Description

Technical Field

[0001] The invention relates to the technical field of removing accumulated water from a cooling pipeline, and in particular to a method and a device for removing accumulated water from a mold water channel. Background Art

[0002] At present, in the production process of plastic injection molding or hardware die-casting industry, the molds needed for production are often equipped with cooling water circuits to reduce the temperature of the mold during production and improve production efficiency. However, cooling water has a certain corrosive effect on mold steel. Therefore, when the mold is not in use, the accumulated water inside the mold water circuit must be cleaned up. Otherwise, the water staying in the mold water circuit will easily produce rust inside the mold. Over time, the rust will narrow the mold water circuit, and seriously block the mold water circuit, thereby affecting the cooling of the mold and reducing production efficiency. The current method of clearing the accumulated water inside the mold water circuit is to rely on technicians to close the water inlet of the mold and unplug the water pipe and then use an air gun to blow out the water circuit one by one.

[0003] The above traditional operation has the following disadvantages:

[0004] 1. It needs to be operated manually by technicians, and the mold water channels need to be blown off one by one;

[0005] 2. In actual work, technicians often shut off the water supply to the mold and pull out the water inlet and return pipes of the mold when the machine stops working, but they often forget or, due to limited on-site conditions, omit the action of blowing away the accumulated water in the mold water channel.

[0006] 3. Because the accumulated water in the mold waterway cannot be removed in time and effectively, the mold waterway is prone to rust and scale, which eventually leads to mold waterway blockage, affecting mold cooling and reducing production efficiency. To this end, we have introduced a method and device for removing accumulated water in the mold waterway. Summary of the invention

[0023] Preferably, a sealing ring is sleeved on the outer side of the rotating rod, and the sealing ring is embedded in the valve body;

[0024] The spherical valve core is arranged in the valve core channel inside the valve body, and a tapered pipe and a fixing frame are respectively fixed at both ends of the valve body, the three-way pipe and the valve core channel are connected through the tapered pipe, a check rubber ring is arranged at the other end of the valve core channel, and a valve core through hole is arranged in the middle of the spherical valve core;

At the same time, the buckle assembly drives the spherical valve core to open through the transmission assembly, so that the air pump blows air into the water pipe through the valve body and the three-way pipe in turn, which is used to blow away the accumulated water in the water pipe, thereby solving the trouble of manual operation by technicians. While closing the coolant from entering the water pipe, the accumulated water in the water pipe is automatically blown away, thereby preventing the hidden danger of technicians forgetting or being negligent and failing to clear the accumulated water in the water pipe of the mold, thereby solving the inconvenience of manually blowing away the accumulated water in the water pipe, and ensuring that the water pipe of the mold is not rusted or blocked.

[0052] A device for clearing water from a mold water channel comprises an air pump 6, a water inlet pipe 5 and a water channel pipe 1 embedded in the mold, wherein the water inlet of the water channel pipe 1 is connected to a docking joint 3 and a valve body 24 via a tee pipe 2, the end of the water inlet pipe 5 is connected to a socket 4, and the water inlet pipe 5 is connected to a tapered pipe 401 via a connecting hole 406 inside the socket 4.

[0053] A check assembly is provided inside the water inlet channel 27;

[0054] The check assembly includes a check plate 303 movably connected to a slot 304 on the side of the water inlet channel 27 through a pin 302 and a second spring 301 fixed inside the slot 304, the other end of the second spring 301 is fixed to the middle of the check plate 303, and the other end of the check plate 303 extends out of the slot 304;

[0055] After the conical tube 401 is inserted into the water inlet channel 27, the conical tube 401 passes between the two sets of check plates 303, so that the two sets of check plates 303 rotate and open (such as Fig. 9 and 10 shown);

[0056] After the conical tube 401 is separated from the water inlet channel 27, the second spring 301 pulls the check plate 303 to rotate around the pin shaft 302, so that the two sets of check plates 303 rotate and close. In this way, when the air pump 6 is working, air is blown into the water pipe 1 through the hose 26, the valve body 24, the conical pipe 23 and the three-way pipe 2 in sequence, and the two sets of check plates 303 are closed to prevent the air flowing through the three-way pipe 2 from flowing out from the other end of the water inlet channel 27.

[0057] The side of the butt joint 3 is connected with a snap assembly through a bracket;

[0058] The bracket includes a horizontal plate 21 integrally formed and arranged on the side of the butt joint 3 and a vertical plate 11 connected to the side of the horizontal plate 21;

[0059] The buckle assembly includes a push rod 12 penetrating the longitudinal plate 11, a U-shaped seat 33 connected to the inner end of the push rod 12, a roller 34 movably connected inside the U-shaped seat 33, and a clamping block 35 connected to the bottom of the side of the U-shaped seat 33;

[0060] The push rod 12 is sleeved with a first spring 32, and both ends of the first spring 32 are located between the U-shaped seat 33 and the longitudinal plate 11 (such as Figure 1 , 5 , 6, 9 and 11).

[0061] The side of the socket 4 is provided with a front plane 402, an inclined plane 403 and a rear plane 404 in sequence. Figure 4 shown);

[0062] The roller 34 rolls on the front plane 402, the inclined plane 403 and the rear plane 404;

[0063] The end of the socket 4 is also provided with a slot 405 for inserting the card block 35, and a rectangular frame 38 is sleeved after the card block 35 extends out of the slot 405. The upper and lower ends of the rectangular frame 38 are provided with buckle convex plates 37. The middle of the card block 35 is provided with a V-shaped groove 36, and a locking bolt 9 (such as Figure 6 and 7 shown).

[0064] After the tapered tube 401 at the end of the socket 4 is inserted into the water inlet channel 27 inside the docking head 3, the buckle assembly is used to clamp and fix the socket 4. At the same time, the buckle assembly drives the spherical valve core 30 in the valve body 24 to close through the transmission assembly on the bracket;

[0065] After the socket 4 is pulled out, the socket 4 pushes the buckle assembly to connect the power-on assembly on the bracket, which is used to energize the motor 7 on the air pump 6. At the same time, the buckle assembly drives the spherical valve core 30 to open through the transmission assembly, so that the air pump 6 blows air into the water pipe 1 through the valve body 24 and the three-way pipe 2 in turn.

[0066] The outer end of the push rod 12 extends through the longitudinal plate 11 and is connected to a conductive metal plate 14;

[0067] The power supply assembly includes two sets of limit plates 13 fixed to the sides of the longitudinal plate 11, a terminal 19 fixed to the end of the limit plate 13, and a contact conductive column 20 fixed to the inner end of the terminal 19, and the contact conductive column 20 extends through the rectangular groove 15 on the limit plate 13;

[0068] The two ends of the conductive metal plate 14 are slidably connected to the corresponding rectangular grooves 15, so that when the push rod 12 moves along the through hole on the longitudinal plate 11, it can ensure that the push rod 12 keeps moving in the horizontal straight line direction;

[0069] The two ends of the conductive metal plate 14 are connected to the positive and negative electrodes of the power supply through wires, and the positive and negative terminals on the motor 7 are connected to the corresponding terminals 19 through wires. After the motor 7 is powered on, it is used to drive the impeller inside the air pump 6 to rotate, and discharge the outside air into the valve body 24 through the hose 26. The motor 7 is fixed on the top of the mounting frame 8.

[0070] The transmission assembly includes a rack 17 connected through a vertical plate 16 in the middle of the lower end of the conductive metal plate 14, a rotating rod 10 fixed to the side of the spherical valve core 30, and a gear 18 connected after the rotating rod 10 extends out of the valve body 24 and passes through the horizontal plate 21, and the gear 18 is meshed with the upper end of the rack 17.

[0071] A sealing ring 22 is sleeved on the outer side of the rotating rod 10 , and the sealing ring 22 is embedded in the valve body 24 . The sealing ring 22 seals the connection between the rotating rod 10 and the valve core channel 28 .

[0072] The spherical valve core 30 is arranged in the valve core channel 28 inside the valve body 24, and the two ends of the valve body 24 are respectively fixed with a tapered pipe 23 and a fixing frame 25, so that the three-way pipe 2 and the valve core channel 28 are connected through the tapered pipe 23, and the other end of the valve core channel 28 is provided with a check rubber ring 31, and a valve core through hole 29 is provided in the middle of the spherical valve core 30;

[0073] The check rubber ring 31 is in close contact with the spherical valve core 30. Figure 8 In the state shown, it is used to prevent the cooling water flowing through the three-way pipe 2 from entering the hose 26 via the tapered pipe 23 and the valve core channel 28.

[0074] The air outlet of the air pump 6 is connected to a hose 26 , and the end of the hose 26 is connected to the fixing frame 25 .

[0075] The present invention also provides a method for removing water from a mold water channel, which specifically comprises the following steps:

[0076] S1, after the tapered tube 401 at the end of the socket 4 is inserted into the water inlet channel 27 inside the docking head 3, the buckle assembly is used to clamp the socket 4, so that the socket 4 is fixed to the docking head 3;

[0077] S2. At the same time, the buckle assembly drives the spherical valve core 30 in the valve body 24 to rotate through the transmission assembly on the bracket, so that the spherical valve core 30 closes the water inlet channel 27 (such as Figure 8 shown);

[0078] S3. After the socket 4 is pulled out, the socket 4 pushes the buckle assembly so that the power-on assembly powers the motor 7. At the same time, the buckle assembly drives the spherical valve core 30 to rotate through the transmission assembly, so that the spherical valve core 30 opens the water inlet channel 27 (such as Fig.12 As shown), the air pump 6 blows air into the water pipe 1 through the valve body 24 and the three-way pipe 2 in sequence, so as to blow away the accumulated water in the water pipe 1.

[0079] Specifically, when in use, after the conical tube 401 at the end of the socket 4 is inserted into the water inlet channel 27 inside the butt joint 3, the conical tube 401 passes between the two sets of check plates 303, so that the two sets of check plates 303 rotate and open (such as Fig. 9 and 10 shown);

[0080] At the same time, the roller 34 rolls to the surface of the rear plane 404 via the front plane 402 and the inclined plane 403 in sequence, so that under the elastic force of the first spring 32 on the U-shaped seat 33, the roller 34 is tightly pressed against the surface of the rear plane 404, thereby achieving the clamping and fixing of the socket 4;

[0081] At this time, the block 35 on the U-shaped seat 33 extends out through the slot 405, and then the rectangular frame 38 can be manually put on the block 35, and the buckle convex plate 37 is closely attached to the surface of the socket 4, and finally the locking bolt 9 is screwed into the V-shaped groove 36, so that the V-shaped groove 36 is opened, so as to realize the fixation of the rectangular frame 38 and the block 35 (such as Figure 7 shown);

[0082] At the same time, the U-shaped seat 33 moves away from the longitudinal plate 11, and the U-shaped seat 33 drives the rack 17 to move toward the longitudinal plate 11 through the push rod 12, the conductive metal plate 14 and the vertical plate 16;

[0083] At this time, the rack 17 drives the rotating rod 10 to rotate through the gear 18, and the rotating rod 10 drives the spherical valve core 30 to rotate until the valve core through hole 29 is in a vertical state (such as Figure 8 As shown), to close the valve core channel 28 through the spherical valve core 30;

[0084] Then the PLC controls the water pump to work, and the water pump draws the cooling water in the water tank into the water pipe 1 through the water inlet pipe 5, the connecting hole 406, the tapered pipe 401, the water inlet channel 27 and the three-way pipe 2, and the cooling water enters the water tank through the return pipe at the other end of the water pipe 1, thereby realizing the circulation of cooling water in the water pipe 1, which is used to reduce the temperature of the mold during injection molding production and improve production efficiency.

[0085] After the injection molding production is completed, the PLC stops the water pump, removes the locking bolt 9 and the rectangular frame 38, and then pulls the socket 4 outward. After the conical tube 401 is separated from the water inlet channel 27, the second spring 301 pulls the check plate 303 to rotate with the pin shaft 302 as the center, so that the two sets of check plates 303 rotate and close;

[0086] At the same time, the roller 34 rolls to the surface of the front plane 402 via the rear plane 404 and the inclined plane 403 in sequence, so that the U-shaped seat 33 is close to the longitudinal plate 11, the U-shaped seat 33 makes the first spring 32 in a compressed state, and the conductive metal plate 14 moves along the rectangular groove 15 until the conductive metal plate 14 contacts the contact conductive column 20 (such as Fig.11 As shown), the power supply is used to supply power to the motor 7;

[0087] At the same time, the U-shaped seat 33 drives the rack 17 to move away from the longitudinal plate 11 through the push rod 12, the conductive metal plate 14 and the vertical plate 16. At this time, the rack 17 drives the rotating rod 10 to rotate through the gear 18, and the rotating rod 10 drives the spherical valve core 30 to rotate until the valve core through hole 29 is in a horizontal state (such as Fig.12 As shown), to open the valve core channel 28 through the spherical valve core 30;

[0088] The air pump 6 works to blow air into the water pipe 1 through the hose 26 , the valve body 24 , the tapered pipe 23 and the tee pipe 2 in sequence, so as to blow away the accumulated water in the water pipe 1 .

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
