[0002] A mold is a tool used to make molded objects. This tool is composed of various workpieces. Different molds are composed of different workpieces. The mold needs to be punched during the production process.

[0003] The utility model patent application number CN202221268319.9 (publication number CN217452222U) discloses a mold processing and punching device, comprising a processing table and a mounting plate. The mounting plate is provided on the top rear side of the processing table, a drilling mechanism is provided on the top of the mounting table, and a moving mechanism is provided on the top of the processing table. The left and right transmission ends of the moving mechanism are symmetrically connected to the moving plate in a sliding manner, and the upper parts of the left and right moving plates are symmetrically connected to the positioning mechanism in a rotating manner.

[0004] The above patent clamps and positions the left and right ends of the shaft-like workpiece in the radial direction by manually tightening the locking screws. However, the four locking screws on one side are not convenient for centering during the screwing process, which will cause the shaft workpiece to tilt and the center of the circle at both ends to shift, resulting in deviation in the drilling position. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a drilling machine for mold processing, which is used to solve the technical problem that the existing drilling device for shaft workpieces is not convenient for centering, causing the shaft workpiece to tilt and the center of the circle at both ends to shift, resulting in deviation in the drilling position.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a drilling machine for mold processing, comprising a processing table and a mounting plate located on the processing table, a drilling mechanism being provided on the top of the mounting plate, a moving mechanism being provided on the top of the processing table, and moving plates being symmetrically slidably connected to the left and right sides of the moving mechanism, wherein gear plates are rotatably connected to the moving plates;

[0009] The rotating column is rotatably connected to the gear plate, the sliding column is slidably connected to the gear plate, and a clamping rod abutting against the circumferential surface of the shaft workpiece is fixedly mounted on the sliding column.

[0010] On the basis of the above technical solution, the mold processing drilling machine of the present invention can also be improved as follows:

[0011] Furthermore, a rotating plate concentric with the gear plate is provided on the side of the adjustment component away from the gear plate, and three arc-shaped sliding grooves are opened on the rotating plate. The sliding grooves are distributed in a circular array on the rotating plate, and each of the sliding grooves is slidably connected to a clamping rod.

[0012] Furthermore, a driving rod extending toward the gear plate is fixedly mounted in the middle of the rotating plate, a driving motor B is fixedly mounted in the middle of the gear plate, and an output shaft of the driving motor B is connected to the driving rod via a coupling.

[0013] Furthermore, a through slot is provided on the movable plate, a rotating slot is provided in the middle of the through slot, the gear plate is rotatably connected in the rotating slot, a driving slot is provided above the rotating slot, and the driving slot is communicated with the rotating slot.

[0017] Compared with the prior art, the beneficial effects of the mold processing drilling machine provided by the utility model are:

[0018] By setting up an adjustment component, the clamping rods can be moved simultaneously under the action of the rotating plate. The circle formed by the three clamping rods on the same side is always concentric with the center of the gear plate and the rotating plate. The clamping rods can clamp shaft workpieces of different diameters, and the centers of the two ends of the shaft workpiece are collinear, avoiding the situation where the clamping of the shaft workpiece is tilted, resulting in an offset in the punching position.

[0034] like Figure 1-6 As shown, the utility model provides a drilling machine for mold processing, comprising a processing table 1 and a mounting plate 6 located on the processing table 1, a drilling mechanism 61 is provided on the top of the mounting plate 6, a moving mechanism 4 is provided on the top of the processing table 1, and a moving plate 2 is symmetrically slidably connected to the left and right sides of the moving mechanism 4, wherein a gear plate 21 is rotatably connected to each of the moving plates 2;

[0035] On the side where the gear plates 21 on both sides are close to each other, there are three sets of adjustment components, which include a rotating column 22, a sliding column 23 and a connecting rod 24. The two ends of the connecting rod 24 are fixedly connected to the rotating column 22 and the sliding column 23 respectively;

[0036] The rotating column 22 is rotatably connected to the gear plate 21 , the sliding column 23 is slidably connected to the gear plate 21 , and a clamping rod 25 abutting against the circumferential surface of the shaft workpiece is fixedly mounted on the sliding column 23 .

[0037] Optionally, in the above technical solution, a rotating plate 31 concentric with the gear plate 21 is provided on the side of the adjustment component away from the gear plate 21, and three arc-shaped sliding grooves 32 are provided on the rotating plate 31. The sliding grooves 32 are distributed in a circular array on the rotating plate 31, and a clamping rod 25 is slidably connected in each sliding groove 32.

[0038] Optionally, in the above technical solution, a driving rod 33 extending toward the gear plate 21 is fixedly installed in the middle of the rotating plate 31, and a driving motor B34 is fixedly installed in the middle of the gear plate 21. The output shaft of the driving motor B34 is connected to the driving rod 33 through a coupling.

[0039] Optionally, in the above technical solution, a through slot 20 is provided on the movable plate 2, a rotating slot 201 is provided in the middle of the through slot 20, the gear plate 21 is rotatably connected in the rotating slot 201, a driving slot 27 is provided above the rotating slot 201, and the driving slot 27 is connected to the rotating slot 201.

[0040] Optionally, in the above technical solution, a driving gear 28 is rotatably connected in the driving groove 27, the driving gear 28 is meshed with the gear plate 21, and a driving motor A26 is fixedly installed on the outer wall of the movable plate 2, and the output shaft of the driving motor A26 is connected to the middle part of the driving gear 28 through a coupling.

[0041] Optionally, in the above technical solution, a hollow horizontal plate 5 is fixedly installed on the rear side of the processing table 1, a slide groove 50 is provided on the top wall of the horizontal plate 5, and a drive motor C51 is fixedly installed on the right inner wall of the horizontal plate 5. The output shaft of the drive motor C51 extends to the left, and the end is connected to one end of a screw 52 through a coupling, and the other end of the screw 52 is rotatably connected to the side inner wall of the horizontal plate 5.

[0042] Optionally, in the above technical solution, a screw block 53 is sleeved on the screw rod 52 and threadedly connected thereto, the screw block 53 is slidingly connected to the slide groove 50, and a mounting plate 6 is fixedly installed on the top wall of the screw block 53, and the mounting plate 6 is slidingly connected to the top wall of the movable plate 2.

[0043] Furthermore, the drilling mechanism 61 includes a telescopic cylinder 62 and a drilling machine 63 . The fixed end of the telescopic cylinder 62 is fixedly mounted on the top of the mounting plate 6 . The piston rod of the telescopic cylinder 62 extends downward, and the end is fixedly connected to the drilling machine 63 .

[0044] Furthermore, the moving mechanism 4 includes a two-way cylinder 41 and a slide rail 42. The two-way cylinder 41 is fixedly installed in the middle of the top of the processing table 1. The left and right piston ends of the two-way cylinder 41 are connected to the moving plate 2. The top of the processing table 1 is symmetrically fixed with slide rails 42 on the front and back sides of the two-way cylinder 41, and the moving plate 2 is slidably connected to the slide rails 42.

[0045] The connection lines between the three rotating posts 22 on the same side and the connection lines between the three sliding posts 23 form an equilateral triangle.

[0046] The output shaft of the driving motor A26 passes through the side wall of the moving plate 2 and is rotationally connected thereto.

[0047] Among them, when the three clamping rods 25 are all located at the outer end of the sliding groove 32, the inscribed circle formed is the maximum workpiece diameter (this state is the initial position); when the three clamping rods 25 are all located at the inner end of the sliding groove 32, the inscribed circle formed is the minimum workpiece diameter.

[0048] When in use, the bidirectional cylinder 41 is activated to retract its movable end, driving the left and right movable plates 2 to move closer to each other along the slide rail 42, firstly so that both ends of the shaft workpiece can partially correspond to the clamping rod 25;

[0049] The drive motor B34 is started to rotate the rotating plate 31 clockwise via the drive rod 33. The rotation of the rotating plate 31 causes the clamping rods 25 to slide along the sliding grooves 32, and the clamping rods 25 on the same side move closer to each other (i.e., the diameter of the circle formed by the clamping rods 25 gradually decreases).

[0050] Until the clamping rods 25 are in contact with the circumferential surface of the shaft workpiece, the shaft workpiece is positioned in the radial direction to prevent the shaft pipe fitting from being skewed. At this time, the two end faces of the shaft workpiece are parallel to the vertical surface of the movable plate 2 (also parallel to the vertical surface of the rotating plate 31), that is, the cross section of the shaft workpiece is in a horizontal state, and the two-way cylinder 41 is started again to retract its movable end, driving the left and right movable plates 2 to approach each other along the slide rail 42 until the two rotating plates 31 are in contact with the two ends of the shaft workpiece at the same time, and the two ends of the shaft workpiece are axially clamped by the rotating plate 31 (wherein, the clamping principle of the shaft workpiece driven by the two-way cylinder 41 is equivalent to the clamping principle of a bench vise), and the drilling mechanism 61 is started to drill the circumferential wall of the shaft workpiece;

[0051] The drive motor A26 is started to make its output shaft drive the driving gear 28 to rotate in place, which can make the gear plate 21 drive the shaft workpiece clamped by the clamping rod 25 to rotate under the action of meshing connection, thereby realizing the rotary drilling work on the circumferential wall of the shaft workpiece;

[0052] Start the drive motor C51 so that its output shaft drives the screw 52 to rotate in place. The rotation of the screw 52 causes the screw block 53 threadedly connected to it to move horizontally, thereby driving the mounting plate 6 to slide on the horizontal plate 5 (the width of the vertical plate of the mounting plate 6 is greater than the width of the slide groove 50), and adjusting the position of the drilling mechanism 61 on the mounting plate 6, thereby realizing the adjustment of the position of the hole on the shaft of the shaft workpiece.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
