Molds are used in forging, stamping, powder metallurgy pressing, pressure casting, and compression and injection molding of products such as engineering plastics, rubber, and ceramics. Molds are generally divided into two parts: a movable mold and a fixed mold based on their motion state; and a concave mold and a convex mold based on their shape. Molds can be made of steel, iron, tin, wood, plaster, and clay, with steel being the most commonly used.

[0003] During the mold manufacturing process, it is usually necessary to use a drilling machine to drill holes in the mold. Among them, a drilling machine refers to a machine tool that mainly uses a drill bit to process holes on the workpiece. It is also the most common general-purpose machine tool. When in use, the drill bit rotation is usually the main movement, and the drill bit axial movement is the feed movement. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand holes, ream holes or perform tapping and other processing. During the drilling process, the workpiece does not move, the tool moves, the tool center is aligned with the hole center, and the tool rotates (main motion); drilling machines are indispensable equipment in mechanical manufacturing and various repair factories, mainly including vertical drilling machines, bench drilling machines, radial drilling machines, deep hole drilling machines, center hole drilling machines, milling drilling machines, horizontal drilling machines, etc. Among them, the spindle of the vertical drilling machine is arranged vertically and the center position is fixed. It is suitable for processing holes in medium and small workpieces. The workbench and spindle box can be adjusted along the column guide rail to accommodate workpieces of different heights. The vertical drilling machine has a relatively simple structure and is easy to maintain. The vertical drilling machine also has the advantages of high precision, suitable for processing various holes, and easy operation.

When the rotating gear plate 51 rotates, it can drive the telescopic rod 52 to rotate, and the telescopic rod 52 drives the rotating sleeve 421 to rotate, thereby realizing the rotation of the cutting frame 42. At this time, the rotating sleeve 421 drives the cutting knife 422 to rotate, and the rotation direction of the cutting knife 422 is opposite to the rotation direction of the movable sleeve 432. When the movable sleeve 432 drives the cutting chips to move to the cutting knife 422, the cutting knife 422 can cut off the cutting chips.

[0043] The working principle of the drilling device for mold manufacturing of the present invention is as follows: when drilling a workpiece, the workpiece is first mounted on a clamping table, and then the drilling mechanism 2 is started to drive the drill 3 to descend toward the workpiece. At the same time, the driving member 21 is started, and the output shaft of the driving member 21 drives the drill 3 to rotate. When the drill 3 rotates, the linkage plate 433 is driven to rotate, and the linkage plate 433 drives the movable sleeve 432 to rotate. When the driving member 21 rotates, the output shaft of the driving member 21 drives the drill 3 to rotate, and at the same time drives the linkage sleeve 621 to rotate, drives the linkage gear plate 622 to rotate, drives the rotating gear 632 and the rotating rod 631 to rotate, and the rotating gear 632 drives the rotating gear plate 51 to rotate. The rotation direction of the rotating gear plate 51 is opposite to the rotation direction of the drill 3. When the rotating gear plate 51 rotates, it drives the telescopic rod 52 to rotate, the telescopic rod 52 drives the rotating sleeve 421 to rotate, and the rotating sleeve 421 drives the cutting knife 422 to rotate. The rotation direction of the cutting knife 422 is opposite to the rotation direction of the movable sleeve 432. The drill bit 3 then descends and rotates to drill the workpiece. During the drilling process, cutting chips are generated. As the workpiece is further processed, the cutting chips extend upward and move along the guide slope 431. The movable sleeve 432 drives the cutting chips to move. At the same time, the cutting knife 422 can cut the cutting chips. The cut cutting chips can enter the storage chamber, pass through the discharge hole into the fixed frame 41, and then be discharged from the pipeline. At the same time, during the drilling process, cutting fluid is added to the liquid supply pipe 11. After passing through the liquid storage chamber 411, the cutting fluid is transported to the liquid supply hole 412, sprayed out through the liquid supply hole 412, and used. The used cutting fluid can flow into the storage chamber from the top of the rotating sleeve 421 near one end of the drill bit 3, and enter the fixed frame 41 through the discharge hole, and finally discharged through the waste pipe 10. The workpiece is then processed further, and after the processing is completed, the workpiece is removed from the clamping table to complete the drilling operation on the workpiece.

[0044] By setting the cutting device 4, when the drill 3 is drilling the workpiece, the inner wall of the guide frame 43 abuts against the spiral groove of the drill 3, and the cutting frame 42 rotates and cooperates with the fixed frame 41, so that when the drill 3 rotates, it can drive the guide frame 43 to rotate synchronously on the fixed frame 41. When the drill 3 generates chips during drilling, and the chips gradually become longer during the drilling process, the top of the chips can move along the guide frame 43 and move toward the cutting frame 42 along the guide inclined surface 431. Since the cutting frame 42 is located outside the guide frame 43 and the cutting frame 42 rotates in the opposite direction to the cutting frame 42 when the drill 3 rotates, when the guide frame 43 drives the chips to move to the cutting frame 42, the rotating cutting frame 42 can cut off the chips, which can reduce the friction between the chips and the surface of the workpiece and the damage to the workpiece surface, thereby improving the drilling quality of the workpiece.
