Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of U-shaped beam demoulding, in particular to an auxiliary composite material U-shaped beam demoulding device. Background Art
[0002] After making composite products on the molding mold, although the molding mold surface is smooth and coated with a release agent, it is not always easy to remove the composite products from the mold. Practice shows that when demolding composite products, adhesion and adsorption must be overcome. Adhesion is generated after the resin matrix and the mold bonding surface are cured and formed; adsorption is the adsorption force generated under vacuum pressure when the prepreg is laid on the mold surface and the interface is in a nearly vacuum state.
[0003] During the demoulding process of U-beam composite products, special tools are required to pry along the edge of the product to separate it from the mold. In the specific area of the edge strip, springback often occurs due to the influence of material properties and heat treatment factors. If the operator applies uneven force or too much force, it may cause delamination damage to the R corner of the product, resulting in the scrapping of parts and increased costs. Utility Model Content

[0018] The embodiment of the present application provides an auxiliary composite material U-beam demoulding device, which effectively solves the rebound phenomenon that often occurs due to factors such as material properties and heat treatment. If the operator applies uneven force or too much force, it may cause delamination and damage to the R corner of the product, resulting in the scrapping of the part and increased costs. By increasing the use of the aluminum sheet body, the demoulding time is reduced, that is, the labor cost is reduced, and the probability of delamination of the R corner during demoulding is reduced, thereby reducing costs. At the same time, it can avoid prying directly from the edge of the part, damaging the surface of the part and causing delamination of the R corner of the part, thereby ensuring the R corner quality and molding quality of the U-beam during the manufacturing process.
[0019] Example
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the rebound phenomenon often occurs due to the influence of factors such as material properties and heat treatment. If the operator applies uneven force or too much force, it may cause delamination damage to the R corner of the product, resulting in the scrapping of parts and increased costs. The overall idea is as follows:
[0021] In view of the problems existing in the prior art, the utility model provides an auxiliary composite material U-beam demoulding device, including a molding tool 12, an aluminum sheet body 11 is arranged at the top of the molding tool 12, a prepreg layer on the surface of the aluminum sheet body 11 is laid with an outer skin 14, a honeycomb whole paving layer 16 adjacent to a honeycomb core 13, an edge of which is overlapped on the aluminum sheet body 11, a side end of the honeycomb whole paving layer 16 is connected to a quarter of the aluminum sheet body 11, and the remaining honeycomb whole paving layers 16 are not connected to the aluminum sheet body 11, and at the same time, the side ends of the inner skin 15 are overlapped to a half of the aluminum sheet body 11, and the prepreg edges exceeding the bottom edge of the aluminum sheet body 11 need to be manually cut and cured once U-shaped beam, after the prepreg is paved, auxiliary materials are placed and vacuum bags are made, and curing and molding are carried out according to the resin curing parameters. A honeycomb whole paving layer 16 is arranged at the top of the aluminum sheet body 11, an outer skin 14 is arranged at the top of the molding tool 12, an inner skin 15 is arranged at the top of the outer skin 14, and a honeycomb core 13 is fixedly installed at the bottom end of the inner skin 15. A tooling margin line 19 is arranged at the top of the molding tool 12, and an adhesive plate 22 is fixedly installed inside the molding tool 12. A tooling anti-slip belt score line 18 is arranged at the top of the molding tool 12, a tooling net scale line 21 is fixedly installed at the top of the molding tool 12, and a tooling edge strip 17 is fixedly installed at the top of the molding tool 12.
[0022] Working principle:
[0023] The first step is to use double-sided tape to bond the aluminum sheet body 11 to both sides of the forming tooling 12. The aluminum sheet body 11 is fixed to the adhesive plate 22, and the edge is temporarily fixed with a pressure-sensitive tape to prevent it from falling off. The surface of the aluminum sheet body 11 is not coated with a release agent, and is fixed by vacuum compaction. The aluminum sheet body 11 and the first layer of the whole paving layer are compacted at the same time, and the vacuum value is at least -0.08MPa. The skin is compacted for 15min during the compaction time. The surface prepreg layer of the aluminum sheet body 11 is paved with the outer skin 14, and the honeycomb whole paving layer 16 adjacent to the honeycomb core 13 is overlapped on the aluminum sheet body 11 at the edge. The side end of the honeycomb whole paving layer 16 intersects with a quarter of the aluminum sheet body 11, and the remaining honeycomb whole paving layers are overlapped. 16 do not intersect with the aluminum sheet body 11, and the side ends of the inner skin 15 are overlapped to one-half of the aluminum sheet body 11. The edges of the prepreg that exceed the bottom edge of the aluminum sheet body 11 need to be manually cut and cured to form a U-shaped beam. After the prepreg is paved, auxiliary materials are placed and vacuum bags are made. Curing and molding are carried out according to the resin curing parameters, and then the bags are opened and the auxiliary materials are removed. The demoulding tool is used to pry apart the edges of the aluminum sheet body 11 and the molding tool 12 around. The ductility of the aluminum sheet body 11 is used to drive the excess edge of the part to separate from the molding tool 12, so that the separation range is gradually expanded, and finally, lift up at both ends at the same time to make the part fall off from the inside of the molding tool 12.
[0024] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
