DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-6 A rubber tube forming mold comprises an upper mold shell 1 and a lower mold shell 2. The upper mold shell 1 and the lower mold shell 2 cooperate with each other to form a mold shell. The left end of the upper mold shell 1 is fixedly connected to a rear bracket 5 supporting the mold shell, and a supporting groove 502 is provided inside the rear bracket 5. The left end of the lower mold shell 2 is movably inserted into the inside of the supporting groove 502. The right end of the upper mold shell 1 is fixedly connected to a front bracket 6 supporting the mold shell, and a fixing groove 601 is provided inside the front bracket 6. The right end of the lower mold shell 2 is fixedly connected to a fixing block 202, and the fixing block 202 is movably engaged with the inside of the fixing groove 601. The inside of the mold shell is movably inserted with a central axis 3, and the left side of the lower mold shell 2 can be supported by the supporting groove 502, and the right side of the lower mold shell 2 can be supported by the fixing block 202. In this way, the lower mold shell 2 and the upper mold shell 1 can be separated and can form a complete mold shell at the same time, which is convenient for taking out the central axis 3 and the rubber tube.

[0023] The right side end of the mold shell is fixedly connected with a sealing cover 4 by bolts. The left and right ends of the central axis 3 respectively penetrate the mold shell and the sealing cover 4. The mold shell can be sealed by the sealing cover 4, which is convenient for disassembly.

[0024] A limiting ring 301 is fixedly connected to the outer end face of the left end of the central axis 3, and a limiting groove 501 cooperating with the limiting ring 301 is opened at the left end of the mold shell. The limiting ring 301 is movably inserted into the inside of the limiting groove 501. The central axis 3 can be positioned by the limiting ring 301 and the limiting groove 501, and the position of the central axis 3 inserted into the mold shell can be fixed.

[0025] An abutment ring 302 is fixedly connected to the outer end face of the right end of the central axis 3, and an abutment groove 401 that cooperates with the abutment ring 302 is opened inside the sealing cover 4. The abutment ring 302 is movably inserted into the inside of the abutment groove 401. The sealing cover 4 can be positioned by the abutment ring 302 and the abutment groove 401, which facilitates the sealing cover 4 to seal the mold shell.

[0026] A through hole 303 penetrating the central shaft 3 is provided inside the central shaft 3 . Cooling water can be injected through the through hole 303 to cool the rubber tube, thereby increasing the molding speed of the rubber tube.

[0027] A sealing ring 201 is fixedly connected to the left end of the lower mold shell 2, and a sealing groove 503 that cooperates with the sealing ring 201 is opened inside the rear bracket 5. The sealing ring 201 is movably inserted into the sealing groove 503. Through the cooperation between the sealing ring 201 and the sealing groove 503, the lower mold shell 2 is conveniently positioned, and at the same time, the integrity of the upper mold shell 1 and the lower mold shell 2 is improved to prevent the rubber tube raw material from leaking out.

[0028] A handle 203 is fixedly connected to the outer end surface of the fixing block 202 , and the lower mold shell 2 can be easily pulled out by providing the handle 203 .

[0029] Working method: When working, the raw material is injected into the mold shell through the feed port, and the rubber tube is cooled and formed inside the mold shell. During the rubber tube forming process, cooling water is injected through the through hole 303 of the central axis 3 to increase the cooling and forming speed of the rubber tube. After the rubber tube is cooled and formed, the sealing cover 4 can be removed by turning the bolt. At this time, pulling the handle 203 can separate the lower mold shell 2 from the upper mold shell 1, which greatly facilitates the removal of the central axis 3 and the rubber tube. At the same time, there is no need to rotate the rubber tube inside the mold shell, which prevents the rubber tube from twisting and deformation, improves the yield rate of the rubber tube, and has a good use effect.
