[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0030] Such as Figures 1 - 5As shown in the figure, the utility model provides a mold base with a shock-proof structure, which includes an upper mold base 1. A lower mold base 2 is installed on the surface of the upper mold base 1. A base 3 is installed on the surface of the lower mold base 2. A bottom plate 4 is installed on the surface of the base 3. A shock-absorbing device 5 is provided on the surface of the bottom plate 4.

[0031] Next, specifically describe the specific setting and function of its shock-absorbing device 5.

[0032] As Figure 2 and Figure 5As shown, the shock absorber 5 includes two limit rods 501, both of the two limit rods 501 are fixedly connected to the bottom plate 4. A screw rod 502 is threadedly connected to the surface of the limit rod 501. A clamping groove 503 is threadedly connected to the arc surface of the screw rod 502. The clamping groove 503 is clamped with the limit rod 501. A buffer plate 504 is fixedly connected to the surface of the clamping groove 503. Four damping rods 505 are fixedly connected to the surface of the buffer plate 504. A square plate 507 is fixedly connected to the surfaces of the four damping rods 505. A spring 506 is sleeved on the arc surface of the damping rod 505. Two ends of the spring 506 are respectively fixedly connected to the buffer plate 504 and the square plate 507. Two fixing plates 508 are fixedly connected to the surface of the square plate 507. A lead screw 509 is threadedly connected to the surfaces of the two fixing plates 508. One end of the lead screw 509 is rotatably connected to an abutting block 510. The abutting block 510 abuts against the base 3. The fixing plate 508, the lead screw 509 and the abutting block 510 can be used to limit the base 3 to prevent misalignment when installing the lower die holder 2 and the upper die holder 1. An expansion rod 511 is fixedly connected to the surface of the abutting block 510. The other end of the expansion rod 511 is fixedly connected to the fixing plate 508. The abutting block 510 will drive one end of the expansion rod 511 to move. At this time, the expansion rod 511 can prevent the abutting block 510 from rotating as the lead screw 509 rotates. A turning handle 512 is fixedly connected to one end of the lead screw 509. The vertical section of the turning handle 512 is cross-shaped. Rotating the turning handle 512, at this time the turning handle 512 will drive the lead screw 509 to move along the surface of the fixing plate 508. At the same time, the lead screw 509 will move in the direction close to the base 3 by virtue of its own thread. At this time, the turning handle 512 can facilitate the rotation of the lead screw 509. A protective plate 513 is fixedly connected to the surface of the buffer plate 504. The protective plate 513 is a rubber plate. The bump 514 will transmit the received force to the protective plate 513. At this time, the protective plate 513 made of rubber can protect the bottom plate 4. A number of bumps 514 are fixedly connected to the surface of the protective plate 513. The number of bumps 514 is evenly distributed on the surface of the protective plate 513. The bottom plate 4 will transmit the force to the bumps 514. At this time, the bumps 514 can increase the friction between the bottom plate 4 and the protective pad to prevent the bottom plate 4 from slipping off the protective pad. A connecting rope 515 is fixedly connected to the surface of the screw rod 502. The other end of the connecting rope 515 is fixedly connected to the square plate 507. The screw rod 502 will drive one end of the connecting rope 515 to move. At this time, the connecting rope 515 can prevent the screw rod 502 from falling when it is removed.

[0033] The overall working principle is as follows. When the die carrier is being installed, the two limit rods 501 on the bottom plate 4 can first be engaged with the card slots 503 on the buffer plate 504, and then the screw rod 502 is rotated. Using the thread of the screw rod 502 itself, the limit rod 501 is engaged with the card slot 503. At this time, one end of the connecting rope 515 will be driven to move by the screw rod 502. At this time, the connecting rope 515 can prevent the screw rod 502 from falling when it is removed. Then, the base 3, the lower die carrier 2, and the upper die carrier 1 are installed on the bottom plate 4. Then, the turning handle 512 is rotated. At this time, the turning handle 512 will drive the lead screw 509 to move along the surface of the fixing plate 508. At the same time, the lead screw 509 will move in the direction close to the base 3 by means of its own thread. At this time, the turning handle 512 can facilitate the rotation of the lead screw 509. Then, the abutting block 510 will be driven by the lead screw 509 to abut against the base 3. At the same time, one end of the telescopic rod 511 will be driven to move by the abutting block 510. At this time, the telescopic rod 511 can prevent the abutting block 510 from rotating as the lead screw 509 rotates. The fixing plate 508, the lead screw 509, and the abutting block 510 can be used to limit the base 3 to prevent misalignment when installing the lower die carrier 2 and the upper die carrier 1. When the upper die carrier 1 and the lower die carrier 2 are stressed, the forces received by the upper die carrier 1 and the lower die carrier 2 will be transmitted to the base 3, and then from the base 3 to the bottom plate 4. At this time, the bottom plate 4 will transmit the force to the convex block 514. At this time, the convex block 514 can increase the friction between the bottom plate 4 and the protective pad to prevent the bottom plate 4 from slipping off the protective pad. Then, the convex block 514 will transmit the received force to the protective plate 513. At this time, the protective plate 513 made of rubber can protect the bottom plate 4. Then, the protective plate 513 will transmit the received force to the buffer plate 504. At the same time, the buffer plate 504 will transmit the received force to the spring 506 and the damping rod 505. At this time, the spring 506 itself will generate a resilient force that cancels out the force received by the buffer plate 504 on the square plate 507. By setting the shock absorption device 5, through the mutual cooperation between the limit rod 501, the screw rod 502, the card slot 503, the buffer plate 504, the damping rod 505, the spring 506, and the square plate 507, the force received by the lower die carrier 2 can be slowed down, avoiding excessive pressure on the base 3 and the bottom plate 4 when the lower die carrier 2 is instantaneously stressed, which may cause the base 3 and the bottom plate 4 to shift, resulting in misalignment when installing the die carrier, slowing down the pressure received by the base 3 and the bottom plate 4, playing a certain protective role for the base 3 and the bottom plate 4, and improving the installation efficiency of the upper die carrier 1 and the lower die carrier 2.

[0034] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
