Description
An auxiliary clamping mechanism for die casting of aluminum-magnesium alloy Technical Field
[0001] This utility model relates to the technical field of auxiliary clamping mechanisms for die casting of aluminum-magnesium alloys, and in particular to an auxiliary clamping mechanism for die casting of aluminum-magnesium alloys. Background Technology
[0002] In the die-casting production of aluminum-magnesium alloys, precise and stable clamping is a crucial step in ensuring product quality. Aluminum-magnesium alloys are widely used in many fields due to their excellent properties; however, the die-casting process places stringent requirements on the clamping mechanism. Traditional clamping mechanisms for aluminum-magnesium alloy die casting have several drawbacks. First, the clamping force is difficult to control precisely. It cannot provide the right clamping force for aluminum-magnesium alloy die-casting molds and workpieces of different shapes and sizes. Insufficient clamping force can easily cause displacement of the mold or workpiece during die casting, leading to defects such as dimensional deviations and flash. Excessive clamping force may damage the mold or workpiece, increasing the scrap rate and production costs. Second, traditional clamping mechanisms lack flexibility and cannot quickly adapt to diverse die-casting needs. In actual production, molds often need to be changed frequently. Traditional mechanisms are time-consuming and labor-intensive in adjusting clamping positions and angles, which seriously affects production efficiency. Traditional mechanisms lack effective limiting measures, and vibrations during the die casting process may cause the mold or workpiece to deviate from the predetermined position, further affecting product quality and even potentially causing safety accidents. Based on this, an auxiliary clamping mechanism for aluminum-magnesium alloy die casting is proposed to solve the above problems. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary clamping mechanism for die casting of aluminum-magnesium alloys. This mechanism solves the problems of mold or workpiece displacement during die casting, which can lead to dimensional deviations and flash defects in the castings. Furthermore, excessive clamping force can damage the mold or workpiece, increasing scrap rates and production costs. Secondly, traditional clamping mechanisms lack flexibility and struggle to quickly adapt to diverse die casting requirements. In actual production, frequent mold changes are often necessary. Adjusting the clamping position and angle using traditional mechanisms is time-consuming and labor-intensive, severely impacting production efficiency. Traditional mechanisms also lack effective limiting measures, allowing vibrations during die casting to cause the mold or workpiece to deviate from its intended position, further affecting product quality and potentially leading to safety accidents.

Embodiments
[0023] During die casting, the mold or workpiece is prone to displacement, leading to defects such as dimensional deviations and flash in the casting. Excessive clamping force can damage the mold or workpiece, increasing scrap rates and production costs. Secondly, traditional clamping mechanisms lack flexibility and struggle to quickly adapt to diverse die casting needs. In actual production, frequent mold changes are often necessary. Traditional mechanisms are time-consuming and labor-intensive in adjusting clamping positions and angles, severely impacting production efficiency. Furthermore, traditional mechanisms lack effective limiting measures, and vibrations during die casting can cause the mold or workpiece to deviate from its intended position, further affecting product quality and potentially leading to safety accidents. This embodiment provides an auxiliary clamping mechanism for aluminum-magnesium alloy die casting.

The fixed base frame 1 is equipped with a connecting mechanism 2, which includes connecting components 21 disposed on both sides of the fixed base frame 1. A clamping component 22 is disposed in the middle section of the fixed base frame 1. A limiting component 23 is provided at the bottom of the middle section; the clamping component 22 includes a sliding block 221 that is slidably connected to the inner wall of the limiting groove opened at the front and rear ends of the fixed base frame 1.

When it is necessary to clamp the die-casting mold or workpiece, rotating the adjusting screw 224 moves the guide rod 225, thereby driving the moving block 229 and the clamping plate 2210 fixedly connected to the bottom to approach the mold or workpiece. After contacting the mold or workpiece, the connecting spring 228 further plays its role, automatically adjusting the pressure of the clamping plate 2210 according to the shape of the mold or workpiece to achieve precise and flexible clamping. At the same time, this design can avoid damage to the mold or workpiece due to excessive clamping force, improving the safety and reliability of clamping.
