Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a molding die for decorative panels used in construction projects. Background Technology

[0002] A molding die, also known as a mold, is a tool made to scale the shape and structure of a material, using pressing or casting to shape it into a specific form. In the production of decorative panels, plastic in a viscous state is passed through a die with a specific cross-sectional shape under high temperature and pressure, and then cooled and solidified at a lower temperature to produce continuous profiles with the desired cross-sectional shape. Conventional mold structures require simultaneous heating as the material passes through the mold core during production, resulting in a complex core structure and numerous mold components. This leads to potential issues with mold structural stability, necessitating improved technologies to address these problems.

[0003] This utility model, authorized by announcement number CN217622311U, discloses a pultrusion mold for fiberglass special-shaped tubes, including a forming mold frame, a mold, and a mold adjustment frame. The mold includes a lower mold, a middle mold, and a top module. The lower mold is composed of a lower middle module, a lower left module, and a lower right module, which are fixed together by module fastening screws I. The middle mold is composed of middle module I and middle module II, which are located between the lower mold and the top module and are symmetrically arranged. The top module, the middle mold, and the lower mold are fixed together by module fastening screws II. The mold adjustment frame is fixed to the forming mold frame by fastening screws II and is composed of an upper plate, a side plate, and a lower plate, which are fixed together by fastening screws I. The mold of this utility model consists of three parts: a lower mold, a middle mold, and a top module, which are connected by bolts and are relatively fixed firmly, meeting the pultrusion requirements for special-shaped tubes and facilitating the adjustment of the mold position. However, the mold core and the holes for inserting the mold core in the pultrusion mold of this FRP (fiberglass reinforced plastic) tube are not suitable for producing decorative panels.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Example 1

[0022] See Figure 1-3 A molding die for decorative panels used in construction projects includes a die body 1 formed by combining an upper die and a lower die. The die body 1 has a core hole along its length. Three plate-shaped cores 2 are inserted side by side in the core hole. A die handle 9 is fixed to one end of the core 2 extending out of the core hole on the yarn feeding side. Multiple pairs of electromagnetic coil heating plates 3 are provided on the upper and lower surfaces of the die body 1. A plug 7 is provided on one side of each electromagnetic coil heating plate 3. A thermocouple 8 is provided between each pair of electromagnetic coil heating plates 3 and inserted into the die body 1 for accurate temperature measurement.

[0023] In this embodiment, the upper and lower molds are connected and fixed with bolts to ensure that there are no gaps when they are joined together, preventing raw materials from leaking out. The mold core 2 is inserted into the middle of the mold core hole. The gap between the inner wall of the mold core hole and the mold core 2 forms the shape of the decorative panel. Before the mold core 2 is inserted, the surface smoothness is ensured. The surface of the mold core 2 can be treated with chrome plating and polishing to ensure that the decorative panel is burr-free. The upper and lower symmetrical surfaces of the mold body 1 are provided with electromagnetic coil heating plates 3 to melt and shape the inorganic fibers and polyester felt that enter the mold core hole. The electromagnetic coil heating plates 3 can accurately control the temperature to ensure that the raw materials melt in the mold body 1 and are fixedly shaped when exiting the mold body 1.

[0024] In this embodiment, the upper and lower surfaces of the mold body 1 are provided with slots, which can hold the electromagnetic coil heating plate 3.

[0025] In this embodiment, both the upper and lower surfaces of the upper and lower molds are provided with slots. The size of the slots is the same as that of the electromagnetic coil heating plate 3, and the electromagnetic coil heating plate 3 can be directly inserted into the slots.

[0026] In this embodiment, the electromagnetic coil heating plate 3 is fixed to the mold body 1 by bolts; corresponding bolt holes are opened at the four corners of the electromagnetic coil heating plate 3 and on the mold body 1, and it is directly fixed to the mold body 1 by bolts.

[0027] like Figure 3As shown, the end of the mold handle 9 away from the mold core 2 is provided with a plurality of fixing holes 10. By setting the fixing holes 10, the mold handle 9 is fixed to the mold frame with bolts.

[0028] like Figure 3 As shown, there are 3 mold cores 2, which are arranged side by side at intervals in the mold core holes.

[0029] like Figure 3 As shown, the upper sidewall of the mold core hole has multiple grooves along its length. The upper surface of the produced decorative board is required to have multiple anti-slip grooves. The grooves and the anti-slip grooves have the same opening. By setting the anti-slip grooves, pedestrians are prevented from slipping when walking.

[0030] Example 2

[0031] This embodiment is another implementation based on Embodiment 1. The difference between this embodiment and Embodiment 1 lies in the fixing method of the electromagnetic coil heating plate 3. Specifically, as follows... Figure 1 and Figure 2 As shown, each pair of electromagnetic coil heating plates 3 is clamped and fixed on the mold body 1 by the same fixing device. The fixing device includes a U-shaped fixing frame 4 and a threaded rod 5. The lower end of the U-shaped fixing frame 4 is supported on the lower side of the electromagnetic coil heating plate 3. The upper end of the U-shaped fixing frame 4 is threadedly connected to the threaded rod 5. The lower end of the threaded rod 5 abuts against the upper electromagnetic coil heating plate 3.

[0032] In this embodiment, when installing the U-shaped fixing frame 4, the U-shaped fixing frame 4 is inserted from left to right into one end of the mold body 1. The lower end of the U-shaped fixing frame 4 is aligned with the middle position of the electromagnetic coil heating plate 3 to ensure the overall stability. The upper side of the U-shaped fixing frame 4 is fixedly connected to a fixing plate. The upper surface of the fixing plate is provided with a through threaded hole. The threaded rod 5 is threaded into the threaded hole. When fixing the electromagnetic coil heating plate 3, the outer surface of the electromagnetic coil heating plate 3 is brought into contact with the inner surface of the U-shaped fixing frame 4, and the threaded rod 5 is rotated to contact the electromagnetic coil heating plate 3 for fixing.

[0033] like Figure 2 As shown, a support block 6 is fixed to the lower end of the threaded rod 5.

[0034] Specifically, a frustum-shaped support block 6 is fixedly connected to the lower end of the threaded rod 5. The contact area between the support block 6 and the electromagnetic coil heating plate 3 is larger than the contact area at the bottom of the threaded rod 5. When the electromagnetic coil heating plate 3 needs to be clamped, it prevents the electromagnetic coil heating plate 3 from being crushed. The support block 6 is made of a high-temperature resistant soft material.

[0035] The working process of the molding die for decorative panels used in construction projects provided by this utility model is as follows:

[0036] First, place the upper electromagnetic coil heating plate 3 according to the actual production situation. Then, fix the electromagnetic coil heating plate 3 to the mold body 1 with bolts, or insert it into the U-shaped fixing frame 4 from left to right. Rotate the threaded rod 5 to make the lower support block 6 reach the highest point. Then, insert the lower electromagnetic coil heating plate 3 into the middle position of the lower end of the U-shaped fixing frame 4. Rotate the threaded rod 5 to make the support block 6 contact the upper electromagnetic coil heating plate 3 for fixing.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
