Description

Technical Field

[0001] This utility model relates to the field of core sand processing technology, and in particular to a novel core shooting machine. Background Technology

[0002] Core sand uses oil sand, CO2-dried sand, and shell core sand materials. In the mold, the core is mostly surrounded by high-temperature liquid metal, while the size of the supporting and positioning parts is generally small. Therefore, in addition to having the properties of general molding sand, core sand also requires high strength, permeability, collapsibility, and collapse resistance. A core shooter is a special equipment used in the foundry industry, mainly used to manufacture sand cores. Sand core forming is mainly achieved by injecting resin sand into the mold cavity under high pressure to quickly form a precise sand core structure, which is used to cast the hollow parts of metal parts.

[0003] To address this, patent publication CN213002512U discloses a novel core-shooting machine, comprising a housing, fixed posts at the corners of the upper surface of the housing, a drive box at the top of the fixed posts, an adjustable moving module below the drive box, a fixed module at the corresponding position of the moving module on the upper surface of the housing, injection plates on both sides of the fixed module on the upper surface of the housing, an outer plate at the corresponding position of the fixed module on the front surface of the housing, a main slide groove on the upper surface of the outer plate, an adjustable movable plate within the main slide groove, and a collection groove on the upper surface of the movable plate near the fixed module. This novel core-shooting machine, by setting an outer plate at the front of the housing and a movable plate above the outer plate, utilizes the movement of the movable plate to reach below the fixed module, thereby collecting the falling product and improving the work efficiency of the operator.

[0004] The aforementioned new core shooting machine proposes to set an external plate in front of the outer shell and a movable plate above the external plate. The movable plate moves to reach the bottom of the fixed module to collect the falling products, thereby improving the work efficiency of the operators. However, when using it, sand of various materials may be used. The sand is not mixed stably enough inside the sand box, and the sand may also solidify inside the sand box. Utility Model Content

[0005] The purpose of this invention is to provide a new type of core shooter to solve the problem that existing core shooters are difficult to mix sand.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel core shooting machine, including a housing;

[0007] A workbench is installed on the top of the box, a second mold is installed on the top of the workbench, a first mold is provided on one side of the top of the workbench, and an installation frame is installed on the top of the workbench.

[0008] A core-shooting cylinder is installed at the top of the mounting frame, and a core-shooting port is installed at the bottom of the core-shooting cylinder. A sand box is installed on one side of the top of the mounting frame, and an inlet is installed at the top of the sand box, with a cover installed at the top of the inlet.

[0009] The sand box is equipped with a stirring mechanism, which includes a servo motor installed at the bottom of the sand box and a stirring shaft installed at the top of the servo motor.

[0010] In use, the inlet can first be sealed with the cover, and the sand can be loaded into the sand box through the cover. The operation of the first hydraulic cylinder will drive the extension and retraction of the first hydraulic rod, which will drive the first mold to move. The movement of the first mold will engage the first mold and the second mold together. The guide rod can prevent the first mold from deviating during movement. The operation of the core-shooting cylinder will absorb the sand and spray it out from the core-shooting port at the bottom. The core-shooting port is aligned with the inlet at the top of the mold. The operation of the heating wire can heat the inside of the mold. The sand core can be inserted into the mold through the top of the mold for thermoforming.

[0011] Furthermore, a moving mechanism is installed on one side of the first mold. The moving mechanism includes an installation plate installed on the top of the workbench, a first hydraulic cylinder installed on one side of the installation plate, and a first hydraulic rod installed on one side of the first hydraulic cylinder. Guide rods pass through both ends of the installation plate. The moving mechanism can drive the first mold to move.

[0012] Furthermore, the guide rods are symmetrically distributed about the central axis of the mounting plate, and the guide rods and the mounting plate form a sliding structure, so that the guide rods can guide the movement of the first mold.

[0013] Furthermore, a heating wire is embedded inside the first mold. The heating wire is serpentine in shape and can heat the inside of the mold.

[0014] Furthermore, a discharge mechanism is installed on one side of the second mold. The discharge mechanism includes a fixed plate installed on one side of the top of the workbench, a second hydraulic cylinder installed on one side of the fixed plate, a second hydraulic rod installed on one side of the second hydraulic cylinder, and a push plate installed on one side of the second hydraulic cylinder. The discharge mechanism can drive the processed sand core to be discharged.

[0015] Furthermore, a stirring blade is installed on the outer side of the stirring shaft, a rotating shaft is installed at the top of the stirring shaft, a connecting rod is installed at the top of the rotating shaft, brushes are installed at both the top and bottom of the connecting rod, and a screen is installed on the outer side of the connecting rod. The stirring blade can stir the inside of the sand box.

[0016] Furthermore, a scraper is installed on the outer side of the stirring blade. The scraper is arranged in a ring and can scrape the material inside the sand box.

[0017] The advantages of the novel core shooting machine provided by this utility model are: during use, the sand box can be stirred by the stirring mechanism to mix the sand materials, the shaped sand materials can be automatically discharged by the discharge mechanism, and the first mold can be automatically moved by the moving mechanism.

[0018] By installing a servo motor at the bottom of the sand box, the servo motor drives the stirring shaft to rotate, which in turn drives the stirring blades to rotate. The rotating blades stir the sand inside the sand box, allowing various materials to mix together. The rotating blades also drive the scraper to rotate, cleaning the inner wall of the outer shell and preventing materials from adhering to it. When the sand enters the sand box through the inlet, it can be filtered through a screen. The rotation of the stirring shaft drives the rotating shaft to rotate. The connecting rod at the top of the rotating shaft passes through the screen. The brushes at the top and bottom of the connecting rod clamp the screen in the middle. When the rotating shaft rotates and drives the connecting rod to rotate, the connecting rod rotates and drives the brushes to rotate, cleaning the screen surface and preventing clogging. This achieves the purpose of the new core shooter for easy stirring of sand.

[0019] By installing a fixed plate on one side of the top of the workbench, the operation of the second hydraulic cylinder on one side of the fixed plate will drive the second hydraulic rod to extend and retract. The extension and retraction of the second hydraulic rod will drive the push plate to move. After the processing is completed, the first mold moves away, and the sand core will remain inside the second mold. The movement of the push plate will push out the sand core after the processing is completed, making it easier for the sand core to be discharged and preventing blockage during the discharge of the sand core. This achieves the purpose of the new core shooting machine to facilitate the discharge of materials. Attached Figure Description

[0029] See attached document Figure 1-2 As shown, the operation of the second hydraulic cylinder 701 on one side of the fixed plate 704 will drive the second hydraulic rod 702 to extend and retract. The extension and retraction of the second hydraulic rod 702 will drive the push plate 703 to move. After the processing is completed, the first mold 5 moves away, and the sand core will remain inside the second mold 6. The movement of the push plate 703 will push out the sand core after the processing is completed, making it easier for the sand core to be discharged and preventing blockage when the sand core is discharged.

[0030] A first mold 5 is provided on one side of the top of the workbench 1. A heating wire 14 is embedded inside the first mold 5. The heating wire 14 is serpentine in shape.

[0031] A moving mechanism 2 is installed on one side of the first mold 5. The moving mechanism 2 includes a mounting plate 201 installed on the top of the workbench 1, a first hydraulic cylinder 203 installed on one side of the mounting plate 201, and a first hydraulic rod 204 installed on one side of the first hydraulic cylinder 203. Guide rods 202 pass through both ends of the mounting plate 201. The guide rods 202 are symmetrically distributed about the central axis of the mounting plate 201. The guide rods 202 and the mounting plate 201 form a sliding structure.

[0032] See attached document Figure 1 and attached Figure 5 As shown, the inlet 12 can be sealed by the cover 11, and the sand can be loaded into the sand box 10 by the cover 11. Then, the first hydraulic cylinder 203 will work to drive the first hydraulic rod 204 to extend and retract. The extension and retraction of the first extension rod will drive the first mold 5 to move. The movement of the first mold 5 will make the first mold 5 and the second mold 6 fit together. The guide rod 202 can prevent the first mold 5 from deviating when it moves. After the first mold 5 and the second mold 6 are closed, the core shooting cylinder 9 will work to absorb the sand and spray it out from the core shooting port 8 at the bottom. The core shooting port 8 is aligned with the inlet 12 at the top of the mold. The heating wire 14 can work to heat the inside of the mold. The sand core can be inserted into the mold through the top of the mold for thermoforming.

[0033] A mounting frame 4 is installed at the top of the workbench 1. A core-shooting cylinder 9 is installed at the top of the mounting frame 4. A core-shooting port 8 is installed at the bottom of the core-shooting cylinder 9. A sand box 10 is installed on one side of the top of the mounting frame 4. An inlet 12 is installed at the top of the sand box 10, and a cover 11 is installed at the top of the inlet 12.

[0036] See attached document Figure 1 and attached Figure 3-4As shown, the servo motor 1302 drives the stirring shaft 1303 to rotate, which in turn drives the stirring blade 1304 to rotate. The rotation of the stirring blade 1304 stirs the sand inside the sand box 10, allowing various materials to mix together. The rotation of the stirring blade 1304 also drives the scraper 1305 to rotate, which cleans the inner wall of the outer shell, preventing materials from adhering to it. When the sand enters the sand box 10 through the inlet 12, it can pass through the screen 130. 1. When the sand is filtered, the rotating shaft 1303 will drive the rotating shaft 1308 to rotate. The connecting rod 1306 at the top of the rotating shaft 1308 passes through the screen 1301. The brushes 1307 at the top and bottom of the connecting rod 1306 can clamp the screen 1301 in the middle. When the rotating shaft 1308 rotates and drives the connecting rod 1306 to rotate, the rotation of the connecting rod 1306 will drive the brush 1307 to rotate. The rotation of the brush 1307 can clean the surface of the screen 1301 and prevent the screen 1301 from becoming clogged.
