Description

Technical Field

[0001] This utility model relates to the field of cooling water system technology, and in particular to a cooling water system for injection molds. Background Technology

[0002] Injection molds are precision tools that inject molten plastic into a cavity under high pressure to form molded products. Their built-in cooling water circuit uses copper alloy pipes linked with an intelligent temperature control module to circulate and regulate the water temperature, which greatly shortens the injection cycle and reduces energy consumption. They are widely used in the production of high-gloss parts such as automotive lamp covers and electronic connectors.

[0003] The cooling water circulation speed of existing injection mold cooling water circuit machines is relatively slow, which is not conducive to the cooling of injection molds. During the cooling water circulation process, the cooling water evaporates when heated and is difficult to liquefy into water quickly. In the process of liquefaction into water, it is also easy to lose into the external air, which leads to the need to repeatedly add cooling water to replenish it. In addition, the cooling water flows slowly in the cooling tank in traditional water circuit machines, which is not conducive to the rapid cooling of injection molds. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cooling water system for injection molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling water system for an injection mold includes a base, a motor fixedly connected to the base, a cooling box, and a cooling tower.

[0007] Preferably, a connecting ring is fixedly connected to the third rotating shaft, a long rod is fixedly connected to the lower side of the connecting ring, a chiller is fixedly connected to one side of the cooling tower, and a conduit is fixedly connected to one side of the chiller.

[0008] Preferably, a fourth shaft, a second gear, and a fifth shaft are rotatably connected to the base. The motor output end and the fourth shaft are connected by a third pulley assembly. A first gear is fixedly connected to the fourth shaft, and the first gear and the second gear mesh with each other. A third gear is fixedly connected to the fifth shaft, and the third gear and the second gear mesh with each other. Multiple third bevel gears are fixedly connected to the fifth shaft.

[0009] Preferably, a plurality of connecting pipes are fixedly connected to one side of the cooling box, and a sixth rotating shaft is rotatably connected inside each connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a refrigeration unit and a conduit to assist in the liquefaction of cooling water after it is converted into water vapor inside the cooling tower. A connecting ring and a long rod are installed in the cooling tower to quickly guide the water liquefied on the inner wall of the cooling tower to the bottom of the cooling tower, which facilitates the subsequent generation of liquefied water. Through the setting of a third rotating shaft and fan blades, the fan blades accelerate the contact between the water vapor and the conduit on the inner wall of the liquefaction tower, promote the generation of liquefied water, accelerate the circulation of cooling water, and promote the cooling of the injection mold.

Through the cooperation of the fifth rotating shaft, the third bevel gear and the fourth bevel gear, the power is transmitted to the sixth rotating shaft, thereby driving the spiral blade to rotate. This causes the liquefied water to flow from the direction of the water inlet pipe in the cooling box to the direction of the outlet pipe, accelerating the flow of cooling water in the cooling box, thereby accelerating the circulation of cooling water and promoting the cooling of the injection mold.

The fan blades 15 can accelerate the movement of water vapor and promote the liquefaction of water vapor. A water inlet pipe 4 is fixedly connected to one side of the cooling box 3. A water pump 5 is installed on the water inlet pipe 4. The water pump 5 and the cooling tower 7 are connected to the cooling tower 7 through a water supply pipe 6. A water delivery pipe 36 is fixedly connected to one side of the water pump 5. A valve 37 is installed on the water delivery pipe 36. The valve 37 can control the supply of cooling water to the cooling box 3 by the water delivery pipe 36. A placement hole 38 is fixedly connected to the cooling box 3. The injection mold performs injection molding on the placement hole 38. A return port 22 is fixedly connected to the cooling tower 7. The return port 22 is used to liquefy a small amount of water vapor that enters the cooling tower 7 again and turn it into cooling water for return. A top bracket 23 is fixedly connected to the return port 22 to facilitate the liquefaction of water vapor. A guide hole 21 is opened in the third shaft 14 to facilitate the return of liquefied cooling water.

[0021] A connecting ring 16 is fixedly connected to the third rotating shaft 14, and a long rod 17 is fixedly connected to the lower side of the connecting ring 16. A chiller 19 is fixedly connected to one side of the cooling tower 7. The chiller 19 drives the compressor by consuming electrical energy, causing the refrigerant to circulate in the system, undergoing four processes: compression, liquefaction, throttling, and evaporation. This continuously absorbs heat from the low-temperature environment inside the cooling tower 7 and releases heat to the high-temperature environment outside the cooling tower 7, achieving the purpose of forced cooling. This is existing technology and will not be elaborated further. A conduit 20 is fixedly connected to one side of the chiller 19. The conduit 20 is used to conduct the cooling effect generated by the chiller 19. A fourth rotating shaft 26, a second gear 28, and a fifth rotating shaft 30 are rotatably connected to the base 1.

The whole assembly is used to transmit the movement between the shafts. This is existing technology and will not be described in detail.

[0022] In this invention, when cooling water circulation is required, the motor 2 and the chiller 19 are first started. The output of the motor 2 drives the first shaft 9 to rotate via the first pulley assembly 8. The first shaft 9 drives the first bevel gear 10 to rotate, which in turn drives the second bevel gear 11 to rotate. The second bevel gear 11 drives the second shaft 12 to rotate, which in turn drives the third shaft 14 to rotate via the second pulley assembly 13. The third shaft 14 drives the fan blades 15 to rotate, and simultaneously drives the connecting ring 16 to rotate. The connecting ring 16 drives the long rod 17 to rotate along the inner wall of the cooling tower 7, drawing liquefied water from the inner wall of the cooling tower 7 into the bottom of the cooling tower 7. The rotation of the fan blades 15 promotes cooling. The rising of water vapor after heating accelerates the contact between the water vapor and the conduit 20, causing it to liquefy back into water. Simultaneously, the output of motor 2 drives the fourth shaft 26 to rotate via the third pulley assembly 25. The fourth shaft 26 drives the first gear 27 to rotate, which in turn drives the second gear 28 to rotate. The second gear 28 drives the third gear 29 to rotate, which in turn drives the fifth shaft 30 to rotate. The fifth shaft 30 drives the third bevel gear 32 to rotate, which in turn drives the fourth bevel gear 33 to rotate. The fourth bevel gear 33 drives the sixth shaft 34 to rotate, which in turn drives the spiral blades 35 to rotate. This accelerates the flow of cooling water in the cooling tank 3 and promotes the cooling of the injection mold.
