Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 5As shown, a hot press mold for Tibetan-style decorative lines includes an upper mold 1 and a lower mold 2. The upper mold 1 is provided with multiple sliding sleeves, and the lower mold 2 is provided with multiple guide shafts. The multiple sliding sleeves slide in cooperation with the guide shafts. Both the upper mold 1 and the lower mold 2 are provided with heating channels. The heating channels include an inlet channel 11, an outlet channel 14, a branch channel 13, and a through channel 12. The three through channels 12 are arranged in parallel. The branch channels 13 have a V-shaped structure. The multiple branch channels 13 are spaced apart and are connected to the three through channels 12. The inlet channel 11 is connected to one end of two through channels 12 on both sides, and the outlet channel 14 is connected to the other end of two through channels 12 on both sides. Both the outlet channel 14 and the inlet channel 11 are connected to pipe joints 6. The ends of the inlet channel 11, the outlet channel 14, the branch channel 13, and the through channel 12 are all provided with plugs. In this embodiment, the hot press mold is used to produce Tibetan-style decorative lines. A cavity is formed between the upper mold 1 and the lower mold 2. Resin material is placed in the cavity, and the lower mold 2 is pressed down to heat the resin material so that it fills the cavity and is formed. During processing, the mold needs to be processed. Both the upper mold 1 and the lower mold 2 need to be heated. Post-heating channels are set in both the upper mold 1 and the lower mold 2. Heating oil of a certain temperature is introduced into the heating channels to heat the upper mold 1 and the lower mold 2. In this embodiment, the heating oil is introduced from the inlet channel 11, and then the heating oil flows from the inlet channel 11 into the two side channels 12. Then the heating oil flows from the channel 12 into the V-shaped branch channel 13 and into the middle channel 12. By setting multiple branch channels 13, the upper mold 1 and the lower mold 2 can be heated evenly. The V-shaped branch channel 13 can adapt to the V-shaped shape of the product, so the resin material can be heated evenly, improving the production quality of the product.

[0024] Furthermore, the upper mold 1 is fixed on the mounting plate 3. In this example, the upper mold 1 is fixed on the mounting plate 3, and the mounting plate 3 is fixed on the hydraulic press. The hydraulic press drives the mounting plate 3 to move up and down, so that the sliding sleeve and the guide shaft slide together, thus processing the product. The material of the sliding sleeve is copper, which can prevent the sliding sleeve and the guide shaft from getting stuck after the mold cools down.

[0025] Furthermore, the system also includes a base 4, on which two support seats 5 are provided. The lower mold 2 is fixed to the support seats 5. Multiple support columns 17 are provided on the base 4 between the two support seats 5, with the top of each support column 17 abutting against the bottom of the lower mold 2. In this example, the lower mold 2, support seats 5, and base 4 are fixed together with bolts, and the lower mold 2 is supported by the support seats 5. Since the bottom of the lower mold 2 is suspended between the two support seats 5, long-term use may cause deformation of the lower mold 2. By providing multiple support columns 17 on the base 4 to support the lower mold 2, deformation can be avoided.

[0026] Furthermore, the top surface of the lower mold 2 is provided with multiple grooves 9, and thickness limiting blocks 10 are provided in the grooves 9. In this example, the thickness limiting blocks 10 are fixed in the grooves 9 by bolts. The top surface of the thickness limiting blocks 10 is higher than the top surface of the lower mold 2. When the upper mold 1 is pressed down, the bottom surface of the upper mold 1 is in contact with the top surface of the thickness limiting blocks 10, so that a fixed gap is formed between the upper mold 1 and the lower mold 2. This allows the thickness of the product to be determined. By replacing the thickness limiting blocks 10 with different thicknesses, products of different thicknesses can be produced to meet different usage requirements. It is simple to use.

[0027] Furthermore, the lower mold 2 is provided with multiple lower positioning blocks 15, and the upper mold 1 is provided with multiple upper positioning blocks 21. Each lower positioning block 15 has a positioning groove, and each upper positioning block 21 has a positioning protrusion that engages with the positioning groove. In this embodiment, the lower positioning blocks 15 are fixed to the lower mold 2 with bolts. Lower positioning blocks 15 are provided on all four sides of the lower mold 2, and upper positioning blocks 21 are fixed to corresponding positions on the upper mold 1 with bolts. The positioning groove is located at the center of the top of the lower positioning block 15. When the lower mold 2 is pressed down, the positioning protrusion inserts into the positioning groove, thus positioning the upper mold 1 and the lower mold 2.

[0028] Furthermore, it also includes an ejection mechanism, which includes a cylinder 7, an ejector rod 18, a top plate 8, and a pressure plate 19. The pressure plate 19 is fixed on the top plate 8, and cylinders 7 are fixedly installed at both ends of the top plate 8. A bayonet 20 is provided on the base 4, and a slot is provided on the cylinder rod of the cylinder 7. The slot cooperates with the bayonet 20 to limit the movement. The bottom of the ejector rod 18 is a stepped shaft, and the pressure plate 19 is provided with multiple stepped holes. The stepped shaft at the bottom of the ejector rod 18 cooperates with the stepped holes of the pressure plate 19 to fix the ejector rod 18 on the pressure plate 19. The upper mold 1 is provided with a sliding hole that penetrates the upper mold 1, and the ejector rod 18 is slidably connected to the sliding hole. The upper mold 1 is provided with a guide hole, and the top plate 8 is provided with a light axis 16, which is slidably connected to the guide hole. In this embodiment, after the product is formed, it needs to be removed. To facilitate the separation of the product from the mold, an ejection mechanism is set up for demolding. The cylinder body of the cylinder 7 is fixed on the top plate 8. The cylinder rod is limited by the cooperation of the bayonet 20 and the slot. When the product needs to be ejected, the cylinder body of the working cylinder 7 drives the top plate 8 to rise. The optical shaft 16 set on the top plate 8 moves in the guide hole, thus guiding the product. The ejector rod 18 is driven by the top plate 8 to slide along the sliding hole to separate the product from the lower mold 2, making it easy to remove. A stepped shaft is set at the bottom of the ejector rod 18, which is limited between the top plate 8 and the pressure plate 19 to reduce fatigue damage at the root of the ejector rod 18 and extend its service life.

[0029] Furthermore, a limiting block 22 is provided on the top of the pressure plate 19. In this embodiment, when the cylinder 7 is working, the top of the limiting block 22 abuts against the bottom of the upper mold 1, thus limiting the extreme position of the rise of the push rod 18.

[0030] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
