[0004] To achieve the above objectives, this application adopts the following technical solution: a support frame for large-format molds, comprising:
[0005] The first support mechanism includes a first crossbeam extending in the left-right direction and a pair of first columns extending in the up-down direction, the tops of the pair of first columns being connected to the left and right ends of the first crossbeam respectively.
[0006] A second support mechanism is arranged behind the first support mechanism. The second support mechanism includes a second crossbeam extending in a left-right direction and a pair of second columns extending in a vertical direction. The tops of the pair of second columns are respectively connected to the left and right ends of the second crossbeam. Both the first and second crossbeams are H-shaped steel sections. The thickness of the first crossbeam in the vertical direction is greater than that of the second crossbeam in the vertical direction, and the length of the first crossbeam in the left-right direction is greater than that of the second crossbeam in the left-right direction.
[0007] An intermediate connecting mechanism is provided between the first support mechanism and the second support mechanism. The intermediate connecting mechanism includes a pair of horizontal braces extending in the front-rear direction and a pair of horizontal braces arranged opposite each other. Each of the horizontal braces is connected between the second crossbeam and the first crossbeam, and the pair of horizontal braces are arranged opposite each other. Each of the horizontal braces is connected between the second crossbeam and the first crossbeam, and each of the horizontal braces has an angle of 30°-70° with the first crossbeam.
[0008] The large-width mold is hoisted onto the first crossbeam.
[0009] In the above technical solution, a further preferred embodiment is that the first support mechanism further includes a pair of first reinforcing diagonal braces arranged opposite each other on the left and right sides. The pair of first reinforcing diagonal braces are located in the same plane as the first crossbeam and the pair of first columns. One end of each of the first reinforcing diagonal braces is connected to the first crossbeam, and the other end is connected to the corresponding first column.
[0010] In the above technical solution, a further preferred embodiment is that each of the first reinforcing diagonal braces is connected to the first crossbeam by a first reinforcing column, and the first reinforcing column is parallel to the first upright column.
[0011] In the above technical solution, it is further preferred that the rear ends of the pair of cross braces are respectively connected to the left and right ends of the second crossbeam.
[0012] In the above technical solution, a further preferred embodiment is that the intermediate connecting mechanism further includes a pair of vertical diagonal braces arranged opposite each other on the left and right sides.

Detailed Implementation
[0022] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.
[0023] This application provides a support frame for a large-format mold, capable of supporting the large-format mold and a metering pump system connected to the large-format mold. For example... Figure 1 As shown, the support frame 100 includes: a first support mechanism 10, a second support mechanism 20 located behind the first support mechanism 10, and an intermediate connecting mechanism 30 connecting the first support mechanism 10 and the second support mechanism 20.
[0024] like Figure 1-4 As shown, the first support mechanism 10 includes a first crossbeam 1 extending in the left-right direction and a pair of first columns 2 extending in the up-down direction. The tops of the pair of first columns 2 are respectively connected to the left and right ends of the first crossbeam 1, thereby forming a gantry structure.
[0025] The second support mechanism 20 is arranged behind the first support mechanism 10. The second support mechanism 20 includes a second crossbeam 3 extending in the left-right direction and a pair of second columns 4 extending in the up-down direction. The tops of the pair of second columns 4 are respectively connected to the left and right ends of the second crossbeam 3, forming a gantry structure. The first support mechanism 10 and the second support mechanism 20 form a double gantry to strengthen the support strength of the large-width mold 200 and the metering pump system 300.
[0026] like Figure 1 , 3 As shown in Figure 4, the intermediate connecting mechanism 30 includes a pair of horizontal braces 5 extending in the front-rear direction and a pair of horizontally opposed diagonal braces 6. Each horizontal brace 5 is connected between the second crossbeam 3 and the first crossbeam 1, and the pair of horizontal braces 5 are arranged horizontally opposite each other. Each horizontally opposed diagonal brace 6 is connected between the second crossbeam 3 and the first crossbeam 1, and each horizontally opposed diagonal brace 6 has an included angle α of 30°-70° with the first crossbeam 1. The pair of horizontal braces 5 is used to connect the first support mechanism 10 and the second support mechanism 20. The pair of horizontally opposed diagonal braces 6 form a triangular structure with the first crossbeam 1 and the second crossbeam 3 to strengthen and stabilize the connection between the first crossbeam 1 and the second crossbeam 3, and to prevent the first crossbeam 1 and the second crossbeam 3 from deforming under load. This allows the intermediate connecting mechanism 30 to support the metering pump system 300, and it also supports the first support mechanism 10 from the rear side of the first support mechanism 10 together with the second support mechanism 20.
[0027] The first support mechanism 10 is used to support the large-format mold 200, which is hoisted onto the first crossbeam 1. To enhance the stability of the support for the large-format mold 200, both the first crossbeam 1 and the second crossbeam 3 are made of H-shaped steel, and the thickness of the first crossbeam 1 in the vertical direction is greater than that of the second crossbeam 3 in the vertical direction. The cross-sectional area of the first column 2 is greater than that of the second column 4. The support strength of the first support mechanism 10 is greater than that of the second support mechanism 20. The single-beam design of the first support mechanism 10 and the second support mechanism 20 reduces the amount of steel used and reduces the footprint of the equipment.
[0028] like Figure 1 , 2As shown, the first support mechanism 10 also includes a pair of first reinforcing diagonal braces 7 arranged opposite each other. The pair of first reinforcing diagonal braces 7 are located in the same plane as the first crossbeam 1 and the pair of first columns 2. One end of each first reinforcing diagonal brace 7 is welded to the first crossbeam 1, and the other end is welded to the corresponding first column 2. After the welding of the first reinforcing diagonal braces 7 is completed, the first support mechanism 10 is annealed as a whole to ensure that the first crossbeam 1 does not deform. Each first reinforcing diagonal brace 7, the first crossbeam 1, and the corresponding first column 2 form a triangular structure, thereby strengthening the connection between the first crossbeam 1 and the first column 2. Each first reinforcing diagonal brace 7 is connected to the first crossbeam 1 by a first reinforcing column 8, which is parallel to the first column 2, further strengthening the connection strength of the first reinforcing diagonal braces 7.
[0029] like Figure 1-3 As shown in the embodiment of this application, the first crossbeam 1 matches the length of the wide mold 200 in the left and right directions. In order to reduce the floor space, the length of the second crossbeam 3 in the left and right directions is less than the length of the first crossbeam 1 in the left and right directions. The rear ends of a pair of cross braces 5 are respectively connected to the left and right ends of the second crossbeam 3.
[0030] like Figure 1 , 4 As shown, the intermediate connecting mechanism 30 also includes a pair of vertical diagonal braces 9 arranged opposite each other on the left and right. One end of each vertical diagonal brace 9 is connected to the horizontal brace 5 on the corresponding side, and the other end is connected to the second column 4 on the corresponding side. Each vertical diagonal brace 9, the horizontal brace 5 on the corresponding side, and the second column 4 are in the same plane. Each vertical diagonal brace 9, the corresponding horizontal brace 5, and the corresponding second column 4 form a stable triangular structure, which vertically supports the horizontal brace 5 to prevent it from sagging and strengthens the stability of the connection between the second support mechanism 20 and the intermediate connecting mechanism 30.
[0031] The second support mechanism 20 also includes a pair of second reinforcing diagonal braces 11 arranged opposite each other. The pair of second reinforcing diagonal braces 11 are located in the same plane as the second crossbeam 3 and the pair of second columns 4. One end of each second reinforcing diagonal brace 11 is welded to the second crossbeam 3, and the other end is welded to the corresponding second column 4. After the welding of the second reinforcing diagonal braces 11 is completed, the entire second support mechanism 20 is annealed to remove stress and ensure that the second crossbeam 3 does not deform. Each second reinforcing diagonal brace 11 forms a triangular structure with the second crossbeam 3 and the corresponding second column 4, which can strengthen the connection between the second crossbeam 3 and the second column 4 and enhance the overall stability of the second support mechanism 20.
[0032] The second support mechanism 20 also includes a pair of left-right opposing rear diagonal braces 13. Each second column 4 is connected to a rear diagonal brace 13. Each rear diagonal brace 13 has an included angle β of 30°-70° with the corresponding second column 4, and the bottom of each rear diagonal brace 13 is flush with the bottom of the corresponding second column 4. The rear diagonal braces 13 provide support for the second support mechanism 20 behind the second columns 4, enhancing the stability of the support frame 100.
