Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a mold convenient for connecting a carbon fiber product and a support rib. Background Art
[0002] The installation structure of exterior parts of an automobile, such as wheel arches and spoilers, is connected to a mating part 16 by means of a double-sided tape 15 (see Figure 1 ). Since the curved surfaces of the product and the mating part 16 are inconsistent, plastic support ribs 11 need to be added for support. As Figure 2 shown, the connection between a traditional carbon fiber component 3 and a plastic support rib 11 uses glue 12 as an intermediate. First, the carbon fiber component 3 is cured and formed, and the plastic support rib 11 is injection-molded. Then, the plastic support rib 11 is placed on a tooling 13, glue 12 is applied to the plastic support rib 11, and the plastic support rib 11 is pressed onto the carbon fiber component 3 by a pressing block 14, and heated and kept under pressure. This connection method requires different molds to manufacture the carbon fiber component and the support rib, with high costs and many processes. At the same time, using glue to bond the carbon fiber component and the support rib increases the cost of the bonding tooling and the labor cost, and increases the risk of product quality rejection. Summary of the Utility Model

[0012] Preferably, the bolt is a sector structure with a gradually increasing thickness from one radius to another radius.
[0013] With the above structural design, the thickness of the bolt gradually increases, and the bolt is pressed tightly in the clamping seat during the rotation process of the bolt. The connection method is simple, the operation is convenient, and the sealing is tight.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-7, the present utility model provides a technical solution: a mold for facilitating the connection between a carbon fiber product and a support rib, including a male mold 2 and a female mold 1 that cooperate with each other. A carbon fiber component 3 is placed in the forming cavity formed by the male mold 2 and the female mold 1 when they are closed. The carbon fiber component 3 is a carbon fiber prepreg processed from materials such as carbon fiber yarn, epoxy resin, and release paper through processes such as coating, hot pressing, cooling, laminating, and winding. A groove 9 is formed on the male mold 2, and a first insert 4 or a second insert 5 can be placed in the groove 9. Both the first insert 4 and the second insert 5 are adapted to the groove 9. A foamed support rib 6 is installed between the carbon fiber component 3 and the second insert 5. Both the first insert 4 and the second insert 5 are connected to the male mold 2 through a locking component 7. The foamed support rib 6 is made of materials such as epoxy resin, polyurethane, PET, PVC, and EPP that can be physically foamed or crosslinked and foamed. First, the first insert 4 is installed in the groove 9. After the carbon fiber component 3 is cured and formed, the first insert 4 is taken out. On the original mold, a foaming material is placed in the groove 9, and the second insert 5 is installed in the groove 9. Then, it is heated again to make the foaming material foam to form the foamed support rib 6, which is firmly combined with the carbon fiber component 3. This structure cancels the support rib injection molding process, saves the injection mold, reduces the injection mold cost and the injection process cost. At the same time, glue is no longer used, reducing environmental pollution, reducing production man-hours, saving the glue cost and improving the product quality.
[0025] The locking component 7 includes a clamping seat 705 fixedly connected to the outer side walls of the first insert 4 and the second insert 5 by screws, and a base 704 fixedly connected to the outer side wall of the male mold 2. A rotating rod 702 is rotatably connected to the base 704. A plug pin 701 is sleeved on the rotating rod 702. The rotating rod 702 has a prismatic structure, which is convenient for driving the plug pin 701 to rotate. A knob 703 is fixedly connected to the end of the rotating rod 702 away from the base 704. The plug pin 701 can rotate and insert into the clamping seat 705. After the first insert 4 or the second insert 5 is placed in the groove 9, the operator rotates the knob 703 to drive the rotating rod 702 to drive the plug pin 701 to rotate. The plug pin 701 rotates and inserts into the clamping seat 705, and the locking component 7 fixes the insert to the mold, preventing the insert from slipping out of the mold during the mold operation and affecting the effect of the final product.
[0026] Pull ring assemblies 8 are installed at the central positions of the outer side walls of the first insert 4 and the second insert 5. The setting of the pull ring assemblies 8 facilitates the operator to pull the inserts out of the mold after the inserts are used, increasing the practicability and convenience of the device.
[0027] The pull ring assembly 8 includes a first locking ring 801 and a second locking ring 802 that are threadedly connected. A fixing bead 803 is snap-fitted in the internal space formed by the first locking ring 801 and the second locking ring 802. A pull ring 804 is fixedly connected to the fixing bead 803. The pull ring 804 passes through the second locking ring 802. The first locking ring 801 is fixedly connected to a fixing plate 805, and the fixing plate 805 is fixedly connected to the outer side walls of the first insert block 4 and the second insert block 5. Through the threaded connection of the first locking ring 801 and the second locking ring 802, the pull ring 804 is detachably installed on the insert block, facilitating later replacement.
[0028] The bolt 701 is a fan-shaped structure with a gradually increasing thickness from one radius to another. As the thickness of the bolt 701 gradually increases, the bolt 701 is pressed tightly in the clamping seat 705 during the process of rotating the bolt 701. The connection method is simple, the operation is convenient, and the sealing is tight.
[0029] Working principle: The operator first installs the first insert block 4 into the groove 9. After curing the carbon fiber prepreg into the carbon fiber component 3, the first insert block 4 is taken out. On the original mold, foaming material is placed in the slot 9, and the second insert block 5 is installed into the slot 9. Then, it is heated again to make the foaming material foam to form the foaming support ribs 6, which are firmly combined with the carbon fiber component 3. This structure cancels the support rib injection molding process, saves the injection mold, reduces the injection mold cost and the injection process cost. At the same time, glue is no longer used, reducing environmental pollution, reducing the production man-hours, saving the glue cost and improving the product quality.
