[0007] A further improvement is that a groove is provided inside the hinge seat, the top end of the threaded rod passes through the inside of the groove, and the diameter of the bottom end of the fixing cap is greater than the width of the groove.

[0008] A further improvement is that the outer walls of the support ring and the end cover are fitted and connected to the inner walls of the upper die base and the lower die base, and the front and back sides of the upper die base and the lower die base are symmetrically provided with pressing edges, and the inner diameter of the pressing edges is smaller than the outer diameter of the support ring and the end cover.

[0009] A further improvement is that a layer of mold release agent is sprayed on the upper mold base, the lower mold base and the support ring, and connecting rings are symmetrically fixedly connected to the two ends of the top of the upper mold base, and the upper mold base is fixedly connected to the external lifting device through the connecting rings.

[0010] A further improvement is that a group of fixing rods are symmetrically fixedly connected to both ends of the lower die base, the fixing rods are fixedly connected to the lower die base through locking rods, and a reinforcing rod and a bottom rod are fixedly connected to the inner side of a group of fixing rods.

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] according to Figure 1 ,2 As shown in Figure 3, this embodiment proposes a rubber valve core joint combined vulcanization mold, including an upper mold base 1 and a lower mold base 2, the bottom of the upper mold base 1 is provided with a lower mold base 2, and the upper mold base 1 and the lower mold base 2 are provided with a support ring 17 inside, one end of the support ring 17 is clamped with an end cover 5, and the outer side of the end cover 5 is fixedly connected with a handle 6, and a quick connection mechanism is provided between the upper mold base 1 and the lower mold base 2. When the vulcanization mold is in use, the rubber skin is attached to the outer side of the support ring 17, and then the end cover 5 is clamped on one side of the support ring 17 through the handle 6, and the support ring 17 together with the end cover 5 is placed in the interior of the lower mold base 2, and the upper mold base 1 is covered on the top of the lower mold base 2, and then the upper mold base 1 and the lower mold base 2 are fixed together through the quick connection mechanism, so that the rubber is fixed inside the mold, and finally the mold is pushed into the vulcanization equipment for vulcanization, and the rubber is removed from the mold after the vulcanization is completed.

[0019] The quick connection mechanism includes a fixed seat 3, an articulated seat 4, an articulated block 8, a threaded rod 9 and a fixing cap 10. The fixed seats 3 are symmetrically provided at both ends of the lower mold base 2, and the articulated seats 4 are symmetrically provided at both ends of the upper mold base 1. The interior of the fixed seat 3 is hinged with an articulated block 8, one end of the articulated block 8 is fixedly connected to a threaded rod 9, and the top end of the threaded rod 9 is threadedly connected to a fixing cap 10.

[0020] A groove 16 is provided inside the hinge seat 4 , and the top end of the threaded rod 9 passes through the inside of the groove 16 . The diameter of the bottom end of the fixing cap 10 is greater than the width of the groove 16 .

[0021] After the upper die base 1 is covered on the top of the lower die base 2, the threaded rod 9 is rotated upward so that the threaded rod 9 passes through the inside of the groove 16, and the fixing cap 10 is screwed in the direction of the hinge seat 4. The hinge seat 4 is clamped by the fixing cap 10. At this time, the fixing seat 3 and the hinge seat 4 are locked with each other to fix the upper die base 1 and the lower die base 2 together. When it is necessary to separate the upper die base 1 from the lower die base 2, the fixing cap 10 is screwed to separate from the hinge seat 4, and the threaded rod 9 is rotated downward to move the fixing cap 10 out of the range of the hinge seat 4. The fixing cap 10 no longer limits the hinge seat 4. At this time, the upper die base 1 can be removed from the top of the lower die base 2.

[0022] The outer walls of the support ring 17 and the end cover 5 are fitted and connected with the inner walls of the upper mold base 1 and the lower mold base 2. The front and back sides of the upper mold base 1 and the lower mold base 2 are symmetrically provided with pressure edges 15. The inner diameter of the pressure edge 15 is smaller than the outer diameter of the support ring 17 and the end cover 5. When the support ring 17 and the end cover 5 enter the interior of the upper mold base 1 and the lower mold base 2, the pressure edge 15 fits with one side of the support ring 17 and the end cover 5 to limit the support ring 17 and the end cover 5 to prevent the support ring 17 and the end cover 5 from falling from the mold during the movement of the mold. The end cover 5 can be taken out of the mold by holding the handle 6.

[0023] A layer of mold release agent is sprayed on the upper mold base 1, the lower mold base 2 and the support ring 17. The two ends of the top of the upper mold base 1 are symmetrically fixedly connected with connecting rings 7. The upper mold base 1 is fixedly connected to the external lifting device through the connecting ring 7. The mold release agent is evenly applied to the inside of the upper mold base 1 and the lower mold base 2 to facilitate the demoulding of the rubber from the inside of the upper mold base 1 and the lower mold base 2. The lifting device is fixed together with the connecting ring 7, and the lifting device can drive the upper mold base 1 to move upward to separate the upper mold base 1 from the lower mold base 2.

[0024] A group of fixing rods 11 are symmetrically fixedly connected to both ends of the lower die base 2, and the fixing rods 11 are fixedly connected to the lower die base 2 through locking rods 12. A reinforcing rod 13 and a bottom rod 14 are fixedly connected to the inner side of a group of fixing rods 11. The fixing rods 11, the reinforcing rods 13 and the bottom rod 14 are combined into a fixing frame, and the fixing frame is fixedly connected to one side of the lower die base 2. The fixing frame is fixed together with the bottom of the lower die base 2 through the locking rod 12, so that the fixing frame and the lower die base 2 play a supporting role.

[0025] The support ring 17 and the end cover 5 are combined into an I-shaped structure. The outer diameters of the support ring 17 and the end cover 5 are equal, and the outer side of the support ring 17 is attached with rubber skin.

[0026] The combined vulcanizing mold, after the upper mold base 1 is covered on the top of the lower mold base 2, the threaded rod 9 is rotated upward so that the threaded rod 9 passes through the inside of the groove 16, and the fixing cap 10 is screwed in the direction of the hinge seat 4, and the hinge seat 4 is clamped by the fixing cap 10. At this time, the fixing seat 3 and the hinge seat 4 are locked with each other to fix the upper mold base 1 and the lower mold base 2 together. When it is necessary to separate the upper mold base 1 from the lower mold base 2, the fixing cap 10 is screwed to separate the hinge seat 4, and the threaded rod 9 is rotated downward to move the fixing cap 10 out of the range of the hinge seat 4. The fixing cap 10 no longer limits the hinge seat 4. At this time, the upper mold base 1 can be removed from the top of the lower mold base 2 to solve the problem that the upper and lower molds of the combined mold in the prior art are too poorly fitted, which makes the press-vulcanized object easy to deform, thereby affecting the quality of the rubber valve core.
