[0001] The present invention relates to the technical field of casting molding equipment, and more specifically to a casting molding device. Background Art

[0002] Casting is a manufacturing method that pours molten metal or other materials into a mold of a specific shape, allowing it to cool and solidify into a workpiece with a predetermined shape and size. The casting process plays an extremely important role in industrial production. This process can be used to produce a variety of items, from small metal parts to large mechanical components, and even artworks and decorations. Casting is a very important part of the manufacturing industry and is widely used in the fields of automobile manufacturing, aerospace, construction, etc., and a molding device is required for casting;

[0003] However, the existing casting molding devices have poor cooling effect during actual use and require a lot of time for cooling, which affects the working efficiency of the casting molding. In addition, during the casting molding, the molten metal will come into contact with the air, which may produce some metal mist or aerosol. These particles will also form dust, which poses a certain threat to the health of the workers. In addition, due to the casting method or the structure of the casting, bubbles are easily generated inside the casting, which causes quality problems in the molded product. Summary of the invention

[0006] The smoke purification box is beneficial for the molten metal used in casting to enter the lower mold shell and the upper mold shell and come into contact with the internal air. The metal mist and aerosol or dust generated by the contact between the molten metal and the air is introduced into the smoke purification box through the first hose, so that the smoke purification box can filter and purify the generated metal mist and dust, thereby avoiding harm caused by inhalation of toxic mist and dust by workers, thereby achieving the effect of protecting workers and the working environment.

A rotating head is fixedly connected to the surface of the telescopic rod near the bottom. The circular air plug and the telescopic rod can help to block the generated gas and air when the molten metal enters the mold, so that the compressed air pushes the circular air plug, and the circular air plug drives the telescopic rod to move up and down, thereby making full use of the generated gas.

[0008] In a preferred embodiment, a circular hole is provided at the top of the purification core, a filter screen is provided inside the purification core, and neatly arranged activated carbon spheres are provided at the upper and lower ends of the filter screen inside the purification core.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention is provided with a cooling inner cavity and an external spray rack, which is conducive to the flow of coolant in the cooling inner cavity during casting, so that the temperature inside the mold is quickly replaced, and when the coolant is sprayed through the external spray rack, the temperature inside the coolant is replaced with the cold air in the air, thereby ensuring that the coolant always maintains a certain low temperature, so that the cooling effect of the coolant remains unchanged, and then the casting inside the mold is quickly cooled, so that the cooling effect is enhanced, and the working efficiency of casting is increased;

[0016] 2. The present invention is provided with a smoke and dust purification box, which is conducive to introducing metal mist and aerosol or wind dust generated by the contact between the molten metal and the air into the smoke and dust purification box through the first hose when the molten metal for casting enters the lower mold shell and the upper mold shell and contacts the air inside, so that the purification core inside the smoke and dust purification box is filtered and purified by the activated carbon sphere and the filter net, thereby preventing the toxic mist and wind dust from being inhaled by the workers and causing harm;

[0017] 3. The present invention is provided with a circular air plug, a telescopic rod, a reset spring, a rotating head and a sliding plate. When the smoke purification box filters and purifies metal mist and wind dust, the hot air pushes the circular air plug and the telescopic rod to squeeze the reset spring, so that the telescopic rod drives the rotating head to squeeze inside the sliding plate. At this time, the sliding plate slides on the top of the fixed block due to the extrusion, so that the sliding plate pushes the lower mold shell, and when the circular air plug reaches the circular exhaust hole, as the gas discharge pressure decreases, the reset spring drives the circular air plug and the telescopic rod to reset, so that the sliding plate pulls the lower mold shell, so that the lower mold shell shakes left and right, and then the molten metal liquid inside the lower mold shell shakes, thereby preventing the formation of bubbles inside after casting, thereby increasing the quality of the product after molding.

[0031] In this embodiment: the circular air plug 16 and the telescopic rod 17 are used to block the gas and air generated when the molten metal enters the mold, so that the compressed air pushes the circular air plug 16, and the circular air plug 16 drives the telescopic rod 17 to move up and down, so that the gas generated by it can be fully utilized.

[0032] Reference Figure 3 As shown, a circular hole 1501 is provided at the top of the purification core 15 , a filter screen 1502 is provided inside the purification core 15 , and neatly arranged activated carbon spheres 1503 are provided at the upper and lower ends of the filter screen 1502 inside the purification core 15 .

[0033] In this embodiment: by purifying the filter net 1502 and the activated carbon sphere 1503 inside the inner core 15, it is beneficial to filter and purify the dust and metal mist generated by the contact between the metal liquid and the air, so that the toxic and harmful substances contained in the metal mist can be absorbed, and the toxic mist and dust inside the mist can be avoided from being directly discharged to the outside, thereby preventing air pollution and affecting the health of the workers.

[0035] In this embodiment, the rotating wheel 1902 and the limiting piece 1903 facilitate the rotating wheel 1902 to rotate inside the sliding plate 20 when the telescopic rod 17 is extended and retracted up and down, so that the sliding plate 20 slides due to the extension and retraction of the telescopic rod 17 .

[0036] Reference Figure 5 As shown, a rectangular slide groove 601 is provided at the top of the fixed block 6, a sliding plate 20 is movably connected inside the rectangular slide groove 601, a rectangular slide rail 2002 is provided at the bottom of the sliding plate 20, a special-shaped slide groove 2001 is provided inside the sliding plate 20, and a push rod 2003 is fixedly connected to the side surface of the sliding plate 20 close to the lower mold shell 3.

[0037] In this embodiment, the rectangular slide rail 2002 and the special-shaped slide groove 2001 opened by the sliding plate 20 are conducive to limiting the position of the sliding plate 20 through the rectangular slide rail 2002, so that when the rotating head 19 moves inside the special-shaped slide groove 2001, it drives the sliding plate 20 to slide back and forth.

[0039] In this embodiment: through the boost pump 21, the second hose 14, and the third hose 1401, the operation of the boost pump 21 is conducive to driving the coolant inside the coolant storage tank 5 to flow inside the second hose 14 and the third hose 1401, so that the temperature inside the mold is replaced and cooled, achieving the effect of rapid cooling.

[0040] Reference Figure 7 As shown, a circular through hole 1102 is provided at the top of the upper mold shell 11 at the position fixedly connected to the first hose 10, connecting rods 1101 are provided at the four corners of the bottom of the upper mold shell 11, and neatly arranged spray heads 1201 are provided at the bottom of the external spray rack 12. A lifting plate 22 is fixedly connected to one side of the surface of the upper mold shell 11, and telescopic columns 23 are fixedly connected to both sides of the bottom of the lifting plate 22, and cylinders 24 are provided at the bottom of the telescopic columns 23.

[0041] In this embodiment, the lifting plate 22, the telescopic column 23 and the cylinder 24 are used to drive the upper mold shell 11 to move up and down, so as to facilitate the removal of the product after casting inside the mold.

[0042] Reference Figure 8 As shown, circular connecting holes 301 are provided at the four corners of the top of the lower mold shell 3, a cooling inner cavity 302 is provided around the inner periphery of the outer wall of the lower mold shell 3, a rectangular groove 401 is provided inside the coolant reflux rack 4, and neatly arranged vibration springs 25 are fixedly connected at both sides of the surface of the rectangular movable plate 2.

[0043] In this embodiment: the vibration spring 25 is used to increase the shaking force of the lower mold shell 3 when the lower mold shell 3 is pushed, thereby causing the molten metal inside to shake, thereby eliminating bubbles inside the cast product and increasing the quality after casting.

[0044] The working principle of the present invention is as follows: first, when in use, the cylinder 24 on the top of the rectangular movable plate 2 is opened, so that the cylinder 24 drives the telescopic column 23 to extend and retract, and then the telescopic column 23 drives the lifting plate 22 and the upper mold shell 11 to approach the top of the lower mold shell 3 when it is extended and retracted, so that the connecting rod 1101 at the bottom of the upper mold shell 11 enters the circular connecting hole 301 opened on the top of the lower mold shell 3, so that the lower mold shell 3 and the upper mold shell 11 are closed and connected, and then the molten metal liquid is injected through the feeding pipe 13, and then when the metal liquid enters the lower mold shell 3 and the upper mold shell 11, the air inside the lower mold shell 3 and the upper mold shell 11 contacts the metal liquid and generates metal mist and dust. At the same time, the air inside the lower mold shell 3 and the upper mold shell 11 is squeezed out through the circular through hole 1102 opened in the upper mold shell 11 after the metal liquid is injected, and then the air inside the circular through hole 1102 and the high-temperature metal mist and dust enter the purification inner core 15 that is movably connected inside the smoke purification box 9 through the first hose 10, and then the high-temperature metal mist, dust and air enter the purification inner core 15 through the circular hole 1501, and the activated carbon spheres 1503 on the upper and lower surfaces of the filter 1502 filter and absorb the harmful gases in the metal mist, and then the dust is blocked by the filter 1502, so that the relatively clean high-temperature mist and air enter the cylindrical inner cavity 901. At this time, as the molten metal is injected into the lower mold The inside of the tool shell 3 and the upper mold shell 11 causes the high-temperature gas and air in the cylindrical inner cavity 901 to increase. At this time, the circular air plug 16 inside the cylindrical inner cavity 901 is squeezed to drive the telescopic rod 17 to descend, and the reset spring 18 is squeezed when the circular air plug 16 descends. At this time, the telescopic rod 17 reaches the rotating head 19 when it descends and descends. Then, the rotating wheel 1902 on the surface of the connecting shaft 1901 rotates inside the special-shaped slide groove 2001 opened on the sliding plate 20 under the restriction of the limit plate 1903, and with the downward pressure of the rotating head 19, the rectangular slide rail 2002 opened on the sliding plate 20 slides inside the rectangular slide groove 601 opened on the fixed block 6. At this time, the sliding of the sliding plate 20 drives the push rod 2003 to move the rectangular movable The lower mold shell 3 on the top of the plate 2 is pushed, and then the lower mold shell 3 and the upper mold shell 11 are shaken with the assistance of the vibration springs 25 on both sides of the rectangular movable plate 2. Then, when the circular air plug 16 reaches the circular exhaust hole 902 opened in the smoke purification box 9, the gas discharge pressure inside the cylindrical inner cavity 901 is reduced. Then the reset spring 18 pushes the circular air plug 16 and the telescopic rod 17 to rise. Then the rise of the telescopic rod 17 causes the rotating head 19 to drive the sliding plate 20 to reset and slide, and the lower mold shell 3 is pulled to the other side. Then, due to the injection of molten metal, the circular air plug 16 installed as described above is driven to perform repeated telescopic movements, and then the sliding plate 20 drives the lower mold shell 3 to shake horizontally.As a result, the molten metal inside the lower mold shell 3 is more tightly packed due to the shaking, and bubbles are avoided after the casting. Then, after the molten metal is injected, the gas stops entering the smoke purification box 9, and then the sliding plate 20 stops pushing the lower mold shell 3 to shake. At this time, the booster pump 21 is turned on, so that the booster pump 21 drives the coolant inside the coolant storage box 5 to enter the external spray rack 12 and the cooling inner cavity 302 through the second hose 14 and the third hose 1401 respectively, and then the external spray rack 12 sprays the coolant to the upper mold shell 11 through the spray head 1201. The surface of the cooling liquid is sprayed, and enters the rectangular groove 401 opened in the cooling liquid reflux rack 4 through the surface of the lower mold shell 3. Then, the cooling liquid in the cooling cavity 302 is mixed with the cooling liquid in the rectangular groove 401 after circulation, and flows back to the cooling liquid storage tank 5 driven by the booster pump 21. Then, the sprayed cooling liquid is cooled by air to reduce the temperature of the mixed cooling liquid in the cooling liquid storage tank 5, so that the temperature of the cooling liquid in the cooling cavity 302 will be reduced, thereby keeping the cooling speed consistent and preventing the cooling liquid temperature from being too high and reducing the cooling speed.

[0045] Finally: The above description is only a preferred embodiment of the present invention and is 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.
