Description

Technical Field

[0001] This application relates to the technical field of composite product molding and demolding, and particularly to a demolding tooling. Background Art

[0002] When forming a composite skirt with a rotating shaft, a metal forming mandrel needs to be placed in the rotating shaft area of the skirt to ensure the size and concentricity of the rotating shaft area. After curing, the mandrel needs to be removed.

[0003] Most of the currently common demolding toolings are for demolding linear tubular products. For a skirt with a rotating shaft and a complex surface, during demolding, due to eccentric tension, it is relatively easy to cause difficulty in removing the rotating shaft forming mandrel, and there is even a risk of damaging the product or the mandrel. In addition, according to the traditional positioning method, generally, the curved surface of the skirt is used for support positioning. When the shaping curved surface of the skirt is large, the positioning tooling will be relatively complex, and different support toolings need to be made for different surfaces, which leads to an increase in cost and poor versatility.

[0004] Therefore, it is necessary to propose a demolding tooling with characteristics such as strong versatility, fast positioning, and efficient demolding.

[0005] It should be noted that the above content is not necessarily prior art and does not limit the patent protection scope of this application. Summary of the Invention

[0006] The embodiments of this application provide a demolding tooling to solve or alleviate the technical problems such as complex positioning tooling, slow positioning, and difficult mandrel demolding mentioned above.

[0007] According to an embodiment of this application, a demolding tooling is proposed. The demolding tooling is used for demolding a mandrel placed in the rotating shaft area during the molding of a skirt with a rotating shaft. It includes: a support frame, including support legs and a tabletop; a clamping and fixing platform, which is located on the tabletop; a clamping tooling, which includes a clamping part, a supporting part, and a base. The base is located on the clamping and fixing platform, and the clamping part and the supporting part are oppositely arranged on the base. The clamping part is used to fix the rotating shaft, and the supporting part is used to support the skirt.

[0008] The demolding tooling of the embodiments of the present application can solve the demolding problems of skirt plates with rotating shafts having different curved surface shapes, different lengths, and different positions; at the same time, it can achieve rapid positioning and efficient demolding. When the demolding tooling is used for demolding the mandrel placed in the rotating shaft area during the forming of the skirt plate with a rotating shaft, the clamping point of the clamping part of the clamping tooling is the rotating shaft, so that the rotating shaft can be tightly clamped, and further the concentricity between the demolded mandrel and the core-pulling tooling can be ensured, that is: the clamping site is selected in the rotating shaft area, and the axes of the rotating shaft skirt plates with different profiles are linearly unified. Even if the skirt plate is deformed, the axis can be positioned by fixing the rotating shaft area of the product on the clamping tooling to ensure that the mandrel is always concentric with the core-pulling tooling during demolding. The installation position and size of the clamping tooling are adapted to the rotating shaft, so that the demolding tooling can simultaneously meet the interchange of the clamping toolings of skirt plates with different shapes (different lengths, different curved surfaces, different rotating shaft positions), and further realize the demolding of skirt plates with rotating shafts of different specifications. In short, setting the clamping area in the linear rotating shaft area facilitates the demolding tooling to achieve the axial positioning of the skirt plate rotating shaft, and because the skirt plates with rotating shafts are coaxial in the axial direction, selecting the positioning in the rotating shaft area avoids setting the support tooling in the curved surface area of the product, thereby reducing and simplifying the support range of the tooling, making the tooling support more concise; on the other hand, by replacing the movable product clamping tooling, the demolding tooling for different-shaped rotating shafts can be realized, that is, the demolding tooling has strong versatility, and further reduces the preparation cost of the demolding tooling.

[0009] According to an embodiment of the present application, the flatness of the tabletop ≤ 0.5 mm.

[0010] According to an embodiment of the present application, a guide rail chute is provided on the clamping and fixing platform, and the base is slidably connected to the guide rail chute to adjust the position of the clamping tooling.

[0011] According to an embodiment of the present application, the demolding tooling further includes: a demolding stop block, the demolding stop block is arranged on the clamping and fixing platform along the demolding direction of the mandrel, and the demolding stop block is provided with a groove for placing the mandrel.

[0012] According to an embodiment of the present application, the demolding tooling further includes: a drawing guiding mechanism, the drawing guiding mechanism includes a first guiding block and a second guiding block; the first guiding block is located on the side of the demolding stop block away from the clamping tooling and is connected to the clamping and fixing platform; the second guiding block is located on the side of the first guiding block away from the demolding stop block and is connected to the tabletop.

[0013] According to an embodiment of the present application, the first guiding block includes a first guiding block base and an upper pressing block which are oppositely arranged. The first guiding block base is provided with a first placement groove, and the upper pressing block is provided with a second placement groove which is oppositely arranged with the first placement groove.

[0014] According to an embodiment of the present application, a bushing is further arranged between the first guiding block base and the upper pressing block, and the bushing is of a through-hole structure.

[0015] According to an embodiment of the present application, the demolding tooling further includes a pulling mechanism. The pulling mechanism includes a connecting head and a power mechanism. The connecting head is connected to the core shaft. When demolding the core shaft placed in the rotating shaft area during the molding of the skirt plate with a rotating shaft, the clamping tooling makes the core shaft concentric with the pulling mechanism.

[0016] According to an embodiment of the present application, the adapter includes a third guiding block which has a groove. The core shaft passes through the groove and is fixedly connected to the third guiding block by a nut.

[0017] According to an embodiment of the present application, the demolding tooling further includes a transfer shaft. One end of the transfer shaft is connected to the connecting head, and the other end is connected to the core shaft. Description of the Drawings

[0021] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings. In the drawings, for clarity, the dimensions of layers, regions, elements, and their relative dimensions may be exaggerated.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] It should be understood that when an element or layer is referred to as "on...", "adjacent to...", "connected to" or "coupled to" another element or layer, it can be directly on, adjacent to, connected or coupled to the other element or layer, or there may be intervening elements or layers.

It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Therefore, without departing from the teachings of the present application, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part. And when discussing the second element, component, region, layer, or part, it does not mean that the present application necessarily has a first element, component, region, layer, or part.

[0023] In this application, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that these terms can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily limit to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] Most of the currently common demolding tooling is for demolding linear tubular products. There are no clear positioning requirements for the skirt plate with a rotating shaft and a complex surface, and it is difficult to ensure that the mandrel and the demolding force are on the same axis. That is, during actual demolding, it will cause eccentric tension, which not only makes it difficult to demold the rotating shaft forming mandrel, but also there is a risk of damaging the product or the mandrel. At the same time, according to the traditional positioning method, generally, the curved surface of the skirt plate is used for support positioning. The shaping curved surface of the skirt plate is relatively large, the positioning tooling will be more complex, and different support toolings need to be made for different surfaces, resulting in an increase in cost and poor versatility.

[0026] Accordingly, this application proposes a demolding tooling, which is used for demolding the mandrel placed in the rotating shaft area during the forming of the skirt plate with a rotating shaft. Refer to Figure 1 and Figure 2 , this demolding tooling includes: a support frame 1, the support frame 1 includes support legs 11 and a table top 12; a clamping and fixing platform 2, the clamping and fixing platform 2 is located on the table top 12; a clamping tooling 3, the clamping tooling 3 includes a clamping part 31, a support part 32 and a base 33, the base 33 is located on the clamping and fixing platform 2, the clamping part 31 and the support part 32 are oppositely arranged on the base 33, the clamping part 31 is used for fixing the rotating shaft, and the support part 32 is used for supporting the skirt plate.

[0027] The demolding tooling of the embodiments of the present application can solve the demolding problems of skirt plates with rotating shafts having different curved surface shapes, different lengths, and different positions; at the same time, rapid positioning and efficient demolding can be achieved. When the demolding tooling is used for demolding the mandrel placed in the rotating shaft area during the forming of the skirt plate with a rotating shaft, the clamping point of the clamping part of the clamping tooling is the rotating shaft, so that the rotating shaft can be pressed tightly, and further the concentricity between the demolded mandrel and the core-pulling tooling can be achieved, that is: the clamping site is selected in the rotating shaft area, and the axes of the rotating shaft skirt plates with different profiles are linearly unified. Even if the skirt plate is deformed, the axial center positioning can be realized by fixing the rotating shaft area of the product on the clamping tooling, so as to ensure that the mandrel is always concentric with the core-pulling tooling during demolding. The installation position and size of the clamping tooling are adapted to the rotating shaft, so that the demolding tooling can simultaneously meet the interchange of the clamping toolings of skirt plates with different shapes (different lengths, different curved surfaces, different rotating shaft positions), and further realize the demolding of skirt plates with rotating shafts of different specifications. In short, setting the clamping area in the linear rotating shaft area facilitates the demolding tooling to realize the axial positioning of the skirt plate rotating shaft, and because the skirt plates with rotating shafts are coaxial in the axial direction, selecting the positioning in the rotating shaft area avoids setting the support tooling in the curved surface area of the product, thereby reducing and simplifying the support range of the tooling, making the tooling support more concise; on the other hand, by replacing the movable product clamping tooling, the demolding tooling for different-shaped rotating shafts can be realized, that is, the demolding tooling has strong versatility, thereby reducing the preparation cost of the demolding tooling.

[0028] In some embodiments, the support frame 1 includes support legs 11 and a tabletop 12. Among them, the support legs 11 and the tabletop 12 can be fixed by bolts.

[0029] Further, the flatness of the tabletop 12 ≤ 0.5 mm. This can ensure the stability of other components located on the tabletop.

[0030] The term flatness refers to: the deviation of the macroscopic uneven height of the tabletop relative to the ideal plane.

[0031] Optionally, positioning pin holes are provided on the tabletop. This can improve the position accuracy of other components installed thereon, and further ensure the concentricity between the clamping tooling and the mandrel during demolding.

[0032] In some embodiments, the clamping and fixing platform is located on the tabletop. The clamping and fixing platform is fixedly connected to the tabletop by bolts.

[0033] Further, a guide rail chute is provided on the clamping and fixing platform 2, and the base of the clamping tooling is slidably connected to the guide rail chute to adjust the position of the clamping tooling. That is: the clamping tooling can move along the guide rail chute on the clamping and fixing platform. In this way, the clamping tooling can adapt to the fixing of skirt plates with different lengths and different rotating shaft positions. During demolding, as long as the position of the clamping tooling is moved, the fixing of the rotating shafts at different positions can be completed.

[0034] In some embodiments, there is a clamping tooling 3, which includes a clamping part 31, a supporting part 32 and a base 33. The base 33 is located on the clamping and fixing platform 2. The clamping part 31 and the supporting part 32 are oppositely arranged on the base 33. The clamping part 31 is used to fix the rotating shaft, and the supporting part 32 is used to support the skirt plate. When demolding, the gap between the supporting part 32 and the skirt plate can be padded tightly with a silicone sheet. On the one hand, this can fix the skirt plate, and on the other hand, it can reduce the risk of pinching when the skirt plate is in direct contact with the supporting part. Similarly, the gap between the clamping part 31 and the rotating shaft can be padded tightly with a silicone sheet. On the one hand, this can fix the rotating shaft, and on the other hand, it can reduce the risk of pinching when the rotating shaft is in direct contact with the clamping part.

[0035] In some embodiments, the clamping tooling is fixed to the clamping and fixing platform by nuts.

[0036] In some embodiments, the demolding tooling further includes a demolding stopper 4. The demolding stopper 4 is arranged on the clamping and fixing platform 2 along the demolding direction of the mandrel. The demolding stopper 4 is provided with a groove for placing the mandrel. This can reduce the risk of the skirt plate slipping axially during demolding.

[0037] Further, the demolding stopper and the clamping and fixing platform are fixedly connected by bolts.

[0038] In some embodiments, the demolding tooling further includes a drawing guiding mechanism 5. The drawing guiding mechanism 5 includes a first guiding block 51 and a second guiding block 52. The first guiding block 51 is located on the side of the demolding stopper 4 away from the clamping tooling 3, and the second guiding block 52 is on the side of the first guiding block 51 away from the demolding stopper 4. This can promote the mandrel to move axially during demolding.

[0039] Optionally, the first guiding block is fixedly connected to the clamping and fixing platform by nuts.

[0040] Optionally, the second guiding block is fixedly connected to the tabletop by nuts.

[0041] In some embodiments, referring to Figure 3 , the first guiding block 51 includes a first guiding base 510 and an upper pressing block 511 which are oppositely arranged. The first guiding block base 510 is provided with a first placement groove, and the upper pressing block is provided with a second placement groove opposite to the first placement groove. The first guiding block base 510 is connected to the clamping and fixing platform 2, and the first guiding block base 510 and the upper pressing block 511 are fixed by a buckle.

[0042] In some embodiments, the second guiding block 52 has a U-shaped groove. In this way, the mandrel can be placed in the U-shaped groove to reduce the non-axial movement of the mandrel.

[0043] In some embodiments, a bushing 512 is further disposed between the first guide block base 510 and the upper pressing block 511. The bushing has a through-hole structure. In this way, the mandrel can pass through the bushing, thereby reducing the non-axial movement of the mandrel. In addition, different mandrel sizes can be guided by replacing the bushing (the base and the upper pressing block do not need to be replaced).

[0044] In some embodiments, the demolding tooling further includes a pulling mechanism 6. The pulling mechanism includes an adapter 61 and a power mechanism 62. The adapter 61 is connected to the mandrel. When demolding the mandrel placed in the rotating shaft area during the molding of the skirt plate with a rotating shaft, the clamping tooling makes the mandrel concentric with the pulling mechanism. In this way, the pulling mechanism can realize the demolding of the mandrel, and the clamping tooling can make the mandrel concentric with the pulling mechanism.

[0045] In some embodiments, referring to Figure 3 , the adapter 61 includes a third guide block 611. The third guide block 611 has a groove. The mandrel passes through the groove of the third guide block 611 and is fixedly connected to the third guide block 611 by a nut.

[0046] In some embodiments, the adapter is fixedly connected to the power mechanism by a nut.

[0047] In some embodiments, the power mechanism includes a hydraulic power or a mechanical oil cylinder.

[0048] In some embodiments, the demolding tooling further includes an adapter shaft 7. One end of the adapter shaft 7 is connected to the connector 61, and the other end is connected to the mandrel. The provision of the adapter shaft can lengthen the mandrel to facilitate the pulling of the pulling mechanism. In addition, the provision of the adapter shaft can meet the connection of mandrels of different sizes to the pulling mechanism, that is, by changing the size of the bushing to match different adapter shafts.

[0049] In some embodiments, the mandrel is connected to the adapter shaft by bolts.

[0050] In some embodiments, the connection between the adapter shaft and the connector is fixedly connected by bolts and gaskets.

[0051] It can be understood that one end of the adapter shaft is connected to the mandrel. When connecting, the adapter shaft can pass through the bushing and be located in the U-shaped groove of the second guide block. In this way, the first guide block and the second guide block can reduce the non-axial movement of the adapter shaft. In addition, when the adapter shaft is connected to the connector, the adapter shaft passes through the groove of the third guide block and is fixedly connected to the third guide block.

[0052] In summary, the clamping method of the demolding tooling product of the present application is simple and the cost is relatively low: the demolding tooling can adapt to the positioning of different skirt plates with rotating shafts; the mandrel cross-section along the rotating shaft area of the same product is the same, which is more convenient for processing; for skirt plate products with different-sized rotating shafts, only the movable product clamping tooling needs to be replaced to achieve universality, and the transformation cost of the tooling is very low. The clamping speed is fast and the efficiency is high: the positioning accuracy of the tooling itself is high. During operation, only the rotating shaft area needs to be compacted to achieve rapid positioning, and the concentricity between the demolding mandrel and the demolding mechanism is ensured.

[0053] For the embodiments of the present application, refer to Figure 4 and Figure 5 , and a demolding method for a skirt plate 8 with a rotating shaft using the demolding tooling of the present application is provided. The method includes the following steps: S1: Fix the product Loosen the bolts between the slider in the guide groove of the product clamping and fixing platform and the movable product clamping tooling, and adjust the position of the clamping tooling so that each clamping tooling corresponds to the skirt plate rotating shaft one by one. Specifically, load the skirt plate product into the movable clamping tooling, that is, make the clamping part press the rotating shaft and make the supporting part support the skirt plate; adjust the skirt plate in the length direction of the skirt plate so that the skirt plate is aligned with the demolding stopper; fix the clamping tooling to the clamping and fixing platform; fix the skirt plate rotating shaft area to the clamping part; fill the gap between the skirt plate curved surface and the tooling support contact surface with gaskets.

[0054] S2: Replace the insert sleeve on the drawing shaft guiding mechanism so that the adapter shaft matches the insert sleeve; Pass the adapter shaft through the insert sleeve of the drawing guiding mechanism and fix the insert sleeve.

[0055] S3: Connect the end of the adapter shaft and the demolding mandrel together by bolts.

[0056] S4: Connect the drawing mechanism. Specifically: One end of the mandrel passes through the third guiding block groove of the adapter, and then the adapter shaft and the connecting head are fixed by nuts.

[0057] Start the power mechanism, and move the adapter of the drawing mechanism to drive the movable mandrel to move towards the skirt plate side.

[0058] Then, first straighten the adapter shaft with a relatively small pulling force (such as 0.3 - 1.0 Mpa), adjust the position of the insert sleeve on the drawing shaft guiding mechanism, and fix it.

[0059] Continue to increase the pulling force of the power mechanism until the mandrel is separated from the product.

[0060] S5: Loosen the movable product clamping tooling and take out the skirt plate.
