Description

Technical Field

[0001] The invention relates to the technical field of pump and valve production equipment, and in particular to a pump and valve casting rapid cooling casting device. Background Art

[0002] The pump and valve casting model is an auxiliary device used in the production and processing of pumps and valves to cast and shape the raw materials so that they can be better processed later. It has been widely used in the field of pump and valve production equipment technology. When the existing pump and valve casting model is used, the lower mold is fixed on the workbench, and the upper mold is driven up and down by the driving mechanism. After the mold is closed and the material is injected, the casting is cooled and formed.

[0003] After searching, the patent announcement number is: CN214236242U, a pump and valve casting model, first the lower mold is fixed on the fixed seat by bolts, then the upper mold is moved down to insert the sealing ring into the ring groove for sealing and closing the mold to form a sealed cavity, the raw material is introduced into the sealed cavity through the casting pipe, the external water source is connected through the water inlet pipe, and the cooling water is sprayed to the upper and lower molds through the ring pipe and the nozzle for rapid cooling.

[0004] Although the above patented technology can effectively spray cooling water onto the upper and lower molds to cool the casting, the above patent sprays water directly to cool down the casting mold when the surface of the casting mold is at high temperature, and cannot air-cool the casting mold in advance.

The upper end of the spiral tube 113 and the top of the two cylinder covers 9 are connected by a Y-shaped hose Ⅰ115.

[0036] See also Figure 6-Figure 9The driving mechanism includes two front and rear magnetic rods 81 connected to the upper right part of the outer wall of the inner cylinder 1, and a lifting arc-shaped iron plate 82 is slidably connected between the two magnetic rods 81. The front and rear rotating shafts 83 are rotatably connected to the arc-shaped iron plate 82. The two cylinder covers 9 are respectively connected to the top ends of the two rotating shafts 83. The two rotating shafts 83 are both provided with spiral grooves 84. The bottom right side of the inner cylinder 1 is slidably connected to a rod frame 85 that can be lifted and lowered. The rod frame 85 includes a vertical rod, an L-shaped lifting rod, an L-shaped connecting rod and a ring. The vertical rod is slidably connected to the bottom right side of the inner cylinder 1. The bottom end of the vertical rod is connected to the L-shaped lifting rod. The upper part of the L-shaped lifting rod is connected to the front and rear L-shaped connecting rods. The two L-shaped connecting rods are both connected with rings. The two rings are respectively slidably sleeved on the two rotating shafts 83. , the vertical rod and L-shaped lifting rod of the rod frame 85 are both sleeved with spring Ⅰ86, and the two ends of spring Ⅰ86 are respectively connected to the bottom of the L-shaped lifting rod and the bottom of the inner tube 1, and the two rings on the rod frame 85 are rotatably connected with balls 87, and the two balls 87 are respectively located in the spiral grooves 84 on the two rotating shafts 83. The L-shaped lifting rod on the rod frame 85 is slidably sleeved with a guide sleeve, which is fixedly connected to the right side of the outer wall of the water cylinder 2. The L-shaped lifting rod can be guided by the guide sleeve to ensure that the entire rod frame 85 is lifted and lowered smoothly. The lifting frame 4 moves downward to contact the vertical rod on the rod frame 85 and push the vertical rod downward. The upper part of the outer wall of the inner tube 1 is connected to a sealing ring 88 located on the upper side of the magnetic rod 81, and the top of the sealing ring 88 is provided with a receiving groove 89 for accommodating the cylinder cover 9.

[0037] Initially, the rod frame 85 is pressed down by the lifting frame 4, the spring I86 is in a stretched state, and the two cylinder covers 9 are inserted into the receiving groove 89 on the sealing ring 88 to seal the inner cylinder 1. The lifting mechanism is controlled to drive the upper mold 7 to move down to complete the mold closing action. Then, the injection pipe on the lower mold 5 is connected to the external feeding equipment to inject the high-temperature molten raw materials between the upper mold 7 and the lower mold 5. Then, the driving motor 105 is controlled to drive the fan blade 106 to rotate. The fan blade 106 rotates to generate wind force, which is transported to the annular nozzle 101 through the conveying hose 1010. The annular nozzle 101 then sprays the airflow to the lower mold 5 and the upper mold 7, so as to achieve pre-cooling of the lower mold 5 and the upper mold 7. At the same time, the control drive part Ⅱ102 drives the annular nozzle 101 to move up and down reciprocatingly, so as to spray the airflow evenly to the lower mold 5 and the upper mold 7, thereby increasing the cooling area; when the temperature sensor 1011 detects that the temperature of the lower mold 5 and the upper mold 7 drops below the set first preset value, the temperature sensor 1011 sends a signal to the controller (the controller is not shown in the figure, the controller is prior art, and is not described here), and the controller then sends an instruction to open the solenoid valve 108, so that the cooling water in the cavity 21 of the water cylinder 2 flows into the pipe 107, and continuously replenishes the cooling water into the cavity 21 of the water cylinder 2. The driving motor 105 drives the screw conveying shaft 109 to rotate and convey the cooling water in the pipe 107 upward. The cooling water enters the annular nozzle 101 through the conveying hose 1010 and is sprayed on the lower mold 5 and the upper mold 7 by the annular nozzle 101 to realize water cooling of the lower mold 5 and the upper mold 7. The cooling water can be discharged from the inner cylinder 1 to a suitable place by connecting the external pipe of the drain pipe at the bottom of the inner cylinder 1 to recycle the cooling water. When the temperature sensor 1011 detects that the temperature of the lower mold 5 and the upper mold 7 drops below the set second preset value, the temperature sensor 1011 sends a signal to the controller again, and the controller controls the solenoid valve 108 to close and stop supplying liquid to the annular nozzle 101, so that the annular nozzle 101 only sprays airflow, thereby blowing away the cooling water remaining on the outer surface of the lower mold 5 and the upper mold 7. In this way, the device can supply external air to pre-cool the lower mold 5 and the upper mold 7 when the temperature of the lower mold 5 and the upper mold 7 is too high, and supply cooling water to cool the lower mold 5 and the upper mold 7 after the temperature of the lower mold 5 and the upper mold 7 drops to a certain level. This can not only ensure the safety and efficiency of cooling, but also reduce the risk of cracking or deformation of the casting due to excessive cooling speed.

[0038] Since the inner cylinder 1 is sealed by the cylinder cover 9, the high-temperature water vapor generated when the lower mold 5 and the upper mold 7 are water-cooled will not diffuse outward into the surrounding environment, thereby preventing air pollution and reducing the risk of scalding of the staff. The high-temperature water vapor rises and enters the Y-shaped hose Ⅰ115, and the high-temperature water vapor is introduced into the spiral tube 113 through the Y-shaped hose Ⅰ115, so that the high-temperature water vapor is cooled by the cooling water in the cavity 21. The spiral tube 113 can extend the flow path of the high-temperature water vapor in the cavity 21, thereby extending the time for the high-temperature water vapor to be cooled by the cooling water, so as to improve the cooling effect of the high-temperature water vapor. After being cooled, the high-temperature water vapor is liquefied into water, and the water pump Ⅰ111 is controlled to work, and the liquefied water is transported back to the cavity 21 through the infusion pipe Ⅰ112 and the infusion pipe Ⅱ114, realizing the recycling of water in the high-temperature water vapor and reducing the waste of water resources. The remaining gas after cooling is discharged outward through the top of the infusion pipe Ⅰ112. In this way, the inner cylinder 1 can be sealed by the cylinder cover 9, and the high-temperature water vapor can be effectively prevented from escaping, so as to avoid the high-temperature water vapor from diffusing outward to the surrounding environment to cause pollution, and the risk of scalding of the staff can be reduced. The combination of the Y-shaped hose Ⅰ115 and the spiral tube 113 can effectively guide the high-temperature water vapor into the cavity 21 for cooling, so that the high-temperature water vapor can be liquefied into water. Through the coordinated work of the water pump Ⅰ111, the infusion tube Ⅰ112 and the infusion tube Ⅱ114, the water can be transported back to the cavity 21, so as to achieve the effect of recycling the moisture in the high-temperature water vapor, thereby reducing the waste of water resources and achieving the purpose of saving water resources.

[0039] After the casting is cooled and completely formed, the driving member Ⅰ3 is controlled to drive the lifting frame 4 to move up and disengage from the rod frame 85. Under the reset action of the spring Ⅰ86, the rod frame 85 is pushed to move up with the ball 87. Since the cylinder cover 9 is inserted in the accommodating groove 89 of the sealing ring 88 at this time, the cylinder cover 9 cannot be directly rotated to open. Then, as the ball 87 moves up, the rotating shaft 83 is pushed up, and the upward movement of the rotating shaft 83 drives the arc-shaped iron plate 82 and the cylinder cover 9 to move up. When the cylinder cover 9 moves up and disengages from the sealing ring 88, the cylinder cover 9 can rotate freely. Due to the magnetic attraction of the magnetic rod 81 to the arc-shaped iron plate 82, when the cylinder cover 9 is separated from the sealing ring 88, the arc-shaped iron plate 82 will not continue to move upward, and the cylinder cover 9 will not continue to move upward. At this time, the ball 87 continues to move upward and cooperates with the spiral groove 84, prompting the cylinder cover 9 to rotate and open, avoiding obstruction of the subsequent lower mold 5 and upper mold 7 from moving upward from the inner cylinder 1, so that the lower mold 5 and upper mold 7 can be moved upward from the inner cylinder 1 to facilitate the removal of the casting. After the casting is taken out, the control driving member I3 drives the lifting frame 4 to move downward, thereby driving the lower mold 5 and upper mold 7 to move downward into the inner cylinder 1. When the lifting frame 4 moves down to contact the rod frame 85, the lifting frame 4 pushes the rod frame 85 to drive the ball 87 to move downward, and the spring I86 is stretched accordingly. The ball 87 moves downward and cooperates with the spiral groove 84, prompting the cylinder cover 9 to reverse and close. After the two cylinder covers 9 are closed, they are in contact with each other and cannot be reversed further, and at this time, the ball 87 has moved down to the bottom of the spiral groove 84, so that the ball 87 continues to move down to push the shaft 83 to move down, and the shaft 83 moves down to drive the arc iron plate 82 and the cylinder cover 9 to move down, until the cylinder cover 9 is inserted back into the receiving groove 89 on the sealing ring 88, completing the sealing of the inner cylinder 1. In this way, the device can automatically drive the cylinder cover 9 to rotate and open while the lifting frame 4 drives the lower mold 5 and the upper mold 7 to move upward out of the inner cylinder 1, and can automatically drive the cylinder cover 9 to close while the lifting frame 4 drives the lower mold 5 and the upper mold 7 to move downward into the inner cylinder 1. The whole process does not require manual opening and closing of the cylinder cover 9, which can save time and effort.

[0040] See also Figure 10-11The cylinder cover 9 is provided with a liquid guiding mechanism for guiding the liquid into the cavity 21. The liquid guiding mechanism includes five condensation plates 121 connected to the top of the inner side of the cylinder cover 9 at even intervals from front to back. The condensation plate 121 on the front cylinder cover 9 is installed with a low front and a high back and an inclined installation. The condensation plate 121 on the rear cylinder cover 9 is installed with a high front and a low back and an inclined installation. The inner wall of the cylinder cover 9 is connected with a guide groove 123 located at the lower side of the condensation plate 121. The guide groove 123 is in an arc shape. The lower part of the condensation plate 121 is connected with a guide groove 123 for guiding the liquid. To the guide plate 122 in the guide groove 123, and the condensation plate 121 and the guide plate 122 are both installed at an angle with the left side higher and the right side lower, so as to smoothly guide the liquid into the guide groove 123, and the sides of the two guide grooves 123 close to each other are connected with a return hose 124, and the bottom end of the return hose 124 extends into the cavity 21, and the two guide grooves 123 are installed at an angle, and the sides of the two guide grooves 123 close to each other are lower than the sides of the two guide grooves 123 away from each other, so as to guide the liquid to the return hose 124.

[0041] After the high-temperature water vapor rises and contacts the condensation plate 121, it is cooled and liquefied into water. Through the cooperation of the condensation plate 121 and the guide plate 122, the liquefied water is directed to the guide groove 123, and the guide groove 123 then directs the water to the return hose 124, and the water is returned to the cavity 21 through the return hose 124. In this way, it can reduce the situation where the water vapor condenses at the top of the inner side of the cylinder cover 9 and gathers into drops and falls back on the lower mold 5 and the upper mold 7. At the same time, the condensation plate 121 can catch the water drops dripping from the top of the inner side of the cylinder cover 9, and prevent these water drops from mixing into the casting space between the lower mold 5 and the upper mold 7, thereby preventing the casting from having holes, cracks and other problems during the molding process, and can also prevent water drops from falling on the ground around the device and the outer walls of the inner cylinder 1 and the water cylinder 2 during the opening of the cylinder cover 9, thereby further reducing the waste of water resources.

[0042] See also Figure 10-11 A liquid circulation mechanism is provided between the water cylinder 2 and the condensation plate 121, and the liquid circulation mechanism includes a water pump Ⅱ131 installed on the right side of the outer wall of the water cylinder 2, and a delivery pipe 132 is connected to the input end and the output end of the water pump Ⅱ131, and a Y-shaped hose Ⅱ133 is connected to the delivery pipe 132 at the output end of the water pump Ⅱ131, and the front and rear ends of the Y-shaped hose Ⅱ133 are respectively extended into the two cylinder covers 9, and the front and rear ends of the Y-shaped hose Ⅱ133 respectively pass through the condensation plates 121 on the two cylinder covers 9, and a Y-shaped hose Ⅲ134 is connected between the front and rear ends of the Y-shaped hose Ⅱ133, and the bottom end of the Y-shaped hose Ⅲ134 extends into the cavity 21.

[0043] Control the operation of water pump II 131 to input the cooling water in cavity 21 into Y-shaped hose II 133 through delivery pipe 132. The cooling water absorbs the heat on condensation plate 121, thereby cooling down condensation plate 121 to improve the condensation efficiency and effect of condensation plate 121 on high-temperature water vapor. The cooling water in Y-shaped hose II 133 then flows back to cavity 21 through Y-shaped hose III 134, forming a circulation of cooling water.

[0044] See also Fig.12 The bottom of the lower mold 5 and the top of the upper mold 7 are both equipped with metal heat dissipation fins 14, which are made of copper with good thermal conductivity. The heat on the surface of the lower mold 5 and the upper mold 7 can be quickly discharged outward through the metal heat dissipation fins 14, so that the heat can effectively contact the cooling water to quickly reduce the temperature of the surface of the lower mold 5 and the upper mold 7, thereby achieving a uniform and rapid cooling effect.

[0045] See also Figure 4 A slide groove is opened on the left side of the inner wall of the inner tube 1, and a lifting connecting rod 15 is slidably connected in the slide groove. A support wheel 16 for supporting the delivery hose 1010 is rotatably connected to the connecting rod 15. A spring II 17 is connected between the bottom of the connecting rod 15 and the inner bottom of the slide groove. The connecting rod 15 can be supported by the spring II 17 to prevent the connecting rod 15 from driving the support wheel 16 to move down and separate from the delivery hose 1010. The support wheel 16 can support and guide the delivery hose 1010 so that the delivery hose 1010 is always kept in a taut state to prevent the delivery hose 1010 from being entangled and knotted when it is raised or lowered, thereby ensuring that the delivery hose 1010 remains unobstructed to stably deliver airflow and cooling water.
