Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Referring to fig. 1, a cable mold for synchronously completing vulcanization and injection molding comprises a vulcanization mold 1 and an injection mold 2, wherein a vulcanization molding cavity 3 for placing silicone rubber and a cable is arranged in the vulcanization mold 1, and the vulcanization molding cavity 3 is formed by closing an upper mold and a lower mold of the vulcanization mold 1. An injection molding cavity 4 used for injecting epoxy resin to a transition section between a bare wire and a joint is arranged in the injection mold 2, the injection molding cavity 4 is formed by closing an upper mold and a lower mold of the injection mold 2, and an injection molding hole 5 communicated with the injection molding cavity 4 is arranged on the upper mold of the injection mold 2. When the vulcanization mold 1 and the injection mold 2 are spliced together, the vulcanization molding cavity 3 and the injection molding cavity 4 are communicated with each other, and the center of the vulcanization molding cavity 3 and the center of the injection molding cavity 4 are positioned on the same straight line.
As shown in fig. 2, when the bare wire is wrapped with silicone rubber, the upper die of the vulcanizing die 1 needs to be buckled to the lower die of the vulcanizing die 1, the upper die and the lower die extrude with each other, and in the extruding process, redundant silicone rubber strips in the vulcanizing die cavity 3 are extruded and overflowed. Therefore, a first overflow channel 6 is arranged in the vulcanization mold 1, the first overflow channel 6 is formed by matching an upper mold and a lower mold of the vulcanization mold 1, and the first overflow channel 6 is symmetrically arranged about the axis of the vulcanization molding cavity 3 and is close to the vulcanization molding cavity 3.
As shown in fig. 2, in order to further accommodate the overflowing silicone rubber strip, a second overflow channel 7 is further arranged in the vulcanization mold 1, the second overflow channel 7 is located on one side of the first overflow channel 6, which is far away from the vulcanization molding cavity 3, a plurality of overflow holes 8 are arranged between the first overflow channel 6 and the second overflow channel 7, and the overflow holes 8 are arranged along the length direction of the first overflow channel 6. One end of the overflow hole 8 is communicated with the first overflow channel 6, and the other end of the overflow hole 8 is communicated with the second overflow channel 7.
As shown in fig. 2, a positioning post 21 for positioning the cable connector is disposed on the lower mold of the injection mold 2.
