In this patent, the screw, bearing, shock-absorbing spring and guide block can keep the oxides produced by the reaction of molten metal and air in the pouring chamber, improve the quality of metal castings after pouring, and have extremely high economic value for the production of metal castings.

[0004] The above technical solution starts the motor to drive the rocker to rotate, flips the pouring frame from a horizontal state to a vertical state, and then leaves the residue inside the pouring chamber through the pouring chamber and the guide block, so that the molten metal can smoothly enter the mold. However, the pouring is done in a top pouring manner, which inevitably causes the casting to converge, so that the casting is prone to the defect of subcutaneous pores, resulting in poor casting quality. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a manual pouring device for metal mold castings. When the motor is started, the second module is driven to close with the first module. The molten metal will flow from the pouring pipe at the bottom end of the pouring cylinder to the cavity between the first module and the second module, and the gas in the cavity and the gas generated during pouring will be discharged from the exhaust hole, thereby reducing the occurrence of air holes in the casting and improving the quality of the casting.

[0006] The technical solution to achieve the purpose of the utility model is: a manual pouring device for metal mold castings, including a base, a first module is fixedly installed on the top wall of the base, a second module is slidably installed on the top wall of the base, the positions of the first module and the second module correspond, and also includes;

[0007] A pouring pipe, wherein the pouring pipe is arranged at the bottom end of the outer side wall of the first module, the other end of the pouring pipe is fixedly connected with a pouring cylinder, four supporting rods are fixedly installed on the outer bottom wall of the pouring cylinder, an exhaust hole is arranged on the top wall of the second module, a supporting plate is fixedly installed on the top wall of the base, a protective cover is arranged on the right side of the supporting plate, a motor is fixedly installed on the inner side wall of the protective cover, a threaded rod is fixedly installed on the output end of the motor, and the threaded rod passes through the supporting plate and is rotatably connected with the right side wall of the second module.

Since the threaded rod is spirally connected to the support plate, and the support plate is fixed on the top wall of the base, the threaded rod will rotate and move to the left along the thread direction at this time. As the threaded rod moves, it will drive the second module to move to the left, so that the second module and the first module are closed, and then the molten metal is poured from the pouring barrel. The molten metal will flow from the pouring pipe to the cavity between the first module and the second module, and the gas in the cavity and the gas generated during pouring will be discharged from the exhaust hole, thereby reducing the occurrence of air holes in the casting and improving the quality of the casting; solving the problem of poor casting quality of the existing manual pouring device for metal mold castings.

[0017] Secondly: when pouring, the utility model first holds the fixing rod to place the limit block in the limit groove of the limit rod, and places the filter cartridge stably. Then the molten metal will be filtered from the filter cartridge first, which can block the raw material slag and furnace slag that are not completely liquefied, and prevent the raw material slag and furnace slag that are not completely liquefied from being injected into the cavity through the pouring pipe, thereby improving the quality of the casting. After the pouring device is used, the fixing rod is hooked with an external tool and pulled upward, so that the filter cartridge can be directly taken out, which is convenient for collecting and processing the filtered furnace slag and unformed raw material slag.
