[0026] Among them, the moving component 2 includes a core mold body 21, one end of the core mold body 21 is fixedly connected to a connecting plate 22, the side of the connecting plate 22 away from the core mold body 21 is fixedly connected to a first U-shaped ear 23, the side of the first U-shaped ear 23 away from the connecting plate 22 is provided with a first ear 24, the side of the first ear 24 away from the first U-shaped ear 23 is fixedly connected to a load-bearing column 25, a plurality of connecting holes 26 are opened through the bottom of the surface of the load-bearing column 25, the bottom of the load-bearing column 25 is fixedly connected to a plurality of moving wheels 27, and the bottom of the moving wheels 27 are each provided with a sliding bar 28.

[0027] Among them, the pushing component 3 includes a connecting frame 31, which is fixedly connected to the bottom of both sides of the forming component 11, and a second telescopic cylinder 32 is provided on the top of the connecting frame 31. The telescopic end of the second telescopic cylinder 32 is fixedly connected to a second lifting ear 33, and a second U-shaped lifting ear 34 is provided on the side of the second lifting ear 33 away from the second telescopic cylinder 32.

[0028] Among them, the core body 21 penetrates the core moving groove 117, the connecting plate 22 is arranged on the side of the sliding plate 115 away from the lower mold 111, and the top of the upper mold 120 is provided with a feed port; the silicone curved tube formed on the outer surface of the core body 21 is pushed through the core moving groove 117 to achieve the demolding effect through the resistance of the sliding plate 115.

[0029] Among them, the core body 21 is arranged in the lower molding groove 112 and the upper molding groove 122, and one end of the sliding bar 28 is fixedly connected to the lower mold 111; in later use, it can ensure that when the load-bearing column 25 slides, the sliding bar 28 can be stable and will not cause the load-bearing column 25 to derail.

[0031] Working principle of this utility model:

[0032] During later use, liquid silicone is first poured into the material inlet opened at the top of the upper mold 120. After molding, the first telescopic rod 119 is telescoped by activating the first telescopic cylinder 114. The upper mold 120 is lifted by the telescopic movement of the first telescopic rod 119. The surface quality of the formed silicone elbow can be observed. After the inspection is qualified, the second telescopic cylinder 32 is activated to push the push plate 35. The push of the push plate 35 enables the load-bearing column 25 to slide along the sliding bar 28. The sliding of the load-bearing column 25 drives the mold core body 21 to be pulled out. During the pulling out process, the silicone elbow is always in a sliding state. The plate 115 is close to the side of the lower mold 111. When the load-bearing column 25 drives the core body 21 to slide to the maximum distance, the core body 21 is at the intersection of the core moving groove 117 and the lower molding groove 112, and the molded silicone elbow can be completely removed. After the load-bearing column 25 is retracted by starting the second telescopic cylinder 32, the core body 21 can be completely located in the lower molding groove 112 and the upper molding groove 122 again. After the first telescopic cylinder 114 lowers the upper mold 120, the molding process can be carried out again, which solves the problem that the existing silicone elbow molding mold is difficult to remove after the molding is completed.
