Description

Technical Field

[0001] The utility model relates to the technical field of door and window components, in particular to a mold for producing prefabricated door and window components. Background Art

[0002] Currently, in the production of prefabricated components for doors and windows, due to the different sizes of doors and windows, each production cycle requires first determining mold specifications based on production requirements before assembling the mold. During the alternating stages of prefabricated door and window production, workers must first disassemble the mold and then re-define the mold's length and width based on the actual dimensions. This approach is time-consuming to disassemble and can lead to workers violently smashing or throwing the mold, increasing mold wear. Furthermore, changes in mold size require calculation, which is very cumbersome. Therefore, a mold for the production of prefabricated door and window components was proposed. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a mold for producing prefabricated door and window components.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The first frame is in the middle, and the second frame and the third frame are on both sides of the first frame, wherein:

[0008] The adjacent bottom corners of the first frame, the second frame and the third frame are respectively provided with connecting legs, and the two connecting legs are rotatably connected via a fixed shaft;

[0009] Connecting arms are rotatably installed on both sides of the adjacent top corners of the first frame, the second frame and the third frame. The movable ends of the four connecting arms adjacent to the first frame and the second frame and the first frame and the third frame are rotatably installed on two connecting columns. The center of the connecting column is spirally inserted into the threaded rod, and the bottom end of the threaded rod is rotatably fixed on the mounting column. The end of the mounting column away from the threaded rod is connected to the fixed shaft, and the top of the threaded rod is provided with a rotating handle.

[0010] In a preferred technical solution, the second frame and the third frame each have a positioning hole on their respective right-angled sides opposite to the hypotenuse for screwing in the locking screws.

[0011] In a preferred technical solution, connecting shafts are respectively provided at both ends of the connecting column, and the movable ends of the four connecting arms on both sides of the connecting column are arranged in pairs and are rotatably fixed to the two ends of the connecting column through the connecting shafts.

[0012] In a preferred technical solution, the long sides of the first frame, the second frame and the third frame are external sides for measuring the sizes of doors and windows.

[0014] The beneficial effects of the utility model are:

[0015] The prefabricated component mold proposed in this solution solves the problem that the mold samples used in the production of prefabricated door and window components are not very universal and have limited usability. The original integral mold is split into several identical mold units, and the mold units are assembled in a detachable form. Workers can increase or decrease the number of mold units according to the size requirements of doors and windows to meet the molding standards specified for prefabricated components. In addition, since each mold unit is relatively independent and detachable, it also provides convenience for removing the mold after the subsequent prefabricated component production is completed, and has high versatility and practicality.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In this embodiment, refer to Figure 1-3 A mold for producing prefabricated components for doors and windows is finally formed by a plurality of identical mold units 1 fixedly connected end to end by locking screws 2.

[0022] For a single mold unit 1, the mold unit 1 includes a first frame 3, a second frame 4 and a third frame 5. Figure 1 Or attach Figure 2 It can be seen that the first frame 3 is an isosceles trapezoidal structure, the second frame 4 and the third frame 5 are both right-angled trapezoidal structures, and the second frame 4 and the third frame 5 form a trapezoid consistent with the structure of the first frame 3 after assembly.

[0023] The first frame 3 is in the middle, and the second frame 4 and the third frame 5 are on both sides of the first frame 3, wherein:

[0024] As attached Figure 2 As shown, adjacent bottom corners of the first frame 3 , the second frame 4 and the third frame 5 are respectively provided with connecting legs 12 , and the two connecting legs 12 are rotatably connected via a fixed shaft 6 .

[0025] As attached Figure 3 As shown, connecting arms 7 are rotatably mounted on both sides of the adjacent top corners of the first frame 3, the second frame 4 and the third frame 5. Here, the movable ends of the four connecting arms 7 adjacent to the first frame 3 and the second frame 4 and the first frame 3 and the third frame 5 are rotatably mounted on two connecting columns 8. Figure 3 It can be seen that connecting shafts 13 are respectively provided at both ends of the connecting column 8 , and the movable ends of the four connecting arms 7 on both sides of the connecting column 8 are arranged in pairs and are rotatably fixed to the two ends of the connecting column 8 through the connecting shafts 13 .

[0026] It is important to note that the center of the connecting post 8 is screwed into the threaded rod 9. The bottom end of the threaded rod 9 is rotatably fixed to the mounting post 10 via a threaded sleeve. The end of the mounting post 10, away from the threaded rod 9, is connected to the fixed shaft 6. The top of the threaded rod 9 is provided with a rotary handle 11. When the threaded rod 9 rotates, the threaded rod 9 is engaged, and the connecting post 8 can move back and forth along the length of the rod 9, thereby controlling the rotation of the connecting arms 7 on both sides about their respective fulcrums.

[0027] For assembling multiple mold units 1, the second frame 4 and the third frame 5 each have a positioning hole on the right-angled side opposite the hypotenuse for screwing in the locking screw 2. By tightening the locking screw 2, multiple mold units 1 can be assembled together in sequence to form a complete structure.

[0028] The long sides of the first frame 3 , the second frame 4 and the third frame 5 are external sides, which are used to measure the sizes of doors and windows.

[0029] Since the sizes of door prefabricated components or window prefabricated components are different, it is necessary to change the length of the external edge according to different length sizes. In actual application, workers can assemble several mold units 1 together according to the size and length.

[0030] Since doors and windows have right angles, Figure 1 As can be seen, after several mold units 1 are assembled, workers can rotate the threaded rod 9 on the mold unit 1 at a right angle to the planned door or window, causing a bend between the first frame 3 and the third frame 5 (here, the first frame 3 and the second frame 4 can also be bent as needed). When the bending angle reaches 90°, the mold unit 1 can be turned. Because the bending of the first frame 3, the second frame 4, and the third frame 5 is achieved by rotating the threaded rod 9, and the threads have a self-locking function, they can ensure that they remain vertical only in the required positions, while remaining flat in other positions.

[0031] Finally, it is necessary to add that Figure 2 As shown, the angle α formed by the long side and the hypotenuse of the first frame 3 is acute, and this acute angle α is less than 45°. The purpose of this design is that when α is less than 45°, the bending angle of the mold unit 1 at a designated position can exceed 90°, thereby ultimately meeting the requirements of right-angled components for doors and windows.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
