[0023] Through the design of the through hole 9 and the exhaust hole 10 of the upper mold 6 and the adjustable sealing block 12 structure, the gas in the mold can be effectively discharged in time, the void can be avoided, the mechanical properties of the wheel hub can be greatly improved, the strict requirements of high strength and high reliability during automobile driving can be met, meanwhile, in the protection of the exhaust hole 10, the protective block 18 and the spring one 20 structure of the system can effectively prevent foreign matters from entering the exhaust hole 10 to cause blockage, ensure the stable operation of the exhaust system, avoid various quality problems caused by poor exhaust, further improve the production efficiency, and bring better benefits to enterprises.

[0024] As Figure 3As shown, the through hole 9 and the exhaust hole 10 are in communication with each other, and the sealing block 12 is in sliding connection with the through hole 9, so that the gas in the mold can smoothly enter the exhaust hole 10 through the through hole 9, and the exhaust amount can be controlled by adjusting the position of the sealing block 12, ensuring that the gas is discharged in time during injection molding, avoiding affecting the forming quality of the hub.

[0025] As shown in Figure 1 and Figure 3 The guide column 13 is in sliding connection with the upper mold 6, and the connecting plate 5 is in sliding connection with the stand column 2, the guide column 13 ensures the stable movement of the sealing block 12 and accurately adjusts the exhaust, and the connecting plate 5 and the stand column 2 are in sliding connection, which makes the opening and closing of the upper mold 6 smooth, which is beneficial to stable injection molding and exhaust.

[0026] As shown in Figure 5 The protective block 18 is in sliding connection with the upper mold 6, one end of the spring 20 is fixedly connected with the fixed plate 16, and the other end of the spring 20 is fixedly connected with the protective block 18, so that the protective block 18 can block foreign matter from entering the exhaust hole 10, and the spring 20 realizes the automatic reset function of the protective block 18.

[0027] As shown in Figure 1 The top of the connecting plate 5 is symmetrically fixedly installed with the connecting rod 21, the top end of the connecting rod 21 is fixedly installed with the fixed block 22, and the outer wall of the connecting rod 21 is sleeved with the spring 23.

[0028] As shown in Figure 1 The connecting rod 21 is in sliding connection with the top plate 3, one end of the spring 23 is fixedly connected with the fixed block 22, and the other end of the spring 23 is fixedly connected with the top plate 3, which further ensures the effective play of the buffering function of the spring 23 and guarantees the stability of the upper mold 6 during the rising and falling process, providing protection for high-quality production of the hub.

[0029] The working principle of the embodiment is as follows: in use, first, the hydraulic cylinder 4 is started, the output end of the hydraulic cylinder 4 pushes the connecting plate 5 to slide down along the stand 2, drives the upper mold 6 to close with the lower mold 7, at this time, the injection molding pipe 8 is used to inject the injection molding material into the lower mold 7. In the injection molding process, the original air in the mold and the gas volatilized from the injection molding material begin to accumulate, at this time, the knob 15 can be rotated to drive the threaded rod 11 to rotate in the inside of the upper mold 6. Since the threaded rod 11 is in threaded connection with one side of the inside of the upper mold 6 and the guide column 13 is in sliding connection with one side of the inside of the upper mold 6, when the threaded rod 11 rotates, the guide column 13 will stably slide along the sliding track in the inside of the upper mold 6. The one end of the guide column 13 is fixed on the sealing block 12, which ensures that the sealing block 12 cannot rotate by itself when the threaded rod 11 rotates, but can only move smoothly along the axial direction of the threaded rod 11. When the threaded rod 11 reversely rotates, the sealing block 12 moves away from the exhaust hole 10, thereby increasing the air passage area between the through hole 9 and the exhaust hole 10, and a large amount of accumulated gas can be quickly discharged. When the threaded rod 11 rotates forward, the sealing block 12 moves towards the exhaust hole 10, and the air passage area decreases, so that the gas discharge speed can be controlled when the gas pressure is low or in the early stage of injection molding, and the injection molding material is prevented from leaking from the exhaust hole 10. Before exhaust, the pull plate 19 can be pulled upwards to drive the sliding rod 17 to slide upwards in the inside of the fixed plate 16. In the process of sliding upwards, the sliding rod 17 drives the protective block 18 to move upwards and compresses the spring I 20 to the place where the fixed plate 16 is located. After being compressed to a certain extent, the protective block 18 will no longer block the exhaust hole 10. When the pull plate 19 is released, the rebounding force of the spring I 20 will push the protective block 18 back to the original position, thereby blocking the exhaust hole 10, and effectively preventing foreign matters from entering the exhaust hole 10 and causing blockage. In the injection molding process, the connecting plate 5 top symmetrically installed connecting rod 21 will slide downwards in the top plate 3, and the spring II 23 sheathed on the outer wall of the connecting rod 21 is compressed at this time. The existence of the spring II 23 can provide a certain buffer for the descending process of the connecting plate 5 and the upper mold 6, so as to avoid damage to the upper mold 6 and the lower mold 7 due to excessive speed or excessive impact force, and to ensure that the upper mold 6 and the lower mold 7 can be stably and accurately closed, thereby laying a foundation for the smooth development of the subsequent injection molding process.

[0030] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments shall fall within the protection scope of the technical scheme of the present application.
