If the threaded adjustment method is directly adopted, the positioning mechanism will directly contact the object while also contacting the thread on the screw rod. The reaction force of the object positioning mechanism will be directly transmitted to the thread. Long-term use will easily damage the structure of the thread, and there is a risk of stripping or slipping. Utility Model Content

[0005] The utility model aims to solve the problem that the maximum adjustment range of the traditional direct-push adjustment structure in the prior art is limited by its own length, and proposes an adjustable mold frame.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustable mold frame, including a mold frame base, a positioning plate is slidably installed on the top of the mold frame base, a support plate is fixedly installed on the bottom of the positioning plate, the bottom of the support plate is overlapped on the outer wall of the mold frame base, the bottom of the support plate is fixedly connected to a connecting rod, an adjustment plate is slidably connected to the outer wall of the connecting rod, a guide groove is provided at the junction of the adjustment plate and the connecting rod, and one end of the adjustment plate is threadedly connected to a threaded rod.

[0007] Preferably, a receiving cavity is provided inside the mold frame base, the adjustment plate is located inside the receiving cavity, and the width of the adjustment plate is smaller than the width of the receiving cavity.

[0008] Preferably, a support block is fixedly mounted on the upper surface of the mold frame base.

[0009] Preferably, a through hole is provided inside the support block.

[0010] Preferably, an anti-dropout block is fixedly mounted on the upper surface of the support plate, and the anti-dropout block is slidably connected to the inside of the through hole.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides an adjustable mold frame, including a mold frame base 1, a positioning plate 2 is slidably installed on the top of the mold frame base 1, a supporting plate 5 is fixedly installed on the bottom of the positioning plate 2, the bottom of the supporting plate 5 is overlapped on the outer wall of the mold frame base 1, a connecting rod 6 is fixedly connected to the bottom of the support plate 5, an adjusting plate 3 is slidably connected to the outer wall of the connecting rod 6, a guiding groove 7 is provided at the junction of the adjusting plate 3 and the connecting rod 6, one end of the adjusting plate 3 is threadedly connected to a threaded rod 4, the threaded rod 4 is rotatably installed on one side of the mold frame base 1, the connecting rod 6 passes through the mold frame base 1, and a positioning opening 11 is provided at the junction of the mold frame base 1 and the connecting rod 6.

[0026] The specific settings and functions of this embodiment are described in detail below. The positioning plate 2 is installed on the top of the mold frame base 1, and the adjustment plate 3 is installed inside the mold frame base 1. The positioning plate 2 is mainly used to fix the mold. The support plate 5 at the bottom is slidably connected with the adjustment plate 3 through the connecting rod 6. When in use, the threaded rod 4 is rotated to drive the adjustment plate 3. During the movement of the adjustment plate 3, the guide chute 7 will push the support plate 5 through the connecting rod 6 to achieve the purpose of changing the position of the positioning plate 2;

[0027] The adjustment plate 3 is located inside the mold frame base 1 and will not occupy the space on the surface of the mold frame base 1. The guide groove 7 is in an inclined state. According to the Pythagorean theorem, the guide groove 7 will amplify the smaller displacement of the adjustment plate 3 and transfer it to the connecting rod 6, causing the connecting rod 6 to produce a larger displacement in the longitudinal direction, thereby eliminating the need to set up a longer adjustment mechanism. The existence of the adjustment plate 3 also prevents the positioning plate 2 from directly contacting the threads on the threaded rod 4, thereby protecting the threads.

[0028] Embodiment 2

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a receiving cavity 10 is provided inside the mold base 1, the adjustment plate 3 is located inside the receiving cavity 10, and the width of the adjustment plate 3 is smaller than the width of the receiving cavity 10, a support block 13 is fixedly installed on the upper surface of the mold base 1, a through hole 12 is provided inside the support block 13, an anti-slip block 8 is fixedly installed on the upper surface of the support plate 5, the anti-slip block 8 is slidably connected inside the through hole 12, a limit plate 9 is fixedly installed on the outer wall of the threaded rod 4, and the limit plate 9 is located on one side of the mold base 1.

[0030] The effect achieved by the entire embodiment is that the adjustment plate 3 is arranged in the accommodating cavity 10 and will not be affected by external factors. The width of the adjustment plate 3 is smaller than the width of the accommodating cavity 10, which leaves enough space for the adjustment plate 3 to move.

[0031] The support block 13 is used to limit the moving route of the positioning plate 2. The through hole 12 inside the support block 13 is directly slidably connected to the anti-dropping block 8 on the support plate 5, which can limit the position of the support plate 5 and improve the stability of the positioning plate 2 during movement;

[0032] The threaded rod 4 is rotatably mounted on one end of the limiting plate 9 , independently outside the mold frame base 1 , which can reduce the difficulty of operation, and the limiting plate 9 can ensure the stability of the threaded rod 4 .

[0033] The use method and working principle of the device: the positioning plate 2 is used to fix the mold. When in use, the mold is placed between the two positioning plates 2, and then the threaded rod 4 is rotated to drive the adjustment plate 3. During the movement of the adjustment plate 3, the guide chute 7 will push the support plate 5 through the connecting rod 6, and the support plate 5 will then drive the positioning plate 2 to move toward the center of the mold frame base 1 to complete the fixation of the mold;

[0034] The adjustment plate 3 is located inside the mold frame base 1 and will not occupy the space on the surface of the mold frame base 1. The guide groove 7 is in an inclined state. According to the Pythagorean theorem, the guide groove 7 will amplify the smaller displacement of the adjustment plate 3 and move the connecting rod 6 a greater distance, thereby eliminating the need to set up a longer adjustment mechanism. The presence of the adjustment plate 3 also prevents the positioning plate 2 from directly contacting the threads on the threaded rod 4.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
