Description

Technical Field

[0001] The utility model belongs to the technical field of plastic injection molding, and particularly relates to an air-cooling structure for plastic processing injection molding. Background Technique

[0002] Plastic processing, also known as plastic shaping processing, is the general term for various processes that convert synthetic resins or plastics into plastic products, and it is a relatively large production department in the plastic industry. Plastic processing generally includes plastic batching, molding, machining, joining, finishing, and assembly, etc. The latter four processes are carried out after the plastic has been formed into products or semi-products, and are also known as plastic secondary processing.

[0003] In order to cool the plastic after injection molding, it is necessary to use a fan for heat dissipation. However, the existing air-cooling structure can only cool the outer shell of the injection molding machine during use and cannot cool the inside of the injection molding machine, resulting in a low cooling efficiency, thereby increasing the plastic processing time and leading to a low plastic processing efficiency. For this reason, we have proposed an air-cooling structure for plastic processing injection molding. Content of the Utility Model

[0004] In order to solve the problem that the existing air-cooling structure can only cool the outer shell of the injection molding machine during use and cannot cool the inside of the injection molding machine, resulting in a low cooling efficiency, thereby increasing the plastic processing time and leading to a low plastic processing efficiency, the utility model provides the following technical solution: An air-cooling structure for plastic processing injection molding, including a bottom plate, a lower mold is fixedly connected to the center of the top of the bottom plate, four hydraulic cylinders are fixedly connected to the top of the bottom plate, an upper mold is fixedly connected to the top of the four hydraulic cylinders, the upper mold is used in cooperation with the lower mold, a cross bar is fixedly connected to the side of the upper mold, a first fixing rod is fixedly connected to the bottom of the cross bar, a concave hole is provided on the side of the first fixing rod, a support rod is slidably inserted into the concave hole, a fan is fixedly connected to the inner side of the support rod, limiting rods are fixedly connected to both sides of the top of the bottom plate, a limiting plate is fixedly connected to the top of the limiting rod, the inner side of the limiting plate is inclined, the other end of the support rod is inclined, and the inclined angle of the support rod is the same as the inclined angle of the limiting plate.

[0005] Preferably, sliding rods are fixedly connected to the top and bottom of the inner cavity of the concave hole of the first fixing rod, sliders are fixedly connected to the other ends of the two sliding rods, a sliding groove is provided in the inner cavity of the support rod, and the sliders are slidably inserted into the sliding groove.

[0006] Preferably, a second fixing rod is fixedly inserted into the inner cavity of the sliding groove, a through hole is provided on the side of the slider, and the slider is slidably sleeved on the second fixing rod through the through hole.

[0007] Preferably, a spring is sleeved on the circumferential surface of the second fixing rod. One end of the spring is fixedly connected to the inner wall of the chute, and the other end of the spring is fixedly connected to the side surface of the slider.

[0008] Preferably, the number of the air blowers is two. The two air blowers are respectively located on both sides above the bottom plate, and both the two air blowers are arranged obliquely downward.

[0009] Preferably, the number of the limiting plates is two. The two limiting plates are respectively located on both sides of the top of the bottom plate, and the two limiting plates are correspondingly arranged with the two support rods.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The hydraulic cylinder drives the upper die to slide downward. The upper die will slide downward until it fits with the lower die, so as to cooperate with the upper die and the lower die. Then, injection molding is carried out through the injection port at the top of the upper die. The air blowers are electrically connected and can blow cold air to the outer shell of the lower die to achieve the heat dissipation effect. When the injection molding is completed, the hydraulic cylinder drives the upper die and the lower die to separate. When the hydraulic cylinder drives the upper die to slide upward, the upper die will drive the cross bar to slide upward, the cross bar will drive the first fixing rod to slide upward, and the first fixing rod will drive the support rod to slide upward. Since the outer end of the support rod is inclined, and the inclination angle is the same as the inclination angle of the inner side surface of the limiting plate, when the support rod slides upward, it will slide obliquely along the inclination angle of the inner side surface of the limiting plate, so as to drive the air blower to slide obliquely through the support rod, and the air blower can be driven to slide to the top of the lower die. Since the air blower is obliquely arranged, the inner cavity of the lower die can be air-cooled, and then the cooling of the lower die can be accelerated. When the support rod slides, the slider will slide along the second fixing rod in the chute, and at the same time, the slider and the inner wall of the chute will squeeze the spring. When the upper die slides downward, the spring will rebound the slider, so as to drive the support rod to slide downward along the inner side surface of the limiting plate, so that the air blower slides obliquely to return to the initial state, and the outer shell of the lower die can be air-cooled to achieve the effect of cooling the outer shell of the injection molding machine. At the same time, the inside of the injection molding machine can be cooled after the injection molding is completed, so as to improve the internal cooling efficiency of the injection molding machine and further improve the plastic processing work efficiency.

Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] It is given by Figures 1-3 The present utility model includes a bottom plate 1. The center of the top of the bottom plate 1 is fixedly connected with a lower mold 2. Four hydraulic cylinders 3 are fixedly connected to the top of the bottom plate 1. The top of the four hydraulic cylinders 3 is fixedly connected with an upper mold 4. The upper mold 4 and the lower mold 2 are used in cooperation. A cross bar 5 is fixedly connected to the side of the upper mold 4. A first fixing rod 6 is fixedly connected to the bottom of the cross bar 5. A concave hole is provided on the side of the first fixing rod 6. A support rod 7 is slidably inserted in the concave hole. A fan 16 is fixedly connected to the inner side of the support rod 7. Limiting rods 14 are fixedly connected to both sides of the top of the bottom plate 1. A limiting plate 15 is fixedly connected to the top of the limiting rod 14. The inner part of the limiting plate 15 is inclined. The other end of the support rod 7 is inclined. The inclination angle of the support rod 7 is the same as the inclination angle of the limiting plate 15.

[0019] Sliding rods 9 are fixedly connected to the top and bottom of the inner cavity of the concave hole of the first fixing rod 6. The other ends of the two sliding rods 9 are fixedly connected with sliders 10. A chute 8 is provided in the inner cavity of the support rod 7. The slider 10 is slidably inserted in the chute 8. The arrangement of the sliding rod 9 and the slider 10 can improve the stability of the support rod 7.

[0020] A second fixing rod 11 is fixedly inserted in the inner cavity of the chute 8. A through hole 12 is provided on the side of the slider 10. The slider 10 is slidably sleeved on the second fixing rod 11 through the through hole 12. The arrangement of the second fixing rod 11 can make the support rod 7 more stable when sliding, thereby preventing the support rod 7 from tilting when sliding.

[0021] A spring 13 is sleeved on the circumferential surface of the second fixed rod 11. One end of the spring 13 is fixedly connected to the inner wall of the chute 8, and the other end of the spring 13 is fixedly connected to the side surface of the slider 10. The spring 13 can play a role in rebounding the support rod 7, so as to drive the support rod 7 to return to the initial state.

[0022] There are two fans 16, and the two fans 16 are respectively located on both sides above the bottom plate 1. The two fans 16 are both arranged obliquely downward, and the two fans 16 can improve the working efficiency of heat dissipation.

[0023] There are two limit plates 15, and the two limit plates 15 are respectively located on both sides of the top of the bottom plate 1. The two limit plates 15 are respectively arranged corresponding to the two support rods 7.

[0024] Working principle: During work, first, the hydraulic cylinder 3 drives the upper mold 4 to slide downward. The upper mold 4 will slide downward until it fits with the lower mold 2, so as to cooperate with the upper mold 4 and the lower mold 2. Then, injection molding is carried out through the injection port at the top of the upper mold 4. By electrically connecting to the fan 16, the fan 16 can blow cold air on the outer shell of the lower mold 2 to achieve the effect of heat dissipation. When the injection molding is completed, the hydraulic cylinder 3 drives the upper mold 4 to separate from the lower mold 2. When the hydraulic cylinder 3 drives the upper mold 4 to slide upward, the upper mold 4 will drive the cross bar 5 to slide upward, the cross bar 5 will drive the first fixed rod 6 to slide upward, and the first fixed rod 6 will drive the support rod 7 to slide upward. Since the outer end of the support rod 7 is inclined, and the inclination angle is the same as the inclination angle of the inner side surface of the limit plate 15, when the support rod 7 slides upward, it will slide obliquely along the inclination angle of the inner side surface of the limit plate 15. Thus, the fan 16 is driven to slide obliquely by the support rod 7, and the fan 16 can be driven to slide to the top of the lower mold 2. Since the fan 16 is arranged obliquely, the inner cavity of the lower mold 2 can be air-cooled, and then the cooling of the lower mold 2 can be accelerated. When the support rod 7 slides, the slider 10 will slide along the second fixed rod 11 in the chute 8. At the same time, the slider 10 and the inner wall of the chute 8 will squeeze the spring 13. When the upper mold 4 slides downward, the spring 13 will rebound the slider 10, so as to drive the support rod 7 to slide downward along the inner side surface of the limit plate 15, so that the fan 16 slides obliquely to return to the initial state, and the outer shell of the lower mold 2 can be air-cooled and cooled down.
