Description

Technical Field

[0001] The utility model relates to the field of hot pressing dies, and more specifically, to a hot pressing die applied to pulp molded products. Background Art

[0002] Hot pressing (or hot pressing forming) of pulp molded products is a process of forming pulp or paper materials into products with specific shapes and strengths through hot pressing. This technology is widely used in the manufacture of various paper packaging, cardboard, environmentally friendly tableware, and other pulp molded products.

[0003] During the processing of pulp molded products, steam will disperse outside the equipment when the joints are engaged. After being exposed to high temperature and humidity conditions for a long time, the high-precision performance of local parts of the equipment may be affected. The steam is not easily blocked and processed in time, which will affect the use efficiency of the base of the workbench. Therefore, it is necessary to design a hot pressing die for pulp molded products with a steam recovery and treatment function to solve the above problems. Summary of the Utility Model

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] (1) In this solution, side arc-shaped hollow strips with steam shielding functions are arranged at the four corners on the upper side of the bottom cross plate. The steam generated at the connection between the upper template and the lower template is first blocked, and during the floating process of the steam, it first contacts the cooling liquid guide plate. The condensation force generated by the cold water inner tank inside the cooling liquid guide plate is used to deform the steam into liquid, and the liquid is guided into the flexible water pipe strip according to the side arc-shaped hollow strip, and finally collected through the water collecting middle frame. The collected liquid can be reused, avoiding the drawback that the high-precision performance of the local part of the equipment may be affected under the conditions of long-term exposure to high temperature and humidity.

[0018] (2) Moreover, during the cooperation between the upper template and the side arc-shaped hollow strip, rotating universal spheres can also be arranged at the connection positions between the side arc-shaped hollow strip and the upper template and the lower template. The universal spheres can make the displacement of the upper template smoother, and there is no risk of extrusion deformation of the side arc-shaped hollow strip, which is beneficial to ensuring the liquid collection efficiency of the cooperation between the side arc-shaped hollow strip and the upper template.

[0029] Please refer to Figures 1 - 4, a hot pressing die applied to pulp molded products, comprising an operating table base 1. Vertical rod shafts 6 are fixedly connected to the four corners of the upper end of the operating table base 1. A top cross plate 4, a middle cross plate 3 and a bottom cross plate 2 are successively installed from top to bottom at the outer ends of the plurality of vertical rod shafts 6. A upper template 7 is fixedly connected to the lower end of the middle cross plate 3. A lower template 10 is fixedly connected to the upper end of the bottom cross plate 2. Fixed vertical plates 12 are fixedly connected to the four corners of the upper end of the bottom cross plate 2. A side arc-shaped hollow strip 11 is fixedly connected to one end of the fixed vertical plate 12 close to the upper template 7. A cold water inner groove 16 is fixedly connected to the upper side of the inner end of the side arc-shaped hollow strip 11. A cooling liquid guide plate 17 is fixedly connected to the inner side wall of the cold water inner groove 16.

[0030] Please refer to Figures 1 - 4 , a number of pulp molded products are filled between the upper template 7 and the lower template 10. The lower template 10 and the upper template 7 are docked with each other. The side arc-shaped hollow strip 11 is located outside the upper template 7. A hydraulic driver 5 is arranged at the upper end of the top cross plate 4. The output end of the hydraulic driver 5 is connected to the middle cross plate 3. A flexible water pipe strip 14 is fixedly connected to the lower end of the side arc-shaped hollow strip 11. A water collecting middle frame 13 is fixedly connected to the inner end of the operating table base 1. The water collecting middle frame 13 is interconnected with the plurality of flexible water pipe strips 14. Universal spheres 15 are rotatably connected to the upper and lower sides of one end of the side arc-shaped hollow strip 11 away from the lower template 10. The universal spheres 15 are in contact with the outer side walls of the upper template 7 and the lower template 10.

[0031] Please refer to Figures 1 - 4In this solution, the pulp molded product is filled between the upper template 7 and the lower template 10, and a certain pressure and temperature are applied to solidify it into a finished product. During the processing of the pulp molded product, steam will be generated at the connection when it is engaged and will float outside the equipment. If it is exposed to high temperature and humidity for a long time, the local high-precision performance of the equipment may be affected. If the steam is not easily blocked in time, it will affect the use efficiency of the workbench base 1.

The condensation force generated by the inner groove 16 deforms the steam into water, and guides the water into the soft water pipe strip 14 according to the side arc hollow bar 11, and finally collects it through the water collecting frame 13. The collected water can be reused to avoid long-term exposure to high temperature and humidity conditions, which may affect the local high-precision performance of the equipment. In addition, when the upper template 7 cooperates with the side arc hollow bar 11, a rotating universal ball 15 can be set at the connection position between the side arc hollow bar 11 and the upper template 7 and the lower template 10. The universal ball 15 can make the displacement process of the upper template 7 smoother, and it is not easy to cause the risk of extrusion deformation of the side arc hollow bar 11, which is beneficial to ensure the efficiency of the liquid collection of the side arc hollow bar 11 and the upper template 7.

[0032] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
