The utility model discloses an injection mold convenient to exhaust, which relates to the technical field of injection molds and comprises a lower mold, an upper mold is attached to the top of the lower mold, an exhaust hole is fixedly arranged in the upper mold, and a steel needle is slidably arranged in the exhaust hole through a lifting component. And a heating assembly is arranged in the upper mold. Through the installation of the heating assembly, when the exhaust hole is blocked by a rubber foreign matter, the spring heating ring is heated through an external controller, and the heating temperature of the spring heating ring is controlled, so that the circular heating cavity and the exhaust hole are directly heated, the rubber foreign matter is softened and expanded, and then a steel needle is inserted into the exhaust hole to eject the rubber foreign matter out; the heating process is fast, the temperature can be precisely controlled, and the problems that in the prior art, when the exhaust hole of the injection mold is dredged through a heating method, the heating time of the mold is long, and the mold is burnt out due to the fact that the temperature is not well controlled are solved.

This utility model discloses a silt removal device for subsea pipeline construction, including a protective shell, a first gear, and a second gear. A toothed plate is provided on one side of the inner wall of the protective shell, and the first gear and the second gear are meshed together. This silt removal device for subsea pipeline construction, through the arrangement of the protective shell, first gear, second gear, toothed plate, drill bit, support rod, and stirring blade, allows the user to place the device into the subsea pipeline and move it downwards. Rotating the first gear drives the drill bit to disperse accumulated silt. The second gear meshes with both the first gear and the toothed plate, so that when the first gear rotates, the second gear rotates around the first gear as an axis, and simultaneously rotates itself. This causes the stirring blade to rotate around the first gear, preventing silt from being pushed into the protective shell, thus achieving the effect of simultaneously removing silt from the subsea pipeline and its internal components.
