[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1 An adjustable paint mold fork shown includes a mold fork with a mounting plate 2 and two fork rods 3. There are multiple mold forks, and the multiple mold forks are all installed on the mold base 1. It also includes an adjustment unit for adjusting the distance between the two fork rods 3 to adapt to paint positioning molds of different specifications.

[0023] An adjustment unit is provided, through which the opening distance between the two fork rods 13 on the same mounting plate 2 can be adjusted so as to adapt to the clamping of paint positioning molds of different specifications.

[0024] As a preferred implementation in this embodiment, Figure 1-3 As shown, the adjustment unit includes a T-shaped block 4 arranged at the end of the fork rod 3 and a rotating shaft 7 rotatably arranged on the mounting plate 2 through a U-shaped plate 6. The T-shaped block 4 is slidably arranged in a T-shaped slot 9 arranged at the front end of the corresponding mounting plate 2. A gear rod 5 is installed at the upper end of the two fork rods 3 correspondingly arranged on the same mounting plate 2, and the two gear rods 5 are arranged in parallel. A driving gear 8 is installed on the rotating shaft 7, and the driving gear 8 is respectively gear-connected with the two gear rods 5. A driving member 10 is installed on the upper end of the rotating shaft 7, and the operator can pinch or hold the driving member 10 to drive the rotating shaft 7 to rotate.

[0025] When making adjustments, the shaft 7 can be rotated and the driving gear 8 on the shaft 7 can be used to drive the two gear rods 5 to move relative to or away from each other, thereby adjusting the distance between the two fork rods 3, thereby achieving the installation of paint positioning molds of different coarse and fine specifications. The setting of the T-shaped block 4 can ensure that the two fork rods 3 can move in a stable straight line.

[0026] It should be noted that: 1. The two fork rods 3 are both arranged vertically on the mounting plate 2; 2. The driving member 10 can be arranged as a round block; 3. An elastic damping sleeve is arranged at the connection between the U-shaped plate 6 and the rotating shaft 7, which can have a certain hindering effect on the rotation of the rotating shaft 7, which is conducive to ensuring the stability of the two fork rods 3 after adjustment.

[0027] As a preferred implementation in this embodiment, reinforcing plates 11 are fixed to the upper and lower ends of the fork rod 3 close to the mounting plate 2 , and the opposite end surfaces of the two reinforcing plates 11 are in sliding contact with the upper and lower end surfaces of the mounting plate 2 respectively.

[0028] Since the weight of the paint positioning mold is borne by the two fork rods 3 and is sometimes subjected to longitudinal pulling force, the reinforcing plate 11 is provided to strengthen the longitudinal structural strength of the fork rods 3 to prevent them from being bent.

[0029] As a preferred implementation in this embodiment, a synchronous adjustment mechanism is also included for simultaneously adjusting the distance between two fork rods 3 on a plurality of mold forks.

[0030] The spacing of multiple fork rods 3 on the mold base 1 can be adjusted at the same time, saving adjustment time and ensuring the consistency of the opening spacing between two fork rods 3 on multiple mounting plates 2.

[0031] As a preferred implementation in this embodiment, the synchronous adjustment mechanism includes a worm 12 rotatably arranged on the mold base 1 through two fixed plates 13, the driving member 10 is configured as a worm gear, and the worm 12 is meshingly connected with a plurality of worm gears.

[0032] During use, the worm 12 can be rotated manually, and the worm 12 drives multiple worm wheels to rotate simultaneously, thereby adjusting the distance between two fork rods 3 on multiple mounting plates 2 at the same time.

[0033] It should be noted that, first, an elastic damping ring is provided on the left fixed plate 13 and at the point where the worm 12 penetrates. The inner wall of the elastic resistance ring partially wraps the outer part of the worm 12, so that there is a certain resistance to the rotation of the worm 12. This resistance of the push rod can prevent the worm from rotating and causing the distance between the two fork rods 3 to change; second, the cooperation of the worm gear 12, since the worm gear 12 has a self-locking function, can effectively prevent the worm 12 from rotating after the fork rod 3 is subjected to force through the cooperation of the toothed rod 5 and the driving gear 8, so that the opening distance between the two fork rods 3 remains stable after adjustment.

[0034] As a preferred implementation scheme in this embodiment, a scale ring 14 is fixed on the left fixed plate 13, the axis of the scale ring 14 is on the same straight line as the axis of the worm 12, the worm 12 passes through the inner hole of the scale ring 14, and a triangular indicator head 15 is provided on the outer surface of the worm 12.

[0035] When the worm 12 is rotated, the tip of the triangular indicator head 15 arranged thereon can be rotated in coordination with the angle scale on the scale ring 14. When positioning the paint molds of different specifications, the triangular indicator head 15 can be rotated to the corresponding angle scale line to facilitate the spacing adjustment.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
