Description

Technical Field

[0001] The present application relates to the technical field of mold processing, and in particular to a clamping structure for mold processing. Background Art

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. To make and process molds, more mechanical equipment is required than that used for general product processing. For example, in addition to general turning, milling, cutting, grinding, and clamping, there are also wire cutting, CNC milling machines or machining centers, electric sparks, etc. Usually, the mold consists of an upper mold and a lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold is obtained or the corresponding waste is removed. Mold processing processes include: cutting molds, blanking molds, compound molds, extrusion molds, four-slide molds, progressive molds, stamping molds, die-cutting molds, etc. At present, when processing molds, the molds are usually clamped by bolting the clamps, so that the position of the mold can be fixed to facilitate the corresponding processing, but this clamping structure is relatively simple and fixed, and it is difficult to flexibly adjust the corresponding clamping position according to the size of the mold, so the applicability is low.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a clamping structure for mold processing. Figure 1-Figure 3 , including a clamping seat 1, a mounting frame 13 is connected to the center of the top of the inner wall of the clamping seat 1 by screws for easy installation, a bidirectional motor 14 is installed inside the mounting frame 13, the output end of the bidirectional motor 14 passes through the inner walls on both sides of the mounting frame 13 and is connected to a transmission shaft 15 for providing working power on both sides, a clamping structure is provided inside the clamping seat 1, the clamping structure includes a top tooth plate 8, a bottom tooth plate 9 and a gear 16, and one end of the transmission shaft 15 away from the mounting frame 13 is fixedly connected to the gear 16, and the transmission shaft 15 can be driven to rotate by the operation of the bidirectional motor 14, and then the gear 16 can be driven to rotate and work.

[0020] A group of positioning slide bars 7 are symmetrically fixed at both ends of the clamping base 1. The positioning slide bars 7 are slidably connected to the top tooth plate 8 and the bottom tooth plate 9, and the ends of the top tooth plate 8 and the bottom tooth plate 9 that are close to each other are fixed with tooth blocks 17 that mesh with the gear 16. As the gear 16 rotates, it can mesh with the tooth block 17, thereby driving the top tooth plate 8 and the bottom tooth plate 9 to slide closer to or away from each other outside the positioning slide bars 7, thereby being able to flexibly adjust the distance of the mold clamping.

[0021] Combination Figure 1-Figure 2 A first connecting push rod 6 is symmetrically and movably provided at the bottom of the outer wall of the clamp seat 1, and an outer push plate 4 is fixedly provided at one end of the first connecting push rod 6. A second connecting push rod 12 is symmetrically and movably provided at the top of the outer wall of the clamp seat 1, and a connecting plate 2 is fixedly provided at one end of the second connecting push rod 12. The bottom of the connecting plate 2 is an integral structure with an inner push plate 3 fixed thereon, and the outer push plate 4 is located on the outside of the inner push plate 3. The mold to be processed can be placed between the outer push plate 4 and the inner push plate 3, thereby forming a clamping force on both sides of the mold.

[0022] In order to flexibly adjust the clamping distance, specifically, since one end of the second connecting push rod 12 extends into the clamp seat 1 and is fixedly connected to the outer wall of the top tooth plate 8, both ends of one side of the bottom tooth plate 9 are welded with fixed blocks 10, and one end of the first connecting push rod 6 extends into the clamp seat 1 and is fixedly connected to the fixed block 10. Therefore, as the top tooth plate 8 and the bottom tooth plate 9 move, the second connecting push rod 12 and the first connecting push rod 6 can respectively pull the outer push plate 4 and the inner push plate 3 to produce corresponding movements, and can be tightly and firmly attached to both sides of the mold.

[0023] Balance sliders 11 are symmetrically welded on both sides of the bottom of the inner push plate 3. The balance slider 11 is slidably connected to the first connecting push rod 6 to position the inner push plate 3 to avoid deviation during the adjustment process. Buffer springs 5 ​​for support are connected between the first connecting push rod 6 and the second connecting push rod 12 and the outer wall of the clamp seat 1 to prevent hard collisions and provide strong protection.

[0024] The implementation principle of a clamping structure for mold processing in an embodiment of the present application is as follows: when in use, the mold to be processed is placed between the inner push plate 3 and the outer push plate 4, and then the bidirectional motor 14 is started to work and the two gears 16 are driven to rotate via the transmission shaft 15. The gears 16 rotate and engage with the two sets of tooth blocks 17, thereby pushing the top tooth plate 8 and the bottom tooth plate 9 to slide closer or farther on the outer wall of the positioning slide bar 7. With the movement of the top tooth plate 8 and the bottom tooth plate 9, the second connecting push rod 12 and the first connecting push rod 6 can be pulled to slide a corresponding distance inside the clamp seat 1 at the same time. At this time, the buffer spring 5 is compressed and buffered to avoid rigid collision, thereby making the inner push plate 3 and the outer push plate 4 close to the outer wall of the mold to clamp and position. At this time, the balancing slider 11 cooperates with the sliding support outside the first connecting push rod 6 to stabilize the position of the mold and facilitate subsequent processing.
