Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a positioning mechanism as Figures 1-3 shown, which includes a downward pressing component 1 and an adjusting component 2. The downward pressing component 1 and the adjusting component 2 cooperate to complete the positioning work of the product lower mold;

[0023] The downward pressing component 1 includes a U-shaped cavity, which is composed of two circular holes and a rectangular connecting hole. The two circular holes are symmetrically opened at the top of the workbench of the hot melt press. The rectangular connecting hole is opened between the two circular holes. Two lifting columns 101 are arranged in the inner cavity of the U-shaped cavity. The two lifting columns 101 are respectively located in the inner cavities of the two circular holes. A limiting sliding hole is opened at the bottom of the lifting column 101. A limiting sliding rod 106 is slidably sleeved in the inner cavity of the limiting sliding hole. The limiting sliding rod 106 and the limiting sliding hole are used to ensure that the lifting column 101 can move smoothly. The bottom end of the limiting sliding rod 106 is fixedly connected to the bottom of the inner wall of the U-shaped cavity. A strip-shaped force-bearing block 102 is arranged between the two lifting columns 101. The cross-section of the strip-shaped force-bearing block 102 is a right triangle. The strip-shaped force-bearing block 102 is fixedly connected between the two lifting columns 101. T-shaped holes are opened at the tops of the two lifting columns 101. T-shaped rotating blocks 103 are arranged in the inner cavities of the two T-shaped holes. The two T-shaped rotating blocks 103 are rotatably connected to the inner cavities of the corresponding T-shaped holes. Pressing blocks 104 are arranged at the tops of the two T-shaped rotating blocks 103. The size of the pressing blocks 104 can be changed according to actual needs. The bottoms of the two pressing blocks 104 are fixedly connected to the tops of the corresponding T-shaped rotating blocks 103. A plurality of first reset springs 105 are equidistantly arranged at the bottom of the strip-shaped force-bearing block 102. The first reset springs 105 are used to drive the strip-shaped force-bearing block 102, the lifting column 101 and the pressing block 104 to automatically perform a reset movement, improving the convenience of operation. The number of the first reset springs 105 can be changed according to actual needs. The bottom ends of the plurality of first reset springs 105 are fixedly connected to the bottom of the inner wall of the U-shaped cavity. The top ends of the plurality of first reset springs 105 are fixedly connected to the bottom of the strip-shaped force-bearing block 102;

[0024] The adjusting assembly 2 includes a threaded hole and a telescopic hole. The threaded hole is formed in the front surface of the workbench of the hot melt press. The telescopic hole is formed between the threaded hole and the U-shaped cavity. The threaded hole communicates with the telescopic hole. The inner cavity of the threaded hole is provided with an adjusting bolt 201. The outer wall of the adjusting bolt 201 is threadedly connected to the inner wall of the threaded hole. The adjusting bolt 201 rotating clockwise in the threaded hole will move towards the telescopic hole, and the adjusting bolt 201 rotating counterclockwise in the threaded hole will move away from the telescopic hole. The inner cavity of the telescopic hole is provided with an adjusting rod 202. A strip-shaped sliding hole is formed in the outer wall of the adjusting rod 202. A limiting slider 203 is slidably sleeved in the inner cavity of the strip-shaped sliding hole. The limiting slider 203 and the strip-shaped sliding hole are used to ensure that the adjusting rod 202 can move smoothly. The limiting slider 203 is fixedly connected to the inner cavity of the telescopic hole. One side of the limiting slider 203 is fixedly connected with a second return spring 204. The second return spring 204 can undergo elastic deformation to drive the adjusting rod 202 to automatically perform a reset movement, improving the convenience of operation. One end of the second return spring 204 is fixedly connected to one side of the inner wall of the strip-shaped sliding hole. A notch groove is formed at one end of the adjusting rod 202. A movable roller 205 is arranged in the inner cavity of the notch groove. The movable roller 205 can not only improve the smoothness of the adjusting rod 202 driving the strip-shaped force-bearing block 102 to move, but also play a role in protecting the adjusting rod 202 and the strip-shaped force-bearing block 102.

[0025] As Figure 1 shown, this embodiment provides a hot melt press, and the hot melt press includes the above-mentioned positioning mechanism.

[0026] The working principle of the present utility model:

[0027] When it is necessary to position the lower mold on the workbench of the hot melt press, first rotate the two pressing blocks 104 to the upper sides of the two protruding sides of the lower mold. During this process, the two pressing blocks 104 need to be symmetrical so that the lower mold is uniformly stressed. After the positions of the two pressing blocks 104 are determined, rotate the adjusting bolt 201 clockwise. The adjusting bolt 201 rotating clockwise in the threaded hole will drive the adjusting rod 202 to move towards the strip-shaped force-bearing block 102. After the movable roller 205 at the end of the adjusting rod 202 contacts the inclined surface of the strip-shaped force-bearing block 102, as the adjusting rod 202 and the movable roller 205 continue to move, the strip-shaped force-bearing block 102 will move vertically downward. The vertically downward movement of the strip-shaped force-bearing block 102 will drive the two lifting columns 101 and the two pressing blocks 104 to move vertically downward and cooperate with the workbench of the hot melt press to complete the positioning work of the lower mold, realizing the positioning work of the lower mold in one step, simplifying the operation steps, and improving the convenience of the hot melt press for positioning the lower mold of the product.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
