[0002] Steel wire pipe is a kind of industrial product of pipe material. Steel wire pipe can be divided into: high-pressure steel wire pipe, low-pressure steel wire pipe, steel wire skeleton pipe, transparent steel wire pipe. Among them, high-pressure steel wire pipe can be divided into: steel wire braided hose, steel wire winding hose; low-pressure steel wire pipe and steel wire skeleton pipe can be collectively referred to as low-pressure hose; transparent steel wire pipe mainly refers to PVC plastic hose.
[0003] Transparent steel wire hose is also known as PVC steel wire spiral reinforced hose. For example, the PVC steel wire spiral reinforced hose produced by the PVC hose industry is called "steel wire hose" within the industry. PVC steel wire spiral reinforced hose is a PVC hose reinforced with steel wire. The product is made of PVC plastic as the main body and embedded with spiral steel wire as a reinforcement layer. Therefore, the product is both rigid and flexible, with sufficient mechanical properties and rigidity, as well as excellent flexibility.
[0004] During the casting and shaping process, the existing steel wire pipe outer layer mold is prone to expand and deform according to the principle of thermal expansion and contraction, which causes air to enter the mold and produce gas bubbles in the casting liquid, affecting the quality requirements for the casting and molding of the outer layer PVC pipe of the steel wire mesh pipe.

[0007] A shaping mold, which is screwed to the outside of the casting mold, and is used to shape the position where the Jinxiong steel wire needs to be wound during the casting process;
[0008] A docking frame, arranged at one end of the casting mold, for limiting and fixing the end of the casting mold;
[0009] A sealing mechanism, screwed between the casting mold and the docking frame, for sealing the inside of the casting mold;
[0010] The barrier frame is screwed between the casting mold and the sealing mechanism to assist the sealing mechanism in sealing.
[0011] Preferably, the molding die comprises a fixing half ring and four sets of fixing bolts, the fixing bolts are screwed to a welding frame on the casting die, and the molding half ring is welded and mounted on the welding frame.
[0012] Preferably, the casting mold includes a casting channel opened inside the casting mold and two groups of mounting grooves opened in a circle outside the casting mold.
[0013] Preferably, the molding semi-ring is provided with a molding arc surface, and the molding semi-ring and the mounting groove are fixed by snap connection.
[0014] Preferably, the sealing mechanism comprises a sealing ring, four groups of reaction force surfaces arranged in a circle outside the sealing ring, and a force surface arranged between the sealing ring and the docking frame.
[0015] Preferably, an extrusion surface is provided on the docking frame, and the extrusion surface and the force-bearing surface are force-coordinated with each other.
[0016] Preferably, the barrier frame includes a circle of casting grooves opened on the barrier frame, and clamping bolts screwed between the barrier frame and the sealing mechanism.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] When the utility model is pouring inside the casting mold, the heat generated by the liquid will cause the entire mold to expand and contract, thereby causing air to enter at the interface position. The barrier frame, the sealing mechanism and the docking frame cooperate with each other, and the heat generated inside the casting trough diffuses outward to cause the barrier frame to expand and squeeze the sealing ring. The force-bearing surface on the sealing ring and the docking frame that is not in contact with the heat are squeezed against each other, so that the extruded surface squeezes the force-bearing surface. At this time, the force is transmitted to the counter-force surface on the sealing ring. At the same time, the counter-force surface is clamped and fixed by the clamping bolts, thereby ensuring the sealing effect of the mold during use and avoiding casting of PVC pipes with bubbles and substandard quality.
