Description

Technical Field

[0002] Plastic bottles are made of materials such as polyethylene or polypropylene, and are commonly used as disposable plastic packaging containers for liquids or solids such as beverages, pickles, honey and cooking oil. In the production process of plastic bottles, an injection molding device is required to inject the raw materials heated at high temperature into a mold.

[0003] In the prior art, a plastic bottle preform injection molding device with patent announcement number CN216443036U is disclosed. The above patent provides a sleeve hole on the inner side of the No. 1 template and the No. 2 template, and provides an active cavity inside the No. 1 template and the No. 2 template, so that the sleeve hole and the active cavity are connected. When the No. 1 template and the No. 2 template are close to each other for sealing, the sleeve rod moves along the sleeve hole and stretches the spring, so that the sleeve rod pushes the sealing plate to achieve the sealing of the water hole, so that the cooling water injected can fully exchange heat inside the No. 1 template and the No. 2 template, thereby improving the heat exchange efficiency of the unit cooling water, avoiding the waste of water resources, and having a good energy-saving effect. However, in actual use, there are still the following deficiencies: most of the existing injection molding devices use a water cooling structure to cool the mold to cool the bottle, but the cooling efficiency is low when only using the water cooling structure, resulting in slow bottle discharge, and the plastic bottles after injection molding need to be manually taken out by the staff, which increases the workload of the staff and greatly reduces the efficiency of taking out the plastic bottles.

[0004] Therefore, an injection molding device with good cooling effect is needed to solve the problems in the prior art that the cooling structure of the injection molding device is relatively simple, resulting in low cooling efficiency and the plastic bottles after injection molding need to be manually removed.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides an injection molding device with good cooling effect, comprising a machine body 1, with cylinders 2 fixedly connected to the outer walls on both sides of the machine body 1, the output ends of the two cylinders 2 respectively slidingly penetrate the inner walls on both sides of the machine body 1 and fixedly connected to mutually matching side molds 3, the centers of the top surfaces of the two side molds 3 are fixedly connected to mutually matching positioning rings 4, the top surfaces of the two side molds 3 are each provided with a groove 5, and the two grooves 5 are each provided with a cooling mechanism 6, and a conveying component 7 is provided inside the machine body 1;

[0023] The cooling mechanism 6 includes a cooling pipe 61 and two mounting grooves 64. The cooling pipe 61 is spiral and is arranged on a side wall inside the groove 5. A water inlet 62 is provided at one end of the cooling pipe 61, and a water outlet 63 is provided at the other end of the cooling pipe 61. The water inlet 62 and the water outlet 63 both extend to the outside of the corresponding side mold 3. The two mounting grooves 64 are both opened through the outer surface of the corresponding side mold 3, and cooling fans 65 are embedded in the two mounting grooves 64.

[0024] Further as Figure 1 and Figure 3 As shown, it is worth mentioning that the conveying assembly 7 includes a support seat 71, two baffles 73 and a fixing frame 74. The bottom surface of the support seat 71 is fixedly connected to the inner wall of the bottom surface of the body 1, and a conveyor belt 72 is installed on the top surface of the support seat 71. The two baffles 73 are respectively located at the two ends of the interior of the body 1 and the outer walls on both sides are respectively fixedly connected to the inner walls on both sides of the body 1. The outer walls on both sides of the fixing frame 74 are respectively fixedly connected to the inner walls on both sides of the body 1. A mounting hole is opened through the center of the top surface of the fixing frame 74 and a buffer bucket 75 is fixedly connected through the mounting hole.

[0025] Further as Figure 1 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the top surface of the machine body 1 is fixedly connected to a material box 8, the bottom surface of the material box 8 is installed with an injection pump 9, the output end of the injection pump 9 passes through the inner wall of the top surface of the machine body 1 and is coaxially fixedly connected to an injection pipe 10.

[0026] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that mounting plates 11 are fixedly connected on both sides of the outer wall at one end of the body 1, the two mounting plates 11 are symmetrically distributed and are fixedly connected to the outer wall at one end away from the body 1, a water tank 12 is installed on the outer wall on one side of the water tank 12, and the output end of the water pump 13 is fixedly connected to a water supply hose 14 which is fixedly connected to the water inlet 62 on the adjacent side mold 3, and a recovery hose 15 is fixedly connected to the bottom of the outer wall on one side of the water tank 12 which is fixedly connected to the water outlet 63 on the adjacent side mold 3.

[0027] Further as Figure 1 and Figure 3 As shown, it is worth mentioning that grooves are formed on both sides of the outer wall of the machine body 1 to facilitate the operation of the conveyor belt 72, so that the conveyor belt 72 can deliver the plastic bottles produced by injection molding from the machine body 1. The buffer bucket 75 is located between the side mold 3 and the conveyor belt 72. The buffer bucket 75 provides a buffering effect for the plastic bottles after injection molding, so that the plastic bottles are buffered when they fall on the surface of the conveyor belt 72, thereby protecting the plastic bottles.

[0028] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the outer diameter of the injection tube 10 is the same as the inner diameter of the two positioning rings 4 after being connected. The bottom end of the injection tube 10 passes through the two positioning rings 4 and is inserted into the inside of the two side molds 3, which greatly improves the sealing during injection molding, makes the injection molding effect better, and effectively improves the yield rate of plastic bottle injection molding production.

[0029] In summary: when the injection molding device is in use, first, the two cylinders 2 are controlled simultaneously to push the two side molds 3 to fit together. At this time, the two positioning rings 4 fit together to form a complete ring body, and the outer surface of the injection tube 10 fits with the inner surface of the two fitting positioning rings 4. Then, the injection pump 9, the cooling fan 65 and the water pump 13 are turned on. The injection pump 9 injects the material into the interior of the two fitting side molds 3. At the same time, the water pump 13 sends the cooling water in the water tank 12 into the interior of the cooling pipe 61 through the water supply hose 14. The spiral cooling pipe 61 effectively takes away the heat on the side mold 3, which is The side mold 3 is cooled. Under the action of the water pump 13, the cooling water flows inside the cooling pipe 61 and then returns to the water tank 12 through the water outlet 63 and the recovery hose 15, thereby realizing the recycling of the cooling water. At the same time, the cooling fan 65 is turned on to accelerate the air flow inside the groove 5 and around the cooling pipe 61, further improving the cooling effect on the side mold 3. After rapid cooling, the material forms a plastic bottle inside the side mold 3, completing the injection molding production of the plastic bottle, effectively avoiding the problem of low cooling efficiency caused by the relatively simple cooling structure of the injection molding device.

[0030] After the injection-molded plastic bottle is cooled and formed, the two cylinders 2 are controlled at the same time to drive the two side molds 3 to separate from each other. At this time, the plastic bottle falls from between the two side molds 3 and falls into the buffer bucket 75. The buffer bucket 75 with an inclined interior provides a buffering effect on the plastic bottle, so that the plastic bottle is better buffered when it falls on the surface of the conveyor belt 72, thereby protecting the plastic bottle. At the same time, the two baffles 73 located at both ends of the conveyor belt 72 effectively protect the plastic bottle from falling from the conveyor belt 72. Finally, the plastic bottle is transported by the rotating conveyor belt 72. The operation is simple, and the problem of manual material removal of the injection-molded plastic bottles is effectively avoided.

[0031] The cooling fan 65, the injection pump 9 and the water pump 13 can be purchased on the market. The cooling fan 65, the injection pump 9 and the water pump 13 are equipped with power supplies. They are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
