Description

Technical Field

[0001] This application relates to the field of large mold stripping technology, and in particular to an external mold avoidance support mechanism. Background Technology

[0002] Large stamping dies play a vital role in modern industrial production, widely used in the forming and processing of metal sheets in industries such as automobiles and home appliances. As the manufacturing industry's demands for production efficiency and product quality continue to rise, stamping die technology is constantly advancing, gradually moving towards higher efficiency and automation. However, in the stamping process, the workpiece stripping stage has always been one of the key factors restricting the improvement of production efficiency. Traditional stamping dies mainly rely on manual labor or third-party tools to complete workpiece stripping. This method is not only inefficient but also poses safety hazards, making it difficult to meet the demands of modern industry for automated production.

[0003] To solve the problem of workpiece ejection, the existing technology usually involves installing a driving device, such as a cylinder or hydraulic cylinder, inside the mold to use driving force to eject the workpiece from the mold. However, this method has high economic and design costs and requires significant modifications to the mold structure, resulting in long mold design cycles and inconvenient maintenance.

[0004] Therefore, how to achieve automated workpiece unloading while reducing economic and design costs has become an urgent technical challenge. Utility Model Content

[0005] In order to achieve automated workpiece unloading while reducing economic and design costs, this application provides an external mold avoidance support mechanism.

[0006] The technical solution of the external mold avoidance support mechanism provided in this application is as follows:

[0007] An external mold clearance support mechanism includes a connector and a support member; the support member is movably connected to one end of the connector, the connector has a receiving groove, the support member can be received in the receiving groove, and the support member can extend out of the receiving groove after being moved relative to the connector, forming an angle with the connector; the end of the connector away from the support member is connected to the upper mold.

[0008] By adopting the above technical solution, during stripping, the support component is first stored in the receiving groove, then the upper mold is lowered, and the support component is extended into the lower mold. When the support component reaches a position below the workpiece, it is released from the receiving groove, so that a certain angle is formed between the support component and the connecting component, allowing the support component to reach below the workpiece. Then, the upper mold is moved upward, and the movement of the upper mold drives the connecting component and the support component to move upward, bringing the workpiece out during the upward movement, thereby realizing automatic stripping of the workpiece, while having low economic and design costs.

[0009] Optionally, the support member is rotatably connected to the connector; the connector is provided with a partition, which is used to abut against the support member after the support member has rotated a certain angle relative to the connector; the certain angle is between 80° and 160°.

[0010] By adopting the above technical solution, during the downward movement of the connecting part driven by the upper mold, the supporting part first abuts against the workpiece on the surface away from the connecting part. During the subsequent movement, the supporting part gradually rotates into the receiving groove under the contact of the workpiece. Then, when the connecting part moves to a certain extent relative to the workpiece, the supporting part loses the contact of the workpiece and, under its own gravity, rotates out of the receiving groove and moves to below the workpiece, where it is positioned in a specific location by the partition. Finally, the upper mold moves upward, and the workpiece is carried out using the support of the supporting part. The above structure is simple and easy to operate.

[0011] Optionally, the storage groove is formed on the side of the connector near the support member, and there is a gap between the end face of the storage groove away from the upper mold and the end face of the connector; the support member is provided with a rotating shaft, and the rotating shaft is rotatably connected to the groove wall of the storage groove; the portion of the connector located at the gap acts as the partition.

[0012] By adopting the above technical solution, the rotating shaft is placed in the storage, and the part of the connector located at the interval acts as a partition, thereby improving the integration of each component and reducing the space requirements of the support mechanism.

[0013] Optionally, the connector is hinged to the upper mold, and the rotation axis of the connector relative to the upper mold is parallel to and located in the same plane as the rotation axis of the support relative to the connector.

[0014] By adopting the above technical solution, the position of the connector can be adjusted according to the size of the workpiece, thereby improving the flexibility of the support mechanism.

[0015] Optionally, the support member has friction elements on the surface that abuts against the workpiece.

[0016] By adopting the above technical solution, the friction between the support component and the workpiece is increased, the contact stability between the support mechanism and the workpiece is improved, and the support mechanism can more stably remove the workpiece.

[0017] Optionally, the friction element is a rubber sleeve, which is fitted over the support element.

[0018] By adopting the above technical solution, the rubber sleeve can be replaced after it is damaged, thus extending the service life of the support mechanism.

[0019] Optionally, the friction element is a plurality of anti-slip strips, which extend along the width direction of the anti-slip strips and are arranged at intervals along the length direction of the support element.

[0020] Optionally, the support member is a movable rod of a telescopic rod.

[0021] By adopting the above technical solution, compared with the above hinge method, the space requirement is lower and the convenience of material unloading is improved.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By connecting the connector to the upper mold and movably connecting the support component at the end of the connector away from the upper mold, the upper mold moves up and down, driving the connector and support component to move up and down. During stripping, the upper mold moves down first, causing the support component to move below the workpiece. Then the upper mold moves up, using the support component to carry the workpiece out. This method achieves automatic stripping at a low cost.

[0024] 2. By rotating the support member to the connector, and having the portion of the connector located between the end wall of the storage groove and the end face of the connector act as a partition, the structure is simple and reduces the space requirements.

[0025] 3. By installing anti-slip components on the support components, the stress stability of the support mechanism when supporting the workpiece movement is improved. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses an external mold avoidance support mechanism.

[0033] Example 1

[0034] Reference Figure 1 An external mold support mechanism includes a connector 1 and a support 2. The support 2 is movably connected to one end of the connector 1. The connector 1 has a receiving groove 11, in which the support 2 can be received. After the support 2 moves relative to the connector 1, it can extend out of the receiving groove 11, forming an angle with the connector 1. The end of the connector 1 away from the support 2 is connected to the upper mold 3. During stripping, the support 2 is first received in the receiving groove 11, then the upper mold 3 is lowered, extending the support 2 into the lower mold. When the support 2 reaches a position below the workpiece, it is released from the receiving groove 11, forming a certain angle between the support 2 and the connector 1, thus allowing the support 2 to reach below the workpiece. Then, the upper mold 3 is moved upward, and the movement of the upper mold 3 drives the connecting part 1 and the supporting part 2 to move upward. During the upward movement, the workpiece is brought out, thereby realizing the automatic unloading of the workpiece, while the economy and design cost are low.

[0035] Specifically, the support member 2 is rotatably connected to the connector 1. The connector 1 is provided with a partition 12, which is used to abut against the support member 2 after the support member 2 has rotated a certain angle relative to the connector 1. The certain angle is between 80° and 160°.

[0036] In this embodiment, the aforementioned angle is 90° to facilitate the stable removal of the workpiece.

[0037] In this embodiment, the receiving groove 11 is formed on the side of the connector 1 near the support member 2, and there is a gap between the end face of the receiving groove 11 away from the upper mold 3 and the end face of the connector 1. The support member 2 is provided with a rotating shaft 21, which is rotatably connected to the groove wall of the receiving groove 11. The portion of the connector 1 located at the gap acts as a partition 12. Thus, the rotating shaft 21 is placed in the receiving groove, and the portion of the connector 1 located at the gap acts as a partition 12, improving the integration of the components and reducing the space requirements of the support mechanism.

[0038] In other embodiments, the support member 2 may also be a movable rod of the telescopic rod to reduce the space requirements of the support mechanism.

[0039] The implementation principle of Example 1 is as follows: Under normal conditions, the support member 2 forms a 90° angle with the connecting member 1 under its own weight and the blocking effect of the partition part 12. During unloading, the upper mold 3 first drives the connecting member 1 to move downward. During the downward movement, the support member 2 first abuts against the upper surface of the workpiece. Under the force of the workpiece, the support member 2 gradually rotates into the receiving groove 11 to avoid the workpiece. After the connecting member 1 moves downward to a certain extent, the support member 2 loses the workpiece's restraint and rotates again under its own weight to abut against the partition part 12. Then, the upper mold 3 drives the connecting member 1 and the support member 2 to move upward. During the upward movement, the support member 2 abuts against the lower surface of the workpiece. The workpiece moves upward under the action of the support member 2, thereby realizing automatic unloading of the workpiece. At the same time, the above structure is relatively simple, and the economic and design costs are low.

[0040] Example 2

[0041] Reference Figure 2 The difference between this embodiment and Embodiment 1 is that the connecting member 1 is hinged to the upper mold 3, and the rotation axis 21 of the connecting member 1 relative to the upper mold 3 is parallel to and located in the same plane as the rotation axis 21 of the supporting member 2 relative to the connecting member 1. This allows the connecting member 1 to rotate relative to the upper mold 3, making it suitable for workpieces of more sizes or lower molds of more design shapes, thus improving the flexibility of the supporting mechanism.

[0042] Example 3

[0043] Reference Figure 3 The difference between this embodiment and Embodiment 2 is that the surface of the support member 2 that abuts against the workpiece is provided with a friction element 22. This increases the friction between the support member 2 and the workpiece, improves the contact stability between the support mechanism and the workpiece, and facilitates the support mechanism to more stably remove the workpiece.

[0044] In this embodiment, the friction element 22 is a rubber sleeve, which is fitted outside the support element 2. While providing a good anti-slip effect, it is also easy to replace after wear, thus extending the service life of the support mechanism.

[0045] Example 4

[0046] Reference Figure 4 The difference between this embodiment and embodiment 3 is that the friction element 22 consists of multiple anti-slip strips, which extend along the width direction of the anti-slip strips and are arranged at intervals along the length direction of the support element 2.

[0047] In this embodiment, the friction element 22 and the support element 2 are integrally formed to ensure the connection stability between the friction element 22 and the support element 2.

[0048] It is understood that in this embodiment, the friction member 22 may also be formed by opening multiple grooves on the surface of the support member 2 and utilizing the protrusions between adjacent grooves.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
