[0022] 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.

[0023] Please see Figure 1-5 A lower mold assembly with a fine-tuning mechanism includes a mounting base 1, a straight plate 2 at the bottom of the mounting base 1, a worktable 3 above the mounting base 1, a through hole 17 at the top of the worktable 3, a connecting shell 5 fixedly mounted at the bottom of the worktable 3, a connecting screw 13 on the outer wall of the straight plate 2, a connecting nut 12 threadedly connected to the outer wall of the connecting screw 13, an adjusting screw 4 sleeved on the inner wall of the through hole 17, a sealing plate 16 fixedly sleeved on the outer wall of the adjusting screw 4, and an adjusting screw 16 fixedly mounted at the bottom of the adjusting screw 4. The bottom of the adjusting screw 15 and the sealing plate 16 abuts against the return spring 14. The bottom end of the adjusting screw 15 is provided with a circular plate 8. The bottom of the worktable 3 is fixedly equipped with a straight rod 10. The outer wall of the straight rod 10 is fixedly equipped with a limit plate 11. The bottom end of the straight rod 10 is provided with a circular plate 9. The top of the mounting base 1 is respectively provided with a through hole 18, a movable hole 19 and a movable groove 21. The inner wall of the movable hole 19 is provided with a limit groove 20. The top of the mounting base 1 is fixedly equipped with a sleeve 7. The inner wall of the sleeve 7 is slidably connected to a lifting cylinder 6.

[0024] In the above structure, the mounting base 1, straight plate 2, worktable 3, adjusting screw 1 4, connecting shell 5, lifting cylinder 6, sleeve 7, circular plate 1 8, return spring 14, adjusting screw 2 15, and sealing plate 16 are arranged so that during use, the user can rotate the adjusting screw 1 4 to move the sealing plate 16 and lifting cylinder 6 downward, thereby adjusting the distance between the mounting base 1 and the worktable 3. This facilitates the user in adjusting the height of the lower mold, thereby improving the production accuracy and practicality of the lower mold assembly.

[0025] In a preferred embodiment, the inner wall of the through hole 18 is threadedly connected to the outer wall of the adjusting screw 15, the bottom of the adjusting screw 15 is provided with a blind hole, the inner wall of the blind hole is threadedly connected with a screw, and the circular plate 8 is fixedly connected to the adjusting screw 15 by the screw.

[0026] In the above structure, through the arrangement of the circular plate 8 and the adjusting screw 15, when the user rotates the adjusting screw 4, the adjusting screw 15 will also rotate, thereby causing the sealing plate 16 to compress the reset spring 14, causing both the worktable 3 and the lifting cylinder 6 to descend. This achieves the effect of adjusting the distance between the mounting base 1 and the worktable 3, thus ensuring that the operation of the lower mold assembly is not affected.

[0027] In a preferred embodiment, the outer walls of the straight rod 10 and the limiting plate 11 are slidably connected to the straight rod 10 and the limiting plate 11, respectively, and both the straight rod 10 and the limiting plate 11 are made of galvanized iron.

[0028] In the above structure, galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the wear of both during operation, thereby extending their service life. In addition, galvanized iron also has the characteristics of low cost, which reduces the production and maintenance costs of the lower mold assembly.

[0029] In a preferred embodiment, both the outer walls of the straight plate 2 and the connecting shell 5 are provided with round holes, and the inner wall of the round holes is fitted with the outer wall of the connecting screw 13.

[0030] In the above structure, through the provided round hole and connecting screw 13, the user can fix the workbench 3 and the straight plate 2 by rotating the connecting nut 12, which facilitates the user's assembly of the lower mold assembly, thereby facilitating the user's disassembly and assembly of the lower mold assembly, improving the user's disassembly and assembly efficiency, and also improving the practicality of the lower mold assembly.

[0031] In a preferred embodiment, the bottom of the sealing plate 16 is rotatably connected to the top of the lifting cylinder 6, and the bottom of the sealing plate 16 abuts against the top of the return spring 14.

[0032] In the above structure, the lifting cylinder 6 and sealing plate 16 are designed so that when the user rotates the adjusting screw 4 during use, the sealing plate 16 will move downward, thereby pressing down on the lifting cylinder 6 and causing the lifting cylinder 6 to move downward. This achieves the effect of adjusting the distance between the mounting base 1 and the worktable 3. The cooperation between the lifting cylinder 6 and the sleeve 7 also prevents the lifting cylinder 6 from tilting or even shifting position during the lifting process, thus improving the stability of the lower mold assembly during operation.

[0033] In a preferred embodiment, the outer wall of the connecting nut 12 fits against the outer wall of the connecting shell 5, and the connecting shell 5 is fixedly connected to the straight plate 2 through the connecting nut 12.

[0034] In the above structure, the connecting shell 5 and connecting nut 12 are provided. By tightening the connecting nut 12, the straight plate 2 and the connecting shell 5 can be fixedly connected, thereby ensuring that the straight plate 2 and the connecting shell 5 will not separate after connection. It can also ensure the lower mold supports the material and prevent the worktable 3 from sinking during the bending process, thus further improving the stability of the lower mold assembly during operation.

[0035] In a preferred embodiment, the outer wall of the adjusting screw 4 is rotatably connected to the inner wall of the through hole 17, and there are two adjusting screws 4, both of which are symmetrically distributed along the top of the worktable 3.

[0036] In the above structure, the two adjusting screws 4 allow the user to easily adjust the height of the worktable 3 during operation by rotating the two adjusting screws 4, thereby ensuring that the worktable 3 remains stable during adjustment and thus ensuring the normal use of the lower mold assembly.

[0037] In a preferred embodiment, there are two movable grooves 21, and the inner wall of the movable groove 21 is slidably connected to the outer wall of the straight plate 2.

[0038] In the above structure, through the set movable groove 21 structure, when the user rotates the adjustment screw 4, the straight plate 2 will rise and fall along the inner wall of the movable groove 21, thereby ensuring that the worktable 3 will not loosen or even tilt during the lifting process, thus improving the stability of the worktable 3 during the lifting process.

[0039] Working principle: First, during operation, the user can insert the straight plate 2 into the connecting shell 5, and then insert the connecting screw 13 into the round hole. This allows the user to rotate the connecting nut 12 to make it fit against the outer wall of the connecting shell 5, thus facilitating the user's disassembly and assembly of the lower mold assembly and improving the efficiency of disassembly and assembly. During operation, the sealing plate 16 is rotated by rotating the adjusting screw 4. At this time, the adjusting screw 15 will rise and fall along the inner wall of the through hole 17, thereby driving the worktable 3 to rise and fall. The straight plate 2 will rise and fall along the inner wall of the movable groove 21, thereby adjusting the distance between the mounting base 1 and the worktable 3. This makes it easier for the user to adjust the distance between the upper and lower molds, thereby improving the accuracy of the mold assembly in the production process and the practicality of the lower mold assembly.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
