Description

Technical Field

[0001] The present invention relates to the technical field of casting devices, and in particular to a precision casting automatic casting device. Background Art

[0002] Casting is a process of heating metal and then shaping it. At the same time, the pouring process is a process of heating metal to a molten state and then injecting it into a mold for casting.

[0003] Existing precision casting automatic casting devices generally use an integrated upper mold in cooperation with an integrated lower mold for casting operations. In this way, the cast mold is extremely likely to get stuck with the integrated upper mold and needs to be removed manually, which affects work efficiency. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a precision casting automatic casting device to solve the problems raised in the above background art. To achieve the above objectives, the present invention is realized through the following technical solutions: A precision casting automatic casting device includes a base. In the middle of the top of the base, a cylindrical mold is fixed. On the outer side of the top of the base, three support rods are fixed. At the top of the three support rods, a frustum is fixed. At the top of the frustum, a multi-track linear motor is fixed. An extensible feeding pipe is embedded in the frustum. By setting the extensible feeding pipe, it is convenient to cast the entire combined mold. Three track grooves are opened on the frustum. At the top of the frustum, three stop rods are fixed, and the three stop rods are respectively located above the three track grooves. Three outer mold components are arranged inside the frustum. The outer mold component includes a slider. The slider is slidably connected to the track groove of the frustum. The top of the slider is connected to the moving shaft of the multi-track linear motor through a connecting plate. A vertical rod is rotatably connected inside the slider. At the bottom of the vertical rod, an outer mold is fixed. After casting is completed, the multi-track linear motor is started. The slider is controlled to slide in the track groove through the connecting plate, so that the vertical rod drives the outer mold to move horizontally. Subsequently, after the vertical rod is blocked by the stop rod, it rotates, causing the outer mold to flip to a certain extent. At this time, the three outer molds in the three outer mold components are completely separated from the casting.

[0005] Preferably, an automatic discharging device is fixed inside the base. The automatic discharging device includes a hydraulic telescopic rod. At the top of the hydraulic telescopic rod, a material pushing block is fixed. Three hydraulic chambers are communicated and fixed to the outside of the hydraulic telescopic rod. At one end of the three hydraulic chambers away from the hydraulic telescopic rod, a hydraulic rod is slidably connected. When the three vertical rods rotate simultaneously, they will synchronously squeeze the three hydraulic rods, causing the hydraulic telescopic rod to push the material pushing block upward to lift the casting on the cylindrical mold.

[0006] Preferably, a secondary ejector device is provided inside the ejector block. The secondary ejector device includes an ejector plate, an L-shaped rotating rod, and an L-shaped linkage rod. A rectangular groove is formed in the top plate of the ejector block. The ejector plate is elastically slidably connected inside the ejector block and is located in the rectangular groove through an elastic piece. The L-shaped rotating rod is rotatably connected inside the ejector block. The L-shaped linkage rod penetrates and is slidably connected inside the ejector block. The bottom of the L-shaped linkage rod is fixed inside the cylindrical mold. The left side of the L-shaped rotating rod is heavier than the right side. The horizontal plate of the L-shaped linkage rod is located above the right side of the L-shaped rotating rod. The left side of the L-shaped rotating rod is located below the ejector plate. When the ejector block moves upward for ejecting, the L-shaped linkage rod will squeeze the right side of the L-shaped rotating rod, causing the L-shaped rotating rod to rotate, thereby squeezing the ejector plate to move upward, making the casting that has been separated from the cylindrical mold rotate slightly, improving the convenience of the staff to take the material.

[0007] Preferably, a cooling device is fixed inside the three support rods. The cooling device includes a push-button switch type water pump. A soft rubber external pipeline is fixed at the water inlet of the push-button switch type water pump. An annular pipeline is fixed at the water outlet of the push-button switch type water pump. A plurality of soft glue water mist nozzles are fixed at the bottom of the annular pipeline. When the vertical rod rotates and unfolds, it will squeeze the push-button switch type water pump. At this time, water mist is sprayed through the soft glue water mist nozzles to cool the surface of the casting.

[0008] Preferably, a shaking device is provided on the annular pipeline. The shaking device includes a single-rail linear motor and an annular plate. The single-rail linear motor is fixed on the side of the push-button switch type water pump and is electrically connected to the push-button switch type water pump. The moving shaft of the single-rail linear motor is fixed to the annular plate, and a plurality of cylindrical rods are embedded inside the annular plate. Both the cylindrical rods and the soft glue water mist nozzles are provided with eight, and the eight cylindrical rods are respectively located directly above the eight soft glue water mist nozzles. While the push-button switch type water pump is working, the single-rail linear motor electrically connected to the push-button switch type water pump will push the annular plate to move up and down, causing the cylindrical rods to squeeze the soft glue water mist nozzles to swing, improving the spraying area of the water spray.

[0009] The present invention provides a precision casting automatic casting device. It has the following beneficial effects:

[0010] (1) By setting three movable outer mold components in the present invention, after the casting in this application is completed, the three movable outer mold components can be independently unfolded and moved through a multi-rail linear motor, and there will be no problem of material jamming.

[0011] (2) The present invention realizes the purpose of automatic ejection of the casting material located on the cylindrical mold by setting an automatic material ejection device, and controls the operation of the automatic material ejection device through the unfolding of the outer mold assembly, so as to achieve the purpose of interlocking material ejection, and can effectively eject the casting material automatically.

[0012] (3) The present invention sets a secondary material ejection device to perform secondary ejection on the already ejected casting material. The casting material ejected by the secondary material ejection device will be inclined to a certain extent, which is convenient for the staff to take.

[0013] (4) The present invention sets a cooling device to spray water mist on the surface of the casting material while the outer mold assembly unfolds, so as to achieve the purpose of rapid cooling and reduce the thermal radiation impact on the operator. Description of the Drawings

[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figure 1-7 , the present invention provides a technical solution: a precision casting automatic casting device, including a base 1. In the middle of the top of the base 1, a cylindrical mold 2 is fixed. On the outer side of the top of the base 1, three support rods 3 are fixed. At the top of the three support rods 3, a frustum 4 is fixed. At the top of the frustum 4, a multi-track linear motor 5 is fixed. An extendable feeding pipe 6 is embedded in the frustum 4. By setting the extendable feeding pipe 6, it is convenient to cast the combined mold as a whole. Three track grooves are opened on the frustum 4. At the top of the frustum 4, three blocking rods 10 are fixed, and the three blocking rods 10 are respectively located above the three track grooves. Three outer mold components 7 are arranged inside the frustum 4. The outer mold component 7 includes a slider 71. The slider 71 is slidably connected to the track groove of the frustum 4. The top of the slider 71 is connected to the moving shaft of the multi-track linear motor 5 through a connecting plate 72. A vertical rod 73 is rotatably connected inside the slider 71. At the bottom of the vertical rod 73, an outer mold 74 is fixed. After casting is completed, the multi-track linear motor 5 is started. The slider 71 is controlled to slide in the track groove through the connecting plate 72, so that the vertical rod 73 drives the outer mold 74 to move horizontally. Subsequently, after the vertical rod 73 is blocked by the blocking rod 10, it rotates, causing the outer mold 74 to flip to a certain extent. At this time, the three outer molds 74 in the three outer mold components 7 are completely separated from the casting.

[0024] Furthermore, an automatic discharging device 8 is fixed inside the base 1. The automatic discharging device 8 includes a hydraulic telescopic rod 81. At the top of the hydraulic telescopic rod 81, a material pushing block 82 is fixed. Three hydraulic chambers 83 are communicated and fixed to the outside of the hydraulic telescopic rod 81. At one end of the three hydraulic chambers 83 away from the hydraulic telescopic rod 81, a hydraulic rod 84 is slidably connected. When the three vertical rods 73 rotate simultaneously, they will synchronously squeeze the three hydraulic rods 84, so that the hydraulic telescopic rod 81 pushes the material pushing block 82 upward to lift the casting on the cylindrical mold 2.

[0025] Furthermore, a secondary ejector device 85 is provided inside the ejector block 82. The secondary ejector device 85 includes an ejector plate 851, an L-shaped rotating rod 852, and an L-shaped linkage rod 853. A rectangular groove is formed in the top plate of the ejector block 82. The ejector plate 851 is elastically slidably connected inside the ejector block 82 and is located within the rectangular groove. The L-shaped rotating rod 852 is rotatably connected inside the ejector block 82. The L-shaped linkage rod 853 penetrates and is slidably connected inside the ejector block 82. The bottom of the L-shaped linkage rod 853 is fixed inside the cylindrical mold 2. The weight on the left side of the L-shaped rotating rod 852 is greater than that on the right side. The horizontal plate of the L-shaped linkage rod 853 is located above the right side of the L-shaped rotating rod 852. The left side of the L-shaped rotating rod 852 is located below the ejector plate 851. When the ejector block 82 moves upward for ejecting, the L-shaped linkage rod 853 will squeeze the right side of the L-shaped rotating rod 852, causing the L-shaped rotating rod 852 to rotate, thereby squeezing the ejector plate 851 to move upward, making the casting that has been separated from the cylindrical mold 2 rotate slightly, improving the convenience of the staff for taking the material.

[0026] It should be noted that a cooling device 9 is fixed inside the three support rods 3. The cooling device 9 includes a push-button switch type water pump 91. A soft rubber external pipeline 92 is fixed to the water inlet of the push-button switch type water pump 91. An annular pipeline 93 is fixed to the water outlet of the push-button switch type water pump 91. A plurality of soft rubber water mist nozzles 94 are fixed to the bottom of the annular pipeline 93. While the vertical rod 73 rotates and unfolds, it will squeeze the push-button switch type water pump 91. At this time, water mist is sprayed through the soft rubber water mist nozzles 94 to cool the surface of the casting.

[0027] It should be noted that a shaking device 95 is provided on the annular pipeline 93. The shaking device 95 includes a single-rail linear motor 951 and an annular plate 952. The single-rail linear motor 951 is fixed to the side of the push-button switch type water pump 91 and is electrically connected to the push-button switch type water pump 91. The moving shaft of the single-rail linear motor 951 is fixed to the annular plate 952. A plurality of cylindrical rods 953 are embedded inside the annular plate 952. Both the cylindrical rods 953 and the soft rubber water mist nozzles 94 are provided with eight, and the eight cylindrical rods 953 are respectively located directly above the eight soft rubber water mist nozzles 94. While the push-button switch type water pump 91 is working, the single-rail linear motor 951 electrically connected to the push-button switch type water pump 91 will push the annular plate 952 to move up and down, causing the cylindrical rods 953 to squeeze the soft rubber water mist nozzles 94 to swing, improving the spraying area of the water spray.

[0028] In use, molten metal is fed between the outer mold 74 and the cylindrical mold 2 through the telescopic feeding pipe 6 for casting. After preliminary cooling and shaping, the multi-track linear motor 5 is started to control the synchronous operation of the three outer mold components 7 at the same time. The connecting plate 72 controls the slider 71 to slide in the track groove, so that the vertical rod 73 drives the outer mold 74 to move horizontally. Subsequently, after the vertical rod 73 is blocked by the blocking rod 10, it rotates, causing the outer mold 74 to turn to a certain extent. At this time, the three outer molds 74 in the three outer mold components 7 are completely separated from the casting. At the same time, when the three vertical rods 73 rotate simultaneously, they will simultaneously squeeze the three hydraulic rods 84, so that the liquid in the three hydraulic chambers 83 enters the hydraulic telescopic rod 81, and the hydraulic telescopic rod 81 pushes the ejector block 82 upward to lift the casting on the cylindrical mold 2. At the same time, when the ejector block 82 moves upward for ejecting, the L-shaped linkage rod 853 will squeeze the right side of the L-shaped rotating rod 852, causing the L-shaped rotating rod 852 to rotate, thereby squeezing the ejector plate 851 upward to make the casting that has been separated from the cylindrical mold 2 rotate slightly, improving the convenience of the staff to take the material;

[0029] While the vertical rod 73 rotates and unfolds, it will squeeze the push-button switch water pump 91. At this time, water mist is sprayed through the soft glue water mist nozzle 94 to cool the surface of the casting. While the push-button switch water pump 91 is working, the single-track linear motor 951 electrically connected to the push-button switch water pump 91 will push the annular plate 952 to move up and down, so that the cylindrical rod 953 squeezes the soft glue water mist nozzle 94 to swing, improving the spraying area of the water mist.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
