refer to fig. 1, a leak early warning formula cooling system for injection mold, including aqueduct 1, 1 female connection in aqueduct has water injection well choke 2, a plurality of drive grooves 3 have been seted up to the lateral wall of aqueduct 1, 3 interior sealed sliding connection in drive groove have slider 4, a plurality of through-holes 5 have been seted up to 3 inner walls in the drive groove, one-way inlet port 6 has been seted up to the lateral wall of aqueduct 1, one-way inlet port 6 only allows the air to flow out to the aqueduct 1 from aqueduct 1 in, prevent that the coolant liquid in the aqueduct 1 from flowing out, it can specifically be at downthehole installation stop valve. Install the drive arrangement that drive slider 4 removed in the one-way inlet port 6, install piezoceramics piece 9 in the drive groove 3, through-hole 5 sets up the junction at aqueduct 1 and water injection well choke 2, and through-hole 5 is close to piezoceramics piece 9 and sets up, and is specific, on through-hole 5 sets up the interior concave part on aqueduct 1 screw thread section, so can not exert an influence to the sealed effect of aqueduct 1 and water injection well choke 2. The piezoelectric ceramic piece 9 is electrically connected with the warning lamp 10, and the connection mode of the piezoelectric ceramic piece 9 and the warning lamp 10 is a mature technology in the existing electrical field, is irrelevant to the design purpose of the scheme and is not described in detail.
The driving device comprises a reed 7 embedded in the one-way air inlet 6, the side wall of the sliding block 4 is fixedly connected with a vibrating spring 8, and the natural frequencies of the reed 7 and the vibrating spring 8 are the same. By providing reed 7 and vibrating reed 8 having the same natural frequency, vibrating reed 8 vibrates synchronously when reed 7 vibrates.
When the device is used, when cooling liquid flows along the hollow arrow direction in the figure 1, the flow velocity of the cooling liquid in the water guide pipe 1 is high, the flow velocity of air outside the water guide pipe 1 is low, and the flow velocity difference can be generated inside and outside the water guide pipe 1, so that the internal pressure of the water guide pipe 1 is lower than the external pressure, and the air is extruded into the water guide pipe 1 along the one-way air inlet 6 (the air flows to the direction shown by the vertical arrow in the figure 1). When air flows in the one-way air inlet hole 6, the reed 7 is blown, the reed 7 vibrates, the vibrating spring 8 generates resonance, and the vibrating spring 8 can expand and contract after vibration.
If the sealing between the water nozzle 2 and the water guide pipe 1 is good, the through hole 5 is blocked by the side wall of the water nozzle 2, and the driving groove 3 on the right side of the sliding block 4 forms a closed space, so that the vibrating spring 8 cannot stretch and contract to drive the sliding block 4 to move back and forth; when the water nozzle 2 and the water guide pipe 1 are loosened and generate gaps, the through hole 5 between the water nozzle 2 and the water guide pipe 1 is communicated, and the vibrating spring 8 can drive the sliding block 4 to move back and forth when stretching, so that the piezoelectric ceramic piece 9 can be continuously impacted, mechanical energy is converted into electric energy under the piezoelectric effect, and finally the warning lamp 10 can be lightened, and workers can be timely informed that the cooling water channel leaks and stop the machine.
The second embodiment:
referring to fig. 2-3, different from the first embodiment, a water locking ring 11 is sleeved on the water faucet 2, and it should be noted that by providing the water locking ring 11, when leakage occurs, the leaked coolant flows out from a gap between the water locking ring 11 and the water conduit 1, so that the leaked coolant can be conveniently extracted, and the leaked coolant is prevented from overflowing.
The side wall of the water guide pipe 1 is provided with an annular groove 12, a sliding plug 13 is connected in the annular groove 12 in a sealing and sliding manner, a one-way water inlet pipe 15 communicated with the annular groove 12 is installed on the water locking ring 11, a one-way water outlet pipe 16 is arranged at the bottom in the annular groove 12, the one-way water inlet pipe 15 limits the one-way flow of fluid from the one-way water inlet pipe 15 to the annular groove 12, the one-way water outlet pipe 16 limits the one-way flow of fluid from the annular groove 12 to the liquid storage cylinder 17, and particularly, a one-way valve is installed in the water guide pipe. And the water outlet end of the one-way water outlet pipe 16 is communicated with a liquid storage cylinder 17, and a pushing device for pushing the sliding plug 13 to move is arranged in the annular groove 12.
The pushing device comprises a spring 14 fixedly connected to the inner wall of the annular groove 12, one end, far away from the inner wall of the annular groove 12, of the spring 14 is fixedly connected to the side wall of the sliding plug 13, an air hole 18 is formed in the bottom of the annular groove 12, and the air hole 18 is formed in one side, close to the spring 14. It should be noted that the air hole 18 can keep the space on the left side of the sliding plug 13 smooth, so that the sliding plug 13 can move back and forth smoothly. The sliding plug 13 and the sliding block 4 are both made of magnetic materials, and the like magnetic poles of the sliding plug 13 and the sliding block 4 are opposite.
When leakage occurs, the vibrating spring 8 continuously stretches and retracts to drive the magnetic sliding block 4 to reciprocate back and forth, when the sliding block 4 moves rightwards, the sliding block 4 is close to the sliding plug 13, the sliding plug 13 is opposite to the same-name magnetic pole of the sliding block 4, when the sliding block 4 is close to the sliding plug 13, the magnetic repulsion force between the sliding plug 13 and the sliding plug is increased, so that the sliding plug 13 can be pushed to move rightwards, and when the sliding block 4 moves leftwards and resets, the spring 14 pulls the sliding block 4 to move backwards and reset. Therefore, the sliding plug 13 also reciprocates back and forth, and when the sliding plug 13 moves to the right, the space on the right side of the sliding plug 13 can be enlarged, negative pressure is generated, so that leaked cooling liquid is pumped into the annular groove 12 along the one-way water inlet pipe 15, when the sliding plug 13 moves to the left, the pumped cooling liquid is squeezed into the liquid storage barrel 17 along the one-way water outlet pipe 16, and therefore before a worker handles the leaked cooling liquid, the leaked cooling liquid can be continuously and temporarily guided into the liquid storage barrel 17 for storage, and the leaked cooling liquid is prevented from polluting a mold or a product.
