Description

Technical Field

[0001] The utility model relates to a mold, and in particular to a universal numerical control mold. Background Art

[0002] At present, a Chinese patent with the publication number CN214601709U discloses a forging mold, which includes a bottom plate, a lower mold arranged at the upper end of the bottom plate, and an upper mold arranged above the lower mold. A forging cavity is formed between the upper mold and the lower mold. During use, the heated blank is placed in the lower mold, and the blank is extruded downward by the upper mold so that the blank is forged and formed. However, since the shape of the forging cavity of the above forging mold is fixed, it can only be used to process products with a specific shape, and has the defect of low applicability. Summary of the Invention

[0003] In view of this, the purpose of the utility model is to provide a universal numerical control mold, which has the advantage of high applicability.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a universal numerical control mold, including a lower mold with a forming cavity opened at the upper end, and a number of forging support units evenly arranged inside the forming cavity. The forging support unit includes a lifting drive mechanism and a forging support head arranged above the lifting drive mechanism. The output end of the lifting drive mechanism is connected to the lower end of the forging support head, and the lifting drive mechanism is used to drive the forging support head to slide up and down in the forming cavity.

[0005] Through the above technical solution, during use, according to the shape of the workpiece to be processed and through the controller connected to the above numerical control mold, the operating state of the lifting drive mechanism can be controlled to change the height of each forging support head. The above-set numerical control mold can be adapted to workpieces of various shapes, even workpieces with complex curved surface shapes, and has the advantage of high applicability.

[0006] Preferably, the forging support head includes a first forging support seat and a forging support ball ball-jointed at the upper end of the first forging support seat.

[0007] Through the above technical solution, the forging support ball ball-jointed at the upper end of the first forging support seat can not only be used to support the blank, but also reduce the difficulty of taking out the blank after it is formed.

[0008] When processing a blank that can be deformed under the influence of its own gravity, such as heated and softened glass material, it only needs to place the blank above a number of forging support balls. When processing a blank that cannot be deformed under the influence of its own gravity, such as a heated stainless steel plate, it is necessary to lay a rubber pad on the upper ends of a number of forging support balls, and then place the blank above the rubber pad for forging.

[0009] Preferably, the forging support head includes a second forging support seat, a connecting sphere ball-jointed at the upper end of the second forging support seat, a forging support plate arranged at the upper end of the connecting sphere, and a support sphere arranged at the upper end of the forging support plate.

[0010] Through the above technical solution, when two adjacent forging support plates touch each other, the corresponding two support spheres can be limited to achieve the purpose of restricting the swing angle of the support spheres.

[0011] Preferably, rounded corners are provided at the upper end corners of the forging support plate.

[0012] Through the above technical solution, rounded corners are provided on the upper surface of the forging support plate, making the transition between the forging support plates smoother and not easily affecting the processing of the workpiece.

[0013] Preferably, the lifting drive mechanism includes a drive motor, a drive lead screw connected to the output end of the drive motor through a coupling, and a lead screw sleeve threadedly connected to the upper end of the drive lead screw. The forging support head is rotatably connected to the upper end of the lead screw sleeve.

[0014] Through the above technical solution, during use, the drive motor drives the drive lead screw to rotate circumferentially through the coupling, thereby controlling the up and down movement of the lead screw sleeve and the forging support head.

[0015] Preferably, a connecting shaft is arranged at the lower end of the forging support head, and the forging support head is rotatably connected to the upper end of the lead screw sleeve through the connecting shaft.

[0016] Through the above technical solution, the forging support head is rotatably connected to the lead screw sleeve through a coupling, which has the advantage of being relatively convenient for disassembly and assembly.

[0017] Preferably, a positioning platform is arranged in the forming chamber. The drive lead screw penetrates through the positioning platform and is rotatably connected to the positioning platform.

[0018] Through the above technical solution, the positioning platform can support and limit the lower end of the drive lead screw to prevent the lower end of the drive lead screw from shaking or shifting.

[0019] Preferably, a retaining ring is arranged on the outer side of the drive lead screw. The retaining ring is located above the positioning platform. A bearing is sleeved on the outer side of the drive lead screw, and the upper and lower ends of the bearing respectively abut against the retaining ring and the positioning platform.

[0020] Through the above technical solution, by arranging a bearing between the retaining ring and the positioning platform, the rotation of the drive lead screw can be made smoother, and the wear of the drive lead screw can be effectively reduced. Description of the Drawings
