DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: a cooling component of a vertical turntable injection molding machine, including a support column 1. An injection mold is arranged on one side of the support column 1, and the injection mold includes an upper mold 8 and a lower mold 9, and the upper mold 8 is slidably arranged above the lower mold 9. The upper mold 8 and the lower mold 9 cooperate to inject the material. An air cavity 10 is rotatably arranged between the upper mold 8 and the lower mold 9. An air pipe 12 is fixedly arranged on the support column 1, and the air cavity 10 is connected to the external high-pressure cooling gas through the air pipe 12. A plurality of air holes 13 are evenly opened on the air cavity 10. The air cavity 10 cools the upper mold 8 and the lower mold 9 by the high-pressure cooling gas.

[0021] The upper and lower ends of the air cavity 10 are fixedly provided with rubber rings 14. The rubber rings 14 protect the upper mold 8 and the lower mold 9 to prevent the air cavity 10 from colliding with the upper mold 8 or the lower mold 9. At the same time, the rubber rings 14 are deformed to fit closely with the bottom end of the upper mold 8 and the upper end of the lower mold 9, respectively. When the air cavity 10 sprays air, it has sufficient pressure to penetrate through the gap or hole between the upper mold 8 and the lower mold 9, and quickly and efficiently remove the accumulated heat.

[0022] A primary arm 2 is fixedly welded to one side of the support column 1. A secondary arm 7 is fixedly arranged on the upper end of the support column 1 on the same side as the primary arm 2. A driving member is arranged on the primary arm 2, and the driving member cooperates with the upper mold 8 to move the upper mold 8 up and down. The driving member is connected to the air cavity 10 through a linkage. The upper mold 8 rotates the air cavity 10 through the linkage during the movement.

[0023] The driving member includes a push rod 3. The push rod 3 is an electric push rod. The push rod 3 is fixedly mounted on the upper end of the primary support arm 2. The push rod 3 is vertically arranged. The telescopic end of the push rod 3 is fixedly connected to a power arm 4, and the power arm 4 is arranged horizontally on the left and right. One end of the power arm 4 away from the push rod 3 is fixedly connected to the upper mold 8.

[0024] The linkage part is a rotating shaft 5. A through hole is provided on both the primary support arm 2 and the secondary support arm 7, and the through hole on the primary support arm 2 corresponds to the through hole on the secondary support arm 7. The rotating shaft 5 is rotatably installed in the through holes of the primary support arm 2 and the secondary support arm 7 through a bearing 6. The axis of the rotating shaft 5 is vertically arranged up and down. A through hole is provided on the power arm 4, and the through hole and the rotating shaft 5 are both slidably matched and rotatably matched.

[0025] Two guide posts 15 are symmetrically fixedly arranged on the inner wall of the through hole. The guide posts 15 are arranged horizontally. Two grooves are symmetrically provided on the outer circumferential surface of the rotating shaft 5. The grooves include a straight groove 17 and an arc groove 16. The straight groove 17 is located at the lower part of the rotating shaft 5, and the arc groove 16 is located at the upper part of the rotating shaft 5, and the arc groove 16 is connected to the straight groove 17. The guide posts 15 and the arc groove 16 are slidably matched to rotate the rotating shaft 5. An air cavity support arm 11 is fixedly arranged on the rotating shaft 5, and one end of the air cavity support arm 11 away from the rotating shaft 5 is fixedly connected to the air cavity 10.

[0026] In summary, after the raw material is injection molded in the upper mold 8 and the lower mold 9, the upper mold 8 and the lower mold 9 need to be cooled. The push rod 3 is started, and the telescopic end of the push rod 3 extends to drive the power arm 4 to move upward, and the power arm 4 moves the upper mold 8 upward. The upper mold 8 moves upward until the distance from the lower mold 9 is greater than the height of the air cavity 10, and the push rod 3 stops. The finished product can be taken out.

[0027] During this process, the power arm 4 moves upward with the guide column 15, and the guide column 15 slides in the straight groove 17. When the distance between the upper die 8 and the lower die 9 is greater than the height of the air cavity 10, the guide column 15 enters the arc groove 16, and the guide column 15 continues to move upward with the power arm 4. The guide column 15 cooperates with the arc groove 16 to rotate the rotating shaft 5, and the rotating shaft 5 rotates with the air cavity support arm 11, and the air cavity support arm 11 rotates with the air cavity 10 so that the air cavity 10 rotates to between the upper die 8 and the lower die 9, and the push rod 3 stops. Since the distance between the upper die 8 and the lower die 9 is greater than the height of the air cavity 10, the air cavity 10 does not collide with the upper die 8 and the lower die 9 during the rotation process.

[0028] The high-pressure cooling gas enters the air cavity 10 through the air pipe 12, and the high-pressure cooling gas in the air cavity 10 is ejected through the air hole 13 to cool the upper mold 8 and the lower mold 9. The setting of the rubber ring 14 enables the upper mold 8 and the lower mold 9 to quickly and efficiently take away the accumulated heat.

[0029] During the separation process of the upper mold 8 and the lower mold 9, the air cavity 10 is transferred between the upper mold 8 and the lower mold 9, and the upper mold 8 and the lower mold 9 are cooled by high-pressure cooling gas, which saves time cost and improves work efficiency.

[0030] After the cooling is completed, the high-pressure cooling gas stops being delivered. The push rod 3 causes the power arm 4 to move downward with the upper mold 8 and the guide column 15. The guide column 15 cooperates with the arc groove 16 to make the rotating shaft 5 rotate in the opposite direction. The rotating shaft 5 supports the air cavity 10 through the air cavity 10 arm to make the air cavity 10 rotate out from between the upper mold 8 and the lower mold 9. After the air cavity 10 rotates out, the guide column 15 enters the straight groove 17 and slides in the straight groove 17. The upper mold 8 continues to move downward and engages with the lower mold 9 to inject the raw material.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
