Description

Technical Field

[0001] The utility model relates to the technical field of casting systems, in particular to a grooved reducing pipe casting system. Background Art

[0002] The traditional flange connection and welding methods used in pipeline connection have the defects of complex installation, low efficiency, welding quality, safety, and high environmental pollution risks. The development and application of grooved pipe fittings make complex pipeline connection projects simple, fast, efficient, reliable, safe, and environmentally friendly, becoming the first choice technology for liquid and gas pipeline connection. This technology has a wide range of applications in pipeline connection in the fields of fire protection, water supply and drainage, electricity, petroleum, chemical industry, subway, airport, tunnel, etc.

[0003] During the production process of pipe fittings, the mold on it needs to be poured by a pouring machine. After the pouring is completed, the condensed pipe fittings need to be demoulded. The traditional demoulding method is to manually use tools to embed it between the pipe fitting and the injection mold, and then shake and pull to complete the demoulding of the pipe fitting. However, this method will cause scratches and wear on the surface of the pipe fitting, which has a great impact on the quality of the finished product of the pipe fitting.

[0004] The prior art discloses a patent with a publication number of CN216758136U, which includes an installation box, a mounting frame fixedly connected to the top of the installation box, a hydraulic cylinder penetrating and fixedly connected to the side wall of the installation frame, a sealing plate fixedly connected to the piston end of the hydraulic cylinder, a mold fixedly connected to the top of the installation box, two vertical rotating rods penetrating and rotatably connected to the upper surface of the installation box, two horizontal rotating rods penetrating and rotatably connected to the side wall of the installation frame, and the sealing plate and the horizontal rotating rod are connected through a transmission assembly. When the injection molding is completed, the transmission assembly drives the horizontal rotating rod to rotate, the horizontal rotating rod drives the vertical rotating rod to rotate through the cone wheel assembly, and the vertical rotating rod drives the bottom plate to move upward through the reciprocating mechanism. The bottom plate pushes the pipe fittings out of the mold during the upward movement, and there is no need to manually demold the pipe fittings, which effectively avoids scratches and wear on the pipe fittings during the demolding process.

[0005] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0006] First, during the casting process, the existing different-diameter grooved pipe fittings cannot ensure the cooling uniformity of the different-diameter grooved pipe fittings, resulting in the formation of heat knots, holes, shrinkage and other problems that affect the appearance and performance quality of the product.

[0007] Second, after the casting of the existing different-diameter grooved pipe fittings is completed, it is limited by the demoulding structure and cannot be quickly demoulded, which in turn affects the demoulding efficiency.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
