[0030] See also Figure 1-3 The utility model provides a technical solution: a mold fixing seat for preventing parts from shifting, comprising:

[0031] The base 1 has a fixing groove 11 in the center, and a first slide groove 12 and a second slide groove 13 in the side that are connected to the fixing groove 11, and a mold is placed in the fixing groove 11;

[0032] The two opposite positioning mechanisms 2 include a first positioning plate 21 abutting against the outside of the mold and two second positioning plates 22 slidably connected to the inside of the first positioning plate 21. The ends of the first positioning plate 21 are slidably connected to the first slide groove 12 and the second slide groove 13 respectively. The first positioning plate 21 is provided with a first fixing bolt 23 on one side of the second slide groove 13.

[0033] The first pre-tightening mechanism 3 is arranged between the outer side of the first positioning plate 21 and the side wall of the fixing groove 11, and is used for elastic pre-tightening to adjust the distance between the first positioning plates 21 of the two positioning mechanisms 2;

[0034] The second pre-tightening mechanism is connected between the outer side of the second positioning plate 22 and the first positioning plate 21 to perform elastic pre-tightening and spacing adjustment for the two second positioning plates 22 sliding on the first positioning plate 21. The first positioning plate 21 is provided with a second fixing bolt 24 for fixing to the second positioning plate 22.

[0035] A cushion layer is provided on the bottom surface of the fixing groove 11 to provide vibration buffering for the bottom surface of the mold and the contact surface of the mold fixing seat, thereby reducing the impact of external vibration on the mold and avoiding the deviation of internal structural parts and stamping parts when the mold is used.

[0036] The first positioning plate 21 is provided with a corresponding slider 211 on one side of the first slide groove 12, and a third slide groove 212 is provided on the inner side of the first positioning plate 21. The third slide groove 212 is an L-shaped slide groove. An extension block is provided on the side of the second positioning plate 22. The extension block is slidably connected in the third slide groove 212. The extension block and the top of the first positioning plate 21 are both provided with internal threaded holes threadedly connected with the second fixing bolt 24. This facilitates the stable and interference-free sliding of the second fixing bolt 24 and the extension block in the L-shaped third slide groove 212, making the use of the mold fixing seat and the mold fixing operation more convenient.

[0037] The first pre-tightening mechanism 3 includes two first hinged columns 31 fixed to the side walls of the fixing groove 11, a second hinged column 33 fixed to the outside of the first positioning plate 21, and a telescopic rod 32 hinged between the first hinged column 31 and the second hinged column 33. In this embodiment, the connection of the telescopic rod 32 to the second hinged column 33 can be achieved by arranging the ends of the two telescopic rods 32 up and down and sleeve-hinged in sequence, or by sleeve-hinging one telescopic rod 32 on the upper and lower end surfaces of the other telescopic rod 32, and then sleeve-hinging together.

[0038] A first elastic member 34 is also provided between the second hinged column 33 and the fixing groove 11. Positioning side plates 14 are provided on both sides of the first elastic member 34 of the fixing groove 11. The top surface of the positioning side plates 14 is located below the first pre-tightening mechanism 3, so as to facilitate adaptive abutment positioning between the mold fixing seat and one side of molds of different sizes.

[0039] The second pre-tightening mechanism includes a base plate 213 vertically fixed on the inner side of the first positioning plate 21 and the outer side of the second positioning plate 22 and a second elastic member 214 connecting the base plate 213 and the outer side of the second positioning plate 22, so as to facilitate adaptive abutment positioning between the mold fixing seat and the other side of molds of different sizes.

[0040] The working principle of a mold fixing seat for preventing parts from shifting in this embodiment includes: the mold fixing seat is used to accurately position molds of different sizes, and an elastic buffer structure is set at the connection between the mold and the fixing seat to reduce the influence of external vibration on the mold, and avoid the shift of internal structural parts and stamping parts when the mold is used. When in use, first loosen the first fixing bolt 23, release the fixed state of the first positioning plate 21, push the first positioning plate 21 outward to the outermost side along the fixing groove 11 and the two side slide grooves, loosen the second fixing bolt 24, and push the second positioning plate 22 outward to the outermost side along the third slide groove 212, and re-tighten the fixing bolt. At this time, the first elastic member 34 and the second elastic member 214 are in a compressed state. Put the mold into the fixing groove 11, loosen the fixing bolts, so that the elastic member's rebound force drives the two first positioning plates 21 and the corresponding second positioning plate 22 to slide toward each other and tighten, and the telescopic rod 32 stretches and opens, and abuts against the side of the mold, and stabilizes by itself, so that the mold is in the center of the fixing groove 11, and then tighten the fixing bolts again to fix the mold, start using the mold, and process the workpiece. The overall operation of the mold fixing seat is simple, and the mold positioning is accurate. Through the first elastic member 31, the second elastic member 214, and the buffer layer on the bottom of the fixing groove, the vibration force at the connection between the fixing seat and the mold can be unloaded when there is external vibration, avoiding the problem of displacement of internal structural parts and stamping parts when the mold is used.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
