Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a multifunctional mold fixture for machining. Background Technology

[0002] In the machining process, fixtures are needed to hold the mold to prevent it from shaking during processing. Currently, fixtures mainly use clamping plates to hold the mold from the outer wall, but their stability needs to be improved. At the same time, current fixtures only have a single clamping function, and their functionality also needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to provide a multifunctional mold fixture for machining, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional mold fixture for machining, comprising: a clamping table and a mold disposed on the clamping table, further comprising: multiple equidistant sliding openings on the outer wall of the top of the clamping table, multiple clamping plates slidably connected to the inner wall of the sliding openings, and a bending plate installed at the bottom of the clamping table, a bidirectional threaded rod rotatably mounted on the bending plate, and a motor installed at the bottom of the bending plate, the output shaft of the motor being connected to the bidirectional threaded rod, and a traction component and a lifting component being screwed to the upper and lower ends of the bidirectional threaded rod respectively, a heat dissipation component being installed on the top of the lifting component, and a heat dissipation opening being opened in the middle of the outer wall of the bottom of the clamping table.

[0005] The traction assembly includes a first screw block and a plurality of equidistant traction rods rotatably mounted on the outer wall of the first screw block.

[0006] The lifting assembly includes a second screw block, connecting plates mounted on the outer walls of both sides of the second screw block, and connecting rods fixed to the two connecting plates.

[0007] The heat dissipation assembly includes an annular box, an inlet pipe connected to one end of the inner wall at the bottom of the annular box, and an outlet pipe connected to the inner wall on one side of the annular box.

[0008] The top of the traction rod is rotatably connected to the bottom of the corresponding clamping plate.

[0009] Both ends of the bottom outer wall of the bent plate have through holes, and the two connecting rods are inserted through the two through holes respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model discloses a multifunctional mold clamping fixture for machining. The mold can be placed on the clamping table for processing. Before processing, the motor drives the bidirectional threaded rod to rotate, causing the four clamping plates to move closer together and abut against the four corners of the mold, thus clamping the mold from the four corners, making the mold more stable. At the same time, the heat dissipation component is driven to rise and stick to the outer wall of the bottom of the mold to dissipate heat from the bottom of the mold, preventing the temperature of the bottom of the mold from rising and causing thermal expansion of the mold material, which would lead to changes in the mold size. This ensures the accuracy of mold processing. Compared with traditional clamping fixtures, it is more stable and has better functionality. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides a multifunctional mold fixture for machining, including: a clamping table 1 and a mold 2 disposed on the clamping table 1, and further including: multiple sliding openings 3 equidistantly distributed on the top outer wall of the clamping table 1, multiple clamping plates 4 slidably connected to the inner wall of the sliding openings 3, and a bending plate 5 installed at the bottom of the clamping table 1, a bidirectional threaded rod 6 rotatably installed on the bending plate 5, and a motor 7 installed at the bottom of the bending plate 5, the output shaft of the motor 7 being connected to the bidirectional threaded rod 6, and a traction component 8 and a lifting component 9 respectively screwed to the upper and lower ends of the bidirectional threaded rod 6, a heat dissipation component 10 installed on the top of the lifting component 9, and a heat dissipation opening 11 in the middle of the bottom outer wall of the clamping table 1.

[0020] It should be noted that: the mold 2 can be placed on the clamping table 1 for processing. Before processing, the motor 7 can drive the bidirectional threaded rod 6 to rotate, causing the traction component 8 to descend while the lifting component 9 rises. The traction component 8 descends and simultaneously drives the four clamping plates 4 to move closer together, respectively pressing against the four corners of the mold 2, thus clamping the mold 2 from the four corners, making the mold 2 more stable. At the same time, the rising lifting component 9 drives the heat dissipation component 10 to rise and stick to the bottom outer wall of the mold 2. During the processing of the mold 2, the heat dissipation component 10 can be used to dissipate heat from the bottom of the mold 2, preventing the temperature of the bottom of the mold 2 from rising and causing thermal expansion of the mold 2 material, which would lead to changes in the size of the mold 2, thus ensuring the processing accuracy of the mold 2. After the mold 2 is processed, the motor 7 can drive the bidirectional threaded rod 6 to rotate in the opposite direction, causing the traction component 8 to rise and simultaneously push the four clamping plates 4 away from each other, releasing the clamping of the mold 2. At the same time, the rising component 9 descends and drives the heat dissipation component 10 to descend, making it easier to observe the bottom of the mold 2. Compared with traditional clamping, this method is more stable and has better functionality.

[0021] In a preferred embodiment, the traction assembly 8 includes a first screw block 801 and a plurality of equidistant traction rods 802 rotatably mounted on the outer wall of the first screw block 801.

[0022] It should be noted that the rotation of the bidirectional threaded rod 6 can drive the first threaded block 801 to move up or down, which in turn pushes the clamping plates 4 away from or closer to each other through the traction rod 802.

[0023] In a preferred embodiment, the lifting assembly 9 includes a second screw block 901, connecting plates 902 mounted on the outer walls of both sides of the second screw block 901, and connecting rods 903 fixed on the two connecting plates 902.

[0024] It should be noted here that when the bidirectional threaded rod 6 rotates, it causes the first threaded block 801 to descend, which in turn causes the second threaded block 901 to rise.

[0025] In a preferred embodiment, the heat dissipation assembly 10 includes an annular box 1001, an inlet pipe 1002 connected to one end of the bottom inner wall of the annular box 1001, and an outlet pipe 1003 connected to one side inner wall of the annular box 1001.

[0026] It should be noted that: the rise of the second screw block 901 can drive the two connecting rods 903 and the annular box 1001 to rise, so that the annular box 1001 is attached to the bottom of the mold 2. Water can be poured into the annular box 1001 through the water inlet pipe 1002, and the water is discharged through the water outlet pipe 1003, thereby achieving heat dissipation at the bottom of the mold 2.

[0027] Working principle: The mold 2 can be placed on the clamping table 1 for processing. Before processing, the motor 7 drives the bidirectional threaded rod 6 to rotate, causing the first threaded block 801 to descend and the second threaded block 901 to rise. The descent of the first threaded block 801, through the four traction rods 802, simultaneously causes the four clamping plates 4 to move closer together, respectively pressing against the four corners of the mold 2, thus clamping the mold 2 from the four corners and making the mold 2 more stable. At the same time, the rise of the second threaded block 901 can drive the two connecting rods 903 and the annular box 1001 to rise, so that the annular box 1001 is attached to the bottom of the mold 2. Water can be supplied to the annular box through the inlet pipe 1002. Water is poured into 1001 and then discharged through the outlet pipe 1003 to dissipate heat from the bottom of mold 2, preventing the temperature of the bottom of mold 2 from rising and causing thermal expansion of the mold 2 material, which would lead to changes in the size of mold 2 and ensure the processing accuracy of mold 2. After processing of mold 2, the motor 7 can drive the bidirectional threaded rod 6 to rotate in the opposite direction, causing the first screw block 801 to rise and push the four clamping plates 4 away from each other, releasing the clamping of mold 2. At the same time, the second screw block 901 descends, causing the annular box 1001 to descend, making it easier to observe the bottom of mold 2. Compared with traditional clamps, it is more stable and has better functionality.
