[0023] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Example 1:

[0025] refer to Figure 2 A cooling device for processing a molded shell includes a base 1, a cooling box 2 is fixedly mounted on the upper surface of the base 1, the cooling box 2 is opened on the top, and a water inlet pipe 3 is connected to the middle of the cooling box 2 for conveying coolant into the cooling box 2, a drain pipe 4 is connected below the water inlet pipe 3, and the drain pipe 4 is located at the bottom of the inner cavity of the cooling box 2 for discharging the heated coolant.

[0026] refer to Figures 1-3Two sets of symmetrical transmission components are fixedly installed on the top of both sides of the cooling box 2. The transmission components include a first bracket 8 and a second bracket 9 fixedly installed on the left and right side panels of the cooling box 2. The first bracket 8 and the second bracket 9 are symmetrically arranged with the side panel as the center. A first pulley 10 is rotatably installed on the top of the first bracket 8, and a second pulley 11 is rotatably installed on the top of the second bracket 9.

[0027] refer to Figures 1-3 A first fixed plate 5 is fixedly installed on both sides of the cooling box 2, a servo motor 6 is fixedly installed on the surface of the first fixed plate 5, a winding wheel 7 is fixedly installed on the output end of the servo motor 6, and a rope 12 is installed for transmission between the winding wheel 7, the second pulley 11 and the first pulley 10. A screen frame 13 for placing the cylindrical shell is provided inside the cooling box 2, and two fixed blocks 14 are fixedly installed on the top of the screen frame 13, and the upper surface of the fixed block 14 is fixed to the end of the rope 12.

[0028] Furthermore, when in use, the servo motor 6 rotates to drive the winding wheel 7 to rotate, and the rope 12 is wound. Through the coordinated use of the first pulley 10 and the second pulley 11, the rope 12 changes direction to pull the screen frame 13 upward, and then the heat-treated mold cylinder shell is placed in the screen frame 13 through the robotic arm. Then, the servo motor 6 rotates in the opposite direction, so that the screen frame 13 moves down with the mold cylinder shell and is immersed in the coolant for cooling.

[0029] Example 2:

[0030] refer to Figures 1-4 A symmetrical second fixed plate 15 is fixedly installed on the surface of the front and rear side plates of the cooling box 2, and a cylinder 16 is fixedly installed on the surface of the second fixed plate 15. A mounting plate 17 is fixedly installed on the output end of the cylinder 16, and a plurality of cross bars 18 that pass through the cooling box 2 are fixedly installed on the surface of the mounting plate 17. The cross bar 18 slides with the cooling box 2, and the coolant is located below the cross bar 18. A striking head 19 is slidably installed at the end of the cross bar 18, and a spring 20 is fixedly connected between one end of the striking head 19 that slides in the cross bar 18 and the cross bar 18. Top blocks 21 used in conjunction with the striking head 19 are fixedly installed on both sides of the screen frame 13. The ends of the top block 21 and the striking head 19 are both conical, so that when the screen frame 13 moves up, the top block 21 can easily press the striking head 19 into the cross bar 18.

[0031] Furthermore, when the mold cylinder shell is about to finish cooling, the cylinder 16 pulls the mounting plate 17 to move, thereby driving the cross bar 18 to move forward, so that the impact head 19 is squeezed by the screen frame 13. At this time, the cooling of the cylinder shell is completed, and the rope 12 pulls the screen frame 13 upward. While the screen frame 13 moves upward, the top block 21 squeezes the impact head 19, presses the impact head 19 into the cross bar 18 and squeezes the spring 20. The screen frame 13 continues to move upward, so that the top block 21 is separated from the impact head 19. At this time, the impact head 19 is acted upon by the spring 20, so that the impact head 19 hits the screen frame 13. Multiple top blocks 21 are set so that the impact head 19 reciprocates and hits the screen frame 13, thereby causing the screen frame 13 to vibrate, and then the coolant is quickly separated from the mold cylinder shell, which facilitates the subsequent drying work and speeds up work efficiency.

[0032] refer to Figure 1 and Figure 3 A hot air blower 22 is fixedly installed on the upper surface of the base 1 and located on one side of the cooling box 2. The top of the hot air blower 22 is connected to a duct 23. A meandering air duct 24 located above the screen frame 13 is fixedly installed on the inner surface of the cooling box 2. Several air nozzles 25 are fixedly installed on the surface of the air duct 24, and the air duct 24 is connected to the duct 23.

[0033] Furthermore, during use, when the screen frame 13 rises to the air duct 24 and stops, the hot air blower 22 is started and blows hot air toward the screen frame 13 through the air nozzle 25, thereby drying the coolant adhering to the surface of the mold cylinder shell and preventing residual moisture on the surface from causing rust, spots, etc. on the parts during subsequent processing or use, affecting the appearance and performance of the mold cylinder shell. After drying, the cylinder 16 pulls the crossbar 18.

[0034] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0035] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
