Problems solved by technology

[0003] After long-term exposure to high-frequency changes in cold and heat, the components of the cooling system will age and wear, the connection between the water pipe and the faucet will become loose, and the sealing effect will be greatly reduced, so the coolant will leak. The coolant is very easy to contaminate the mold or product. At the same time, the cooling water circuit is set inside the mold. When a leak occurs, it is difficult for the staff to find it at the first time, which will eventually lead to a decline in the qualified rate of large quantities of products.

Embodiment 1

[0024] refer to Figure 1-3 , a leakage self-alarm injection mold cooling system, including a water pipe 1, a water nozzle 2 is connected with a sealing thread in the water pipe 1, and a plurality of strip grooves 4 are opened on the side wall of the water pipe 1. A magnetic block 6 is slidably connected, a helical coil 9 is embedded in the strip groove 4, the helical coil 9 is arranged on the upper half of the strip groove 4, and the water delivery pipe 1 is made of a soft rubber material, and the helical coil 9 is electrically A warning light 13 is connected sexually, and a driving device for driving the magnetic block 6 to move is installed on the magnetic block 6 .

[0025] The driving device includes a telescopic air bag 7 fixedly connected to the lower end of the magnet block 6, and an annular groove 3 is formed on the side wall of the water delivery pipe 1. It should be noted that the telescopic length of the telescopic air bag 7 is greater than the length of the helica...

Embodiment 2

[0030] refer to Figure 4 , Different from the first embodiment, a limit rod 17 is fixedly connected in the water delivery pipe 1, an axial flow impeller 14 is rotatably connected to the limit rod 17, and a first magnetic sheet 15 is fixedly connected to one of the blades of the axial flow impeller 14. , a second magnetic sheet 16 is fixedly connected to the inner wall of the annular groove 3 . It should be noted that when the first magnetic piece 15 and the second magnetic piece 16 are closest to each other, the magnetic poles of the same name between the two are opposite, such as Figure 4 As shown, when the blade provided with the first magnetic piece 15 rotates 180 degrees, it will be the farthest from the second magnetic piece 16, and the opposite magnetic poles of the first magnetic piece 15 and the second magnetic piece 16 are opposite.

[0031] In this embodiment, when the cooling liquid flows through the water delivery pipe 1, it will pass through the blades of the a...

Abstract

The invention discloses a leakage self-alarm type injection mold cooling system, comprising a water delivery pipe, a water nozzle is connected with a sealing thread in the water delivery pipe, and a plurality of strip grooves are opened on the side wall of the water delivery pipe. A magnetic block is slidably connected in the groove, a helical coil is embedded in the strip groove, and a warning light is electrically connected to the helical coil, and a driving device for driving the movement of the magnetic block is installed on the magnetic block. In the present invention, when the sealing effect between the water delivery pipe and the water nozzle decreases and leakage occurs, the cooling liquid enters the strip groove and causes the floating block to float, and at the same time, the driving device makes the magnetic block move up and down continuously, so that the magnetic flux in the helical coil can be made. A change occurs and an induced current is generated, which finally lights up the warning light and informs the staff to deal with the leaking water pipes and faucets.

Description

technical field [0001] The invention relates to the technical field of injection mold related equipment, in particular to a leakage self-alarm type injection mold cooling system. Background technique [0002] The cooling system is one of the eight systems of the injection mold. It is mainly composed of water pipes and nozzles. It is set inside the mold to cool the mold and speed up the condensation molding of the product. [0003] After long-term exposure to high-frequency changes in cold and heat, various components of the cooling system will experience aging, wear, etc., the connection between the water pipe and the faucet will become loose, and the sealing effect will be greatly reduced, so there will be coolant leakage. The cooling liquid is very easy to contaminate the mold or the product, and the cooling water circuit is set inside the mold. When a leak occurs, it is difficult for the staff to find it at the first time, which eventually leads to a decrease in the quali...
