Detailed Embodiment

[0036] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0038] As Figure 1-Figure 5As shown in the figure, it is a structural diagram of a circulating cooling device for metal processing provided by an embodiment of the present invention, including a lower mold 1, an upper mold 2, a separation component, a shaking component, a cooling system, a reflux component, and a heat exchange component. The separation component is arranged on the lower mold 1, and the working end of the separation component is fixedly connected to the upper mold 2; the shaking component is installed on the cross plate 5 in the separation component, and the working end of the shaking component abuts against the C-shaped rod 6 in the separation component; the cooling system is arranged on the lower mold 1 and the upper mold 2 and is in a communicating state when the lower mold 1 and the upper mold 2 are in contact; the reflux component is arranged outside the lower mold 1; the heat exchange component is installed on the reflux component to exchange heat for the passing liquid.

[0039] In an example of the present invention, the driving lead screw 26 is driven by a driving motor installed at the bottom of the fixed block 3; both the driving motor and the rotating motor 9 are electrically connected to a controller 11 installed on the cross plate 5 for controlling the working processes of the driving motor and the rotating motor 9.

[0040] As Figure 1 , Figure 2 and Figure 3 As shown in the figure, as a preferred embodiment of the present invention, the separation component includes a fixed block 3, a positioning column 4, a cross plate 5, a C-shaped rod 6, and a driving lead screw 26;

[0041] The fixed blocks 3 are symmetrically installed on both sides of the lower mold 1. A positioning column 4 is installed on one of the fixed blocks 3, and a cross plate 5 is slidably arranged on the positioning column 4;

[0042] Among them, a driving lead screw 26 is rotatably arranged on the other fixed block 3. The driving lead screw 26 is connected to the cross plate 5, and a C-shaped rod 6 connected to the upper mold 2 is installed on the cross plate 5.

[0043] In an example of the present invention, when the driving motor works to drive the driving lead screw 26 to rotate, the driving lead screw 26 drives the cross plate 5 and the C-shaped rod 6 to slide along the positioning column 4, and the upper mold 2 moves synchronously therewith to adjust the height of the upper mold 2.

[0044] As Figure 1 and Figure 2 As shown in the figure, as another preferred embodiment of the present invention, the shaking component includes a fixing plate 7, an elastic support 8, a rotating motor 9, and a cam 10;

[0045] The fixing plate 7 is fixedly installed on the C-shaped rod 6, and an elastic support 8 is arranged between the cross plate 5 and the fixing plate 7;

[0046] A rotating motor 9 is fixedly installed on the upper surface of the cross plate 5, a cam 10 is installed at the shaft end of the rotating motor 9, and the cam 10 abuts against the C-shaped rod 6.

[0047] In one embodiment of the present invention, when the injection molding is completed and the mold is demolded, the rotating motor 9 drives the cam 10 to rotate synchronously, and the cam 10 pushes the shaped rod 6 to slide along the horizontal plate 5, and the upper mold 2 and the fixed plate 7 move synchronously. The elastic support member 8 is elastically deformed under the force, so that the upper mold 2 can be stably separated from the lower mold 1, thereby ensuring the quality of demolding.

[0048] like Figure 1 , Figure 3 and Figure 5 As shown, as another preferred embodiment of the present invention, the cooling system includes a filling pipe 12, a flow channel 1 13, a connecting pipe 14 and a flow channel 2 15;

[0049] The flow channel 1 13 is arranged in the lower mold 1, and the flow channel 2 15 is arranged in the upper mold 2;

[0050] The lower mold 1 is connected with a filling pipe 12 , and the flow channel 1 13 and the flow channel 2 15 are connected through a connecting pipe 14 .

[0051] In one example of the present invention, when the lower mold 1 is fitted with the upper mold 2, the coolant enters the runner 1 13 along the filling pipe 12 and enters the runner 2 15 along the connecting pipe 14, thereby cooling the lower mold 1 and the upper mold 2 as well as the metal workpiece inside. The coolant is finally discharged outward along the runner 2 15.

[0052] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the reflux assembly includes a heat exchange box 16, a guide pipe 17, a sleeve 18, a through hole 19, a pump body 21 and a pump body 21;

[0053] The heat exchange box 16 is arranged outside the lower mold 1, and a sleeve 18 is installed in the heat exchange box 16. A plurality of through holes 19 are arranged on the top of the sleeve 18. The sleeve 18 is also connected to the bottom of the second flow channel 15 through the outlet pipe 17.

[0054] The return pipe 20 is installed on the heat exchange box 16 , one end of the return pipe 20 is connected to the filling pipe 12 , and a pump body 21 is also installed on the return pipe 20 .

[0055] In one example of the present invention, the coolant at the end of the flow channel 15 enters the heat exchange box 16 along the outlet pipe 17, flows in the sleeve 18, and is finally discharged outward along the through hole 19. The working liquid of the pump body 21 flows outward along the return pipe 20, and is finally re-injected into the lower mold 1 and the upper mold 2 along the filling pipe 12, thereby realizing the circulation of the coolant.

[0056] like Figure 1 and Figure 4As shown, as another preferred embodiment of the present invention, the heat exchange assembly includes a spiral tube 22, a first infusion tube 23, a refrigerator 24, and a second infusion tube 25;

[0057] The spiral tube 22 is arranged in the lower mold 1 and is disposed outside the sleeve 18;

[0058] The first infusion tube 23 and the second infusion tube 25 are installed on the heat exchange box 16. The first infusion tube 23 is communicated with the top end of the spiral tube 22, and the second infusion tube 25 is communicated with the bottom end of the spiral tube 22;

[0059] A refrigerator 24 is also arranged between the first infusion tube 23 and the second infusion tube 25.

[0060] In an example of the present invention, when the coolant flows in the heat exchange box 16, the liquid flows along the spiral tube 22, the first infusion tube 23, and the second infusion tube 25, and when passing through the refrigerator 24, the coolant is cooled to facilitate circulating cooling.

[0061] In summary, the driving lead screw 26 drives the cross plate 5 and the C-shaped rod 6 to slide along the positioning column 4, and the upper mold 2 moves synchronously therewith to adjust the height of the upper mold 2. The coolant enters the first flow channel 13 along the filling tube 12 and enters the second flow channel 15 along the connecting tube 14 to cool the lower mold 1, the upper mold 2, and the internal metal workpiece. The coolant finally discharges outward along the second flow channel 15. The coolant enters the heat exchange box 16 along the lead-out tube 17 and flows in the sleeve 18, and finally discharges outward along the through hole 19. The pump body 21 makes the working liquid flow outward along the return tube 20 and finally re-injects into the lower mold 1 and the upper mold 2 along the filling tube 12, thus realizing the circulating flow of the coolant. The liquid flows along the spiral tube 22, the first infusion tube 23, and the second infusion tube 25, and when passing through the refrigerator 24, the coolant is cooled. When demolding after injection molding, the rotating motor 9 works to drive the cam 10 to rotate synchronously. The cam 10 pushes the C-shaped rod 6 to slide along the cross plate 5, and the upper mold 2 and the fixing plate 7 move synchronously. The elastic support member 8 is elastically deformed under force, so that the upper mold 2 can be stably separated from the lower mold 1, thereby ensuring the quality of demolding.
