Description

Technical Field

[0001] The invention relates to the technical field of mold casting, in particular to a mold casting device for casting production. Background Art

[0002] During traditional pouring, the mold is often simply placed on a workbench, and its position is only roughly adjusted manually. There is a lack of precise positioning structure. For example, small foundry workshops use simple clamps or sandbags to fix the mold. The impact of molten metal during pouring can easily cause the mold to shift, resulting in large dimensional deviations of the castings and a high scrap rate. Large and complex molds have a more prominent displacement problem due to their own weight and pouring force, affecting product quality stability and production efficiency.

[0003] After long-term use, the exhaust holes of traditional equipment may be blocked due to external factors, thereby reducing the efficiency of pouring. At the same time, in hot weather, the cast model may dissipate heat slowly due to environmental factors, which also reduces work efficiency.

[0004] In view of this, research and improvement are carried out on the existing problems, and a mold casting device for casting production is provided, which has a reasonable structural design, high stability, and takes into account all aspects of application. The purpose is to solve the problem and improve the practical value through this technology. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Reference Figure 1-4 , an embodiment of the present invention: a mold casting device for casting production, comprising a base 1, a guide groove 2 for improving stability is opened on the upper surface of the base 1, a reciprocating screw 3 is arranged inside the guide groove 2, a bearing 4 for movement is movably connected to the outer side of the reciprocating screw 3, a motor 5 for driving is fixedly connected to one end of the base 1, a first mold plate 6 for shaping is connected to the upper end of the bearing 4, a first mold plate 6 is fixedly connected to one side of the first mold plate 6, a casting pipe 8 for casting is fixedly connected to the upper end of the second mold plate 7, and a casting pipe 8 is fixedly connected to the outer side of the casting pipe 8 A fixed fixing ring 9, a rack 10 is fixedly connected to the lower end of the fixing ring 9, a one-way valve 11 is fixedly connected to the outer side of the casting tube 8 at the upper end of the first mold plate 6, a gear 12 for controlling the opening and closing is arranged on the outer side of the one-way valve 11, a connecting port 13 for cooling is arranged on one side of the first mold plate 6, a connecting pipe 14 for air intake is fixedly connected to one end of the connecting port 13, a spring rod 15 for resetting is fixedly connected to the outer side of the connecting pipe 14, a connecting rod 16 is fixedly connected to the upper end of the spring rod 15, and a connecting block 17 for unblocking the inside of the connecting pipe 14 is fixedly connected to one end of the first mold plate 6.

[0018] In an optional embodiment: the guide groove 2 is opened at the center of the upper surface of the base 1, which does not completely penetrate the base 1, and slide grooves are opened on both sides of the guide groove 2, the reciprocating screw 3 is fixedly connected to the inside of the guide groove 2, and one end of the reciprocating screw 3 penetrates the base 1 and extends to the outer end, and two groups of bearings 4 are arranged on the outside of the reciprocating screw 3, and the bearings 4 are connected to the ball nut pair of the reciprocating screw 3, and protrusions are fixedly connected on both sides of the bearings 4, and the bearings 4 are connected to the slide groove for positioning through the protrusions, and when the bearing 4 moves, it is limited inside the slide groove by the protrusions at both ends. At the same time, when the bearing 4 moves, the protrusions also play a guiding role when moving inside the slide groove, thereby improving the smoothness during operation and preventing the first mold plate 6 from being misaligned with the second mold plate 7 due to offset during movement, resulting in reduced sealing.

[0019] In an optional embodiment: the motor 5 is fixedly connected to one end of the base 1, which is connected to the output end and one end extending from the reciprocating screw 3, and the reciprocating screw 3 is rotated by the drive of the motor 5, the first mold plate 6 is fixedly connected to the upper end of the bearing 4, and the second mold plate 7 is fixedly connected to the upper end of another group of bearings 4, and the interiors of the first mold plate 6 and the second mold plate 7 are both hollow. When in use, the reciprocating screw 3 is driven to rotate by the motor 5. When the reciprocating screw 3 rotates, since the first mold plate 6 and the second mold plate 7 are fixedly connected to the bearing 4, the two groups of bearings 4 will be driven to move inward, thereby merging the first mold plate 6 and the second mold plate 7 into a whole.

[0020] In an optional embodiment: the casting tube 8 is divided into two halves, and the first mold plate 6 and the second mold plate 7 have one half fixedly connected at their upper ends. The outer side of the casting tube 8 at the upper end of the second mold plate 7 is fixedly connected to a fixing ring 9, and the outer diameter of the fixing ring 9 matches the outer diameter of the casting tube 8. The lower end of the fixing ring 9 is fixedly connected to a rack 10 meshing with a gear 12. When the first mold plate 6 and the second mold plate 7 are merged, since the rack 10 and the gear 12 are in the same plane, the gear 12 will be driven to rotate by the rack 10 on one side when the casting tube 8 is merged. Since the gear 12 is connected to the internal valve of the one-way valve 11, the internal valve of the one-way valve 11 will be opened when the gear 12 rotates, so that the hot air can be discharged through the one-way valve 11 during casting, thereby increasing the flow rate of the molten iron and preventing the molten iron from flowing slowly due to excessive hot air.

[0021] In an optional embodiment: the pouring tube 8 at the upper end of the first mold plate 6 is fixedly connected to the one-way valve 11, and the outer side of the one-way valve 11 is connected to the gear 12 through a connecting rod, and the connecting rod penetrates the one-way valve 11 and is connected to the internal valve, the gear 12 and the rack 10 are in the same horizontal plane, and the gear 12 is driven by the rack 10 to rotate. During demolding, the rack 10 drives the gear 12 to rotate, so that it automatically closes the internal valve of the one-way valve 11, thereby preventing dust from entering the one-way valve 11 and causing the one-way valve 11 to be blocked when the first mold plate 6 and the second mold plate 7 are opened, and preventing the one-way valve 11 from being blocked due to long-term exposure to the outside, thereby preventing the hot air from being discharged.

[0022] In an optional embodiment: the connecting port 13 is fixedly connected to one side of the first mold plate 6 and the second mold plate 7, and there are two groups of them. The connecting port 13 is connected to the hollow part inside the first mold plate 6 and the second mold plate 7, and the connecting pipe 14 is fixedly connected to the connecting port 13 near the lower end. During pouring, by connecting one end of the connecting pipe 14 to the fan, the first mold plate 6 and the second mold plate 7 are blown into the inside through the connecting pipe 14 when in use. At the same time, because the inside of the first mold plate 6 and the second mold plate 7 are hollow, the air entering will be discharged through the connecting port 13 at the upper end, so that the heat inside the mold can be quickly discharged, while also accelerating the cooling speed of the mold and improving the manufacturing efficiency.

[0023] In an optional embodiment: the spring rod 15 passes through the connecting tube 14 and is connected to the internal valve. The upper end of the spring rod 15 is fixedly connected to the connecting rod 16. The connecting block 17 is fixedly connected to the lower end of the first mold plate 6. The valve inside the connecting tube 14 is squeezed open when the connecting block 17 moves. When the first mold plate 6 moves toward the center, the connecting block 17 is connected to the first mold plate 6, so it will drive the connecting block 17 to move synchronously. When the connecting block 17 moves to contact with the connecting rod 16, the spring rod 15 is a movable connection. When the connecting block 17 squeezes the connecting rod 16, the connecting rod 16 will flip over, so that when the connecting rod 16 flips over, it will drive the spring rod 15 to rotate synchronously, thereby opening the valve inside the connecting pipe 14, so that the inside can be cooled down when the molds are merged. When the mold is opened, the first mold plate 6 moves backward and drives the connecting block 17 to move, so that the connecting block 17 is out of contact with the connecting rod 16, so that the connecting rod 16 will automatically rebound with the elastic force of the spring rod 15, and the spring rod 15 will drive the connecting rod 16 to reset while rebounding.

[0024] Working principle and process: When in use, the reciprocating screw 3 is driven to rotate by the motor 5. When the reciprocating screw 3 rotates, because the first mold plate 6 and the second mold plate 7 are fixedly connected to the bearing 4, the bearing 4 is driven by the reciprocating screw 3 to move, which will drive the first mold plate 6 and the second mold plate 7 to merge into a whole. Because the rack 10 and the gear 12 are in the same plane, when the casting pipe 8 is merged, the gear 12 will be driven to rotate through the rack 10 on one side. Because the gear 12 is connected to the internal valve of the one-way valve 11, Therefore, when the gear 12 rotates, the valve inside the one-way valve 11 will be opened. At the same time, when the first mold plate 6 moves toward the center, since the connecting block 17 is connected to the first mold plate 6, it will drive the connecting block 17 to move synchronously. When the connecting block 17 moves to contact the connecting rod 16, since the spring rod 15 is a movable connection, the connecting rod 16 will be flipped when the connecting block 17 squeezes the connecting rod 16, so when the connecting rod 16 flips, it will drive the spring rod 15 to rotate synchronously, thereby opening the valve inside the connecting pipe 14.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
