There is a deviation in the position of the mold core, and it cannot be accurately placed horizontally in the middle of the mold. It is easy to deflect to one side, which causes severe wear on the side wall of the mold core installation area during subsequent installation actions, making it impossible to reuse.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Embodiment 1, as Figure 1 , 2As shown, a diamond wire drawing die assembly and disassembly machine comprises: a frame 100, wherein an assembly and disassembly component and a die sleeve installation component are installed on the frame 100, and the die sleeve installation component is suitable for installing the die sleeve and is installed at the bottom of the frame 100.

[0029] The assembly and disassembly components include a vertical frame 10 and a driver 20 that drives the vertical frame 10 to move up and down. The driver 20 is installed on the top of the frame 100. The driver 20 is preferably a hydraulic cylinder. The vertical frame 10 is vertically slidably arranged on the frame 100 and vertically slidably cooperates with the vertical guide rail 101. The vertical frame 10 as a whole is an inverted U-shaped structure.

[0030] The clamping mold assembly includes a clamping unit 1 30 and a clamping unit 2 40 installed on a vertical frame 10. The clamping unit 1 30 and the clamping unit 2 40 are relatively distributed and the movement directions of the clamping unit 1 30 and the clamping unit 2 40 are opposite. The clamping unit 1 30 and the clamping unit 2 40 are suitable for horizontally clamping the mold core together up and down.

[0031] The mold core is fixed horizontally by clamping up and down by clamping unit 1 30 and clamping unit 2 40, wherein the clamping unit 40 can freely pass through the installation area of ​​the mold core on the mold sleeve during the clamping process, and the horizontal position of the mold core is corrected before being installed in the mold sleeve. After the correction, the coaxiality of the mold sleeve and the mold core can be ensured, and the side wall of the mold core installation area of ​​the mold sleeve can be prevented from being severely worn when the mold core is crimped in the mold sleeve, which makes it impossible to reuse the mold sleeve when it is reused later.

[0032] Finally, the driver 20 drives the vertical frame 10 to move down a distance H, thereby pressing the horizontally clamped mold core into the mold sleeve.

[0033] When removing the mold core, the driver 20 drives the vertical frame 10 to move down a distance H, the clamping unit 1 30 and the clamping unit 2 40 approach each other to clamp the mold core up and down first, and the driver 20 drives the vertical frame 10 to move up a distance H, the mold core is removed, the clamping unit 1 30 and the clamping unit 2 40 move away from each other, the mold core is separated, the mold core is removed, and a new mold core is placed at the upper opening of the mold core installation area in the mold sleeve.

[0034] Embodiment 2, in embodiment 1:

[0035] like Figure 1 , 2 As shown, the clamping unit 1 30 includes a moving frame 1 31, which moves vertically relative to the vertical frame 10, and a top clamping structure is installed on the moving frame 1 31;

[0036] The second clamping unit 40 includes a second moving frame 32 , which moves vertically relative to the vertical frame 10 , and a bottom clamping structure is installed on the second moving frame 32 .

[0037] like Figure 2 As shown, the top clamping structure and the bottom clamping structure both include a push rod 50, on which a positioning plate 51 and a centering body 52 are mounted. The positioning plate 51 is suitable for flatly fitting the corresponding end face on the mold core, and the centering body 52 is suitable for being inserted into the drawing hole of the mold core. The centering body 52 is made of a flexible material, and the flexible material is rubber or polyurethane foam.

[0038] During the clamping process, the centering body 52 will enter the drawing hole of the mold core to center the top and bottom of the mold core. Then, as the clamping action continues, the two positioning plates 51 will be used to horizontally calibrate the corresponding end faces on the mold core, and finally complete the horizontal clamping and fixing.

[0039] Embodiment 3, in one of the above embodiments, in order to realize that the clamping unit 1 30 and the clamping unit 2 40 simultaneously move in opposite directions, as shown in FIG. Figure 1 , 2 As shown, the clamping assembly also includes a driving motor 11 installed on the vertical frame 10, and a bidirectional lead screw 12 rotatably installed on the vertical frame 10. The output end of the driving motor 11 is connected to the bidirectional lead screw 12 via a coupling, and the bidirectional lead screw 12 is threadedly matched with the moving frame 1 31 and the moving frame 2 32.

[0040] Slides 70 are provided at both ends of the movable frame 1 31 and the movable frame 2 32 . The two groups of slides 70 are threadedly matched and installed on the bidirectional screw 12 , and the movement directions of the two groups of slides 70 are opposite. The vertical frame 10 is vertically provided with slide grooves suitable for the movement of the slides 70 .

[0041] The bidirectional lead screw 12 is driven to rotate by the driving motor 11, so that the slide seats 70 at both ends of the moving frame 1 31 and the moving frame 2 32 are moved closer to each other (clamping / calibrating the mold core) or farther away from each other (releasing the mold core).

[0042] Embodiment 4, in embodiment 3:

[0043] like Figure 1 , 2 As shown in Figures 4 and 5, the die sleeve installation assembly includes a hydraulic cylinder 80 and a pressure plate 90 installed at the end of the piston rod of the hydraulic cylinder 80. A bull's eye bearing 91 is provided on the side of the pressure plate 90 facing the die sleeve. The pressure plate 90 is pressed down by the recovery of the piston rod of the hydraulic cylinder 80, and the top surface of the die sleeve is pressed downward through the bull's eye bearing 91. A hole is provided on the top of the pressure plate 90 for the positioning plate 51 to pass through.

[0044] like Figure 3 , 5As shown, the bottom clamping structure also includes a correction disk 60 at the bottom of the positioning disk 51, and a circumferentially arranged guide groove 61 is provided on the correction disk 60. The guide groove 61 is a T-shaped groove, and the side opening of the guide groove 61 extends to the outer peripheral surface of the correction disk 60. There are at least three groups of guide grooves 61, which are arranged along the radial direction. A spring 63 and a correction body 62 are installed in the guide groove 61. The correction body 62 is slidably arranged in the guide groove 61, and the spring 63 is installed on the side of the correction body 62 close to the center of the correction disk 60.

[0045] When clamping the mold core before installing it, the correction body 62 of the bottom clamping structure touches the mold sleeve before the positioning plate 51 fits the lower end surface of the mold core. The mold sleeve is adaptively corrected in position through the correction body 62 and the spring 63 to ensure the coaxiality of the mold sleeve and the mold core.

[0046] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
