The notches 16 penetrate the side walls of the inner mold 1 and the support plate 7. Connecting pipes 8 are fixedly provided on the side walls of the support plate 7 near the notches 16. Two through-holes 13 are symmetrically fixedly provided on the side walls of the support plate 7 near the two connecting pipes 8. Cooling pipes 17 are evenly arranged inside the notches 16. Both ends of the cooling pipes 17 are connected to the connecting pipes 8 in sequence, and the middle of the cooling pipes 17 penetrates the two through-holes 13 in sequence. The cooling pipes 17 are made of rubber and are evenly arranged inside the cooling pipes 17.

[0023] The top of the fixed platform 9 is fixedly connected to the cylinder 2 10 by bolts, and the output end of the cylinder 2 10 is fixedly connected to the connecting plate 11 by a coupling. The connecting plate 11 is rectangular, and two top supporting assemblies 12 are symmetrically fixed at the top position of the connecting plate 11. The two top supporting assemblies 12 are both T-shaped, and the external dimensions of the top supporting assemblies 12 are compatible with the internal dimensions of the slot 15. Starting the cylinder 2 10 can drive the connecting plate 11 and the top supporting assembly 12 to move horizontally, thereby pushing the barrel body out of the outer surface of the inner mold 1, thereby improving the efficiency of barrel body peeling.

[0024] The two connecting pipes 8 are symmetrically distributed, and the connecting pipes 8 are both connected to the second groove 16. The other end of the connecting pipe 8 is provided with a threaded groove 18 for threaded connection of the water pipe.

[0025] Working principle: When using this type of uniform weight internally reinforced trapezoidal barrel injection mold, the operator first connects the external power supply, the support plate 7 is fixed to the side walls of the four support frames 3 by bolts, and the support plate 7 is supported by the fixed platform 9 and the support frame 3. The support plate 7 and the inner mold 1 are fixedly connected to form an integrated structure, and the outer mold 2 is pushed to move by starting the cylinder 1 5, so that the outer mold 2 is sleeved on the outer surface of the inner mold 1. The outer size of the inner mold 1 is adapted to the inner size of the outer mold 2. The top of the outer mold 2 is plugged with an injection port 14 for filling with plastic glue, thereby completing the injection molding. When the injection molding is completed, it is necessary to wait for the plastic glue to cool down. The groove 2 16 surrounds the groove The opening 15 is opened inside the inner mold 1 to facilitate the installation of the cooling pipe 17. The cooling pipe 17 is made of rubber and is evenly arranged inside the cooling pipe 17 to transport cooling water to avoid direct contact between the cooling water and the inner mold 1, thereby increasing the rate at which the temperature of the inner mold 1 decreases, improving the efficiency of curing, and thus improving the production efficiency of the trapezoidal barrel. When the injection molding glue is cured, the cylinder 15 is started again to move the outer mold 2 in the opposite direction, thereby separating the outer mold 2 and the inner mold 1 and leaking out the molded barrel body. Then starting the cylinder 2 10 can drive the connecting plate 11 and the top support assembly 12 to move horizontally, thereby pushing the barrel body out of the outer surface of the inner mold 1, thereby improving the efficiency of barrel body peeling.
