And it clings to the mold to complete the spinning process of the part.

[0003] In the prior art, after the spinning process of the product is completed, after the fixture releases the product, the product is then pulled out from the mold manually. However, when taking out the product in this way, a relatively large force is required to pull out the product located in the material clamping area, resulting in inconvenient material taking, time-consuming and laborious, and it is not easy to take the material quickly. Summary of the Utility Model

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts fall within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] Please refer to the Figures 1-3 drawings. A fixture of the present invention with an automatic material discharging function includes a material clamping component 1, a material supporting component 2, and a material discharging component 3. The material clamping component 1 includes a clamping block 11, and a material clamping cavity 12 is formed by surrounding the clamping block 11; the material supporting component 2 is arranged in the material clamping cavity 12, and a material placing cavity is formed in the area between the material supporting component 2 and the clamping block 11; the material discharging component 3 is arranged in the material placing cavity; wherein, the material discharging component 3 includes an elastic member 31 and a material discharging assembly 32; the elastic member 31 is sleeved on the material supporting component 2, and one end of the elastic member 31 is connected to the material discharging assembly 32.

[0038] Among them, the material clamping component 1 is used to tighten and loosen the product 5. When the product 5 is ready for spinning processing, the clamping block 11 of the material clamping component 1 clamps the product 5; when the product 5 after spinning processing needs to be taken out, the clamping block 11 of the material clamping component 1 loosens the product 5.

[0039] The material supporting component 2 is used to insert into the inner cavity of the product 5 to provide a supporting force for the product 5, and at the same time is equivalent to a mold to provide a basis for the shape of the product 5 during spinning, ensuring the spinning quality.

[0040] The material discharging component 3 is used to push the product 5 after spinning processing a certain distance away from the material supporting component 2, facilitating the operator to take the spun product 5.

[0041] For the fixture with a material discharging function in this embodiment, the operation process is as follows: When the product 5 needs to be spun processed, first insert the product 5 onto the material supporting component 2 so that the product 5 is embedded in a certain position in the material placing cavity. During the process of inserting the product 5 onto the material supporting component 2, the product 5 pushes the material discharging assembly 32 to move in the Y direction, making the elastic member 31 in a compressed state. After the product 5 is inserted into a certain position in the material placing cavity, the clamping block 11 of the material clamping component 1 clamps the product 5 to ensure the stability of the product 5 placement. Then spin the product 5 according to the specific shape of the material supporting component 2 until the spinning processing is completed; the clamping block 11 of the material clamping component 1 loosens the product 5, and the material discharging assembly 32 is subjected to the acting force of the elastic member 31 in the X direction, so that the material discharging assembly 32 pushes the product 5 embedded in the material placing cavity a certain distance in the X direction, realizing the material discharging function. Through this setting, the ease of taking out the product 5 can be effectively improved, the labor-saving and convenience of taking materials can be realized, the material taking time can be saved, and thus the overall processing efficiency of the product can be improved.

[0042] Preferably, the elastic member 31 is a spring elastic member 31. The elastic member has a compressive elastic force in the X direction. Specifically, the compressive elastic force of the elastic member can provide a compressive elastic force in the X direction to the product. When the product loses the clamping member or other fixed forces, the elastic member will eject the product. Through this setting, the elastic member 31 has a simple structure, low cost, is convenient for production and replacement, and can control the later maintenance cost. It can be understood that the elastic force of the spring can be flexibly selected according to the actual weight of the product 5, with high flexibility.

[0043] Please refer to the attached Figure 4 , the material discharging assembly 32 includes a limiting block 321 and a material discharging block 322. The limiting block 321 is connected to the elastic member 31, and the limiting block 321 can be in contact with the clamping block 11; one end of the limiting block 321 away from the elastic member 31 is connected to the material discharging block 322. Among them, the material discharging block 322 is in contact with the product 5. When the material discharging block 322 pushes the product 5 in the X direction for a certain distance, the clamping block 11 and the limiting block 321 will be in contact with each other, thereby restricting the movement of the material discharging block 322 in the X direction. Through this setting, on the one hand, it can prevent the material discharging block 322 from moving too much and causing the product 5 to fall. On the other hand, it is necessary to use the limiting block 321 to control the compressive force exerted by the elastic member 31, that is, after the product 5 is pushed out in the X direction for a certain distance, the elastic member 31 is still in a compressed state. This setting can ensure that the material discharging block 322 has a strong thrust, thereby ensuring a strong kinetic energy for pushing the product 5 and ensuring the smoothness of material discharging.

[0044] Please refer to the attached Figure 5 , the material supporting member 2 includes a material supporting block 21 and a fixing block 22. The fixing block 22 is arranged in the material placing cavity, and one end of the material supporting block 21 is connected to the fixing block 22, and the other end of the material supporting block 21 extends out of the material placing cavity. Among them, the material supporting block 21 is used to support the product 5 and provide a reference model for spinning the product 5. The fixing block 22 is used to support the material supporting block 21 to ensure the stability of the material supporting block 21. Through this setting, the stability during the spinning process can be correspondingly improved, thereby improving the spinning accuracy of the product 5 and ensuring the spinning quality.

[0045] Please refer to the attached Figure 6 - attached Figure 7 , the clamping member 1 further includes a pulling member 13 and a mounting seat 14. The pulling member 13 is drivingly connected to the clamping block 11 for movement, and the mounting seat 14 is sleeved on the clamping block 11. Among them, the pulling member 13 is driven to move by an existing rotary oil cylinder. When it is necessary to clamp the product 5, the pulling member 13 is driven to move in the Y direction, and then the clamping block 11 is driven to move in the Y direction; when it is necessary to loosen the product 5, the pulling member 13 is driven to move in the X direction, and then the clamping block 11 is driven to move in the X direction. With the cooperation between the mounting seat 14 and the clamping block 11, the clamping and loosening states can be achieved only when the clamping block 11 moves in the X or Y direction.

[0046] Specifically, one end of the clamping block 11 away from the pulling member 13 is provided with a tightening and loosening end 111, and the mounting seat 14 is provided with an adjusting end 141 corresponding to the tightening and loosening end 111. The first surface 1111 and the second surface 1112 are oppositely arranged on the tightening and loosening end 111. The first surface 1111 is oppositely arranged with the material supporting member 2 and is parallel to the material supporting member 2; the second surface 1112 is oppositely arranged with the adjusting end 141, and the second surface 1112 is gradually inclined towards the adjusting end 141 in the direction away from the pulling member 13 to form an inclined surface. The adjusting end 141 is provided with an adjusting surface 1411 corresponding to the second surface 1112, and the adjusting surface 1411 is connected to the second surface.

[0047] Through the structural design of the tightening and loosening end 111 in the clamping block 11 and the adjusting end 141 in the mounting seat 14, the operating principle of tightening and loosening the product 5 is as follows: when the clamping block 11 clamps the product 5, the pulling member 13 moves in the Y direction, thereby driving the clamping block 11 to move in the Y direction, so that the second surface 1112 of the tightening and loosening end 111 is in contact with the adjusting surface 1411 of the adjusting end 141. Since the second surface 1112 is gradually inclined towards the adjusting end 141 in the direction away from the pulling member 13 to form an inclined surface, when the clamping block 11 moves in the Y direction, the adjusting end 141 will exert a reaction force on the second surface 1112, causing the clamping block 11 to tighten towards the product 5, thereby clamping the product 5.

[0048] When the clamping block 11 loosens the product 5, the pulling member 13 moves in the X direction, thereby driving the clamping block 11 to move in the X direction, making the second surface 1112 of the tightening and loosening end 111 gradually tend to be parallel to the adjusting surface 1411 of the adjusting end 141. When the clamping block 11 moves in the X direction, the reaction force exerted by the adjusting end 141 on the second surface 1112 gradually decreases, causing the clamping block 11 to approach in the direction of the adjusting surface 1411, thereby loosening the product 5.

[0049] Through the above structural settings, the design is ingenious and simple. The product 5 can be tightened and loosened by horizontal movement, improving the convenience of tightening and loosening the product 5. The operation is convenient and easy, which is conducive to quickly switching the product 5 for spinning processing and improving the spinning efficiency. Moreover, this structural design is simple, with low manufacturing cost and strong practicability, facilitating wide use.

[0050] Embodiment 2:

[0051] The difference between this embodiment and Embodiment 1 is as follows. Please refer to Figures 8-9 , the fixture of this embodiment further includes a material ejecting member 4, and the material ejecting member 4 is arranged in parallel with the material supporting member 2.

[0052] Among them, the ejector member 4 is used to apply a force in the X direction to the product 5, thereby offsetting the reaction force of the unloading member 3 on the product 5. Generally, during the spinning process, the ejector member 4 only comes into contact with the product 5. Specifically, the movement of the ejector member 4 is to move in the X direction or in the Y direction, and its drive source can be realized by existing means.

[0053] Through the above setting of the ejector member 4, during the spinning operation of the product 5, the ejector member 4 can hold the product 5, thereby offsetting the reaction force of the unloading member 3 on the product 5, ensuring the stability of the product 5, and thus improving the quality of the spinning process. On the other hand, since the ejector member 4 offsets the reaction force of the unloading member 3, the clamping force of the clamping block 11 can be correspondingly reduced, avoiding the strong pressure of the clamping block 11 on the product 5, which may cause damage to the product 5, improving the protection force for the product 5, and also improving the durability of the clamping block 11, avoiding the problem of large wear of the clamping block 11 caused by strong pressure, and having a certain protection force for the clamping block 11.
