Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of demolding equipment, in particular to a pneumatic composite body of revolution demolding device. BACKGROUND

[0002] At present, there are many curing forming processes of fiber reinforced materials, mainly including hand lay-up forming, spray forming, mold pressing forming and winding forming, etc. Among them, winding forming is more widely used due to the advantages of high specific strength, good reliability, low cost and high production efficiency. The working process of fiber winding forming process is to wrap release cloth on the outer surface of the core mold, then wrap rubber parts on the outer surface of the release cloth, then wrap the cloth bag, fiber and other reinforcing materials soaked in resin glue on the surface of the rotary core mold according to a certain rule, and then make different sizes and shapes of rotary winding products through heat curing. However, in the demolding process, the mold and the outer surface of the release cloth wrapped around the fiber winding product need to be separated, but the friction between the release cloth and the rubber part is particularly large during the demolding process, so the demolding process is very difficult. Therefore, in most cases, the composite rotary product formed by winding needs to use a special demolding device. The main reason is that some rotary winding products wrap release cloth on the outer surface of the mold, wrap rubber parts on the outer surface of the release cloth, and then wrap carbon fiber on the outer surface of the rubber part, and then solidify to obtain the fiber winding product. However, in the demolding process, the mold and the release cloth wrapped on the outer surface of the mold will be separated from the fiber winding product, and because the friction between the release cloth and the rubber part is particularly large during the demolding process, it is difficult to separate the release cloth from the rubber part.

[0003] Traditional composite core molds are divided into disposable core molds and reusable core molds, among which disposable core molds are divided into breakable core molds and soluble core molds. For composite rotary bodies, the general mold structure is complex, the operation convenience is poor, and the production efficiency is low. A large mechanical external force is needed to complete demolding, which may cause the mold to deform, and even damage the mold in severe cases. It cannot be applied to composite rotary bodies of different sizes and shapes.

[0004] Therefore, the difficulty of demolding carbon fiber parts has always been a problem for us. The existing demolding methods mostly use simple mechanical demolding or divide the mold into core blocks. Among them, the simple mechanical demolding method is easy to scratch the mold and the product, reduces the service life of the mold, and is not easy to operate, especially after the product is cured and formed, a thin layer of resin is easily attached to the surface of the mold. The simple mechanical demolding method is not easy to find the point of force, which is not conducive to demolding, and the uneven stress on the product also easily damages the product. The mold divided into core blocks is difficult to assemble and position when the product is laid and cured. SUMMARY

Through the above design, this embodiment has good overall versatility, simple structure, easy operation and high production efficiency, and provides a solution to the problem of difficult demoulding of winding molding.

[0029] Specifically, the mounting base includes a base 1 and a frame 2. The frame 2 is installed on the upper end of the base 1, and the demolding assembly is installed in the frame 2. The base 1 supports the whole body, and the frame 2 limits the whole body, thereby improving the stability during the demolding process.

[0030] The rack 2 comprises two oppositely arranged limiting racks, the air driving module 5, the action module 7, the upper clamping element and the lower clamping element are arranged and installed between the two limiting racks in sequence, and then the above elements are limited between the two limiting racks to avoid instability in the demolding process.

[0031] The air driving module 5 is provided with a first positioning clamping plate 4 on the side away from the action module 7, and is provided with an air driving positioning clamping plate 6 on the side away from the first positioning clamping plate 4, the first positioning clamping plate 4 and the air driving positioning clamping plate 6 are respectively limited at both ends of the air driving module 5, and then the first positioning clamping plate 4, the air driving positioning clamping plate 6 and the two limiting racks are respectively located around the air driving module 5, which can effectively position the air driving module 5, prevent displacement of the air driving module 5 during work, and affect the normal progress of the demolding process.

[0034] The action module 7 is a pneumatic piston module, which comprises a reset spring 701, a pneumatic piston rod 702 and a piston shell 703. The piston shell 703 is installed on the mounting seat, and the pneumatic piston rod 702 is installed in the piston shell 703. The pneumatic piston rod 702 can be extended and retracted through one side of the piston shell 703. The reset spring 701 is sleeved on the outer periphery of the pneumatic piston rod 702. One end of the reset spring 701 is installed on the end of the pneumatic piston rod 702 away from the upper clamping element, and the other end of the reset spring 701 is installed on the inner wall of the piston shell 703 close to the upper clamping element. A piston valve 13 is arranged on the side wall of the piston shell 703, connected with the air pipe 3, and used to control whether the air is supplied to the piston shell 703 or not, so as to control the extension and retraction of the pneumatic piston rod 702. When the pneumatic piston rod 702 is extended under the action of the air cylinder, the reset spring 701 is elongated. In this process, the pneumatic piston rod 702 provides power for the core mold 904, so as to push the core mold 904 and the rotary body product 903 apart. When the demolding work is completed, the air driving module 5 stops supplying air to the air cylinder. At this time, the reset spring 701 is in a stretched state. Under the action of the elastic restoring force of the reset spring 701, the pneumatic piston rod 702 is reset. The automatic reset function of the pneumatic piston rod 702 greatly improves the production efficiency of the embodiment.

[0035] The piston shell 703 is provided with a boss on the side wall for installing the reset spring 701, and the pneumatic piston rod 702 is provided with a boss on the end for installing the reset spring 701. The bosses are provided with through holes for connecting the reset spring 701, so as to realize the stable connection between the spring and the piston shell 703 and between the spring and the pneumatic piston rod 702.

[0036] The upper clamping element comprises an upper end cover 901 and an upper clamping plate 902, the upper clamping plate 902 is installed on the upper end cover 901 on the side close to the rotary body product 903, and the upper clamping plate 902 is provided with an upper clamping hole, which can be used for the extension of the pneumatic piston rod 702; the lower clamping element comprises a lower end cover 906 and a lower clamping plate 905, the lower clamping plate 905 is installed on the lower end cover 906 on the side close to the rotary body product 903, and the lower clamping plate 905 is provided with a lower clamping hole, which can be used for limiting the rotary body product 903 while ensuring that the core mold 904 can pass through; the two ends of the rotary body product 903 can abut against the end faces of the upper clamping plate 902 and the lower clamping plate 905, and one end of the core mold 904 can extend out through the lower clamping hole, thereby ensuring that the core mold 904 and the rotary body product 903 can move axially relative to each other when the pneumatic piston rod 702 acts on one end of the core mold 904, and demolding is realized. The rotary body product 903 is limited by the upper clamping plate 902 and the lower clamping plate 905, and at the same time, a closed space through which gas can pass is formed between the upper end cover 901, the lower end cover 906, the outer wall of the core mold 904 and the inner wall of the rotary body product 903, so that the gas can enter the gap between the core mold 904 and the rotary body product 903. By replacing the upper clamping plate 902 and the lower clamping plate 905 of different shapes and sizes, the core mold 904 and the rotary body product 903 of different sizes and shapes can be clamped between the upper clamping plate 902 and the lower clamping plate 905, thereby enabling the embodiment to be applicable to the demolding work of rotary body products 903 of different sizes and shapes.

[0037] The side wall of the upper end cover 901 is provided with a gas valve 907, the gas driving module 5 is connected with the gas valve 907 through the air pipe 3, and the opening and closing of the gas valve 907 is used to control whether the gas enters the upper end cover 901 or not. The gas driving module 5 can pass the gas into the upper end cover 901 through the air pipe 3 and the gas valve 907, and make the gas enter the gap between the rotary body product 903 and the core mold 904, so that the rotary body product 903 and the surface of the core mold 904 generate a separation force, thereby helping the rotary body product 903 to easily separate from the surface of the core mold 904. When the upper end cover 901 is inflated through the gas valve 907, the input gas is first pressed into the upper end cover 901, and the gradually increasing gas pressure uniformly acts on the core mold 904, thereby providing power for the axial demolding of the core mold 904. At the same time, the gas filled into the upper end cover 901 also flows into the gap between the core mold 904 and the rotary body product 903, so that the core mold 904 and the rotary body product 903 attached to the surface are separated, and the friction is reduced to a certain extent, thereby providing favorable conditions for subsequent demolding work.

[0038] The specific working process of the embodiment is as follows:

[0039] First, the prepared rotary body product 903 is prepared and placed between the upper clamping plate 902 and the lower clamping plate 905; then the upper end cover 901 is inflated, the air pump 11 is used to supply air to the air drive module 5, the air is introduced into the closed space outside the core mold 904 through the air pipe 3, the air pressure inside the closed space is increased, so that the separation force between the rotary body product 903 and the surface of the core mold 904 is generated, but the force generated by inflation alone may not be enough to make the core mold 904 be pushed out, so the pneumatic piston rod 702 is needed; start the air cylinder, the air cylinder drives the pneumatic piston rod 702 to further separate the core mold 904 from the rotary body product 903; after demolding is completed, stop the air supply and the advancement of the pneumatic piston rod 702, and take out the rotary body product 903, at this time the pneumatic piston rod 702 will be automatically reset under the action of the reset spring 701, and when the reset is completed, the next demolding can be directly performed. In addition, the embodiment can be applied to the demolding of products of different sizes and shapes by replacing the upper clamping plate 902 and the lower clamping plate 905 of different sizes and shapes, replacing the air cylinder of different strokes, and changing the positions of the positioning clamping plates, and can also be applied to the demolding of products of different lengths.

In summary, the content of the present application should not be understood as a limitation of the present application.
