Description

Technical Field

[0001] The present invention relates to the technical field of plastic brackets, and in particular to a cooling device for producing plastic brackets. Background Art

[0002] Cooling a plastic bracket is a critical step in the injection molding process, ensuring the rapid and uniform solidification of the molten plastic within the mold by controlling mold temperature, cooling medium, and process parameters, thereby ensuring the dimensional stability, mechanical properties, and production efficiency of the plastic bracket. Improper cooling can easily lead to deformation, sink marks, and internal stress, making it particularly crucial for bracket parts with complex structures and uneven wall thicknesses.

[0003] For example, Chinese patent publication number CN216760774U discloses a water-cooling device for producing plastic materials, belonging to the technical field of plastic production equipment. The device includes a bracket fixedly connected to a water-cooling trough, a plurality of mounting rods fixedly connected between the inner walls of the water-cooling trough, the plurality of mounting rods being evenly spaced along the length of the water-cooling trough, a plurality of rollers rotatably connected to the mounting rods at even intervals, an annular groove being formed on the outer wall of the roller, a guide wheel rotatably connected to the upper surface of each end of the water-cooling trough, and a cooling mechanism for cooling cooling water being provided on the inner wall of the water-cooling trough.

[0004] The above-mentioned cited documents have the advantages of facilitating the cooling of the cooling water in the water-cooling tank and improving the cooling efficiency of the plastic.

[0005] However, when the above-mentioned plastic water cooling equipment is applied to the cooling processing of the plastic bracket, the plastic bracket floats above the coolant when it is cooled in the water cooling box. When the coolant is circulated in the water cooling box, the plastic bracket floats on the surface of the coolant and cannot be fully immersed. The contact area between the coolant and the plastic bracket is small, and the cooling effect is poor. In addition, the floating plastic bracket is prone to aggregation at the inlet, which further affects the cooling effect. In addition, it is not convenient to centrally export the cooled plastic bracket. Summary of the Invention

[0006] The purpose of the present invention is to provide a cooling device for the production of plastic brackets, which can achieve full contact between the plastic brackets and the water-cooling liquid in the water-cooling box, thereby improving the cooling effect, and can avoid the plastic brackets from gathering at the inlet, which is not conducive to the overall cooling effect and centralized export processing procedures.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: A cooling device for producing plastic brackets, comprising a water cooling box, with mounting plates fixedly mounted on both sides of the top of the water cooling box, and further comprising:

[0016] Preferably, the longitudinal plates on both sides are staggered and arranged in the same plane, and the first transverse plate and the capsule cavity on the same side are located on the same perpendicular midline.

[0017] Preferably, a water collecting pipe is fixedly installed at the output end of the circulating water pump, the water collecting pipe is connected to the inner cavity of the bladder cavity on the same side, and a one-way valve is installed between the bladder cavity and the water collecting pipe.

The outer dial plate outside the circumference of the roller can dial the drifting plastic bracket and pour it out to the outside of the top opening of the water-cooling box, thereby realizing the centralized export of the cooled plastic bracket.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1:

[0033] This embodiment introduces a cooling device for producing plastic brackets. Figure 1-Figure 4 As shown, it includes a water cooling box 100, with mounting plates 11 fixedly mounted on both sides of the top of the water cooling box 100, and further includes:

[0034] The lifting frame 200 is movably mounted on the top of the mounting plate 11. Guide plates 21 are fixedly mounted on both sides of the top of the two sets of mounting plates 11. The middle and bottom of the lifting frame 200 are respectively integrally formed with a first transverse plate 22 and a second transverse plate 23. The side of the second transverse plate 23 is uniformly spaced and integrally formed with longitudinal shift plates 24.

[0035] The circulating water pump 300 is fixedly installed on one side of the outside of the water cooling box 100. High-pressure nozzles 31 are fixedly installed at equal intervals on the adjacent surfaces of the two sets of mounting plates 11. The bottoms of the two sets of mounting plates 11 are respectively fixedly installed with sac cavities 33. The ends of the high-pressure nozzles 31 on the same side are connected to the inner cavity of the sac cavities 33.

[0036] Among them, a guide plate 12 is fixedly installed on one side of the top opening of the water-cooling box 100, and a roller 400 is installed on the side of the top opening of the water-cooling box 100 away from the guide plate 12. A connecting shaft 41 is connected to one side of the roller 400. Both ends of the connecting shaft 41 are rotatably installed at the top opening of the water-cooling box 100. The back end of the connecting shaft 41 and the output end of the servo motor 500 on the same side are respectively fixed with a synchronous pulley 43. The external fixed sleeves of the two sets of synchronous pulleys 43 are provided with synchronous belts 44. The outer circumference of the roller 400 is fixed with equal intervals. An external dial plate 42 is fixedly installed, and there is a gap between the external dial plate 42 and the top opening of the water cooling box 100. The servo motor 500 on the same side as the synchronous belt 44 can synchronously drive the synchronous pulley 43 and the synchronous belt 44, so that multiple groups of external dial plates 42 on the outer circumference of the roller 400 are synchronously driven and rotate in a circle on the other side of the top opening of the water cooling box 100. The external dial plate 42 outside the circumference of the roller 400 can dial the plastic bracket that drifts over and pour it out to the outside of the top opening of the water cooling box 100.

[0037] Among them, a connecting seat 20 is fixedly installed in the middle of the bottom surface of the lifting frame 200, and a pin shaft 201 is connected to the outside of the connecting seat 20. The end of the connecting rod 51 away from the swing arm 52 is hinged to the end of the pin shaft 201. The two sides of the top of the two groups of guide plates 12 are respectively penetrated with a through groove 202. Each group of guide plates 21 corresponds to the through groove 202. The two ends of the lifting frame 200 are movably inserted into the inner wall of the corresponding guide plate 21. The swing arm 52 is driven to rotate by the output end of the two groups of servo motors 500. The two ends are hingedly connected to the corresponding connecting rods 51 to form a rocker structure, forming a reciprocating swing mechanism, which can drive the corresponding lifting frame 200 and the bottom connecting seat 20 to reciprocate up and down. When the two sets of lifting frames 200 are raised and lowered in the corresponding guide plates 21, the two sets of parallel and staggered longitudinal paddles 24 at the bottom can stir the water-cooling liquid in the water-cooling box 100 to form a turbulent flow, so that the plastic bracket floating on the water-cooling liquid can be agitated by the water flow, so that the upper and lower surfaces can be soaked by the water-cooling liquid.

[0038] like Figure 1-Figure 3 As shown, in this embodiment, after the plastic bracket is injection molded, it can be guided by the guide plate 12 and introduced into the water cooling box 100, and the water cooling liquid inside the water cooling box 100 can be extracted by an external circulation pump, cooled, and then re-introduced, so that the plastic bracket introduced into the water cooling box 100 can be circulated and cooled. The cooling of the plastic bracket by the water cooling liquid in the water cooling box 100 is a conventional technical solution and will not be described in detail here.

[0039] like Figure 5 、 Figure 6As shown, in this embodiment, the swing arm 52 is driven to rotate by the output ends of the two sets of servo motors 500, and the ends of the swing arms 52 are hinged with the corresponding connecting rods 51 to form a rocker structure, forming a reciprocating swing mechanism, thereby driving the corresponding lifting frames 200 and the bottom connecting seat 20 to reciprocate up and down. When the two sets of lifting frames 200 are lifted and lowered in the corresponding guide plates 21, the two sets of parallel and staggered longitudinal paddles 24 at the bottom can stir the water-cooling liquid in the water-cooling box 100 to form a turbulent flow, so that the plastic bracket floating on the water-cooling liquid can be agitated by the water flow, so that the upper and lower surfaces can be soaked by the water-cooling liquid. When the first horizontal plate 22 moves up and down in the water-cooling box 100, it can squeeze the corresponding sac cavity 33 above, so that the water-cooling liquid in the sac cavity 33 enters the multiple sets of high-pressure nozzles 31, impacting the plastic bracket floating on the water-cooling liquid, so that the plastic bracket can be completely immersed in the water-cooling liquid, thereby improving the overall cooling effect.

[0040] Example 2:

[0041] Based on Example 1, this example introduces a cooling device for producing plastic brackets, such as Figure 5 、 Figure 7 As shown, the servo motor 500 is installed at the top of both sides of the water cooling box 100. The output end of the servo motor 500 is hinged with a swing arm 52. The end of the swing arm 52 away from the servo motor 500 is hinged with a connecting rod 51. The end of the connecting rod 51 away from the swing arm 52 is movably assembled with the lifting frame 200 on the same side.

[0042] Among them, the longitudinal plates 24 on both sides are staggered in the same plane, the first horizontal plate 22 and the sac cavity 33 on the same side are on the same median vertical line, and a water collecting pipe 32 is fixedly installed at the output end of the circulating water pump 300. The water collecting pipe 32 is connected to the inner cavity of the sac cavity 33 on the same side, and a one-way valve is installed between the sac cavity 33 and the water collecting pipe 32. The circulating water pump 300 on the same side cooperates with the water collecting pipe 32 and the one-way valve to synchronously supply water to the sac cavity 33. When the first horizontal plate 22 moves up and down in the water cooling box 100, it can squeeze the corresponding sac cavity 33 above, so that the water-cooling liquid in the sac cavity 33 enters the multiple sets of high-pressure nozzles 31, and impacts the plastic bracket floating on the water-cooling liquid, so that the plastic bracket can be completely immersed in the water-cooling liquid, thereby improving the overall cooling effect.

[0043] Among them, the first horizontal plate 22 is located in the inner cavity of the water-cooling box 100, and the angle between the high-pressure nozzle 31 and the bottom plane of the guide plate 21 is thirty degrees. The mounting brackets 50 are fixedly installed at the top of both sides of the water-cooling box 100, and the servo motor 500 is fixedly installed on the top of the corresponding mounting bracket 50. When the high-pressure nozzle 31 sprays the coolant into the top of the water-cooling box 100, the plastic bracket floating on the coolant is impacted, so that the plastic bracket can be completely immersed in the coolant, thereby improving the overall cooling effect. Since the angle between the high-pressure nozzle 31 and the top surface of the water-cooling box 100 is thirty degrees, the floating plastic bracket can be moved from left to right after the impact, thereby avoiding the formation of aggregation of the plastic bracket at the guide plate 12.

[0044] like Figure 5-Figure 7 As shown, in this embodiment, when the high-pressure nozzle 31 sprays the coolant into the top of the water-cooling box 100, since the angle between the high-pressure nozzle 31 and the top surface of the water-cooling box 100 is thirty degrees, the floating plastic bracket can be impacted and moved from left to right, thereby avoiding the accumulation of plastic brackets at the guide plate 12, and the roller 400 can rotate in a circle on the other side of the top opening of the water-cooling box 100 in cooperation with the synchronous belt 44, the synchronous pulley 43 and the servo motor 500 on the same side. The outer dial plate 42 outside the circle of the roller 400 can dial the drifting plastic bracket and pour it out to the outside of the top opening of the water-cooling box 100, thereby realizing the centralized export of the cooled plastic bracket.

[0045] Working principle: When the plastic bracket is cooled inside the water cooling box 100, the plastic bracket can be guided by the guide plate 12 and introduced into the water cooling box 100 after injection molding.

[0046] The swing arm 52 is driven to rotate by the output ends of the two sets of servo motors 500. The ends of the swing arms 52 are hinged to the corresponding connecting rods 51 to form a rocker arm structure, forming a reciprocating swing mechanism, thereby driving the corresponding lifting frames 200 and the bottom connecting seat 20 to reciprocate up and down. When the two sets of lifting frames 200 are lifted and lowered in the corresponding guide plates 21, the two sets of parallel and staggered longitudinal paddles 24 at the bottom can stir the water-cooling liquid in the water-cooling box 100 to form a turbulent flow, so that the plastic bracket floating on the water-cooling liquid can be agitated by the water flow, so that the upper and lower surfaces can be soaked by the water-cooling liquid. When the first horizontal plate 22 moves up and down in the water-cooling box 100, it can squeeze the corresponding sac cavity 33 above, so that the water-cooling liquid in the sac cavity 33 enters the multiple sets of high-pressure nozzles 31, impacting the plastic bracket floating on the water-cooling liquid, so that the plastic bracket can be completely immersed in the water-cooling liquid;

[0047] When the high-pressure nozzle 31 sprays the coolant into the top of the water-cooling box 100, since the angle between the high-pressure nozzle 31 and the top surface of the water-cooling box 100 is thirty degrees, the floating plastic bracket can be impacted and moved from left to right, thereby avoiding the accumulation of plastic brackets at the guide plate 12. The roller 400 can rotate in a circle on the other side of the top opening of the water-cooling box 100 in cooperation with the synchronous belt 44, the synchronous pulley 43 and the servo motor 500 on the same side. The outer dial plate 42 outside the circle of the roller 400 can dial the drifting plastic bracket and pour it out to the outside of the top opening of the water-cooling box 100, thereby realizing the centralized export of the cooled plastic bracket.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
