Technical Field

[0001] This utility model relates to the field of automotive motor controller technology, and in particular to a die-casting mold for producing end caps for automotive motor controllers. Background Technology

[0002] The motor controller is one of the key components of new energy vehicles. It is the main component that directly controls the electric motor, and its performance will directly affect the working condition of the motor.

[0003] The motor controller end cover is an important component of the motor controller. As shown in the figure, the motor controller end cover includes an end cover body 24, on which an interface 25 is provided. Multiple grooves 26 are formed on the bottom surface of the interface 25. To assist in the structural forming of the interface 25 and the multiple grooves 26, a hydraulic cylinder is typically used to directly drive a forming rod, with the end of the forming rod assisting in the forming of the grooves 26. However, this structure generally has low stability. Therefore, a corresponding support guide needs to be designed between the hydraulic cylinder and the forming rod to ensure stable operation. However, such a support guide does not currently exist, and the design must also consider ease of manufacturing and cost. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a die-casting mold for producing end caps of automotive motor controllers. The design includes a structure for supporting guide components, which are further divided into three parts: a main cylinder, an end cap, and a sleeve. The parts are positioned internally and externally to ensure accuracy, and then fixed by welding. This effectively reduces the processing difficulty.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A die-casting mold for producing end caps for automotive motor controllers is provided, including an upper mold frame and a lower mold frame. An upper mold core and a lower mold core are stacked vertically between the upper and lower mold frames. A mold cavity is provided between the upper and lower mold cores. A vertically inserted interface insert is installed inside the lower mold core. Multiple vertically sliding forming rods are installed inside the interface insert. A lower template is installed below the lower mold frame. A small hydraulic cylinder is installed at the bottom of the lower template. The small hydraulic cylinder is positioned between the interface insert and the interface core. A support guide is installed, within which a drive rod that slides up and down is installed. The upper end of the drive rod is connected to a forming rod, and the lower end of the drive rod is connected to the piston rod of a small hydraulic cylinder. The support guide includes a main body cylinder, an end cap, and a sleeve. The bottom of the end cap is provided with a mating boss, and a through hole is provided on the mating boss for the forming rod to pass through. The mating boss is inserted into the upper opening of the main body cylinder and fixed by welding. The inner wall of the upper opening of the sleeve is provided with a mating groove, and the lower part of the main body cylinder is inserted into the mating groove and fixed by welding.

[0006] As a supplement to the technical solution described in this utility model, a mold foot is installed on each side of the lower end of the lower mold frame, and a top plate assembly is provided between the two mold feet. The top plate assembly is provided with multiple push rods that are inserted into the mold cavity. The lower mold plate is fixedly installed on the lower ends of the two mold feet, and the support guide penetrates through the top plate assembly.

[0007] As a supplement to the technical solution described in this utility model, the upper end of the drive rod is provided with an inverted T-shaped slot, and the lower part of the forming rod is provided with a snap-fit ​​part that cooperates with the slot.

[0011] Beneficial Effects: This utility model relates to a die-casting mold for producing end caps for automotive motor controllers. The upper end of the interface insert is used to assist in the forming of the interface, and the upper end of the forming rod is used to assist in the forming of the groove. The lower end of the interface insert is supported by a support guide. After the product is formed, the small hydraulic cylinder first controls the drive rod to move downward, and the drive rod moves downward along with the forming rod, causing the upper end of the forming rod to separate from the formed groove. Then, the upper mold frame and upper mold core are controlled to separate from the lower mold frame and lower mold core. The formed product is ejected by the top plate assembly with the ejector rod. This utility model designs a structure for the support guide and also disassembles the support guide into three parts: the main body cylinder, the end cap, and the sleeve. The parts are positioned internally and externally to ensure accuracy, and then fixed by welding. This effectively reduces the processing difficulty and manufacturing cost. The sleeve covers the connection between the drive rod and the piston rod of the small hydraulic cylinder. The inner wall of the main body cylinder is used to guide the drive rod to slide stably up and down, and the perforation on the end cap is used to guide the forming rod to slide stably up and down.
