Description

Technical Field

[0001] This utility model relates to the field of pouring cup technology, and in particular to a stepped pouring cup for simultaneous open valve casting. Background Technology

[0002] In the casting process, the pouring cup, also known as the "pouring basin," is the core front-end component of the gating system. It refers to a transitional container specially designed to receive the high-temperature liquid metal poured from the ladle and smoothly guide it into the subsequent sprue. It is the first "transfer station" before the molten metal enters the mold cavity.

[0003] When pouring, the high-temperature molten metal directly impacts the bottom of the existing pouring cup, which in turn agitates the air inside the cup to form a vortex. This air can easily enter the mold with the molten metal, which may cause porosity in the casting and affect the processing quality of the casting. At the same time, the opening size of the discharge port of the existing pouring cup cannot be adjusted, so the flow rate of the molten metal cannot be controlled. Utility Model Content

[0004] The purpose of this invention is to provide a stepped pouring cup for simultaneous open valve casting, which solves the problems of existing pouring cups where high-temperature molten metal directly impacts the bottom of the cup during pouring, thereby agitating the air inside the cup to form vortices, resulting in porosity in the casting and affecting the quality of the casting, as well as the inability to adjust the opening size of the discharge port of existing pouring cups and control the flow rate of molten metal.

[0005] To achieve the above objectives, a stepped pouring cup for simultaneous open valve casting is provided, comprising: a pouring cup body, wherein a filter screen is movably installed inside the pouring cup body to facilitate the filtration of molten metal, a discharge port is provided at the bottom of the pouring cup body, and mounting plates are fixedly connected to both sides of the discharge port, a support rod is fixedly connected to one side of the two mounting plates, and another mounting plate is fixedly connected to the other end of the support rod, a screw is rotatably connected inside the mounting plate on the front side, and a baffle is movably connected to the outer wall of the screw and the support rod to facilitate the adjustment of the discharge port size, thereby facilitating the control of the flow rate of molten metal.

[0006] According to the stepped pouring cup of the simultaneous open valve casting method, the inner wall of the pouring cup body is set with a stepped structure, which facilitates multi-stage buffering of molten metal and reduces the possibility of eddy currents.

[0007] According to the stepped pouring cup of the simultaneous open valve casting method, the shape and size of the filter screen are matched with the shape and size of the bottom wall of the pouring cup body, which facilitates the filtration of impurities in the molten metal and improves the subsequent processing effect of the casting.

[0008] According to the stepped pouring cup cast with a single open valve, the top of the filter screen and the bottom wall of the pouring cup body are both provided with mounting holes, and the mounting holes are connected by positioning bolts to facilitate the installation and removal of the filter screen.

[0009] According to the stepped pouring cup of the simultaneous open valve casting, a groove is provided on the side of the discharge port. The shape and size of the groove are matched with the shape and size of the baffle. The baffle is slidably connected to the inner wall of the groove, which facilitates the adjustment of the discharge port opening size and thus facilitates the control of the flow rate of the molten metal.

[0010] According to the stepped pouring cup of the all-open valve casting, the side of the baffle is provided with a screw hole, and the inner wall of the screw hole and the outer wall of the screw rod are both provided with threads. The screw hole and the screw rod are engaged with each other through the threads to facilitate the movement of the baffle.

[0011] According to the stepped pouring cup of the all-open valve casting, guide holes are provided at both ends of the side of the baffle. The baffle is slidably connected to the outer wall of the support rod through the guide holes, which facilitates the guiding and limiting of the baffle.

[0012] According to the stepped pouring cup of the all-open valve casting, a rotating shaft seat is fixedly installed on the inner side of the mounting plate on the front side, and one end of the screw is rotatably connected to the rotating shaft seat to facilitate the rotation of the screw.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. This stepped pouring cup achieves graded buffering of molten metal by setting a stepped structure on the inner wall of the pouring cup body, avoiding excessive flow rate of molten metal, prolonging the residence time of molten metal in the cup body, and thus improving the slag-blocking effect of molten metal. At the same time, by setting a filter screen on the bottom wall of the pouring cup, impurities in molten metal can be filtered out, thereby improving the processing quality of subsequent castings.

[0015] 2. This stepped pouring cup features mounting plates on both sides of the discharge port, with a screw rotatably connected inside the left mounting plate. The outer wall of the screw is fitted with a baffle. Rotating the two screws moves the two baffles within the chute, allowing adjustment of the discharge port opening size by varying the distance between the two baffles. This facilitates control of the molten metal flow rate, meeting the flow rate requirements of different castings and enhancing the practicality of the stepped pouring cup.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

By rotating the screw 9, the baffle 11 on its outer wall can be moved, thereby adjusting the opening size of the discharge port 5 by adjusting the distance between the two baffles 11, facilitating the adjustment of the molten metal flow rate.

[0028] The inner wall of the pouring cup body 1 is designed with a stepped structure. The stepped structure can provide multi-level buffering for the molten metal, thereby reducing the impact of the molten metal on the bottom of the pouring cup body 1 and reducing the possibility of eddy currents.

[0029] The shape and size of the filter screen 2 are matched with the shape and size of the bottom wall of the pouring cup body 1. Impurities in the molten metal can be filtered through the filter screen 2.

[0030] The top of the filter screen 2 and the bottom wall of the pouring cup body 1 are both provided with mounting holes 3, and the mounting holes 3 are connected by positioning bolts 4, which facilitates the installation and disassembly of the filter screen 2, and thus facilitates the replacement of the filter screen 2.

[0031] A groove 6 is provided on the side of the discharge port 5. The shape and size of the groove 6 match the shape and size of the baffle 11. The baffle 11 is slidably connected to the inner wall of the groove 6, which facilitates the adjustment of the opening size of the discharge port 5.

[0032] The side of the baffle 11 is provided with a screw hole 12. The inner wall of the screw hole 12 and the outer wall of the screw 9 are both provided with threads. The screw hole 12 and the screw 9 are engaged with each other through threads. When the screw 9 is rotated, the baffle 11 can be moved, which facilitates the adjustment of the opening size of the discharge port 5.

[0033] Guide holes 13 are provided at both ends of the side of the baffle 11. The baffle 11 is slidably connected to the outer wall of the support rod 8 through the guide holes 13. The support rod 8 can guide and limit the baffle 11.

[0035] Working principle: During casting, when the molten metal enters the pouring cup body 1, it is subjected to the multi-stage buffering effect of the stepped structure, which reduces the impact on the bottom of the pouring cup body 1, reduces the possibility of eddy current generation, and prolongs the residence time of the molten metal in the pouring cup body 1, thereby improving the slag-blocking effect of the pouring cup body 1, which facilitates the subsequent processing of the casting. In addition, the bottom wall of the pouring cup body 1 is equipped with a filter screen 2, which can filter impurities in the molten metal, improving the processing quality of the subsequent casting.

[0036] When it is necessary to adjust the opening size of the discharge port 5, rotating the two screws 9 can drive the two baffles 11 to move within the chute 6. In turn, the opening size of the discharge port 5 can be adjusted by adjusting the distance between the two baffles 11, thereby adjusting the flow rate of the molten metal to meet the flow rate requirements of different castings.
