In the injection molding process, the cooling link of the mold is crucial, and reasonable and efficient cooling can effectively shorten the molding cycle, improve production efficiency, and at the same time ensure the dimensional accuracy and physical properties of the injection molded part

[0003] The traditional cooling system of injection molding machine mostly uses natural cooling or simple water cooling method. Natural cooling is slow, which seriously restricts production efficiency. And the water temperature will gradually rise after long-time use of ordinary water cooling method, which will cause a significant decline in cooling effect. Therefore, it is necessary to frequently replace the cooling water, which not only causes waste of water resources, but also increases production cost. Therefore, an injection molding machine for high-strength wear-resistant injection molded part is proposed to solve the above problems. SUMMARY

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4An injection molding machine for high-strength wear-resistant injection molded parts includes a base plate 1, a lower mold 2 fixedly mounted on the top side of the base plate 1, an upper mold 5 disposed above the lower mold 2, a water tank 6 fixedly mounted on the bottom side of the base plate 1, a partition 7 fixedly mounted inside the water tank 6, the water tank 6 being divided into two areas by the partition 7, multiple heat dissipation holes being provided in the left side area of ​​the water tank 6, a fixing column 20 fixedly mounted on the inner wall of one side of the water tank 6, a second pulley 21 movably sleeved on the outer side of the fixing column 20, and multiple fan blades fixedly mounted on one side of the second pulley 21. 23. Multiple fan blades 23 all face the heat dissipation holes. An agitation assembly is provided in the left area of ​​the water tank 6. A water cooling assembly is provided above the base plate 1. The agitation assembly includes a motor 16 fixedly installed on one side of the water tank 6. The output end of the motor 16 rotates through the water tank 6 and is fixedly installed with a rotating rod 17. The other end of the rotating rod 17 is rotatably connected to the inner wall of one side of the water tank 6. Multiple agitation plates 18 are fixedly installed on the outer side of the rotating rod 17. A first pulley 19 is fixedly sleeved on the outer side of the rotating rod 17. The first pulley 19 and the second pulley 18 are connected to the second pulley 19. The pulleys 21 share the same belt 22. When warm water enters the left side of the water tank 6, the motor 16 is started. The motor 16 drives the rotating rod 17 to rotate. Since multiple agitator plates 18 are fixedly installed on the outside of the rotating rod 17, these agitator plates 18 will stir the warm water in the left side of the water tank 6 when the rotating rod 17 rotates. Through stirring, the contact area between the warm water and the air increases, and the heat dissipation is accelerated, thereby achieving rapid cooling. In addition, the first pulley is fixedly sleeved on the outside of the rotating rod 17. 19. The first pulley 19 and the second pulley 21 share the same belt 22. Under the transmission action of the belt 22, the second pulley 21 starts to rotate. Multiple fan blades 23 are fixedly installed on one side of the second pulley 21. The fan blades 23 rotate with the rotation of the second pulley 21. The generated wind will exhaust the hot air in the water tank 6 from the heat dissipation holes. The wind accelerates the exchange between the hot air and the outside air, further removing the heat in the left area. Under the dual action of stirring and air cooling, the cooling speed of the water source on the left side of the water tank 6 is significantly accelerated.

[0023] Specifically, the water-cooling assembly includes a frame-shaped water pipe 8 fixedly sleeved on the outer side of the lower mold 2. One end of the frame-shaped water pipe 8 is fixedly connected to a water outlet pipe 9, and the other end of the water outlet pipe 9 passes through the base plate 1 and faces the left side of the water tank 6. A water pump 10 is fixedly installed on the top side of the base plate 1. A delivery pipe 11 is fixedly installed on one side of the water pump 10. The other end of the delivery pipe 11 is fixedly connected to the other end of the frame-shaped water pipe 8 and communicates with the frame-shaped water pipe 8. An extraction pipe 12 is fixedly connected to the other side of the water pump 10, and the other end of the extraction pipe 12... Extending to the right side of the water tank 6, a frame-shaped water pipe 8 is installed. When cooling of the lower mold 2 is required, the water pump 10 drives the extraction pipe 12 to extract water from the right side of the water tank 6. The extracted water is then transported to the frame-shaped water pipe 8 through the delivery pipe 11. When the water flows in the frame-shaped water pipe 8, it can carry away the heat of the lower mold 2, which can further accelerate the cooling and forming. The water that carries away the heat of the lower mold 2 will enter the left side of the water tank 6 through the water outlet pipe 9.

[0024] Specifically, a circulation pump 13 is fixedly installed on one side of the water tank 6, and a water pumping pipe 14 and a water delivery pipe 15 are fixedly installed on both sides of the circulation pump 13. The other ends of the water pumping pipe 14 and the water delivery pipe 15 extend to the left and right sides of the water tank 6, respectively. By setting up the circulation pump 13, when the warm water in the left side area cools down, starting the circulation pump 13 will allow the water pumping pipe 14 to draw the cooled water, and then the cooled water will be transported to the right side area through the water delivery pipe 15, thus realizing the recycling of water resources.

[0025] Specifically, a bracket 3 is fixedly installed on the top side of the base plate 1. The bracket 3 is L-shaped, and a cylinder 4 is fixedly installed on the top side of the bracket 3. The output end of the cylinder 4 passes through the bracket 3 and is fixedly connected to the top side of the upper mold 5. By setting the cylinder 4, when injection molding is required, the cylinder 4 is started to drive the upper mold 5 to move down. When the upper mold 5 comes into contact with the lower mold 2, a mold cavity is formed, and then the injection molding process can be carried out.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: During mold injection, first, cylinder 4 is activated. Cylinder 4 moves the upper mold 5 downwards. When the upper mold 5 and lower mold 2 are tightly fitted together, a closed mold cavity is formed. At this point, plastic is injected into the mold cavity through the upper mold 5, completing the initial stage of the injection molding operation. Next, water pump 10 is activated. After water pump 10 starts running, water is drawn from water tank 6 through extraction pipe 12. The drawn water is then transported to frame-shaped water pipe 8 through delivery pipe 11. When the water flows in frame-shaped water pipe 8, it effectively irrigates the lower mold 2. Cooling is performed, and under the influence of the low-temperature environment, the plastic in the lower mold 2 can be molded more quickly. The water that carries away the heat from the lower mold 2 will flow along the outlet pipe 9 to the left side of the water tank 6. At the same time, the motor 16 is started synchronously, and the motor 16 drives the rotating rod 17 to rotate. Since multiple stirring plates 18 are fixedly installed on the outside of the rotating rod 17, these stirring plates 18 will stir the warm water in the left side of the water tank 6 when the rotating rod 17 rotates. Through stirring, the contact area between the warm water and the air increases, and the heat dissipation is accelerated. To achieve rapid cooling, a first pulley 19 is fixedly sleeved on the outer side of the rotating rod 17. The first pulley 19 and the second pulley 21 share the same belt 22. Under the transmission action of the belt 22, the second pulley 21 begins to rotate. Multiple fan blades 23 are fixedly installed on one side of the second pulley 21. The fan blades 23 rotate with the rotation of the second pulley 21, and the generated wind force will exhaust the hot air in the water tank 6 through the heat dissipation holes. Under the dual action of stirring and air cooling, the cooling speed of the water source on the left side of the water tank 6 is significantly accelerated, and the water in the lower mold 2 cools down rapidly. After the plastic cools and solidifies, cylinder 4 is restarted to move the upper mold 5 upward. At this time, the operator can remove the cooled mold from the lower mold 2. In order to realize the recycling of water resources, a circulation pump 13 is set up. When the water source in the left area of ​​water tank 6 has cooled down, the circulation pump 13 is started. When the circulation pump 13 is running, the cooled water source is drawn through the water pumping pipe 14 and then transported back to the right area of ​​water tank 6 through the water delivery pipe 15 to prepare for the next injection molding cooling operation.
