank to form a U-shaped water channel inside the cooling tank.

[0007] Furthermore, a connecting post is provided on the partition, and a connecting hole that mates with the connecting post is provided at a corresponding position on the water jacket.

[0008] Furthermore, the connecting post is tightly fitted with the connecting hole.

[0009] Furthermore, it also includes an extension pipe, which is connected to the water inlet pipe and the water outlet pipe and is placed inside the cooling tank.

[0010] Furthermore, the water jacket is interference-fitted with the mounting groove.

[0011] Furthermore, the joint between the water jacket and the slider core is fixed by welding.

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] This invention utilizes a water jacket / slider core-pulling assembly structure, with connecting water channels linking several cooling tanks, reducing the number of connection interfaces with the cooling source and thus lowering the risk of leakage. By incorporating partitions to form a U-shaped structure within the cooling tanks, the cooling source can circulate. Furthermore, by adding extension pipes to connect the first and last cooling tanks into a circulating water path, the structure becomes compact, further reducing the risk of leakage.

[0029] 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. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] A cooling structure for a long core-pulling mechanism for the aluminum alloy housing slider of a power steering motor, such as... Figures 1-11 As shown, the device includes a slider core 1 and a water jacket 2. The slider core 1 has an axially recessed mounting groove 11 that mates with the water jacket 2. Several cooling grooves 12 are spaced circumferentially around the bottom of the mounting groove 11. A connecting water tank 21 is provided on the lower surface of the water jacket 2. An inlet pipe 22 and an outlet pipe 23 are provided on the water jacket 2, and the inlet pipe 22 and outlet pipe 23 are connected to the connecting water tank 21. The water jacket 2 is located within the mounting groove 11, and the cooling grooves 12 communicate with the connecting water tank 21. This structure reduces the number of connection points to the cooling source, thereby reducing leakage.

[0031] In one embodiment, such as Figures 1-11 As shown, the cross-section of the water jacket 2 is C-shaped; correspondingly, the cross-section of the mounting groove 11 is a matching C-shaped structure. This ensures foolproof installation of the water jacket 2.

[0032] In one embodiment, a partition 3 is also included. The partition 3 is placed in the cooling tank 12 to form a U-shaped water channel in the cooling tank, thereby preventing the cooling water in the cooling tank 12 from undergoing false circulation.

[0033] In one embodiment, such as Figures 1-11 As shown, a connecting post 31 is provided on the baffle 3, and a connecting hole 24 that mates with the connecting post 31 is provided at the corresponding position on the water jacket 2. The connecting post 31 and the connecting hole 24 are tightly fitted together, thus ensuring reliable installation of the baffle 3. The baffle 3 and the water jacket 2 can be assembled first, and the C-shaped structure of the water jacket 2 and the C-shaped structure of the mounting groove 11 ensure that the positions of the baffle 3 and the cooling tank 12 correspond.

[0034] In one embodiment, such as Figures 1-11 As shown, it also includes an extension pipe 4, which is connected to the inlet pipe 22 and the outlet pipe 23 and is placed inside the cooling tank 12. That is, the cooling tank 12 corresponding to the inlet pipe 22 and the outlet pipe 23 forms a circulating water path through the extension pipe 4, ensuring that the cooling source in the cooling tank 12 enters the cooling circulation.

[0035] In one embodiment, such as Figures 1-11 As shown, the water jacket 2 and the mounting groove 11 are interference fit.

[0036] In one embodiment, such as Figures 1-11 As shown, the joint between the water jacket 2 and the slider core puller 1 is fixed by welding. This further improves the sealing performance of the cooling structure.

[0037] When using this utility model, such as Figures 1-11 As shown, the inlet pipe 22 and the outlet pipe 23 are respectively connected to the external cooling source circulation system. The cooling source enters the first cooling tank 12 through the inlet pipe 22 and then enters the last cooling tank 12 through the extension pipe 4. After that, the cooling source enters the cooling source circulation system through the outlet pipe 23 through the extension pipe 4.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
