[0020] The present invention provides a nozzle and a casting device for pouring water. Compared with the prior art, it has the following beneficial effects:

[0021] (1) The oil nozzle and casting equipment thereof, which are convenient for pouring water flow, are provided with an oil nozzle body, an interface, a sealing box, a piston plate, a fixing rod, a second spring, a supporting rod, and a baffle. An interface is added to the side wall of the oil nozzle body, and a sealing box is installed on the interface. The oil nozzle body is installed on a large-capacity oil barrel or oil tank. In the process of pouring the lubricating oil in the oil barrel or oil tank into a small-capacity container, the lubricating oil will impact on the baffle, causing the air pressure in the inner cavity of the sealing box to change, so that the gas is mixed into the lubricating oil that has entered the oil nozzle body, thereby occupying the space of the lubricating oil in the oil nozzle body. At the same time, the gas enters the large-capacity container to reduce the pressure difference between the inside and outside of the container, so that when the lubricating oil flows out of the oil nozzle body, a large number of bubbles will not appear in the lubricating oil due to the excessive pressure difference between the inside and outside, causing the water flow to stop or stop periodically, thereby accelerating the speed of transferring the lubricating oil from the large-capacity container to the small-capacity container.

[0022] (2) The oil nozzle and its casting equipment for easy pouring of water flow are provided with a die-casting unit, a movable part, a fixed part, a molding groove, a hydraulic rod, a fixed plate, a support column, an upper molding block, a push block, a magnet 1, a magnet 2, a support plate, a side plate, a driven rod, a lower molding block, a connecting plate, a magnet 3, a sliding rod, an upper slider, a lower slider, a mounting plate, a limit block, a power rod, a piston ring, an auxiliary slider, a limit rod, a spring 1, a positioning plate, a sealing plate, a metal plate, an air pipe, and a vacuum pump. The strength of the oil nozzle body is enhanced by die-casting the oil nozzle body and the interface into one piece, and there is no need to weld the interface to the oil nozzle body after the oil nozzle body is die-cast. This can not only reduce the processing procedures, save processing time and thus improve processing efficiency, but also avoid the phenomenon of desoldering and liquid leakage at the welding position after long-term use, thereby extending the service life of the oil nozzle body. At the same time, it can also improve the sealing of the enclosed space used for molding, effectively reduce the air content in the sealed space, reduce the bubble content in the oil nozzle body after molding, and improve the strength of the oil nozzle body.

[0023] (3) The oil nozzle and its casting and pressing equipment that are convenient for pouring water flow are provided with a pull handle, a push rod, and a metal sheet. By starting the vacuum pump and pulling the pull handle, the metal sheet is moved to the right side of the upper molding block, and then the upper molding block is inserted into the lower molding block. At the same time, the pull handle is pulled to move the metal sheet to the side where the hydraulic rod is located, so that the metal sheet is sucked tightly on the inner wall of the molding groove away from the side wall. At this time, the enclosed space used for molding is between the left side of the metal sheet and the right side of the sealing plate, which further improves the vacuum level in the enclosed space, reduces the bubble content in the oil nozzle body after molding, and improves the strength of the oil nozzle body.

[0024] (4) The oil nozzle and its casting equipment for easy pouring of water flow are designed by setting the upper wall and side wall of the oil nozzle at 84 degrees, the upper wall and lower wall at 54 degrees, and the lower wall groove at an angle of 81 degrees. By modifying the water outlet angle of the oil nozzle shape, the centripetal force of the water flow adhering to the wall is increased, so that the water flow falls vertically and flows out cleanly. The waterproof backflow groove design prevents oil from dripping and flowing back on the outer side wall of the pot body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in 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.

[0042] See also Figures 1 to 15 , the present invention provides the following technical solutions:

[0043] When used for industrial purposes, the nozzle body 1 can be installed on a large-capacity oil barrel or oil tank to control the pouring speed of lubricating oil, engine oil or other industrial oils into a small-capacity container. However, when the current nozzle body 1 is in use, there will be a pressure difference between the oil barrel or oil tank of the large container and the pressure of the outside world, which will easily cause a large number of bubbles to appear at the nozzle body 1 during the pouring and transfer process and move into the large-capacity container, causing the water flow to periodically stop or stop. This makes it easy for the lubricating oil to spill outside the small-capacity container during the pouring and transfer process, resulting in waste.

[0044] Embodiment 1: A nozzle for pouring water is made by die-casting using a casting and pressing device, comprising a nozzle body 1 and an interface 11. The nozzle body 1 and the interface 11 are connected, one end of the interface 11 is connected to a closed box 12 through an outlet valve, the closed box 12 is divided into two inner chambers, a piston plate 13 is slidably connected to the inner wall of the inner chamber one, the inner chamber two is connected to the interface 11, a fixing rod 14 is fixedly installed on the top of the piston plate 13, one end of the fixing rod 14 is slidably penetrated in the closed box 12 and passes out from the top of the closed box 12, a supporting rod 16 is fixedly installed on one end of the fixing rod 14, a baffle 17 is fixedly installed on one end of the supporting rod 16, the baffle 17 is located at the oil outlet of the nozzle body 1, a spring 2 15 is fixedly installed on one end of the supporting rod 16, the other end of the spring 2 15 is fixedly installed on the side wall of the closed box 12, and the spring 2 15 is sleeved outside the fixing rod 14.

[0045] When in use, an interface 11 is added to the side wall of the nozzle body 1, and a sealed box 12 is installed on the interface 11, and the nozzle body 1 is installed on a large-capacity oil barrel or oil tank. In the process of pouring the lubricating oil in the oil barrel or oil tank into a small-capacity container, the lubricating oil will flow out from the oil outlet and impact on the baffle 17, causing the baffle 17 to move away from the nozzle body 1. The baffle 17 drives the support rod 16 to move synchronously, the support rod 16 drives the fixing rod 14 to move, and the fixing rod 14 drives the piston plate 13 to move. The air pressure in the inner cavity 1 of the sealed box 12 is changed by the piston plate 13, so that the air outside the sealed box 12 enters the inner cavity 1 from the one-way air inlet valve on the side wall. At this time, since the baffle 17 is far away from the oil outlet of the nozzle body 1, the impact force it receives becomes smaller, so that the baffle 17, the support rod 16, and the piston plate 13 are reset to the initial position again under the pulling force of the spring 15 until they move to the position as shown in the figure. Figure 3 In the position shown, during the movement, the piston plate 13 will transport the gas in the inner cavity 1 to the inner cavity 2 through the one-way air outlet valve, and inject it into the nozzle body 1 through the interface 11 and the air outlet valve, so that the gas is mixed with the lubricating oil that has entered the nozzle body 1, thereby occupying the space of the lubricating oil in the nozzle body 1, and at the same time, the gas enters the large-capacity container to reduce the pressure difference between the inside and outside of the container;

[0046] When the baffle 17 approaches the oil outlet of the nozzle body 1 again under the pulling force of the spring 2 15, the impact force of the lubricating oil on the baffle 17 will increase again, thereby repeating the process of injecting gas into the nozzle body 1. When the lubricating oil flowing out of the nozzle body 1 presents a continuous and stable water flow, the baffle 17 will only continue to move to the side away from the nozzle body 1 under the impact of the lubricating oil. Once the water flow changes, the piston plate 13 can also respond immediately to inject air into the nozzle body 1.

[0047] The gas is mixed into the lubricating oil that has entered the nozzle body 1, thereby occupying the space of the lubricating oil in the nozzle body 1. At the same time, the gas enters the large-capacity container to reduce the pressure difference between the inside and outside of the container. When the lubricating oil flows out of the nozzle body 1, there will be no large number of bubbles in the lubricating oil that continue to float up due to the excessive pressure difference between the inside and outside, causing the water flow to periodically stop or stop.

[0050] When in use, by starting the hydraulic rod 2, the hydraulic rod 2 drives the fixed plate 21 to move downward, the fixed plate 21 drives the support column 22 to move downward, the support column 22 drives the upper forming block 23 to move, and at the same time, the fixed plate 21 drives the push block 24 to move downward, the push block 24 drives the magnet 1 25 to move downward, the magnet 1 25 and the magnet 2 26 are magnetically attracted to each other, so that the magnet 2 26 drives the support plate 27 to move downward, and the contacting side between the support plate 27 and the push block 24, the magnet 1 25 and the magnet 2 26 are all inclined, so that the support plate 27 moves downward. During the process, the side plate 28 is driven to approach the side where the movable part 102 is located, the side plate 28 drives the driven rod 29 to move, the driven rod 29 drives the lower forming block 210 to move, and the lower forming block 210 and the movable part 102 slide and cooperate with each other until the side plate 28 and the side wall of the movable part 102 are abutted together. At this time, the magnet 1 25 and the magnet 2 26 are separated under the drive of the hydraulic rod 2, and the lower forming block 210 is located in the forming groove and the end of the lower forming block 210 away from the driven rod 29 is pressed against the inner wall of the forming groove 104.

[0051] At this time, the hydraulic rod 2 continues to descend and only drives the support column 22 and the upper forming block 23 to move through the fixed plate 21, so that the upper forming block 23 can be stuck in the lower forming block 210, and then the movable part 102 is controlled to move to the side where the fixed part 103 is located, so that the fixed part 103 and the movable part 102 are combined together, and the metal liquid is pressed into the forming groove 104 on the fixed part 103 and the movable part 102 after they are combined, and then cooled and formed to obtain the nozzle body 1;

[0052] The movable part 102 is controlled to move away from the fixed part 103, so that the fixed part 103 and the movable part 102 are separated, and then the hydraulic rod 2 is started to drive the fixed plate 21 to move upward, so that the fixed plate 21 first drives the upper forming block 23 to move out of the lower forming block 210 through the support column 22.

This not only reduces the processing steps and saves processing time, thereby improving processing efficiency, but also avoids desoldering and leakage at the welding position after long-term use, thereby extending the service life of the nozzle body 1.

An auxiliary slider 39 is slidably installed in the lower forming block 210, and a limit rod 310 is fixedly installed on the side wall of the auxiliary slider 39.

The other end of the spring 311 is fixedly installed on the side wall of the auxiliary slider 39, and one end of the positioning plate 312 is fixedly installed on the sealing plate 313. One end of the sealing plate 313 abuts against the forming groove 104 to isolate the forming groove 104 from the air exchange with the outside, and the side wall of the sealing plate 313 slides against the lower forming block 210, and one end of the upper forming block 23 abuts against the lower forming block 210;

[0056] A metal plate 314 is abutted inside the lower forming block 210 , and the top of the metal plate 314 abuts against the bottom of the upper forming block 23 ;

The sealing plate 313 and the auxiliary slider 39 are both made of metal materials and have a certain elasticity. In the process of extending out of the lower forming block 210, they can be deformed appropriately, so that one end of the sealing plate 313 is tightly against the inner wall of one side of the forming groove 104, so that a closed space is formed between the forming groove 104 and the movable part 102;

[0059] At the same time, a metal plate 314 is placed in the lower forming block 210. The metal plate 314 is made of memory metal material. When the upper forming block 23 is inserted into the lower forming block 210, the upper forming block 23 will squeeze the metal plate 314 to deform it, thereby filling the gap between the lower forming block 210 and the upper forming block 23 and exceeding it by a small part.

The side wall of the metal sheet 42 is abutted and installed in the installation groove provided on the lower forming block 210. Two push rods 41 are adhered to the side wall of the metal sheet 42. One end of the two push rods 41 are slidably inserted into the movable portion 102, and one end of the two push rods 41 are fixedly installed on the upper and lower sides of the pull handle 4, respectively.

[0063] When in use, a mounting groove is opened on the lower forming block 210, and a metal sheet 42 is placed in the mounting groove. When the lower forming block 210 is still in the movable part 102 and has not yet entered the forming groove 104, the metal sheet 42 is pressed against the mounting groove. When the lower forming block 210 enters the forming groove 104, the metal sheet 42 will pop outward under the action of its own elastic force, so that the two ends of the metal sheet 42 are respectively pressed against the inner wall of the forming groove 104 and the outer wall of the lower forming block 210, and then the pull handle 4 is moved, and the pull handle 4 drives the push rod 41 to move, One end of the rod 41 is coated with glue and inserted from the side of the movable part 102, so that the push rod 41 and the metal sheet 42 are adhered together. At this time, the vacuum pump 316 is started and the handle 4 is pulled to move the metal sheet 42 to the right side of the upper molding block 23. Then the upper molding block 23 is inserted into the lower molding block 210. At the same time, the handle 4 is pulled to move the metal sheet 42 to the side where the hydraulic rod 2 is located, so that the metal sheet 42 is sucked tightly on the inner wall of the molding groove 104 away from the side plate 28. At this time, the enclosed space used for molding is between the left side of the metal sheet 42 and the right side of the sealing plate 313.

[0064] In another embodiment different from the aforementioned embodiment, the handle 4 can be replaced with an electric drive element so that the movement of the metal sheet 42 is coordinated with the descent of the upper forming block 23 and the operation of the vacuum pump 316, thereby reducing the operation interval, and a fixing groove is opened at the contact point between the upper forming block 23 and the movable part 102, and a metal plate 314 which is also a memory metal is placed in the fixing groove, so that after the upper forming block 23 and the lower forming block 210 are combined together, under high temperature heating, the metal plate 314 in the fixing groove begins to reset to its initial shape, thereby blocking the gap between the upper forming block 23 and the movable part 102.

[0065] When applied to the field of kitchenware, the oil spout body 1 can be directly cast integrally on the pot to control the oil and water contained in the dishes when they are out of the pot, so as to prevent the soup from flowing along the outer wall of the pot to the bottom of the pot and causing residue on the bottom of the pot. In particular, the cast iron enamel pot is very popular at home and abroad because of its advantages such as being healthy and coating-free, micro-pressure water locking, easy to clean, and having a wide range of applications. However, most of the cast iron enamel pots with oil spouts currently have narrow and steep oil spouts, or no reflux groove is designed under the oil spouts, resulting in that when pouring, the water cannot all pass through the oil spouts, but flows out through the pot body, forming spillage, or continuous dripping, and some drips will flow back to the outer wall of the pot. If the cleaning is not timely and thorough, the ash will accumulate over the years and easily sinter the bottom of the pot, affecting the service life of the pot.

[0066] In another embodiment different from the above-mentioned embodiment:

[0067] The wall thickness of the nozzle body 1 is set to 3.4 mm, the wall thickness of the widest part of the upper wall of the nozzle body 1 is set to 6 mm, the wall thickness of the sharp corner of the lower wall of the nozzle body 1 is set to 2.5 mm, and a waterproof reflux groove is opened on the lower wall of the nozzle body 1. The nozzle body 1 and the pot body are made of one-piece cast iron, and the surface is enamel-treated;

[0068] The angle between the upper wall and the side wall of the nozzle body 1 is 84 degrees, the angle between the upper wall and the lower wall of the nozzle body 1 is 54 degrees, and the angle between the two side walls of the waterproof backflow groove is 81 degrees;

[0069] By increasing the water outlet angle of the nozzle body 1, the centripetal force of the water flow adhering to the wall is increased, so that the water flow falls vertically and flows out cleanly. When the oil, water and soup in the pot body are poured out to the end, the remaining few drops will flow to the outside of the pot body along one side wall of the waterproof reflux groove, and will not flow to the bottom of the pot body along the other side wall of the waterproof reflux groove;

[0070] When die-casting the nozzle body 1 and the pot body in this embodiment, the molding groove 104 opened on the fixed part 103 is designed to fit the shape of the approximately semicircular groove inside the pot body and the nozzle body 1, and the lower molding block 210 is installed on the movable part 102 and designed to fit the bottom of the pot body and the shape of the waterproof backflow groove, and then die-casting can be performed.
