[0037] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Example 1:
[0039] like Figures 1 to 3 As shown, this utility model provides a combined shovel-type thermoforming mold device, including an upper mold frame 1 and a lower mold frame 2 that are positioned vertically opposite each other. The lower mold frame 2 is fixed on a base, while the upper mold frame 1 is movable vertically. An upper combined mold 5 is installed on the lower side of the upper mold frame 1, and a lower combined mold 6 is installed on the upper side of the lower mold frame 2. A vertically arranged guide block 3 is fixed at each of the four corners of the upper mold frame 1, and the four guide blocks 3 are arranged in a rectangular pattern. A vertically arranged guide groove 4 is embedded at each of the four corners of the lower mold frame 2, with the guide blocks 3 and guide grooves 4 engaging vertically. When the upper mold frame 1 moves downwards to enter the pressing stage, the guide blocks 3 slide in the guide grooves 4 to guide the upper mold frame 1, ensuring the pressing quality.
[0040] Combined Figures 3 to 6 As shown, the upper assembly mold 5 consists of multiple upper split modules that are sequentially connected and independently fixed on the upper mold frame 1. These mainly include a left upper module 51, a middle standard upper module 52, a make-up size upper module 53, an adjustment upper module 54, and a right upper module 55. Multiple middle standard upper modules 52 and multiple adjustment upper modules 54 are provided. In actual use, the length of the entire upper assembly mold 5 can be adjusted by changing the number of adjustment upper modules 54 to accommodate bending plates of different lengths. The purpose of providing a make-up size upper module 53 is to minimize the number of other upper split modules and to adjust the make-up size upper module 53 to achieve the desired size.
[0041] Similar to the upper combined mold 5, the lower combined mold 6 is also composed of multiple lower split modules that are sequentially connected and independently fixed on the lower mold frame 2. These different lower split modules mainly include a left lower module 61, a middle standard lower module 62, a fitting-size lower module 63, an adjusting lower module 64, and a right lower module 65; among them, multiple middle standard lower modules 62 and adjusting lower modules 64 are provided. In actual use, the lower combined mold 6 is adaptively adjusted with the upper combined mold 5 to achieve the required length of the lower combined mold 6. The upper mold frame 1 drives the upper combined mold 5 downwards to press against the lower combined mold 6, causing the forming parts to deform and completing the pressing and forming operation.
[0042] Example 2:
[0043] Based on the above embodiment one, as follows Figures 1 to 6 As shown, the lower side of the upper mold base 1 has an elongated groove for positioning the upper combined mold 5. The left upper module 51, the middle standard upper module 52, the fitting size upper module 53, the adjustment upper module 54, and the right upper module 55 are sequentially fitted into the elongated groove of the upper mold base 1. Each upper split module has a countersunk hole, and a positioning bolt is installed in the countersunk hole. Each upper split module is fastened to the upper mold base 1 by the positioning bolt. In addition, each upper split module has a positioning groove on its edge. The positioning groove cooperates with the corresponding positioning platform on the upper mold base 1 to improve the stability of each upper split module.
[0044] Similarly, the upper side of the lower mold base 2 is surrounded by a corresponding elongated groove, and each lower sub-module in the lower combined mold 6 is embedded in the elongated groove of the lower mold base 2. Countersunk holes are provided on the left lower module 61, the middle standard lower module 62, the fitting size lower module 63, the adjustment lower module 64, and the right lower module 65. Positioning bolts are installed in the countersunk holes, and each lower sub-module is fastened to the lower mold base 2 by the positioning bolts.
[0045] Example 3:
[0046] Based on the above embodiment two, as follows Figures 1 to 3 As shown, and Figure 7 and Figure 8 As shown, multiple material support assemblies 7 are installed on the lower mold frame 2 to quickly eject the pressed parts from the mold after the pressing operation is completed. The material support assembly 7 is located below the lower combined mold 6 and is fixed to the lower mold frame 2. The material support assembly 7 has a liftable spring block 75, and a clearance hole 77 is provided on the left lower module 61 and part of the middle standard lower module 62. The upper end of the spring block 75 is slidably set in the corresponding clearance hole 77. After pressing is completed, the spring block 75 can push the pressed parts out of the lower combined mold 6.
[0047] The material support assembly 7 includes a guide sleeve 74 fixed to the lower side of the lower mold base 2, and a spring block 75 slidably mounted in the guide sleeve 74. A through hole is provided on the lower mold base 2 at the upper end of the guide sleeve 74, through which the spring block 75 passes into the clearance hole 77. A plug 71 is fixed to the lower end of the guide sleeve 74 by a fixing bolt 73 to prevent the spring block 75 from falling out of the guide sleeve 74. Two guide holes are provided at the lower end of the spring block 75, and guide posts 72 are installed in the guide holes, with their lower ends fixed to the plug 71. There is a gap between the guide posts 72 and the guide holes. A compression spring 76 is sleeved on the guide posts 72, with its two ends abutting against the plug 71 and the guide holes of the spring block 75, respectively. The compression spring 76 provides an upward thrust to the spring block 75.
[0048] After pressing is completed, the upper combined mold 5 separates from the lower combined mold 6 along with the upper mold frame 1. The compression spring 76 pushes the spring block 75 to move upward, so that the upper end of the spring block 75 extends out of the clearance hole 77, pushing the pressed part on the lower combined mold 6 to disengage, thereby realizing the automatic demolding of the pressed part.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
