In order to solve the problems of the technologies described above, the utility model alloy liquid cast tubes mainly comprises existing unidirectional woven hose; The liquid outlet that it is characterized by at unidirectional woven hose is with a fluid switch, and this fluid switch is made up of overcoat and central plug; Overcoat is a hollow pipe, and central plug is positioned at overcoat, and its top cooperates with the overcoat underclearance, and the extended overcoat outlet in bottom; Be connected to simultaneously a return duct on unidirectional woven hose, connection place of return duct on unidirectional woven hose tube wall is near the overcoat outlet.
Central plug in the fluid switch on the utility model alloy liquid cast tubes is to rely on deadweight to sink to blocking the overcoat outlet; Certainly the gap fiting mode of the top of central plug and overcoat bottom is various, central plug shaped upper part in the fluid switch and overcoat bottom are complementary near the cavity shape in exit: the overcoat bottom is coniform, the central plug shaped upper part for overcoat lower cone shape inner chamber be complementary coniform; When both mate, can be close between the contact-making surface, thereby both closed overcoat switch has further guaranteed the sealing of fluid switch again.When relative overcoat bottom, central plug top moved upward, both untied cooperation, produce the gap between contact-making surface, thereby made the overcoat outlet open-minded.
During work, this alloy liquid cast tubes inlet connects electronic delivery pump leakage fluid dram, and the fluid switch is aimed at the die casting mouth, and an end of return duct places casting furnace.And cast tubes self can rely on other mechanisms to finish lifting of integral body and descend, and does not lay down a definition at this.The fluid switch stretches into mould along with the decline of cast tubes earlier, and the central plug bottom stops after touching die bottom plate, and overcoat continues to descend, thereby because of relative motion, untie and the cooperating of overcoat bottom on central plug top, and overcoat exports just by open-minded, alloy liquid is flowed out realize casting.In this process, when the overcoat outlet was bumped to die bottom plate, it is maximum that the open degree of fluid switch reaches.When alloy liquid level in the mould arrives predetermined altitude and need stop to cast, lift cast tubes, the fluid switch seals rapidly, and delivery pump was constantly squeezed into return duct to alloy liquid in the pipe and was flowed back to casting furnace this moment.
Return duct of the present utility model and unidirectional woven hose be communicated with the height that length between place and the outlet of fluid switch overcoat should equal mold cavity in the mould at least, purpose is when preventing that the fluid switch from entering the die casting chamber, the backflow tube wall of above-mentioned connection place and die casting mouth extension are touched and are hindered the outlet of overcoat below and contact die bottom plate, thereby cause the problem that the fluid switch can not complete opening.
Can be fastenedly connected by tie-beam between return duct sidewall of the present utility model and the unidirectional woven hose sidewall, two pipes can be supported mutually, purpose is to reduce return duct to be communicated with the place with unidirectional woven hose, because of the shearing force that the return duct deadweight produces, prevents the cracking of connection place tube wall.Also make simultaneously the more compact structure of cast tubes integral body.
The utility model is a kind of alloy liquid cast tubes simple in structure, easy to use, closes rapidly when the fluid switch on its liquid outlet can reach predetermined altitude in alloy liquid injects mould, and unnecessary alloy liquid can flow back to casting furnace by return duct in the pipe simultaneously.Compare with traditional cast tubes that is provided with the transition bag, because the structural design of this cast tubes is more reasonable, so interior liquid level of the more effective control mould of energy and the obstruction that prevents self when using it to cast, and removed loaded down with trivial details manual operation from, alleviate workman's burden, improved production efficiency.
