[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0031] Example 1

[0032] like Figure 1 to Figure 7As shown, this embodiment proposes an efficient casting device with reduced defects, including a housing 2 and a filter assembly 1, the bottom of the housing 2 is fixedly connected to a bottom plate 6, a control panel 5 is installed on one side of the housing 2, and cooling fans 3 are installed on both sides of the housing 2. The filter assembly 1 includes a driven gear 104, the driven gear 104 is rotatably installed on the top of the housing 2, the top of the driven gear 104 is fixedly connected to a connecting rod 105, and two symmetrically arranged placement plates 106 are fixedly connected to the connecting rod 105. The placement plates 106 are used to place the filter screen, and the two placement plates 106 are fixedly connected to a top block 107. The top of the housing 2 A feed port 4 is fixedly connected, and a discharge plate 12 is fixedly connected to the interior of the outer shell 2. Through the arrangement of structures such as a placement plate 106 and a placement cylinder 109, a filter is arranged on the placement plate 106 just above the feed port 4, so that liquid metal can be filtered when it is injected into the feed port 4. After use once, automatic replacement is achieved through the rotation of the driven gear 104. During the rotation, the used filter is removed by the extrusion block 113, and the new filter in the placement cylinder 109 is dropped into the placement plate 106 by squeezing the movable plate 110, thereby achieving the effect of automatically replacing the filter to improve the casting quality.

[0033] like Figure 1 to Figure 7 As shown, an extension plate 114 is fixedly connected to one side of the housing 2, a driving motor 101 is installed at the bottom of the extension plate 114, the driving motor 101 is electrically connected to the control panel 5, the output end of the driving motor 101 is fixedly connected to a coaxially arranged rotating rod 102 through a coupling, the rotating rod 102 is rotatably installed inside the extension plate 114, a driving gear 103 is rotatably installed on the top of the extension plate 114, the bottom of the driving gear 103 is fixedly connected to the top of the rotating rod 102, and the driving gear 103 is meshingly connected to the driven gear 104.

[0034] like Figure 1 to Figure 7 As shown, a squeezing block 113 is fixedly connected to the top of the shell 2. The top of the squeezing block 113 is arc-shaped. The squeezing block 113 is used to remove the filter screen inside the placement plate 106. A storage plate 112 is fixedly connected to one side of the shell 2.

[0035] like Figure 1 to Figure 7 As shown, one side of the shell 2 is fixedly connected to the bracket 108, the top of the bracket 108 is fixedly connected to the placement tube 109, one side of the bracket 108 is fixedly connected to two symmetrically arranged telescopic rods 115, one end of the two telescopic rods 115 is commonly fixedly connected to a movable plate 110, a contraction spring 111 is arranged on the outside of the telescopic rod 115, both ends of the contraction spring 111 are respectively welded between the bracket 108 and the movable plate 110, the bottom end of the movable plate 110 is used to contact with the top block 107, and the top end of the movable plate 110 extends into the interior of the placement tube 109.

[0036] In this embodiment, the entire device is first placed in a factory. When work is required, the molten metal is injected into the internal casting mold 10 through the feed port 4. During the injection process, a new filter screen needs to be replaced each time the filter screen is injected. The filter screen can filter impurities in the metal solution to avoid major defects in the finished product. However, the filter screen needs to be discarded each time it is used. Therefore, after one use, the control panel 5 is used to start the drive motor 101. The drive motor 101 drives the active gear 103 to rotate. The active gear 103 and the driven gear 104 are engaged to realize the rotation of the connecting rod 105. When the connecting rod 105 rotates, it drives the two placement plates 106 to rotate. The filter screen is placed in advance inside the two placement plates 106 just above the feed port 4. During the rotation and switching process after use, the bottom of the filter screen will be squeezed by the squeezing block 113. Since the filter screen itself has a certain elasticity, it will be squeezed after being squeezed. After that, it will pop out from the interior of the placement plate 106 and enter the interior of the storage plate 112 for unified processing. The placement plate 106 continues to rotate. When it rotates to the placement cylinder 109, multiple filters are placed inside the placement cylinder 109. The bottom filter is restricted by the movable plate 110 and will not fall. When the placement plate 106 rotates to the placement cylinder 109, the top block 107 on the placement plate 106 will push the movable plate 110, so that the filter loses its restriction and automatically falls into the interior of the placement plate 106, thereby completing the entire automatic replacement process. The movable plate 110 will automatically reset by the contraction spring 111 when the top block 107 leaves. After the movable plate 110 is reset, it continues to limit the filter behind. This part avoids the danger of manual labor and the problem of low manual efficiency through the automatic replacement of the filter. At the same time, the defect of the finished product is reduced by the effect of replacing the filter every time.

[0037] Example 2

[0038] like Figure 1 to Figure 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a protective shell 7 is fixedly connected to one side of the outer shell 2, a driving motor 8 is installed on one side of the protective shell 7, and the output end of the driving motor 8 is fixedly connected to a coaxially arranged bidirectional screw 9 through a coupling, and the bidirectional screw 9 is rotatably installed inside the protective shell 7. Through the arrangement of structures such as the bidirectional screw 9 and the casting mold 10, when the metal liquid is injected into the casting mold 10 through the feed port 4, the cooling fan 3 is used to quickly cool it down and form it. After forming, the two casting molds 10 are automatically separated by the bidirectional screw 9, thereby achieving a simpler and more practical demolding effect.

[0039] like Figure 1 to Figure 7As shown, a communicating movable groove is provided between the protective shell 7 and the outer shell 2, two opposite threads are provided on the bidirectional screw 9, the outsides of the two opposite screws are assembled with a casting mold 10 through a ball nut, the two casting molds 10 are both slidably connected to the inside of the movable groove, one side of the two casting molds 10 is fixedly connected to a limiting plate 11, a limiting groove is provided inside the outer shell 2, and the two limiting plates 11 are both slidably connected to the inside of the limiting groove.

[0040] In this embodiment, after the metal liquid is injected into the mold 10, it will start to form inside the mold 10. In order to speed up the forming speed, the two cooling fans 3 are started through the control panel 5 to heat the air circulation and provide sufficient cooling, thereby achieving rapid forming and improving work efficiency. After forming, the drive motor 2 8 is started through the control panel 5 to drive the rotation of the bidirectional screw 9. The bidirectional screw 9 drives the two molds 10 to move in opposite directions, and the demolding effect can be directly completed. After demolding, the finished product will fall onto the blanking plate 12 inside the shell 2. The surface of the blanking plate 12 is provided with a sponge for protection to avoid damage to the finished product during the falling process. Limiting plates 11 are also provided on both sides of the mold 10. The limiting plates 11 can prevent the mold 10 from falling due to excessive weight, and also reduce the pressure of the bidirectional screw 9.

[0041] Example 3

[0042] like Figure 1 to Figure 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a driving motor 3 13 is installed on one side of the bottom plate 6, and two symmetrically arranged conveying rollers 14 are rotatably installed inside the bottom plate 6. The driving motor 3 13 is fixedly connected to one of the conveying rollers 14 through a coupling, and a conveyor belt 15 is commonly sleeved on the outside of the two conveying rollers 14. The driving motor 3 13 is electrically connected to the control panel 5, and electric control cylinders 21 are installed on both sides of the bottom plate 6. The electric control cylinder 21 is electrically connected to the control panel 5, and a baffle 22 is fixedly connected to the output end of the electric control cylinder 21. Through the arrangement of structures such as the baffle 22 and the water spray head group 20, the finished product moves to the conveyor belt 15 after demoulding, and can only stay in place due to the restriction of the baffle 22. When the finished product is completely cleaned by the water spray head group 20, the baffle 22 is moved, and the finished product will not be transmitted until it loses the limit, thereby achieving a more complete cleaning effect.

[0043] like Figure 1 to Figure 7As shown, a fixed plate 16 is fixedly connected to the top of the base plate 6, and a reciprocating screw 17 is rotatably installed inside the fixed plate 16. One end of the reciprocating screw 17 passes through the inside of the fixed plate 16, and the protruding end of the reciprocating screw 17 and the outside of one of the conveying rollers 14 are jointly sleeved with a synchronous belt 18 through a synchronous wheel. The outside of the reciprocating screw 17 is equipped with a transmission sleeve 23 through a ball nut, and a sprinkler head group 20 is installed at the bottom of the transmission sleeve 23. A water tank 19 is fixedly connected to the top of the fixed plate 16, and a water pump is arranged inside the water tank 19. The water pump is electrically connected to the control panel 5, and the water tank 19 and the sprinkler head group 20 are connected by a flexible hose.

[0044] In this embodiment, when the finished product falls onto the blanking plate 12, it will move to the conveyor belt 15. Before that, the control panel 5 drives the electric control cylinder 21 to extend and retract to adjust the position of the baffle 22, ensuring that the finished product can be limited to avoid being transported out of the conveyor belt 15 too early. When the finished product is limited, since the conveyor belt 15 has been started, it means that the conveyor roller 14 is also rotating. At this time, the drive motor 3 13 is in a working state. The setting of the synchronous belt 18 can drive the reciprocating screw rod 17 to rotate, thereby realizing the reciprocating movement of the transmission sleeve 23 along the direction of the thread, thereby driving the water spray head group 20 to be unable to move. In this process, the control Panel 5 starts the water pump inside the water tank 19, and transports water to the inside of the water spray head group 20 through a flexible hose to reciprocately clean the surface of the finished product. The preliminary cleaning is more conducive to the subsequent processing of the surface of the finished product. After complete cleaning, the control panel 5 controls the electric cylinder 21 to drive the baffle 22 to retract. At this time, the finished product loses the limit of the baffle 22 and leaves the casting equipment through the conveyor belt 15. This part mainly improves the quality of the product through the complete cleaning work after the finished product is formed, and provides complete preparation for subsequent processes. It should be noted that the water used to clean the finished product can be collected by placing a sink or directly discharged.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
