[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Embodiment 1:

[0023] like Figure 1As shown, the utility model provides a combined box-shaped angle material forming mold, including: a lower mold 5; an upper mold, the upper mold includes module I1, module II2, module III3 and module IV4. When the mold is closed, the module I1 and module III3 are installed at the ends of the two short sides of the lower mold 5, the module II2 and module IV4 are installed on the two long sides of the lower mold 5, and the module II2 and module IV4 are located between the module I1 and module III3. After the mold is closed, the module II2 and module IV4 are fitted with the module I1 and module III3.

[0024] The upper mold is divided into four different modules that are separately arranged. When the mold is closed, the upper mold can be detachably installed on the lower mold 5. After the mold is formed, it is convenient to remove the module I1, module II2, module III3 and module IV4. The four modules are removed one by one instead of removing the upper mold as a whole in the prior art, which can better ensure the integrity of the product.

[0025] A cavity 10 is formed between module Ⅰ1, module Ⅱ2, module Ⅲ3 and module Ⅳ4. The four sides of the cavity 10 are surrounded by the inner side surfaces of modules Ⅰ1, module Ⅱ2, module Ⅲ3 and module Ⅳ4 corresponding to each other. The bottom surface of the cavity 10 is the top surface of the lower mold 5, and the top of the cavity 10 is open, which is convenient for laying the product; bolts 6 and locating pins 7 are provided on the top of modules Ⅰ1, module Ⅱ2, module Ⅲ3 and module Ⅳ4. In this embodiment, two bolts 6 are provided, which are distributed on both sides of modules Ⅰ1, module Ⅱ2, module Ⅲ3 and module Ⅳ4. Two locating pins 7 are provided in this embodiment, which are distributed on the inner side of the bolts 6. The lower mold 5 is the positioning reference of the upper mold. Modules Ⅰ1, module Ⅱ2, module Ⅲ3 and module Ⅳ4 are fixedly installed on the lower mold 5 by bolts 6 and locating pins 7. The alignment of the product engraving lines indicates that there is no problem in the installation of the upper mold. The connection by means of bolts 6 and locating pins 7 ensures the accuracy of the connection. Bolts 6 and locating pins 7 are provided on the four modules, which are convenient for removing the four modules separately, thereby ensuring the accuracy of the product.

[0026] The tops of modules Ⅰ1, Ⅱ2, Ⅲ3 and Ⅳ4 are all provided with demoulding holes 9, which are provided to facilitate the removal of the four upper molds of modules Ⅰ1, Ⅱ2, Ⅲ3 and Ⅳ4.

[0027] The upper die and the lower die 5 are both made of 45# steel metal material by CNC machining, and the bolts 6 and the positioning pins 7 are standard parts that can be purchased from the market. Both sides of the lower die 5 are provided with lifting rings 8 for easy handling and lifting.

[0028] After the upper mold is installed, it is paved. The cut prepreg sheets are laid in order according to the engraved lines on the mold. After paving, it is packaged. The pasted products are placed in the order of demoulding cloth, isolation film, breathable felt, and vacuum bag. The vacuum bag is adhered to the mold with sealing tape and vacuumed with a vacuum nozzle to achieve the packaging effect; then it is sent to the autoclave for curing. The resin is cured by heating and vacuum pressure to form a product; after it is taken out of the tank at 60°C, the auxiliary materials are removed, and the upper mold is removed in the reverse order of installation to complete the demoulding of the product. The upper mold is installed on the lower mold 5 with bolts 6 and locating pins 7. When dismantling, just remove the bolts 6 and locating pins 7. The demoulding hole 9 is used to facilitate the removal of the upper mold. After removing the four separately set upper molds one by one, it is easy to demould the product and ensure the integrity of the product.

[0029] Embodiment 2:

[0030] like Figure 2 and Figure 3 As shown, the difference between this embodiment and the first embodiment is that a positioning bolt 11 is provided between module II2 and modules I1 and modules III3, and a positioning bolt 11 is provided between module IV4 and modules I1 and modules III3.

[0031] The positioning bolt 11 is in a U-shaped structure.

[0032] Modules Ⅰ1, Ⅱ2, Ⅲ3 and Ⅳ4 are installed on the top of the lower mold 5 by screws and positioning pins 7. Bolts 6 and positioning pins 7 only play a fixing role in the vertical direction. There is a lack of horizontal restraint between modules Ⅰ1, Ⅱ2, Ⅲ3 and Ⅳ4, which is easy to cause displacement. Positioning bolts 11 are nailed in between modules Ⅰ1 and Ⅱ2, modules Ⅱ2 and modules Ⅲ3, modules Ⅲ3 and modules Ⅳ4, and modules Ⅳ4 and modules Ⅰ1, which can ensure the stability between the upper molds, avoid displacement between the upper molds, and further improve the accuracy of product molding. The positioning bolts 11 are set in a U-shaped structure, which is easy to remove when removing the upper mold, and the operation is convenient.

[0033] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
