Description

Technical Field

[0001] This utility model relates to the field of clamping components, specifically a clamping component for an adjustable die-casting mold. Background Technology

[0002] The clamping assembly used on die-casting molds consists of a base, a lead screw, clamping plates, and the die-casting mold itself. The die-casting mold is placed on top of the clamping table, with the mold's base plate in contact with the table. A drive mechanism (such as a hydraulic push rod or motor) rotates the lead screw, which is connected to the clamping plates via a threaded connection or other transmission method. The rotation of the lead screw causes the clamping plates to move axially along the lead screw. When the lifting plate moves downward, it applies tension to multiple connecting plates simultaneously. The two ends of each connecting plate are connected to corresponding moving blocks and lifting plates. The moving blocks are fixedly connected to push plates, thus driving the corresponding push plates to move synchronously towards the center of the clamping table. During the movement of the clamping plates, they contact the outer wall of the die-casting mold and gradually apply pressure, clamping the mold. This clamping process acts as a buffer and assists in resetting, while also ensuring sufficient contact between the clamping plates and the mold surface, improving the clamping effect.

[0003] Existing patent application CN218946309U discloses a positioning and clamping mechanism for a die-casting mold, comprising a positioning component. The positioning component includes a connecting plate, a first cavity, a square rod, a toothed plate, a rotating rod, a first gear, a second gear, a pin, a third gear, a knob, a rectangular block, and a fixing plate. Two connecting plates are provided, each with a first cavity. A square rod is welded between the inner walls of the two sides of the first cavity, and a toothed plate is slidably connected to the square rod. This invention clamps the die-casting mold using the connecting plate. The knob drives the third gear to rotate via the pin, which in turn drives the rotating rod to rotate via the second gear. The rotating rod then drives the toothed plate to move via the first gear. The toothed plate slides on the square rod, and the rectangular block drives the fixing plate to move, thus clamping and fixing the top of the die-casting mold. This improves the stability of the die-casting mold during processing, prevents mold displacement, and increases work efficiency.

[0004] However, in the above-mentioned method of clamping the die-casting mold with a connecting plate, the threaded sleeve on the clamping plate will continuously rub against the lead screw during long-term movement and clamping. During the friction process, the original lubricating grease will be consumed or destroyed. After the lubrication is lost, the frictional resistance increases sharply, which can lead to jamming. When the clamping plate clamps the die-casting mold, it will be in direct contact with the die-casting mold, which will cause frictional damage between the die-casting mold and the clamping plate. In addition, the mounting port of the die-casting mold needs to be lubricated during installation. Therefore, an adjustable clamping component for die-casting molds needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamping assembly for an adjustable die-casting mold to solve the problems mentioned in the background art.
