Description

Technical Field

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

[0002] In the traditional production process of fiber-reinforced polyurethane composite materials, the position of the core in the mold cavity is often inaccurate, the core-adjusting mechanism is too short, making core adjustment difficult, and the core is prone to deviation when drilling into the mold. Existing preformed mold frames involve a lot of welding, resulting in poor robustness and environmental impact. Adjustment requires adjusting the threading plate, which needs to be fixed at its four corners with eight bolts, making the adjustment process cumbersome and time-consuming.

[0003] For example, this utility model, authorized by announcement number CN217073443 U, discloses a copper tube yarn guiding preforming device, including a cold mold, a preforming mold frame, a forming mold, and a mold core. The forming mold includes a lower left module, a lower middle module, a lower right module, an upper left module, an upper middle module, and an upper right module. The lower left module, lower middle module, and lower right module are connected and fixed together by screws to form a lower mold. The upper left module, upper middle module, and upper right module are connected and fixed together by screws to form an upper mold. The upper mold and lower mold are fixed together by screws, and a cavity with the same shape as the cold mold is formed between the upper mold and the lower mold. Steel plates are arranged around the outer perimeter of the forming mold, and the steel plates are fixed together by screws to form a steel plate frame. This utility model has a reasonable structural design. The mold core is adjusted as a whole by the yarn feeding plate, so that its position in the cavity of the forming mold is accurate. The mold core is easy to adjust, and excess glue is filtered out, reducing the amount of glue entering the preforming mold frame. The yarn control is accurate, and the forming effect is good. However, the yarn threading plate of the copper tube yarn guide preforming device is fixed by screws at the four corners. When it is necessary to replace the yarn threading plate or adjust the distance, it wastes time and reduces work efficiency. Utility Model Content

The fixing bracket is located inside the I-beam mold frame, and the end of the fixing bracket is connected to a fixing plate located outside the I-beam mold frame via long bolts.

[0014] Furthermore, each of the fixed plates is connected to the end of the fixed frame by a long bolt at both ends, and the long bolt is located on one side of the long rod of the I-beam frame.

[0015] Furthermore, the length of the fixing plate is greater than the width of the long rod of the I-beam mold frame, and the distance between the two long bolts on the fixing plate is greater than the width of the long rod of the I-beam mold frame.

[0016] Compared with the prior art, the beneficial effects of the technical solution provided by this utility model are as follows: by movably installing the second and third threading plates on the I-beam mold frame, not only can the threading plates be replaced, but the distance between the first, second and third threading plates can also be adjusted, and the lateral position of the threading plates can also be adjusted, making the use more flexible.

[0024] 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.

[0025] See Figure 1-6A preformed mold frame for decorative panels used in construction projects includes two symmetrically arranged I-beam mold frames 4 and a horizontally placed straight mold frame 5 fixed between the two I-beam mold frames 4. From left to right, a first threading plate 1, a second threading plate 2, and a third threading plate 3 are arranged between the two I-beam mold frames 4 in the direction of yarn feeding. The first threading plate 1 is fixedly connected to the end of the I-beam mold frame 4. The second threading plate 2 and the third threading plate 3 are movably installed on the I-beam mold frame 4. A mold core mounting seat 24 is fixedly connected to the I-beam mold frame 4 between the first threading plate 1 and the second threading plate 2. A mold mounting seat 25 is fixed to the right end of the two I-beam mold frames 4.

[0026] Specifically, a straight mold frame 5 is welded to the upper and lower ends of the middle position of the opposite face of the I-beam mold frame 4, making the overall pre-forming mold frame more stable during operation. The first yarn-threading plate 1 and the four corners of the left end face of the I-beam mold frame 4 are provided with corresponding bolt holes. The first yarn-threading plate 1 is detachably connected to the left end face of the I-beam mold frame 4 by bolts, which makes it convenient to remove the first yarn-threading plate 1 for replacement and cleaning. The second yarn-threading plate 2 and the third yarn-threading plate 3 are movably installed on the I-beam mold frame 4, which makes it convenient for workers to replace the yarn-threading plates or adjust the distance, saving time.

[0027] The mold core mounting base 24 is an inverted U-shaped frame, including two vertical plates on the upper surface of the two I-beam mold frames 4 and a flat plate fixed between the two vertical plates. The end of the mold handle 231 is provided with multiple fixing holes 232. Bolts pass through the fixing holes 232 on the mold handle 231 and are detachably mounted on the flat plate. One end of the mold handle 231 is inserted into one end of the mold core 23 and fixed by bolts from the side.

[0028] The mold mounting base 25 includes two clamping plates connected to the inner side of the I-beam mold frame 4 by long bolts 22. The two ends of the clamping plates are connected to the support plate by long bolts 22. A forming mold 12 is provided at the opening between the clamping plates and the support plate. The clamping plates and the forming mold 12 are fixed together by long bolts 22.

[0029] like Figure 3 As shown, the first threading plate 1 is provided with two elongated first felt holes 181 and two second felt holes 182. The two second felt holes 182 are located between the two first felt holes 181. A plurality of U-shaped third felt holes 183 are symmetrically arranged between the two second felt holes 182. A C-shaped fourth felt hole 184 is provided on the right side of the third felt hole 183. The first threading plate 1 is provided with multiple sets of threading hole groups. The threading hole groups on the first threading plate 1 include a plurality of fine threading holes 19 arranged between the first felt holes 181 and the second felt holes 182 and on one side of the third felt holes 183.

[0030] Specifically, such as Figure 3As shown, there are six third felt holes 183. Three of these third felt holes 183 are arranged side-by-side at the lower part of the first threading plate 1, and these three third felt holes 183 are U-shaped. The other three third felt holes 183 are symmetrically arranged at the upper part of the first threading plate 1, opposite to the three lower third felt holes 183. The two second felt holes 182 are of the same length and shorter than the length of the first felt holes 181. The two second felt holes 182 are located close to the third felt holes 183, and the two first felt holes 181 are located outside the two second felt holes 182. The fine threading holes 19 between the first felt holes 181 and the second felt holes 182 are arranged in a matrix. Multiple fine threading holes 19 are irregularly arranged between the upper third felt holes 183, and multiple fine threading holes 19 are also irregularly arranged on the left and right sides of the area where the third felt holes 183 are located. Two fine yarn-threading holes 19 are provided on the upper side of the second felt hole 182 on the lower side; the first felt hole 181 and the second felt hole 182 are used to pass through wide polyester felt, and the third felt hole 183 and the fourth felt hole 184 are used to pass through narrow polyester felt. A glass fiber yarn is threaded through each fine yarn-threading hole 19. The polyester felt and glass fiber yarn passing through the first felt hole 181, the second felt hole 182, the third felt hole 183, the fourth felt hole 184 and the fine yarn-threading holes 19 on the first yarn-threading plate 1 are initially shaped and arranged according to the structure of the produced decorative panel. For example, it is ensured that the outer surface of the final produced decorative panel and the inner surface of the cavity are formed by the polyester felt through a heating and stretching process, so that the formed decorative panel has a long service life, a clean appearance and is easy to clean. The glass fiber yarn, as the main body of the decorative panel, can effectively ensure the mechanical strength of the decorative panel.

[0031] like Figure 4 As shown, the second threading plate 2 has a plurality of first core holes 185 arranged side by side. The upper and lower sides of the first core holes 185 are respectively provided with first felt holes 181 and second felt holes 182, which are both elongated strips. The right side of the first core holes 185 is provided with a fourth felt hole 184 in the shape of a C. The first threading plate 1 has a plurality of sets of threading hole groups. The threading hole groups on the second threading plate 2 include a plurality of fine threading holes 19 arranged between the first felt holes 181 and the second felt holes 182 and on one side of the first core holes 185, and coarse threading holes 191 on one side of the first core holes 185.

[0032] Specifically, such as Figure 4As shown, the second threading plate 2 has three first mold core holes 185, which are arranged side by side in the middle of the second threading plate 2, corresponding to the area where the six third felt holes 183 on the first threading plate 1 are located. The felt passing through the symmetrically arranged third felt holes 183 on the first threading plate 1 enters the corresponding first mold core holes 185. The lengths of the two second felt holes 182 are the same and less than the lengths of the first felt holes 181. The lower second felt hole 182 has an upward curved arc at its left end. The distance between the two second felt holes 182 on the second threading plate 2 is smaller than the distance between the two second felt holes 182 on the first threading plate 1. The two first felt holes 181 are respectively located outside the two second felt holes 182, and the distance between the two first felt holes is smaller than the distance on the first threading plate 1. Their left ends are both curved towards the middle. The arrangement of the fine threading holes 19 on the second threading plate 2 is the same as that on the first threading plate. Similar to 1, the distance between the fine threading holes 19 is reduced; multiple fine threading holes 19 are also irregularly arranged on the left and right sides of the third felt hole 183 area, and their distance is reduced relative to the distance on the first threading plate 1. The fine threading holes 19 in the area above the third felt hole 183 on the first threading plate 1 become coarse threading holes 191 on the second threading plate 2. The curvature of the second threading plate 2 is smaller than that of the fourth felt hole 184 on the first threading plate 1; wherein the first felt hole 181 and the second felt hole 182 is used to pass through wide polyester felt, 184 is used to pass through narrow polyester felt, 19 and 191 are respectively used to pass through one and several glass fiber yarns, and 185 is used to insert and fix the mold handle 231. The polyester felt and glass fiber yarns are gathered through the first felt hole 181, the second felt hole 182, the fourth felt hole 184, the fine felt hole 19 and the coarse felt hole 191 on the first yarn plate 1 to prepare for the next process.

[0033] like Figure 5 As shown, the third threading plate 3 is provided with a plurality of second mold core holes 186 on a flat surface. The upper and lower sides of the second mold core holes 186 are provided with first felt holes 181 and second felt holes 182, which are both elongated strips.

[0034] like Figure 5 As shown, the yarn threading hole group on the third yarn threading plate 3 includes a fine yarn threading hole 19 and a coarse yarn threading hole 191 disposed on one side of the second mold core hole 186.

[0035] like Figure 5As shown, there are three second core holes 186. The positions of the three second core holes 186 on the second threading plate 2 remain unchanged, but the second core holes 186 become elongated. The distance between the two first felt holes 181 on the second threading plate 2 is shortened, and the curvature at the left end is increased. The length of the two second felt holes 182 on the second threading plate 2 remains unchanged, but the width is increased, and the distance between them is shortened. The fine threading holes 19 and coarse threading holes 191 between the first core holes 185 on the second threading plate 2 remain unchanged, and the threading hole group composed of several fine threading holes 19 at both ends becomes an irregularly shaped coarse threading hole 191. Among them, the first felt holes 181 and the second felt holes 182 are used to pass through wide polyester felt, and the fourth felt hole 184 is used for... A narrow polyester felt is threaded through the material, and one and several glass fiber yarns are threaded through the fine threading holes 19 and coarse threading holes 191, respectively. Several glass fibers are gathered at the fine threading holes 19 at both ends of the second threading plate 2 and emerge from the coarse threading holes 191 on the third threading plate 3. The fine threading holes 19 between the first felt hole 181 and the second felt hole 182 of the second threading plate 2 are gathered together with the second felt hole 182 and emerge from the second felt hole 182 on the third threading plate 3. From the first threading plate 1 to the third threading plate 3, the distance between the felt holes and the threading holes gradually decreases and bends towards the shape of the decorative panel. The yarn control is accurate and the forming effect is good. The yarn will not be uneven in the profile because the felt holes and the threading holes on the threading plate are too scattered.

[0036] like Figure 1 and Figure 2 As shown, the second threading plate 2 and the third threading plate 3 are both movably mounted on the I-beam mold frame 4 via a fixing frame 20. The fixing frame 20 is located inside the I-beam mold frame 4, and the end of the fixing frame 20 is connected to a fixing plate 21 located outside the I-beam mold frame 4 via a long bolt 22.

[0037] Each of the fixed plates 21 is connected to the end of the fixed frame 20 by a long bolt 22 at both ends, and the long bolt 22 is located on one side of the long rod of the I-beam frame 4.

[0038] Specifically, the second yarn-threading plate 2 and the third yarn-threading plate 3 are welded with fixing frames 20 (i.e., the fixing frame 20 is a long rod) at their upper and lower ends facing the forming mold 12. The distance between the two fixing frames 20 is smaller than the distance between the two crossbars on the I-beam mold frame 4, so as to ensure that the second yarn-threading plate 2 and the third yarn-threading plate 3 have a certain vertical movement space to adjust the position of the second yarn-threading plate 2 and the third yarn-threading plate 3 relative to the mold core hole of the forming mold. The fixing plate 21 is set on the outside of the I-beam mold frame 4 (i.e., the upper and lower sides of the I-beam mold frame 4). The two ends of the fixing plate 21 and the fixing frame 20 are connected by long bolts 22. If the height of the yarn-threading plate is adjusted upward, it is only necessary to tighten the long bolts 22 on the upper fixing plate 21 and loosen the long bolts 22 on the lower fixing plate 21. The downward adjustment is the opposite. It can be understood that the long bolts 49 are in smooth contact with the second fixing plate 48 and are threadedly connected to the third fixing frame 47.

[0039] The length of the fixing plate 21 is greater than the width of the long rod of the I-beam mold frame 4, and the distance between the two long bolts 22 on the fixing plate 21 is greater than the width of the long rod of the I-beam mold frame 4; when the yarn threading plate is adjusted left and right, it is only necessary to loosen the long bolts 22 at the four corners of the yarn threading plate.

[0040] The working process of the pre-forming mold frame for decorative panels used in construction projects provided by this utility model is as follows:

[0041] First, fine-tune the distance, height, and left and right positions between the second threading plate 2 and the third threading plate 3. Simply loosen all the long bolts 22 at the four corners, adjust the height slightly, and then push the threading plates left and right to make the first threading plate 1, the second threading plate 2, the third threading plate 3, and the mold hole in the forming mold 12 at the same horizontal line. The glass fiber and polyester felt are punched in from the threading hole and felt hole on the first threading plate 1 at the left end of the preforming mold frame, and then pass through the second threading plate 2 and the third threading plate 3 in sequence into the forming mold 12.

[0042] 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.
