Description

Technical Field

[0030] To address the problems in the background technology, this utility model proposes a starter motor component housing mold, comprising:

[0031] The workbench 1 has multiple mounting areas 11 on its end face. Each mounting area 11 is configured to accommodate a molding assembly 2 for casting different shell parts. The molding assembly 2 includes an upper mold 22 and a lower mold 21, wherein the lower mold 21 is fixedly installed within the mounting area 11.

[0032] Synchronous lifting mechanism 3, wherein the synchronous lifting mechanism 3 includes:

[0033] A support frame 31 is disposed beside the workbench 1 and has a mounting portion 311 extending between each of the mounting areas 11.

[0034] A connecting frame 32 is located above the worktable 1 and is fixedly connected to multiple upper molds 22 located above each of the lower molds 21.

[0035] The drive unit is located on the top surface of the mounting part 311. Its output end is connected to the center of the connecting frame 32 through a linkage shaft. It is used to drive the connecting frame 32 to lift and lower as a whole, thereby opening and closing the mold.

[0036] Combined with reference Figure 1 and Figure 2 As shown, in this embodiment, the workbench 1 serves as the basic support for the mold. Its top surface is divided into multiple installation areas 11, evenly distributed across the workbench 1 end face, each containing different casting components 2. Each component 2 consists of a lower mold 21 fixed within an installation area 11 and an upper mold 22 located above the lower mold 21. During the molding process, the upper mold 22 presses down on the lower mold 21 to ensure uniform filling of the casting material and achieve the desired molding effect. Both the upper mold 22 and the lower mold 21 have molding cavities, designed to correspond to the end cap, main housing 41, sub-housing, and junction box, respectively. Each upper mold 22 is connected to a synchronous lifting mechanism 3, which consists of a support frame 31, a connecting frame 32, and a drive unit. The support frame 31 is positioned beside the workbench 1 and has installation portions 311 extending between the installation areas 11, supporting and fixing the entire synchronous lifting system for stable and reliable operation. The connecting frame 32 is located above the worktable 1 and is fixedly connected to multiple upper molds 22, ensuring that the upper molds 22 can be raised and lowered synchronously during operation. The drive unit is located on the top surface of the mounting part 311 of the support frame 31. It can be a servo motor 52, an electric cylinder, a hydraulic cylinder 33, etc. Its output end is connected to the center of the connecting frame 32 through a linkage shaft, which can drive the connecting frame 32 to raise and lower as a whole, thereby controlling the opening and closing of the upper mold 22 and the lower mold 21.

[0037] This application utilizes multiple evenly distributed mounting areas 11 on the top of the workbench 1 to accommodate different molding components 2 for casting various outer shell parts. Each molding component 2 consists of a fixed lower mold 21 and an upper mold 22, ensuring uniform filling of the casting material and achieving the desired effect. The molding cavity design corresponds to the end cap, main housing 41, flange, and junction box. The upper mold 22 cooperates with the lower mold 21 via a synchronous lifting mechanism 3. A drive unit (such as a servo motor 52, electric cylinder, or hydraulic cylinder 33) drives the connecting frame 32 to lift and lower as a whole via a linkage shaft, achieving synchronous mold operation. This design improves the accuracy and efficiency of mold opening and closing, and enhances the stability and reliability of the casting process. A single mold can cover the production of all four major components, effectively saving production costs.

[0038] In one possible implementation, the drive unit is a hydraulic cylinder 33, which is connected in a closed loop with a displacement sensor via a PLC controller. The hydraulic cylinder 33 provides strong driving force, ensuring the smooth and efficient operation of the synchronous lifting mechanism 3. The closed-loop connection between the PLC controller and the displacement sensor allows the system to monitor the lifting position of the upper mold 22 in real time and precisely adjust the drive of the hydraulic cylinder 33 based on feedback signals, ensuring accurate opening and closing of the upper mold 22 and lower mold 21, thereby improving the stability, precision, and production efficiency of the casting process. This control method can also achieve automated operation, reduce human intervention, and improve the automation and intelligence level of the production line. The workflow is as follows: aluminum ingots are heated to 680°C and injected into the mold cavity. After cooling, the PLC controls the hydraulic cylinder 33 to rise and open the mold. The ejector mechanism under the lower mold 21 ejects the part, and a robotic arm or manual removal can be added to the worktable 1.

[0039] In one possible implementation, a plurality of auxiliary cooling mechanisms 4 are further included, circumferentially distributed around each of the lower molds 21, each of the auxiliary cooling mechanisms 4 comprising:

[0040] Main housing 41, the main housing 41 having an air passage inside,

[0041] Multiple air-cooled nozzles 42 are provided, each of which is disposed on the side of the main housing 41 facing the lower mold 21 and is connected to the air passage.

[0042] The tracheal connector 43 is located at one end of the main housing 41 and is connected to the airway.

[0043] Combined with reference Figure 1 and Figure 2As shown, in this embodiment, the workbench 1 is also equipped with multiple auxiliary cooling mechanisms 4. These cooling mechanisms are distributed circumferentially around each lower mold 21, aiming to assist the cooling channels inside the molding assembly 2 to provide effective cooling during the casting process, rapidly accelerate the cooling of the mold, prevent overheating, and ensure the quality and precision of the casting. Specifically, each auxiliary cooling mechanism 4 in this application consists of a main housing 41, multiple air-cooled nozzles 42, and an air pipe connector 43. The main housing 41 has an air channel inside to guide the cooling airflow; the air pipe connector 43 is located at one end of the main housing 41, connected to the air channel, and connected to an external air source through this interface to provide the required airflow for the cooling process. The air-cooled nozzles 42 are installed on the side of the main housing 41 facing the lower mold 21. The nozzles are connected to the main housing 41 through the air channel, blowing the cooling airflow onto the surfaces of the lower mold 21 and the upper mold 22 to ensure that the mold receives uniform and effective cooling during the casting process. The auxiliary cooling mechanisms 4 can efficiently blow cold air onto the lower mold 21, rapidly reduce the mold temperature, and prevent overheating from adversely affecting the casting process. Meanwhile, the air pipe connector 43 is connected to an external air source, and the air flow rate can be adjusted as needed to ensure that the cooling effect is controllable and flexible.

[0044] In one possible implementation, each auxiliary cooling mechanism 4 is connected to an angle adjustment mechanism 5, the angle adjustment mechanism 5 comprising:

[0045] Adjustment bracket 51, the main housing 41 is movably installed within the adjustment bracket 51.

[0046] Servo motor 52, the servo motor 52 is located on one side of the adjustment bracket 51, and

[0047] The worm gear transmission assembly 53 is connected to the output end of the servo motor 52 and the main housing 41.

[0048] Combined with reference Figure 2As shown in this embodiment, each auxiliary cooling mechanism 4 is equipped with an angle adjustment mechanism 5, allowing the cooling system to adjust the angle of the cooling nozzles as needed, thereby optimizing the cooling effect and ensuring that the cooling airflow can be precisely directed to the area requiring cooling. Specifically, the angle adjustment mechanism 5 consists of an adjustment bracket 51, a servo motor 52, and a worm gear transmission assembly 53. The adjustment bracket 51 is fixedly mounted on the worktable 1 with fastening screws. The two ends of the main housing 41 are movably mounted within the adjustment bracket 51, allowing the main housing 41 to change angle relative to the bracket, thereby adjusting the angle of the cooling nozzles. The servo motor 52 is mounted on one side of the adjustment bracket 51, serving as the power source for the angle adjustment system. The worm gear transmission assembly 53 connects the output end of the servo motor 52 to the main housing 41, converting the rotational motion of the servo motor 52 into the angle adjustment motion of the main housing 41. The worm gear transmission method has a high reduction ratio and strong torque output, ensuring that the angle adjustment process of the main housing 41 is smooth and stable.

[0049] In one possible implementation, an angle sensor 54 is connected to the side of the adjustment bracket 51 furthest from the servo motor 52. Specifically, to achieve more precise angle control and feedback, an angle sensor 54 is connected to the side of the adjustment bracket 51 furthest from the servo motor 52. The angle sensor 54 is used to monitor the actual angle of the main housing 41 in real time. It can accurately detect the relative position of the adjustment bracket 51 and the main housing 41, providing real-time angle data feedback to the control system. Through the feedback from the angle sensor 54, the system can precisely adjust the angle of the cooling nozzle to ensure that the nozzle always points to the ideal position to optimize the cooling effect.

Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
