Description

Technical Field

[0001] This utility model relates to the field of heat sink stamping technology, specifically to a heat sink stamping equipment for automotive LED headlight production. Background Technology

[0002] The heat sink for automotive LED headlights refers to the component used to help dissipate heat from LED headlights. Its main function is to effectively dissipate the heat generated by the LED headlights during operation, preventing excessive temperature from affecting the lifespan and performance of the LED chips. It is usually produced by stamping. For example, the Chinese authorized patent with announcement number CN118045905A (a heat sink stamping device with deformation control function) includes a power unit for converting circular motion into linear motion. The stamping device also includes a punch press, a forming device, and a transfer device. The punch press has a drive cavity, and the power unit is placed in the drive cavity. The power unit drives the forming device to move linearly. The forming device is connected to the punch press. The transfer device is used to transfer the heat sink. The power unit adopts a conventional rotary drive structure, driven by a main motor, which drives the flywheel to rotate. Through the clutch, it drives the transmission gears, crankshaft, connecting rod, etc. to rotate, converting the torque into linear motion, thereby driving the forming device to slide along the punch press to stamp the heat sink. The transfer device enables automated loading and unloading, improving forming efficiency. The punch press serves as the main mounting base for installing and fixing other devices.

[0003] However, most existing stamping machines used for heat sinks in automotive LED headlights rely on direct bolt fixing when installing the stamping die base. This often results in misalignment between the upper and lower die bases, leading to poor stamping quality. Furthermore, the upper die base lacks support during installation and is prone to falling, causing installation inconvenience. Therefore, these methods do not meet current requirements. To address this, we propose a heat sink stamping equipment for automotive LED headlight production. Utility Model Content

[0004] The purpose of this utility model is to provide a heat sink stamping equipment for automotive LED headlight production, in order to solve the problems mentioned in the background art. In most cases, when installing the stamping die base, the existing stamping machines used for automotive LED headlight heat sinks are directly fixed with bolts, which easily leads to misalignment of the upper and lower die bases, resulting in poor stamping and forming effect. Furthermore, when installing the upper die base, the upper die base lacks support and is prone to falling off, causing inconvenience in installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat sink stamping equipment for automotive LED headlight production, comprising: a base, a lower die base at the upper end of the base, an upper die base above the lower die base, a connecting seat at the center of the upper end of the upper die base, positioning components on both sides between the base and the top plate, guide posts on the upper surface of the corners of the base, guide grooves on the upper surface of the corners of the top plate, the guide posts being inserted into the guide grooves, and the top plate moving up and down along the guide posts via the guide grooves.

[0006] Preferably, the positioning component includes a positioning frame and a positioning plate, with the positioning frame located on both sides of the lower mold base and the positioning plate located on both sides of the upper mold base. A moving groove is provided on one side surface of the positioning frame, and the positioning plate moves up and down along the moving groove.

[0007] Preferably, mounting plates are provided at both ends of the positioning frame, a first screw is provided on one side of the mounting plate, and the mounting plate is fixed to the lower mold base by the first screw, and a second screw is provided on one side of the top of the positioning plate, and the positioning plate is fixed to the upper mold base by the second screw.

[0008] Preferably, the upper surface of the base is provided with a slot at the same vertical and horizontal position as the moving groove.

[0009] Preferably, a first stabilizing groove is provided at the center of the upper surface of the base, and a first stabilizing slide is provided at the center of the lower surface of the lower mold base, and the first stabilizing slide moves along the first stabilizing groove.

[0010] Preferably, a second stabilizing groove is provided at the center of the lower surface of the top plate, and a second stabilizing slide is provided at the center of the upper surface of the upper mold base, and the second stabilizing slide moves along the second stabilizing groove.

[0011] Preferably, the front and rear surfaces of both ends of the lower mold base and the upper mold base are provided with fixing plates, and the upper end of the fixing plates is provided with fixing bolts. The lower mold base and the upper mold base are fixed to the base and the top plate respectively by fixing plates and fixing bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model connects the lower mold base and the upper mold base through the positioning component. When installing the lower mold base and the upper mold base, the positioning plate moves up and down along the moving groove to adjust the height between the lower mold base and the upper mold base, so that the lower mold base and the upper mold base remain vertical and horizontal and do not deviate. The first stable slide moves along the first stable slide groove, and the second stable slide moves along the second stable slide groove, which improves the connection stability of the lower mold base and the upper mold base. In particular, the installation of the upper mold base can play a limiting and anti-falling effect, without the need for manual support, which improves the convenience of installation. When disassembling the base and the top plate, the positioning component allows the base and the top plate to be moved and disassembled as a whole, without the need to disassemble them one by one, which improves the convenience of disassembly and cleaning. It solves the problem that when the stamping machine used for the heat sink of the existing automotive LED headlights is installed, most of them are directly fixed with bolts, which easily leads to the misalignment of the upper and lower mold bases, resulting in poor stamping and forming effect. In addition, when installing the upper mold base, the upper mold base lacks support and is easy to fall, which leads to the inconvenience of installation.

[0013] (2) By setting a slot on the upper surface of the base at the same vertical and horizontal position as the moving groove, the positioning plate can be inserted into the slot when adjusting the height of the lower mold base and the upper mold base, so as to avoid the upper mold base being blocked from moving down.
