Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to a hose with a connection structure. Background Art

[0002] The pipeline is a connecting pipe on the large stamping die. Air is inflated into the die through the pipeline to keep the pressure inside the die at the set value.

[0003] In related technologies, such as Figure 1 The large injection mold includes an injection molding machine body 4, a connecting pipe 5 and a metal pipe 6. There are two metal pipes 6. In order to keep the pressure inside the injection molding machine body 4 at a set value, one end of the connecting pipe 5 is connected to the injection molding machine body 4, and the other end of the connecting pipe 5 is connected to other equipment. One end of the metal pipe 6 is welded to the connecting pipe 5, and the other end of the metal pipe 6 is fixedly connected to the injection molding machine body 4. One of the metal pipes 6 can be punched from the outside to the inside of the injection molding machine body 4, and the other metal pipe 6 is exhausted to the outside of the injection molding machine body 4, so as to keep the pressure inside the injection molding machine body 4 at a set value.

[0004] Regarding the above-mentioned related technologies, the metal tube is usually welded to the connecting tube. Since the injection molding machine body often performs stamping actions, the metal tube needs to be inflated and exhausted while moving, which makes it easier for cracks to appear at the welding point and causes pressure relief. There is still room for improvement. Utility Model Content

[0005] In order to reduce the welding of metal tubes on the injection molding machine body, since the injection molding machine body often performs stamping actions, the metal tubes need to be inflated and exhausted while moving, which makes it easier for cracks to appear at the welding points and leakage occurs. The present application provides a hose with a connecting structure.

[0006] The present application provides a hose with a connection structure, which adopts the following technical solution:

[0007] A hose with a connecting structure comprises a hose for ventilation, a connecting flange fixedly connected to a stamping die, and a connecting assembly, wherein the hose is sleeved and fixedly connected to the connecting assembly, a ventilation pipe is fixedly connected to the connecting flange, and one end of the connecting assembly away from the hose is fixedly connected to the ventilation pipe.

[0008] By adopting the above technical solution and setting of the hose, the collision between the hose and the ventilation pipe is reduced when the mold is stamping, the softness of the connection between the hose and the ventilation pipe is increased, and the possibility of breakage and leakage is reduced.

[0009] Optionally, the connecting assembly includes a connecting pipe, the connecting pipe is rigidly connected to the hose, and one end of the connecting pipe away from the hose and one end of the ventilation pipe away from the connecting flange are integrally arranged.

[0010] By adopting the above technical solution, the connecting pipe and the ventilation pipe are arranged in one piece, so as to avoid rupture between the connecting pipe and the ventilation pipe during vibration, and increase the stability of the connection between the hose and the ventilation pipe.

[0011] Optionally, the connecting assembly also includes a fixing cylinder, a fixing ring is fixedly connected in the fixing cylinder, the fixing ring is located between the connecting pipe and the ventilation pipe, a cavity is defined in the fixing ring, one end of the fixing ring is slidably connected to a first limit block, the first limit block is located in the cavity and extends outside the fixing ring, a first clamping groove is defined at one end of the connecting pipe away from the hose, the first limit block is clamped in the first clamping groove, the other end of the fixing ring is slidably connected to a second limit block, the second limit block is located in the cavity and extends outside the fixing ring, a second clamping groove is defined at one end of the ventilation pipe away from the connecting flange, the second limit block is clamped in the second clamping groove, a compression spring is defined in the fixing ring, one end of the compression spring is embedded in the cavity and abuts on the first limit block, and the other end of the compression spring abuts on the second limit block, and a toggle hole is defined on the outer circumferential side wall of the connecting pipe, the toggle hole and the first clamping groove are communicated with each other.

[0012] By adopting the above technical solution, part of the first limit block abuts against the side wall of the first slot, and part of the second limit block abuts against the side wall of the second slot, thereby preventing the connecting pipe and the ventilation pipe from detaching from the fixing ring. On the other hand, when the staff needs maintenance, when a small wooden stick is used to push the first limit block from the toggle hole, the fixing ring can be removed, thereby allowing the connecting pipe and the ventilation pipe to be removed.

[0013] Optionally, a first guide block is fixedly connected to a side of the first limit block close to the second limit block, and a second guide block is fixedly connected to a side of the second limit block close to the first limit block, one end of the compression spring is sleeved on the first guide block, and the other end of the compression spring is sleeved on the second guide block.

[0022] By adopting the above technical solution, the setting of the first placement groove, the second placement groove and the rubber plug allows part of the fixing tube to be embedded in the first placement groove and the second placement groove, thereby preventing the fixing tube from moving in the first placement groove and the second placement groove. On the other hand, when the rubber plug is removed, the fixing ring can move in the first placement groove and the second placement groove, thereby enabling the connecting pipe and the ventilation pipe to be disassembled.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:
